Effect of Intravesical Treatment of Transitional Cell Carcinoma With Bacillus Calmette-Guerin and Mitomycin C on Urinary Survivin Levels and Outcome
2003
ABSTRACTPurpose: Urine survivin is a predictive/prognostic molecular marker that detects transitional cell carcinoma (TCC) with high specificity and sensitivity. The presence of urine survivin in patients with TCC who receive intravesical instillation of bacillus Calmette-Guerin or mitomycin C may predict recurrence.Materials and Methods: Urine from 25 subjects receiving 27 intravesical treatments of bacillus Calmette-Guerin or mitomycin C for TCC were collected prior to, during and after treatment. Urinary survivin levels were compared with outcome, as assessed by cytology and cystoscopy with or without biopsy 1 month and up to 12 months after the completion of treatment.Results: Pretreatment survivin levels were higher in subjects in whom TCC recurred following treatment compared with those who achieved remission. Survivin levels increased several-fold during treatment with the highest survivin levels measured in subjects with recurrence. Median posttreatment values of survivin were zero in those who ac...
