Physical, chemical and viral carcinogenesis, changes in cancer cell metabolism.
|
Physical
factors involved in the development of cancer: a) the influence of UV radiation
b) the influence of ionizing radiation c) the involvement of other physical
factors - foreign body chronic mechanical damage etc. Chemical carcinogenesis
a) types of chemical carcinogens b) mechanisms of action of chemical
carcinogens. Viral carcinogenesis a) DNA oncogenic viruses - mechanism of
induction of cancer b) RNA oncogenic viruses * induction of primary hepatoma by
HCV * retroviruses and cancer. Metabolic changes in cancer cells, Warburg
effect. |

Mechanisms of tumorigenesis (pathobiochemistry of malignant transformation).
|
What is a malignant tumor, genetics and epigenetics. Disorders of cell development and differentiation, cancer stem cells. Immortalization, role of telomeres. Tumor transformation, signaling disorders leading to tumor transformation, causes of changes in signaling pathways affecting cell proliferation (RTKs, cytokine receptors, Wnt signaling, TGF-beta, Rb), apoptosis (DRs, caspases, role of mitochondria) and DNA repair pathways (HNEJ, HR, MMR). |

DNA-based Diagnostics in Oncology
|
Molecular diagnostics of hereditary cancer syndromes. Inherited gene mutations, single base-pair substitutions, short gene deletions, small insertions, large genomic rearrangements. The analysis of mutations in inherited predispositions to cancer (PCR, HRM, Sanger sequencing, MLPA, next gen sequencing). Sporadic cancers, types of somatic mutations. large-scale mutations, gene amplifications, deletions of large chromosomal regions, chromosomal translocations and their analysis. Microsatellite instability in human tumors and detection. Minimal residual disease and detection. |

Principles of cancer development (tumor microenvironment, regulation of neovascularization, metastatic cascade).
|
Tumor heterogeneity and mechanisms of its origin (clonal evolution, cancer stem cells). Tumour microenvironment and its importance in carcinogenesis. Types and molecular mechanisms of neovascularization (with emphasis on angiogenesis and vasculogenesis), characteristics of tumor vasculature. Regulators of neovascularization, VEGF. Metastatic cascade, EMT, different invasion strategies, infiltration and colonization of target organs. Angiogenesis and metastasis as possible therapeutic targets. |

Biomarkers of cancer diseases
|
Tumor biomarkers - definition and division; diagnostic, monitoring, screening, prognostic, predictive and pharmacodynamic biomarkers, special cases - oncofetal biomarkers; Examples of use in clinical practice - organ specificity, tumour detection and diagnosis, release into the blood, prediction of tumour risk, differential diagnosis of tumours, cancer staging, monitoring of cancer treatment efficacy, detection of residual cancer and tumour recurrence after treatment, searching for patients at risk in the general population; Sensitivity, specificity, positive and negative predictive value, ROC curves, Kaplan-Meier survival function estimation; prediction of cancer prognosis, decision making on treatment selection, drug dosage adjustments. |
