ABSTRACT
Objective To analyze the alterations of serum protein in ESCC,compare alterations of serum protein with and without LM. Methods Serum samples were collected from 64 ESCC patients before operation and 60 cases with gender and age-matched healthy controls,special serum protein or peptide spectra was determined by SELDI-TOF-MS measurement after treating the sample onto weak cation exchange (WCX2) protein chip for each case. The serum protein profiles were compared by Biomarker Wizard Software between the ESCC patients and healthy controls, and among ESCC patients stratified according to gender, age, location of tumor, size of tumor, infiltration and with or without LM. Results (1)120 protein peaks were detected at the molecular range of 0 to 50000 in comparing of ESCC patients and healthy controls. 31 significantly different peaks were found between ESCC patients and healthy controls (P <0.05), 10 peaks were selected(P<0.01). (2) One significantly different protein peak (m/z 4174) was detected between T1 and T3, T4 (P<0.05). (3) There were three significantly different protein peaks (m/z 3970,4174 and 4277) between with LM and without LM (P<0.05).The peak (m/z 4174) was shared by two groups above. (4) No significant different protein was found when patients stratified according to gender, age, location of tumor and size of tumor. Conclusion Significant difference exists in serum proteins between ESCC patients and healthy controls. There are statistical difference exists in serum proteins between T1 and T3, T4, with LM and without LM. This difference is less than between ESCC patients and healthy controls. Some commonness is existed in serum protein fingerprint for patients with serious infiltration and with LM.
