Survival differences between European and US patients with colorectal cancer: role of stage at diagnosis and surgery
2005
Background: Population based colorectal cancer survival among patients diagnosed in 1985–89 was lower in Europe than in the USA (45% v 59% five year relative survival). Aims: To explain this difference in survival using a new analytic approach for patients diagnosed between 1990 and 1991. Subjects: A total of 2492 European and 11 191 US colorectal adenocarcinoma patients registered by 10 European and nine US cancer registries. Methods: We obtained clinical information on disease stage, number of lymph nodes examined, and surgical treatment. We analysed three year relative survival, calculating relative excess risks of death (RERs, referent category US patients) adjusted for age, sex, site, …
Survival of stomach and esophagus cancer patients in Germany in the early 21st century
2012
Esophagus and stomach cancers are associated with poor prognosis. But most published population-based cancer survival estimates for stomach and esophagus cancer refer to survival experience of patients diagnosed in the 1990s or earlier years. The aim of this study was to provide up-to-date survival estimates and trends for patients with stomach and esophagus cancer in Germany.Our analysis is based on data from 11 population-based cancer registries, covering 33 million inhabitants. Patients diagnosed with stomach and esophagus cancer in 1997-2006 were included. Period analysis was used to derive five-year relative survival estimates and trends by age, sex, cancer subsite, and stage for the t…
Recent Trends in Survival of Patients With Pancreatic Cancer in Germany and the United States
2016
Objectives Survival improvement for pancreatic cancer has not been observed in the last 4 decades. We report the most up-to-date population-based relative survival (RS) estimates and recent trends in Germany and the United States. Methods Data for patients diagnosed in 1997 to 2010 and followed up to 2010 were drawn from 12 population-based German cancer registries and the US SEER (Surveillance, Epidemiology and End Results) 13 registries database. Using period analysis, 5-year RS for 2007 to 2010 was derived. Model-based period analysis was used to assess 5-year RS time trends, 2002-2010. Results In total 28,977 (Germany) and 34,793 (United States) patients aged 15 to 74 years were analyze…
Improved population level survival in younger Hodgkin lymphoma patients in Germany in the early 21st century.
2013
Summary Treatment for Hodgkin lymphoma (HL) is more aggressive in Germany than in the United States (US) and differences in treatment may lead to differences in population level survival. Patients diagnosed with HL in 11 German states in 1997–2006 were included in the analyses and were compared to similar analyses from patients in the Surveillance, Epidemiology, and End Results database in the US. Period analysis was used to calculate 5-year relative survival for the time period of 2002–2006 overall and by gender, age and histology. Overall 5-year relative survival for patients with HL in Germany was 84·3%, compared to 80·6% for the US. Survival was highest in patients aged 15–29 years at 9…
Population-based study of ovarian cancer in Côte d'Or: prognostic factors and trends in relative survival rates over the last 20 years
2010
Abstract Background The aim of this population-based study was to assess independent prognostic factors in ovarian cancer using relative survival (RS) and to investigate changes in RS rates from 1982 to 2005. Methods Data on 748 patients with ovarian cancer were provided by the Côte d'Or gynaecologic cancer registry. The RS was estimated using a generalized linear model with a Poisson error structure. Relative survival and its 95% confidence interval (CI) were described at the following specific time points 1, 3 and 5 years. The effect of prognostic factors on survival was assessed with multivariate analyses of RS. Results The median follow-up was 12 years. The RS rates at 1, 3 and 5 years …
Survival of cervical cancer patients in Germany in the early 21st century: A period analysis by age, histology, and stage
2012
Background: Population-based studies on endometrial cancer providing survival estimates by age, histology, and stage have been sparse. We aimed to derive most up-to-date and detailed survival estimates for endometrial cancer patients in Germany. Methods: We used a pooled German national dataset including data from 11 cancer registries covering a population of 33 million people. 30,906 patients diagnosed with endometrial cancer in 1997-2006 were included. Period analysis was performed to calculate 5-year relative survival (RS) in 2002-2006. Trends in survival between 2002 and 2006 were examined using model-based period analysis. Age-adjustment was performed using five age groups (15-44, 45-5…
Age and case mix-standardised survival for all cancer patients in Europe 1999-2007: Results of EUROCARE-5, a population-based study
2015
Background: Overall survival after cancer is frequently used when assessing a health care service’s performance as a whole. It is mainly used by the public, politicians and the media, and is often dismissed by clinicians because of the heterogeneous mix of different cancers, risk factors and treatment modalities. Here we give survival details for all cancers combined in Europe, correlating it with economic variables to suggest reasons for differences. Methods: We computed age and cancer site case- mix standardised relative survival for all cancers combined (ACRS) for 29 countries participating in the EUROCARE-5 project with data on more than 7.5 million cancer cases from 87 population-based…
The EUROCARE-5 study on cancer survival in Europe 1999-2007: Database, quality checks and statistical analysis methods
2015
Abstract Background Since 25 years the EUROCARE study monitors the survival of cancer patients in Europe through centralised collection, quality check and statistical analysis of population-based cancer registries (CRs) data. The European population covered by the study increased remarkably in the latest round. The study design and statistical methods were also changed to improve timeliness and comparability of survival estimates. To interpret the EUROCARE-5 results on adult cancer patients better here we assess the impact of these changes on data quality and on survival comparisons. Methods In EUROCARE-5 the survival differences by area were studied applying the complete cohort approach to…
Survival in patients with primary liver cancer, gallbladder and extrahepatic biliary tract cancer and pancreatic cancer in Europe 1999- 2007: Results…
2015
Abstract Background The EUROCARE study collects and analyses survival data from population-based cancer registries (CRs) in Europe in order to provide data on between-country differences in survival and time trends in survival. Methods This study analyses data on liver cancer, gallbladder and extrahepatic biliary tract cancers (“biliary tract cancers”), and pancreatic cancer diagnosed in 2000–2007 from 88 CRs in 29 countries. Relative survival (RS) was estimated overall, by region, sex, age and period of diagnosis using the complete approach. Time trends in 5-year RS over 1999–2007 were also analysed using the period approach. Results The prognosis of the studied cancers was poor. Age-stand…
Urinary tract cancer survival in Europe 1999-2007: Results of the population-based study EUROCARE-5
2015
Abstract Background This work presents relative survival estimates regarding urinary tract tumours among adult patients (age ⩾ 15 years) diagnosed in Europe. It reports on survival estimates of cases diagnosed in 2000–2007, and on survival time trends from 1999–2001 to 2005–2007. Methods Data on 677,340 adult urinary tract tumour patients, (429,154 cases of invasive and non-invasive bladder and 248,186 cases of invasive kidney cancers) diagnosed between 2000 and 2007 were provided by 86 population-based cancer registries from 29 European countries. The complete approach was used to estimate survival in 2000–2007; the period approach was used to estimate survival over time. Results The age-s…
