[Clinical studies on 29 cases of testicular tumors]

Clinical studies were performed on 29 cases of testicular tumors over the past 16 years. There were 14 cases of seminoma (S), 4 cases of E+Teratoma (T), 1 case of embryonal carcinoma (E), 1 case of E+STGC, 1 of S+E+T, 1 of S+E+ yolk sac tumor (Y) +choriocarcinoma (C) +STGC, 1 of mature teratoma, 6 of non-germ cell tumor. The stage of the germ cell tumors were stage I in 13 cases and stage II A in one case among 14 cases of seminoma, and stage I in 3 cases, stage II A in 3 cases, stage II B in one case, stage III in one case among 8 cases of non-seminoma. All of the patients underwent high orchiectomy. The seminomas were treated by radiotherapy and non-seminoma cases mainly by chemotherapy after retroperitoneal lymph nodes dissection (RPLND). Twenty one of 23 cases have survived, excluding one death (E+STGC, stage II A) and one unclear case. High orchiectomy and radiotherapy are the established procedures for the treatment of stage I seminoma. The significance of RPLND should decrease because of the high efficacy of current chemotherapy in cases of stage I and II A non-seminoma.
