Abstract

Background: Results from the phase 3 PRODIGE 23 study showed that neoadjuvant chemotherapy (NAC) with mFOLFIRINOX and preoperative chemoradiotherapy improved disease-free survival compared with preoperative chemoradiotherapy in patients with locally advanced rectal cancer. We aimed to assess the health-related quality of life (HRQOL) outcomes from this study.

Patients and methods: A total of 461 patients (231 versus 230 patients) from 35 French hospitals were randomly assigned to either NAC with FOLFIRINOX (oxaliplatin 85 mg/m2, irinotecan 180 mg/m2, leucovorin 400 mg/m2, fluorouracil 2400 mg/m2 over 46 h intravenously every 2 weeks for 6 cycles) followed by preoperative chemoradiotherapy or chemoradiotherapy only. HRQOL was assessed at baseline, during treatments and at 2-year follow-up using the European Organization for Research and Treatment of Cancer QLQ-C30 and QLQ-CR29 questionnaires.

Results: Compared to baseline, HRQOL scores during NAC were better for tumour symptoms but worse for global health status, functional domains, fatigue, nausea/vomiting and appetite loss. During follow-up, improved emotional functioning was observed, but deterioration of body image, increased urinary incontinence, and lower male sexual function were observed. Linear mixed model exhibited a treatment-by-time interaction effect for nausea/vomiting and insomnia symptoms showing a greater deterioration in the standard-of-care group. Only treatment arm and baseline physical functioning were independent significant favourable prognostic factors.

Conclusion: NAC improved tumour-related symptoms and transitorily reduced most functional scores. Adding NAC before chemoradiotherapy and increased physical functioning at baseline were independent significant prognostic factors for longer disease-free survival.
