[Long-term follow-up of the ovarian malignant teratoma].
Sixty-six patients with ovarian malignant teratoma have been treated in our hospital from Jan. 1954 to Dec. 1990. Two histological types were covered: (1) some malignant tissue came from mature teratoma; (2) embryonic tissue immature ovarian teratoma. During the process of long-term follow up, 38 cases survived, 28 died. With life table calculation, the 5, 10, 15, 20, 25 and 30 year survival rates of the malignant teratoma were 61.5 +/- 6.1; 57.8 +/- 6.2; 57.8 +/- 6.2; 52.8 +/- 7.4; 52.8 +/- 7.4; and 52.8 +/- 7.4%, respectively. The prognosis was related to the age of patient, the size of the tumor, the histological grade and especially, to the clinical staging. The treatment method of this teratoma was discussed as well.
