Objective. To present the most recent national estimates of lung cancer burden globally in 185 countries and tobacco smoking prevalence (%) by sex. Materials and methods. Estimates of lung cancer incidence and mortality for 2018 were extracted from the Globocan database; observed incidence, from the last volume of Cancer Incidence in Five Continents, and tobacco prevalence, from the World Health Observatory/WHO database. Results. In 2018, over two million new lung cancer cases and 1.7 million deaths were estimated to occur worldwide, representing 14% of the new cancer cases and 20% of the cancer deaths. Incidence rates showed marked variation between countries. Stable or decreasing incidence rates were predominant among males, while among females increasing rates were common. Con­clusion. The continuing rise in lung cancer among women reinforces the need for strengthening implementation of the preventive actions committed to by governments in the WHO Framework Convention for Tobacco Control.

PURPOSE: Worldwide, Indigenous people often have disproportionally worse health and lower life expectancy than their non-Indigenous counterparts. Despite the impact of cancer on life expectancy, little is known about the burden of cancer for Indigenous people primarily because of the paucity of data. We investigated the collection and reporting of Indigenous status information among a global sample of population-based cancer registries (PBCRs). PARTICIPANTS AND METHODS: An online survey was e-mailed to eligible registries using set inclusion criteria. Respondents were asked questions on the collection, reporting, and quality assessment of Indigenous status in their registers. RESULTS: Eighty-three PBCRs from 25 countries were included. Of these, 66% reported that their registry collected Indigenous status data, although the quality of this variable had been assessed in less than half in terms of completeness (38%) and accuracy (47%). Two thirds of PBCRs who collected Indigenous status data (67%), from nine of 25 countries responded that cancer statistics for Indigenous people were reported using registry data. Key barriers to the collection of Indigenous status information included the lack of data collection at the point of care (79%), lack of transfer of Indigenous status to the cancer registry (46%), inadequate information systems (43%), and legislative limitations (32%). Important variations existed among world regions, although the lack of Indigenous status data collection at the point of care was commonly reported across all regions. CONCLUSION: High-quality data collection is lacking for Indigenous peoples in many countries. To ensure the design and implementation of cancer control activities required to reduce disparities for Indigenous populations, health information systems, including cancer registries, need to be strengthened, and this must be done in dialogue with Indigenous leaders.

The Global Initiative for Cancer Registry Development partnership, led by the International Agency for Research on Cancer (IARC), was established in response to an overwhelming need for high-quality cancer incidence data from low-income and middle-income countries. The IARC Regional Hub for cancer registration in North Africa, Central and West Asia was founded in 2013 to support capacity building for cancer registration in each of the countries in this region. In this Series paper, we advocate the necessity for tailored approaches to cancer registration given the rapidly changing cancer landscape for this region, and the challenges faced at a national level in developing data systems to help support this process given present disparities in resources and health infrastructure. In addition, we provide an overview of the status of cancer surveillance and activities country-by-country, documenting tailored approaches that are informing local cancer-control policy, and potentially curbing the growing cancer burden across the region.

INTRODUCTION: Europe is an important focus for compiling accurate and up-to-date world cancer statistics owing to its large share of the world's total cancer burden. This article presents incidence and mortality estimates for 25 major cancers across 40 individual countries within European areas and the European Union (EU-27) for the year 2020. METHODS: The estimated national incidence and mortality rates are based on statistical methodology previously applied and verified using the most recently collected incidence data from 151 population-based cancer registries, mortality data and 2020 population estimates. RESULTS: Estimates reveal 4 million new cases of cancer (excluding non-melanoma skin cancer) and 1.9 million cancer-related deaths. The most common cancers are: breast in women (530,000 cases), colorectum (520,000), lung (480,000) and prostate (470,000). These four cancers account for half the overall cancer burden in Europe. The most common causes of cancer deaths are: lung (380,000), colorectal (250,000), breast (140,000) and pancreatic (130,000) cancers. In EU-27, the estimated new cancer cases are approximately 1.4 million in males and 1.2 million in females, with over 710,000 estimated cancer deaths in males and 560,000 in females. CONCLUSION: The 2020 estimates provide a basis for establishing priorities in cancer-control measures across Europe. The long-established role of cancer registries in cancer surveillance and the evaluation of cancer control measures remain fundamental in formulating and adapting national cancer plans and pan-European health policies. Given the estimates are built on recorded data prior to the onset of coronavirus disease 2019 (COVID-19), they do not take into account the impact of the pandemic.

Cancer is a leading cause of death in small island nations and is forecast to increase substantially over the coming years. Governments, regional agencies, and health services of these nations face daunting challenges, including small and fragile economies, unequal distribution of resources, weak or fragmented health services, small population sizes that make sustainable workforce and service development problematic, and the unavailability of specialised cancer services to large parts of the population. Action is required to prevent large human and economic costs relating to cancer. This final Series paper highlights the challenges and opportunities for small island nations, and identifies ways in which the international community can support efforts to improve cancer control in these settings. Our recommendations focus on funding and investment opportunities to strengthen cancer-related health systems to improve sharing of technical assistance for research, surveillance, workforce, and service development, and to support small island nations with policy changes to reduce the consumption of commodities (eg, tobacco and unhealthy food products) that increase cancer risk.

Background: Population-based cancer survival estimates provide valuable insights into the effectiveness of cancer services and can reflect the prospects of cure. As part of the second phase of the International Cancer Benchmarking Partnership (ICBP), the Cancer Survival in High-Income Countries (SURVMARK-2) project aims to provide a comprehensive overview of cancer survival across seven high-income countries and a comparative assessment of corresponding incidence and mortality trends. Methods: In this longitudinal, population-based study, we collected patient-level data on 3·9 million patients with cancer from population-based cancer registries in 21 jurisdictions in seven countries (Australia, Canada, Denmark, Ireland, New Zealand, Norway, and the UK) for seven sites of cancer (oesophagus, stomach, colon, rectum, pancreas, lung, and ovary) diagnosed between 1995 and 2014, and followed up until Dec 31, 2015. We calculated age-standardised net survival at 1 year and 5 years after diagnosis by site, age group, and period of diagnosis. We mapped changes in incidence and mortality to changes in survival to assess progress in cancer control. Findings: In 19 eligible jurisdictions, 3 764 543 cases of cancer were eligible for inclusion in the study. In the 19 included jurisdictions, over 1995–2014, 1-year and 5-year net survival increased in each country across almost all cancer types, with, for example, 5-year rectal cancer survival increasing more than 13 percentage points in Denmark, Ireland, and the UK. For 2010–14, survival was generally higher in Australia, Canada, and Norway than in New Zealand, Denmark, Ireland, and the UK. Over the study period, larger survival improvements were observed for patients younger than 75 years at diagnosis than those aged 75 years and older, and notably for cancers with a poor prognosis (ie, oesophagus, stomach, pancreas, and lung). Progress in cancer control (ie, increased survival, decreased mortality and incidence) over the study period was evident for stomach, colon, lung (in males), and ovarian cancer. Interpretation: The joint evaluation of trends in incidence, mortality, and survival indicated progress in four of the seven studied cancers. Cancer survival continues to increase across high-income countries; however, international disparities persist. While truly valid comparisons require differences in registration practice, classification, and coding to be minimal, stage of disease at diagnosis, timely access to effective treatment, and the extent of comorbidity are likely the main determinants of patient outcomes. Future studies are needed to assess the impact of these factors to further our understanding of international disparities in cancer survival.
