Cervical screening with Luviva machine for early detection of cervical dysplasia: experience from Ekiti state, Nigeria
Abstract
Background: Cervical cancer is a preventable and potentially curable cancer when detected early, yet it continues to be among the leading causes of cancer death in developing countries. Screening for cervical dysplasia is critical for early detection in order to reverse this trend. Several traditional screening methods such as pap smear test, HPV-DNA screening test, visual inspection with acetic acid or lugol iodine are in vogue with different specificity and sensitivity. LuViva advanced cervical scan is a new automated screening tool that has great promise for the detection of the disease in its
earliest form both in developing and developed countries.
Objective: This study was designed to describe our experience with the use of LuViva advanced cervical scan as a primary screening tool for cervical dysplasia.
Method: This is a descriptive cross-sectional study, whose data was obtained from the free health screening for civil servants in Ekiti State conducted between 11th and 21st February, 2014. Screening for Cervical dysplasia was conducted using the LuViva advanced cervical scan for women 40 years old and above. The result was automatically recorded and transferred to an Excel sheet for analysis.
Result: A total sum of 254 patients was screened during the study period. Only one patient had a prior pap smear done. The automated self-reporting LuViva scan presented the result of the benign changes on the cervix as low risk in 143 patients (56.3%), moderate risk in 52 patients 15%) and high risk in 59 patients (11.5%). The machine further classified the dysplastic changes of the low, moderate and high risk categories as Atypical glandular cell (AGC), Atypical glandular cell favouring neoplasia (AGC-FN), Atypical g l a n d u l a r c e l l o f u n d e t e r m i n e d significance(AG-US), Atypical squamous cell of undetermined significance (ASC-US), Atypical squamous cell where high grade cannot be excluded (ASC-H) and Low grade squamous Intraepithelial lesion (LSIL). The proportion of moderate and high risk AGC (31.2%) was just slightly lower than the moderate and high risk of ASC-US (35.2%) while a higher percentage of43.9% in low grade squamous intraepithelial lesion was recorded among the patients.
Conclusion: Our experience suggests that there is a place for the use of luViva scan in the primary screening for cervical dysplasia and there is a correlation between LuViva scan high risk result and histological diagnosis of cervical dysplasia.
