Abstract
Objective:To investigate the value of detection of point mutations in the p53 gene in bile for diagnosis of gallbladder cancer(GBC).Methods:Genetic alteration of the p53 gene was examined in bile specimens of 15 GBC cases and 10 cases of benign gallbladder disease using PCR(polymerase chain reaction)-SSCP(single-strand conformation polymorphism) combined with silver staining. Cytologic diagnosis was performed with all of bile specimens.Results:Sensitivity and specificity of bile cytologic diagnosis for GBC were 13% and 100% respectively. The p53 gene mutation was detected in nine of the 15 GBC cases examined(60%), and not in all of 10 benign bile specimens. The DNA analysis demonstrated the presence of p53 gene mutations in 8 cases of GBC with false-negative cytologic diagnosis.Conclusion:Detection of point mutations in the p53 gene in bile is highly specific for diagnosing GBC and may be a valuable diagnostic modality for GBC.关键词
