Curr Oncol 2021; 28:1706-1717. [PMID: 33946336 PMCID: PMC8161806 DOI: 10.3390/curroncol28030159] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2021] [Revised: 04/11/2021] [Accepted: 04/28/2021] [Indexed: 11/17/2022] Open
Abstract
(1) Background: Romania has one of the highest cervical cancer incidence rates in Europe. In Cluj County, the first screening program was initiated in 1998. We aimed to investigate the time trends of cervical cancer incidence in women from Cluj County and to evaluate the data quality at the Cancer Registry. (2) Methods: We calculated time trends of standardized incidence rates in the period 1998-2014 and the Annual Percent Change (APC%). To assess data quality, we used the indicators: mortality/incidence ratio (M/I), percentage of cases declared only at death (DOD%), and percentage of cases with pathological confirmation (PC%). (3) Results: The standardized incidence rate increased steadily, from 23.74 cases/100,000 in 1998, to 32/100,000 in 2014, with an APC% of 2.49% (p < 0.05). The rise in incidence affected both squamous cell carcinoma (APC% 2.49%) (p < 0.05) and cervical adenocarcinoma (APC% 10.54%) (p < 0.05). The M/I ratio was 0.29, DOD% 2.66%, and MC% 94.8%. The last two parameters are within the silver standard concerning data quality. (4) Conclusions. Our study revealed an ascending trend of cervical cancer incidence, more consistent for adenocarcinoma, in the context of a newly introduced screening program and partially due to the improvement of the quality of case reporting at the Cancer Registry from Cluj.

Abstract
BackgroundOlder people experience poorer outcomes from colon cancer. We examined if treatment for colon cancer was related to age and if inequalities changed over time.MethodsData from the UK population-based Northern and Yorkshire Cancer Registry on 31 910 incident colon cancers (ICD10 C18) diagnosed between 1999–2010 were obtained. Likelihood of receipt of: (1) cancer-directed surgery, (2) chemotherapy in surgical patients, (3) chemotherapy in non-surgical patients by age, adjusting for sex, area deprivation, cancer stage, comorbidity and period of diagnosis, was examined.ResultsAge-related inequalities in treatment exist after adjustment for confounding factors. Patients aged 60– 69, 70–79 and 80+ years were significantly less likely to receive surgery than those aged <60 years (multivariable ORs (95% CI) 0.84(0.74 to 0.95), 0.54(0.48 to 0.61) and 0.19(0.17 to 0.21), respectively). Age-related differences in receipt of surgery and adjuvant chemotherapy (but not chemotherapy in non-surgical patients) narrowed over time for the ’younger old’ (aged <80 years) but did not diminish for the oldest patients.ConclusionsAge inequality in treatment of colon cancer remains after adjustment for confounders, suggesting age remains a major factor in treatment decisions. Research is needed to better understand the cancer treatment decision-making process, and how to influence this, for older patients.

Abstract
Background The CONCORD study compares population-based relative survival from cancer using data from cancer registries in five continents. To estimate relative survival, general mortality life tables are required. Available statistics are incomplete, so various approaches are used to construct complete life tables. This article outlines how the life tables were constructed for CONCORD; it compares life expectancy at birth between 101 populations covered by cancer registries in 31 countries and compares the impact of two approaches to the deployment of life tables in relative survival analysis. Methods The CONCORD approach, using specific mathematical methods, produced complete (single-year-of-age) life tables by sex, cancer registry area, calendar year (1990–1999) and race (only in the USA). In order to study the impact of different approaches, we compared relative survival in the USA using the US national life table, centered on the relevant census years, and the CONCORD approach. We estimated relative survival in each American participating cancer registry for patients diagnosed with breast (women), colorectal or prostate cancer during 1990–1994 and followed up to 1999. Results Average life expectancy at birth during 1990–1999 varied in CONCORD cancer registry areas from 64 to 78 years in males and from 71 to 84 years in females. It increased during the 1990s more in men than in women. In the USA, it was lower in blacks than in whites. Relative survival in American populations was lower with the CONCORD approach, which incorporates trends and geographic variation in background mortality, than with the USA census life tables. Conclusions International variation in background mortality by geographic area, calendar time, race, age and sex is wide. We suggest that in international comparisons of cancer relative survival, complete life tables that are specific for cancer registry area, calendar year and race should be used.

Abstract
Aims: United States' (US) colorectal cancer (CRC) screening and treatment practices seek to reduce mortality. We examined the survival of US patients compared with patients in the virtually unscreened Norwegian population. Methods: We compared short-term survival after CRC between the US and Norway using relative survival (RS) and excess mortality (EMR) analyses. The CRC patients were aged 50 and older diagnosed in the US (Surveillance, Epidemiology and End Results registry, 2004, N=9511) and in Norway (Cancer Registry of Norway, 2003-2005, N=8256). Results: Death occurred within three years for 39% of the CRC patients. Stage distributions were more favorable for US patients. Stage-specific survival was similar for localized and regional cancers, but more favorable for US distant cancers. In multivariate models of patient, tumor and treatment characteristics, patients (especially below age 80) in the US experienced longer survival (EMR 0.9, CI 0.8-0.9). Stage-specific analyses showed, however, that survival for localized cancers was relatively shorter in the US than in Norway (EMR 1.4, CI 1.1-1.8), but longer for distant cancers (EMR 0.8, CI 0.7-0.8). Conclusions: The enhanced survival for US CRC patients likely reflects a screening-related earlier diagnostic stage distribution, as well as prioritized life extension for patients with metastatic cancers, reflecting vastly different health care systems in the two countries. CRC screening is currently under consideration in Norway. For survival outcomes, the current findings do not discourage such an implementation. Other screening-related aspects such as feasibility and cost-benefit are, however, also relevant and warrant further research within a socialized health system.

Abstract
The aim of this study was to determine the incidence trends of cutaneous melanoma (CM) and squamous cell carcinoma (SCC) in Cluj County, from 1998 to 2011, and the 5-year net survival between 2006 and 2010. Data on all cases of CM and SCC between 1998 and 2011 were obtained from Cluj Cancer Registry. Incidence rates were age standardized by the direct method Age Standardized Incidence Rate (ASIR), using the world standard population. Trends and annual percentage change (APC) of incidence rates were calculated by joinpoint regression analysis. The Pohar-Perme estimator was used to examine the 5-year net survival of cases diagnosed during 2006-2010 and followed up until December 2015. A total of 580 cases of CM and 397 cases of SCC were reported. During 1998-2011, the ASIR of CM increased significantly by 7.8% APC in male patients and by 7.42% APC in female patients, and the ASIR for SCC increased by 9.40% APC in male patients. In female patients, the incidence of SCC increased by 12.65% APC during 2002-2011. The 5-year net survival during 2006-2010 was 0.64 in men and 0.75 in women for CM and 0.86 and 1.00, respectively, for SCC. Survival rates showed an improving trend during 2006-2010, and were generally lower in men. Survival from both entities decreased with age and was lower in rural areas and in advanced stages in both sexes. This study reveals a rising incidence of cutaneous cancers in concordance with international trends. These data support the important role of primary and secondary prevention of skin cancers, focusing not only on melanoma, due to its lower survival, but also on SCC, in order to reduce their burden.

Abstract
OBJECTIVES This study examined to what extent the higher mortality in the United States compared to many European countries is explained by larger social disparities within the United States. We estimated the expected US mortality if educational disparities in the United States were similar to those in 7 European countries. METHODS Poisson models were used to quantify the association between education and mortality for men and women aged 30 to 74 years in the United States, Belgium, Denmark, Finland, France, Norway, Sweden, and Switzerland for the period 1989 to 2003. US data came from the National Health Interview Survey linked to the National Death Index and the European data came from censuses linked to national mortality registries. RESULTS If people in the United States had the same distribution of education as their European counterparts, the US mortality disadvantage would be larger. However, if educational disparities in mortality within the United States equaled those within Europe, mortality differences between the United States and Europe would be reduced by 20% to 100%. CONCLUSIONS Larger educational disparities in mortality in the United States than in Europe partly explain why US adults have higher mortality than their European counterparts. Policies to reduce mortality among the lower educated will be necessary to bridge the mortality gap between the United States and European countries.

Abstract
OBJECTIVES Prostate cancer mortality (PCM) in the USA is among the lowest in the world, whereas PCM in England is among the highest in Europe. This paper aims to assess the association of variation in use of definitive therapy on risk-adjusted PCM in England as compared with the USA. DESIGN Observational study. SETTING Cancer registry data from England and the USA. PARTICIPANTS Men diagnosed with non-metastatic prostate cancer (PCa) in England and the USA between 2004 and 2008. OUTCOME MEASURES Competing-risks survival analyses to estimate subhazard ratios (SHR) of PCM adjusted for age, ethnicity, year of diagnosis, Gleason score (GS) and clinical tumour (cT) stage. RESULTS 222,163 men were eligible for inclusion. Compared with American patients, English patients were more likely to present at an older age (70-79 years: England 44.2%, USA 29.3%, p<0.001), with higher tumour stage (cT3-T4: England 25.1%, USA 8.6%, p<0.001) and higher GS (GS 8-10: England 20.7%, USA 11.2%, p<0.001). They were also less likely to receive definitive therapy (England 38%, USA 77%, p<0.001). English patients were more likely to die of PCa (SHR=1.9, 95% CI 1.7 to 2.0, p<0.001). However, this difference was no longer statistically significant when also adjusted for use of definitive therapy (SHR=1.0, 95% CI 1.0 to 1.1, p=0.3). CONCLUSIONS Risk-adjusted PCM is significantly higher in England compared with the USA. This difference may be explained by less frequent use of definitive therapy in England.

Abstract
PURPOSE Over 5100 colorectal cancers (CRCs) are diagnosed in the United Kingdom in 85 years and older age group per year but little is known of cancer progression in this group. We assessed clinical, pathological and molecular features of CRC with early and late mortality in such patients. METHODS Data were analysed in relation to early mortality and long-term survival in 90 consecutive patients with CRC aged 85 years or older in a single hospital. RESULTS Patients not undergoing operation, those with an ASA score of III or greater and those with advanced tumour stage were more likely to die within 30 days. Regression analysis showed that 30 day mortality was independently related to failure to undergo resection (odds ratio (O.R.), 10.0; 95% confidence interval [C.I.], 1.7-58.2; p=0.01) and an ASA score of III or greater (O.R. 13.0; 95% C.I., 1.4-12.6; p=0.03). All cause three and five year survival were 47% and 23% respectively for patients who are alive 30 days after diagnosis. Three and five year relative survivals were 64% and 54%, respectively. Long-term outcome was independently related to tumour stage (relative risk [R.R.], 2; 95% C.I., 1.3-3.1; p=0.001), presence of co-morbid diseases (R.R., 2.8; 95% C.I., 1.3-6.0; p=0.007) and lipid peroxidation status (R.R., 2.9; 95% C.I., 1.1-7.5; p=0.025). CONCLUSIONS An active multidisciplinary approach to the care of patients with CRC at the upper extreme of life is reasonable. It also seems sensible to individualise care based upon the extent of disease at diagnosis and the presence of co-morbid conditions. Further studies to examine the role of lipid peroxidation are warranted.

Abstract
Americans lead shorter and less healthy lives than do people in other high-income countries. We review the evidence and explanations for these variations in longevity and health. Our overview suggests that the US health disadvantage applies to multiple mortality and morbidity outcomes. The American health disadvantage begins at birth and extends across the life course, and it is particularly marked for American women and for regions in the US South and Midwest. Proposed explanations include differences in health care, individual behaviors, socioeconomic inequalities, and the built physical environment. Although these factors may contribute to poorer health in America, a focus on proximal causes fails to adequately account for the ubiquity of the US health disadvantage across the life course. We discuss the role of specific public policies and conclude that while multiple causes are implicated, crucial differences in social policy might underlie an important part of the US health disadvantage.

Abstract
BACKGROUND AND OBJECTIVES In 2013 the first German S-3 guidelines on the diagnosis, treatment, and follow-up of melanoma were published in the framework of the German Guideline Program on Oncology. Quality indicators were developed at the same time as the guideline development process in order to implement the guideline recommendations. PATIENTS AND METHODS A multidisciplinary, interprofessional working group developed quality indicators following a standardized process. RESULTS Twelve quality indicators directly linked to guideline recommendations were generated and agreed on by consensus. They were integrated into the catalogue of requirements for dermato-oncological centers certified by the German Cancer Society. CONCLUSIONS The close cooperation between the guideline group and commission for certification allowed the guideline contents to be implemented in the form of quality indicators in everyday clinical practice. Adherence to the guidelines is required and continuously evaluated as part of certification.

Abstract
The International Cancer Benchmarking Partnership (ICBP) was initiated by the Department of Health in England to study international variation in cancer survival, and to inform policy to improve cancer survival. It is a research collaboration between twelve jurisdictions in six countries: Australia (New South Wales, Victoria), Canada (Alberta, British Columbia, Manitoba, Ontario), Denmark, Norway, Sweden, and the United Kingdom (England, Northern Ireland, Wales). Leadership is provided by policymakers, with academics, clinicians and cancer registries forming an international network to conduct the research. The project currently has five modules examining: (1) cancer survival, (2) population awareness and beliefs about cancer, (3) attitudes, behaviours and systems in primary care, (4) delays in diagnosis and treatment, and their causes, and (5) treatment, co-morbidities and other factors. These modules employ a range of methodologies including epidemiological and statistical analyses, surveys and clinical record audit. The first publications have already been used to inform and develop cancer policies in participating countries, and a further series of publications is under way. The module design, governance structure, funding arrangements and management approach to the partnership provide a case study in conducting international comparisons of health systems that are both academically and clinically robust and of immediate relevance to policymakers.

Abstract
Serious concern arose in the scientific literature about the state of and progress in cancer survival among adolescent and young adult (AYA) patients in the recent years. We provide an up-to-date international comparison of survival among AYA patients. Using population-based cancer data from 11 German cancer registries and the SEER Program of the United States (covering populations of 39 and 33 million people, respectively), standardized tumor group classifications, period analysis and modeling, we compared the 5-year relative survival of AYA patients in the age groups 15-29 and 30-39 to survival seen among adults aged 40-49 for the 2002-2006 period. Additionally, we also provide an age-specific survival comparison between the two countries. In 2002-2006, for the overwhelming majority of the more than 30 types of cancer examined, AYA patients aged both 15-29 and 30-39 years had higher or similar survival than patients in the age group 40-49 in both countries. A numerically large and statistically significant survival deficit among AYA patients was only found for breast carcinomas in both populations, and colorectal and stomach carcinoma in the United States for the age group 15-29. Overall, results of the country-specific comparisons did not indicate systematic differences. With very few exceptions, no survival deficit between AYA patients and adults aged 40-49 years was found in either of the examined countries in the first decade of the 21st century.

Abstract
Little is known about patients with malignant digestive neuroendocrine tumours (MD-NETs). Although their incidence is increasing, MD-NETs remain a rare cancer, representing 1% of digestive cancers. Most MD-NETs are well-differentiated. MD-NET poorly differentiated carcinomas account for 20% of cases on average. Anatomical localisation of MD-NETs varied according to geographic region. Stage at diagnosis and prognosis for patients with MD-NETs in the general population are considerably worse than often reported from small hospital case series. Prognosis varies with tumour differentiation, anatomic site and histological subtype. There are significant differences in survival from MD-NETs among European countries, independent of other prognostic factors. Early diagnosis is difficult; new therapeutic options appear to represent the best approach to improving prognosis.

Abstract
BACKGROUND Time trends comparisons by age are important to understand the specific needs of elderly cancer patients and to improve clinical procedures. The aim is to compare 1998-2005 cancer incidence and mortality trends in Italy and the US for both sexes and for two age groups, namely 50-69 year old and 70+ year old. METHODS Cancer incidence and mortality data came from 22 Cancer Registries (CRs) of the Italian association of cancer registries (AIRTUM), while the US incidence records were provided by 13 SEER CRs and the mortality statistics provided by the WHO Database. Trends were analysed by the Joinpoint Regression Program in order to obtain Annual Percent Changes and Joinpoints. RESULTS Colorectal cancer incidence trends were favourable in the US for both sexes and in both age groups, whilst the rates increased in Italian elderly individuals and mortality rates fell markedly only in the US. For lung cancer, incidence and mortality decreased in men but increased in women in the two geographical areas. Breast cancer incidence and mortality declined both in Italy and the US for younger women, but the trends were less favourable in the Italian elderly individuals. The increase of prostate incidence slowed down and mortality diminished for every age group in the US, whilst in Italy only in the younger group. CONCLUSIONS For major cancers, the Italian elderly experienced less favourable trends than the middle-aged patients whereas, in the US, the trends were similar for both age groups and favourable also for the elderly.

Abstract
Breast cancer survival is reportedly higher in the US than in Europe. The first worldwide study (CONCORD) found wide international differences in age-standardized survival. The aim of this study is to explain these survival differences. Population-based data on stage at diagnosis, diagnostic procedures, treatment and follow-up were collected for about 20,000 women diagnosed with breast cancer aged 15-99 years during 1996-98 in 7 US states and 12 European countries. Age-standardized net survival and the excess hazard of death up to 5 years after diagnosis were estimated by jurisdiction (registry, country, European region), age and stage with flexible parametric models. Breast cancers were generally less advanced in the US than in Europe. Stage also varied less between US states than between European jurisdictions. Early, node-negative tumors were more frequent in the US (39%) than in Europe (32%), while locally advanced tumors were twice as frequent in Europe (8%), and metastatic tumors of similar frequency (5-6%). Net survival in Northern, Western and Southern Europe (81-84%) was similar to that in the US (84%), but lower in Eastern Europe (69%). For the first 3 years after diagnosis the mean excess hazard was higher in Eastern Europe than elsewhere: the difference was most marked for women aged 70-99 years, and mainly confined to women with locally advanced or metastatic tumors. Differences in breast cancer survival between Europe and the US in the late 1990s were mainly explained by lower survival in Eastern Europe, where low healthcare expenditure may have constrained the quality of treatment.

Abstract
As the USA expands health insurance coverage, comparing utilization of healthcare services with countries like Taiwan that already have universal coverage can highlight problematic areas of each system. The universal coverage plan of Taiwan is the newest among developed countries, and it is known for readily providing access to care at low costs. However, Taiwan experiences problems on the supply side, such as inadequate compensation for providers, especially in the area of preventive care. We compare the use of preventive, hospital, and emergency care between the USA and Taiwan. The rate of preventive care use is much higher in the USA than in Taiwan, whereas the use of hospital and emergency care is about the same. Results of our decomposition analysis suggest that higher levels of education and income, along with inferior health status in the USA, are significant factors, each explaining between 7% and 15% of the gap in preventive care use. Our analysis suggests that, in addition to universal coverage, proper remuneration schemes, education levels, and cultural attitudes towards health care are important factors that influence the use of preventive care.

Abstract
The National Institute for Clinical Excellence (NICE) defined the process of care for haematological malignancies in Improving outcomes in haematological cancers. The manual in 2003. The most challenging recommendation has been the requirement to develop integrated laboratory services for accurate diagnosis. This is an aim that has not been fully achieved. The unified concept of haematological malignancy is recent and based on an understanding of the cellular pathology of the bone marrow and immune systems. Historical UK pathology practice has previously resulted in the separation of laboratory haematology from histopathology and of liquid and tissue specimens. Proposals for reintegration and centralization with specialist-led, centralized diagnostic and reporting services challenge the fragmented historical model. Accuracy and certainty of diagnosis remains problematic, particularly for lymphomas, with evidence that the accuracy of diagnosis is slowly improving but still only approaches 85%. There is a potentially significant human and financial cost of diagnostic errors. No nationwide, validated and comparable epidemiology/population-based data exist for accurate and complete ascertainment of new cases of haematological cancer, service planning or clinical outcomes monitoring. This article examines the original rationale behind the NICE guidance and outlines the key components and processes of an integrated diagnostic service.

Abstract
BACKGROUND The United States health care debate has focused on the nation's uniquely high rates of lack of insurance and poor health outcomes relative to other high-income countries. Large disparities in health outcomes are well-documented in the US, but the most recent assessment of county disparities in mortality is from 1999. It is critical to tracking progress of health reform legislation to have an up-to-date assessment of disparities in life expectancy across counties. US disparities can be seen more clearly in the context of how progress in each county compares to international trends. METHODS We use newly released mortality data by age, sex, and county for the US from 2000 to 2007 to compute life tables separately for each sex, for all races combined, for whites, and for blacks. We propose, validate, and apply novel methods to estimate recent life tables for small areas to generate up-to-date estimates. Life expectancy rates and changes in life expectancy for counties are compared to the life expectancies across nations in 2000 and 2007. We calculate the number of calendar years behind each county is in 2000 and 2007 compared to an international life expectancy time series. RESULTS Across US counties, life expectancy in 2007 ranged from 65.9 to 81.1 years for men and 73.5 to 86.0 years for women. When compared against a time series of life expectancy in the 10 nations with the lowest mortality, US counties range from being 15 calendar years ahead to over 50 calendar years behind for men and 16 calendar years ahead to over 50 calendar years behind for women. County life expectancy for black men ranges from 59.4 to 77.2 years, with counties ranging from seven to over 50 calendar years behind the international frontier; for black women, the range is 69.6 to 82.6 years, with counties ranging from eight to over 50 calendar years behind. Between 2000 and 2007, 80% (men) and 91% (women) of American counties fell in standing against this international life expectancy standard. CONCLUSIONS The US has extremely large geographic and racial disparities, with some communities having life expectancies already well behind those of the best-performing nations. At the same time, relative performance for most communities continues to drop. Efforts to address these issues will need to tackle the leading preventable causes of death.

Abstract
BACKGROUND Stomach cancer is the most common cancer among Iranian men. We studied survival rates and prognostic factors of stomach cancer in a referral hospital in Tehran, Iran. PATIENTS AND METHODS We followed 367 stomach cancer patients hospitalized between 1991 and 2007 in the Baqyiatallah Hospital. We estimated survival rates overall and among operable patients exclusively. Hazard ratios (HR) for the different prognostic factors were estimated with the Cox regression model. Furthermore, we studied international variations in stage distribution and 5 year survival for stomach cancer. RESULTS Overall, 5 year survival of stomach cancer was low (14%), and the majority of patients (53%) were diagnosed at stage IV. Stage, tumor size, age, and gender were statistically significant prognostic factors. Relative risk of mortality in stage IV compared to stage IA was 9.9 (95% confidence interval 5.8-16.9). The highest 5 year survival was reported from Japan, particularly among screening detected patients (89.4%). Among operable patients, 5 year survival was 32.6% in France, 26% in the USA, and 30.5% in China, which was close to the rates estimated in our study (24%). CONCLUSIONS Due to stomach cancer being frequently diagnosed in advanced stages, its prognosis is poor in Iran. Early diagnosis and downstaging strategies need to be prioritized to improve the prognosis of stomach cancer.

Abstract
Vital statistics for the lymphoid malignancies obtained from the Surveillance, Epidemiology and End Results (SEER) Program have seldom been directly compared to data from alternative national databases. While SEER is recognized as the standard, some lymphoid malignancies-especially the chronic ones--may be underreported. We compared the incidence, all-cause and cause-specific mortality for Hodgkin's lymphoma (HL), non-Hodgkin's lymphoma (NHL), multiple myeloma (MM) and chronic lymphocytic leukaemia (CLL) in SEER to that in the Nurses' Health Study (NHS), a national cohort study of 121,700 female registered nurses, matching for age and race. In over 2.5 million person-years, the incidence of HL was the same as in SEER (SIR=1.01 [0.75, 1.26]), while the incidence of NHL, CLL and MM were slightly higher. All-cause mortality was lower for the lymphoid malignancies except for MM, which was the same; there were no differences in cause-specific mortality, except for MM (HR=1.26 [1.07, 1.48]). Our analysis suggests that, at least among white women, SEER is a reliable data source with respect to lymphoid malignancies.

Abstract
Cancer mortality in elderly people is described to highlight the mechanisms that could potentially explain observed differences with other age groups. Data from 15 French cancer registries were considered in the search for the 5-year outcome of patients diagnosed during the period 1989-1997. Relative survival, excess mortality hazard, and hazard ratio of mortality were estimated to describe patient outcome according to age. Five cancer sites were selected: colon/rectum, prostate, breast, head/neck, and lung. An excess mortality rate was found in patients aged over 75 at the time of diagnosis. This excess mortality rate was mainly seen during the first months after diagnosis, then it decreased gradually with time. An initial phenomenon of patient selection, a greater disease severity at the time of diagnosis, and less-effective treatments given to elderly patients are the most plausible explanations for the increased risk of cancer-related death in the eldest patients.

Abstract
Despite the historic significance of the healthcare reform bill that was passed into law by President Obama in March 2010, the debate still rages. The UK National Health Service (NHS) has featured prominently in the current American debate on healthcare reform, with critics calling attention to its perceived shortcomings. Some of these, such as the existence of 'death panels', can easily be dismissed, but others, such as the cancer survival deficit, cannot. This paper reviews the evidence on outcomes from cancer and other chronic non-communicable diseases, the two leading causes of death in both countries. The headline figures showing better cancer survival in the USA are exaggerated by methodological issues, but a gap remains, due in large part to better outcomes among older people. Outcomes among younger people with chronic disease are, however, much worse in the USA. Paradoxically, given the nature of the debate in the USA so far, those parts of the US health system that get the best results, such as the Veterans' Administration, or the elderly on Medicare, are those that most closely resemble the British NHS - but which are funded somewhat more generously.

Abstract
Compared to other developed countries, the United States ranks poorly in terms of life expectancy at age 50. We seek to shed light on the US's low life expectancy ranking by comparing the age-specific death rates of 18 developed countries at older ages. A striking pattern emerges: between ages 40 and 75, US all-cause mortality rates are among the poorest in the set of comparison countries. The US position improves dramatically after age 75 for both males and females. We consider four possible explanations of the age patterns revealed by this analysis: (1) access to health insurance; (2) international differences in patterns of smoking; (3) age patterns of health care system performance; and (4) selection processes. We find that health insurance and smoking are not plausible sources of this age pattern. While we cannot rule out selection, we present suggestive evidence that an unusually vigorous deployment of life-saving technologies by the US health care system at very old ages is contributing to the age-pattern of US mortality rankings. Differences in obesity distributions are likely to be making a moderate contribution to the pattern but uncertainty about the risks associated with obesity prevents a precise assessment.

Abstract
OBJECTIVE To analyze the characteristics of patients with lung cancer. METHODS A retrospective descriptive study of patients receiving a histopathological diagnosis of lung cancer between 1995 and 2002 in the city of Manaus, Brazil. Data were collected from the medical archives of three hospitals. Statistical analyses were carried out, and survival curves were generated by means of an actuarial estimator. RESULTS Of the 352 patients selected, 262 (74.4%) were male and 90 (25.6%) were female. The mean age was 62 years. The following histological types were identified: squamous cell carcinoma, 62.8%; adenocarcinoma, 24.7%; small cell carcinoma, 9.1%; and large cell carcinoma, 3.4%. The most common stages were stages IIIB and IV, in 45% and 21.5%, respectively. Of the total sample, 73.4% were submitted to treatment. Of these, 51.4% underwent radiotherapy; 16.6%, surgery; 15.8%, chemotherapy; and 16.2%, radiotherapy in association with chemotherapy. Cumulative survival rates were low: three-year survival was 6.5%, and five-year survival was 3.5%. CONCLUSIONS In this group of patients with lung cancer, survival rates were considerably lower than those reported in the literature. This might be attributable to the limited access to the specialized health care system and the advanced stage of the disease at diagnosis.

Abstract
Despite a major decline in incidence and mortality over several decades, stomach cancer is still the fourth most common cancer and the second most common cause of cancer death in the world. There is a 10-fold variation in incidence between populations at the highest and lowest risk. The incidence is particularly high in East Asia, Eastern Europe, and parts of Central and South America, and it is about twice as high among men than among women. Prognosis is generally rather poor, with 5-year relative survival below 30% in most countries. The best established risk factors for stomach cancer are Helicobacter pylori infection, the by far strongest established risk factor for distal stomach cancer, and male sex, a family history of stomach cancer, and smoking. While some factors related to diet and food preservation, such as high intake of salt-preserved foods and dietary nitrite or low intake of fruit and vegetables, are likely to increase the risk of stomach cancer, the quantitative impact of many dietary factors remains uncertain, partly due to limitations of exposure assessment and control for confounding factors. Future epidemiologic research should pay particular attention to differentiation of stomach cancer epidemiology by subsite, and to exploration of potential interactions between H. pylori infection, genetic, and environmental factors.

Quaglia A, Tavilla A, Shack L, Brenner H, Janssen-Heijnen M, Allemani C, Colonna M, Grande E, Grosclaude P, Vercelli M. The cancer survival gap between elderly and middle-aged patients in Europe is widening. Eur J Cancer 2008; 45:1006-16. [PMID: 19121578 DOI: 10.1016/j.ejca.2008.11.028] [Citation(s) in RCA: 151] [Impact Index Per Article: 9.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2008] [Revised: 09/25/2008] [Accepted: 11/04/2008] [Indexed: 02/06/2023]
Abstract
The present study is aimed to compare survival and prognostic changes over time between elderly (70-84 years) and middle-aged cancer patients (55-69 years). We considered seven cancer sites (stomach, colon, breast, cervix and corpus uteri, ovary and prostate) and all cancers combined (but excluding prostate and non-melanoma skin cancers). Five-year relative survival was estimated for cohorts of patients diagnosed in 1988-1999 in a pool of 51 European populations covered by cancer registries. Furthermore, we applied the period-analysis method to more recent incidence data from 32 cancer registries to provide 1- and 5-year relative survival estimates for the period of follow-up 2000-2002. A significant survival improvement was observed from 1988 to 1999 for all cancers combined and for every cancer site, except cervical cancer. However, survival increased at a slower rate in the elderly, so that the gap between younger and older patients widened, particularly for prostate cancer in men and for all considered cancers except cervical cancer in women. For breast and prostate cancers, the increasing gap was likely attributable to a larger use of, respectively, mammographic screening and PSA test in middle-aged with respect to the elderly. In the period analysis of the most recent data, relative survival was much higher in middle-aged patients than in the elderly. The differences were higher for breast and gynaecological cancers, and for prostate cancer. Most of this age gap was due to a very large difference in survival after the 1st year following the diagnosis. Differences were much smaller for conditional 5-year relative survival among patients who had already survived the first year. The increase of survival in elderly men is encouraging but the lesser improvement in women and, in particular, the widening gap for breast cancer suggest that many barriers still delay access to care and that enhanced prevention and clinical management remain major issues.

Abstract
Abstract
Background
Recognition of people presenting to the general practitioner with symptoms suggestive of colorectal cancer varies considerably, as do the subsequent patterns of referral and treatment. The Lower Gastrointestinal Electronic Referral Protocol (e-RP) was developed to be used alongside the national Choose and Book programme. This paper addresses the validation of the e-RP.
Methods
The e-RP was validated using three datasets: 100 consecutive patients with colorectal cancer, 100 2-week wait (TWW) suspected cancer referrals and 100 routine referrals. The actual destination of referred patients, their clinical diagnosis and referral urgency were compared with destination and referral urgency assigned by the e-RP.
Results
Some 43·0 per cent of patients with colorectal cancer were actually referred through the TWW system and the e-RP successfully upgraded 85·0 per cent of these patients as TWW referrals (Pearson χ2 = 9·76, 1 d.f., P = 0·002). The e-RP also redirected three of four patients with colorectal cancer in routine referrals to TWW clinics. Right-sided cancers were appropriately directed to colonoscopy as the first contact in secondary care or to outpatients for investigation of a palpable mass. Most patients with left-sided cancers were directed to flexible sigmoidoscopy clinics.
Conclusion
A dedicated referral protocol addressing all colorectal symptoms would significantly improve the overall yield of colorectal cancers through the TWW route and reduce delays in patient pathways with ‘straight to test’ in secondary care.

Abstract
Transatlantic cancer survival comparisons are scarce and involve mostly aggregate European data from the late 1980s. We compare the levels of cancer patient survival achieved in Germany and the United States (US) by the beginning of the 21st century, using data from the Cancer Registry of Saarland/Germany and the SEER Program of the US. Age-adjusted 5- and 10-year relative survival for 23 common forms of cancer derived by period analysis for the 2000-2002 period were calculated, with additional detailed age- and stage-specific analyses for cancers with the highest incidence. Among the 23 cancer sites, 5 (10) year relative survival was significantly higher for 1 (2) and 8 (5) cancers in Germany and the US, respectively. In Germany, survival was significantly higher for patients with stomach cancer, whereas survival was higher in the US for patients with breast, cervical, prostate, colorectal and oral cavity cancer. Among the most common cancers, age-specific survival differences were particularly pronounced for older patients with breast, colorectal and prostate cancer. Survival advantages of breast cancer patients in the US were mainly due to more favorable stage distributions. This comprehensive survival comparison between Germany and the US suggests that although survival was similar for the majority of the compared cancer sites, long-term prognosis of patients continues to be better in the US for many of the most common forms of cancer. Among these, differences between patients with breast and prostate cancer are probably due to more intensive screening activities.

Abstract
OBJECTIVES There is large geographic variation in incidence levels and time trends of hepatocellular carcinoma. We compared population-based liver cancer incidence and survival in European and U.S. populations in order to elucidate geographic differences and time trends for these variables. METHODS Since comparisons based on cancer registry data are problematic because of variations in liver cancer definition and coding, we considered a subset of cases likely to be mainly hepatocellular carcinoma, suitable for international comparison. Incidence and 5-yr relative survival were calculated from cases diagnosed in five European regions (30,423 cases) and the United States (6,976 cases) in 1982-1994. RESULTS Age-standardized incidence was highest in southern Europe (12/100,000 in men and 3/100,000 in women in 1992-94) and lowest in northern Europe, where incidence was similar to that of the United States (3/100,000 in men, <1/100,000 in women). Over the study period, incidence remained stable in the United States and most of Europe, except for a notable increase in southern Europe. Five-year relative survival was <10% in Europe, ranging from 8% (southern Europe) to 5% (eastern Europe), and 6% in the United States. Survival increased slightly with time, mainly in southern Europe and was unaffected by sex, but was better in younger patients. CONCLUSIONS Increasing incidence in southern Europe is probably related to hepatitis B and C infection and increasing alcohol intake, while improving survival may be due to greater surveillance for cirrhosis. The survival gap between clinical and population-based series suggests management is better in centers of excellence.

Abstract
AIM This paper is a report of a study to explore patients' experiences of having chemotherapy in a day hospital. BACKGROUND The nature of cancer care has changed dramatically in recent years with most patients receiving chemotherapy in a day hospital. Despite recognition of the need to explore patients' experience of cancer treatment, little research has been undertaken in this specific area. METHOD A qualitative approach was adopted with a convenience sample of 30 patients diagnosed with cancer and receiving chemotherapy in a day hospital. Data were collected from January 2002 to March 2003 using unstructured tape-recorded interviews and analysed using a narrative framework. FINDINGS Participants viewed their experiences of chemotherapy treatment from the initial perspective of having to face their need to have chemotherapy. Their experiences in the day hospital had both positive and negative dimensions. Positive aspects related to maintaining a sense of normality and absence of the sick role, whilst negative aspects were related to the dehumanizing, factory-like system in the day hospital. Organizational issues also influenced experiences, including the sense of comradeship with other patients. Participants indicated the need to remain positive about the future and to learn to 'work around' the treatment. CONCLUSION More effective methods are needed to develop patients' confidence and motivation to realize their self-care potential, together with increased awareness of organizational influences on patient experiences. Nurses need to focus on the 'here and now' concerns of patients as opposed to a biomedical perspective relating to treatment regimes, survival and prognosis.

Abstract
BACKGROUND The ageing of populations makes outcome monitoring among elderly cancer patients particularly important. PATIENTS AND METHODS Using data from the population-based Cancer Registry of Saarland, we examined age-specific trends in 5-year relative survival from 1979 to 2003 for patients with 15 common cancers in Germany. Model-based period analysis was applied to estimate 5-year relative survival for four age groups (15-54, 55-64, 65-74, 75+) in the periods 1979-1983, 1984-1988, 1989-1993, 1994-1998, and 1999-2003. RESULTS Overall, 5-year relative survival improved steadily from 42.2% in 1979-1983 to 56.7% in 1999-2003. From the youngest to the oldest age group, 5-year relative survival increased by 14.5, 12.1, 12.5, and 8.4 percent units, respectively, after adjusting for changes in the spectrum of cancer sites, and survival significantly improved for 10, 12, 11, and 5 cancer sites, respectively. The age gradient particularly increased for cancer sites with major progress in chemotherapeutic treatment regimens, such as ovarian cancer, non-Hodgkin's lymphoma and leukemia. CONCLUSIONS Relative survival of cancer patients increased considerably for many forms of cancer in Germany from 1979 to 2003. Increases were much less pronounced among elderly patients, leading to an increasing age gradient in prognosis.

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.

Abstract
PURPOSE To analyse survival from uveal melanoma diagnosed in England and Wales between 1986-1999 and followed up to 2001. METHODS Data from the National Cancer Registry at the Office for National Statistics were analysed. The data were compiled from population-based cancer registries covering all of England and Wales for all adults (aged 15-99) diagnosed with primary ocular malignancy, excluding eyelid tumours. Level of poverty was based on the national classification of area of residence at time of diagnosis. Regression models explored the influence of sex, age, and level of poverty on relative survival for patients diagnosed with uveal melanoma during successive calendar periods. RESULTS Of 5,519 adults identified with primary ocular malignancy, 4,717 had melanoma, of which 4,308 (91%) were eligible for analysis. Two-thirds (67%) of the ocular melanomas were uveal, 5% conjunctival, and 2% orbital; the subsite was unspecified in 26%. Relative survival from uveal melanoma was 95% at 1 year and 72% at 5 years. There was no statistically significant variation in 1-year or 5-year survival by sex or poverty level and no significant trend over time. Older patients had significantly worse survival (p < 0.001). CONCLUSIONS This study provides national population-based survival estimates for England and Wales for uveal melanoma, the most common primary intraocular malignancy in adults. Five-year relative survival, an important indicator of the quality of cancer care, has not improved since the 1980s. Greater age, but not gender or level of poverty, is associated with a poorer prognosis. A standardised classification of uveal melanoma is required to improve reporting to cancer registries. Further research is required to explore reasons for lower relative survival in older persons.

Abstract
BACKGROUND AND AIMS Colorectal cancer is a major cause of cancer death in European countries and differences in screening implementation may in part explain USA vs European survival differences. Despite the evidence, no study has evaluated the population colorectal cancer screening (CCS) coverage in any European country. We aimed to index the current CCS practices among a large sample of Greek healthy adults. MATERIALS AND METHODS The study was designed as a cross-sectional survey. Screening practice habits of 5,259 healthy adults, aged 50-80, were surveyed. Both overall and screening practices of stool occult blood test (SOBT), digital rectal examination (DRE), and colonoscopy or sigmoidoscopy (COL/SIG) were analyzed. RESULTS Of the population analyzed, 90.1% declared that they were interested in cancer prevention activities. Overall SOBT practice rate within the last 2 years was 4.77%. When only screening procedures were analyzed, this percentage shrank to 1.73%. Overall and screening COL/SIG rates within the last 10 years were 8.76 and 1.74%, respectively. The respective proportions of individuals who underwent DRE were 14.54 and 5.2%. Evidence-based screening practices were influenced by age, family history of colorectal cancer, profession, and educational level; however, SOBT and colonoscopy/sigmoidoscopy did not overcome 4.1 and 4.6% in any subpopulation analyzed. CONCLUSION The level of CCS coverage among the examined sample of Greek adults was discouraging. Surveys among other European countries are encouraged.

Abstract
BACKGROUND AND AIMS Little is known about the prognosis of patients with malignant digestive endocrine tumors (MDETs), primarily because of their rarity. METHODS Survival from these tumors has been evaluated in a large, well-defined, national population. All patients diagnosed and registered in England and Wales during the 14-year period from 1986 to 1999 were followed up for vital status to the end of 2001. Relative survival was estimated and the impact of age, sex, period, histology, and anatomic site modeled. RESULTS Among 4104 cases of MDETs, 21.2% were small cell tumors. Relative survival for all MDETs combined was 45.9% at 5 years and 38.4% at 10 years. Five-year survival was 56.8% for well-differentiated tumors but only 5.2% for small cell tumors (P < .0001). Survival was highest for large bowel tumors and lowest for esophageal tumors. Among well-differentiated pancreatic tumors, 5-year relative survival was 49.2% for insulinomas, 39.9% for gastrinomas, 17.1% for glucagonomas, 26.3% for carcinoid tumors, and 29.3% for nonfunctioning tumors. There was no difference in survival between socioeconomic groups. Five-year survival did not improve between 1986 and 2001. Survival was higher for women and for younger patients. Gender, age at diagnosis, and anatomic site were independent prognostic factors. CONCLUSIONS The prognosis of patients with MDETs in the general population is considerably worse than is often reported from small hospital case series. Prognosis varies with tumor differentiation, anatomic site, and histologic type. Early diagnosis is difficult; new therapeutic options appear to represent the best approach to improved prognosis.

Abstract
BACKGROUND Geographical inequalities in lung cancer treatment and patient survival have been described. We hypothesized that lung cancer patients' access to treatment may be influenced by deprivation and the pathway to care. METHODS Case notes were reviewed for patients resident in south-east London who were registered with lung cancer at the Thames Cancer Registry in 1998. Use of surgery, chemotherapy, radiotherapy or any specific treatment and one-year survival were examined. Analyses were adjusted for age, sex, histology, stage and basis of diagnosis. RESULTS Data for 695 out of 958 (73%) patients were analysed. Subjects who were initially referred to a specialist in thoracic medicine, surgery or oncology were more likely to receive active treatment (71%) than subjects who were referred to other consultants (51%) or who were admitted as emergencies (42%) (P < 0.0001). CONCLUSION Socio-economic deprivation was associated with lower rates of treatment and this partly explained variations in survival. Subjects who were referred to specialists were more likely to receive active treatment and treatment patterns varied between first trust attended.

Abstract
OBJECTIVES Increasing survival rates of cervical cancer (CC) patients and the trend towards more toxic multimodal therapy have led to focus on the quality of life (QOL) of cervical cancer survivors (CCSs). The aim of this critical review was to summarize and discuss the research findings of QOL in CCSs based on self-report measures in terms of physical, psychosocial, and sexual well-being. METHODS Electronic databases were used to identify studies published between 1966 and August 2005. A quality assessment using methodological and treatment-related criteria was performed to distinguish between studies with good and less good methodology. RESULTS Twenty-three studies were included, whereof eight had a good methodology. Eight studies used at least one questionnaire that had not been validated previously, and only one of the validated questionnaires had been tested in former studies of CCSs. The studies with good methodology focused primarily on sexual and social function after treatment, and less on physical and psychological well-being. The trend is that radiotherapy is more associated with reduced QOL dimensions than surgery or chemotherapy. In earlier stages of CC and following surgery alone, there seem to be minor differences between CCSs and control groups concerning various QOL domains. CONCLUSIONS Reviewed studies indicate that quality of life in cervical cancer survivors is reduced compared to the general female population following radiotherapy, but less so following surgery and earlier stages of cervical cancer. Shortcomings of both methodology and content of the studies reviewed preclude definite conclusions concerning QOL for the moment.

BACKGROUND Mortality rates from lung cancer are known to vary considerably between countries. Differences in patients, disease, investigation and treatment are thought to account for some survival shortfalls but it is not known whether differences in collection or processing of data also contribute. METHODOLOGY We searched recognised sources where information regarding mortality rates have been published for the United Kingdom, Europe and United States (US). Data regarding patient selection, demographics and mortality rates were extracted. RESULTS Published international 5-year survival for patients with lung cancer varies from 5% to 16%. The survival figures quoted in the literature are based on data which varies widely in its collection and statistical analysis and this information is not always in the public domain. Data from the US suggests an overall 5-year survival rate of up to 16% although this figure covers only a quarter of the general population and excludes patients without histological confirmation. Many European countries report higher mortality rates although in most, data includes patients without proven histology. European datasets have variable population coverage. CONCLUSION Selective data collection and variable population coverage may account for some of the differences in lung cancer survival between countries. More transparent description of data collection and analysis would be helpful but ideally a uniform method of reporting data is required in order to make valid comparisons in mortality rates.
