Abstract
invasive cancer of the urinary bladder (ICUB). The examination
complex included clinical, laboratory, radiation tests, endoscopic and
morphological investigations of the surgical material. The patients received
four types of treatment: transurethral resection (TUR) of the
bladder wall (n = 102) alone; TUR+MVAC chemotherapy (n = 56);
open resection of the urinary bladder only (n = 38); open resection+MVAC
chemotherapy (n = 28). In diagnosis of papillary lesions
sensitivity of cystoscopy (CS) was 66.6%, fluorescent CS (FCS) -95.2%.
Sensitivity in diagnosis of squamous tumors was 33.3 and
91.6%, respectively. The best results were achieved in patients with
pT2A tumor invasion depth, Gl differentiation of tumor cells after
TUR with adjuvant polychemotherapy (PCT) recurrences in these
patients arose by 41.2% less frequently than in patients after TUR only,
5-year survival in patients after TUR+PCT was 83.3%. Thus, FCS
improves diagnosis of urinary bladder tumors (sensitivity of CS was
70.0% vs that of FCS - 95.0%). In cancer of the urinary bladder the
organ can be saved only at stage pT2Gl. A method of choice is TUR
of the bladder wall with adjuvant PCT.
Key words: cancer of the urinary bladder, fluorescent cystoscopy,
transurethral electroresection of the urinary bladder, open resection
of the urinary bladder
