Abstract Neoadjuvant cisplatin-based chemotherapy (NAC; 70 mg/m2) is standard of care for muscle-invasive bladder carcinoma (MIBC). Many patients (pts) cannot receive cisplatin because of renal impairment, and administration of cisplatin 35 mg/m2 on day 1 + 8 or 1 + 2 (i.e., split schedule) is a commonly used alternative. In this retrospective analysis, we compared complete (pT0) and partial (<pT2) pathologic response rates between split schedule (SS) and conventional schedule (CS) pts, after 1:1 matching on chemotherapy regimen, number of cycles, tumor histology, and clinical stage. Eighty matched pts were identified. pT0 rates were 17.5% (95% confidence interval [CI], 7%–33%) and 32.5% (95% CI, 19%–49%) in SS and CS cisplatin pts, respectively (p = .21), corresponding to an odds ratio for pT0 of 0.45 (95% CI, 0.16–1.31) with SS cisplatin. Split schedule cisplatin was associated with numerically but not statistically significant lower pathologic response rates relative to full dose.
