Abstract:
Objective To evaluate the changes and clinical significance of the serum level of homocysteine (Hcy) in esophageal cancer patients before and after surgery.Methods The serum Hcy concentrations of 168 patients with esophageal cancer and 50 healthy individuals were measured by enzymatic cycling.Results Total Hcy levels were significantly raised in patients group when compared with the levels in control group [(19.6±6.1) μmol/L vs (13.0±2.3) μmol/L,P =0.001].Hcy levels were significantly lower in postoperativepatients groups compared with preoperativegroup [(17.0±8.5),(15.8±6.4),(12.8±5.6) μmol/L vs (20.6±9.1) μmol/L,all P ＜ 0.05].Also,Hcy levels in patients with esophageal cancer were significantly higher than in the tumor length＞ 5cm group and the ＜3 cm,3-5 cm group [(23.6±9.6) μmol/L vs (18.1±6.3),(19.6±6.6) μmol/L,P =0.036,P =0.021].Compared with other T stage groups,significantly higher level of Hcy was found in T4 stage group [(29.5±1.7) μmol/L vs (18.5±6.9),(18.8±8.0),(20.6±8.8) μmol/L,all P ＜ 0.001].There was no significant difference between the mean Hcy concentrations of the node-positive and nodenegative group [(20.2±9.3) μmol/L vs (20.3±7.6) μmol/L,P =0.897].Compared with negative lymphaugial tumor-cells thrombus group,positive group had low Hcy level [(16.7±3.4) μmol/L vs (21.1±8.9) μmol/L,P =0.007].Conclusion These results showed that serum Hcy levels play important roles in the development of esophageal cancer.
