Transurethral resection of bladder cancer with or without fluorescence

Abstract

Purpose of reviewTransurethral resection of bladder cancer (TURBT) is in its standard form an inherently imperfect technique. Fluorescence-guided photodynamic diagnosis (PDD) represents one way to improve the outcome by enhancing tumour detection. Fluorescence has been used in connection with bladder cancer since the 1970s, with a number of studies being published since then. However, the method is still not recommended as a standard part of TURBT mainly because of the limited level of evidence of concerned studies, questionable cost-effectiveness and even contradictory results. The review lists the latest articles covering this topic. Recent findingsSeveral recently published meta-analyses reviewed a series of randomized controlled trials (RCTs) concerning PDD assisted TURBT. Results were generally supporting the positive effect on reduction of recurrence rate. However, the mentioned meta-analyses are overlapping in terms of reviewed RCT that provide only a low level of evidence according to a recent Cochrane review. Supposed limitations of PDD (timing of the procedure, low specificity) and possible solutions are also covered.
