Cancer Types Teams
IARC Global Breast Cancer Initiative (GBCI) Team

Starting date: 2023

Work Programme

The International Agency for Research on Cancer (IARC) and the World Health Organization (WHO) have complementary functions and mandates to advance cancer control globally. WHO launched the Global Breast Cancer Initiative (GBCI) on 8 March 2021, aiming to reduce breast cancer mortality by 2.5% per year. To achieve this goal, three pillars and specific targets were established:

  • Pillar 1: Health promotion for early detection
    Target: Achieve diagnosis of at least 60% of invasive cancers at stage I or II

  • Pillar 2: Timely diagnosis
    Target: Evaluation, imaging, tissue sampling, and pathology completed within 60 days

  • Pillar 3: Comprehensive breast cancer management
    Target: At least 80% of patients with breast cancer undergo a full course of multimodality treatment and successfully return home

 

The IARC GBCI Team was established with the objective of improving sharing of information and knowledge that relates to the GBCI, and improving dialogue and coordination with the WHO Cancer Team.

The overall objective of the IARC GBCI Team is to share information, knowledge, and updates on the latest developments regarding the ongoing relevant IARC projects, including sharing with WHO, and facilitating dialogue and coordination between the GBCI partners. The current activities, aligned by theme or GBCI Pillar, include:

Development and dissemination of supporting data and tools

  • Estimated breast cancer burden via the IARC Global Cancer Observatory, which provides information on incidence, mortality, and prevalence for 185 countries or territories
  • Breast cancer mortality trends by age in 70 middle- and high-income countries (via the Cancer Over Time subsite of the Global Cancer Observatory)
  • Reported cancer incidence from high-quality cancer registries around the world via the periodic publication Cancer Incidence in Five Continents
  • Support to cancer registries in less-developed settings via the Global Initiative for Cancer Registry Development (GICR)
  • Breast cancer incidence and survival by stage and age in 70 low- and middle-income countries (SURVCAN-4)
  • Breast cancer prevalence according to phase of care (PrevPhase-1)
  • Estimated intergenerational impact of premature deaths from breast cancer in terms of maternal orphans
  • Cancer Screening in Five Continents (CanScreen5)
  • The World Code Against Cancer Framework and related educational materials for health promoters and frontline health-care professionals
  • The IARC Learning portal (e.g. self-paced learning programme on Improving the Quality of Cancer Screening)
  • Digital atlas on clinical breast examination (CBE), diagnostic mammography and breast ultrasound, and breast pathology (Atlas of Breast Cancer Early Detection)
  • Country-specific breast cancer profiles via the GBCI framework (e.g. Namibia)
  • Data collection for the GBCI Pillar key performance indicators (KPIs)

Activities related to GBCI Pillar 1: Health promotion for early detection

  • Development of standards, recommendations, and studies regarding breast cancer incidence by stage at diagnosis at the population level
  • The World Code Against Cancer Framework and related educational materials for health promoters and frontline health-care professionals
  • Digital atlas on clinical breast examination (CBE), diagnostic mammography and breast ultrasound, and breast pathology (Atlas of Breast Cancer Early Detection)
  • Studies of the patient’s journey to diagnosis, health system barriers to early detection, and breast cancer awareness levels in hospital-based studies in low- and middle-income countries, including across sub-Saharan Africa (ABC-DO: Namibia, Nigeria, South Africa, Uganda, and Zambia) and in eastern Europe and Asia (DEDICA multicountry study: Belarus, Georgia, Kazakhstan, Nepal, the Republic of Moldova, Romania, the Russian Federation, and Uzbekistan)
  • Evaluation of clinical breast examination (CBE) in a randomized trial (https://doi.org/10.1002/cncr.34526)
  • Implementation of a new multilevel strategy to improve access to the early detection and downstream care continuum for vulnerable rural populations in India (Access Cancer Control India; ACCI)
  • Launch of the 1st edition of the Latin America and the Caribbean Code Against Cancer: https://cancer-code-lac.iarc.who.int/en/ and https://d2u7e27yy6nebm.cloudfront.net/wp-content/uploads/2023/10/pr342_E.pdf

Activities related to GBCI Pillar 2: Timely diagnosis

  • IARC multicentre study to evaluate novel technologies to improve breast cancer early diagnosis in limited-resource settings, in India and Uganda
  • Digital atlas on clinical breast examination (CBE), diagnostic mammography and breast ultrasound, and breast pathology (Atlas of Breast Cancer Early Detection)

Activities related to GBCI Pillar 3: Comprehensive breast cancer management

  • Patterns-of-care studies for breast cancer in Morocco, in Nepal, across eastern Europe and Asia (DEDICA multicountry study: Belarus, Georgia, Kazakhstan, Nepal, the Republic of Moldova, Romania, the Russian Federation, and Uzbekistan), and across sub-Saharan Africa (ABC-DO); interventions to improve treatment completion
