抄録

A 77-year-old man was referred to Honjo General Hospital for his asymptomatic hematuria. Bladder tumor was found in his urinary bladder. The screening of serum PSA level showed a gray zone data of 6.6ng/ml of EIKEN kit. No tumor was palpable on digital rectal examination and hypoechoic lesion was found on transrectal ultrasonography. Bladder tumor was resected transurethrally, and sextant systematic biopsy and hypoechoic directed biopsy were performed on his prostate. Bladder tumor was transitional cell carcinoma of grade 2, pT1b. Bladder instillation therapy was started. Moderately differentiated adenocarcinoma was exclusively found in the specimen obtained by hypoechoic directed biopsy. Hormonal therapy was started. Some discussion on primary double cancers, especially on bladder and prostate cancers, were made.
