Chemotherapy of Choriocarcinoma.

Abstract

The department of Gynecology and Obstetrics of Florence University reports the following findings for the chemotherapy of gestational choriocarcinoma daring the period 1962–74. Sixteen cases, 11 of which were rated high risk cases, were given chemotherapy with MTX alone or in association with other cytotoxic agents. In the 12 surviving cases that may be considered the incidence of complete remission (from 4 to 13 years) is 67 %. Of the 8 cases rated as cured 3 were high risk cases at the beginning of treatment. Intermittent chemotherapy with MTX only was given by slow intravenous injection at doses of 3 to 4 mg/kg for 24–48 h followed from the 48th h by folinic acid treatment for 1–2 days. This schedule is recommended because of its negligible toxicity as a replacemen for intramuscular MTX in 5-day courses, which carries a fairly high risk of toxicity.
