LCMC3 included an exploratory analysis that evaluated the peripheral blood gene expression of NK cells compared to RNA sequencing of the tumor microenvironment NK cells to predict MPR, finding that coexpressions of immunoglobulin-like \transcript 2 (ILT-2) and PD-L1 were associated with MPR in nonsquamous histology [40]. The gene discussed is LILRB1; the disease is neoplasm.
