Simultaneous choriocarcinoma in mother and newborn infant.

A male infant, born following an uncomplicated pregnancy, was severely anaemic at birth following significant foeto-maternal haemorrhage. At three weeks of age a tumour was found in the liver with evidence of metastatic disease in the lungs. The infant died before treatment could be started. Postmortem revealed choriocarcinoma which led to subsequent diagnosis in the mother who also had pulmonary metastases. The mother has been successfully treated. The case is described in detail and followed by a discussion and a literature review of reported cases of simultaneous choriocarcinoma in infant and mother.

Single-agent methotrexate chemotherapy for the treatment of nonmetastatic gestational trophoblastic tumors.

OBJECTIVE: Our purpose was to evaluate the efficacy and toxicity of single-agent methotrexate chemotherapy and to identify factors associated with chemotherapy resistance in patients with nonmetastatic gestational trophoblastic tumors. STUDY DESIGN: A total of 337 patients with nonmetastatic gestational trophoblastic tumors (choriocarcinoma and invasive mole) received treatment at the Brewer Trophoblastic Disease Center of Northwestern University Medical School from 1962 through 1990. Of the 337 patients, 253 (75.0%) were treated initially with single-agent methotrexate 0.4 mg/kg intravenously daily for 5 days per treatment course repeated every 14 days. RESULTS: All 337 patients with nonmetastatic gestational trophoblastic tumors were cured. Of the 253 patients initially treated with methotrexate, resistance developed in 27 (10.7%), 22 (8.7%) required a second agent (actinomycin D), 3 (1.2%) required multiagent chemotherapy, and 2 (0.8%) had a hysterectomy to achieve complete remission. Factors associated with the development of resistance were pretreatment human chorionic gonadotropin level > or = 50,000 mlU/ml (36%, p < 0.001), nonmolar antecedent pregnancy (26%, p < 0.02), and clinicopathologic diagnosis of choriocarcinoma (20.5%, p = 0.02). Significant methotrexate toxicity requiring a change to a second agent occurred in only 12 patients (4.7%), the most common side effect being severe stomatitis. CONCLUSIONS: In a large series of patients with nonmetastatic gestational trophoblastic disease, single-agent methotrexate chemotherapy proved to be an extremely well-tolerated and effective treatment.
