Programmed death ligand 1 expression in bladder rhabdomyosarcoma and its association with clinicopathological features.

ABSTRACT: The aim of this study was to detect PD-L1 expression in bladder rhabdomyosarcoma and its association with clinicopathological features and patient prognosis. PD-L1 expression was detected in paraffin-embedded sections obtained from 34 patients with bladder rhabdomyosarcoma via immunohistochemistry. Immunohistochemistry results were statistically analyzed to determine their association with patient clinicopathological features and survival outcomes. PD-L1-positive staining was observed in 47.1% (16/34) of patients. Metastatic tumor cells in the lymph nodes of two patients were positive for PD-L1 expression. PD-L1 expression was significantly different with regard to muscularis invasion, but the expression did not affect patient survival outcomes. We confirmed PD-L1 expression in bladder rha
