Abstract
AIM: To detect the expression of P53 and K-ras in gallbladder benign lesions and malignant diseases, and to examine their clinical significance.
METHODS: Twenty specimens with cholesterol polyps, 22 with adenoma of gallbladder, 25 with primary gallbladder cancer (PGC) (including 5 with atypical hyperplasia and carcinoma in situ) were examined in this study for P53 and K-ras' expressions using immunohistochemistry. A statistical analysis was performed.
RESULTS: Aberrant expression of P53 and K-ras was present in benign lesions. The positive rate was significantly higher in patients with adenoma of gallbladder than with cholesterol polyps (72.7% vs 35.0%, P = 0.014; 90% vs 75.0%, P = 0.167). Expression of P53 and K-ras was the lowest in patients with cholesterol polyps. Paired comparison between P53 and K-ras showed no significant difference, which indicated a possible synergistic interaction in development of gallbladder cancer.
CONCLUSION: Expression of P53 and K-ras shows significant difference and its positive rates are on the increase among cholesterol polyps, adenoma of gallbladder and primary gallbladder cancer (PGC).
