Tumor Mutation Burden and Checkpoint Immunotherapy Markers in NUT Midline Carcinoma

NUT midline carcinoma (NMC) is a rare, aggressive poorly differentiated carcinoma genetically defined by NUTM1 gene rearrangement. The purpose of this study was to determine the tumor mutational burden (TMB) and the expression of immunohistochemical (IHC) markers in NMCs that are generally used to i
