Diag nostic curettage is helptul to diagnosis for the patients with vagina bloedy discharge preoperativeIy, the success rate is 71 %. But it was insignificance in the patients without these symptoms. The prognosis of the tumor was poor, which 12 of 29 patients died within two years, only 7 of 29 patients lived more than five years.
