title: Pure immature teratoma of the ovary: analysis of 22 cases.
abstract: Between 1970 and 1991, 22 patients with pure immature teratoma were treated at the Center of Oncology in Krakow. Sixteen (72.7%) patients had stage I, four (18.2%) stage II, and two (9.1%) stage III of disease, nine (40.9%) patients had grade 1, 11 (50%) grade 2, and two (9.1%) grade 3 tumors. Eight stage Ia, grade 1 patients were treated with surgery only, the remaining 14 (63.6%) received postoperative chemotherapy. Five-year NED (no evidence of disease) survival was achieved in 81.8% of patients. Out of 16 stage I patients, 15 (93.8%) survived 5-year NED, out of six stage II and III, three (50%) patients only survived this period. We cured all grade 1 patients, and 81.8% (9/11) grade 2; two grade 3 patients died because of tumors. We also cured all six stage Ia patients, treated with unilateral salpingo-oophorectomy (with or without chemotherapy), and all eight stage Ia grade 1 patients treated with surgery only.
