The Breast Health Global Initiative (BHGI) brought together international breast cancer experts to discuss breast cancer in low resource countries (LRCs) and identify common concerns reviewed in this consensus statement. There continues to be a lack of public and health care professionals' awareness of the importance of early detection of breast cancer. Mastectomy continues to be the most common treatment for breast cancer; and a lack of surgeons and anesthesia services was identified as a contributing factor in delayed surgical therapy in LRCs. Where available, radiation therapy is still more likely to be used for palliation rather than for curative treatment. Tumor receptor status is often suboptimally performed due to lack of advanced pathology services and variable quality control of tissue handling and processing. Regional pathology services can be a cost-effective approach and can serve as reference, training and research centers. Limited availability of medical oncologists in LRCs often results in non-specialist providing chemotherapeutic services, which requires additional supervision and training. Palliative care is an emerging field in LRCs that requires investment in training and infrastructure development. A commitment and investment in the development of breast cancer care services by LRC governments and health authorities remains a critical need in LRCs.
ResumenObjetivo. Caracterizar el diagnóstico y tratamiento de mujeres con cáncer de mama en Bogotá, Colombia; establecer la demora de pacientes en la asistencia a consulta y los factores relacionados. Material y Métodos. A través de una aproximación censal se identificaron 1 106 mujeres con cáncer de mama. La recolección de información se hizo mediante entrevistas y revisión de historias clínicas. Se consideró demora de la paciente el tiempo entre la percepción del síntoma y la primera consulta. Resultados. Más de 80% de las mujeres consultaron por síntomas; la mayoría eran estados avanzados. Los factores que se relacionaron con la demora fueron una mayor edad, no tener afiliación al sistema de salud y la enfermedad avanzada. Una mayor educación se relacionó con menor demora. Discusión. Las mujeres no reconocen los síntomas del cáncer de mama; es necesario diseñar estrategias de comunicación y educación para estimular el reconocimiento de los síntomas y la oportunidad de consulta.
The lack of breast cancer screening in low and middle‐income countries results in later stage diagnosis and worsened outcomes for women. A cluster randomized trial was performed in Bogotá, Colombia between 2008 and 2012 to evaluate effects of opportunistic breast cancer screening. Thirteen clinics were randomized to an intervention arm and 13 to a control arm. Physicians in intervention clinics were instructed to perform clinical breast examination on all women aged 50–69 years attending clinics for non‐breast health issues, and then refer them for mammographic screening. Physicians in control clinics were not explicitly instructed to perform breast screening or mammography referrals, but could do so if they thought it indicated (“usual care”). Women were followed for 2‐years postrandomization. 7,436 women were enrolled and 7,419 (99.8%) screened in intervention clinics, versus 8,419 enrolled and 1,108 (13.1%) screened in control clinics. Incidence ratios (IR) of early, advanced and all breast cancers were 2.9 (95% CI 1.1–9.2), 1.0 (0.3–3.5) and 1.9 (0.9–4.1) in the first (screening) year of the trial, and the cumulative IR for all breast cancers converged to 1.4 (0.7–2.8) by the end of follow‐up (Year 2). Eighteen (69.2%) of 26 women with early stage disease had breast conservation surgery (BCS) versus 6 (42.5%) of 14 women with late‐stage disease (p = 0.02). Fifteen (68.2%) of 22 women with breast cancer in the intervention group had BCS versus nine (50.0%) of 18 women in the control group (p = 0.34). Well‐designed opportunistic clinic‐based breast cancer screening programs may be useful for early breast cancer detection in LMICs.
Breast cancer is increasing in developing countries, and Colombia has a double burden from cervical and breast cancer. Suitable guidelines for breast cancer early detection are needed, and the Breast Health Global Initiative provides a favorable framework for breast cancer control in low resource nations. The Colombian National Cancer Institute developed evidence-based guidelines for breast cancer early detection in which coordinated early detection in symptomatic women and hospital-based screening in women aged 50–69 are recommended. A pilot project to evaluate programmatic approaches (opportunistic screening) was designed, and it is expected that organized hospital-based screening for breast cancer will represent a move towards population-based screening in the near future in accordance with country specific conditions.
