ABSTRACT

From 1974 to 1989, 17 dysgerminomas of the ovary were treated at the Centre Claudius Regaud. The mean age of the patients was 21 years 53% were FIGO stage IA, 17% were stage IB, 6% were stage IIB and 24% were stage IIIC. Conservative surgery was performed in 13 patients (unilateral salpingo-oophorectomy) and non-conservative surgery was performed in the others patients. 70% of the patients underwent complete resection. Post-operative treatment was administered in every case but one (radiotherapy 15 patients; combined chemo-radiotherapy 1 patient). All patients achieved complete remission after the first-line treatment, but 2 of them recurred (1 IA, 1 IIB). A second remission was achieved in both cases. The overall survival rates were 100% at 2 years, 94% at 5 years and 89% at 10 years. The dual objective of curing the patient of her malignant disease while preserving her reproductive function was achieved in 53% of the patients.
