CXCL8 and lung carcinoma: The analysis showed that IL-8 deregulation has different implications in different cancer types, for instance, in case of gastric cancer patients the high expression of IL8 gene is found to be associated with less number of patients at risk (more survival rate); whereas, in case of lung cancer patients the high expression of IL8 gene is found to be associated with more patients at risk (less survival rate) (Fig. 8).
