Some chemokines were increased in LSCC samples, such as CCL2, CCL15, CCL16, and these chemokines were implicated in the angiogenesis or angiostasis balance and promoted tumor infiltrating hematopoietic cells in the pathophysiology of NSCLC (Rivas-Fuentes et al., 2015). This evidence concerns the gene CCL15 and non-small cell lung carcinoma.
