[Immunoscore and Its Predictive Value for Colorectal Cancer].

Recent studies suggest that immune  classification (immune-score) in cancer patients has a prognostic value in some cases that seems to be superior to the AJCC/ UICC TNM  classification. The clinical outcome can vary significantly among patients with a particular diagnosis within the same TNM stage. Immunoscore methodology quantifies and detects different types of immune cells in tumor tissue, and also determines the density of their infiltration and localization at the tumor site.

Cellular and humoral immunodeficiency in breast cancer patients resistant to hormone therapy.

In view of the fact that insufficiency in immune response often correlates with poor prognosis, research in recent years has focused on the task of describing the precise status and function of the immune system and its possible effect on cancer patients. Although more than two thirds of treated patients respond to endocrine therapy, most patients with metastatic breast cancer develop a resistance to it. Estrogen modulates angiogenesis, partially through its effects on vascular endothelial growth factor (VEGF).

Impaired deoxyribonuclease I activity in patients with inflammatory bowel diseases.

Background and Aims. Deoxyribonuclease I (DNaseI) is an endonuclease that facilitates chromatin breakdown and promotes susceptibility to autoimmune disorders. The aim of current study was to investigate serum DNase I activity in patients with inflammatory bowel diseases (IBD).

Anti-inflammatory effect of biological treatment in patients with inflammatory bowel diseases: calprotectin and IL-6 changes do not correspond to sRAGE changes.

Aim: The main objective was to examine the relationship between the soluble receptor for advanced glycation end products (sRAGE) and calprotectin concentrations in faeces and serum of patients with inflammatory bowel diseases (IBD) during biological treatment with infliximab.

Materials And Methods: A total of 29 IBD patients treated with infliximab were evaluated. Calprotectin and sRAGE in serum and faeces and serum IL-6 and CRP were measured during the induction regimen of infliximab treatment at weeks (W) 0, 2 and 10.

Preoperative transforming growth factor-beta 1 (TGF-beta 1) plasma levels in operable breast cancer patients.

Objectives: The aim of this project was to search for new risk prognostic markers in the early stage of breast cancer. We tested preoperative plasma transforming growth factor - beta 1 (TGF- beta 1) levels in patients with operable breast cancer. Correlation with traditional prognostic markers and with positivity/negativity sentinel lymph node was evaluated.
