Immunohistochemical assessment of the diagnostic utility of <scp>PD</scp>‐L1: a preliminary analysis of anti‐<scp>PD</scp>‐L1 antibody (<scp>SP</scp>142) for lymphoproliferative diseases with tumour and non‐malignant Hodgkin–Reed‐Sternberg (<scp>HRS</scp>)‐like cells

Abstract

Immunohistochemical evaluation of PD-L1 expression in tumour and non-malignant HRS-like large cells may be useful for assessing either immune escape or immunodeficiency in their pathogenesis.
