Staging error in the Bladder tumor: The correlation between stage of tur and cystectomy

Abstract

Objectives:Because tumor stage is very important in determining therapy, accurate sraging of bladder cancer must be estimated. For this aim, we examined the stage of TUR and compared it with the stage of cystectomy.Materials and methods:From 1992 to 1999, operations were performed on 127 patients with local invasive bladder cancer. Eight cases (74 male, 6 femle) underwent complete TUR of the tumor and then radical cystectomy. There was no residual macroscopic tumor after TUR in the bladder. The pathological staging of TUR and cystectomy were estimated and compared in these 80 cases. All pathologies were evaluated by the same pathology center.Results:There was correlation in only 20 patients (25%; 15 were T1, 5 were T2) while there was global error and discordance in 60 patients (75%). All of these 60 cases were overstaging in cystectomy specimens and downstaging was not found in any case. Fifty per cent of 10 T1 tumors were T1, while 50% were T3a;21.4% of T2 tumors were T2, 35.7% were T3a and 42.8% were T3b.Conclusions:The staging error of TUR in the bladder tumor may cause severe mistakes on deciding about radical surgery. However, although there was no understaging, which is more risky for false cystectomy indication, urologists must be careful about overstage/understage in the staging of TUR.
