Recent cancer survival in Germany: An analysis of common and less common cancers
The monitoring of cancer survival by population-based cancer registries is a prerequisite to evaluate the current quality of cancer care. Our study provides 1-, 5- and 10-year relative survival as well as 5-year relative survival conditional on 1-year survival estimates and recent survival trends for Germany using data from 11 population-based cancer registries, covering around one-third of the German population. Period analysis was used to estimate relative survival for 24 common and 11 less common cancer sites for the period 2007-2010. The German and the United States survival estimates were compared using the Surveillance, Epidemiology and End Results 13 database. Trends in cancer surviv…
Screening for gastric cancer using exhaled breath samples.
Abstract Background The aim was to derive a breath-based classifier for gastric cancer using a nanomaterial-based sensor array, and to validate it in a large screening population. Methods A new training algorithm for the diagnosis of gastric cancer was derived from previous breath samples from patients with gastric cancer and healthy controls in a clinical setting, and validated in a blinded manner in a screening population. Results The training algorithm was derived using breath samples from 99 patients with gastric cancer and 342 healthy controls, and validated in a population of 726 people. The calculated training set algorithm had 82 per cent sensitivity, 78 per cent specificity and 79 …

Survival in patients with acute myeloblastic leukemia in Germany and the United States: Major differences in survival in young adults
Previous epidemiologic studies on AML have been limited by the rarity of the disease. Here, we present population level data on survival of patients with AML in Germany and the United States (US). Data were extracted from 11 population-based cancer registries in Germany and the Surveillance, Epidemiology, and End Results (SEER13) database in the US. Patients diagnosed with AML in 1997-2011 were included. Period analysis was used to estimate 5-year relative survival (RS) and trends in survival in the early 21st century. Overall 5-year age-adjusted RS for patients with AML in 2007-2011 was greater in Germany than in the US at 22.8% and 18.8%, respectively. Five-year RS was higher in Germany t…
Potential of non-invasive breath tests for preselecting individuals for invasive gastric cancer screening endoscopy.
Background. Regular screening for gastric cancer (GC) is based on invasive upper gastrointestinal endoscopy and is limited to few high-incidence countries. As GC is a major cause of cancer death worldwide, a non-invasive, simple screening test is of value. We assessed the prevalence of preclinical GC and the corresponding numbers needed to screen (NNS) to detect GC cases both without and with preselection using breath tests from the literature in various populations. Methods. Using age- and sex-specific GC incidence data and rates of transition from preclinical to clinical GC, we estimated the prevalences of preclinical GC worldwide in populations aged 50–74 years, and we evaluated the accu…
Survival of patients with gastric lymphoma in Germany and in the United States
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 2008–2…
Associations of diet and lifestyle factors with common volatile organic compounds in exhaled breath of average-risk individuals.
Background Detection of diseases via exhaled breath remains an attractive idea despite persisting gaps in understanding the origin of volatile organic compounds (VOCs) and their relationship with the disease of interest. Data on factors potentially influencing the results of breath analysis remain rather sparse and often controversial. In this study, we aimed to investigate the associations of common VOCs in exhaled breath of average-risk individuals with socio-demographic and lifestyle factors, medical conditions as well as diet. Methods Alveolar breath samples of 1447 men and women were collected in the morning after fasting and were analyzed using gas-chromatography linked with mass-spec…
