Quality of life and cognitive functioning impairment associated with cisplatin-based chemotherapy in testicular cancer survivors.

Abstract

e21607 Background: Testicular cancer (GCT) survivors are at risk for different types of late treatment sequelae. This study aimed to evaluate long-term quality of life (QOL), sexual (SexF) and cognitive functioning (CogF) issues resulting from cisplatin-based chemotherapy. Methods: QoL, SexF and CogF data were prospectively collected in 83 GCT survivors with median 9 year follow-up (range 5-32). The chemotherapy group (CTG) consisted of 53 and 18 patients receiving a cisplatin cumulative dose of ≤ 400mg/m2 (LCD) and > 400mg/m2 (HCD), respectively. The control group (CG) included 12 patients treated with orchiectomy (6 pts) and adjuvant radiotherapy (6 pts). Data were collected using EORTC QLQ-C30, QLQ-TC26, FACT-Cog and sexual functioning questionnaires and analyzed according to the scoring guidelines. Results:The CTG survivors had significantly (all p < 0.05) more limitations while working or doing daily activities (37% vs 8%), needed to rest more often (61% vs 33%) and feared the disease relapse more often (73% vs 50%) compared to the CG. A subscale for family problems within QLQ-TC26 have shown higher impairment in the CTG vs. CG (mean score ± SEM: 54.2 ± 26.7 vs. 38.8. ± 7.3, P < 0.05). Cognitive abilities were perceived better in CG vs. CTG (mean score 24.5 ± 1.8 vs. 20.5 ± 0.7, P < 0.05). The CG surivors had higher education level and fathered more children compared to the CTG. The CTG felt more unsettled than the CG (all P < 0.05), however the impact of perceived cognitive impairment on their lives did not significantly differ ( P = 0.4). Patients who received HCD have suffered from dyspnea more often than patients treated with LCD (mean dyspnea subscale score ± SEM: 22.2 ± 4.4 vs 8.9 ± 2.6, P < 0.05). The HCD group also reported more difficulties to concentrate while watching television/reading newspaper and struggled to name things during conversation compared with the LCD group ( P < 0.05 for both). No impairment in sexual functioning was reported. Conclusions: Our study shows thatGCT survivors cured with cisplatin-based chemotherapy suffered from QoL issues and their perception of cognitive abilities was altered. The HCD of cisplatin further impaired several QoL and cognitive aspects.
