[Metastatic spread in various pathogenetic variants of choriocarcinoma].

The analysis of data on 208 cases of choriocarcinoma of different pathogenetic types established certain regularities of tumor dissemination into various organs. Metastases were observed in 33.3 +/- 5.1% of cases of choriocarcinoma of pathologic pregnancy. Dissemination was twice more frequent in patients suffering choriocarcinoma of normal (full-term or interrupted) pregnancy (56.2 +/- 4.5%; t = 3.4).
