INTRODUCTION: Modern multidisciplinary cancer treatments aim at obtaining minimal influence on patients' quality of life (QoL). The purpose of this study was to assess QoL and correlate it with dose-volume parameters of organ at risks (OARs) in patients who received adjuvant radiotherapy for endometrial and cervical cancers.
MATERIALS AND METHODS: We administered the EORTC QLQ-C30 and EN24 or CX24 questionnaires to 124 patients, 100 with endometrial cancer and 24 with cervical cancer treated with postoperative radiotherapy ± chemotherapy in regular follow-up. Bladder function, fecal incontinence or urgency and sexual functioning were investigated and correlated with dose-volume parameters of OAR by multiple linear regression analysis. This correlation was assessed by R (2) value.
RESULTS: QoL was very high in the majority of patients (82.3 % of patients). Few patients referred urinary incontinence (3.2 %) or abdominal discomfort of high grade (4.0 %). We found a significant correlation between bladder V40, i.e., absolute percentage of bladder volume that received a dose of 40 Gy, and global health status (p < 0.05, R (2) = 0.17), urinary urgency (p < 0.05, R (2) = 0.24), urinary incontinence (p < 0.05, R (2) = 0.23) and dyspareunia (p < 0.05, R (2) = 0.04). We found also a correlation between global health status and mean dose to vagina (p < 0.05, R (2) = 0.17) and between maximum dose to lumbo-sacral plexus and abdominal pain (p < 0.05, R (2) = 0.07).
CONCLUSIONS: Women treated with surgery and adjuvant radiotherapy for endometrial and cervical cancers have good QoL with minimal limitations of daily activities. QoL was correlated with dose-volume parameters such as bladder V40, mean dose to vagina, maximum dose to trigone and LSP.
