【Abstract】 Testicular seminoma, though prone to lymphatic spread, is very radiosensitive. A high survival rate is expected by orchiectomy plus radiotherapy. 119 patients with testicular seminoma treated by radiotherapy in our institute from Jan. 1971 to Dec. 1982 are reported. All were confirmed by pathology. According to Boden and Maier’s Staging system, 81 (68%) patients were stage Ⅰ, 27 (23%) were stage Ⅱ and 11 (9%) stage Ⅲ. Survival rates were calculated by the life table method, The 5 and 10 year survivals were 98%, 98% for stage Ⅰ, 90%, 45% for stage Ⅱ and 55%, 0 % for stage Ⅲ respectively. The differences between the survivals of stage Ⅰ, Ⅱ and Ⅲ were of statistical significance. Due to the fact that distant metastasis is the chief cause of death, we suppose the advanced lesions might benefit from adjutant chemotherapy. Patients with localized metastases outside the irradiated area could be managed with extended radiation. Postoperative radiotherapy with an optimum dose of about 25-35 Gy/3-4 weeks for testicular seminoma is recommended.更多还原
