title: [Factors of severity in placental choriocarcinoma].
abstract: A retrospective study has been carried out on the poor prognostic features of a group of 57 patients. These are: the existence of extra-pelvic and extra-pulmonary metastases and a level of serum HCG above 200000. The most favourable prognostic signs are absence of these two factors in pregnancy that is not normal and a delay between the onset of the first diagnostic elements and treatment of less than 6 months.
