Cervical Precancer Treatment Outcomes in Cameroon

The ablative and excision treatment procedures are effective, accessible, and affordable in resource-constrained settings, but the rollout and posttreatment follow-up are not remarkable. The outcomes of treatment procedures among women treated for precancerous lesions of the cervix have not been adequately studied in Cameroon. This study assessed the outcome of ablative and excisional treatment procedures.

This was a cross-sectional study that assessed the clinical outcome of 170 women treated for cervical precancers using ablative and excisional procedures in 2019 and 2020. Demographic and clinical data (treatment and posttreatment follow-up) were abstracted from the program registry. The data was analyzed to assess the clinical outcomes of cervical precancer treatment. The association between each independent variable and the dependent variable was examined in a simple logistic regression. All variables with p < 0.2 in the bivariate logistic regression model were subjected to a multivariable logistic model to get rid of cofounders and obtained adjustable odds ratios. The data was summarized using odds ratios, with p-value < 0.05 considered significant. All statistical analyses were performed using STATA version 17.

The cervical precancer treatment effectiveness of 93.55% was disaggregated into 94.37% and 88.23% for ablative and excisional procedures, respectively, with less severe adverse clinical effects. Despite the high awareness of women on the importance and timing of posttreatment follow-up, its uptake was 54.71%. Most of the women who got pregnant after the procedures delivered live and healthy babies. Women who were HIV positive were 89% (0.89 times) [aOR = 0.11, 95%CI (0.01 0.85), p = 0.034] less likely to have effective treatment for cervical precancer when compared to HIV-negative women. Those with low-grade lesions were eight times [aOR = 8.39, 95%CI (1.10 64.06), p = 0.04] more likely to have effective treatment for cervical precancer treatment compared to those with high-grade lesions.

Ablative and excisional treatment procedures for cervical precancer were effective with limited adverse effects in Cameroon. Women living with HIV and those with large lesions experienced lower treatment effectiveness. Most of the women who got pregnant after the procedures delivered live and healthy babies. Posttreatment follow-up which is highly recommended because of recurrent/persistent lesions was barely above average.
