The goal of this study is to establish a novel community-based breast cancer program to address delayed presentation and lack of access to diagnostic and treatment facilities in South-West Nigeria. It is aimed at evaluating the impact of a novel breast cancer early detection program using triple mobile assessment (innovative handheld iBreast Exam [iBE] device, mobile ultrasound, and mobile mammography) and patient navigation program in a Nigerian community.
This study aims to provide screening to asymptomatic women 40-70 years and to provide diagnostic evaluation to women 30-70 years presenting with breast symptoms in a community in South-West Nigeria.
The project will use a cluster randomized design with 1 community serving as the intervention arm and another community serving as the control arm. Both communities will receive breast cancer awareness and education but only the intervention community will receive screening, mobile imaging and navigation. Screening with targeted clinical history, Clinical Breast Exam (CBE), and iBE will be performed by trained Community Health Nurses in the intervention community. Women with positive CBE or iBE findings will undergo breast imaging with mobile mammography and portable ultrasound, as well as biopsy when indicated by the Radiologist who visits the community once a month, and receive navigation by the nurses to the point of care. The control population will receive breast cancer awareness without an organized screening, imaging or navigation program. Women presenting to the Primary Health Care Centers in the control community will be referred to the Teaching Hospital as per current standard of care. Record of all breast cancer cases seen in the 2 communities during the study period will be obtained.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Control | No Intervention | Two districts in Ife East Local County with an estimated screening population of 4,500 will be randomly selected to serve as the control community. The control arm will not receive iBE screening and clinical breast examinations by the community health nurses and nor get navigated to have ultrasound, mammography, biopsy and referral for treatment to the tertiary hospital if indicated within their community. All women for screening and diagnostic workup in the control community will be directed to the tertiary hospital to receive breast care. | |
| Intervention | Experimental | Three districts in Ife North Local County with an estimated screening population (women 40-70 years) of 5,800 will be randomly selected to serve as the intervention community. Women in the intervention community will receive iBreast and clinical breast examinations by the community health nurses and get navigated to have ultrasound, mammography, biopsy and referral for treatment to the tertiary hospital if indicated within their community. |

|---|---|---|---|---|
| iBreast device | Device | The iBreast (iBE) device is an automated, battery powered, portable device designed to be used by community health nurses as a screening and triage tool. The iBE is designed to be used by a community health worker or lay person after appropriate training. In resource-limited settings, it potentially provides an easily accessible, low-cost method to assess the breast for findings that warrant further evaluation. |
| Measure | Description | Time Frame |
|---|---|---|
| Participation rate | Percentage of women screened of the total number of eligible women in each community. | After year 1 of the 2-year study period |
| Abnormal call rate | Number of women with abnormalities detected on iBE and/or CBE requiring further evaluation either by imaging or biopsy out of the total number of women screened. | After year 1 of the 2-year study period |
| Breast cancer detection rate | Number of histologically diagnosed cases of breast cancer per 1,000 screened populations. | After year 1 of the 2-year study period |
| Stage at presentation | The tumour, node and metastasis (TNM) stage among those with histologically confirmed breast cancer. | After year 1 of the 2-year study period |
| Timeline from presentation to treatment | Time interval between presentation for screening in the community and treatment in the tertiary hospital | After year 1 of the 2-year study period |
| Retention rate | Number of women who return for repeat annual screening of the total initial number of women screened. | After year 2 of the 2-year study period |

The study will be carried out in 2 local counties (Local Government Areas) in Osun State, South-West, Nigeria, Ife North Local County and Ife East Local County. Three districts in Ife North Local County with an estimated screening population (women 40-70 years) of 5,800 will be randomly selected to serve as the intervention community, while 2 districts in Ife East Local County with an estimated screening population of 4,500 will be randomly selected to serve as the control community. Both communities will receive awareness and education, but only the intervention community will receive screening and navigation.

| Clinical Breast Examination | Other | The standard clinical breast examination (CBE) will be performed by the community health nurses in the selected primary health care centers where patients will present for screening or diagnostic workup in the intervention community |
|
|
| Breast ultrasound | Diagnostic Test | Women in the intervention community who have positive iBE and/or CBE findings will be navigated by the community health nurses to have ultrasound with or without ultrasound-guided breast biopsy if indicated by the radiologist using portable ultrasound tablets that will be brought to the intervention community. |
|
| Mammography | Diagnostic Test | Women in the intervention community who have positive iBE and/or CBE findings will be navigated by the community health nurses to have mammography done using a mobile mammography van that will be brought to the intervention community. |
