“…In the present study, there was a striking association of seminoma with subsequent renal cell cancer, and curiously, in group B of the present investigation, there were 2 more renal carcinomas preceding seminoma. This association was also found in the largest series of second tumors after testicular cancer [6]and in several other reports, and testicular malignancies were the majority of these seminomas [36, 44, 45, 46, 47, 48, 49, 50, 51]. Other studies, however, failed to find a significantly increased occurrence of renal tumors in cohorts of testicular cancer patients [4, 5, 35, 52].…”
