بررسی وفور عفونت ویروس پاپیلومای انسانی HPV در ضایعات بدخیم دهانه رحم به روش PCR مولتی پلکس

Background: Cervical cancer is the second leading cause of cancer death among women. In this cancer, the effects of prevention, early diagnosis and treatment more than other cancers decrease the mortality rate. In 1970 human papilloma virus (HPV) was introduction as major etiologic factor of cervical cancer. Different studies throughout the world revealed strong correlation between HPV and cancerous & precancerous changes in epithelial cells. Since cell culture and serological methods can not recognize the virus and its subtypes, the importance of the molecular methods including polymerase chain reaction (PCR) in early and definite diagnosis of virus is obvious. Methods: In this study, after patient selection using the related protocol and completion of the questionnaires, 100 samples from cancer lesions of cervix selected. Then DNA extraction from paraffin blocks performed using standard method. Multiplex PCR with two pairs of primer (one as internal control) performed and the PCR product run on 8% polyacrylamid gel. Results: The results showed that 73% of the tissues were infected by HPV. Conclusion: This finding confirm the previous results based of correlation between HPV,and cervical cancer.
