Abstract:Objective To investigate the value of MIC-1 and G17, PG1 in the diagnosis of gastric cancer and the expression variation after pathogen infection. Methods From April 2010 to August 2015, 120 cases of early gastric cancer and 140 cases of gastric cancer in the hospital were analyzed. The serum MIC-1 and G17, PG1 concentration were assayed by ELISA method. The serum MIC-1 and G17, PG1 were detected in infected patients after operation. At the same period, 120 healthy subjects and 110 un-infected patients in our department were taken as control. Results The serum MIC-1 and G17, PG1 were increased greatly (P < 0.05) in gastric cancer patients compared with control. These parameters were also up-regulated (P < 0.05) after infection. The result also showed that serum interleukins, including IL-1, IL-2, IL-3, IL-6 and IL-10 had similar changes with MIC-1. Conclusions MIC-1 and G17, PG1 are potential indicators in the diagnosis of gastric cancer and can be increased after infection.
