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.

Cancer cachexia is a syndrome characterized by weight loss with accompanying loss of muscle and/or fat mass and leads to impaired patient function and physical performance and is associated with a poor prognosis. It is prevalent in older adults with cancer; age-associated physiologic muscle wasting and weakness, also known as sarcopenia, can compound deficits associated with cancer cachexia in older adults and makes studying this condition more complex in this population. Multiple measurement options are available to assess the older patient with cancer and cachexia and/or sarcopenia including anthropometric measures, imaging modalities such as Dual X-ray absorptiometry (DEXA) and Computed Tomography (CT), muscular strength and physical performance testing, and patient-reported outcomes (PROs). A geriatric assessment (GA) is a useful tool when studying the older patient with cachexia given its comprehensive ability to capture aging-sensitive PROs. Interventions focused on nutrition and increasing physical activity may improve outcomes in older adults with cachexia. Efforts to develop targeted pharmacologic therapies with cachexia have not been successful thus far. Formal treatment guidelines, an updated consensus definition for cancer cachexia and the development of a widely adapted assessment tool, much like the GA utilized in geriatric oncology, could help advance the field of cancer cachexia over the next decade.

Abstract Background: Pancreatic cancer is associated with development of cachexia, a wasting syndrome thought to limit survival. Few studies have longitudinally quantified peripheral tissues or identified biomarkers predictive of future tissue wasting. Methods: Adipose and muscle tissue were measured by computed tomography (CT) at diagnosis and 50 to 120 days later in 164 patients with advanced pancreatic cancer. Tissue changes and survival were evaluated by Cox proportional hazards regression. Baseline levels of circulating markers were examined in relation to future tissue wasting. Results: Compared with patients in the bottom quartile of muscle change per 30 days (average gain of 0.8 ± 2.0 cm2), those in the top quartile (average loss of 12.9 ± 4.9 cm2) had a hazard ratio (HR) for death of 2.01 [95% confidence interval (CI), 1.12–3.62]. Patients in the top quartile of muscle attenuation change (average decrease of 4.9 ± 2.4 Hounsfield units) had an HR of 2.19 (95% CI, 1.18–4.04) compared with those in the bottom quartile (average increase of 2.4 ± 1.6 Hounsfield units). Changes in adipose tissue were not associated with survival. Higher plasma branched chain amino acids (BCAA; P = 0.004) and lower monocyte chemoattractant protein-1 (MCP-1; P = 0.005) at diagnosis were associated with greater future muscle loss. Conclusions: In patients with advanced pancreatic cancer, muscle loss and decrease in muscle density in 2 to 4 months after diagnosis were associated with reduced survival. BCAAs and MCP-1 levels at diagnosis were associated with subsequent muscle loss. Impact: BCAAs and MCP-1 levels at diagnosis could identify a high-risk group for future tissue wasting.
