The frequency of Human papilloma virus genotypes in cervical cancer tissues Miloš Glišanović Regional Centre for Talented Youth Belgrade II, Serbia, glisha@europe.com Introduction Cervical cancer is second most common cancer among women worldwide. Serbia has the highest incidence of cervical cancer in Europe.[1] According to their oncogenic potential, HPV genotypes are classified in two groups: high-risk and low-risk. HPV genotypes 16 and 18 belong in high-risk group and they appear in 6479% cases of cervical cancer.[?] Objective: The aim of this study was to determine the incidence of HPV genotypes in cervical cancer tissues of women in Serbia’s population. Picture No.1 – Gel electrophoresis for PCR products analysis Materials and methods: The study included 24 tissue samples from cervical cancer of women aged 36 to 75 years. The presence of HPV in the tissue samples was determined using PCR technique for the detection of HPV DNA with GP1 and GP2 primers for E1 gene. The procedure involved deparaffinisation of tissue sections, DNA extraction, PCR, gel electrophoresis for visualization of the PCR product and genotyping of HPV using direct DNA sequencing method.

Cervical Human papillomavirus infection in Serbia: risk factors, prevalence and genotype distribution in women with normal cervical cytology. Arch Biol Sci 2012; 64(4): 1277-1283. Results: Out of 24 analyzed cervical cancer tissues the presence of HPV DNA was demonstrated in 70,83% samples. Genotyping revealed the presence of 6 HPV types 16, 18, 33, 45, 53 and 58. The most frequent genotype was HPV 16 (70,5%). Conclusion: The results of this study and further research will provide more detailed informations about the distribution of HPV genotypes in cervical cancer tissues of women in our population. These informations can be very useful in cervical cancer prevention. [2] Molijn A, Kleter B, Quint W, Van Doorn LJ. Molecular diagnosis of human papillomavirus (HPV) infections.
