Improving outcomes for women with triple-negative breast cancer in Latin America

(Por favor, mire abajo la versión en español)

Breast cancer is a major and growing public health concern in Latin America. One of the most aggressive and challenging subtypes of breast cancer is triple-negative breast cancer (TNBC), accounting for 13–21% of all breast cancer cases. This report takes a closer look at challenges and opportunities to improve the care of TNBC in Latin America, with a focus on Argentina, Brazil, Chile, Colombia, and Mexico.

TNBC is often diagnosed at a late stage when survival chances are low. Early detection – through self-detection and screening – is vital to improve the chance of survival. Current challenges for early detection of TNBC in Latin America include:

• Low awareness of early signs of breast cancer and fear of diagnosis among women
• Low participation or absence of organized population-based screening programs
• Low perceived quality of primary care and screening services in the public sector

TNBC is the most difficult-to-treat subtype of breast cancer irrespective of stage at diagnosis. Alongside surgery and radiation therapy, chemotherapy used to be the only treatment option in TNBC. The recent introduction of immunotherapy and targeted therapy (for patients with BRCA mutations) is currently changing the treatment landscape. Timely breast diagnostics and appropriate treatment are imperative to increase the survival chances of patients. Current challenges in the areas of diagnostics and treatment of TNBC in Latin America include:

• Poor coordination between provides of diagnostic services and treatment in the public sector
• Shortages of specialized physicians, such as pathologists, oncologists, radiologists
• Lack of availability of new treatments in the public sector
• Slow adoption of new treatment approaches in clinical practice

Broad recommendations to improve the care of TNBC patients in Latin America include efforts to raise health literacy to facilitate early detection, ensure optimal care delivery along the entire patient pathway, and adoption of innovation in clinical practice. Improving the quality of care – from early detection to diagnostics and treatment – has wider positive implications for society, including effects on health systems, work life, family life, the need for informal care, and the economy.
