Studies on which it's performed


Competencies and learning outcomes

Basic understanding of advances in the field of molecular medicine in gastroenterology and their possible application in every day clinical practice.


Introduction to the principles involved in cancer development and progression, based on the model of gastrointestinal tumors. Review of molecular changings in oncogenes, tumor supressor genes and mismatch repair genes relating to illneses of the gastrointestinal tract will be given. Course topics include the genetics of hereditary and sporadic colon cancer, familial adenomatous polyposis (FAP) and human nonpolyposis colon cancer (HNPCC, Lynch syndrome). The gastric carcinoma is second most freequent gastrointestinal tumor in patients with HNPCC and the lectures will include the genetics of hereditary and sporadic gastric cancer. Course topics will be also the most recent findings in: molecular genetics of other human polyposis syndromes (Syndroma Gardner, Peutz-Jeghers, juvenile polyposis); molecular genetics of inflammatory bowel disease (IBD) (ulcerative colitis, Crohn’s disease); molecular genetics of pancreatitis and pancreatic adenocarcinoma. Molecular genetics of GEP-NETs tumors. Chemoprevention is another approach to decrease the incidenece of colorectal cancer in the general population. One of the topics of this course will be the role of COX-2 in the tumorigenesis and as a new molecular target in chemoprevetion and treatment of gastrointestinal tumors. Nutrigenomics, nutrigenetics of gastrointestinal tumors. Pharmacogenomics and pharmacogenetics of gastrointestinal tumors, importance of SNPs and mutations in genes for drug metabolism, response to therapy, toxicity and resistence to therapy. Seminar topics will include: molecular diagnostics of hereditary gastrointestinal tumors, presymptomatic diagnostics, pharmacogenetics, interpretation of the results of molecular-genetics analysis (mutation detection and "linkage" analysis).
