Sarcomatoid lung carcinomas show high levels of programmed death ligand-1 (PD-L1) and strong immune-cell infiltration by TCD3 cells and macrophages
文摘

PD-L1, tumor-infiltrating lymphocytes (TIL) were higher in SC than in NSCLC.

High levels of TIL constituted a factor of good prognosis.

PD-L1 expression distinguishes subpopulations within tumor-infiltrating lymphocytes (CD3+ or CD4+) with different prognosis.

This result could represent a justification for the use of PD-L1/PD-1 immunotherapy.
