ABSTRACT:
Cervical cancer is caused by persistent infection with high-risk human papillomavirus (hrHPV) types. This study aimed to perform the community-based cervical cancer screening using Cobas HPV test and liquid-based-cytology (LBC) in married women by a cross-sectional descriptive method. A total of 312 married women were screened using LBC in 2017. Among them, 220 women aged between 30-49 years were also investigated using Cobas HPV test. Cervical cells were obtained from the cervix by sterile disposable cytobrush and collected in Cobas PCR-cell-collection-media. HPV DNA testing was performed by Cobas HPV Test. It is an automated, polymerase-chain-reaction and nucleic-acid-hybridization test for the detection of 14 hrHPV types in a single analysis. It identifies HPV-16 and HPV-18 specifically which are associated for over 70% of cervical cancer while concurrently detecting other 12 hrHPV types (-31,-33,-35,-39,-45,-51,-52, -56,-58,-59,-66-and-68) as pooled-12-hrHPV. In this study, hrHPV was identified in 5.5% (12/220) of women in general population of Kyauk Ye Twin Ward. Among HPV positive cases, pooled-12-hrHPV types were 66.7%, HPV-16 (25%) and HPV-18 (8.3%). Using LBC (Bethesda-system), negative-for-intraepithelial-lesion-or-malignancy (NILM) was 79.5% (248/312). Epi-thelial cell abnormalities such as atypical-squamous-cells and/or atypical-glandular-cells (ASC/AGC), low-grade-squamous-intraepithelial-lesion (LSIL) and high-grade-squamous-intraepithelial-lesion (HSIL) were detected 11.9% (37/312), 7.4% (23/312) and 1.3% (4/312), respectively.
