Germ cell tumors of the ovary: Is there a role for aggressive cytoreductive surgery for nondysgerminomatous tumors?

Abstract. Bafna UD, Umadevi K, Kumaran C, Nagarathna DS, Shashikala P, Tanseem R. Germ cell tumors of the ovary: Is there a role for aggressive cytoreductive surgery for nondysgerminomatous tumors? Thirty-three patients with germ cell tumor of the ovary were seen at Kidwai Memorial Institute of Oncology (KMIO), Bangalore, between 1996 and 1999. Twelve patients had endodermal sinus tumor (EST), 11 dysgerminoma, seven mixed germ cell tumor, and three immature teratoma. Thirteen patients had bulky residual disease of>10 cm after the primary surgery. All but one patient received a combination of bleomycin, etoposide, and cisplatin (BEP) either as neoadjuvant (NACT, 3 cases) or as adjuvant therapy (28 cases). In the present study, all 11 patients with dysgerminoma achieved sustained complete remission (CR), irrespective of the size of residual disease at the time of chemotherapy. Four out of six cases (66.6%) with bulky nondysgerminomatous tumor achieved CR, which was sustained in three cases and one recurred. Fifteen of the remaining 16 (93.7%) nonbulky, nondysgerminomatous tumors achieved CR, which was sustained in 14 cases and recurred in one. This study indicates that there may be a role for aggressive cytoreductive surgery, either primary/interval or at the time of second-look laparotomy, in selected patients with nondysgerminomatous germ cell tumor of the ovary.
