PD-L1 Expression in TNBC: A Predictive Biomarker of Response to Neoadjuvant Chemotherapy?

Table 3

The achievement of pCR according to levels of both stromal TILs and PD-L1 expression on neoplastic cell membranes (low TILs/low PD-L1; high TILs/low PD-L1; low TILs/high PD-L1; high TILs/high PD-L1).

		PD-L1 on neoplastic cells
TILs		<25%		≥25%
	pt	pt	pCR	pt	pCR
Low	32	32	25%	0
High	22	18	39%	4	100%
