Another report on 61 locally advanced TNBC samples after neoadjuvant chemotherapy [23] determined 62.3%, 50.9%, and 26.2% of samples as positive for PD-1 (membranous staining > 1% on TILs), PD-L1 (membranous staining > 1% on either tumor or TILs), and LAG-3 (membranous staining > 1% on TILs), respectively. This evidence concerns the gene LAG3 and neoplasm.
