RESUMO
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.

INTRODUCTION: Aggressive cancer treatment is a challenge in elderly patients. The present study aims to assess tolerance in terms of acute toxicity and compliance of concurrent chemo-radiotherapy (cCRT) in a series of patients aged ≥70 years. MATERIALS AND METHODS: Clinical records of patients aged ≥70 years who underwent cCRT between January 2005 and December 2013 were reviewed. Concurrent CRT had curative intent in 134 patients (97.8 %) and palliative intent in 3 patients (2.2 %). Chemotherapy (CT) drugs and schedule were selected according to tumor histology. Radiotherapy median dose was 45.0 Gy (range 11-70 Gy) for curative purposes and 54 Gy (range 40-56 Gy) for palliative purposes. Incidence of acute toxicity and compliance to cCRT were analyzed and correlated with age, Karnofsky Performance Status (KPS), and Charlson Comorbidity Index (CCI). RESULTS: Overall, 137 patients, 82 males (60 %) and 55 females (40 %), median age 74 years (range 70-90 years) were analyzed. Concurrent CRT schedule was completed by 132 patients (96.4 %). Thirty-one of these patients (23.5 %) temporarily interrupted treatment. Hematological toxicity with grade ≥1 was observed in 25 patients (18.2 %), gastrointestinal toxicity in 55 (40.1 %), and genitourinary in 13 (9.5 %). Mucositis with grade ≥1 was recorded in 19 patients (13.9 %). No statistical significant correlation between KPS, CCI, and toxicity was found. A correlation trend between mucositis and patient age (p = 0.05) was observed. CONCLUSION: Concurrent CRT for elderly was feasible and quite well tolerated. Great attention in prescribing CT dose should be paid to limit acute toxicity.
