Abstract:
Objective To detect methylation of p16 gene in lung cancer tissues of non-small cell lung cancer patients,and to approach its clinical diagnostic value.Methods The methylation of p16 gene in DNA from 47 non-small cell lung cancer tissues and corresponding nomalignant tissues were tested with methylation-specific PCR(MSP).Results The total frequency of p16 methylation was significantly higher in lung cancer tissues than that in the corresponding malignant tissue(44.7%vs 17%)(P＜0.01).But there was no significant difference in detectiveness,clinical staging,clinical pathology type and clinical classification(P＞0.05).Conclusion The detection of methylation of p16 gene may be helpful to clinical diagnosis for non-small cell lung cancer,but its specify,sensitivity and feasibility need to be further studied.
