OBJECTIVE: To evaluate the results obtained with adyuvant radiotherapy. METHODS: We analyzed 40 clinic histories of testis cancer stage I diagnosed patients were studied. All of them received adyuvant radiotherapy between April 1992 and May 2004. The most common histological type was seminoma. The diagnosis and the staging were done through testicular ultrasound, serum tumor markers determination, abdomen and pelvis CT, and chest Rx films. The patients were treated with Cobalto 60 unit and linear accelerator of 6 Mev of photons. Volume: Para-aortic and paracaval lymph node region and ipsilateral illiac node region vs. para-aortic and paracaval lymph node region only. Daily dose: 1.8 Gy total doses 30.6 Gy. Followup was done during 3 years with chest Rx and abdomen and pelvis CT at 12 months, and a whole clinic check-up once a year. RESULTS: Recurrence rate in ipsilateral iliac nodes (0 % vs. 6.25 %) distance progression (8.3 % vs. 0%) and global survival (100 % vs. 100 %) in three years follow-up was established. CONCLUSION: Our results are similar to the ones published in world literature. Bearing in mind the scarce number of patients, changes in global survival were not shown when radiotherapy in ipsilateral illiac nodes was added. Radiation therapy in para-aortic and paracaval lympth nodes is the standard treatment, there is being necessary to optimize the radiotherapy modality with other radiation therapy techniques: In three dimension and modulated intensity to diminish the long term toxicity.
