Interestingly, in non-small-cell lung carcinoma (NSCLC) intratumoral neutrophils fail to show any association with overall survival [30], whereas the CD66b+ neutrophil to CD8 lymphocytes ratio is predictive of worse outcome [31], suggesting that the interaction of neutrophils and T cells might be important for the overall prognosis. Here, CEACAM8 is linked to non-small cell lung carcinoma.
