ABSTRACT
Objective:
To investigate the clinical outcomes of neoadjuvant chemotherapy with Gemcitabine and Cisplatin (GC) for muscle-invasive bladder cancer (MIBC).Methods:
Retrospective analysis of 67 MIBC patients admitted to Beijing Friendship Hospital, Capital Medical University from December 2010 to June 2020. Fifty-five MIBC patients (cT2-T4aN0M0) underwent GC plus radical cystectomy-pelvic lymph node dissection. Pathological responses, prognosis and chemotherapy toxicities were analyzed. The Chi-square test and Fisher′s exact probability method were used to compare the count data between groups. The overall survival (OS) and disease-free survival (DFS) were based on the Kaplan-Meier survival curve, and the Log-rank test was used to evaluate the difference between groups in the survival curve. Prognostic analysis adopts Cox proportional hazards regression model.Results:
Fifty-five MIBC patients received GC plus radical cystectomy-pelvic lymph node dissection. The 81.8% patients ( n=45) received 2 cycles GC and 18.2% patients ( n=10) received 3 cycles. The complete pathological response (pT0N0M0) rate was 30.9% ( n=17) and partial response (pT 1/Tis/T aN 0M 0) rate was 10.9% ( n=6). Overall pathological response rate was 41.8%. The median follow-up was (47.0±37.7) months, 5-year OS were 82.2% and 22.1% (<pT 2 versus ≥pT 2, P<0.001), and DFS were 86.1% and 32.1% (<pT 2 versus ≥pT 2, P<0.001). Pathological response and positive lymph nodes were independent risk factors of overall survival and disease-free survival on multivariable analysis ( P<0.05). The most common chemotherapy toxicities were hematologic toxicities and gastrointestinal reactions, and none delayed surgery due to toxicities.Conclusion:
Neoadjuvant GC plus radical cystectomy-pelvic lymph node dissection has a significant clinical benefit in MIBC patents and chemotherapy toxicities are well tolerated.
