title: [Testicular tumor in Mongolian men (report of 35 cases)].
abstract: OBJECTIVE
  To improve the diagnosis, therapy and prognosis of testicular tumor in Mongolian men.
  
  
  METHODS
  A retrospective review of 35 cases of testicular tumors in Mongolian men from seven medical centers dated from 1990 to 2004 was performed.
  
  
  RESULTS
  The usual presentation of a testicular tumor was a nodular or painless swelling of one gonad. The mean delay in diagnosis was 40.03 +/- 53.45 weeks. For 16 patients, delay in diagnosis was more than or equal to six months. The histologic composition of this series was 21 (60%) seminoma, 10 (28.6%) nonseminoma, 2 (5.7%) lymphoma, 1 (2.35%) fibroneuroma and 1 (2.35%) leiomyoma. Regarding stage, 22, 2, and 5 of 29 germ cell tumors were seen initially as stage I, II, and III, respectively. Combined therapy, including radical orchiectomy, radiotherapy and chemotherapy, were taken. 29 cases have been followed for 2 months to 10 years, 4 out of them died of distant metastasis, one died of other disease, one lives with tumor, the others live without relapse and metastasis. Three and 5-year survival rates for Mongolian patients with seminoma and nonseminoma were 95.0%, 95.0%, 57.1% and 42.8%, respectively.
  
  
  CONCLUSIONS
  In this article, the rate of seminoma to germ cell tumors is higher than that of general population. There is an increased mean delay in diagnosis for Mongolian patients. Three and 5-year survival rates for nonseminoma are lower than that for seminoma. Better public awareness regarding testicular tumor in this population, advances in diagnosis and therapy will help to improve therapeutic effectiveness and prognosis.
