A group from Department of Laboratory Medicine, Shanghai Tongji Hospital, School of Medicine, Tongji University, Shanghai, China,etc. has reported about a serum biomarker for non-small cell lung cancer (NSCLC) .
Plasma versican and plasma exosomal versican expression in NSCLC patients was significantly upregulated and was significantly higher in T3 + T4 patients compared with T1 + T2 patients (P < 0.05) as shown below (ROC curve). Versican is a large chondroitin sulfate proteoglycan. The plasma versican and plasma exosomal versican were detected using an ELISA kit (made in China).
