TOPLINE:

In patients with pulmonary oligometastases from colorectal cancer (CRC), both stereotactic body radiotherapy (SBRT) and surgery led to similar overall survival rates at 5 years. However, those who received surgery had significantly better progression-free and disease-free survival rates, as well as a longer time to intrathoracic progression.
 

METHODOLOGY:

• SBRT has been shown to provide effective local control and improve short-term survival for patients with pulmonary oligometastases from CRC and has become an alternative for these patients who are ineligible or reluctant to undergo surgery. It’s unclear, however, whether SBRT should be prioritized over surgery in patients with CRC pulmonary metastases, largely because of a lack of prospective data.
• In the current analysis, researchers compared outcomes among 335 patients (median age, 61 years) with lung metastases from CRC who underwent surgery or SBRT, using data from the Peking University Cancer Hospital and Institute between March 2011 and September 2022.
• A total of 251 patients were included in the final analysis after propensity score matching, 173 (68.9%) underwent surgery and 78 (31.1%) received SBRT. The median follow-up was 61.6 months in the surgery group and 54.4 months in the SBRT group.
• The study outcomes were freedom from intrathoracic progression, progression-free survival, and overall survival.

TAKEAWAY:

• At 5 years, rates of freedom from intrathoracic progression were more than twofold higher in the surgery group than in the SBRT group (53% vs 23.4%; hazard ratio [HR], 0.46; P < .001). Progression-free survival rates were also more than twofold higher in the surgery group vs the SBRT group (43.8% vs 18.5%; HR, 0.47; P < .001), respectively. In the SBRT group, a higher percentage of patients had a disease-free interval of less than 12 months compared with the surgery group, with rates of 48.7% and 32.9%, respectively (P = 0.025). 
• Overall survival, however, was not significantly different between the two groups at 5 years (72.5% in the surgery group vs 63.7% in the SBRT group; P = .260). The number of pulmonary metastases (HR, 1.87; 95% CI, 1.11-3.14, P = .019 and tumor size (HR, 1.03; 95% CI, 1.00-1.05, P = .023) were significant prognostic factors for overall survival.
• Local recurrence was more prevalent after SBRT (33.3%) than surgery (16.9%), while new intrathoracic tumors occurred more frequently after surgery than SBRT (71.8% vs 43.1%). Repeated local treatments were common among patients with intrathoracic progression, which might have contributed to favorable survival outcomes in both groups.
• Both treatments were well-tolerated with no treatment-related mortality or grade ≥ 3 toxicities. In the surgery group, 14 patients experienced complications, including atrial fibrillation (n = 4) and prolonged air leaks (n = 7). In the SBRT group, radiation pneumonitis was the most common adverse event (n = 21).

IN PRACTICE:

SBRT yielded overall survival benefits similar to surgery despite a “higher likelihood of prior extrapulmonary metastases, a shorter disease-free interval, and a greater number of metastatic lesions,” the authors wrote. Still, SBRT should be regarded as an “effective alternative in cases in which surgical intervention is either unviable or declined by the patient,” the authors concluded.
 

SOURCE:

The study was co-led by Yaqi Wang and Xin Dong, Peking University Cancer Hospital & Institute, Beijing, China, and was published online in the International Journal of Radiation Oncology, Biology, Physics.
 

LIMITATIONS:

This single-center retrospective study had an inherent selection bias. The lack of balanced sample sizes of the surgery and SBRT groups might have affected the robustness of the statistical analyses. Detailed data on adverse events were not available.
 

DISCLOSURES:

The study was supported by grants from the National Natural Science Foundation of China, Beijing Natural Science Foundation, and Beijing Municipal Administration of Hospital’s Ascent Plan. The authors did not declare any conflicts of interest.

Each year in the United States, approximately 1.7 million Americans are diagnosed with a potentially lethal malignancy. Typical therapies of choice include surgery, radiation, and occasionally, toxic chemotherapy (chemo) — approaches that eliminate the cancer in about 1,000,000 of these cases. The remaining 700,000 or so often proceed to chemotherapy either immediately or upon cancer recurrence, spread, or newly recognized metastases. “Cures” after that point are rare.

I’m speaking in generalities, understanding that each cancer and each patient is unique.
 

Chemotherapy

Chemotherapy alone can cure a small number of cancer types. When added to radiation or surgery, chemotherapy can help to cure a wider range of cancer types. As an add-on, chemotherapy can extend the length and quality of life for many patients with cancer. Since chemotherapy is by definition “toxic,” it can also shorten the duration or harm the quality of life and provide false hope. The Table summarizes what chemotherapy can and cannot achieve in selected cancer types.

• Lack of response (the tumor failed to shrink).
• Progression (the cancer may have grown or spread further).
• Adverse side effects were too severe to continue.

The drugs used in second-line chemo will typically be different from those used in first line, sometimes because cancer cells can develop resistance to chemotherapy drugs over time. Moreover, the goal of second-line chemo may differ from that of first-line therapy. Rather than chiefly aiming for a cure, second-line treatment might focus on slowing cancer growth, managing symptoms, or improving quality of life. Unfortunately, not every type of cancer has a readily available second-line option.

Third-line treatment. Third-line options come into play when both the initial course of chemo (first line) and the subsequent treatment (second line) have failed to achieve remission or control the cancer’s spread. Owing to the progressive nature of advanced cancers, patients might not be eligible or healthy enough for third-line therapy. Depending on cancer type, the patient’s general health, and response to previous treatments, third-line options could include:

• New or different chemotherapy drugs compared with prior lines.
• Surgery to debulk the tumor.
• Radiation for symptom control.
• Targeted therapy: drugs designed to target specific vulnerabilities in cancer cells.
• Immunotherapy: agents that help the body’s immune system fight cancer cells.
• Clinical trials testing new or investigational treatments, which may be applicable at any time, depending on the questions being addressed.

The goals of third-line therapy may shift from aiming for a cure to managing symptoms, improving quality of life, and potentially slowing cancer growth. The decision to pursue third-line therapy involves careful consideration by the doctor and patient, weighing the potential benefits and risks of treatment considering the individual’s overall health and specific situation.

It’s important to have realistic expectations about the potential outcomes of third-line therapy. Although remission may be unlikely, third-line therapy can still play a role in managing the disease.

Navigating advanced cancer treatment is very complex. The patient and physician must together consider detailed explanations and clarifications to set expectations and make informed decisions about care.
 

Interventions to Consider Earlier

In traditional clinical oncology practice, other interventions are possible, but these may not be offered until treatment has reached the third line:

• Molecular testing.
• Palliation.
• Clinical trials.
• Innovative testing to guide targeted therapy by ascertaining which agents are most likely (or not likely at all) to be effective.

I would argue that the patient’s interests are better served by considering and offering these other interventions much earlier, even before starting first-line chemotherapy.

Molecular testing. The best time for molecular testing of a new malignant tumor is typically at the time of diagnosis. Here’s why:

• Molecular testing helps identify specific genetic mutations in the cancer cells. This information can be crucial for selecting targeted therapies that are most effective against those specific mutations. Early detection allows for the most treatment options. For example, for non–small cell lung cancer, early is best because treatment and outcomes may well be changed by test results.
• Knowing the tumor’s molecular makeup can help determine whether a patient qualifies for clinical trials of new drugs designed for specific mutations.
• Some molecular markers can offer information about the tumor’s aggressiveness and potential for metastasis so that prognosis can be informed.

Molecular testing can be a valuable tool throughout a cancer patient’s journey. With genetically diverse tumors, the initial biopsy might not capture the full picture. Molecular testing of circulating tumor DNA can be used to monitor a patient’s response to treatment and detect potential mutations that might arise during treatment resistance. Retesting after metastasis can provide additional information that can aid in treatment decisions.

Palliative care. The ideal time to discuss palliative care with a patient with cancer is early in the diagnosis and treatment process. Palliative care is not the same as hospice care; it isn’t just about end-of-life. Palliative care focuses on improving a patient’s quality of life throughout cancer treatment. Palliative care specialists can address a wide range of symptoms a patient might experience from cancer or its treatment, including pain, fatigue, nausea, and anxiety.

Early discussions allow for a more comprehensive care plan. Open communication about all treatment options, including palliative care, empowers patients to make informed decisions about their care goals and preferences.

Specific situations where discussing palliative care might be appropriate are:

• Soon after a cancer diagnosis.
• If the patient experiences significant side effects from cancer treatment.
• When considering different treatment options, palliative care can complement those treatments.
• In advanced stages of cancer, to focus on comfort and quality of life.

Clinical trials. Participation in a clinical trial to explore new or investigational treatments should always be considered.

In theory, clinical trials should be an option at any time in the patient’s course. But the organized clinical trial experience may not be available or appropriate. Then, the individual becomes a de facto “clinical trial with an n of 1.” Read this brief open-access blog post at Cancer Commons to learn more about that circumstance.

Innovative testing. The best choice of chemotherapeutic or targeted therapies is often unclear. The clinician is likely to follow published guidelines, often from the National Comprehensive Cancer Network.

These are evidence based and driven by consensus of experts. But guideline-recommended therapy is not always effective, and weeks or months can pass before this ineffectiveness becomes apparent. Thus, many researchers and companies are seeking methods of testing each patient’s specific cancer to determine in advance, or very quickly, whether a particular drug is likely to be effective.

It’s important to have realistic expectations about the potential outcomes of third-line therapy. Although remission may be unlikely, third-line therapy can still play a role in managing the disease.

Navigating advanced cancer treatment is very complex. The patient and physician must together consider detailed explanations and clarifications to set expectations and make informed decisions about care.
 

Interventions to Consider Earlier

In traditional clinical oncology practice, other interventions are possible, but these may not be offered until treatment has reached the third line:

• Molecular testing.
• Palliation.
• Clinical trials.
• Innovative testing to guide targeted therapy by ascertaining which agents are most likely (or not likely at all) to be effective.

I would argue that the patient’s interests are better served by considering and offering these other interventions much earlier, even before starting first-line chemotherapy.

Molecular testing. The best time for molecular testing of a new malignant tumor is typically at the time of diagnosis. Here’s why:

• Molecular testing helps identify specific genetic mutations in the cancer cells. This information can be crucial for selecting targeted therapies that are most effective against those specific mutations. Early detection allows for the most treatment options. For example, for non–small cell lung cancer, early is best because treatment and outcomes may well be changed by test results.
• Knowing the tumor’s molecular makeup can help determine whether a patient qualifies for clinical trials of new drugs designed for specific mutations.
• Some molecular markers can offer information about the tumor’s aggressiveness and potential for metastasis so that prognosis can be informed.

Molecular testing can be a valuable tool throughout a cancer patient’s journey. With genetically diverse tumors, the initial biopsy might not capture the full picture. Molecular testing of circulating tumor DNA can be used to monitor a patient’s response to treatment and detect potential mutations that might arise during treatment resistance. Retesting after metastasis can provide additional information that can aid in treatment decisions.

Palliative care. The ideal time to discuss palliative care with a patient with cancer is early in the diagnosis and treatment process. Palliative care is not the same as hospice care; it isn’t just about end-of-life. Palliative care focuses on improving a patient’s quality of life throughout cancer treatment. Palliative care specialists can address a wide range of symptoms a patient might experience from cancer or its treatment, including pain, fatigue, nausea, and anxiety.

Early discussions allow for a more comprehensive care plan. Open communication about all treatment options, including palliative care, empowers patients to make informed decisions about their care goals and preferences.

Specific situations where discussing palliative care might be appropriate are:

• Soon after a cancer diagnosis.
• If the patient experiences significant side effects from cancer treatment.
• When considering different treatment options, palliative care can complement those treatments.
• In advanced stages of cancer, to focus on comfort and quality of life.

Clinical trials. Participation in a clinical trial to explore new or investigational treatments should always be considered.

In theory, clinical trials should be an option at any time in the patient’s course. But the organized clinical trial experience may not be available or appropriate. Then, the individual becomes a de facto “clinical trial with an n of 1.” Read this brief open-access blog post at Cancer Commons to learn more about that circumstance.

Innovative testing. The best choice of chemotherapeutic or targeted therapies is often unclear. The clinician is likely to follow published guidelines, often from the National Comprehensive Cancer Network.

These are evidence based and driven by consensus of experts. But guideline-recommended therapy is not always effective, and weeks or months can pass before this ineffectiveness becomes apparent. Thus, many researchers and companies are seeking methods of testing each patient’s specific cancer to determine in advance, or very quickly, whether a particular drug is likely to be effective.

The US Food and Drug Administration (FDA) has approved lazertinib (Lazcluze) in combination with amivantamab-vmjw (Rybrevant) for upfront treatment of adults with locally advanced or metastatic non–small-cell lung cancer (NSCLC) who have EGFR exon 19 deletions or exon 21 L858R substitution mutations as detected by an FDA-approved test. 

This marks the first approval for lazertinib. Amivantamab was initially approved by the FDA in 2021 and carries a few indications for locally advanced or metastatic NSCLC. Both drugs are manufactured by Janssen Biotech Inc.

“Patients will now have the option of a potential new first-line standard of care with significant clinical benefits over osimertinib,” study investigator Alexander Spira, MD, PhD, director, Virginia Cancer Specialists Research Institute, said in a news release from Johnson & Johnson . 

Lazertinib is an oral, highly selective, third-generation EGFR tyrosine kinase inhibitor that can penetrate the brain and amivantamab is a bispecific antibody targeting EGFR and MET.

The approval was based on results from the phase 3 MARIPOSA trial, which showed that the combination reduced the risk of disease progression or death by 30% compared with osimertinib.

The MARIPOSA trial randomly allocated 1074 patients with exon 19 deletion or exon 21 L858R substitution mutation-positive locally advanced or metastatic NSCLC and no prior systemic therapy for advanced disease to amivantamab plus lazertinib, osimertinib alone, or lazertinib alone.

Lazertinib plus amivantamab demonstrated a statistically significant improvement in progression-free survival compared with osimertinib (hazard ratio, 0.70; P < .001). Median progression-free survival was 23.7 months with the combination vs 16.6 months osimertinib alone and 18.5 months with lazertinib alone.

The median duration of response was 9 months longer with the combination compared with osimertinib (25.8 months vs 16.7 months).

The most common adverse reactions (≥ 20%) were rash, nail toxicity, infusion-related reactions (amivantamab), musculoskeletal pain, edema, stomatitis, venous thromboembolism, paresthesia, fatigue, diarrhea, constipation, COVID-19, hemorrhage, dry skin, decreased appetite, pruritus, nausea, and ocular toxicity. 

“A serious safety signal of venous thromboembolic events was observed with lazertinib in combination with amivantamab and prophylactic anticoagulation should be administered for the first four months of therapy,” the FDA noted in a statement announcing the approval.

Results from MARIPOSA were first presented at the European Society for Medical Oncology 2023 Congress and published in The New England Journal of Medicine in June. Longer-term follow-up data from MARIPOSA will be presented at the International Association for the Study of Lung Cancer 2024 World Congress on Lung Cancer in September.

Childhood cancers represent a diverse group of neoplasms, and thanks to advances in treatment, survival rates have improved significantly. Today, more than 80%-85% of children diagnosed with cancer in developed countries survive into adulthood.

This increase in survival has brought new challenges, however. Compared with the general population, childhood cancer survivors (CCS) are at a notably higher risk for early mortality, developing secondary cancers, and experiencing various long-term clinical and psychosocial issues stemming from their disease or its treatment.

Long-term follow-up care for CCS is a complex and evolving field. Despite ongoing efforts to establish global and national guidelines, current evidence indicates that the care and management of these patients remain suboptimal.

Sexual dysfunction is a common and significant late effect among CCS. The disruptions caused by cancer and its treatment can interfere with normal physiological and psychological development, leading to issues with sexual function. This aspect of health is critical as it influences not just physical well-being but also psychosocial, developmental, and emotional health.
 

Characteristics and Mechanisms

Sexual functioning encompasses the physiological and psychological aspects of sexual behavior, including desire, arousal, orgasm, sexual pleasure, and overall satisfaction.

As CCS reach adolescence or adulthood, they often face sexual and reproductive issues, particularly as they enter romantic relationships.

Sexual functioning is a complex process that relies on the interaction of various factors, including physiological health, psychosexual development, romantic relationships, body image, and desire.

Despite its importance, the impact of childhood cancer on sexual function is often overlooked, even though cancer and its treatments can have lifelong effects. 
 

Sexual Function in CCS

A recent review aimed to summarize the existing research on sexual function among CCS, highlighting assessment tools, key stages of psychosexual development, common sexual problems, and the prevalence of sexual dysfunction.

The review study included 22 studies published between 2000 and 2022, comprising two qualitative, six cohort, and 14 cross-sectional studies.

Most CCS reached all key stages of psychosexual development at an average age of 29.8 years. Although some milestones were achieved later than is typical, many survivors felt they reached these stages at the appropriate time. Sexual initiation was less common among those who had undergone intensive neurotoxic treatments, such as those diagnosed with brain tumors or leukemia in childhood.

In a cross-sectional study of CCS aged 17-39 years, about one third had never engaged in sexual intercourse, 41.4% reported never experiencing sexual attraction, 44.8% were dissatisfied with their sex lives, and many rarely felt sexually attractive to others. Another study found that common issues among CCS included a lack of interest in sex (30%), difficulty enjoying sex (24%), and difficulty becoming aroused (23%). However, comparing and analyzing these problems was challenging due to the lack of standardized assessment criteria.

The prevalence of sexual dysfunction among CCS ranged from 12.3% to 46.5%. For males, the prevalence ranged from 12.3% to 54.0%, while for females, it ranged from 19.9% to 57.0%.
 

Factors Influencing Sexual Function

The review identified the following four categories of factors influencing sexual function in CCS: Demographic, treatment-related, psychological, and physiological.

Demographic factors: Gender, age, education level, relationship status, income level, and race all play roles in sexual function.

Female survivors reported more severe sexual dysfunction and poorer sexual health than did male survivors. Age at cancer diagnosis, age at evaluation, and the time since diagnosis were closely linked to sexual experiences. Patients diagnosed with cancer during childhood tended to report better sexual function than those diagnosed during adolescence.

Treatment-related factors: The type of cancer and intensity of treatment, along with surgical history, were significant factors. Surgeries involving the spinal cord or sympathetic nerves, as well as a history of prostate or pelvic surgery, were strongly associated with erectile dysfunction in men. In women, pelvic surgeries and treatments to the pelvic area were commonly linked to sexual dysfunction.

The association between treatment intensity and sexual function was noted across several studies, although the results were not always consistent. For example, testicular radiation above 10 Gy was positively correlated with sexual dysfunction. Women who underwent more intensive treatments were more likely to report issues in multiple areas of sexual function, while men in this group were less likely to have children.

Among female CCS, certain types of cancer, such as germ cell tumors, renal tumors, and leukemia, present a higher risk for sexual dysfunction. Women who had CNS tumors in childhood frequently reported problems like difficulty in sexual arousal, low sexual satisfaction, infrequent sexual activity, and fewer sexual partners, compared with survivors of other cancers. Survivors of acute lymphoblastic leukemia and those who underwent hematopoietic stem cell transplantation (HSCT) also showed varying degrees of impaired sexual function, compared with the general population. The HSCT group showed significant testicular damage, including reduced testicular volumes, low testosterone levels, and low sperm counts.

Psychological factors: These factors, such as emotional distress, play a significant role in sexual dysfunction among CCS. Symptoms like anxiety, nervousness during sexual activity, and depression are commonly reported by those with sexual dysfunction. The connection between body image and sexual function is complex. Many CCS with sexual dysfunction express concern about how others, particularly their partners, perceived their altered body image due to cancer and its treatment.

Physiological factors: In male CCS, low serum testosterone levels and low lean muscle mass are linked to an increased risk for sexual dysfunction. Treatments involving alkylating agents or testicular radiation, and surgery or radiotherapy targeting the genitourinary organs or the hypothalamic-pituitary region, can lead to various physiological and endocrine disorders, contributing to sexual dysfunction. Despite these risks, there is a lack of research evaluating sexual function through the lens of the hypothalamic-pituitary-gonadal axis and neuroendocrine pathways.

TOPLINE:

Stereotactic body radiotherapy (SBRT) is a safe treatment option for patients with oligometastatic cancer, with only 0.5% of patients experiencing severe acute toxicities within 6 months, according to a large real-world analysis.

METHODOLOGY:

• Advances in cancer imaging have helped identify more patients with oligometastatic disease. Although the standard treatment approach typically involves systemic therapy such as chemotherapy and immunotherapy, SBRT has increasingly become an option for these patients. However, the toxicities associated with SBRT remain less clear.
• OligoCare, a European, prospective, registry-based, single-arm observational study, aims to provide real-world outcomes among patients with oligometastatic cancer who received SBRT. In this analysis, the researchers evaluated early toxicities among 1468 patients with different primary cancers — non–small cell lung cancer (NSCLC; 19.7%), colorectal cancer (20%), breast cancer (15.5%), and prostate cancer (44.8%).
• The primary outcome was acute toxicities, including new malignancies and deaths, within 6 months of initiating SBRT.
• Overall, 527 (35.9%) patients received concomitant systemic treatment and 828 (56%) had de novo oligometastatic disease.

TAKEAWAY:

• Overall, though, only eight patients (0.5%) experienced acute SBRT-related toxicity of grade 3 and above within 6 months; two events, however, were fatal (pneumonitis and cerebral hemorrhage), and both occurred in patients with NSCLC.
• The other six grade 3 events included one instance of each of the following: empyema, pneumonia, radiation pneumonitis, radiation skin injury, decreased appetite, and bone pain. Two of these events occurred in patients with NSCLC, two in patients with breast cancer, one in patients with colorectal cancer, and one in patients with prostate cancer.
• New primary malignancies were reported in 13 (0.9%) patients, which included bladder cancer (n = 3), nonmelanoma skin cancer (n = 3), and leukemia (n = 1).
• Overall, 43 (2.9%) patients died within 6 months, most from their primary cancer (58.1%).

IN PRACTICE:

Low rates of early acute toxicities reported in this real-world study help confirm the safety of SBRT in the treatment of oligometastases, the authors concluded. However, “some anatomical sites might be associated with an increased risk of even severe or fatal toxicities.”

SOURCE:

The study, led by Filippo Alongi, Advanced Radiation Oncology Department, IRCCS Sacro Cuore Don Calabria Hospital, Cancer Care Center, Negrar di Valpolicella, Italy, and University of Brescia, also in Italy, was published online in Radiotherapy & Oncology .

LIMITATIONS:

Some limitations of the study include the nonrandomized design and potential variability in patient selection criteria, treatment doses, and schedules.

DISCLOSURES:

The study did not receive any funding support. Two authors declared receiving speaker or lecture honoraria or consultation fees from various sources.

• OligoCare, a European, prospective, registry-based, single-arm observational study, aims to provide real-world outcomes among patients with oligometastatic cancer who received SBRT. In this analysis, the researchers evaluated early toxicities among 1468 patients with different primary cancers — non–small cell lung cancer (NSCLC; 19.7%), colorectal cancer (20%), breast cancer (15.5%), and prostate cancer (44.8%).
• The primary outcome was acute toxicities, including new malignancies and deaths, within 6 months of initiating SBRT.
• Overall, 527 (35.9%) patients received concomitant systemic treatment and 828 (56%) had de novo oligometastatic disease.

TAKEAWAY:

• Overall, though, only eight patients (0.5%) experienced acute SBRT-related toxicity of grade 3 and above within 6 months; two events, however, were fatal (pneumonitis and cerebral hemorrhage), and both occurred in patients with NSCLC.
• The other six grade 3 events included one instance of each of the following: empyema, pneumonia, radiation pneumonitis, radiation skin injury, decreased appetite, and bone pain. Two of these events occurred in patients with NSCLC, two in patients with breast cancer, one in patients with colorectal cancer, and one in patients with prostate cancer.
• New primary malignancies were reported in 13 (0.9%) patients, which included bladder cancer (n = 3), nonmelanoma skin cancer (n = 3), and leukemia (n = 1).
• Overall, 43 (2.9%) patients died within 6 months, most from their primary cancer (58.1%).

IN PRACTICE:

Low rates of early acute toxicities reported in this real-world study help confirm the safety of SBRT in the treatment of oligometastases, the authors concluded. However, “some anatomical sites might be associated with an increased risk of even severe or fatal toxicities.”

TOPLINE:

Stereotactic body radiotherapy (SBRT) is a safe treatment option for patients with oligometastatic cancer, with only 0.5% of patients experiencing severe acute toxicities within 6 months, according to a large real-world analysis.

METHODOLOGY:

• Advances in cancer imaging have helped identify more patients with oligometastatic disease. Although the standard treatment approach typically involves systemic therapy such as chemotherapy and immunotherapy, SBRT has increasingly become an option for these patients. However, the toxicities associated with SBRT remain less clear.

An estimated 450,000 US deaths are expected this year from conditions attributed to cigarette smoking. Although the percentage of adults who smoke declined from 21% in 2005 to 11% in 2022, the annual death toll has been stable since 2005 and isn’t expected to decline until 2030, owing to an aging population of current and former smokers.

In 2022, based on a national survey, two thirds of the 28.8 million US adult smokers wanted to quit, and more than half tried quitting on their own or with the help of clinicians, but less than 9% succeeded in kicking the habit. The health benefits of quitting, summarized in a patient education handout from the American Cancer Society, include a lower risk for cancer, diabetes, and cardiovascular disease. Furthermore, the handout states, “quitting smoking can add as much as 10 years to your life, compared to if you continued to smoke.”

For my patients older than age 50 who are lifelong smokers, the qualifier “as much as” can be a sticking point. Although most recognize that continuing to smoke exposes them to greater health risks and are willing to undergo lung cancer screening and receive pneumococcal vaccines, a kind of fatalism frequently sets in. I’ve heard more times than I can recall some version of the declaration, “It’s too late for quitting to make much difference for me.” Many smokers think that once they reach middle age, gains in life expectancy will be too small to be worth the intense effort and multiple failed attempts that are typically required to quit permanently. Until recently, there were few data I could call on to persuade them they were wrong.

In February 2024, Dr. Eo Rin Cho and colleagues pooled data from four national cohort studies (United States, United Kingdom, Norway, and Canada) to calculate mortality differences among current, former, and never smokers aged 20-79 years. Compared with never smokers, lifelong smokers died an average of 12-13 years earlier. However, quitting before age 50 nearly eliminated the excess mortality associated with smoking, and in the 50- to 59-year-old age group, cessation eventually reduced excess mortality by 92%-95%. Better yet, more than half of the benefits occurred within the first 3 years after cessation.

At first glance, these estimates may seem too good to be true. A few months later, though, a different research group, using data from a large cancer prevention study and 2018 US population census and mortality rates, largely confirmed their findings. Dr. Thuy Le and colleagues found that quitting at age 35, 45, 55, 65, or 75 years resulted in average life gains of 8, 5.6, 3.5, 1.7, and 0.7 years, respectively, relative to continuing to smoke. Because no patient is average, the analysis also presented some helpful probabilities. For example, a smoker who quits at age 65 has about a 1 in 4 chance of gaining at least 1 full year of life and a 1 in 6 chance of gaining at least 4 years. In other words, from a life expectancy perspective alone, it’s almost never too late to quit smoking.

The Food and Drug Administration (FDA) has approved durvalumab (Imfinzi; AstraZeneca) both before and after surgery in patients with resectable non–small cell lung cancer (NSCLC) without EGFR mutations or ALK rearrangements. The agency approved durvalumab alongside platinum-containing chemotherapy in the neoadjuvant setting and as monotherapy in the adjuvant setting.

The approval comes shortly after a meeting of FDA’s Oncology Drug Advisory Committee, where agency personnel took AstraZeneca to task for not following its request to include an arm in the approval study, AEGEAN, to clarify whether or not treatment after surgery was necessary. 

Even so, advisers at the July 25 meeting voted “yes” to approving the neoadjuvant/adjuvant indication to give patients another immunotherapy option in NSCLC. However, the committee voted unanimously that, going forward, the agency should require — instead of simply request — that companies seeking combined neoadjuvant/adjuvant NSCLC indications show that patients actually need treatment after surgery. 

The new approval is durvalumab’s first indication for resectable NSCLC. The agent has been previously approved for unresectable or metastatic disease as well as extensive-stage small cell lung cancer, locally advanced or metastatic biliary tract cancer, unresectable hepatocellular carcinoma, and advanced or recurrent endometrial cancer. 

AEGEAN included 802 patients with previously untreated and resectable stage IIA-IIIB squamous or nonsquamous NSCLC. Patients were randomly assigned to receive either durvalumab (400 patients) or placebo (402 patients) on a background of platinum-based chemotherapy every 3 weeks for four cycles then, following surgery, durvalumab or placebo once a month for a year. 

The pathologic complete response rate was 17% in the durvalumab arm vs 4.3% in the placebo arm. At 12 months, event-free survival was 73.4% with durvalumab vs 64.5% with placebo. Overall survival differences have not been tested for statistical significance, but there was “no clear detriment” with durvalumab, FDA said in a press release. 

Adverse reactions in 20% or more of durvalumab recipients included anemia, nausea, constipation, fatigue, musculoskeletal pain, and rash; 1.7% of durvalumab recipients and 1% of placebo recipients could not have surgery because of side effects during neoadjuvant treatment. 

The dosage for patients weighing > 30 kg is 1500 mg every 3 weeks before surgery and every 4 weeks afterward. For patients who weigh less than that, the recommended dosage is 20 mg/kg. 

Durvalumab costs around $1,053 for 120 mg, according to drugs.com.

TOPLINE:

Among patients with overweight or obesity, frontline immunotherapy for advanced non–small cell lung cancer (NSCLC) was not associated with a survival benefit compared with conventional chemotherapy. Overall, however, compared with low body mass index (BMI), overweight or obesity was associated with a lower risk for mortality among patients receiving either therapy.

METHODOLOGY:

• The association between BMI and overall survival in patients with cancer who receive immunotherapy or conventional chemotherapy in the frontline remains unclear. Patients with cancer and obesity are generally considered to have a worse prognosis, but some data suggest an obesity paradox, where patients with cancer and a higher BMI demonstrate better overall survival following immunotherapy or chemotherapy.
• To clarify whether (or how) BMI affects overall survival outcomes and the optimal frontline treatment choice, researchers evaluated 31,257 patients with advanced NSCLC from Japan who received immune checkpoint inhibitors (n = 12,816) or conventional chemotherapy (n = 18,441).
• Patient outcomes were assessed according to weight categories and frontline therapy type (immune checkpoint inhibitors or conventional chemotherapy), with overall survival as the primary outcome.
• A BMI < 18.5 was considered underweight, 18.5-24.9 was considered normal weight, 25.0-29.9 was considered overweight, and ≥ 30.0 was considered obese.

TAKEAWAY:

• In the overall population, regardless of weight, patients who received chemotherapy had a higher mortality rate than those who received immunotherapy — 35.9% vs 28.0%, respectively — over a follow-up of 3 years.
• However, overweight or obesity was associated with a lower risk for mortality compared with a lower BMI among patients with advanced NSCLC, regardless of whether they received immune checkpoint inhibitor therapy or conventional chemotherapy.
• Among patients who received immunotherapy, the risk for mortality decreased steadily as BMI increased from 15 to 24 and then increased at higher BMIs, indicating a U-shaped association.
• Immunotherapy was associated with a significant improvement in overall survival compared with conventional chemotherapy among patients with a BMI < 28; however, researchers observed no difference in overall survival between the two therapies in those with a BMI ≥ 28.

IN PRACTICE:

Overall, “these results support the presence of the obesity paradox in patients with [advanced] NSCLC who underwent either therapy,” the authors concluded.

But when focused on patients in the higher BMI group, there was no overall survival benefit with the frontline immunotherapy vs the conventional chemotherapy. “Immunotherapy therapy may not necessarily be the optimal first-line therapy for patients with overweight or obesity,” the authors wrote, adding that “the use of conventional chemotherapy should also be considered.”

SOURCE:

The study, led by Yasutaka Ihara, PharmD, Osaka Metropolitan University, Osaka, Japan, was published online in JAMA Network Open.

LIMITATIONS: 

Retrospective design has inherent bias. PD-L1 status was not known, and the inclusion of Japanese population may have limited the generalizability of the findings. 

DISCLOSURES:

This study received funding from the Graduate School of Medicine, Osaka Metropolitan University. Several authors reported receiving personal fees from various pharmaceutical sources.
