title = "Genomic Differences Between “Primary” and “Secondary” Muscle-invasive Bladder Cancer as a Basis for Disparate Outcomes to Cisplatin-based Neoadjuvant Chemotherapy [Figure presented]",
abstract = "Patients with secondary muscle-invasive bladder cancer (MIBC) treated with neoadjuvant chemotherapy had worse clinical outcomes than patients treated similarly with primary MIBC. These contrasting clinical outcomes may have resulted from differing rates of cisplatin-sensitizing ERCC2 mutations that were enriched in primary MIBC.",

note = "Funding Information: Our results suggest that primary and secondary MIBC have disparate clinical outcomes and differential responses to cisplatin-based NAC. Genomic analysis of chemotherapy-na{\"i}ve specimens reveals that primary MIBC, but not secondary MIBC, is more likely to harbor likely pathogenic ERCC2 mutations predicted to be sensitizing to cisplatin-based chemotherapy. Although cystectomy should ideally be performed before NMIBC progresses to secondary MIBC, the findings of our study suggest that patients with secondary MIBC derive little benefit from current standard cisplatin-based NAC. Further investigation is warranted into whether upfront cystectomy or enrollment into clinical trials of novel agents may be a preferred clinical approach for secondary MIBC.
