[Factors affecting late treatment results with uterine choriocarcinoma patients].

Factors influencing posttreatment survival of uterine choriocarcinoma patients were studied in 166 cases of histologically-verified tumor. Procedures for calculating indexes of actual survival as well as tabulated rates of 3- and 5-year survival are presented. A 3-year period of follow-up appeared to be sufficient for evaluation of prognosis. The following factors proved to be of the highest prognostic value: the outcome of preceding pregnancy, duration of latent and symptom periods, peripheral blood count, parametrial involvement, changes of chorionic gonadotropin level in the course of treatment, site of metastasis and cytostatic drugs used.
