Purpose: Late-stage breast cancer detection should be something of the past; however, it is still all too common in low-resource areas, including Peru, where 57% of women diagnosed with cancer are diagnosed at stage III or IV disease. Early detection of breast cancer is feasible in low-resource semirural and rural areas where mammography is rarely accessible. Methods: PATH collaborated with Peruvian health institutions at local, regional, and national levels to design and implement a model of care for the early detection of breast cancer in Peru. The model includes training health promoters for community outreach, professional midwives in clinical breast exam, doctors to perform fine-needle aspiration biopsy sampling with ultrasound to triage, and patient navigators to ensure patients follow through with treatment. Results: In a northern region of Peru, 400 individuals, including health promoters, midwives, doctors, and volunteers, received early-detection training in two phases. In Peru, local health professionals continue to refine and improve methods and materials using locally available resources, and the Peruvian health information system now includes specific breast cancer detection categories. Despite challenges and limited resources, the model is effective, and partnership with government health administrations improves health systems and benefits the population. Conclusion: Given the absence of screening mammography, the public health challenge is to bring breast cancer early detection and diagnostic services closer to women's homes and to ensure appropriate follow-up and care. The model is eminently transferable with appropriate adaptation and should now be tested in other settings within and outside of Peru. [ABSTRACT FROM AUTHOR]

Purpose: Breast cancer (BC) is the most common cancer among women in Latin America, yet many countries lack the capacity to provide early detection and diagnostic services. In Peru, mammograms are not readily available in secondary cities, and 57% of women who are diagnosed with BC are diagnosed with stage III and IV disease. To bring services to women in a northern region of Peru, PATH collaborated with Peruvian health institutions at the local, regional, and national levels to design and implement a strategic algorithm with which to increase the early detection of BC in the absence of mammography. Here, we evaluate the impact of training on the quality of clinical breast exam (CBE), ultrasound triage, and fine-needle aspiration (FNA) sampling and the reading of FNA biopsy for triage-positive women. Methods: Two hundred twenty-four midwives and 15 doctors were included in two-step training in Trujillo, Peru. CBE trainings were performed using anatomic models and patient exams in 2-day sessions. Team discussion with trainers was used to improve skills. Doctors' trainings for FNA sampling were led by two international expert pathologists in 2014 and by a Peruvian expert pathologist in 2016. Then in 2017, 43 pretraining and 50 post-training FNA biopsy samples were evaluated for adequacy and quality of diagnosis. Results: Since the trainings, 14,223 women have received CBE on an opportunistic basis. Midwives refer abnormal cases (n = 281) for follow-up. All doctors felt well trained for CBE and FNA, whereas five of 15 doctors perceived the need for additional ultrasound training. Quality assessment revealed that the adequacy of FNA samples improved from 26% pretraining to 37% post-training. Of the 43 FNA samples, a low concordance with reviewers was observed in the detection of suspicious/carcinoma (6.9% v 13.9%), whereas full concordance was observed after the training, although the numbers were small. Conclusion: In Peru, CBE remains an acceptable and feasible approach if complemented with ultrasound triage and FNA biopsy. Additional efforts are needed to increase coverage through a structured program. Training and continuous monitoring are essential for quality assurance.
