Abstract
AIM: To explore the association of mucins (MUC1, MUC2 and MUC5AC) expression in serum with gastric cancer.
METHODS: Mucin protein chip was made using monoclonal and multiclonal antibodies and then applied to measure the levels of serum MUC1, MUC2 and MUC5AC in 30 gastric cancer patients and 30 healthy adults using the method of immunofluorescence (carcinoembryonic antigen as an indicator).
RESULTS: The levels of serum mucins and CEA in gastric cancer patients were significantly higher than those in the healthy controls. The positive expression of MUC1 was related with the TNM staging for gastric cancer (P = 0.0047), but the positive rates of MUC2 and MUC5AC expression had no relationship with the TNM staging (P = 0.136, P = 0.201). The positive rates of mucins expression were increased with the descending of cancer differentiation degree. Single mucin or either two mucins were sensitive and specific in the diagnosis of gastric cancer. For single mucin detection, MUC1 was the most sensitive and specific, with a sensibility of 81.5% and a specificity of 75.8%, respectively. Mucins in combination (at least 2 positive) had a sensibility of 96.0% and a specificity of 82.9%, respectively.
CONCLUSION: Serum mucins detection has higher sensibility and specificity in the diagnosis of gastric cancer, which may provide a new approach to early diagnose and prognose gastric cancer.
