Using the median nearest neighbor distance from malignant cells to various primary TAICs, we observed that in NSCLC, the median distance from malignant cells to CD3 + T-cells was 36.46 μm; to CD20 + B-cells, 104.61 μm; to CD68 + macrophages, 42.24 μm; and to CD66b + PMNs, 87.24 μm (Table 2). The gene discussed is CEACAM8; the disease is non-small cell lung carcinoma.
