e21567 Background: For patients diagnosed with cancer, depression and anxiety represent a common and significant burden, which has been proposed to not only affect quality of life but to potentially shorten duration of life as well. This study examines the influence of patient reported symptoms of anxiety and depression on overall distress and mortality in patients undergoing radiation therapy. Methods: As part of their intake paperwork, patients undergoing radiation therapy completed distress screening that included 29 questions regarding their level of concern with various factors related to their care as well as their overall distress level. This information and other parameters including demographics, site of primary disease, use of chemotherapy, presence of metastasis, and last known status were recorded for analysis. Answers regarding degree of concern for “feeling down or depressed”, “loss of interest in my usual activities”, and “feeling nervous or anxious” were examined for influence on study endpoints. Results: Results for final analysis were available from 519 patients undergoing therapy from April 2010 to May 2016. The cohort’s average age was 66yrs, 71% were treated curatively, and 29% were treated palliatively. The most common treatment sites were breast (27%), thorax (16%), H&N (12%), GU (12%), GI (10%), and CNS (7%). Significant correlation was found between level of concern with symptoms of anxiety and depression and level of overall distress (P < 0.001, Kruskal-Wallis Rank Sum Test). Significance remained on separate analysis of curative and palliative subgroups. No significant correlation was found for 1 or 2 year survival on either single or multivariate analysis of curative or palliative patients. Conclusions: Depression and anxiety are common conditions among cancer patients, and can contribute significantly to their overall distress. Although no effects on mortality were demonstrated on initial follow-up of this cohort, it remains evident that attention to emotional well-being is critical in the care of such patients. Additional investigations can be pursued regarding ideal interventions for patients identified by such screening.

182 Background: The purpose of this study was to examine the associations of three different measures of anxiety and depression with patient reported distress (PRD) level and survival after radiotherapy (RT). Methods: 518 patients who underwent RT between 2012 and 2016 were included in this retrospective study. PRD was assessed at the time of RT using the NCCN thermometer and a 30 question survey of distress related items. PRD and clinical and demographic data was retrospectively collected and analyzed. The three measures this study focused on that assessed patient anxiety and depression involved asking patients about their level of concern regarding feeling down, regarding loss of interest, and regarding feeling nervous. Associations between baseline patient characteristics and survival after start of RT were evaluated using single variable Cox proportional hazards regression models. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated. Associations of level of concern regarding patient anxiety/depression with survival after RT were evaluated using single variable and multivariable Cox proportional hazards regression models. Results: Overall, PRD level and concern regarding anxiety/depression were positively correlated (p < 0.001). Additionally, there was a significant association between level of concern regarding feeling down and palliative patients (p = 0.03). There was also a significant association between level of concern regarding loss of interest and palliative patients (p = 0.03), with level of concern highest for thorax, breast, and head and neck. There was also a significant different between level of concern regarding feeling nervous and gender (p = 0.05). There was not a significant difference between any of the three measures and survival after RT (all p ≥ 0.21). Conclusions: Anxiety and depression in patients receiving palliative and curative RT was associated with overall distress. Baseline screening of PRD may identify patients who would benefit from intervention to address the causes of their underlying anxiety and depression.

Key Clinical Message Myxoinflammatory fibroblastic sarcoma is a rare sarcoma which typically presents in the extremities and is treated by definitive surgery. In recurrent disease, the reported utilization of radiotherapy is increasing, and more modern techniques such as intensity‐modulated radiotherapy may be improving long‐term outcomes.

Prostate cancer is the most common malignancy of men in the United States. Small-cell carcinoma (SCC), which typically presents as an aggressive lung malignancy, is a rare diagnosis within the setting of prostate cancer pathology. Due to its limited prevalence, little information regarding the treatment and prognosis of this disease in large populations is available. To date our current knowledge base is largely limited to case reports and retrospective case reviews. The mainstay of treatment for this particular histology most often involves a multimodality approach utilizing chemotherapy in conjunction with radiation therapy, androgen deprivation therapy, or prostatectomy. Here we present the case of an elderly 89-year-old Caucasian male who was diagnosed with SCC of the prostate. Despite proceeding with a course of definitive radiotherapy, the patient experienced rapid progression of disease and ultimately elected to discontinue radiation therapy and receive hospice care.
