The tumor markers for malignant tumors arisen from urinary system including prostate cancer were reviewed. As for renal cell carcinoma there was no good marker used in routine test level at present. In the diagnosis of urothelial (transitional cell) carcinoma, mainly bladder cancer, 3 methods (urinary BTA, NMP22 and BFP) are used now in Japan. They all seem to be not fully sufficient in respect of the specificity. In foreign countries, new tests such as urinary telomerase and BLCA-4 are used and have been evaluated. On the diagnosis of prostate cancer, serum total PSA is well established and used. Various PSA relation markers have been advocated for the differentiation between benign prostate hypertrophy and carcinoma in so called "gray zone" level of total PSA. In methods based on the molecular forms of PSA, the ratio of free PSA to total PSA (f/T) is widely use, and proPSA is a test that is expected. Other approaches such as volume of index PSA, age specific PSA reference range and PSA velocity are also in practical application. Human glandular kallikrein 2, which belong to the human kallikrein family as well as PSA, is expected as a tumor specific marker.
