title: [Clinical analysis of 17 cases of nongestational choriocarcinoma].
abstract: OBJECTIVE
  To evaluate the diagnosis, treatment and prognosis of nongestational choriocarcinoma.
  
  
  METHODS
  Retrospective analysis was done on 17 cases (11 female patients and 6 male patients) of nongestational choriocarcinoma treated in Peking Union Medical College Hospital from 1985 to 2001.
  
  
  RESULTS
  All cases received operation as well as chemotherapy. The mean courses of chemotherapy for each patient is 8.6. Correct diagnosis at the first administration was seen in only 3 cases. Nine female and 2 male patients obtained complete remission after the treatment and no recurrence was seen during the 8 to 118 months of follow up.
  
  
  CONCLUSIONS
  The diagnosis of nongestational choriocarcinoma is expected to be promoted. Optimal prognosis can be gained for the female patients after treatment by operation as well as chemotherapy, but the prognosis for the male patients is poor.
