Neoadjuvant Dose-dense Gemcitabine and Cisplatin in Muscle-invasive Bladder Cancer: Results of a Phase 2 Trial
Eur Urol Oncol (2018) 1:54-60.
Abstract
Background: Accelerated (also termed dose-dense, DD) chemotherapy regimens such as accelerated methotrexate, vinblastine, doxorubicin, and cisplatin have shown better efficacy and tolerability in the metastatic setting, and shortened the time to surgery in the neoadjuvant setting compared to standard-schedule regimens. We hypothesized that a DD schedule of gemcitabine and cisplatin (GC) would shorten the time to surgery and yield similar pathologic complete response rates (pT0) in patients with muscle-invasive bladder cancer (MIBC) compared with historical controls with standard GC. Objective: To determine the safety and efficacy of neoadjuvant DDGC in MIBC. Design setting and participants: Patients with cT2-4a, N0-1, M0 MIBC were eligible and received three 14-d cycles of DDGC with pegfilgrastim support followed by radical cystectomy with lymph node dissection. The primary end point was the pT0 rate. Molecular subtypes were assigned and correlated with survival. Results and limitations: Thirty-one patients were evaluable for toxicity and response, of whom 58% had baseline clinical stage >T2N0M0; the median age was 69 yr. Ten patients (32%, 95% confidence interval [CI] 16-49%) achieved ypT0N0 status at cystectomy. Another four patients (13%, 95% CI 1-25%) were downstaged to non-muscle-invasive (
