[Chemotherapy in placental tumors].
Chemotherapy is a useful element, but not the only element, for controlling placental tumours. In cases of simple mole routine chemotherapy does not seem to be justified and usually, in 9 cases out of 10, it is useless. It is certainly not always effective and sometimes it may even be dangerous because of the development of chemoresistance. Invasive mole and tumours where a histological diagnosis has not been made and where there is no particularly unfavourable prognosis, usually heal with twice weekly methotrexate carried on for two months after cure has been confirmed clinically, radiologically and biologically. Choriocarcinomata and cases where histology has not been carried out but which have poor prognosis (extra-pulmonary metastases, numerous or large pulmonary metastases, long delay in treatment and the excretion of high levels of HCG) justify chemotherapy in which vincristine is followed by methotrexate or vincristine is followed by actinomycine D. For cure in these bad cases secondary surgery to remove residual lesions, either in the uterus or the lungs, may be necessary.
