[BTA tests in the diagnosis and follow-up of superficial bladder cancer]. / BTA tests in the diagnosis and follow-up of superficial bladder cancer.

We reviewed the literature on Bladder Tumor Antigen (BTA Trak and STat) tests to evaluate the usefulness of such tests in the diagnosis and follow-up of bladder cancer and to compare these tests to routine diagnostic tools. We also report our experience on BTA tests in monitoring tumor recurrence of superficial bladder cancer in 194 patients: a correlation between an augmented risk of tumor recurrence and serial measurements of BTA Trak and positive BTA Stat have been identified. According to the available data, BTA tests can be useful in the diagnosis and follow-up of superficial bladder cancer.
