OBJECTIVES: To evaluate variations on the serum PSA levels during and after administration of intravesical BCG and its relationship with previous transurethral resection of the prostate (TURP). METHODS: PSA serum concentration variations were studied after each instillation, at 1 month and at 3 months in 24 patients with superficial bladder cancer and/or CIS under weekly BCG instillations treatment. Three patients had undergone TURP. RESULTS: A raise in PSA was observed in 87.5% of the cases during BCG instillations, although the increase was only significative in patients who had undergone TURP. PSA values descended at one and three months. CONCLUSIONS: Endovesical BCG administration produces an increase on serum PSA levels. This variation is higher in patients with history of TURP.
