CP and neoplasm: Thus, in this study, we set out to address the following questions: (a) how are CP and IP gene expressions (dys)regulated in tumours; (b) what proportion of the cells are expressing CP and IP within the tumour; (c) what tumour cell‐intrinsic and cell‐extrinsic factors influence the expression of CP and IP; and (d) how does that affect the prognostic association and response to immune checkpoint blockade (ICB) therapies.
