Global, Regional, and National Cancer Incidence, Mortality, Years of Life Lost, Years Lived With Disability, and Disability-Adjusted Life-Years for 29 Cancer Groups, 1990 to 2017: A Systematic Analysis for the Global Burden of Disease Study.

Importance: Cancer and other noncommunicable diseases (NCDs) are now widely recognized as a threat to global development. The latest United Nations high-level meeting on NCDs reaffirmed this observation and also highlighted the slow progress in meeting the 2011 Political Declaration on the Prevention and Control of Noncommunicable Diseases and the third Sustainable Development Goal. Lack of situational analyses, priority setting, and budgeting have been identified as major obstacles in achieving these goals. All of these have in common that they require information on the local cancer epidemiology. The Global Burden of Disease (GBD) study is uniquely poised to provide these crucial data. Objective: To describe cancer burden for 29 cancer groups in 195 countries from 1990 through 2017 to provide data needed for cancer control planning. Evidence Review: We used the GBD study estimation methods to describe cancer incidence, mortality, years lived with disability, years of life lost, and disability-adjusted life-years (DALYs). Results are presented at the national level as well as by Socio-demographic Index (SDI), a composite indicator of income, educational attainment, and total fertility rate. We also analyzed the influence of the epidemiological vs the demographic transition on cancer incidence. Findings: In 2017, there were 24.5 million incident cancer cases worldwide (16.8 million without nonmelanoma skin cancer [NMSC]) and 9.6 million cancer deaths. The majority of cancer DALYs came from years of life lost (97%), and only 3% came from years lived with disability. The odds of developing cancer were the lowest in the low SDI quintile (1 in 7) and the highest in the high SDI quintile (1 in 2) for both sexes. In 2017, the most common incident cancers in men were NMSC (4.3 million incident cases); tracheal, bronchus, and lung (TBL) cancer (1.5 million incident cases); and prostate cancer (1.3 million incident cases). The most common causes of cancer deaths and DALYs for men were TBL cancer (1.3 million deaths and 28.4 million DALYs), liver cancer (572 000 deaths and 15.2 million DALYs), and stomach cancer (542 000 deaths and 12.2 million DALYs). For women in 2017, the most common incident cancers were NMSC (3.3 million incident cases), breast cancer (1.9 million incident cases), and colorectal cancer (819 000 incident cases). The leading causes of cancer deaths and DALYs for women were breast cancer (601 000 deaths and 17.4 million DALYs), TBL cancer (596 000 deaths and 12.6 million DALYs), and colorectal cancer (414 000 deaths and 8.3 million DALYs). Conclusions and Relevance: The national epidemiological profiles of cancer burden in the GBD study show large heterogeneities, which are a reflection of different exposures to risk factors, economic settings, lifestyles, and access to care and screening. The GBD study can be used by policy makers and other stakeholders to develop and improve national and local cancer control in order to achieve the global targets and improve equity in cancer care.

Breast cancer in South-Eastern European countries since 2000: Rising incidence and decreasing mortality at young and middle ages.

BACKGROUND: Marked variations exist in the incidence and mortality trends of major cancers in South-Eastern European (SEE) countries which have now been detailed by age for breast cancer (BC) to seek clues for improvement. METHODS: We brought together and analysed data from 14 cancer registries (CRs), situated in SEE countries or directly adjacent. Age-standardised rate at world standard (ASRw) and truncated incidence and mortality rates during 2000-2010 by year, and for four age groups, were calculated. Average annual percentage change of rates was estimated using Joinpoint regression. RESULTS: Annual incidence rates increased significantly in countries and age groups, by 2-4% (15-39 years), 2-5% (40-49), 1-4% (50-69) and 1-6% (at 70+). Mortality rates decreased significantly in all age-groups in most countries, but increased up to 5% annually above age 55 in Ukraine, Serbia, Moldova and Cyprus. The BC data quality was evaluated by internationally agreed indicators which appeared suboptimal for Moldova, Bosnia and Herzegovina and Romania. CONCLUSION: The observed variations of incidence trends reflect the influence of risk factors, as well as levels of early detection activities (screening). While mortality rates were mostly decreasing, probably due to improved cancer care and introduction of more effective systemic treatment regimens, the worrying increasing mortality trends in the 55-plus age groups in some countries have to be addressed by health professionals and policymakers. In order to assess and monitor the effects of cancer control activities in the region, the CRs need substantial investments.

Disparities in melanoma incidence and mortality in South-Eastern Europe: Increasing incidence and divergent mortality patterns. Is progress around the corner?

INTRODUCTION: Most countries in South-Eastern Europe (SEE) have lower incidence, but higher mortality rates of malignant melanoma (MM) of the skin compared to North-Western Europe (NWE). We explored trends in MM incidence and mortality in SEE countries by sex and age and compared them with the trends in NWE. METHODS: We obtained data on incident cases and deaths from MM (ICD-10 code C43) from 11 population-based cancer registries in Bosnia and Herzegovina, Bulgaria, Croatia, Cyprus, Czech Republic, Malta, Romania, Serbia, Slovakia, Slovenia and Turkey. We calculated age-specific rates for 25-49 ('young'), 50-69 ('middle aged') and 70+ years ('older') and estimated the average annual percent of change in incidence and mortality trends 2000-2010 according to age group and sex, using joinpoint regression analysis. FINDINGS: The incidence rates of MM across the region were uniformly increasing. Significant increases in mortality rates were observed in middle aged men in Serbia and Bulgaria, middle aged women in Slovenia, older men in the Czech Republic, Serbia and Turkey, and older women in Slovenia and Serbia. INTERPRETATION: While MM incidence rates were still increasing across SEE, mortality trends diverged and were less favourable than in NWE. Empowering cancer registration and improving the quality of incidence and mortality data will be essential for monitoring progress in MM control. In the context of prevention of melanoma, disparities in early detection appear to be widening the gap between SEE and NWE, while the provision of care to patients with advanced disease is likely to prove a challenge for regional healthcare budgets.

Survival variations by country and age for lymphoid and myeloid malignancies in Europe 2000-2007: Results of EUROCARE-5 population-based study.

BACKGROUND: Significant advances in the management of patients with lymphoid and myeloid malignancies entered clinical practice in the early 2000's. The EUROCARE-5 study database provides an opportunity to assess the impact of these changes at the population level by country in Europe. We provide survival estimates for clinically relevant haematological malignancies (HM), using the International Classification of Diseases for Oncology 3, by country, gender and age in Europe. METHODS: We estimated age-standardised relative survival using the complete cohort approach for 625,000 adult patients diagnosed in 2000-2007 and followed up to 2008. Survival information was provided by 89 participating cancer registries from 29 European countries. Mean survival in Europe was calculated as the population weighted average of country-specific estimates. RESULTS: On average in Europe, 5-year relative survival was highest for Hodgkin lymphoma (81%; 40,625 cases), poorest for acute myeloid leukaemia (17%; 57,026 cases), and intermediate for non-Hodgkin lymphoma (59%; 329,204 cases), chronic myeloid leukaemia (53%; 17,713 cases) and plasma cell neoplasms (39%; 94,024 cases). Survival was generally lower in Eastern Europe and highest in Central and Northern Europe. Wider between country differences (>10%) were observed for malignancies that benefited from therapeutic advances, such as chronic myeloid leukaemia, chronic lymphocytic leukaemia, follicular lymphoma, diffuse large B-cell lymphoma and multiple myeloma. Lower differences (<10%) were observed for Hodgkin lymphoma. CONCLUSIONS: Delayed or reduced access to innovative and appropriate therapies could plausibly have contributed to the observed geographical disparities between European regions and countries. Population based survival by morphological sub-type is important for measuring outcomes of HM management. To better inform quality of care research, the collection of detailed clinical information at the population level should be prioritised.

General Practitioners' intention to prescribe and prescribing patterns in selected European settings: The OTCSOCIOMED project.

The aim of this paper is to explore general practitioners' (GPs) prescribing intentions and patterns across different European regions using the Theory of Planned Behavior (TPB). A cross-sectional study was undertaken in selected geographically defined Primary Health Care areas in Cyprus, Czech Republic (CZ), France, Greece, Malta, Sweden and Turkey. Face-to-face interviews were conducted using a TPB-based questionnaire. The number of GP participants ranged from 39 to 145 per country. Possible associations between TPB direct measures (attitudes, subjective norms (SN) and perceived behavioral control (PBC)) and intention to prescribe were assessed by country. On average, GPs thought positively of, and claimed to be in control of, prescribing. Correlations between TPB explanatory measures and prescribing intention were weak, with TPB direct measures explaining about 25% of the variance in intention to prescribe in Malta and CZ but only between 3% and 5% in Greece, Sweden and Turkey. SN appeared influential in GPs from Malta; attitude and PBC were statistically significant in GPs from CZ. GPs' prescribing intentions and patterns differed across participating countries, indicating that country-specific interventions are likely to be appropriate. Irrational prescribing behaviors were more apparent in the countries where an integrated primary care system has still not been fully developed and policies promoting the rational use of medicines are lacking. Demand-side measures aimed at modifying GPs prescribing behavior are deemed necessary.

Irrational prescribing of over-the-counter (OTC) medicines in general practice: testing the feasibility of an educational intervention among physicians in five European countries.

BACKGROUND: Irrational prescribing of over-the-counter (OTC) medicines in general practice is common in Southern Europe. Recent findings from a research project funded by the European Commission (FP7), the "OTC SOCIOMED", conducted in seven European countries, indicate that physicians in countries in the Mediterranean Europe region prescribe medicines to a higher degree in comparison to physicians in other participating European countries. In light of these findings, a feasibility study has been designed to explore the acceptance of a pilot educational intervention targeting physicians in general practice in various settings in the Mediterranean Europe region. METHODS: This feasibility study utilized an educational intervention was designed using the Theory of Planned Behaviour (TPB). It took place in geographically-defined primary care areas in Cyprus, France, Greece, Malta, and Turkey. General Practitioners (GPs) were recruited in each country and randomly assigned into two study groups in each of the participating countries. The intervention included a one-day intensive training programme, a poster presentation, and regular visits of trained professionals to the workplaces of participants. Reminder messages and email messages were, also, sent to participants over a 4-week period. A pre- and post-test evaluation study design with quantitative and qualitative data was employed. The primary outcome of this feasibility pilot intervention was to reduce GPs' intention to provide medicines following the educational intervention, and its secondary outcomes included a reduction of prescribed medicines following the intervention, as well as an assessment of its practicality and acceptance by the participating GPs. RESULTS: Median intention scores in the intervention groups were reduced, following the educational intervention, in comparison to the control group. Descriptive analysis of related questions indicated a high overall acceptance and perceived practicality of the intervention programme by GPs, with median scores above 5 on a 7-point Likert scale. CONCLUSIONS: Evidence from this intervention will estimate the parameters required to design a larger study aimed at assessing the effectiveness of such educational interventions. In addition, it could also help inform health policy makers and decision makers regarding the management of behavioural changes in the prescribing patterns of physicians in Mediterranean Europe, particularly in Southern European countries.

Cancer incidence and mortality patterns in South Eastern Europe in the last decade: gaps persist compared with the rest of Europe.

INTRODUCTION: Cancer registration coverage and cancer control programmes in South Eastern (SE) Europe, embracing about six new EU member states, remain thin, despite a relatively high incidence and mortality burden from avoidable cancers, particularly in males. We assembled the most recent cancer registry data to estimate the burden of the 17 most common cancers in the region, from Slovenia to Cyprus and Malta. METHODS: Data were made available for analysis from Bulgaria, Croatia, Cyprus, Malta, Romania (Cluj County), Serbia, Slovenia and Turkey (Antalya and Izmir provinces). We analysed incidence and mortality of the 17 most common cancers (counts and age-standardised rates, for the most recent year available and for the period 1999-2008). We used Joinpoint regression to quantify recent trends. FINDINGS: For much of SE Europe, there were no marked declines in overall cancer mortality rates during 1999-2008. In men, lung cancer incidence and mortality rates were high compared to other European countries (age-standardised rates (ASRW) of incidence being 50-60/100,000 in most of the countries), and still increasing in Bulgaria, Serbia and Turkey. Prostate cancer incidence rapidly increased throughout the region by 3-12% annually, largely without any clear declines in mortality. Colorectal cancer incidence increased throughout the region, as did mortality especially in Croatia, Serbia and Bulgaria (average annual percentage change (AAPC) 1.5-2%). In women, breast cancer mortality significantly declined in Slovenia, Croatia and Malta (Average Annual Percentage of Change [AAPC] -2%, -1% and -5%, respectively), but not elsewhere. Cervical cancer incidence rates remained very high in Romania, Serbia and Bulgaria (ASRW>20/100,000). INTERPRETATION: Our data confirmed the North West to South East Europe gradient of increasing incidence and mortality rates of tobacco-related cancers, as well as increasing mortality rates of screen-detectable cancers. The lack of decline in overall cancer mortality also indicates suboptimal levels of cancer control in the region.
