Abstract
The treatment strategy for non-muscle invasive bladder cancer (NMIBC) has not changed significantly over the past 30 years. Chemotherapeutic agents (mitomycin-C, epirubicin, etc.) and BCG (Bacillus Calmette-Guerin) immunotherapy are used as adjuvant intravesical therapy. To compare the difference between adjuvant chemotherapy and adjuvant immunotherapy in their efficacy of reducing the number of tumor recurrences. In this prospective clinical study, which included 99 patients with NMIBC from March 2018.-March 2023., we publish the results for all risk groups of patients treated with intravesical chemotherapy Epirubicin or with BCG immunotherapy, after TURBT (Trans urethral resection of bladder tumor) within 1 year. Patients were stratified into 2 groups. The first group was treated with Epirubicin (1 dose within 24 hours of surgery, then 6 weekly instillations and 3 maintenance doses), and the second group was treated with BCG (2-3 weeks after TURBT 6 weekly instillations, and 3 maintenance doses). The monitoring period was 24 months. In patients treated with intravesical chemotherapy, recurrence occurred in 9 patients (17.64%), and in patients treated with BCG, recurrence occurred in 7 patients (14.58%). A similar incidence of disease recurrence was observed in both groups (p=0.787). The results of our study show a similar therapeutic response by risk groups of patients treated with chemotherapy and immunotherapy. Since BCG production will cease in the future, the task of urologists is to introduce intravesical chemotherapy into wider use and to modernize it as a safe and effective method of adjuvant treatment for non-muscle-invasive bladder cancer.
