PREVENTION OF RECURRENCE AFTER ORGAN-SAVING SURGERY OF PATIENTS WITH MUSCLE-INVASIVE BLADDER CANCER

Abstract

The article represents the study of survival rate (common, oncology-specific, disease-free) and frequency and nature of the recurrence after organ-saving surgery of patients with muscleinvasive bladder cancer stages T2b and T3aN0M0G1-G3 with full diagnosis of bladder mucosa, the adjuvant intravesical chemotherapy on pre-operative stage. Oncology-speсific and diseasefree survival 5-year rates with full diagnosis of bladder mucosa, the adjuvant intravesical chemotherapy on pre-operative stage were higher. Recurrence of bladder cancer were on the fields, other than the zones of operations, the stages of disease were lower than that of the original tumor. These factors indicated the presence of an unrecognized cancer in situ on the walls of the urine bladder
