Abstract
PURPOSE
Patient-reported outcome (PRO) and National Cancer Institute-Common Terminology Criteria for Adverse Events (NCI-CTCAE) data for patients with squamous cell carcinoma of the anus (SCCA) treated with modern radiation therapy (RT) are lacking. The primary aim of this study was to report bowel and bladder PRO and NCI-CTCAE for patients with SCCA 1 year after RT.
METHODS AND MATERIALS
From 2015 to 2020, we included patients in a prospective Danish national study. Data were collected before treatment (PT) and 1 year after treatment (1Y) using NCI-CTCAE version 4.0, as well as European Organisation for Research and Treatment of Cancer Quality of Life Questionnaires C30 and CR29. We evaluated the combined PRO scores according to the European Organisation for Research and Treatment of Cancer scoring guidelines, and classified changes according to score difference from PT to 1Y as no change (0-5), minor (5-10), moderate (11-20), and major (>20). Raw scores were reported as frequencies of each of the scores: Not at all, a little, quite a bit, and very much.
RESULTS
Of the 270 patients, 81% had complete data sets, including PT and 1Y answers. Functional mean scores were equal to a matched normal population cohort at PT and 1Y. From PT to 1Y, C30 scores were stable despite minor improvements in global health status/quality of life (7.3), emotional functioning (9.3), insomnia (8.0), and appetite loss (7.8). For questionnaire CR29, bowel and bladder symptoms and sore skin improved with minor change (6.2), and buttocks, anal, or rectal pain improved with moderate change (18.3). Flatulence worsened moderately (12.6), and fecal incontinence had minor worsening (7.8). Agreement between PROs and NCI-CTCAE was generally only fair to moderate, especially for quantitative symptoms, such as pain (κ = 0.25).
CONCLUSIONS
For patients with SCCA who underwent definitive RT, only a few patients had high scores (indicating quite a bit or very much frequency of bother) regarding bowel and bladder symptoms.
