title: Risk factors in gestational trophoblastic disease, and consequences for primary treatment.
abstract: Treatment with methotrexate (MTX) for two patients with gestational choriocarcinoma proved to be inadequate; subsequently both patients received a combination of cis-platinum, cyclophosphamide, actinomycin D and etoposide. These histories demonstrate the need for better prediction of the efficacy of MTX treatment. Baghshawe and Goldstein developed scoring systems to recognize patients requiring primary combination chemotherapy. The Dutch Working Group for Trophoblastic Tumors recently introduced a simplified scoring system to classify these patients. In order to compare these three scoring systems to predict the effect of primary treatment with MTX a retrospective study was made of 37 patients. MTX treatment failures were predictable in 8 out of 13 patients using Bagshawe's system and 6 out of 13 by the Dutch scoring system. The specificity was 88 and 92%, respectively. Goldstein's scoring system proved to be the least sensitive, but very specific.
