Objectives. To compare pathologic outcomes after treatment with gemcitabine and cisplatin (GC) versus methotrexate, vinblastine, adriamycin, and cisplatin (MVAC) in the neoadjuvant setting.Methods. Data was retrospectively collected on 178 patients with T2-T4 bladder cancer who underwent radical cystectomy between 2003 and 2011. Outcomes of interest included those with complete response (pT0) and any response (≤pT1). Odds ratios were calculated using multivariate logistic regression.Results. Compared to those who did not receive neoadjuvant chemotherapy, there were more patients with complete response (28% versus 9%, OR 3.11 (95% CI: 1.45–6.64),P=0.03) and any response (52% versus 25%, OR 3.23 (95% CI: 1.21–8.64),P=0.01). Seventy-two patients received GC (n=41) or MVAC (n=31). CR was achieved in 29% and 22% of GC and MVAC patients, respectively (multivariate OR 0.39, 95% CI 0.10–1.58). Any response (≤pT1) was achieved in 56% of GC and 45% of MVAC patients (multivariate OR 0.45, 95% CI 0.12–1.71).Conclusions. We observed similar pathologic response rates for GC and MVAC neoadjuvant chemotherapy in this cohort of patients with muscle invasive urothelial cancer (MIBC). Our findings support the use of GC as an alternative regimen in the neoadjuvant setting.

267 Background: Neoadjuvant chemotherapy for muscle invasive urothelial carcinoma (UC) of the bladder is associated with higher rates of pathologic complete response (CR) and improved disease-specific survival compared to those treated with radical cystectomy (RC) alone. Two standard regimens used are (1) gemcitabine and cisplatin (GC); and (2) methotrexate, vinblastine, adriamycin, and cisplatin (MVAC), with debate on whether there is a difference in clinical efficacy. In this analysis, we compare the pathologic outcomes at cystectomy between neoadjuvant GC and MVAC treatment. Methods: Data was retrospectively collected on patients with T2-T4 UC of the bladder who underwent RC between Sept 2003 and December 2011 at the University of Washington. Clinical and pathologic factors were recorded along with neoadjuvant chemotherapy and comorbidities. Pathologic outcomes included those with CR (pT0) and near CR (nCR = pT0/Ta/Tis). Odds ratio (OR) for CR and nCR were calculated using multivariate logistic regression adjusting for demographic (age, gender, race), medical (creatinine, diabetes mellitus, cardiac disease) and clinical factors (clinical T stage, prior BCG therapy, complete tumor debulking prior to chemotherapy). Results: A total of 78 patients received GC or MVAC neoadjuvant chemotherapy followed by RC, including 46 who received GC and 32 who received MVAC. There was no difference in gender, renal function, cardiac disease or clinical stage between the two groups. Patients over 70 years of age primarily received GC (17/18). CR was achieved in 30% and 25% (p = 0.15) of GC and MVAC patients, respectively (multivariate OR 0.42, 95% CI 0.11-1.63). nCR was more common in those receiving GC (50% vs. 38%, p = 0.04) although non-significant in the multivariate model (OR 0.30, 95% CI 0.07-1.16). Conclusions: We observed similar pathologic response rates for GC and MVAC neoadjuvant chemotherapy in this cohort of bladder cancer patients. These observations support the use of GC as an alternative regimen in the neoadjuvant setting.

The advent of immune checkpoint inhibitors (ICIs) has changed the game in cancer immunotherapy, specifically in the treatment of urothelial bladder cancer. Several clinical trials combining chemotherapy with ICIs have resulted in approvals from the FDA and subsequent revisions within the NCCN Guidelines. The current NCCN Guidelines for Bladder Cancer reflect the most up-to-date, evidence-based data relating to the evaluation and management of urothelial bladder cancer. ICIs have been incorporated into the guidelines as maintenance therapy in response to chemotherapy, sequencing after disease progression from frontline chemotherapy, and for the treatment of non–muscle-invasive bladder cancer.
