Abstract

Background: The CAO/ARO/AIO trial has shown that oxaliplatin added to preoperative chemoradiotherapy and postoperative chemotherapy significantly improved disease-free survival in locally advanced rectal cancer (LARC). Here, we present a post-hoc analysis of quality of life (QoL) in disease-free patients. Patients and methods: Between 2006 and 2010, 1236 patients with LARC were randomly assigned either to preoperative chemoradiotherapy followed by total mesorectal excision and postoperative chemotherapy (N = 623) or combined with oxaliplatin (N = 613). QoL questionnaires (EORTC QLQ-C30, colorectal module CR38) were completed at baseline, after postoperative chemotherapy and during follow-up. Analysis was performed according intent-to-treat. Results: Available questionnaires (baseline) were 82% (N = 512) in the control and 84% (N = 513) in the investigational group. Response rates were 49% (533 of 1086) at 1 year and 43% (403 of 928) at 3 years. Global health status (GHS) for disease-free patients was stable in both groups (range 0–100). At baseline: standard arm 62.0 (mean, SD 21.6; N = 491) versus oxaliplatin arm 63.2 (mean, SD 22; N = 503); at 3 years: 69.4 (SD 19.3; N = 187) versus 65.4 (SD 22.2; N = 202). After treatment and at 3 years, no significant differences (≥10 points) between groups were found in QoL subscales. Disease-free patients experiencing neurotoxic side-effects (grade 1–4) showed reduced GHS at 3 years versus patients without neurotoxicity (mean 59.2 versus 69.3; P < 0.001), while grade 3–4 rate was low. Conclusion: The addition of oxaliplatin was not associated with worse overall QoL. This information is of interest to patients in many ongoing rectal cancer trials. Trial registration information: NCT00349076.
