Genotype Distribution of Human Papillomavirus in Women with Cervical Cancer and Normal Cytology in Malwa Region of Punjab- A Pilot Study
Journal Title: Journal of Clinical and Diagnostic Research - Year 2018, Vol 12, Issue 12
Abstract
ABSTRACT Introduction: Human Papillomavirus (HPV), a small circular double stranded DNA virus is the major aetiological agent of cervical precancerous and cancerous lesions. Genital HPV types are divided into high and low risk types, according to their oncogenic potential. The proportion of women infected with HPV varies greatly across populations as is the distribution of HPV genotypes. Aim: The present pilot study was conducted to determine the most frequent genotypes of HPV associated with: a) Histologically proven cases of cervical carcinoma; b) Women with normal cervical cytology. Materials and Methods: The present hospital based crosssectional study was conducted on 132 women attending Obstetrics and Gynaecology department of a tertiary care hospital. Consecutive cervical brushings were collected from women presenting with any type of cervical lesion and were subjected to cytology, histopathological examination, HPV DNA testing and genotyping by using Sacace real time PCR. Results: Of the 132 women studied between January 2014- October 2014, 50 (37.87%) had histologically proven cervical carcinoma and 82 (62.12%) had normal cytology. In proven cases of cervical carcinoma, HPV infection was found to be associated in 49/50 (98%) and all of them had high risk HPV genotypes. The most common genotypes were 16 (67.34%) and 18 (20.4%). Other genotypes present were 45 and 33. Out of 82 cytological normal women, five showed presence of HPV DNA on RT PCR. While all the five had infection of HPV genotype 18, in one there was presence of both 16 and 18 genotypes. Conclusion: The detection of HPV genotypes 16, 18 along with high risk type 33 and 45 in Malwa region of Punjab confirm the importance of identifying the types of HPV that infects this community to design more effective prevention strategies and thus contribute to fight against cervical cancer.
