ABSTRACT
Objective To evaluate the role of CD44v6 and matrix metalloproteinase-2(MMP-2) in the invasion and metastasis of gallbladder carcinoma (GC). Methods Immunohistochemical techniques were adopted to detect the expression of CD44v6 and MMP-2 in 42 cases of GC and 10 cases of cholecystolithiasis. Results (1)The expression of CD44v6 in the GC group (64.3%, 27/42) was significantly higher than that in the cholecystolithiasis group (0%,0/10). The expression of CD44v6 was correlated with GC histologic grade (P
ABSTRACT
Objective To evaluate the expression of CyclinD1 in gallbladder carcinoma and its relationship with clinlicopathological parameters.Method SABC immunohistochemistry was used to detect the expression of CyclinD1in 41carcinoma,15 chronic cholecystitis,10 normal tissue of gallbladder .Gallbladder carcinoma cell proliferation condition was detected by PCNA counting score .Results There were no positive signal of CyclinD1 deteted in chronic cholecystitis and in normal tissue,the positive rate of CyclinD1 in gallbladder carcinoma was 58.5%(24/41).The expression of CyclinD1 was related to tumor TNM stage, lymph node metastasis and cell differentiation (P
