Efficiency of HPV DNA Test versus Pap Smear in the Screening of Cervical Cancer

Abstract

Introduction: Cancer cervix is a common genital cancer. Human papillomavirus is the main cause of cervical cancer because of the strong association of certain HPV genotypes and the development of cervical cancer and its precursor lesions, cervical intraepithelial neoplasia CIN 2 or CIN3.
 Methods: The study was conducted on 180 gynecological patients seen at the outpatient department of Manipal Hospital, Bangalore. A comparative study of HPV DNA test with Pap smear in the screening of cervical neoplasia was carried out over the period of 24 months from August 2011 to June 2013.
 Results: The incidence of cervical cancer and its associated mortality has declined in recent years, largely due to the widespread implementation of screening programs by Pap smear testing. The management and the prevention of cervical cancer should change with HPV DNA testing for high risk HPV, which is more sensitive than pap smear testing. Infection of cervix with HPV is necessary to cause cervical neoplasia and cervical cancer. Persistent infection with HPV is required for the development of cervical dysplasia and invasive cervical cancer.
 Conclusions: HPV testing alone for primary screening appears promising in women aged 30 years and older as this group is at greatest risk of developing CIN 3. As compared with Pap testing, HPV testing has greater sensitivity for detection of cervical intraepithelial neoplasia.

Correlation of Sonographic Morphologic Index and CA-125 in Predicting the Nature of Ovarian Tumor

“…In the present study sensitivity, specificity, PPV, NPV and accuracy of MI score for predicting malignancy in ovarian tumors was 1.00, 0.818, 0.529, 1.00 and 0.849 respectively. Similar results were observed by Sassoneet al 13,14…”

Does Liquid-Based Technology Improve Detection of Cervical Epithelial Abnormalities and Worth in Low Resource Setting?

“…HPV testing and Pap smear did not differ significantly for detecting LSIL in their study. Though HPV testing alone proved to be promising for primary cervical screening in the study conducted in India by Pradhan et al, the study was conducted in a small sample size [25]. The cost effectiveness is the limitation for implementation of HPV testing in cervical cancer screening in the countries like India and Nepal with low resource setting.…”

“…[4,23] Many included multiple technologies in their studies (such as ThinPrep Pap test, SurePath Pap test, and/or other technologies not approved by the FDA) [5,17]. [25]. In contrary, an 11-year retrospective study conducted in Korea by Kang et al demonstrated that Pap smear had greater sensitivity and specificity for detecting HSIL and SCC when compared to HPV testing [26].…”

The Relationship between Perceived Self-Efficacy and Cervical Cancer Screening among Village Health Volunteers in Suratthani Province, Thailand

“…If a cell abnormality is detected, the technician can test the remaining specimens for HPV using HPV DNA testing without collecting new epithelial cells. After that, treatment planning can be continuously carried out (Pradhan et al, 2018).…”
