Additionally, in some epithelial cancers such as non‐small cell lung cancer (NSCLC) and melanoma, as well as hematopoietic tumors like diffuse B‐cell lymphoma and Burkitt lymphoma, the absence of IL‐24 protein expression correlates with disease stage and is indicative of a poorer prognosis. This evidence concerns the gene IL24 and non-small cell lung carcinoma.
