Subproject 4: Specification and Documentation of Metabolic and Neoplastic Diseases M. Trauner, Division of Gastroenterology and Hepatology, Department of Internal Medicine, MUG Co- Investigator: H. Samonigg, Division of Oncology, Department of Internal Medicine, MUG
Project aims Associate prospectively collected human tissue and blood samples with detailed patient information - Clinical presentation, disease course & outcome - Family history, life style, additional diseases, medication Cross-validate mouse models and corresponding human diseases - Metabolic liver diseases and liver cancer
Metabolic and neoplastic diseases Metabolism (obesity, diabetes, iron) & cancer - Liver, breast, colorectal, Chronic inflammatory liver / bowel disease cancer (end of a spectrum) - Fatty liver steatohepatitis cirrhosis HCC - Chronic hepatitis cirrhosis HCC - Ulcerative colitis dysplasia / DALM - CRC Underlying liver / GI disease + cancer
NAFLD: Spectrum of Hepatic Pathology Chronic metabolic liver disease leading to cancer Steatosis Steatohepatitis HCC Cirrhosis HCC Modified after: A. M. Diehl, AGA Slide Series
Prospective collection & annotation of patient samples Prospective collection of medical data and sera of patients undergoing liver and intestinal biopsies Serum samples from liver outpatients before, during and after therapy (including LTx) Serum samples from cancer outpatients before, during and after medical / surgical therapy
Lifestyle and family questionnaire Liver and oncology outpatient clinic Number of pages: 16, option for automatic scanning Time effort: 30 min for patients and 10 min for M.D. Patient acceptance: very high (99%) Personal and medical history: - Nutrition (3 pages) - Alcohol / nicotine consumption (2 p) - Physical activity (3 p, collaboration with Institute of Sports Medicine) - Past medical history (2 p) - Family history (5 p) - Medication (1 p) Number of life style questionnaires - Liver outpatient clinic: 105 - Oncology outpatient clinic: 741
