Adults at risk of pneumococcal disease in France.

BACKGROUND: Immunocompromised patients and those with certain underlying medical conditions are at risk of pneumococcal disease, but in France their vaccine coverage is largely unknown. We aimed to assess the number of adult patients eligible for pneumococcal vaccination in France. METHODS: We conducted an annual cross-sectional study based on retrospective data from the French National Health Data System. Over 2014-2018, we included all adults continuously affiliated to the General health insurance scheme (covering 76% of the population), at risk of pneumococcal disease. Patients were identified with published or newly developed algorithms using diagnoses and reimbursements for hospital stays, medical procedures, and specific treatments, laboratory tests, or medical devices. RESULTS: On January 1, 2018, we identified 4,045,021 at-risk patients (11% increase since 2014). Mean age was 66.1years (55.1% were aged≥65), 51% were men, and 18% had at least two conditions. Of these, 3,634,594 had a chronic medical condition (including 2,617,921 patients treated for diabetes, 616,003 for chronic respiratory disease, 424,223 for heart failure, and 285,214 for chronic liver disease) and 570,035 were immunocompromised (of these, 191,527 were treated with immunosuppressive drugs or biotherapy, 152,255 with chemotherapy for cancer, and 100,604 for HIV). CONCLUSION: These published or newly developed algorithms - which can be used to address other public health issues - identified more than 4 million adults eligible for pneumococcal vaccination in the main health insurance scheme (10% of the studied adult population). This is a first step towards ensuring patients get vaccinated as part of their chronic condition management.

Cancer deaths and cases attributable to lifestyle factors and infections in China, 2013.

BACKGROUND: The burden of cancer in China is high, and it is expected to further increase. Information on cancers attributable to potentially modifiable risk factors is essential in planning preventive measures against cancer. We estimated the number and proportion of cancer deaths and cases attributable to ever-smoking, second-hand smoking, alcohol drinking, low fruit/vegetable intake, excess body weight, physical inactivity, and infections in China, using contemporary data from nationally representative surveys and cancer registries. METHODS: The number of cancer deaths and cases in 2013 were obtained from the National Central Cancer Registry of China and data on most exposures were obtained from the China National Nutrition and Health Survey 2002 or 2006 and Global Adult Tobacco Smoking 2010. We used a bootstrap simulation method to calculate the number and proportion of cancer deaths and cases attributable to risk factors and their corresponding 95% confidence intervals (CIs), allowing for uncertainty in data. RESULTS: Approximately 718 000 (95% CI 702 100-732 200) cancer deaths in men and 283 100 (278 800-288 800) cancer deaths in women were attributable to the studied risk factors, accounting for 52% of all cancer deaths in men and 35% in women. The numbers for incident cancer cases were 952 500 (95% CI 934 200-971 400) in men and 442 700 (437 200-447 900) in women, accounting for 47% of all incident cases in men and 28% in women. The greatest proportions of cancer deaths attributable to risk factors were for smoking (26%), HBV infection (12%), and low fruit/vegetable intake (7%) in men and HBV infection (7%), low fruit/vegetable intake (6%), and second-hand smoking (5%) in women. CONCLUSIONS: Effective public health interventions to eliminate or reduce exposure from these risk factors, notably tobacco control and vaccinations against carcinogenic infections, can have considerable impact on reducing the cancer burden in China.

International trends in lung cancer incidence by histological subtype: adenocarcinoma stabilizing in men but still increasing in women.

OBJECTIVES: Trends in overall lung cancer incidence in different countries reflect the maturity of the smoking epidemic. Further understanding of the underlying causes for trends over time can be gained by assessing the trends by sex and histological subtype. We provide a temporal analysis of lung cancer incidence in 12 populations (11 countries), with a focus on cohort-specific trends for the main histological subtypes (squamous cell carcinomas (SCC), adenocarcinomas (AdC), and small cell carcinoma). MATERIAL AND METHODS: We restrict the analysis to population-based registry data of sufficient quality to provide meaningful interpretation, using data in Europe, North America and Oceania, extracted from successive Cancer Incidence in Five Continents Volumes. Poorly specified morphologies were reallocated to a specified grouping on a population, 5-year period and age group basis. RESULTS: In men, lung cancer rates have been declining overall and by subtype, since the beginning of the study period, except for AdC. AdC incidence rates have risen and surpassed those of SCC (historically the most frequent subtype) in the majority of these populations, but started to stabilize during the mid-1980s in North America, Australia and Iceland. In women, AdC has been historically the most frequent subtype and rates continue to increase in most populations studied. Early signs of a decline in AdC can however be observed in Canada, Denmark and Australia among very recent female cohorts, born after 1950. CONCLUSIONS: The continuing rise in lung cancer among women in many countries reinforces the need for targeted smoking cessation efforts alongside preventive actions.

Cancer incidence and mortality patterns in Europe: estimates for 40 countries in 2012.

INTRODUCTION: Cancer incidence and mortality estimates for 25 cancers are presented for the 40 countries in the four United Nations-defined areas of Europe and for the European Union (EU-27) for 2012. METHODS: We used statistical models to estimate national incidence and mortality rates in 2012 from recently-published data, predicting incidence and mortality rates for the year 2012 from recent trends, wherever possible. The estimated rates in 2012 were applied to the corresponding population estimates to obtain the estimated numbers of new cancer cases and deaths in Europe in 2012. RESULTS: There were an estimated 3.45 million new cases of cancer (excluding non-melanoma skin cancer) and 1.75 million deaths from cancer in Europe in 2012. The most common cancer sites were cancers of the female breast (464,000 cases), followed by colorectal (447,000), prostate (417,000) and lung (410,000). These four cancers represent half of the overall burden of cancer in Europe. The most common causes of death from cancer were cancers of the lung (353,000 deaths), colorectal (215,000), breast (131,000) and stomach (107,000). In the European Union, the estimated numbers of new cases of cancer were approximately 1.4 million in males and 1.2 million in females, and around 707,000 men and 555,000 women died from cancer in the same year. CONCLUSION: These up-to-date estimates of the cancer burden in Europe alongside the description of the varying distribution of common cancers at both the regional and country level provide a basis for establishing priorities to cancer control actions in Europe. The important role of cancer registries in disease surveillance and in planning and evaluating national cancer plans is becoming increasingly recognised, but needs to be further advocated. The estimates and software tools for further analysis (EUCAN 2012) are available online as part of the European Cancer Observatory (ECO) (http://eco.iarc.fr).

Prostate cancer incidence and mortality trends in 37 European countries: an overview.

Prostate cancer has emerged as the most frequent cancer amongst men in Europe, with incidence increasing rapidly over the past two decades. Incidence has been uniformly increasing in the 24 countries with comparable data available, although in a few countries with very high rates (Sweden, Finland and The Netherlands), incidence has begun to fall during the last 3-4 years. The highest prostate cancer mortality rates are in the Baltic region (Estonia, Latvia and Lithuania) and in Denmark, Norway and Sweden. Prostate cancer mortality has been decreasing in 13 of the 37 European countries considered - predominantly in higher-resource countries within each region - beginning in England and Wales (1992) and more recently in the Czech Republic (2004). There was considerable variability in the magnitude of the annual declines, varying from approximately 1% in Scotland (from 1994) to over 4% for the more recent declines in Hungary, France and the Czech Republic. There appears little relation between the extent of the increases in incidence (in the late 1990s) and the recent mortality declines. It remains unclear to what extent the increasing trends in incidence indicate true risk and how much is due to detection of latent disease. The decreasing mortality after 1990 may be attributable to improvements in treatment and to an effect of prostate specific antigen (PSA) testing. The increase in mortality observed in the Baltic region and in several Central and Eastern European countries appear to reflect a real increase in risk and requires further monitoring.
