ABSTRACT
The clinical application of digestive endoscopic technique in the field of pancreaticobiliary diseases profoundly affects or even overturns many traditional thoughts. From endoscopic sphincterotomy and endoscopic biliary drainage to endoscopic ultrasonography-guided drainage and debridement of infectious pancreatic necrosis, and pancreatic pseudocyst drainage at present, digestive endoscopic technique helps to achieve revolutionary changes in disease diagnosis and treatment, especially during the past two or three years. In order to help clinicians in the field of pancreaticobiliary diseases quickly understand the latest research advances in digestive endoscopy and related advanced techniques, this article elaborates on the latest research advances in digestive endoscopy in the field of pancreaticobiliary diseases.
ABSTRACT
Objective To explore the expression and clinical relevance of metastasis-associated colon cancer-1 (MACC1) and C-MET proteins in hepatocellular carcinoma (HCC) tissue.Methods The expressions of MACC1 and C-MET were detected in 51 specimens of HCC and paraneoplastic liver tissue,normal liver tissue in 13 healthy cases using immunohistochemistry and Western blotting.The correlations of the expressions of MACC1 and C-MET proteins were evaluated,survival rates were observed,the relationship between the expression of MACC1,C-MET proteins and the clinicopathologic features of HCC were analyzed.Results The positive rate of MACC1 and C-MET proteins was 80.4％ and 76.5％ in HCC tissue,the relative expressions were 0.645 ± 0.047 and 0.504 ± 0.023 respectively,which was significantly different from those in paraneoplastic liver tissue and normal liver tissue (respectively F =173.308,252.817,all P =0.000).The survival analysis showed that the three-year survival rate in patients with positive MACC1 and C-MET expressions was significantly lower than that in patients with negative expressions (respectively x2 =3.934,4.439,all P ＜ 0.05),the positive rate and relative expressions of MACC1 and C-MET were significantly correlated with TNM stage,portal vein cancer thrombus and pathology typing (P ＜ 0.05).Conclusions The expression of MACC1 and C-MET is associated with the malignant progression of HCC.MACC1 may serve as a independent prognostic factor for advanced HCC and a possible therapy target for the treatment of HCC.
