title: [Ovulation induction therapy and malignant ovarian cancer].
abstract: In the authors' institute 1097 patients received treatment for ovarian cancer between the 1st of January, 1960 and the 31st of December, 1997. 92 of them had malignant granulosa cell tumor. In this study the link between ovulation induction therapy and ovarian cancer was analyzed with retrospective questionnaire. 236 questionnaires were shared out among patients with malignant ovarian tumor, who were treated between 1990 and 1997. 7 of 113 patients, who gave correct answers to the questions (6.2%) received ovulation induction therapy. Epithelial ovarian cancer developed in 2 of the cases during, and in 5 cases just 6-16 years after the clomiphene-citrate treatment. None of the 45 patients with granulosa cell tumors received induction therapy. The number of patients admitted because of malignant ovarian tumor before and after the induction therapy was also compared. There was no significant increase in the occurrence of the malignancy. Since 1986 in the in vitro fertilization program of the clinic nearly 1,500 patients were treated with effected ovulation induction drugs causing superovulation. The authors don't know of any development of malignant ovarian tumor, and 732 woman have confirmed this fact. The number of patients deceased in consequence of ovarian cancer in different age groups, and the distribution of the women population in every age group in Hungary, from the year of 1979 was also analyzed. There was no significant increase found in the number of deceased among the studied age groups, moreover a significant decrease among them could be observed. The link between ovulation induction therapy and ovarian cancer can neither be strengthen, nor deny by the result of the study, however the close relationship which seemed to be logical can be queried. To give an exact answer for the question a vast, long-term, prospective of retrospective follow-up case-control study is needed.
