RESUMO
OBJECTIVE: To analyze retrospectively the causes of death in gestational trophoblastic neoplasia (GTN) patients. The prognostic risk factors were also discussed. METHODS: One thousand one hundred and thirty GTN patients were hospitalized and treated at Peking Union Medical College Hospital from 1985 to 2004. Sixty-four of them died later and retrospective analyses were carried out on these patients. RESULTS: Fifty-eight out of the 64 patients died during initial treatment. The other six died from disease relapse and progression of the disease (PD). The major causes of death were multi-organ failure, intracranial haemorrhage, cerebral herniation, side-effects of chemotherapy, and PD after relapse. The result of multivariate analysis indicated the adverse prognostic factors included the interval between antecedent pregnancy and chemotherapy treatment (OR = 2.857, P < 0.01), the titer of beta subunit of human chorionic gonadotropin (beta-hCG, P < 0.05), the diagnosis of choriocarcinoma (OR = 3.635, P < 0.05), clinical stage (P < 0.05), multiple metastases (OR = 2.201, P < 0.01) and drug resistance (OR = 0.181, P < 0.01). CONCLUSIONS: A proper evaluation of a GTN patient before initial treatment is important. More attention should be paid to the death-related prognostic risk factors to improve the prognosis of high risk GTN patients.
