Abstract

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