Environmental risk factors for sporadic acoustic neuroma (Interphone Study Group, Germany)

2007

The only known risk factor for sporadic acoustic neuroma is high-dose ionising radiation. Environmental exposures, such as radiofrequency electromagnetic fields and noise are under discussion, as well as an association with allergic diseases. We performed a population-based case-control study in Germany investigating these risk factors in 97 cases with acoustic neuroma, aged 30 to 69 years, and in 194 matched controls. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated in multiple logistic regression models. Increased risks were found for exposure to persistent noise (OR=2.31; 95% CI 1.15-4.66), and for hay fever (OR=2.20; 95% CI 1.09-4.45), but not for ionising radiation …

BCL6: somatic mutations and expression in early-stage chronic lymphocytic leukemia

2009

BCL6 somatic mutations affect normal and tumoral post germinal center B-lymphocytes. Our objective was to analyse expression, mutations and polymorphisms in the BCL6 gene and to correlate those variables with the clinical outcome in early-stage chronic lymphocytic leukemia (CLL). CLL samples were used for characterisation of the mutational status of BCL6/ immunoglobulin variable heavy chain (IGHV) genes, and expression of BCL6 was determined by real time PCR and immunoblot. Out of 68 cases, 29% show somatic mutations on BCL6 which occur exclusively in IGHV mutated cases. They are single nucleotide substitutions located mainly in two short mutational hot spots. CLL cells express different le…

BRCA1/BRCA2 rearrangements and CHEK2 common mutations are infrequent in Italian male breast cancer cases

2008

Male breast cancer (MBC) is a rare and poorly known disease. Germ-line mutations of BRCA2 and, to lesser extent, BRCA1 genes are the highest risk factors associated with MBC. Interestingly, BRCA2 germ-line rearrangements have been described in high-risk breast/ovarian cancer families which included at least one MBC case. Germ-line mutations of CHEK2 gene have been also implicated in inherited MBC predisposition. The CHEK2 1100delC mutation has been shown to increase the risk of breast cancer in men lacking BRCA1/BRCA2 mutations. Intriguingly, two other CHEK2 mutations (IVS2+1G>A and I157T) and a CHEK2 large genomic deletion (del9-10) have been associated with an elevated risk for prostate c…

Survival of patients with non-Hodgkin lymphoma in Germany in the early 21st century.

2012

This study provides up-to-date and detailed cancer survival estimates of German patients with non-Hodgkin lymphoma (NHL, International Statistical Classification of Diseases 10th Revision [ICD-10] codes C82-C85) based on data from 11 cancer registries. Period analysis was used to calculate 5-year relative survival in 2002-2006, overall and by gender, age and histology. Comparison was made with patients with NHL in the United States (US) Surveillance, Epidemiology and End Results database in the same time period. Overall 5-year relative survival for patients with NHL in Germany in 2002-2006 was 62.8% and in the US was 65.1%. Survival decreased with age from 81.7% at age 15-49 to 46.5% at age…

Differences in incidence and survival of oral cavity and pharyngeal cancers between Germany and the United States depend on the HPV-association of th…

2017

Abstract Introduction The epidemiology of squamous cell oral cavity and pharyngeal cancers (OCPC) has changed rapidly during the last years, possibly due to an increase of human papilloma virus (HPV) positive tumors and successes in tobacco prevention. Here, we compare incidence and survival of OCPC by HPV-relation of the site in Germany and the United States (US). Materials and methods Age-standardized and age-specific incidence and 5-year relative survival was estimated using data from population-based cancer registries in Germany and the US Surveillance Epidemiology and End Results (SEER) 13 database. Incidence was estimated for each year between 1999 and 2013. Relative survival for 2002…

Occupation and risk of glioma, meningioma and acoustic neuroma: results from a German case-control study (interphone study group, Germany)

2010

Background: Several epidemiological studies have investigated the association between occupation and brain tumour risk, but results have been inconclusive. We investigated the association between six occupational categories defined a priori: chemical, metal, agricultural, construction, electrical/electronic and transport, and the risk of glioma, meningioma and acoustic neuroma. Methods: In a population-based case-control study involving a total of 844 cases and 1688 controls conducted from 2000 to 2003, detailed information on life-long job histories was collected during personal interviews and used to create job calendars for each participant. Job title, job activity, job number, and the s…

Incidence and long-term prognosis of papillary compared to clear cell renal cell carcinoma--a multicentre study.

2012

Abstract Aim of the study Papillary renal cell carcinoma (pRCC) is the second most common subtype of RCC after the conventional clear cell type (cRCC). However, its characteristics and prognosis have been less intensively investigated. The aim of our study was to examine the tumour characteristics and long-term prognosis of pRCC compared to clear cell RCC (cRCC). Methods In total, 4941 evaluable patients were subjected to either radical nephrectomy or nephron-sparing surgery for pRCC or cRCC at five centres in Germany (University Hospitals of Hannover, Homburg/Saar, Mainz, Ulm and Marburg) between 1990 and 2010. Results pRCC ( n  = 565) and cRCC ( n  = 4376) patients were comparable with re…

Incidence of lip malignancies in Germany-data from nine population-based cancer registries.

2017

Background The objective of this study was to analyse the incidence of lip malignancies in Germany. Methods Data from population-based cancer registries covering a population of 39 million inhabitants from 14 federal states were pooled. Lip malignancies were classified according to the International Classification of Diseases (ICD-10). Age-standardised incidence rates and annual percentage changes in the incidence trends of lip cancer (C00), melanoma of the lip (C43.0), and non-melanoma skin cancer of the lip (C44.0) were calculated. Results Lip cancer (C00) incidence rate was 0.57/0.15 per 100 000 (men/women) in 2003 and 0.52/0.18 in 2012. In women, the change was statistically significant…

Sexual desire and sexual activity of men and women across their lifespans: results from a representative German community survey

2007

OBJECTIVES To present data on sexual desire and sexual activity from a representative survey of men and women covering the total age range of the adult German population, as previous studies have usually been based on samples selected for gender (either men or women) and age (ageing populations). SUBJECTS AND METHODS A representative sample of 2341 men and women aged 18-93 years were surveyed to determine frequency and intensity of sexual desire and sexual activity, and their social, individual and interpersonal characteristics. RESULTS Sexual desire declined with advancing age; overall, men reported more frequent and stronger sexual desire than women. However, there were important interact…
