Applied molecular profiling: evidence-based decision-making for anticancer therapy
Applied molecular profiling is a method for helping clinicians select the most appropriate therapy for a patient with cancer by determining the level of gene and/or protein expression within the cancer and comparing that expression pattern with the expression profiles of cancers with known outcomes. This approach facilitates the development and selection of tumor-specific therapies based on the identification of biomarkers within a tumor. Molecular characterization techniques such as immunohistochemistry, microarray analysis, and fluorescence in situ hybridization have facilitated identification and validation of a number of important solid tumor biomarkers, including HER2/neu, EGFR, EML4/ALK, and KIT, and can also be used to identify biomarkers (eg, BCR-ABL, CD20, CD30) in various hematologic malignancies. It is of note that molecular profiling can be used to identify targets in tumors for which a therapeutic agent may already be available, thus avoiding the administration of an unproven investigational agent. As the field of molecular profiling continues to evolve and next-generation techniques such as exome sequencing – sequencing 1% of the genome – and whole gene sequencing gain currency, biomarker identification and analysis will become less expensive and more efficient, and possibly allow for a pathway-oriented approach to treatment selection. Wider acceptance and use of molecular profiling should therefore help practicing physicians and oncology researchers keep pace with advances in the understanding of oncogenic expression in various malignancies and encourage the use of molecular profiling in earlier stages of cancer rather than as an option of last resort...

Biomarkers of small intestinal mucosal damage induced by chemotherapy: an emerging role for the 13C sucrose breath test
Gastrointestinal mucosal toxicity is extremely common following cytotoxic therapies. The alimentary mucosa is particularly susceptible to injury and dysfunction, leading to many debilitating complications. Despite much research, there is currently no single noninvasive biomarker to detect gut injury. Several biomarkers have been investigated in the context of gastrointestinal diseases, which may prove useful in the oncology arena. Identification of a biomarker that is easy to obtain and measure and that accurately identifies mucosal damage would allow for improved patient diagnosis of toxicities and for personalized treatment regimens. In this review, we highlight the effectiveness of urine and breath tests as potential clinically effective biomarkers, with significant focus placed on the emerging role of the carbon-13 sucrose breath test (13C SBT). The 13C SBT provides a simple, noninvasive, and integrated measure of gut function. The 13C SBT also has the potential to monitor gut function in the setting of cytotoxic therapy–induced mucositis, or in the assessment of the efficacy of antimucositis agents.

Impact of pretreatment PET on disease control and treatment decisions in locoregionally advanced esophageal cancer patients treated with chemoradiotherapy
Most patients with esophageal cancer are diagnosed with locoregionally advanced disease at presentation, with an overall 5-year survival rate of 19%.1 Clinical trials have failed to specify the optimal treatment regimen; however, a multimodal approach to therapy is considered the standard of care for patients with locoregionally advanced disease.2 Most often, patients are treated with chemoradiotherapy with or without subsequent esophagectomy. Curative-intent interventions for advanced esophageal cancer are necessarily aggressive and may be associated with significant morbidity and even treatment-related mortality. Appropriate selection of patients for intervention is necessary so that those who are most likely to benefit can initiate curative-intent therapy, whereas those who are unlikely to benefit from intervention may be appropriately initiated on less toxic palliative-intent treatment. The use of positron emission tomography (PET) in esophageal cancer staging has improved the ability to detect distant disease at diagnosis,3-7 an important factor in determining the appropriate treatment regimen and prognosis…

Predicting life expectancy in patients with advanced incurable cancer: a review
ABSTRACT
Oncologists frequently face the difficult task of estimating prognosis in patients with incurable malignancies. Their prediction of prognosis informs decision-making ranging from recommendations of cancer treatments to hospice enrollment. Unfortunately, physicians’ estimates of prognosis are often inaccurate and overly optimistic. Further, physicians often fail to disclose their prognosis estimates, despite patient wishes to the contrary. Several studies have examined patient factors that might improve physicians’ prognostic accuracy, including performance status, clinical symptoms and laboratory values. Prognostic models have been developed and validated but, to date, none are able to provide accurate estimates throughout the spectrum of advanced illness. This review examines tools utilized to predict life expectancy for patients with advanced, incurable cancer.

Utilization of radiotherapy services by a palliative care unit: pattern and implication
Background The role of radiotherapy in palliation is well recognized. Analyzing referrals from an inpatient palliative care unit to the radiation oncology service may help in planning palliative care services and educational programs.
Objective To determine the pattern and rate of referrals from a PCU to the RO service at a tertiary oncology facility in Saudi Arabia.
Methods Referrals from the PCU to the RO service were prospectively identified over the period beginning November 27, 2007 and ending March 9, 2011. The appropriateness of referrals was determined by 2 radiation oncologists.
Results Of the 635 cancer admissions to the PCU, 25 (3.9%) referrals to RO were made, and 32 sites were irradiated. All patients had a poor performance status (ECOG 3). The most common areas irradiated were vertebrae (40.6%), pelvis (18.7%) and other bony structures (28.1%). Pain control was the most frequent reason for referral (87.5%). Only one referral was regarded by the RO service as inappropriate, indicating that 96% of the referrals were appropriate. The mean time lapse between referral and starting radiation was 4 3.6 days. A total of 75% of the patients died in the PCU within a median of 30 days post radiotherapy.
Conclusion The small minority of patients in the PCU referred for radiotherapy were deemed appropriate referrals by the radiation oncologists despite their poor performance status and limited time remaining. When planning a PCU with similar admission criteria, the availability of a radiotherapy facility in close proximity may not be a priority.

Malignant phyllodes tumor of the prostate and seminal vesicle: an unusual presentation
A 58-year-old man was admitted to hospital with gross hematuria and a history of a prostate nodule that had been unchanged in size over a period of 3 years. A digital rectal examination revealed a nodule, confirmed by pelvic computed tomography and magnetic resonance imaging scans. Microscopic findings from a transrectal ultrasound-guided biopsy of the prostate revealed phyllodes tumor of the prostate and seminal vesicle, with well-differentiated fibrosarcoma and undifferentiated sarcoma. An initial prostate-specific antigen (PSA) value was 2 ng/mL (normal, less than 4 ng/dL). Over time, the mass grew in size and caused abdominal bloating, bladder outlet obstruction, and kidney failure. A radical prostatectomy was performed and the patient had an uneventful postoperative course. Thereafter, the patient received adjuvant radiation therapy. A few months after surgery, the symptoms worsened and imaging revealed a recurrence and metastasis to his lungs. The patient is currently receiving palliative chemotherapy.

Measuring priority symptoms in advanced bladder cancer: development and initial validation of a brief symptom index
Background Improved measurement of clinically meaningful symptoms is needed in advanced bladder cancer.
Objective This study developed and examined the initial reliability and validity of a new measure of advanced bladder cancer specific symptoms, the NCCN-FACT Bladder Symptom Index-18 (NFBlSI-18), which assesses the symptoms perceived as most important by patients and oncology clinical experts.
Methods A total of 31 individuals with advanced bladder cancer rated the importance of 28 symptoms. In addition, 10 oncology clinical experts rated symptoms as treatment- or disease-related. Patient-rated symptoms were reconciled with published clinicians’ symptom priorities, producing the NFBlSI-18. Participants completed measures of quality of life (QoL) and performance status to examine initial validity.
Results An 18-item symptom index for advanced bladder cancer included 3 subscales: disease-related symptoms, treatment side effects, and general function/well-being. Lower scores indicate greater symptom burden. Preliminary reliability reveals good internal consistency for the full NFBlSI-18 ( 0.83). The NFBlSI-18 was significantly associated with QOL criteria and performance status, in the expected direction.
Limitations Limitations include the cross-sectional design and the relatively low reliability of the disease-related symptoms subscale.
Conclusion The NFBlSI-18 demonstrates preliminary evidence as a valid brief measure of the most important symptoms of advanced bladder cancer, as rated by both patients and oncology clinical experts. The NFBlSI-18 should have greater acceptability to regulatory authorities than previously developed questionnaires.

Palliative care training and associations with burnout in oncology fellows
ABSTRACT
Background Burnout among physicians can lead to decreased career satisfaction, physical and emotional exhaustion, and increased medical errors. In oncologists, high exposure to fatal illness is associated with burnout.
Methods The Maslach Burnout Inventory, measuring Emotional Exhaustion (EE), Depersonalization (DP), and Personal Accomplishment (PA), was administered to second-year US oncology fellows. Bivariate and multivariate analyses explored associations between burnout and fellow demographics, attitudes, and educational experiences.
Results A total of 254 fellows out of 402 eligible US fellows responded (63.2%) and 24.2% reported high EE, 30.0% reported high DP, and 26.8% reported low PA. Over half of the fellows reported burnout in at least one domain. Lower EE scores were associated with the fellows’ perceptions of having received better teaching, explicit teaching about certain end-of-life topics, and receipt of direct observation of goals-of-care discussions. Fellows who reported better overall teaching quality and more frequent observation of their skills had less depersonalization. Fellows who felt a responsibility to help patients at the end of life to prepare for death had higher PA.
Limitations This survey relies on the fellows’ self-reported perceptions without an objective measure for validation. Factors associated with burnout may not be causal. The number of analyses performed raises the concern for Type I errors; therefore, a stringent P value (.01) was used.
Conclusions Burnout is prevalent during oncology training. Higher-quality teaching is associated with less burnout among fellows. Fellowship programs should recognize the prevalence of burnout among oncology fellows as well as components of training that may protect against burnout.

Resistance exercise interventions during and following cancer treatment: a systematic review
Findings from prior systematic reviews suggest that exercise results in meaningful improvements in many clinically relevant physiologic and quality of life (QoL) outcomes during and following cancer treatment. However, the majority of exercise-cancer studies have focused upon the benefits of aerobic exercise (AE) and knowledge of the efficacy of resistance exercise (RE) alone as a supportive care intervention for cancer patients and survivors remains limited. Consequently, the purpose of this review was to provide the first systematic evaluation of the effects of RE alone upon clinically relevant physiologic and QoL outcomes during and following cancer treatment. Literature searches were conducted to identify studies examining RE interventions in cancer patients and survivors. Data were extracted on physiologic (fitness, physical function, and body composition) and QoL (fatigue, psychological well-being, and cancer-specific and global QoL outcomes. Cohen’s d effect sizes were calculated for each outcome. A total of 15 studies (6 in samples undergoing active cancer treatment and 9 in samples having completed cancer treatment) involving 1,077 participants met the inclusion criteria. Findings revealed that, on average, RE resulted in large effectsize improvements in muscular strength (d 0.86), moderate effect-size improvements in physical function (d 0.66), and small effect-size improvements in body composition (d 0.28) and QoL (d 0.25) outcomes. The effect sizes observed following RE are comparable in magnitude to the effects of exercise interventions reported in prior comprehensive reviews of the exercise cancer literature which primarily focused upon AE. Additionally, the methodologic quality of the studies was generally strong. Taken collectively, results of this systematic review suggest that RE is a promising supportive care intervention that results in meaningful improvements in clinically relevant physiologic and QoL outcomes during and following cancer treatment.

Findings revealed that, on average, RE resulted in large effectsize improvements in muscular strength (d 0.86), moderate effect-size improvements in physical function (d 0.66), and small effect-size improvements in body composition (d 0.28) and QoL (d 0.25) outcomes. The effect sizes observed following RE are comparable in magnitude to the effects of exercise interventions reported in prior comprehensive reviews of the exercise cancer literature which primarily focused upon AE. Additionally, the methodologic quality of the studies was generally strong. Taken collectively, results of this systematic review suggest that RE is a promising supportive care intervention that results in meaningful improvements in clinically relevant physiologic and QoL outcomes during and following cancer treatment.

Digital acrometastasis: an unusual first presentation of an occult lung cancer
A57-year-old Caucasian man with a 32 pack-year history of smoking presented to the prime care clinic with a 2-week history of left index finger pain, redness, and swelling after sustaining a minor injury while closing his car door. Physical examination revealed a blackish discoloration of the skin. An X-ray of his left hand showed complete demineralization of the distal phalanx of the left index finger (Figure 1). The pain did not respond to NSAIDS, narcotics, and antibiotics. He subsequently underwent partial amputation of the finger. Pathology from the surgical specimen revealed a “poorly differentiated metastatic small-cell carcinoma” (Figure 2). He denied any dyspnea, cough, fever, night sweats, or loss of weight or appetite. The results of a computerized tomography scan of his thorax (Figure 3), abdomen, and pelvis revealed a large right lower lobe lung mass of 6.2 cm 4.2 cm adjacent to the right lower lobe bronchus that was consistent with lung cancer associated with pulmonary, hepatic, nodal, and skeletal metastasis. Magnetic resonance imaging of the brain showed multiple metastatic lesions throughout the brain, including the cerebellum. An MRI of the spine showed extensive metastatic lesions involving the thoracic vertebrae, T4 –T12, and the lumbar vertebra, L2. Given the extensive metastases and poor prognosis, the patient chose hospice care and palliative services. Discussion Digital acrometastases represent only 0.1% of all skeletal metastases.1 They have been described with various malignancies, including breast, gastrointestinal tract, head and neck, and small-cell and non–small-cell lung carcinomas.1,2 Metastases to the hand are most commonly caused by bronchogenic carcinomas,1-7 whereas foot metastases are seen with tumors originating in the gastrointestinal or genitourinary tracts.6,7 The most commonly involved bones are the phalanges in the hand and the tarsal bones in the foot.7,8 Acrometastases account for about 1 out of 500 lung cancers that present with bony metastases.2 Prognosis is grim, with a mean survival of 3– 6 months after presentation.1,2 Although acrometastasis from lung cancer itself is rare, occult lung cancer presenting as metastasis to the finger is even more unusual.
