Prognostic factors in malignant melanoma
Třešková, Inka ; Topolčan, Ondřej (advisor) ; Pizinger, Karel (referee) ; Nekulová, Miroslava (referee)
Background: Malignant melanoma is one of the most malignant types of skin cancer. Incidences are on the rise worldwide and in the Czech Republic an increase of 5% in diagnosed cases is noted each year. Early detection and early surgical removal are associated with reduced mortality. The strong aggressiveness of this malignant disease is caused by its local invasive growth and tendency to metastasize early. Aim of the study: The malignant melanoma is highly metabolically active tumor that releases a number of enzymes, cytokines, growth hormones and other molecules. The aim of this work was to determine the usability of preoperative and postoperative serum and plasma levels of biomarkers in primary diagnosis of tumor activity and in the postoperative follow-up care. These findings would be of clinical relevance for the patient's prognosis, modification of multimodal treatment and follow-up of patients with malignant melanoma. Methods: We measured circulating levels of several biomarkers in a group of 77 patients with malignant melanoma and cohort of 34 patients without cancer as a control group. Using routine immunoassays and novel multiplex xMAP technology, we measured: thymidine kinase, tissue polypeptide specific antigen, protein S100A, osteoprotegerin, osteopontin , insulin-like growth factor 1...

of dissertation thesis Prognostic and Predictive Factors in Breast Cancer The mRNA Expression of Selected Genes in Normal and Tumor Breast Tissue Samples and Theirs Clinical Value in Breast Cancer L.Šefrhansová Background: The aim of this work was to describe and to evaluate possibilities of prognosis and prediction in breast cancer. Within the framework of this study-work we carry out a prospective clinical study. The aim of this prospective study was to detect mRNA MMP-7, p53 and TIMP-1 expression in normal and tumor breast tissue samples and to determine the clinical and prognostic significance of our results. Prognosis and prediction: The tumor size, lymph node status, presence of distant metastasis, differentiation of the tumor, perivascular invasion, mitotic activity, expression of ER, PR and HER2 receptors are the basic prognostic factors in breast cancer. Age under/above 35 years was included among independent prognostic breast cancer factors in 2005. It is approved to use uPA/PAI to assess prognosis in node negative breast cancer patients. The hormone receptor status and HER-2 receptor status are the only two predictive markers associated with the target therapy. OncotypeDX analysis could be use to predict the disease recurrence interval of patients with estrogen positive and node negative...
