Early experience scaling up a breast cancer early detection initiative integrated with cervical cancer screening in Rwanda

Background: Late-stage breast cancer contributes to a growing number of deaths in sub-Saharan Africa (SSA) but few studies examine scalable early detection strategies. Following small-scale pilots, in 2020 Rwanda launched an adapted Women’s Cancer Early Detection Programme (WCEDP), integrating clinical breast exam (CBE) for symptomatic patients with cervical cancer screening. A WCEDP-specific electronic health record (EHR) was developed to facilitate patient tracking.

Methods: We used the RE-AIM implementation science framework to retrospectively evaluate implementation of breast cancer early detection within the WCEDP over 12 months in the first three scale-up districts (population: 2 009 888), using routinely-collected electronic and paper data from 15 health centres and 3 hospitals. We examined the WCEDP’s Reach in the target population, Effectiveness linking patients to care, Adoption by facilities and fidelity to the Implementation protocol.

Results: Regarding Reach, average weekly health centre visits for CBE increased from 18 to 33 post-WCEDP launch; of 1688 women receiving CBE through the WCEDP, 12.0% were ≥50 years. Regarding effectiveness, among 383 women referred to district or referral hospitals, 157 (40.9%) had no documented referral facility visit. Of those seen at a referral facility, median days from health centre to district hospital visit and from district to referral hospital visit were 6 (IQR 1.8-14.8) and 8 (IQR 5.0-40.5) respectively. Among the 36 patients receiving biopsy, 72.2% were biopsied within 60 days of initial presentation. In terms of adoption, 79 clinicians were trained in cancer early detection, with 69.6% remaining at WCEDP facilities after 3 years. Regarding implementation fidelity, WCEDP clinics were held 52.6% of weeks. EHR data quality was inconsistent, with half of patients seen at district hospitals for breast care lacking EHR documentation.

Interpretation: Breast cancer early detection services can be implemented in resource-constrained SSA health facilities. Integration with cervical cancer screening may be a promising strategy. However, investing in data systems is critical to support programme evaluation and high-quality care.
