Determination of oestrogen receptor alpha (ER) represents at present the most important predictive factor in breast cancers. Data of ours and of other authors suggest that promising predictive/prognostic factors may also include pS2, metallothionein (MT) and CD24. Present study aimed at determining prognostic and predictive value of immunohistochemical(More)
INTRODUCTION Recent reports suggest that expression of the cyclooxygenase 2 (COX-2) enzyme may up-regulate expression of MDR1/P-glycoprotein (MDR1/P-gp), an exponent of resistance to cytostatic drugs. The present study aimed at examining the relationship between the expression of COX-2 and of MDR1/P-gp in a group of breast cancer cases. METHODS(More)
Circulating tumor cells (CTCs) are important targets for treatment and critical surrogate markers when evaluating cancer prognosis and therapeutic response. A sensitive methodology for detecting CTCs in gastric cancer (GC) patients is needed. In this study we demonstrate a device for enrichment and cultivation of CTCs. In total, 22 patients with GC, all(More)
The aim of this study was to examine the expression of ERM (ezrin, moesin) and Rho (RhoA, RhoB and Cdc42) proteins in breast cancer (BC) patients and to investigate the relationship between the sub-cellular localisation of these proteins and clinicopathological characteristics and patient survival. The expression and specific sub-cellular distribution of(More)
The role of HER-2 expression as a prognostic factor in gastric cancer (GC) is still controversial. The aim of the study was to asses HER-2 status, its correlations with clinicopathological parameters, and prognostic impact in GC patients. Tumor samples were collected from 78 patients who had undergone curative surgery. In order to evaluate the intensity of(More)
In parthanatos, a PARP-1 (poly (ADP-ribose) polymerase 1)-mediated cell death, dissipation of mitochondrial membrane potential, large-scale DNA fragmentation and chromatin condensation were observed. In contrast to apoptosis, it does not cause apoptotic bodies formation. Although PARP-1-mediated cell death presents loss of membrane integrity similar to(More)
BACKGROUND In ductal carcinoma in situ of the breast (DCIS), histologic diagnosis obtained before the definitive treatment is related to the risk of underestimation if the presence of invasive cancer is found postoperatively. These patients need a second operation to assess the nodal status. We evaluated the upstaging rate in patients with mass-forming(More)
In the paper the visualization of medical data sets by Samonn's mapping is tested. This mapping performs the projection of multidimentional data into the small size space. For the purpose of visualization the size is equal 2. The obtained results were verified with the results of statistical approach. The application of Samonn's mapping seems to be(More)
Polo-like kinase 1 (PLK1) is a serine-threonine kinase that plays a crucial role in the regulation of cell division. In addition, it acts as a modulator of the DNA damage response and as a novel factor in the maintenance of genome stability during DNA replication. The present study aimed to reveal the associations between PLK1 expression and(More)
BACKGROUND Commonly identified on screening mammography breast microcalcifications are the predominant manifestation of ductal carcinoma in situ (DCIS). The aim of this study was to investigate the association between clinico-radiological features and histological findings in patients with screen-detected DCIS.
