Digital Cervicography by Simply Portable Device as an Alternative Test for Cervical Cancer Screening in Rural Area of Thailand

Abstract

Objective: Various screening methods for cervical cancer are proved to be effective in reducing such type of cancer.<br />We aims to introduce a new portable device as an alternative method for cervical cancer screening. The performance<br />of device was tested on the assessment of cervical lesions using cervicograph score with the cervical cytology.<br />Methods: 325 non-pregnant women were tested from March 2013 to August 2015. The cervical and vaginal cells<br />from the sample were collected for cytology, then all of them received the digital cervicography conducted with our<br />new device and scored using cervicograph score. Small pieces of cervical tissues were also collected for histologic<br />examination. SPSS software version 18.0 was used for the statistical analysis. Results: We grouped cytology results<br />and cervicograph scores to 2 subgroups, ≤ ASC-US and ≥ LSIL, and 0-3 points and 4-6 points, respectively. The data<br />then correlated with histology results which sub-grouped to ≤ CIN 1 and ≥ CIN 2. The accuracy, sensitivity, specificity,<br />and positive predictive value (PPV) of cervicograph scores 4-6 points to detect CIN 2+ were 92%, 72.41%, 97%, and<br />84%, respectively which were not inferior to Pap smear did. Conclusion: The digital cervicography device provides<br />similar accuracy to Pap cytology screening and is suitable to use in the area that lacks cytoscreeners. Large scale use<br />and generalization are required for this new device.
