Long-term quality of life in non-epithelial ovarian cancer survivors: TMRG-GINECO-Vivrovaire rare tumors case–control study
Résumé
Background: Patients treated for rare ovarian germ cell tumors (GCT) and sex cord stromal tumors (SCST) often experience long-term survival. Treatments include surgery with or without chemotherapy (CT), which can cause late side effects that negatively impact quality of life (QoL). This study assessed long-term QoL among GCT and SCST survivors compared to age-matched healthy women (HW), focusing on patients treated with CT. Methods: Cancer-free GCT and SCST survivors (≥ 2 years post-treatment) were recruited from the INCa French Network TMRG. HW were recruited via the "Seintinelles" platform. Participants completed validated questionnaires assessing QoL (FACT-G/FACT-O), fatigue (MFI), anxiety/depression (HADS), insomnia (ISI), neurotoxicity (FACT/GOG-NTX), cognition (FACT-COG), and sexuality (FACT-O OCS). Clinically relevant differences were defined as ≥ 5% between groups. Results: A total of 144 survivors (99 GCT and 45 SCST) were included and compared with 284 matched HW (median age: 35.2 years). The median time from the end of treatment was 6 years [Q1 3.5-Q3 9.3]. At inclusion, 42% of patients were menopausal compared to 17% of HW (p < 0.001), with reduced sexual QoL. Survivors reported more cognitive impairment (32% vs. 21%, p = 0.025) and severe neurotoxicity (23% vs. 8%, p < 0.001). QoL, fatigue, anxiety/depression, and insomnia scores were similar for patients and HW. Conclusions: With a median of 6 years after CT, most GCT and SCST survivors reported similar overall QoL compared to HW but faced premature menopause, reduced sexual QoL, and persistent cognitive and neurotoxic effects.
