CONCORD Programme

CONCORD Logo final

CONCORD is the programme for world-wide surveillance of trends in cancer survival, led by the London School of Hygiene & Tropical Medicine. The CONCORD programme is endorsed by 40 national and international agencies, including WHO EURO, the Organisation for Economic Co-operation & Development (OECD) and the World Bank.

The CONCORD Steering Committee includes scientists and cancer patients from 13 countries, with expertise in biostatistics, epidemiology, cancer registration and public health.

The third cycle of the programme, CONCORD-3, has updated the global  surveillance of trends in cancer survival to include patients diagnosed up to 2014 in more than 70 countries. The results cover 18 of the most common cancers. These cancers represent 75% of all the cancers diagnosed world-wide each year.

The summary article for CONCORD-3 was published in The Lancet in 2018.

The abstract of the article is available here in English and 10 other languages: Arabic, Chinese, French, German, Italian, Japanese, Portuguese, Russian, Spanish and Turkish.

CONCORD survival estimates are used by OECD, the European Union and the World Health Organisation

The Organisation for Economic Co-operation and Development  collaborates with the CONCORD programme to develop Healthcare Quality Indicators of Cancer Care.

This is designed to improve the capacity of countries to monitor the effectiveness of their health systems in delivering high-quality cancer care.

The Organisation for Economic Co-operation and Development  has included survival estimates from the CONCORD programme for 48 countries in its Health at a Glance publications since 2017.

This is formal recognition by an international agency of the global coverage, methodological rigour and international comparability of the CONCORD survival estimates.

CONCORD results have also been used in the European Union’s new Country Health Profiles as part of the State of Health in the EU initiative, by the World Health Organisation to examine the impact of the pricing of the medicines for cancer prevention and treatment, and in a Lancet Oncology Commision on the long-term economic benefit of delivering sustainable care for children with cancer around the world.


Why global surveillance of cancer survival?

The global burden of cancer is growing, especially in countries of low and middle income. Hence, the need for effective strategies of primary prevention is urgent. Prevention is crucial, but long-term. WHO‘s global target of a 25% reduction in deaths from cancer and other non-communicable diseases in people aged 30–69 years by 2025 (“25 × 25”), requires not just more effective prevention to reduce incidence, but also more effective health systems to improve survival.

Global surveillance of cancer incidence (IARC) and cancer mortality (WHO) has been in progress for over 50 years. The CONCORD-2 study has now initiated global surveillance of cancer survival, the third key metric of cancer control.

Information on the survival of all cancer patients in a population enables comparison of the effectiveness of health systems. Long-term surveillance will contribute to the evidence base for global policy on cancer control. CONCORD will monitor progress towards the overarching goal of the UICC World Cancer Declaration 2013: “major reductions in premature deaths from cancer, and improvements in quality of life and cancer survival”. This should greatly improve prospects for global cancer control.


CONCORD-2

The CONCORD-2 study, published in The Lancet (2015), extended coverage to 25.7 million adults (15-99 years) diagnosed during the 15 years 1995-2009 with a cancer of the stomach, colon, rectum, liver, lung, breast (women), cervix, ovary or prostate, or leukaemia, and 75,000 children (0-14 years) with acute lymphoblastic leukaemia. Individual data on all these patients were submitted by 279 population-based cancer registries in 67 countries – 40 with national coverage of their population. Patients were followed up to 31 December 2009.

The 10 cancers examined in CONCORD-2 represent two-thirds (63%) of the overall cancer burden in both low-income, middle-income and high-income countries. The 67 participating countries are home to two-thirds of the world’s population.


The first CONCORD study

The first CONCORD study, published in The Lancet Oncology (2008), was the first global comparison of population-based cancer survival. It showed wide variation in survival from cancers of the breast (women), colon, rectum and prostate among 1.9 million adults diagnosed during 1990-1994 and followed up to 1999 in 31 countries (16 with national coverage).

Quality control and analysis

Standardised quality control procedures were applied. Errors were corrected by the registry concerned. Five-year net survival estimates were adjusted for background mortality by single year of age, sex, calendar year, and where possible, race, for each country or region. Survival estimates were age-standardised with the International Cancer Survival Standard weights.


Main findings

Five-year survival from colon, rectal and breast cancers has increased in most developed countries. Liver and lung cancer remain lethal in most countries. Striking increases in prostate cancer survival have occurred in many countries, but trends vary widely. The range in cervical and ovarian cancer survival is very wide, but there have been slight improvements. In Eastern Asia, stomach cancer survival is very high, but survival for adult and childhood leukaemia is remarkably low. The global range in survival from childhood leukaemia is very wide, suggesting major deficiencies in the management of what is now considered to be a largely curable disease.
