Malnutrition is common in cancer patients and can occur throughout a patient’s disease course. The contributors to the clinical syndrome of cancer cachexia are often multifactorial, and produced by the cancer and associated pro-inflammatory response. Since cancer cachexia is a multifactorial syndrome, a multimodal therapeutic approach is ideal. A key component of therapy is identifying and managing symptom barriers to adequate oral intake, known as nutritional impact symptoms (NIS). NIS are associated with reduced intake and weight loss in patients with advanced cancer, and aggregate NIS are a predictor of survival in patients with Head and Neck Cancer and in patients undergoing surgery for esophageal cancer. Currently, there are no guidelines regarding the specific management of NIS in oncology patients. Experience from specialist centers suggest relatively simple assessments and inexpensive interventions are available for the diagnosis and treatment of NIS. We present three patient cases from a cachexia clinic, where NIS management decreased symptom burden and improved clinical outcomes such as weight and physical performance.

e24079 Background: Fatigue is common in patients undergoing radiotherapy (RT). Melatonin, an inexpensive natural supplement, may improve symptoms and attenuate the side effects of RT. The effect of melatonin for prevention of fatigue and other symptoms was evaluated in a double-blind placebo-controlled trial. Methods: Early-stage or ductal carcinoma in-situ breast cancer patients ≥ 18 years, female, Eastern Cooperative Oncology Group performance status (ECOG PS) < 3, hemoglobin ≥9 g/dL. RT with curative intent, randomized 1:1 to melatonin 20 mg or oral placebo, starting night before RT initiation until 2 weeks post-RT. Sample size of 142 evaluable patients in each arm for 80% power and interim analysis at mid recruitment using the unified family method rho = 0.3. Randomization stratified to RT duration (< 3 weeks, ≥3 weeks) and prior chemotherapy. Primary outcome : Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue subscale after completion of RT with additional scores measured at baseline, 2 and 8 weeks post-RT. Secondary outcomes : FACIT-F subscales, Edmonton Symptom Assessment System (ESAS) and Patient Reported Outcomes Measurement Information System (PROMIS) Fatigue-Short Form 8a. Secondary analyses reported using an F-test at a 5% significance level. Results: For this interim analysis, 85 patients screened; 80 randomized; 39 received melatonin and 38 placebo. 72 included in the analysis as 5 patients had no post baseline FACIT score. Characteristics of age, race, and ECOG PS similar in both arms. Treatment X time for FACIT-Fatigue not significant for melatonin compared to placebo (p .83). FACIT physical, emotional, and functional well-being scores not significantly different (p .35, .62, and .71) but showing a trend for social well-being (p .06). PROMIS scores not changed over time (p .34). ESAS individual symptoms of anxiety, well-being, drowsiness, poor appetite, nausea, pain, shortness of breath, sleep and tiredness not significant, except for depression (p.04). However, a decrease of 0.01 unit in depression score is not considered clinically significant. No grade 3 or 4 adverse events. No participants died during study, 2 died after study completion from breast cancer recurrence. 16 withdrew prior to study completion because of adverse events, unrelated hospitalizations, RT discontinuation, and COVID-19 precautions. Trial was stopped based on statistical analysis demonstrating no difference for primary outcome and imminent expiry of available drug. Discontinuation was approved by Data Safety Monitoring Committee. Conclusions: Melatonin did not prevent fatigue in patients with early stage breast cancer undergoing RT. Melatonin also demonstrated no benefit for other symptoms, except depression. Analysis showed little evidence of an effect, and the trial was terminated early. Clinical trial information: NCT02332928.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
