Mucoepidermoid carcinoma (MEC) is the most common of salivary glands. Here, we have used two large patient cohorts with MECs comprising 551 tumors to study clinical, histological, and molecular predictors survival. One cohort (n = 167), known CRCT1/3-MAML2 fusion status, was derived from Hamburg Reference Centre (HRC; graded AFIP Brandwein systems) other 384) population-based Cancer Registry North Rhine-Westphalia (LKR-NRW; system). The reliability both grading systems excellent 155)....
In contrast with breast cancers (BCs) in other parts of the world, most previous studies reported that majority BCs sub-Saharan Africa are estrogen-receptor (ER) negative. However, a recent study using US SEER database showed proportion ER-negative BC is comparable between US-born blacks and West-African born but substantially lower East African-born blacks, over 74% patients Ethiopians or Eritreans. this paper, we provide first report on Ethiopia, relation to progesterone-receptor (PgR)...
Background: Even though traumatic brain injury (TBI) is a major cause of morbidity and mortality in children around the globe, population-based nation-wide data to assess burden TBI scarce. Methods: Based on diagnosis related groups from hospital data, we extracted all TBI-related hospitalizations <18 years Germany between 2014 2018. We calculated crude, age-specific standardized incidence rates for hospitalizations, imaging, intracranial injury, neurosurgery, mortality. Results: Out...
Testicular cancer survival rates improved dramatically after cisplatin-based therapy was introduced in the 1970s. However, chemotherapy and radiation are potentially carcinogenic. The purpose of this study to estimate risk developing second primary cancers including associated with histologic type (seminoma non-seminoma) among testicular survivors Germany. We identified 16 990 1401 cases population-based registries East Germany (1961-1989 1996-2008) Saarland (a federal state West Germany;...
Estimating equations are recommended by clinical guidelines as the preferred method for assessment of glomerular filtration rate (GFR). The aim study was to compare population-based prevalence estimates decreased kidney function in Germany defined an estimated GFR (eGFR) <60 ml/min/1.73m2 using different equations. included 7001 participants German Health Interview and Examination Survey Adults 2008–2011 (DEGS1) whom Modification Diet Renal Disease equation (MDRD), revised Lund-Malmö (LM),...
In 2012 the age-standardized acute myocardial infarction (AMI) mortality rate was in federal state Saxony-Anhalt 67 deaths per 100.000 whereas Germany AMI-rate 47 100.000. The therefore 43 % above national average. Many factors may explain this above-average AMI rate: First, prevalence of cardiovascular risk (e.g. arterial hypertension, diabetes mellitus, smoking) is highest among all Federal States Germany. Second, structural health care for patients with potentially deficient insufficient...
This cohort study concerns the effect of skin cancer screening (SCS) on medical treatment intensity in patients with cancer.Routine data from persons aged 35 to 99 who were insured by AOK health insurance company used identify received a diagnosis malignant melanoma or non-melanocytic 2014 2015, either through without screening. These included studies. The routine contained no information tumor stages grading. Tumor-associated rates hospital admission, contact physicians outpatient practice,...
The planned nationwide implementation of mammography screening 2007 in Germany will increase the occurrence mammographically detected breast abnormalities. These abnormalities are normally evaluated by minimal invasive core biopsy. To minimize false positive and negative histological findings, quality assurance pathological evaluation biopsies is essential. Various guidelines for cancer diagnosis recommend applying B-classification histopathological categorization. However, to date there...
