Oncogene-driven type: In oncogene-driven immune microenvironments, tumor cells are endowed with rapid proliferation, resistance to apoptosis, increased expression of inhibitory checkpoints, and the induction of angiogenesis in the presence of driver genes; this is more common in oncogene-driven tumor tissues such as epidermal growth factor receptor (EGFR)-driven tumors, MYC-driven tumors, and Kirsten rat sarcoma (KRAS)-driven tumors [30–32]. Here, KRAS is linked to neoplasm.
