Molecular detection of human papillomavirus type-16 DNA in cervical cancer tissue biopsies

ABSTRACT

The aim of the study is to detect the frequency of human papillomavirus type-16 among patients with cervical carcinoma. Khartoum Hospital, Army Medical Hospital and Soba University Hospital, Sudan. Descriptive-cross sectional study. Fifty specimens of treated cervical biopsy sections [Paraffin embedded] were included in the study from April to October 2012. DNA was extracted followed by the detection of E6 gene of human papillomavirus type-16 using non-probed SYBER green real-time PCR. Thirty [60%] showed positive results as compared with the sigmoid curve of the positive control for HPV type-16; while 20 [40%] were negative. Most of the positive results were among the age group 31-50 years. Human papillomavirus type-16 was detected in 60% of women with cervical cancer, which seems to have a strong association with cancer development.
