ABSTRACT:
Introduction: Now the molecular epidemiology is a new experience. It’s was noted that ninety percent of mouth cancers are squamous cell carcinomas and recorded 0.96% year of all cancers in Indonesia. Human papilloma virus (HPV) was implicated in pathogenesis of cancer. As a remark, that mutations of p53 and c-myc are found 50% in cancer. Objective: Aims of this research were to know the relationship between the mouth squamous cell carcinoma (MSCC) with HPV infection, the presence of p53, and c-myc genes mutation. Methods and Material: Tissue biopsy frozen sections from Benign Mouth Squamous Cell (BMSC) and MSCC patients were collected from Mouth and Dental Department of Muwardi District Hospital in Solo—Indonesia. To amplify L1-HPV gene for fixed the HPV etiology, amplified p53 and c-myc genes continued with SSCP analysis and followed with measurement using densitometer to see mutation existence. The collected data were analyzed with Chi Square Test. Results: None of the sample of patients with BMSC with positive HPV showed p53 gene mutation or c-myc gene. From eleven samples obtained from patients with MSCC who were positive HPV showed 18.2% had mutations in the p53 gene and 9.1% had mutations in c-myc gene. The chisquare test was shown to have significant differences between the MSCC with HPV infection and the presence of p53 and c-myc genes mutation. Conclusion: HPV is a risk ingredient for MSCC.
