Abstract 714
Background
To assess the effects of a gonadotropin-releasing hormone agonists (GnRHa) administration in young patients with malignant ovarian germ cell tumour (MOGCT) during chemotherapy on the prevention of chemotherapy-induced ovarian insufficiency.
Methods
This multicenter, retrospective study was conducted at fifteen sites in Korea and enrolled 354 patients between January 1995 and January 2018. Among them 227 patients were included in this study according the inclusion criteria: 1) patients diagnosed as pathologically malignant germ cell tumours of the ovaries, 2) who have preserved the uterus and at least one ovary, 3) who received postoperative chemotherapy at least 3 cycles, 4) age at diagnosis, after menarche ∼ < 40 years old, 5) available clinical information on menstrual resumption. Patients were divided into two groups according to the use of GnRHa during chemotherapy (GnRHa group and non-GnRHa group) and compared the incidence of early menopause.
Results
There was no difference in age, parity, menarche, stage, and type of operation (unilateral or bi-lateral adnexal surgery) among the two groups. The distribution of histology and types of chemotherapy drugs were different. After the end of chemotherapy, the resumption of menstruation was 100% in GnRHa group and 91% in non-GnRHa group (p = 0.0132). The univariate analysis of the factors affecting menstrual resumption showed that the use of GnRHa during chemotherapy was statistically significant difference (OR, 0.00 (0∼0.69;95% CI, p = 0.013).
Conclusions
The present findings provide evidence for the efficacy of temporary ovarian suppression with GnRHa during chemotherapy as an available option to reduce the likelihood of chemotherapy-induced ovarian insufficiency and potentially improve fertility in young patients with MOGCT.
