BACKGROUND: Cervical cancer is a preventable cancer. There has been a marked reduction
of cervical cancer related mortality in high income countries, due to organised screening services
using Pap smear cytology as a screening tool. In low income countries due to challenges in
implementation of screening with Pap smear, there is a high morbidity and mortality rate from
cervical cancer. To address this scourge, alternative screening methods such as Visual Inspection
with Lugol’s Iodine (VILI) and Visual Inspection with Acetic acid (VIA) have been considered,
however their validity must be continually assessed in different populations.
OBJECTIVE: To compare diagnostic performance of VILI, VIA, and Pap smear cytology as
screening tests for cervical cancer.
METHODS: It was a comparative study, conducted in Amukpe, Sapele Local Government
Area, of Delta State, Nigeria. Ethical approval was obtained from the Health Research Ethics
Committee of DELSUTH. Participants were premenopausal women above 25years, who
consented after counselling to participate in the study. Participants underwent the index and gold
standard tests following this order: 1) speculum examination, 2) Pap smear sample collection, 3)
Colposcopy assessment (at low magnification), 4) consecutive VIA with Colposcopy (at high
magnification), 5) consecutive VILI with Colposcopy , 6) biopsy collection where indicated.The
data collected were inputted into SPSS version 22 and analysed.
