ABSTRACT

Gestational trophoblastic neoplasia (GTN) is the term to describe a set of malignant placental diseases, including invasive mole, choriocarcinoma, placental site trophoblastic tumor and epithelioid trophoblastic tumor. Both invasive mole and choriocarcinoma respond well to chemotherapy, and cure rates are greater than 90%. Since the advent of chemotherapy, low-risk GTN has been treated with a single agent, usually methotrexate or actinomycin D. Cases of high-risk GTN, however, should be treated with multiagent chemotherapy, and the regimen usually selected is EMA-CO, which combines etoposide, methotrexate, actinomycin D, cyclophosphamide and vincristine. This study reviews the literature about GTN to discuss current knowledge about its diagnosis and treatment.


Neoplasia trofoblástica gestacional (NTG) é o termo que descreve o conjunto de anomalias malignas da placenta, incluindo a mola invasora, coriocarcinoma, tumor trofoblástico do sítio placentário e tumor trofoblástico epitelióide. Ambos a mola invasora e o coriocarcinoma respondem bem à quimioterapia, com taxas de cura superiores a 90%. Desde o advento da quimioterapia, NTG de baixo risco tem sido tratada com monoquimioterapia, pelo geral methotrexate ou actinomicina-D. Casos de NTG de alto risco, contudo, devem ser tratados com poliquimioterapia, e o regime usualmente escolhido é o EMA-CO que combina etoposide, methotrexate, actinomicina-D, ciclofosfamida e vincristina. Esse estudo revê a literatura sobre NTG a fim de discutir os conhecimentos atuais sobre seu diagnóstico e tratamento.
