[A clinical study of 115 patients with testicular tumor]

One hundred and fifteen cases of testicular tumors treated at our Hospital between 1970 and 1989 were analyzed. The incidence of testicular tumors was 0.44% in the male outpatient department of our urological clinic. The age of these patients ranged from 6 months to 86 years (average: 31.7 years old) with two peaks in distribution; 0 to 5 and 21 to 45 years. Most of their chief complaints (77%) were painless swelling of scrotal contents. Location of the tumors included 56 in the right, 57 in the left and 2 on both sides. Histologically, there were 68 cases of seminoma, 10 cases each of embryonal carcinoma and teratoma, 22 cases of mixed type, 3 cases of malignant lymphoma and 2 cases of others. Stage of tumor was stage I in 69 cases, IIA in 25 cases, IIB in 8 cases and III in 13 cases. High orchiectomy was performed on all the patients. Radiotherapy, chemotherapy and retroperitoneal lymph node dissection were respectively done in 77, 42 and 16 cases. Seventeen patients died, and the 5-year survival rate calculated by the Kaplan-Meier method was 87.9% in seminoma and 68.9% in non-seminoma. The survival rate for the patients treated by chemotherapy including CDDP after 1983 was compared to those treated by other therapy before 1982. Between the two groups there was no significant difference.
