Long-term quality-of-life after neoadjuvant short-course radiotherapy and long-course radiochemotherapy for locally advanced rectal cancer

Abstract

PurposeTo evaluate long-term quality-of-life (QoL) after neoadjuvant short-course radiotherapy (SC-RT) and long-course radiochemotherapy (LC-RCHT) for locally advanced rectal cancer. MethodsBetween 1999 and 2008, 225 patients were treated with curative intent for locally advanced rectal cancer using neoadjuvant SC-RT (n=108) or LC-RCHT (n=117). SC-RT delivered 10×2.9Gy twice daily with immediate surgery. LC-RCHT delivered 28×1.8Gy concomitant with 5-FU based chemotherapy and delayed surgery. A cross-sectional QoL analysis was performed in disease-free patients using the EORTC-QLQ-C30 and EORTC-QLQ-CR29 questionnaires. ResultsAfter a median follow-up of 67months, 133 patients were disease-free of which 120 (90%) returned the QoL questionnaires. Patients in the LC-RCHT cohort had a higher rate of uT4, uN+ and low tumor location. No difference in QoL was observed between SC-RT and LC-RCHT except an improved physical functioning in the LC-RCHT group (p=0.04). Comparing our total patient cohort with the general German population showed no difference in global health status but decreased QoL in several functional and bowel symptom scores. ConclusionsThe finding of comparable long-term QoL after SC-RT and LC-RCHT adds to our knowledge of equivalent oncological outcome and may be useful in the decision making process between the two neoadjuvant approaches.
