Tablet-based Mobile Health Ultrasound for Point-of-care Breast Cancer Diagnosis in Nigeria

The purpose of this study is to train Nigerian radiologists to perform ultrasound-guided breast biopsies on women that present to the hospital with a suspicious breast mass. Before performing biopsies on patients, the Nigerian radiologists will have already successfully completed a competency-based mobile health ultrasound-guided breast biopsy-training program. This program, developed by experts in Nigeria and the United States of America, certifies that they have the skills required to safely perform these biopsies on patients.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Trained radiologists; Trainers will successfully train Nigerian radiologists	Other: Ultrasound-guided breast biopsy training program; This program, developed by experts in Nigeria and the United States of America, certifies that they have the skills required to safely perform these biopsies on patients
Experimental: Patients with a suspicious breast mass; Women that present to the hospital with a suspicious breast mass	Procedure: US-guided breast biopsy; During this study, women with undergo an US-guided breast biopsy by a radiologist instead of what is typically performed in Nigerian hospitals, which is either a blind biopsy or surgical excision. US-guided breast biopsy is the standard of care in the United States of America because the accuracy is better than blind biopsy and equal to surgical excision.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Accuracy of US-guided breast biopsy in Nigeria compared to reference standard surgical excision	US-guided breast biopsies accuracy measurements will be reported using surgical pathology as the reference standard. Specifically we will report accuracy, positive predictive value, negative predictive value, sensitivity and specificity.	12 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Complication rates from US-guided breast biopsy compared to reference values reported in the literature.	To determine if the complication rate of US-guided breast biopsies performed by the trained Nigerian radiologists is equivalent to reference values reported in the literature.	12 months
