We found that the following pathways were highly activated in the MT group of the Local‐SCLC cohort: B cells, CD8+ effector T cells, myeloid dendritic cell activation, gamma delta (γδ) T cell activation, natural killer (NK) cell‐mediated immunity, and other pathways related to immune cell function (Figure 4a,b). Here, CD8A is linked to small cell lung carcinoma.
