What if cancer survival in Britain were the same as in Europe: how many deaths are avoidable?

OBJECTIVE: To estimate the number of deaths among cancer patients diagnosed in Great Britain that would be avoidable within 5 years of diagnosis if the mean (or highest) survival in Europe for patients diagnosed during 1985-1989, 1990-1994 and 1995-1999 were achieved. DESIGN: Five-year relative survival for cancers in Great Britain compared with that from other countries in the EUROCARE-2, -3 and -4 studies. Calculation of excess deaths (those more than expected from mortality in the general population) that would be avoidable among cancer patients in Britain if relative survival were the same as in Europe. SETTING: Great Britain (England, Wales, Scotland) and 13 other European countries. SUBJECTS: 2.8 million adults diagnosed in Britain with 1 of 39 cancers during 1985-1989 (followed up to 1994), 1990-1994 (followed up to 1999) and 1995-1999 (followed up to 2003). MAIN OUTCOME MEASURE: Annual number of avoidable deaths within 5 years of diagnosis. Percentage of the excess (cancer-related) deaths among cancer patients that would be avoidable. RESULTS: Compared with the mean European 5-year relative survival, the largest numbers of avoidable deaths for patients diagnosed during 1985-1989 were for cancers of the breast (about 18% of the excess mortality from this cancer, 7541 deaths), prostate (14%, 4285), colon (9%, 4090), stomach (8%, 3483) and lung (2%, 3548). For 1990-1994, the largest numbers of avoidable deaths were for cancers of the prostate (20%, 7335), breast (15%, 6165), colon (9%, 4376), stomach (9%, 3672), lung (2%, 3735) and kidney (22%, 2644). For 1995-1999, most of the avoidable deaths were for cancers of the prostate (17%, 5758), breast (15%, 5475), lung (3%, 4923), colon (10%, 4295), stomach (9%, 3137) and kidney (21%, 2686).Overall, some 6600-7500 premature deaths would have been avoided each year among cancer patients diagnosed in Britain during 1985-1999 if the mean survival in Europe had been achieved. This represents 6-7% of cancer-related mortality. Compared with the highest European survival, avoidable premature mortality among cancer patients fell from about 12 800 deaths a year (12.2% of cancer-related mortality) to about 11 400 deaths a year (10.6%) over the same period.A large component of the avoidable mortality is due to prostate cancer: excluding this cancer from comparison with the European mean survival reduces the annual number of avoidable deaths by 1000-1500, and the percentage of excess mortality by up to 1%. Compared with the highest survival, the annual number of avoidable deaths would be 1500-2000 fewer, and 1-2% lower as a percentage of excess mortality, but the overall trend in avoidable premature mortality among cancer patients would be similar, falling from 11.4% (1985-1989) to 10.3% (1990-1994) and 9.7% for those diagnosed during 1995-1999.For several cancers, survival in Britain was slightly higher than the mean survival in Europe; this represented some 110-180 premature deaths avoided each year during the period 1985-2003. CONCLUSIONS: Avoidable premature mortality among cancer patients diagnosed in Britain during 1985-1999 has represented 6-7% of cancer-related mortality compared with the mean survival in Europe. Compared with the highest levels of survival in Europe, the reduction from 12.2% to 10.6% of cancer-related mortality reflects small but steady progress over the period 1985-2003

Lower incidence rates but thicker melanomas in Eastern Europe before 1992: A comparison with Western Europe

The objective of this study was to investigate the epidemiology of melanoma across Europe with regard to Breslow thickness and body-site distribution. Incidence data from Cancer Incidence in 5 Continents and the EUROCARE-melanoma database were used: 28 117 melanoma cases from 20 cancer registries in 12 European countries, diagnosed between 1978 and 1992. Regression analysis and general linear modelling were used to analyse the data. Melanomas in Eastern Europe were on average 1.4 mm thicker (P<0.05) than in Western Europe and appeared more often on the trunk. From 1978 to 1992, their Breslow thickness had decreased in Western but not Eastern Europe. There was a latitude gradient in incidence, with highest rates in southern regions in Eastern Europe and an inverse gradient in Western Europe, with highest rates in the North. Mortality:incidence ratios were less favourable in southern parts across Europe, especially in Eastern Europe. If Eastern European populations copy the sunbathing behaviour of the West it is likely that in the near future a higher melanoma incidence can be expected there

Improved clinical investigation and evaluation of high-risk medical devices: the rationale and objectives of CORE-MD (Coordinating Research and Evidence for Medical Devices)

: In the European Union (EU) the delivery of health services is a national responsibility but there are concerted actions between member states to protect public health. Approval of pharmaceutical products is the responsibility of the European Medicines Agency, whereas authorizing the placing on the market of medical devices is decentralized to independent 'conformity assessment' organizations called notified bodies. The first legal basis for an EU system of evaluating medical devices and approving their market access was the medical device directives, from the 1990s. Uncertainties about clinical evidence requirements, among other reasons, led to the EU Medical Device Regulation (2017/745) that has applied since May 2021. It provides general principles for clinical investigations but few methodological details-which challenges responsible authorities to set appropriate balances between regulation and innovation, pre- and post-market studies, and clinical trials and real-world evidence. Scientific experts should advise on methods and standards for assessing and approving new high-risk devices, and safety, efficacy, and transparency of evidence should be paramount. The European Commission recently awarded a Horizon 2020 grant to a consortium led by the European Society of Cardiology and the European Federation of National Associations of Orthopaedics and Traumatology, that will review methodologies of clinical investigations, advise on study designs, and develop recommendations for aggregating clinical data from registries and other real-world sources. The CORE-MD project (Coordinating Research and Evidence for Medical Devices) will run until March 2024; here we describe how it may contribute to the development of regulatory science in Europe

A wide difference in cancer survival between middle aged and elderly patients in Europe.

Abstract Nowadays the burden of cancer in elderly people has reached an alarming extent. The purpose of this study is comparing cumulative and conditional relative survival in elderly patients between 65 and 84 years and younger adults aged from 55 to 64. Fifty-three cancer registries of 22 European countries, participating in the EUROCARE-3 programme, collected information on the cases diagnosed over the period 1990-1994. We computed cumulative and conditional relative survival for 16 cancer sites. Middle aged patients experienced a better prognosis than the elderly for all cancer sites, in both sexes and the differences were more marked at 1 than 5 years since diagnosis. The very large differences noted in the first period after cancer detection declined in the subsequent years and, when 5-years conditional survival was considered, for several cancers the elderly and younger adults had the same probabilities of surviving. The death relative excess risks (RERs) in the elderly with respect younger individuals were really very high and markedly larger at 1 than 5 years, and in women than men. Genitourinary and gynaecological cancers showed the highest RERs, around 2.0 and between 1.5 and 2.5 respectively. This very high early mortality could be due not only to clinical aspects: the barriers to health care access and a consequent late diagnosis might represent for elderly patients the main determinant of this very large prognostic disadvantage. In conclusion, clinical management of cancer in the elderly remains a major issue to be faced with complex social and health care policies

Seventeen-year trend (2001\u20132017) in pacemaker and implantable cardioverter-defibrillator utilization based on hospital discharge database data: An analysis by age groups

Aims: To analyze temporal trends (2001 -2017) of Pacemakers (PM) and Implantable Cardioverter-Defibrillators (ICD) procedures in Italy, according to the national Hospital Discharge Database (HDD). Methods: Frequency and implant rate (IR) in the Italian population were analyzed by age groups (<50, 50\u201379, 6580 years). Results: From 2001 (2009 for Cardiac Resynchronization Therapy-Defibrillator \u2013 CRT-D) to 2017, first PM implants (1stPM) increased from 36,823 (637/million inhabitants) to 49,716 (820/million), ICD implants from 3,141 (54/million) to 24,255 (400/million) and CRT-D from 2,915 (49/million, 16.5% of ICD) to 8,595 (142/million, 35.4% of ICD). ICD implants due to ventricular tachycardia or ventricular fibrillation decreased from 55.6% to 13.5% and from 15.9% to 4.5% respectively, while the proportion increased among patients with heart failure (from 22.9% to 46.8%), hypertension (from 11.1% to 15.0%), diabetes (from 6.5% to 10.9%), and renal insufficiency (from 4.4% to 7.6%). Both PM and ICD procedures markedly increased in patients 6580 years old. However, while IR for ICDs increased from 82/million to 1,038/million inhabitants, IR of 1stPM only changed from 6,111/million to 6,212/million as the population in this age group nearly doubled in Italy. Conclusion: Since 2001, the increase of 1stPM in Italy was mainly due to the ultra-octogenarian population growth. No differences were observed for IR in each PM age group, while the absolute number and IR increased in all groups (especially 6580 years old) for ICDs and CRT-Ds. An increase in comorbidities and a reduction in implants for secondary prevention were observed in the ICD population

Electronic availability of EUROCARE-3 data: a tool for further analysis.

The EUROCARE-3 CD-ROM has been developed to provide more detailed data with respect to those published in the monograph. The CD-ROM provides estimates of age-specific and age-standardised survival figures, cumulative and interval-specific survival, observed and relative survival for 47 cancer sites or combinations of sites, based on >4 million adult cancer patients diagnosed from 1983 to 1994 and reported from 56 European cancer registries. In addition, the CD-ROM provides observed survival proportions for 25 childhood cancer entities based on 23,000 young patients diagnosed from 1990 to 1994. Survival indicators, corresponding standard errors and confidence intervals can be selected according to cancer site, registry or country, sex, age class and disease duration. Basic graphical display and export facilities have also been provided. As an example of how to use this CD-ROM, this paper will report a descriptive analysis of relative survival patterns for all cancers combined, by age, sex and country. The EUROCARE-3 CD-ROM can be ordered free of charge or directly downloaded at http://www.eurocare.it

Design and implementation of the new Italian healthcare digital interoperable registry for implantable medical devices

Nowadays, the role played by registries in monitoring and improving healthcare, including the quality of medical devices, is widely recognized. A well-designed digital healthcare registry, in particular regarding data collection procedures and tools, can effectively support goals such as monitoring a (large) population subject to a specific condition, describing the natural history of diseases, supporting observational study methods, as well as evaluating the clinical effectiveness or cost effectiveness of healthcare products and services. This article describes the architecture of a new platform implementing a digital interoperable healthcare registry, the Italian Implantable Prostheses Registry (RIPI). One of the main goals of RIPI is to provide reliable and high-quality data for monitoring surgery outcomes, performing survival analysis, assessing the safety of devices and procedures, and supporting the traceability of patients. The article focuses on the key aspects and choices that guided the design and implementation processes of the new platform. Most of the design choices came from specific requirements to fulfill, in particular concerning data quality, access policy, interoperability, extensibility and modularity. Overall, the article discusses the main challenges and the adopted solutions, proposing a design perspective and describing an experience of interest for computer scientists, engineers and practitioners, in particular in the area of healthcare information systems

Italian Arthroplasty Registry. Annual Report 2018 – Addendum. Excerpt from: Registro Italiano ArtroProtesi. Report Annuale 2018

The publication of the Addendum to RIAP Annual Report 2018 in English is aimed at supporting the international dissemination of the results achieved by the Italian Arthroplasty Registry. From 2018 on, the Annual Report (the full version of the report is only available in Italian) is entirely dedicated to the activities carried out by RIAP team, focusing exclusively on the data collected by RIAP. Tables and figures resulting from the HDD analysis, presented in previous editions have been excluded from this year issue and are the subject of a separate analysis. The only legacy table included in this year’s Addendum, portrays the total number of joint replacements carried out in Italy in the period 2001-2016 along with the 2017 estimate for hip, knee, and shoulder joints (Appendix 2B). The structure of the Report has become therefore more agile and stretches through two chapters (no longer five). Chapter 1 summarizes the activities of RIAP in 2017-2018. Chapter 2 is dedicated to the analysis of RIAP data of 2017 and reports the measurement of coverage and completeness of the participating institutions. Likewise, the English Addendum has also been reworked. The document now includes a comprehensive Executive Summary divided into five paragraphs (About RIAP, RIAP in 2017-2018: progress and key achievements, Key findings from the Annual Report 2018, Challenges, Future development and plans for 2019) followed by the tables and figures relating to the analysis of the RIAP data collected in 2017

The EUROCARE-3 database: methodology of data collection, standardisation, quality control and statistical analysis.

The EUROCARE database contains data on 6.5 million cancer patients diagnosed from 1978 to 1994 in populations covered by 67 cancer registries in 22 European countries. The quality-checked entries specify age, sex, diagnosis date, cancer site, morphology, microscopic confirmation and vital status, as well as containing broad indicators of stage. For EUROCARE-3, which refers to diagnoses from 1990 to 1994, 3389 cases with major data problems and 142,525 second or subsequent cancers were removed, leaving more than 2 million cases for analysis. From these data, observed and relative survival for each cancer site and country were calculated at 1, 3 and 5 years from diagnosis. Overall European survival for each cancer site and for all cancers combined were calculated combining country-specific survival figures. Overall, 1.1% of cases were lost to follow-up, 4.2% were known from death certificates only and 1.2% were known at autopsy only. The percentage of microscopically confirmed cases varied with cancer site and country, and was always higher in northern European countries. Comparison of quality indicators for the EUROCARE-3 database with earlier EUROCARE databases indicates that data quality and standardisation have improved

Multiple tumours in survival estimates.

Abstract In international comparisons of cancer registry based survival it is common practice to restrict the analysis to first primary tumours and exclude multiple cancers. The probability of correctly detecting subsequent cancers depends on the registry's running time, which results in different proportions of excluded patients and may lead to biased comparisons. We evaluated the impact on the age-standardised relative survival estimates of also including multiple primary tumours. Data from 2,919,023 malignant cancers from 69 European cancer registries participating in the EUROCARE-4 collaborative study were used. A total of 183,683 multiple primary tumours were found, with an overall proportion of 6.3% over all the considered cancers, ranging from 0.4% (Naples, Italy) to 12.9% (Iceland). The proportion of multiple tumours varied greatly by type of tumour, being higher for those with high incidence and long survival (breast, prostate and colon-rectum). Five-year relative survival was lower when including patients with multiple cancers. For all cancers combined the average difference was -0.4 percentage points in women and -0.7 percentage points in men, and was greater for older registries. Inclusion of multiple tumours led to lower survival in 44 out of 45 cancer sites analysed, with the greatest differences found for larynx (-1.9%), oropharynx (-1.5%), and penis (-1.3%). Including multiple primary tumours in survival estimates for international comparison is advisable because it reduces the bias due to different observation periods, age, registration quality and completeness of registration. The general effect of inclusion is to reduce survival estimates by a variable amount depending on the proportion of multiple primaries and cancer site
