Prevalence of cervical abnormalities among rural women in KwaZulu-Natal, South Africa

Abstract

Introduction: despite the availability of screening facilities in South Africa, cervical cancer prevalence and mortality is still high. Most women present to the health facilities at an advanced stage of disease. This study aimed to determine the prevalence of cervical abnormalities using the revised Bethesda System among rural women in KwaZulu-Natal, South Africa.

Methods: this was a cross-sectional descriptive study using a retrospective medical record review method to collect data on Pap smears from three rural clinics in KwaZulu-Natal. Clinical data and cytology reports were obtained for the years January 2016 to January 2019. Women aged 18-65 years were included.

Results: of 246 randomly-selected medical records, 245 Pap smears were analysed. Half (47.8%) of the women were in the age group 30-44 years. HIV, as a risk factor, was found in 41.2% of the women. A total of 48.6% Pap smears were negative for malignancy. Of the 49.8% abnormal screened results, 25.7% women had low-grade squamous intraepithelial lesion, 13.9% high-grade squamous intraepithelial lesion (HSIL), 8.6% atypical squamous cells of undetermined significance, and 1.6% squamous cell carcinoma (SCC). All SCC cases were found in HIV-infected patients. HSIL and SCC were less common among patients younger than 30 years.

Conclusion: this study´s results accentuate the importance of well-organised cervical screening programmes. Cervical screening, through Pap smears, is a useful, non-invasive and cost-effective method for early detection of pre-invasive lesions. Women, especially those over 30 years, should be educated on the importance of Pap smears and encouraged to uptake the test.
