AbstractIntroductionThe American College of Sports Medicine provided guidelines for exercise prescriptions in cancer survivors for specific cancer‐ and treatment‐related health outcomes. However, there was insufficient evidence to generate exercise prescriptions for 10 health outcomes of cancer treatment. We sought to update the state of evidence.MethodsWe conducted a systematic review of these 10 understudied health outcomes (bone health, sleep, cardiovascular function, chemotherapy‐induced peripheral neuropathy (CIPN), cognitive function, falls and balance, nausea, pain, sexual function, and treatment tolerance) and provided an update of evidence.ResultsWhile the evidence base for each outcome has increased, there remains insufficient evidence to generate exercise prescriptions. Common limitations observed across outcomes included: variability in type and quality of outcome measurement tools, variability in definitions of the health outcomes, a lack of phase III trials, and a majority of trials investigating breast or prostate cancer survivors only.ConclusionWe identified progress in the field of exercise oncology for several understudied cancer‐ and treatment‐related health outcomes. However, we were not able to generate exercise prescriptions due to continued insufficient evidence base. More work is needed to prescribe exercise as medicine for these understudied health outcomes, and our review highlights several strategies to aid in research acceleration within these areas of exercise oncology.

11625 Background: Improving body image and self-esteem are top ASCO priorities in the survivorship care of men with prostate cancer (PCa). Body image and global self-esteem, influenced by physical self-worth, are negatively affected by PCa treatment. We investigate whether exercise can improve physical self-worth in men treated for PCa and if improving self-worth is associated with changes in quality of life (QoL) and mental health. Methods: We performed a secondary analysis of a phase II randomized controlled trial comparing the effects of Exercise for Cancer Patients(EXCAP), a structured, 6-week, home-based exercise intervention, to usual care (UC) in men with non-metastatic PCa receiving radiation or Androgen Deprivation Therapy (ADT). The Physical Self-Perception Profile (PSPP), a valid 30-item questionnaire where higher scores indicate greater physical self-worth, was assessed at pre- and post-intervention. Changes between arms were compared using ANCOVA. Spearman correlations were calculated for pre/post-intervention change scores for PSPP and QoL, depression, and anxiety as measured by the Functional Assessment of Cancer Therapy (FACT), Center of Epidemiologic Studies Depression (CES-D) scale, and State-Trait Anxiety Inventory (STAI), respectively. Results: Fifty-eight men were randomized; average age was 67.1 years. Physical self-worth at baseline moderated the effect of the intervention. Compared to UC, EXCAP improved physical self-worth in those with baseline PSPP scores above the median (p < 0.04). Exercisers with baseline PSPP scores in the top quartile demonstrated a more significant improvement over UC (p < 0.01). Improvements in physical self-worth were associated with improved QoL (r = 0.29, p = 0.04), depression (r = -0.28, p = 0.04) and anxiety (r = -0.30, p = 0.03). Conclusions: Exercise significantly improves physical self-worth in men with PCa on radiation or ADT, and greater physical self-worth is associated with improved QoL, depression and anxiety. Those with higher baseline physical self-worth derived the most benefit from exercise. Exercise should be prescribed to boost self-esteem and body image in men receiving radiation or ADT for PCa.

Abstract Although recent scientific advances have improved our understanding of basic biological mechanisms underlying chemotherapy-induced peripheral neuropathy (CIPN), few interventions are available to prevent or treat CIPN. Although some biological targets from preclinical studies show promise in nonhuman animal models, few targets have been translated to successful clinical trials. To address this problem, the National Cancer Institute’s Symptom Management and Health-Related Quality of Life Steering Committee convened a meeting of experts in the CIPN and oncology symptom management fields to participate in a Clinical Trials Planning Meeting (CTPM). Investigators presented data from preclinical and translational studies for possible CIPN interventions; these were evaluated for readiness of randomized clinical trial testing by experts, and recommendations were provided. Breakout sessions were convened to discuss and develop future studies. The CTPM experts concluded that there is compelling evidence to move forward with selected pharmacological and nonpharmacological clinical trials for the prevention and treatment of CIPN. Several key feasibility issues need to be addressed, however. These include identification of optimal outcome measures to define the CIPN phenotype, establishment of parameters that guide the evaluation of clinically meaningful effects, and adoption of approaches for inclusion of translational and biomarker and/or genetic measures. The results of the CTPM provide support for conducting clinical trials that include both pharmacological and nonpharmacological approaches, alone or in combination, with biomarkers, genetics, or other measures designed to inform underlying CIPN mechanisms. Several working groups were formed to design rigorous CIPN clinical trials, the results of which are ongoing.
