A Study of Testis Cancer During 10Years

Testis cancer is a relatively rare cancer in men. Because testis cancer has not studied since long time ago in Mashad University of Medical Sciences, this study was performed. In our study testis cancer made 1.8%of all cancers in men. In this study 96 patient with testis cancer followed up. The peak incidence age of for seminoma was 20-40 years and for non-seminoma 20-30 years. In 66.5%of patients tumor was in right side and 33.5% in left. 14% of patients was cryptorchide. In 9^o tumor developed in cryptorchide testis and in 5% in contralateral testis, the average delay time frpm beginning of symptoms was 6 months. In our patients 91.5% of seminomas were classic and 9.5% anaplastic. Tow year survival in patient with testis tumor was 77% (89% in seminoma and 62% in non-seminoma). Five year survival in our patients was 69% (77% in seminoma and 60% in non-seminoma). The best result of therapy found in patients with non-seminoma who got RPLND (with 2 years survival of 100% and 5 year survival of 85%). This result maybe too low due to high stage of disease at the time of diagnosis.
