Dysgerminoma: a review of 158 cases from the Emil Novak Ovarian Tumor Registry.

One hundred and fifty-eight dysgerminomas from the Emil Novak Ovarian Tumor Registry and the Gynecologic Pathology Laboratory of The Johns Hopkins Hospital were reviewed. Five-year follow-up was available for 82% and 10-year follow-up was available for 65%, with survival rates of 83% and 74% for pure tumors, respectively. Survival was related to stage of disease and presence of other germ cell elements. Patients treated by unilateral adnexectomy alone for stage IA pure dysgerminoma had a 95% 5-year survival. Survival of these patients was not affected by tumor size.
