Definite total radical resection in treatment of patients, suffering low-differentiated cancer of the bladder
Objective. To determine the operative volume of surgical treatment in total radical resection of the bladder in autonomous regime and to estimate the survival indices in patients with low-differentiated cancer of the bladder depending on time of conduction of radical total resection of the bladder.
Materials and methods. Retrospectively 522 histories of the diseases were analyzed in the patients with diagnosis of low-differentiated cancer of the bladder, including 190, in whom radical total resection of the bladder was performed in 1998 - 2016 yrs period. The survival indices were determined. Using Kaplan-Meier method, comparative analysis of the survival indices in patients was done, to whom radical total resection or salvage resection of the bladder performed.
Results. Total radical resection of the bladder in autonomous regime was done in 24.7% patients with low-differentiated cancer of the bladder or in 67.9% patients, to whom total resection of the bladder was performed. The indices of total 3-, 5- and 10-yr survival of the patients have constituted 96, 93 and 45%, accordingly. The survival indices in the patients after organ-preserving treatment and further salvage total resection of the bladder for locally progression of cancer were better, than in the patients, to whom the treatment consisted of primary radical total resection of the bladder, but the difference have appeared statistically nonsignificant (p=0.286). Average period between conduction of organ-preserving treatment and salvage total resection of the bladder have constituted 34 mo.
Conclusion. Radical total resection of the bladder in autonomous regime constitutes the extended method of treatment of muscularly-invaded low-differentiated cancer of the bladder (performed in 24.7% of all the patients) and guarantees satisfactory late follow-up results while primary or postponed performance.
