title: [Analysis of death causes of gestational trophoblastic neoplasia patients].
abstract: 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.
