The study published in The American Journal of Pathology found that high levels of cytoskeleton-associated protein 4 (CKAP4) have been identified in the blood of patients with lung cancer than in healthy individuals. The results of our study provide evidence that the CKAP4 protein may be a novel early sero-diagnostic marker for lung cancer said co-author Ryo Nagashio from Kitasato University School of Allied Health Sciences in Japan. The disease is associated with a poor prognosis because most lung cancers are only diagnosed at an advanced stage. Current biomarkers for lung cancer includes carcinoma embryonic antigen (CEA) sialyl Lewis X
