Neo-adjuvant chemotherapy in the treatment of advanced malignant germ cell tumors of ovary

Objective: In order to preserve fertility, we attempted neo-adjuvant chemotherapy (NACT) in patients of malignant ovarian germ cell tumor (MOGCT) with advance and bulky disease. Patients and Methods: Between January 1988 and December 2009, 23 patients received NACT. Patient's median age was 19 years, ranging from 14 to 28 years. FIGO stages III - 20 and IV - 3. Histology subtypes were: dysgerminoma, n = 14, mixed GCT, n = 6 and 3 had endodermal sinus tumor. Patients were planned for four cycles of BEP (bleomycin, etoposide and cisplatin) chemotherapy followed by fertility sparing surgery (unilateral salpingo-oophorectomy + omentectomy ± lymphadenectomy). Results: Following NACT - 21 patients responded; complete (CR) - 16 and partial response (PR) - 5. One patient progressed and another was lost to follow-up after 2 cycles. 18 of 21 responders underwent surgery; 13/18 had pathological CR, 5/18 had residual disease and achieved CR following 2 more cycles of BEP. 3 patients refused for surgery; 2 relapsed at 9 and 12 months, and achieved second CR following salvage chemotherapy and surgery, third patient continues to be disease-free. Currently, 21 of 23 patients are alive and disease-free at a median follow-up of 74 months. 18/21 patients have resumed menstruation and 10 eligible patients have delivered 13 full term healthy babies. These results are comparable to patients with advanced disease (n = 43) treated with standard approach (initial surgery and adjuvant chemotherapy) during the same period. Conclusion: NACT followed by fertility sparing surgery could be a reasonable option for patients of advanced MOGCT, not suitable for optimal cyto-reduction
