Radiochemotherapy of locally advanced anal canal carcinoma: prospective assessment of early impact on the quality of life (randomized trial ACCORD 03).

International audienceBACKGROUND AND PURPOSE: The aim of this study was to prospectively assess the quality of life (QOL) of patients treated by concomitant chemo radiation for locally advanced anal canal carcinoma. MATERIALS AND METHODS: We report on a subgroup of 119 patients enrolled in a 306-patient therapeutic intensification prospective trial (ACCORD 03). This trial evaluated the impact on colostomy-free survival of induction chemotherapy and/or high dose radiotherapy (factorial design 2 *2 treatment arms). QOL was assessed both before and 2 months after treatment using the EORTC QLQ-C30 questionnaire as well as a questionnaire relating to anal sphincter conservative treatment (AS-CT). RESULTS: Compared to pre-treatment scores, patients reported significant improvement in their emotional function (+8.4 points p=0.002), global health status (+5.9 points p=0.0007), as well as a decrease in insomnia (-13.8 points p<0.0001), constipation (-12.0 points p<0.0001), appetite loss (-10.3 points p<0.0001) and pain (-9.6 points p=0.0002). The AS-CT degree of satisfaction with intestinal functions score was increased (+11.2 points p
