Abstract
AIM: To determine the expression of βig-h3 in peritoneal mesothelial cells in gastric cancer and to explore its relation to pathological parameters and peritoneal metastasis.
METHODS: Peritoneal tissue and peritoneal washing fluid samples were collected during operation from 75 patients with gastric cancer and 14 patients with benign gastric lesions. The expression of βig-h3 in peritoneal mesothelial cells was measured immunohistochemically. The mRNA levels of CEA in ascites and peritoneal washing fluid were measured by RT-PCR. Peritoneal lavage cytological (PLC) examination and pathological examination were also performed.
RESULTS: βig-h3 was positively expressed in the peritoneal tissue in 29 patients with gastric cancer and 1 with benign gastric lesions, and the positive rate was significantly different between the two groups (P = 0.030). In the gastric cancer group, 13 patients had evident peritoneal metastasis, 20 were positive for PLC, and 32 were positive for CEA mRNA. The positive rate of βig-h3 expression was significantly positively correlated with deep invasion (P = 0.016), serious serous type (P = 0.037), peritoneal metastasis (P = 0.002), PLC (+) (P = 0.005), and CEA mRNA (+) (P = 0.027).
CONCLUSION: βig-h3 expression in peritoneal mesothelial cells in gastric cancer patients is closely related with peritoneal metastasis, representing a marker of biological behavior of gastric cancer.
