Look beyond disease activity in treating SLE patients
DESTIN, FLA. – Patients with lupus are at increased risk for a number of long-term health issues that should be considered during the course of their care, according to Dr. Susan Manzi.
Bone disease, cardiovascular disease, cancer, and infection are particular areas of concern, Dr. Manzi said at the Congress of Clinical Rheumatology.
• Bone health. Women with systemic lupus erythematosus are known to be at increased risk for fractures. A 1999 retrospective cohort study, for example, showed that the observed number of nontraumatic fractures in more than 700 women with SLE was about fivefold greater than in the general population (Arthritis Rheum. 1999;42:882-90).
The standardized morbidity ratios ranged from 2.4 to 12.1 for various age groups, with the greatest risks in those aged 18-24 years (12.1), 45-64 years (7.6), and 70 years and older (4.9).
"We know that we cause a lot of the bone loss; we know that the bone loss may be part of the underlying disease. The fact is it’s there. We need to monitor for it and treat it," Dr. Manzi said. She noted that American College of Rheumatology guidelines are available to help in reducing fracture risk in patients with connective tissue diseases, such as lupus (Arthritis Care Res. 2010;62:1515-26).
• Cardiovascular health. Similarly, myocardial infarctions per 1,000 person-years are significantly greater among those with SLE than in the general population, according to the 1997 Framingham Offspring Study.
In that study, Dr. Manzi and her colleagues found that the incidence of MI was higher in SLE patients in every age category. The risk was 50-fold greater in those with SLE who were aged 35-44 years, compared with the overall study population (Am. J. Epidemiol. 1997;145:408-15).
Of note, in 2011 the American Heart Association officially recognized women with lupus and rheumatoid arthritis as at-risk groups for cardiovascular disease, and developed treatment and management recommendations for these groups, said Dr. Manzi, director of the Lupus Center of Excellence at the University of Pittsburgh. The AHA noted that SLE and RA may be unrecognized risk factors and that women with these conditions, even without clinically relevant cardiovascular disease, should be considered at risk and should be screened accordingly. The AHA recommendations "actually suggested that any woman who comes in with a cardiovascular event, particularly if it’s unexplained and they are young, should be screened for lupus and rheumatoid arthritis," she said.
• Cancer. In a 2005 study of more than 13,000 women from 30 centers, patients with lupus had a 20% increased risk for cancer, compared with the general population. A recent update similarly showed a 15%-20% increased risk (J. Autoimmun. 2013;42:130-5).
The greatest risk was for hematologic cancers, such as lymphomas and leukemia. Lung cancer and thyroid cancer were also increased in the lupus patients. A trend toward an increased risk of cervical and vulvar cancers was also noted, which could be associated with human papillomavirus infection. "This means we should be doing more paps and pelvics," she said.
Interestingly, women with SLE appear to have a reduced risk of breast, ovarian, and endometrial cancers, possibly as a result of avoidance of hormone replacement therapy, she said (Arthritis Rheum. 2005;52:1481-90).
• Infection. Patients with lupus are known to have an increased risk for infection, and it is important to exercise caution when using live attenuated vaccines. These include the herpes zoster vaccine; bacillus Calmette-Guérin tuberculosis vaccine; oral typhoid vaccine; measles, mumps, and rubella vaccine; varicella vaccine; oral polio vaccine; intranasal influenza vaccine; yellow fever vaccine; and endemic typhus vaccine, Dr. Manzi said.
These vaccines are not recommended for SLE patients being treated with immunosuppressive or biologic medications or with low immunoglobulins or hypocomplementemia.
Dr. Manzi has served as a consultant and/or advisory board member for Bristol-Myers Squibb, Exagen Diagnostics, Genentech, and other companies.

EXPERT ANALYSIS FROM THE CONGRESS OF CLINICAL RHEUMATOLOGY
Benefits of PCV7 vaccination persisted over a decade
A decline in both pediatric and adult pneumonia-related hospitalizations following the 2000 introduction of the 7-valent pneumococcal vaccine, or PCV7, into the U.S. childhood immunization schedule was sustained over the next decade, a comprehensive assessment of U.S. hospitalizations showed.
The findings allay concerns about whether increases in disease caused by nonvaccine serotypes had eroded the gains made in the years following the PCV7 introduction, according to Dr. Marie R. Griffin of Vanderbilt University, Nashville, Tenn., and her colleagues.
Compared with the estimated annual rates of hospitalization for pneumonia from 1997 through 1999 (the 3 years prior to PCV7 introduction), the rates from 2007 through 2009 (the 3 years prior to a switch to 13-valent pneumococcal conjugate vaccine, or PCV13, in 2010) indicate that the annual rate among children younger than age 2 years declined by 551.1/100,000 children, or 43.2%, which translates to 47,000 fewer hospitalizations annually. The rates among adults aged 85 years or older declined by 1,300.8/100,000, or 22.8%, which translates to 73,000 fewer hospitalizations, the investigators reported in the July 11 issue of the New England Journal of Medicine.
Although the declines were steepest in those at the "extremes of age," the rates also declined for adults aged 18-39 years, 65-74 years, and 75-84 years (by 8.4, 85.3, and 359.8/100,000, respectively), they said (N. Engl. J. Med. 2013;369:155-63).
"The overall, age-adjusted annual reduction in hospitalization rates from the pre-PCV7 years was 54.8 hospitalizations per 100,000, representing an estimated 168,000 fewer hospitalizations in 2009 than would have been expected," Dr. Griffin and her colleagues wrote.
Annual hospitalization rates for this study were estimated based on hospitalization for pneumonia from any cause as identified using the Nationwide Inpatient Sample database – the largest all-payer U.S. inpatient care database, which includes data from about 8 million hospitalizations each year. Data included in this study were for patients with a first-listed discharge diagnosis of pneumonia or a first-listed discharge diagnosis of meningitis, septicemia, or empyema in addition to a diagnosis of pneumonia.
The marked decline in pneumococcal disease among both vaccinated and unvaccinated individuals is attributable to "herd" immunity provided by PCV7, and although it was previously shown that the introduction of PCV7 had resulted in a nearly 40% reduction in pneumonia-related hospitalizations within 4 years, an increase in disease caused by nonvaccine serotypes – particularly serotype 19A – raised concerns that this "serotype replacement" represented a step backward, the investigators explained.
The findings suggest that these concerns were unwarranted.
Although the declines in hospitalization among adults was more modest and emerged more slowly than the "remarkable early declines" seen in children, they did result in "large absolute overall reductions in hospitalizations for pneumonia," the investigators said.
Still, unvaccinated age groups continue to have some residual burden of pneumococcal disease due to serotypes covered by PCV7, they noted.
"It is not known whether the direct vaccination of adults with PCV13 would prevent pneumonia in adults and whether such efforts would add substantially to the indirect benefits generated by the ongoing PCV13 vaccination program in infants, which may now be reducing the transmission of the additional six vaccine serotypes," they said.
This study was supported by grants from the Centers for Disease Control and Prevention and the Thrasher Research Fund. Dr. Griffin reported receiving grant support through her institution from Pfizer, and coauthor Dr. Carlos G. Grijalva reported receiving consulting fees from GlaxoSmithKline, and grant support through his institution from Pfizer. The remaining authors reported having no relevant financial disclosures.

Medicare Advantage patients get fewer CV procedures
Medicare beneficiaries enrolled in the Medicare Advantage programs have lower rates of angiography and percutaneous coronary intervention procedures than do those enrolled in fee-for-service Medicare, but procedure rates in both groups vary widely by geographic region, according to findings from a large cross-sectional study.
Compared with more than 5 million Medicare fee-for-service patients from across 32 hospital referral regions in 12 states, the more than 878,000 Medicare Advantage patients included in the study had lower age-, sex-, race-, and income-adjusted angiography procedure rates (16.5 vs. 25.9 per 1,000 person-years) and percutaneous coronary intervention (PCI) procedure rates (6.8 vs. 9.8). The differences persisted after adjusting for additional cardiac risk factors in the Medicare Advantage beneficiaries, Dr. Daniel D. Matlock of the University of Colorado, Aurora, and his colleagues reported July 9 in JAMA.
The rates of coronary artery bypass graft (CABG) surgery were similar in the two groups (3.1 vs. 3.4), as were the rates of urgent angiography and PCI (3.9 vs. 4.3, and 2.4 vs. 2.7, respectively), the investigators reported (JAMA 2013;310:155-62).
In addition to the variations in procedure rates by Medicare plan type, wide variations in procedure rates were also noted across hospital referral regions. For example, angiography rates per 1,000 person-years ranged from 9.8 to 40.6 for Medicare Advantage beneficiaries, and from 15.7 to 44.3 for Medicare fee-for-service beneficiaries; the PCI rates ranged from 3.5 to 16.8 and from 4.7 to 16.1 for the groups, respectively; and the rates for CABG surgery ranged from 1.5 to 6.1, and from 2.5 to 6.0 for the groups, respectively. The degree of variation was similar in the two groups, , the investigators noted.
No significant correlation was seen between the Medicare Advantage and fee-for-service beneficiaries for angiography across the regions, and only modest correlations were seen for PCI and CABG surgery, they said.
"The finding that Medicare Advantage patients have lower rates of angiography and PCI underscores the need for additional research to determine the extent to which this is attributable to differences in population characteristics, more efficient utilization of procedures among Medicare Advantage patients (i.e., overutilization in Medicare FFS), or harmfully restrictive management of utilization in Medicare Advantage," the investigators wrote.
The similarities in the degree of regional variations in the two groups suggest that "factors beyond payment mechanisms influence practice variations," they noted, adding that the variation in this study may be a function of the availability of the procedures – a possibility that they argued deserves further study, along with patient-level factors and "implicit professional norms or the local practice culture."
The investigators point out that "geographic variation in health services in the Medicare fee-for-service population has fueled the perception of an inefficient, ineffective U.S. health care system," and they argue that shedding light on the sources of variability will, therefore, remain an important "research and quality improvement endeavor" until the causes of geographic variation are understood.
The study was supported by the National Heart, Lung, and Blood Institute and the Cardiovascular Research Network. Medicare data were obtained under an Agency for Healthcare Research and Quality grant.

"Perhaps it is time to recognize the current practice variation as a potential indicator of a weakness of the current approach to decision making," he wrote, explaining that while patients may have an interest in participating in decisions, clinicians "are often unaware of patient preferences, cannot predict them, and weigh risks and benefits differently than their patients" (JAMA 2013;310:151-2).
The findings of Dr. Matlock and colleagues reinforce the need to ensure that practice variation "is not evidence of care that is not truly patient centered," he wrote, adding that more emphasis on producing innovations to optimize decision making, and to ensure that variation is based on patient differences rather than on other factors, is needed.
Potential next steps include:
• Setting standards for high-quality decisions and developing metrics for assessing decision quality, promoting performance, and encouraging quality improvement activities.
• Codifying the skills in guiding high-quality decisions, teaching the science of clinical decision making, and establishing it as a competency for medical professionals.
• Developing tools to facilitate high-quality patient-centered decisions.
"Too little attention, for too long, has been directed toward ensuring the quality of preference-sensitive patient decisions. ... Ultimately, the goal is not to eliminate variation but to guarantee that its presence throughout health care systems derives from the needs and preferences of patients," he said.

He reported receiving a research grant from Medtronic through Yale University, and serving as chair of a cardiac scientific advisory board for UnitedHealth.

Compared with more than 5 million Medicare fee-for-service patients from across 32 hospital referral regions in 12 states, the more than 878,000 Medicare Advantage patients included in the study had lower age-, sex-, race-, and income-adjusted angiography procedure rates (16.5 vs. 25.9 per 1,000 person-years) and percutaneous coronary intervention (PCI) procedure rates (6.8 vs. 9.8). The differences persisted after adjusting for additional cardiac risk factors in the Medicare Advantage beneficiaries, Dr. Daniel D. Matlock of the University of Colorado, Aurora, and his colleagues reported July 9 in JAMA.
The rates of coronary artery bypass graft (CABG) surgery were similar in the two groups (3.1 vs. 3.4), as were the rates of urgent angiography and PCI (3.9 vs. 4.3, and 2.4 vs. 2.7, respectively), the investigators reported (JAMA 2013;310:155-62).
In addition to the variations in procedure rates by Medicare plan type, wide variations in procedure rates were also noted across hospital referral regions. For example, angiography rates per 1,000 person-years ranged from 9.8 to 40.6 for Medicare Advantage beneficiaries, and from 15.7 to 44.3 for Medicare fee-for-service beneficiaries; the PCI rates ranged from 3.5 to 16.8 and from 4.7 to 16.1 for the groups, respectively; and the rates for CABG surgery ranged from 1.5 to 6.1, and from 2.5 to 6.0 for the groups, respectively. The degree of variation was similar in the two groups, , the investigators noted.
No significant correlation was seen between the Medicare Advantage and fee-for-service beneficiaries for angiography across the regions, and only modest correlations were seen for PCI and CABG surgery, they said.
"The finding that Medicare Advantage patients have lower rates of angiography and PCI underscores the need for additional research to determine the extent to which this is attributable to differences in population characteristics, more efficient utilization of procedures among Medicare Advantage patients (i.e., overutilization in Medicare FFS), or harmfully restrictive management of utilization in Medicare Advantage," the investigators wrote.
The similarities in the degree of regional variations in the two groups suggest that "factors beyond payment mechanisms influence practice variations," they noted, adding that the variation in this study may be a function of the availability of the procedures – a possibility that they argued deserves further study, along with patient-level factors and "implicit professional norms or the local practice culture."
The investigators point out that "geographic variation in health services in the Medicare fee-for-service population has fueled the perception of an inefficient, ineffective U.S. health care system," and they argue that shedding light on the sources of variability will, therefore, remain an important "research and quality improvement endeavor" until the causes of geographic variation are understood.

Low vitamin D effects on CHD risk vary by race
Associations between serum 25-hydoxyvitamin D concentration and coronary heart disease vary by race, according to findings from the Multi-Ethnic Study of Atherosclerosis (MESA).
Of 6,436 participants in the community-based, prospective cohort study, 361 experienced an incident CHD event during a median of 8.5 years of follow-up. A low baseline serum 25-hydroxyvitamin D (25[OH]D) level was associated with a greater risk of an event in 167 white participants (hazard ratio, 1.26 per 10-ng/mL decrement) and in 27 Chinese participants (HR, 1.67 per 10-ng/mL decrement), but not in 94 black participants or 73 Hispanic participants (HR, 0.93 and 1.01 per 10-ng/mL decrement), Cassianne Robinson-Cohen, Ph.D., of the University of Washington, Seattle, and her colleagues reported online July 9 in JAMA.
"Differences in associations across race/ethnicity groups were consistent for both a broad and restricted definition of CHD and persisted after adjustment for known CHD risk factors," the investigators said.
The findings require confirmation, but suggest that until such confirmation is available, the results of studies evaluating the effects of 25(OH)D in ethnically homogeneous populations should not be extrapolated to other racial or ethnic populations, the investigators said, noting that a low 25(OH)D level has consistently been linked with CHD in study populations composed largely or entirely of white subjects, but that the association has not been studied rigorously in other populations (JAMA 2013;310:179-88).
Study subjects were adults aged 45-84 years (mean, 62 years) who were free of known cardiovascular disease and who were recruited between July 2000 and September 2002. The subjects were followed via telephone every 9-12 months to assess for myocardial infarction, angina, cardiac arrest, or CHD death. Diagnoses were confirmed via death certificates and/or medical record review.
As for possible explanations for the racial and ethnic differences observed in this study, the data suggest that biologic differences account for much of the heterogeneity, the investigators said, explaining that although "results were robust ... we are unable to discern characteristics that could conceivably cause differential confounding by race, and chance findings are unlikely – at least for black vs. white comparison – due to reasonable numbers of events in each race."
Additionally, the lack of any trend toward association in blacks, the statistically significant global and black vs. white P values for interaction, and the fact that findings of studies looking at the associations of 25(OH)D with other health outcomes also support differing associations by race, support a biologic explanation, they said.
The findings in Hispanic and Chinese populations in this study, however, should be interpreted with caution, because the sample sizes for these groups were relatively small, and the number of events was low; additional studies of 25(OH)D and health outcomes are needed in these populations, they said.
Though limited by potential confounding (many unhealthy characteristics are linked with lower 25[OH]D concentrations) and by low power for detecting associations of small magnitude within individual racial and ethnic groups, the findings are bolstered by the large multiethnic population; the evaluation of adjudicated incident CHD events over a relatively long follow-up time; the use of an accurate assay for measuring 25(OH)D; and careful, high-quality approaches to measuring 25(OH)D.
In addition to studies to confirm these findings, well-powered clinical trials are also needed to evaluate the effects of vitamin D supplements on CHD risk, the investigators said, noting that at least five such trials are currently underway, including one (the Vitamin D and Omega-3 Trial, or VITAL) that is targeting enrollment of a large multiracial study population.
The current study was funded by grants from the National Heart, Lung, and Blood Institute. Dr. Robinson-Cohen reported having no relevant financial disclosures, but other study authors reported receiving grant funding, travel accommodations, and/or payment for lectures from the National Institutes of Health, Amgen, and/or Abbott Laboratories.
The findings by Dr. Robinson-Cohen and her colleagues in their "well-designed investigation," which helps to "unravel the complex associations between race/ethnicity, 25(OH)D, and CHD," also raise important questions about those associations, Dr. Keith C. Norris and Dr. Sandra F. Williams wrote in an editorial.
These include questions about whether seasonal variability in concentrations might vary across racial and ethnic groups and influence previously reported findings (unlikely, based on the findings, they said); whether racial ethnic differences in those associations may be driven by differential regulation of parathyroid hormone (though not addressed in the study, this remains plausible based on previous findings, they noted); and whether racial and ethnic variations in vitamin D–mediated cellular activation/metabolism might contribute to the observed differences (JAMA 2013;310:153-4).
With regard to the third question, the data from the study raise the possibility that differences in up- or down-regulation of key pathways may underlie the racial and ethnic differences observed in the MESA cohort.
The study adds important insights about race/ethnicity, 25[OH]D concentrations, and CHD risk, they said, adding that "the heterogeneity of the findings underscores the importance of further exploring racial differences in clinical research and of not immediately generalizing results from ethnically homogeneous populations to other groups that may differ by race/ethnicity, sex, or age."

Updated guideline urges discussion of breast cancer chemoprevention
Tamoxifen for the prevention of breast cancer should be discussed with women aged 35 years or older who are at increased risk for the disease, according to an updated clinical practice guideline from the American Society of Clinical Oncology.
The use of raloxifene and exemestane should be discussed with postmenopausal women who are at increased risk for the disease, according to the update – the third since the guideline, entitled "Use of Pharmacologic Interventions for Breast Cancer Risk Reduction," was first published in 1999, and the first since 2009 (J. Clin. Onco. 2009;27:3235-58).
The new update includes stronger wording regarding discussion about the selective estrogen-receptor modulators tamoxifen and raloxifene, compared with the 2009 version, which stated that tamoxifen and raloxifene "may be offered" to women at increased risk.
"The committee felt that a stronger statement recommending the use of tamoxifen and raloxifene was needed given the weight of evidence from phase III randomized trials demonstrating a reduction in breast cancer risk for both tamoxifen and raloxifene," Update Committee cochair, Dr. Kala Visvanathan of Johns Hopkins Medical Institutions, Baltimore, and the other committee members reported (J. Clin. Oncol. 2013 July 8 [doi 10.1200/JCO.2013.49.3122]).
The guideline recommendations, which were published online on July 8 in the Journal of Clinical Oncology, and which are limited to pharmacologic interventions, specifically call for discussing with patients the options of:
• Oral tamoxifen treatment at a dose of 20 mg daily for 5 years to reduce the risk of estrogen receptor- (ER) positive invasive breast cancer in both pre- and postmenopausal women aged at least 35 years who are at increased risk of breast cancer or who have lobular carcinoma in situ (LCIS). Increased risk is defined as a 5-year projected absolute risk of 1.66% or greater according to the National Cancer Institute Breast Cancer Risk Assessment Tool or an equivalent measure. This "strong, evidence-based recommendation" is based on data from multiple randomized, controlled trials showing that the risk reduction benefit of this treatment continues for at least 10 years in these patients.
• Oral raloxifene treatment at a dose of 60 mg daily for 5 years to reduce the risk of ER-positive invasive breast cancer in postmenopausal women aged at least 35 years who are at increased risk or who have LCIS. This "strong, evidence-based recommendation" also is based on data from multiple randomized, controlled trials.
• Oral exemestane at a dose of 25 mg daily for 5 years as an alternative to tamoxifen or raloxifene to reduce the risk of ER-positive invasive breast cancer in postmenopausal women aged at least 35 years who are at increased risk of breast cancer or who have LCIS. This "moderate, evidence-based recommendation" is based on encouraging evidence from a single randomized, controlled trial of the aromatase inhibitor, which is approved for the treatment of breast cancer but not for breast cancer prevention.
Tamoxifen and raloxifene are not recommended for use in women with a history of deep vein thrombosis, pulmonary embolus, stroke, or transient ischemic attack, nor are they recommended during prolonged immobilization. Tamoxifen is not recommended in women who are pregnant or who may become pregnant or in women who are nursing, and it should not be used in combination with hormone therapy. Exemestane should not be used in premenopausal women, according to the guideline.
"Discussions with patient and health care providers should include both the risks and benefits of each agent under consideration," the committee said.
The guideline update is based on a systematic review of more than 700 potential randomized controlled trials and meta-analyses published between June 2007 and June 2012. Ultimately, 19 articles on six different chemoprevention agents met the selection criteria of the committee, which was convened by the ASCO Clinical Practice Guidelines Committee. Members were experts – with special expertise in breast cancer – from clinical medicine, public health, clinical research, health services, and related areas such as biostatistics and epidemiology. A patient representative also was appointed to the committee.
In addition to the changes regarding the discussion of tamoxifen and raloxifene, the updated guideline also eliminates a recommendation from the 2009 version calling for a baseline gynecologic examination before initiation of treatment and annually thereafter, and removes mention of treatment with fenretinide, which the committee determined is "no longer relevant for breast cancer chemoprevention."
The committee also addressed ongoing challenges with respect to minimizing health disparities, which the committee said "are an important consideration in reducing breast cancer risk."
"Members of racial and ethnic minorities, in general, tend to be diagnosed with cancer at more advanced stages and have worse outcomes ... Awareness of these disparities in quality of care and access to care should be considered in the context of this clinical practice guideline. Health care providers should strive to deliver the highest level of cancer care to all patients," the guideline states.
As for future directions, the committee stressed a need for addressing "the many unresolved issues related to the poor uptake of breast cancer chemoprevention agents in women who are at increased risk of breast cancer."
An estimated 2 million or more women could benefit from breast cancer chemoprevention, yet the agents recommended in this guideline are used infrequently for breast cancer risk reduction, the committee said, noting a need for the design of effective tools and approaches to educate providers and identify women at increased risk, and for efficacious interventions and greater understanding of the disparities and barriers that exist regarding use of chemoprevention strategies.
"Not every woman should use these preventive agents, but we believe women who are at increased risk for breast cancer should be given the option, because in some cases the magnitude of the risk reduction is large. For some women, these therapies can reduce the risk of breast cancer by up to 50%," Dr. Visvanathan said in a press statement.
A data supplement with tables and figures, and clinical tools and resources to help clinicians implement this guideline is available at ASCO’s website.
Dr. Visvanathan reported having no disclosures. Other Update Committee members reported serving as consultants and/or receiving honoraria or research funding from Novartis, Pfizer, Bayer, Champions Biotechnology, and/or AstraZeneca. One author also reported owning Novartis stock.

Members were experts – with special expertise in breast cancer – from clinical medicine, public health, clinical research, health services, and related areas such as biostatistics and epidemiology. A patient representative also was appointed to the committee.
In addition to the changes regarding the discussion of tamoxifen and raloxifene, the updated guideline also eliminates a recommendation from the 2009 version calling for a baseline gynecologic examination before initiation of treatment and annually thereafter, and removes mention of treatment with fenretinide, which the committee determined is "no longer relevant for breast cancer chemoprevention."
The committee also addressed ongoing challenges with respect to minimizing health disparities, which the committee said "are an important consideration in reducing breast cancer risk."
"Members of racial and ethnic minorities, in general, tend to be diagnosed with cancer at more advanced stages and have worse outcomes ... Awareness of these disparities in quality of care and access to care should be considered in the context of this clinical practice guideline. Health care providers should strive to deliver the highest level of cancer care to all patients," the guideline states.
As for future directions, the committee stressed a need for addressing "the many unresolved issues related to the poor uptake of breast cancer chemoprevention agents in women who are at increased risk of breast cancer."
An estimated 2 million or more women could benefit from breast cancer chemoprevention, yet the agents recommended in this guideline are used infrequently for breast cancer risk reduction, the committee said, noting a need for the design of effective tools and approaches to educate providers and identify women at increased risk, and for efficacious interventions and greater understanding of the disparities and barriers that exist regarding use of chemoprevention strategies.
"Not every woman should use these preventive agents, but we believe women who are at increased risk for breast cancer should be given the option, because in some cases the magnitude of the risk reduction is large. For some women, these therapies can reduce the risk of breast cancer by up to 50%," Dr. Visvanathan said in a press statement.
A data supplement with tables and figures, and clinical tools and resources to help clinicians implement this guideline is available at ASCO’s website.
Dr. Visvanathan reported having no disclosures. Other Update Committee members reported serving as consultants and/or receiving honoraria or research funding from Novartis, Pfizer, Bayer, Champions Biotechnology, and/or AstraZeneca. One author also reported owning Novartis stock.
Tamoxifen for the prevention of breast cancer should be discussed with women aged 35 years or older who are at increased risk for the disease, according to an updated clinical practice guideline from the American Society of Clinical Oncology.
The use of raloxifene and exemestane should be discussed with postmenopausal women who are at increased risk for the disease, according to the update – the third since the guideline, entitled "Use of Pharmacologic Interventions for Breast Cancer Risk Reduction," was first published in 1999, and the first since 2009 (J. Clin. Onco. 2009;27:3235-58).
The new update includes stronger wording regarding discussion about the selective estrogen-receptor modulators tamoxifen and raloxifene, compared with the 2009 version, which stated that tamoxifen and raloxifene "may be offered" to women at increased risk.
"The committee felt that a stronger statement recommending the use of tamoxifen and raloxifene was needed given the weight of evidence from phase III randomized trials demonstrating a reduction in breast cancer risk for both tamoxifen and raloxifene," Update Committee cochair, Dr. Kala Visvanathan of Johns Hopkins Medical Institutions, Baltimore, and the other committee members reported (J. Clin. Oncol. 2013 July 8 [doi 10.1200/JCO.2013.49.3122]).
The guideline recommendations, which were published online on July 8 in the Journal of Clinical Oncology, and which are limited to pharmacologic interventions, specifically call for discussing with patients the options of:
• Oral tamoxifen treatment at a dose of 20 mg daily for 5 years to reduce the risk of estrogen receptor- (ER) positive invasive breast cancer in both pre- and postmenopausal women aged at least 35 years who are at increased risk of breast cancer or who have lobular carcinoma in situ (LCIS). Increased risk is defined as a 5-year projected absolute risk of 1.66% or greater according to the National Cancer Institute Breast Cancer Risk Assessment Tool or an equivalent measure. This "strong, evidence-based recommendation" is based on data from multiple randomized, controlled trials showing that the risk reduction benefit of this treatment continues for at least 10 years in these patients.
• Oral raloxifene treatment at a dose of 60 mg daily for 5 years to reduce the risk of ER-positive invasive breast cancer in postmenopausal women aged at least 35 years who are at increased risk or who have LCIS. This "strong, evidence-based recommendation" also is based on data from multiple randomized, controlled trials.
• Oral exemestane at a dose of 25 mg daily for 5 years as an alternative to tamoxifen or raloxifene to reduce the risk of ER-positive invasive breast cancer in postmenopausal women aged at least 35 years who are at increased risk of breast cancer or who have LCIS. This "moderate, evidence-based recommendation" is based on encouraging evidence from a single randomized, controlled trial of the aromatase inhibitor, which is approved for the treatment of breast cancer but not for breast cancer prevention.
Tamoxifen and raloxifene are not recommended for use in women with a history of deep vein thrombosis, pulmonary embolus, stroke, or transient ischemic attack, nor are they recommended during prolonged immobilization. Tamoxifen is not recommended in women who are pregnant or who may become pregnant or in women who are nursing, and it should not be used in combination with hormone therapy. Exemestane should not be used in premenopausal women, according to the guideline.
"Discussions with patient and health care providers should include both the risks and benefits of each agent under consideration," the committee said.

Early, late solid food exposures up diabetes risk
Babies who are first exposed to solid food before the age of 4 months or at age 6 months or older are significantly more likely to develop type 1 diabetes mellitus than those with a first exposure at 4-5 months of age, findings from a longitudinal observational study have shown.
Of 1,835 children at increased genetic risk for type 1 diabetes mellitus (T1DM) who were included in the Diabetes Autoimmunity Study in the Young (DAISY), 53 developed the disease during follow-up. After adjustment for the human leukocyte antigen (HLA)-DR genotype, a first-degree relative with T1DM, maternal education, and delivery type, both the early and late first solid food exposures significantly predicted T1DM development (adjusted hazard ratios, 1.91 and 3.02, respectively), Brittni Frederiksen of the University of Colorado, Aurora, and her colleagues reported online on July 8 in JAMA Pediatrics.
Specifically, babies with early exposure to fruit and those with late exposure to rice/oat (non–gluten-containing foods) were at increased risk of T1DM development (HR, 2.23 and 2.88, respectively), the investigators found (JAMA Pediatr. July [doi:10.1001/jamapediatrics.2013.317]).
Of note, babies who were still breastfeeding at the time of introduction to wheat/barley (gluten-containing food) had a significantly reduced risk of T1DM development (HR, 0.47), suggesting that breastfeeding confers some protection against the disease, they said.
The timing of the introduction of vegetables and meat did not predict T1DM in the DAISY cohort.
DAISY participants included two groups of children at increased genetic risk for developing T1DM – a group found to have diabetes-susceptibility alleles in the HLA region on cord blood screening, and a group of unaffected children with a first-degree relative with T1DM. Children included in the current analysis were those followed from birth, who completed clinic visits at 9, 15, and 24 months, and annually thereafter.
The findings, which support those from an earlier DAISY report demonstrating "a window of time for introduction of cereals, 4-6 months, outside of which the risk for development of islet autoimmunity (preclinical T1DM) increased." are important given the increasing worldwide incidence of T1DM. That increase is most rapid among children younger than age 5 years, the investigators noted.
As for the mechanisms of associations between early and late food exposures and T1DM development, the risk predicted by early exposure "might suggest a mechanism involving an abnormal immune response to solid food antigens in an immature gut immune system in susceptible individuals," and the increased risk predicted by late exposures "may be related to the larger amounts given at initial exposure to older children," the investigators said.
Also, the late introduction of solid foods, when breast milk no longer meets energy and nutrient needs, could lead to nutrient deficiencies that could increase T1DM risk. Similarly, late solid food exposures may be related to the cessation of breastfeeding before solid food introduction, resulting in the loss of the protective effects of breast milk in that setting, they suggested.
Although the findings require confirmation in a larger cohort, they provide some guidance for the introduction of solid foods.
"While much of the focus of infant diet and T1DM research has been on the timing of the introduction of a single antigen (i.e., milk or gluten), our data suggest multiple foods/antigens play a role and that there is a complex relationship between the timing and type of infant food exposures and T1DM risk. In summary, there appears to be a safe window in which to introduce solid foods between 4 and 5 months of age; solid foods should be introduced while continuing to breastfeed to minimize T1DM risk in genetically susceptible children," the investigators concluded.
This study was supported by a National Institutes of Health grant and a Diabetes Endocrine Research Center Clinical Investigation and Bioinformatics Core grant. The authors reported having no relevant financial disclosures.

CD30 expression in EBV+ DLBCL confers poor prognosis
Epstein-Barr virus-positive diffuse large B-cell lymphoma, or EBV+ DLBCL, represents only a small proportion of DLBCLs, and has an activated B-cell type immunophenotype and a unique gene expression profile and genetic signature that distinguish the neoplasm from EBV-negative DLBCL, according to a report from the International DLBCL Rituximab-CHOP Consortium Program Study.
Further, CD30 expression is more common in EBV+ DLBCL than in EBV-negative DLBCL and confers an adverse outcome, Dr. Ken He Young reported at the annual International Conference on Malignant Lymphoma in Lugano, Switzerland.
The findings are based on a study of 451 HIV-negative de novo DLBCL patients who had tissue microarrays from primary biopsy specimens available. All were uniformly treated with rituximab plus chemotherapy with cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP), said Dr. Young of the department of hematopathology at the University of Texas MD Anderson Cancer Center, Houston (Hematol. Oncol. 2013;31[(Suppl 1]:96-150[abstract 9]).
Of the 451 patients, 27 (6%) had positive EBV-encoded RNA (EBER) test results, defined as reactivity in more than 10% of malignant cells. The median age of the EBV+ and EBV- patients was similar at 61 and 64 years, respectively, as were the presenting clinical characteristics, Dr. Young noted.
However, an activated B-cell type signature occurred in 70% of EBV+ patients, compared with 48% or 49% (based on gene expression profiling and immunohistochemistry using the Visco-Young algorithm, respectively) in the EBV- patients, and CD30 expression occurred in 48% of EBV+ patients, compared with 15% of EBV- patients, he said.
No difference was seen in the expression of BCL2, MYC or both proteins between the EBV+ and EBV- groups, but the EBV+ patients had no detrimental TP53 mutation and only 18% presented rearrangements involving BCL2, C-MYC, or BCL6 genes.
Five-year overall survival appeared inferior in the EBV+ DLBCL patients at 50%, compared with 62% for the EBV- DLBCL patients, even after stratification by age, but the difference between the groups did not reach statistical significance. The same was true for progression-free survival, Dr. Young noted.
Among EBV+ DLBCL patients with CD30 expression, however, the prognosis was dismal, with median overall and progression-free survival of 37% and 35%, respectively, compared with 74% and 56%, respectively, in those with CD30 negative EBV+ DLBCL. These differences were statistically significant, Dr. Young said, adding that gene expression profiling revealed a unique expression signature in EBV+ DLBCL with NF-kB pathway activation.
In a separate report from the International DLBCL Rituximab-CHOP Consortium Program Study published online in May in Blood, Dr. Young and his colleagues explained that EBV+ DLBCL of the elderly, which was initially described 10 years ago, is a provisional entity within the World Health Organization classification system, and is defined as "an EBV-positive monoclonal large B-cell proliferation that occurs in patients greater than 50 years of age and in whom there is no known immunodeficiency or history of lymphoma," (2013;121: 2715-24 [doi:10.1182/blood-2012-10-461848]).
"It is hoped that the improved understanding of these tumors will lead to development of novel therapeutic approaches, enhance the effective clinical trials, and improve the prognosis," the investigators said.

Ibrutinib shows promise for CLL del 17p
Single-agent ibrutinib therapy was highly effective and well tolerated in 29 patients with chronic lymphocytic leukemia and deletion of part of the short arm of chromosome 17 (del 17p) who were part of a phase II study.
Treatment with the investigational selective Bruton’s tyrosine kinase inhibitor was associated with rapid control of disease in the nodes, spleen, marrow, and blood in both treatment-naive and relapsed/refractory patients, Dr. Adrian Wiestner reported at the annual International Conference on Malignant Lymphoma in Lugano, Switzerland.
These findings are notable because patients with chronic lymphocytic leukemia (CLL) and del 17p typically have poor progression-free and overall survival when treated with standard chemoimmunotherapy, Dr. Wiestner said, adding that the potential role of ibrutinib for the treatment of these difficult-to-treat patients will be further investigated.
At a median follow-up of 9 months, 88% of 25 evaluable patients had a nodal response with a median 70% reduction in lymph node size, 48% had a partial response by International Workshop on CLL (IWCLL) criteria, and 40% had a partial response with lymphocytosis. One patient had progressive disease, said Dr. Wiestner of the National Heart, Lung, and Blood Institute, National Institutes of Health.
Of 15 treatment-naïve patients aged 33-82 years, 82% achieved a nodal response, and of 14 relapsed/refractory patients aged 56-79 years, 93% achieved a nodal response. The estimated 12-month event-free survival among the patients, who were the first in the study to reach 9-month median follow-up, was 90%, Dr. Wiestner said.
Also, 22 evaluable patients had a median 46% reduction in splenomegaly (median volume reduction of 446 mL), and tumor burden in bone marrow biopsies of 23 patients decreased by a median of 76% as assessed by immunohistochemistry for CD79a.
The percentage of tumor cells with del 17p decreased by a median of 55% in 15 patients, remained unchanged in 1 patient, and increased in 3 patients.
Treatment-naive patients included adults aged 33-82 years, and relapsed/refractory patients were adults aged 56-79 years. All were treated with 420 mg of oral ibrutinib daily until disease progression; treatment response was assessed every 6 months.
Ibrutinib, which has been granted multiple Breakthrough Therapy designations by the Food and Drug Administration – including a recent designation for the treatment of CLL or small lymphocytic lymphoma with del 17p – was well tolerated; 14% of patients experienced grade 3 or higher nonhematologic toxicities. Two deaths occurred among patients in the study, but were not deemed treatment related.
This study was supported by the Intramural Research Program of the National Heart, Lung, and Blood Institute.
Single-agent ibrutinib therapy was highly effective and well tolerated in 29 patients with chronic lymphocytic leukemia and deletion of part of the short arm of chromosome 17 (del 17p) who were part of a phase II study.
Treatment with the investigational selective Bruton’s tyrosine kinase inhibitor was associated with rapid control of disease in the nodes, spleen, marrow, and blood in both treatment-naive and relapsed/refractory patients, Dr. Adrian Wiestner reported at the annual International Conference on Malignant Lymphoma in Lugano, Switzerland.
These findings are notable because patients with chronic lymphocytic leukemia (CLL) and del 17p typically have poor progression-free and overall survival when treated with standard chemoimmunotherapy, Dr. Wiestner said, adding that the potential role of ibrutinib for the treatment of these difficult-to-treat patients will be further investigated.
At a median follow-up of 9 months, 88% of 25 evaluable patients had a nodal response with a median 70% reduction in lymph node size, 48% had a partial response by International Workshop on CLL (IWCLL) criteria, and 40% had a partial response with lymphocytosis. One patient had progressive disease, said Dr. Wiestner of the National Heart, Lung, and Blood Institute, National Institutes of Health.
Of 15 treatment-naïve patients aged 33-82 years, 82% achieved a nodal response, and of 14 relapsed/refractory patients aged 56-79 years, 93% achieved a nodal response. The estimated 12-month event-free survival among the patients, who were the first in the study to reach 9-month median follow-up, was 90%, Dr. Wiestner said.
Also, 22 evaluable patients had a median 46% reduction in splenomegaly (median volume reduction of 446 mL), and tumor burden in bone marrow biopsies of 23 patients decreased by a median of 76% as assessed by immunohistochemistry for CD79a.

Dose reduction bests maintenance therapy for first-episode psychosis
Recovery and functional remission rates at 7 years following first-episode psychosis in patients treated using a dose-reduction/discontinuation strategy during the early stages of remission were more than double those in patients who received maintenance therapy in a randomized controlled trial.
The recovery rate was 40.4% in 52 patients who were randomly assigned to the dose reduction/discontinuation (DR) strategy after experiencing 6 months of remission, compared with 17.6% in 51 patients randomized to receive maintenance therapy for 18 months after 6 months of remission (odds ratio, 3.49). The functional remission rates were 46.2% and 19.6% in the two groups, respectively (OR, 4.62), Dr. Lex Wunderink of Friesland Mental Health Services, Leeuwarden, the Netherlands, and his colleagues reported. The results were published online July 3 in JAMA Psychiatry.
Symptomatic remission, at 69.2% and 66.7% in the groups, respectively, did not differ significantly (JAMA Psychiatry 2013 July 3 [doi: 10.1001/jamapsychiatry.2013.19]).
The findings, which are among the first to demonstrate major advantages of a dose reduction versus maintenance therapy strategy in patients with remission of first-episode psychosis, are also the first to look at long-term outcomes. Earlier studies demonstrated higher relapse rates and no advantages with DR, but those studies had follow-up of no more than 2 years, the investigators noted.
To evaluate the long-term outcome of an early-course DR strategy compared with maintenance therapy, they conducted this 7-year follow-up assessment of 103 out of 128 patients with first-episode psychosis who participated in one of the earlier trials with enrollment, at the start of their first remission, between October 2001 and December 2002.
Of note, time to first relapse during the experimental phase of the trial was about twice as high in the DR group initially, but "the curves then approached each other and came on par at approximately 3 years of follow-up. From then on, the findings were not significantly different," the investigators reported.
"The major issue is, of course, whether these striking results may be attributed to the treatment strategies in the original trial. There were no significant differences in any of the conceivable confounding variables between the two groups. Therefore, it seems likely that the original treatment strategy, be it dose reduction or maintenance therapy, has a profound effect on long-term outcome," they wrote, noting that the differences are largely the result of effects in the domains of functional remission and recovery.
The gains in functional capacity in the DR arm could be associated with the fact that successful discontinuation in the early course of first-episode psychosis was sustained for many years in almost all patients, who, on average, used a lower dose of antipsychotic drugs than did those in the maintenance therapy group.
The psychological impact of having been treated using a dose reduction strategy also might have played a role in the effects on functional capacity, but this was not measured, they said.
"The results of this study lead to the following conclusions: schizophrenia treatment strategy trials should include recovery or functional remission rates as their primary outcome and should also include long-term follow-up for more than 2 years, even up to 7 years or longer," the investigators said. The results "merit replication by other research groups," and underscore a need for also studying other alternative treatment strategies, such as extended-interval dosing strategies, they added.

Rituximab plus chlorambucil extend event-free survival in MALT lymphoma
Patients who have mucosa-associated lymphoid tissue lymphoma and are treated with chlorambucil plus rituximab have better event-free survival and progression-free survival than do comparable patients treated with either drug alone, according to findings from a randomized phase III study.
In the International Extranodal Lymphoma Study Group study (IELSG-19), 5-year event-free survival was 70% in 131 patients treated with the combination therapy, 52% in 130 patients treated with chlorambucil alone, and 51% in 132 patients treated with rituximab alone. Progression-free survival also was significantly improved in the combination therapy arm compared with the two single-agent arms, Dr. Emanuele Zucca reported at the annual International Conference on Malignant Lymphoma in Lugano, Switzerland.
Overall survival at 5 years, however, was similar at about 90% for all three treatment arms, according to Dr. Zucca of the Oncology Institute of Southern Switzerland, Ospedale San Giovanni, Bellinzona.
Hematologic toxicity was more pronounced in the combination therapy arm than in the single-agent arms, but there were no unexpected severe side effects, Dr. Zucca reported.
IELSG-19 is the largest randomized study to date in MALT lymphoma, and is the first to compare combination chlorambucil and rituximab with both agents alone, he said.
The primary lymphoma site was the stomach in 43% of the393 study participants, and 34% had lymph node involvement. The international prognostic index score was low or low-intermediate in 81%. Just 8% of the patients had prior local therapy, Dr. Zucca said.
Study participants were adults with disseminated extranodal marginal zone B-cell lymphoma or localized disease not amenable to local therapy. Those randomized to the chlorambucil therapy arm received 6 mg/m2 of oral chlorambucil daily for 6 weeks, and those who responded or who had stable disease received the same dose daily for 14 consecutive days every 28 days for four cycles. Those in the combination therapy arm received the chlorambucil dosing, plus 375 mg/m2 of rituximab intravenously on days 1, 8, 15, 22, 56, 84, 112, and 140. Those in the rituximab-only group received the same rituximab dosing without chlorambucil.
In a published report of the outcomes in patients enrolled in the first two protocol arms (combination therapy and chlorambucil-only therapy), Dr. Zucca and his colleagues noted that survival rates in patients with MALT lymphoma are typically high. The significant differences in event-free survival have not yet translated into improved overall survival (J. Clin. Oncol 2013 Jan. 7 [doi:10.1200/JCO.2011.40.6272]).
Nonetheless, the findings – among the first to demonstrate the activity of chlorambucil with and without rituximab in MALT lymphoma – suggest the combination is a safe and effective approach that could improve outcomes, Dr. Zucca said.
The findings he presented expand upon the initial published analysis by including data from the rituximab-only arm, which was added following a more-rapid-than-expected initial recruitment into the combination and chlorambucil-only arms.
These findings are of note, because aside from H. pylori eradication for localized gastric disease, no consensus exists on the standard therapy for MALT lymphoma, he said.
Several study authors reported serving as consultants for or receiving honoraria from Roche International, which sponsored the IELSG-19 study.
