Challenges in integrating cervical cancer screening in HIV care clinics in West Africa: a pilot study in Abidjan, Côte d’Ivoire
Infectious Agents and Cancervolume 5, Article number: A10 (2010)
The ongoing scale-up of antiretroviral therapy (ART) in low-resource settings continues to improve the prognosis of HIV-infected individuals, necessitating a focus on long-term case management especially in women. Facing the particularly high burden of cervical cancer in sub-Saharan Africa, preventive measures are therefore becoming an integral component of a comprehensive approach to the management of patients. We describe here some of the operational aspects of a cervical cancer screening procedure based on visual inspection among HIV-positive women attending ART clinics in Abidjan.
A cross-sectional study is being conducted in two HIV clinics of Abidjan, since August 2009. A mobile team composed of three trained midwives and a senior gynecologist is in charge of proposing cervical screening based on visual inspection to all HIV-infected women attending participating clinics. Midwives are in charge to perform visual inspection of the cervix with acetic acid (IVA) and lugol’s iodine (IVL). Exclusion criteria are following: no previous cervical cancer or total hysterectomy, aged <25 or >59 years, pregnancy over 20 weeks. They refer positively screened women (IVA+ or IVL+), to a gynecologist in charge of the colposcopy examination (and biopsy if needed). Women with confirmed lesions are proposed an adapted treatment according to local available resources.
Of the first 1,653 HIV-positive women, who attended the cervical screening consultations, 49 were not eligible and 103 were not assessable because of a prevalent cervical infection. The median age of the 1,501 screened women was 37 (IQR 32-43) years, and 1171 (78%) were on ART. 133 (9%) women were positively screened for cervical pre malignancy and referred for medical examination. 69 (4.6%, 95% CI 3.5-5.6) were confirmed by colposocopy and had histological investigation. Results of the 69 biopsy performed were as follows; 48 cervical intraepithelial neoplasia (CIN) of grade 1, 8 CIN grade 2 or 3, 2 invasive carcinoma and 10 nonmalignant findings. 22 patients were treated with cryotherapy, 16 were referred for surgical excision, and 31 were proposed a gynecological followup.
Several barriers were identified as limiting the ability of visual inspection used as a cervical screening method such as a high rate of cervical infection or a high rate of false-positive cervical lesions. Health care systems in West African countries cannot afford the financial and structural burdens of a conventional cervical screening program. Strategies adapted to HIV-infected women and relying on visual inspection appear feasible despite stated limitations and should be further evaluated.
