Analysis of long-term effect of postoperative irradiation for testicular seminoma

Objective: To analysis the long-term effect and prognosis factors with postoperative irradiation in testicular seminoma.Methods: 96 patients were treated by surgery and radiotherapy after operation.There were 75 cases in stage Ⅰ,21 in stage Ⅱ.All of them were confirmed by pathology.The doses were given 26～40Gy in postoperation.Results: The survival in 5,10,15 and 20 years were 97.3% and 76.2%、 94.7% and 66.7%、 92.9% and 58.8%、 90.5% and 53.8% in stage Ⅰ and Ⅱ respectively（P＜0.001）.Conclusions: The testicular seminoma in postoperative should be radiated the lymphatic nodes of pelvic and abdominal cavity.We identify the stage of the primary tumor and doses of radiotherapy as important prognostic factor,and emphasize that surgery and postoperative radiotherapy will be the first choice of stage Ⅰand Ⅱ.
