Association of immunohistochemical markers of tumor subtype with response to neoadjuvant chemotherapy and survival in patients with muscle-invasive bladder cancer.

Purpose: A readily accessible biomarker to identify which patients with bladder cancer are more likely to respond to neoadjuvant chemotherapy (NAC) could help clinicians avoid unnecessary chemotherapy and prevent its subsequent complications in some patients. The primary objective of this study was to investigate the association of immunohistochemical markers of tumor subtype with response to NAC and survival of patients with muscle-invasive bladder cancer (MIBC).

Materials And Methods: MIBC patients treated with NAC were retrospectively included.
