The Patient's perspective on radiation therapy for anal cancer: Evaluation of expectations and stigma.

Background: Little is known regarding anal cancer patients' perspectives on undergoing radiation therapy. Additionally, the stigma surrounding anal cancer diagnosis warrants a better understanding of the barriers to complete disclosure in patient-healthcare team interactions.

Methods: Included patients had squamous cell carcinoma of the anus treated with definitive chemoradiation (CRT) from 2009 to 2018. Survey questions were adapted from the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire and Discrimination and Stigma Scale.

Results: A total of 46 anal cancer patients who underwent CRT were surveyed, of which 72% responded. 73% of respondents indicated little to no pre-treatment knowledge of CRT. 70% reported overall short-term effects as worse than expected, most commonly with bowel habits (82%), energy (73%), and interest in sexual activity (64%). 39% reported overall long-term effects to be worse than expected, most commonly with changes to bowel habits (73%), sexual function (67%), and interest in sexual activity (58%). However, 94% agreed they were better off after treatment. Regarding stigma, a subset reported hiding their diagnosis (12%, 24%) and side effects (24%, 30%) from friends/family or work colleagues, respectively, and 15% indicating they stopped having close relationships due to concerns over stigma.

Conclusions: Although patients' perceptions of the severity of short-term CRT side effects were worse than expectations, the vast majority agreed they were better off after treatment. Targeted counseling on common concerns may improve the anal cancer treatment experience. A notable subset reported stigma associated with treatment, warranting further evaluation to understand the impact on the patient experience.
