Abstract
Aim. To evaluate the treatment outcomes of patients with non-muscle invasive bladder cancer by using transurethral resection alone, transurethral resection combined with electrovaporization and transurethral resection with preliminary tumor fulguration.
Methods. The analysis of the treatment outcomes of 81 patients with non-muscle invasive bladder cancer (¬Ta–T1N0M0) in the urological clinic of Kazan State Medical University between the period 2000 and 2016 was carried out. The mean age was 63±10.8 years. The patients were divided into 3 groups. The first group included 28 patients who underwent transurethral resection as monotherapy, the second group — 26 patients underwent transurethral resection combined with electrovaporization, and the third group — 27 patients underwent transurethral resection with preliminary tumor fulguration.
Results. In the group of patients who underwent transurethral resection only, recurrences outside the resection zone occurred in 8 (28.57%) patients, recurrences in the resection zone were detected in 6 (21.43%) patients, and tumor progression was diagnosed in 3 (10.71%) patients. In the group of patients who underwent transurethral resection combined with vaporization, recurrences outside the resection zone were diagnosed in 6 (23.08%) patients, recurrences in the resection zone were detected in 4 (15.38%) cases, and tumor progression was detected in 2 (7.69%) patients. In the group of patients who underwent transurethral resection with preliminary tumor fulguration, recurrences outside the resection zone were diagnosed in 4 (14.81%) patients, in the resection zone — in 6 (22.22%) patients, tumor progression in 2 (7.41%) cases.
Conclusion. Transurethral resection alone is not a radical treatment of non-muscle-invasive bladder cancer; transurethral resection combined with vaporization slightly increases the radicality of treatment; transurethral resection with preliminary fulguration reduces the recurrence rate, ensuring the prevention of implant recurrence.
