Health-related quality of life in a randomized trial of neoadjuvant chemotherapy or chemoradiotherapy plus surgery in patients with oesophageal cancer (NeoRes trial)

BACKGROUND: There are few data comparing health-related quality of life (HRQoL) after neoadjuvant chemotherapy alone (nCT) compared with neoadjuvant chemoradiotherapy (nCRT) in patients with oesophageal cancer. METHODS: 5-fluorouracil over 24 h on days 1-5 in three 21-day cycles (nCT) or the same chemotherapy regimen, but with the addition of 40 Gy radiotherapy (nCRT). HRQoL data were collected at baseline, after neoadjuvant therapy and at 1, 3 and 5 years after surgery. The European Organisation for Research and Treatment of Cancer (EORTC) core questionnaire QLQ-C30 and disease-specific modules were used. RESULTS: Of 181 patients randomized, 165 were included in the analysis of HRQoL. In a direct comparison between the allocated treatments, odynophagia after completion of neoadjuvant therapy but before surgery (P = 0·047) and troublesome coughing at 3 years' follow-up (P = 0·011) were more pronounced in the nCRT arm. In the longitudinal analyses within each treatment arm, a large deterioration in HRQoL was noted at 1 year. Some recovery was seen in both arms over time but, after 3 and 5 years, patients in the nCRT arm reported more symptoms compared with baseline than patients in the nCT arm. CONCLUSION: HRQoL after multimodal treatment for cancer of the oesophagus or gastro-oesophageal junction was impaired and more pronounced in patients who underwent nCRT, with only partial recovery over time.
