2025 Background: In low-income countries where mammography is not widely available, optimal strategies to facilitate earlier breast cancer detection are not known. We previously conducted a cluster randomized clinical trial of clinician trainings in Burera District in rural Rwanda to facilitate earlier diagnosis among symptomatic women; 1.3% of women evaluated at intervention health centers (HCs) were diagnosed with cancer. Early stage breast cancer incidence was higher in intervention areas. Subsequently, Rwanda Biomedical Centre, Rwanda’s national health implementation agency, adapted the program in 3 other districts, offering screening clinical breast exams (CBE) to all women aged 30-50 years receiving cervical cancer screening and any other woman requesting CBE. A navigator facilitated patient tracking. We sought to examine patient volume, service provision and cancer detection rate in the adapted program. Methods: We abstracted data from weekly HC reports, facility registries, and the referral hospital’s electronic medical record to determine numbers of patients seen, referrals made, biopsies, and cancer diagnoses from July 2018-December 2019. Results: CBE was performed at 17,239 visits in Rwamagana, Rubavu and Kirehe Districts (total population 1.34 million) over 18, 17 and 7 months of program implementation respectively. At 722 visits (4.2%), CBE was abnormal. 571 patients were referred to district hospitals (DH); their average age was 35 years. Of those referred, 388 (68.0%) were seen at DH; 32% were not. Of those seen, 142 (36.6%) were referred to a referral facility; 121 of those referred (85.2%) actually went to the referral facility. Eighty-eight were recommended to have biopsies, 83 (94.3%) had biopsies, and 29 (34.9% of those biopsied; 0.17% of HC visits) were diagnosed with breast cancer. Conclusions: Integrating CBE screening into organized cervical cancer screening in rural Rwandan HCs led to a large number of patients receiving CBE. As expected, patients were young and the cancer detection rate was much lower than in a trial focused on symptomatic women. Even with navigation efforts, loss-to-follow-up was high. Analyses of stage, outcomes, patient and provider experience and cost are planned to characterize CBE screening’s benefits and harms in Rwanda. However, these findings suggest building health system capacity to facilitate referrals and retain patients in care are needed prior to further screening scaleup. In the interim, early diagnosis programs targeting symptomatic women may be more efficient and feasible.
