title: Urinary markers of malignancy.
abstract: Transitional cell carcinoma (TCC) is the second most common malignancy in the genitourinary tract. The majority of urothelial tumors are superficial when the patient first presents, but despite adequate resection of the primary lesion the recurrence rate is particularly high. In a small but significant group of patients the tumor is primary invasive or subsequently can progress and leads to death. Voided urine can be easily obtained and therefore diagnostic urine tests would be ideal for screening or follow up of TCC. Although many urinary markers have been described, none of them is used routinely in clinical practice. Promising tumor markers still need to be evaluated in multi-center clinical studies. Larger prospective trials are necessary in order to identify prognostic indicators that would help to predict disease progression or response to different treatment modalities (BCG, chemo-, radiotherapy, etc.). Hopefully, new diagnostic urine tests will allow to identify patients who will most benefit from early cystectomy with or without adjuvant treatment, bladder sparing protocols or systemic treatment. In this paper we have reviewed the literature and discuss, from the clinician's point of view, the current status of various diagnostic tests for urinary markers.
