As the reference source for global cancer statistics, the Cancer Surveillance Branch (CSU) supports cancer registry development, develops and disseminates global indicators, and conducts a research programme aligned with the evolving cancer and development agendas. CSU is involved in many collaborative studies seeking to describe and interpret the changing magnitude and the transitional nature of cancer profiles around the world, through observation of variations by geography and over time.
During the COVID-19 pandemic, IARC became a founding partner of both the COVID-19 and Cancer Taskforce and the COVID-19 and Cancer Global Modelling Consortium (CCGMC). The CCGMC brings together the global modelling community to support decision-making in cancer control both during and after the crisis.
Current areas of research within CSU include the following:
- Excess deaths from colorectal cancer in high-income countries: modelling the impact of worsening stage.
- Systematic reviews, including critical appraisal, of the early literature:
- Do people with a pre-existing cancer diagnosis have a higher risk of contracting SARS-CoV-2 or developing COVID-19?
- Do COVID-19 patients with cancer have a higher risk of death from COVID-19 than COVID-19 patients without cancer?
- Changes in smoking behaviour during the COVID-19 pandemic.
- SURVMARK. Provision of up-to-date survival measures, and systematic approaches to understanding the impacts of registry processes and stage.
- SURVCAN. Global synthesis of comparable survival statistics in LMICs, with an emphasis on bilateral collaborations with registries to ensure complete follow-up of patients.
- SURVPOOL. Provision of evidence on the impact of major risk factors on cancer survival.
- Cancer attributable fractions for prevention. Studies quantifying the proportion of cases attributable to risk factors.
- Estimation of the burden of cancer using disability-adjusted life years (DALYs).
- Gains in (healthy) life expectancy. The assessment of gains in life expectancy through hypothetical elimination of cancer.
- Prevalence by phase of care. A global update of methods to better identify the needs of cancer patients and attach economic costs.
- Meeting global noncommunicable disease (NCD) targets. Using mortality trends to predict future premature deaths from cancer and other NCDs, as well as the contribution of risk factors and prevention strategies in achieving United Nations Sustainable Development Goals targets.
- Dynamic models to predict the long-term future burden under scenarios of roll-out of screening and vaccination programmes.
- Tobacco control and alcohol control: impact of prevention policies on the long-term burden of related cancers.
- The Cancer Risk in Childhood Cancer Survivors (CRICCS) project, funded by Children with Cancer UK, aims to better understand causes, to lead to targeted prevention strategies, by assessing the risk of second primary neoplasms in survivors of childhood cancer in Europe.
- St. Jude Children’s Research Hospital and IARC launched a bilateral collaborative agreement called Targeting Childhood Cancer through the Global Initiative for Cancer Registry Development (ChildGICR), which includes the following broad research areas:
- barriers to data sharing and the development of best practices;
- classification of childhood central nervous system tumours, and registration of non-malignant central nervous system tumours;
- the financial burden borne by families affected by cancer in a child; and
- quantification of the cost of registration of cancer in children.
- Descriptive epidemiology of social inequalities in cancer (the SOCINEQ project), including assessment of social inequalities in cancer between and within countries and over time, and projections of social inequalities in cancer into the future.
- Identifying modifiable factors underlying the association between inequalities and cancer, and quantifying the avoidable cancer burden through addressing social inequalities.
- The economic costs of thyroid cancer overdiagnosis and overtreatment (the THYCOST project).
- Estimation of productivity losses due to cancer-related premature mortality at the global, regional, and national levels.
- Systematic reviews on financial hardship experienced by cancer patients for both adult and childhood cancers, with a focus on catastrophic out-of-pocket expenditures in LMICs.
- Priority-setting in cancer prevention and control. Working with WHO to assist national policy-makers to obtain the best value for money by identifying priority interventions in cancer planning and evaluating the impact, cost, and feasibility of a package of interventions according to country capacity.

GLOBOCAN. The global estimates for 2020 are included in the Cancer Today subsite of the Global Cancer Observatory. These estimates will be updated every 2 years, based on the most recently available recorded data worldwide. The release of new estimates is accompanied by an open access article assessing regional variations in cancer incidence and mortality.
