OBJECTIVETo improve the diagnosis and treatment of testicular tumor.

METHODSEighty-seven cases of testicular tumor were retrospectively studied.

RESULTSOf the total number, 79 cases were pathologically diagnosed as germ cell tumor (90.1%), among which there were 44 cases of seminoma (55.7%) and 7 cases of benign tumor (8.1%). Nonseminoma germ cell tumor (NSGCT) was found mainly among those under 5 and from 18 to 40 years of age, while seminoma chiefly among those beyond 17, and testis tumor was rare among those between 5 and 17 years old (1 case only). Three-year and 5-year survival rates of seminoma and NSGCT were 90.6% and 81.3%, and 83.3% and 56.7%, respectively.

CONCLUSION(1) Testicular tumors are mostly germ cell tumors. (2) NSGCT develops mainly among those under the age of 5 and from 18 to 40. (3) Seminoma is rare in those under 18. (4) Testicular tumor rarely develops among those between 5 and 17 years old. (5)Three-year and 5-year survival rates for seminoma are higher than those for NSGCT.
