Exp Cell Res 2005, 307:427?35.Conclusions In conclusion, our study strongly suggests the prospective use of serum CEACAM1 along with the tissue S/L ratio of CEACAM1 as indicators for NSCLC diagnosis. Our study indicated that CEACAM1 could originate from tumour cells. In addition, the CEACAM1 isoform expression patterns could change even devoid of changing the quantity of CEACAM1 throughout oncogenesis.Zhou et al.
