OBJECTIVE: There is no consensus regarding the best interval time between transurethral resection of a bladder tumor and Bacillus Calmette-Guerin (BCG) perfusion. This study was to explore whether the interval time has an impact on the prognosis and adverse effects.
METHODS: We retrospectively reviewed the clinical data of patients who received BCG intravesical perfusion at Sun Yat-sen University Cancer Center (SYSUCC) from September 2015 to October 2021. Recurrence-free survival (RFS) and progression-free survival were the primary endpoints. Cox regression was used to explore independent predictors. The association between interval time and adverse effect grade was detected by logistic regression. Propensity score matching (PSM) was performed.
RESULTS: A total of 403 patients were enrolled, the median interval time was 24 days (6-163 days), and the follow-up was 28 months (7-82 months). Eighty-eight (20.9%) patients relapsed, and 40 patients (10.0%) suffered progression. The multivariate Cox regression analysis confirmed that interval time was an independent predictor of RFS (p = 0.017). Notably, when the interval time was less than or equal to 26 days, there was a trend toward better RFS, PSM resulted in 65 matched pairs in each group, and Kaplan-Meier analysis showed that there was a significant difference in RFS between groups (p = 0.009). The logistic regression analysis showed that there was no correlation between interval time and adverse effects and their grades (p > 0.05).
CONCLUSIONS: We considered that the first BCG perfusion could be performed within 2-4 weeks after surgery.
