Purpose: Dose-escalated chemoradiation (CRT) for locally advanced rectal cancer did not result in higher complete response rates but initiated more tumor regression in the randomized RECTAL-BOOST trial (Clinicaltrials.gov NCT01951521). This study compared patient reported outcomes between patients who received dose-escalated CRT (5 × 3 gray boost + CRT) or standard CRT for 2 years after randomization.Methods and Materials: Patients with locally advanced rectal cancer who were participating in the RECTAL-BOOST trial filled out European Organisation for Research and Treatment of Cancer QLQ-C30 and CR29 questionnaires on quality of life (QoL) and symptoms at baseline, 3, 6, 12, 18, and 24 months after start of treatment. Between-group differences in functional QoL domains were estimated using a linear mixed-effects model and expressed as effect size (ES). Symptom scores were compared using Mann-Whitney U test.Results: Patients treated with dose–escalated CRT (boost group, n = 51) experienced a significantly stronger decline in global health at 3 and 6 months (ES –0.4 and ES –0.4), physical functioning at 6 months (ES –1.1), role functioning at 3 and 6 months (ES –0.8 and ES –0.6), and social functioning at 6 months (ES –0.6), compared with patients treated with standard CRT (control group, n = 64). The boost group reported significantly more fatigue at 3 and 6 months (83% vs 66% respectively 89% vs 76%), pain at 3 and 6 months (67% vs 36% respectively 80% vs 44%), and diarrhea at 3 months (45% vs 29%) compared with the control group. From 12 months onwards, QoL and symptoms were similar between groups, apart from more blood/mucus in stool in the boost group.Conclusions: In patients with locally advanced rectal cancer, dose-escalated CRT resulted in a transient deterioration in global health, physical, role, and social functioning and more pain, fatigue and diarrhea at 3 and 6 months after start of treatment compared with standard CRT. From 12 months onwards, the effect of dose-escalated CRT on QoL largely resolved.
