Immature teratoma of the ovary.

Results of treatment of 9 cases of pure immature teratoma of the ovary seen at the University Hospital, Kuala Lumpur, are presented. Six patients were in Stage 1 and three in Stage 3. A majority of them had grade 2 or 3 tumors. Four patients in Stage 1 had the conservative surgery of salpingo-oophorectomy performed, the more radical procedure of total hysterectomy, bilateral salpingo-oophorectomy omentectomy, and tumor debulking where feasible being carried out in the others. Adjuvant chemotherapy consisted of either pulsed cyclophosphamide, VAC (vincristine, actinomycin D, and cyclophosphamide) or PVB (cis-platinum, vinblastine, bleomycin) regimes. Seven patients have survived for periods up to 9 years with no clinical evidence of disease.
