Abstract
Purpose: From 1956 to 1986, we have retrospectively studied 184 patien ts with a Stage I testis seminoma treated by orchidectomy and radiothe rapy at the Institut Gustave Roussy. Methods and Materials: The 184 pa tients received adjuvant radiotherapy to the para-aortic and ipsilater al iliac nodes. Of the 184 patients, 133 received additional mediastin al and supraclavicular irradiation, 47 received supraclavicular withou t mediastinum irradiation, 98 patients received additional radiotherap y given to inguino-scrotal area. The mean dose of irradiation is 21 Gy which is the lowest dose published. The actuarial survival rate is, r espectively, 96%, 93%, 83% and 77% at 5, 10, 15, and 20 years. Results : Four patients relapsed, and four died of progressive disease. Four p atients presented cardiovascular disease, all of them had mediastinal irradiation, two were heavy smokers. Seventeen second malignancies wer e observed, six tumors in the controlateral testis. The actuarial risk of developing a second malignancy is 10% at 10 years, 21% at 20 years . The cure rate and relapse rate in our patients is the same as that o btained by higher dosage of irradiation. Conclusion: We conclude that low dose of prophylactic irradiation in lombo aortic and ipsilateral i liac lymph nodes is active and safe in the treatment of Stage I testis seminoma.
