Multiple myeloma is a chronic, incurable but highly treatable neoplasm. Recent population-based studies have shown improvements in survival for patients diagnosed in the early 21st century. Here, we examine trends in survival for patients diagnosed with multiple myeloma in Germany and the United States (US) between 2002 and 2010. Data were extracted from 11 population-based cancer registries in Germany and from the Surveillance, Epidemiology and End Results database in the US. Myeloma patients aged 15-74 years with diagnosis and follow-up between 1997 and 2010 from Germany and the US were included. Period analysis was employed to assess trends in 5-year relative survival in Germany and the US between 2002-04 and 2008-10. Age-adjusted 5-year relative survival increased from 47·3% to 53·8% in Germany and from 39·8% to 53·2% in the US between 2002-04 and 2008-10. There was a strong age gradient with lower survival among older patients, which persisted over time and was more pronounced in Germany than the US. Five-year relative survival estimates for patients diagnosed with multiple myeloma below 75 years of age steadily increased throughout the first decade of the 21st century and reached levels above 50% in both Germany and the US, probably reflecting the increased use of newer agents in myeloma treatment. © 2015 John Wiley & Sons Ltd.

Background and Aim: This study aims to examine survival for gastric lymphomas and its main subtypes, mucosa-associated lymphoid tissue lymphoma (MALT), and diffuse large B-cell lymphoma (DLBCL), in Germany and in the United States. Methods: Data for patients diagnosed in 1997-2010 were used from 10 population-based German cancer registries and compared to the data from the US Surveillance, Epidemiology and End Results (SEER) 13 registries database. Patients age 15-74 diagnosed with gastric lymphomas were included in the analysis. Period analysis and modeled period analysis were used to estimate 5-year and 10-year relative survival (RS) in 2002-2010 and survival trends from 2002-2004 to 2008-2010. Results: Overall, the database included 1534 and 2688 patients diagnosed with gastric lymphoma in 1997-2010 in Germany and in the United States, respectively. Survival was substantially higher for MALT (5-year and 10-year RS: 89.0% and 80.9% in Germany, 93.8% and 86.8% in the United States) than for DLBCL (67.5% and 59.2% in Germany, and 65.3% and 54.7% in the United States) in 2002-2010. Survival was slightly higher among female patients and decreased by age for gastric lymphomas combined and its main subtypes. A slight, nonsignificant, increase in the 5-year RS for gastric lymphomas combined was observed in Germany and the United States, with increases in 5-year RS between 2002-2004 and 2008-2010 from 77.1% to 81.0% and from 77.3% to 82.0%, respectively. Five-year RS of MALT exceeded 90% in 2008-2010 in both countries. Conclusions: Five-year RS of MALT meanwhile exceeds 90% in both Germany and the United States, but DLBCL has remained below 70% in both countries. © 2015 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.

Background: Colorectal cancer is the most common cancer in Germany and the second most common cause of cancer-related deaths in both men and women. The aim of this study is to provide detailed analysis of recent developments in survival of colorectal cancer patients using newly available data on a national basis. Methods: We included data from 11 German cancer registries covering a population of 33 million inhabitants. Period analysis and modelled period analysis were used to provide most up-to-date estimates of 5-year relative survival in 2002-2006. Results: The analysis was based on records of 164 996 colorectal cancer patients. Five-year relative survival was 63.0% overall, decreased with age and was significantly higher among women than among men in patients under 75 years. Overall age-adjusted 5-year relative survival increased from 60.6 to 65.0% over the period 2002-2006. Significant increase in survival was only observed in patients with localised or regional disease. Highest subsite-specific survival was observed in patients with cancer in descending (67.7%) and ascending (66.5%) colon. Conclusion: Survival of patients with colorectal cancer continued to increase in the early 21st century in Germany, with 5-year relative survival reaching 65% in 2006. However, lack of progress still persisted in patients with advanced disease. © 2012 Cancer Research UK.

Lung Cancer | Year: 2015

Objectives: Lung cancer is the most common cancer-related death worldwide. In Germany it accounts for 25% of cancer deaths in men, and 14% in women. The aim of this study is to provide an overview of 5-year relative survival by sex, age, histology, and tumour stage in Germany representing a population of 26.7 million people. Materials and methods: The study is based on a pooled German dataset including data from 12 population-based cancer registries covering around one third of the German population. A total of 132,612 patients diagnosed with lung cancer from 2002 to 2010 were included in the analysis. Survival estimates for the time period 2007-2010 were calculated using period analysis. Differences in survival between sexes were tested for statistical significance by model-based period analysis (poisson regression model). The relative excess risk (RER) of death (women vs. men) was extracted from the model with the p value for the difference in RER. Results: The overall age adjusted 5-year relative survival was 15.5% (standard error (SE) 0.2) for men and 20.3% (SE 0.3) in women. Survival differed markedly according to age (men: <60 years 18.5% vs. 80+ years 8.4% and women 23.7% vs. 10.6%, respectively), histology (largest difference between histological groups: men 25.7 and women 44.4% points) and stage (men: UICC Ia 62.9%, vs. UICC IV 4.6% and women 75.2% vs. 7.0%, respectively). Our study showed survival advantages for women compared to men, most notably in younger aged patients (RER 0.83, p< 0.0001), patients with adenocarcinoma (RER 0.80, p< 0.0001), and patients with lower stage cancer (RER 0.62, p< 0.0001). Conclusions: This study presents up-to-date survival estimates for lung cancer in Germany. Compared to other European countries survival was relatively high. Women showed higher survival than men independent of age, histology and stage. The reasons for the survival differences require further clarification. © 2015 Elsevier Ireland Ltd.

Background: Cancer care services including cancer prevention activities are predominantly localised in central cities, potentially causing a heterogeneous geographic access to cancer care. The question of an association between residence in either urban or rural areas and cancer survival has been analysed in other parts of the world with inconsistent results. This study aims at a comparison of age-standardised 5-year survival of cancer patients resident in German urban and rural regions using data from 11 population-based cancer registries covering a population of 33 million people. Material and methods: Patients diagnosed with cancers of the most frequent and of some rare sites in 1997-2006 were included in the analyses. Places of residence were assigned to rural and urban areas according to administrative district types of settlement structure. Period analysis and district type specific population life tables were used to calculate overall age-standardised 5-year relative survival estimates for the period 2002-2006. Poisson regression models for excess mortality (relative survival) were used to test for statistical significance. Results: The 5-year relative survival estimates varied little among district types for most of the common sites with no consistent trend. Significant differences were found for female breast cancer patients and male malignant melanoma patients resident in city core regions with slightly better survival compared to all other district types, particularly for patients aged 65 years and older. Conclusion: With regard to residence in urban or rural areas, the results of our study indicate that there are no severe differences concerning quality and accessibility of oncological care in Germany among different district types of settlement. © 2014 Elsevier Ltd.

We aimed at investigating the distribution and risk of all second discordant primary cancers (SDPCs) after a specific first primary cancer in Germany and Sweden to provide etiological understanding of SDPCs and insight into their incidence rates and recording practices. Among 1,537,004 survivors of first primary cancers in Germany and 588,103 in Sweden, overall 80,162 and 32,544 SDPCs were recorded, respectively. Standardized incidence ratios (SIRs) of all SDPCs were elevated at levels between 1.1 and 2.1 after 23 (out of overall 29) cancers in Germany and at levels between 1.1 and 1.6 after 24 cancers in Sweden, and among them, elevated SIRs were found after 19 cancers in both populations. Decreased SIRs at levels ranging from 0.5 to 0.9 were found for some cancers with poor prognosis in Germany only. We found elevated risk after 19 out of 29 cancers in both countries, suggesting common etiology of SDPCs after most of first cancers and registration similarity. Decreased risks after some fatal cancers were found only in Germany, which may be attributed to reporting practices or missed death data in Germany. © 2015 Elsevier Ireland Ltd.
