고환종양: 20년 치료경험

Abstract

Forty-six patients with testicular tumor were treated at our hospital From 1971 to 1990. There were 25 children( 13 yolk sac tumors, 10 teratomas, 1 teratocarcinoma and 1 acute lymphocytic leukemia) and 21 adults(11 seminomas, 4 non-seminomatous germ cell tumors and 6 non-germ cell tumors). Testicular lumors with clinical evidence of cryptorchidism were 4 seminomas and 2 non seminomts. Serum AFP or HCG were observed in 8 patients of 8 seminomas, 1 of 5 teratomas, 7 of 9 yolk sac tumors and 4 or 5 non-seminomatous germ cell tumors(NSGCT). Four stage 1 seminomas and 1 NSGCT were tumor free of 2 years after radical orchiectomy and 2 of 4 seminomas were received prophylactic radiotherapy. Two stage II seminomas and 1 NSGCF treated with PVB nomas and radiotherapy were tumor free of 2 years but stage III seminomas and NSGCT died during chemotherapy. All stage 1 yolk sac tumors and teratomas were tumor Free of 2 years by surveillance only following radical orchiectomy but stage II and III yolk sac tumors died during chemotherapy. We have suggested that poor result of stage III testicular tumors can be attributed to few cases with more aggressive and more toxic chemotherapy in the unfavorable prognosis disease(advanced extent) and poor compliance of patient of therapy. Key word : Testis, Tumor.
