The urgency of the problem. The incidence of various thromboembolic complications in patients with oncopathology reaches 5-12%. When treating VTE in patients with oncology it is necessary to choose between two generally recognized alternatives. The recommended two-component scheme of the initiating phase of anticoagulant therapy with subsequent long-term admission of VKA is fraught with the development of clinically significant bleeding during the initial selection of the dose of warfarin and an increased risk of recurrence of VTE...

BACKGROUND: Germline mutations in the coding sequence of the tumour suppressor APC gene give rise to familial adenomatous polyposis (which leads to colorectal cancer) and are associated with many other oncopathologies. The loss of APC function because of deletion of putative promoter 1A or 1B also results in the development of colorectal cancer. Since the regions of promoters 1A and 1B contain many single nucleotide polymorphisms (SNPs), the aim of this study was to perform functional analysis of some of these SNPs by means of an electrophoretic mobility shift assay (EMSA) and a luciferase reporter assay...

Ovarian carcinoma represents a heterogeneous group of malignant epithelial tumors which could be divided into two fundamental groups: Type I (endometrioid carcinoma, clear cell carcinoma, low grade serous carcinoma, mucinous carcinoma and more rare seromucinous carcinoma and malignant Brenner tumor) and type II (high grade serous carcinoma - HGSC). HGSC is the most frequent ovarian carcinoma which may be etiologically linked to inactivation of tumor suppressor genes BRCA1/2 and TP53 and differs from type I carcinomas by higher aggressiveness, tendency to peritoneal spread and worse prognosis...

Thanks to the numerous studies that have been carried out recently in the field of cytosolic DNA sensing, STING (Stimulator of Interferon Genes) is now recognized as a key mediator of innate immune signaling. A substantial body of evidence derived from in vivo mouse models demonstrates that STING-regulated pathways underlie the pathogenesis of many diseases including infectious diseases and cancers. It has also become evident from these studies that STING is a promising therapeutic target for the treatment of cancer...

Several highly prevalent human diseases are associated with immunopathology. Alterations in the immune system are found in such life-threatening disorders as cancer and atherosclerosis. Monocyte activation followed by macrophage polarization is an important step in normal immune response to pathogens and other relevant stimuli. Depending on the nature of the activation signal, macrophages can acquire pro- or anti-inflammatory phenotypes that are characterized by the expression of distinct patterns of secreted cytokines and surface antigens...

To determine the biochemical disorders in the blood coagulation mechanism associated with oxidative stress parameters of the antioxidant status were examined in platelets of 57 colorectal cancer patients, (including 21 patients before and after surgery), and 40 healthy individuals. We determined the total content of nitric oxide (NOx), levels of superoxide dismutase (Cu/ZnSOD), glutathione and malondialdehyde (MDA). Before treatment, we observed the changes in the antioxidant defense system of platelets, which did not depend on the prevalence of malignancy: elevated levels of SOD by 16% (p<0...

In this review we summarize the results of studies employing high-throughput methods of profiling of HPV-associated cervical intraepithelial neoplasia (CIN) and squamous cell cervical cancers at key intracellular regulatory levels to demonstrate the unique identity of the landscape of molecular changes underlying this oncopathology, and to show how these changes are related to the 'natural history' of cervical cancer progression and the formation of clinically significant properties of tumors. A step-wise character of cervical cancer progression is a morphologically well-described fact and, as evidenced by genome-wide screenings, it is indeed the consistent change of the molecular profiles of HPV-infected epithelial cells through which they progressively acquire the phenotypic hallmarks of cancerous cells...

BACKGROUND: There is significant inter-observer variation amongst the neuro-pathologists in the typing, subtyping, and grading of glial neoplasms for diagnosis. Centralized pathology review has been proposed to minimize this inter-observer variation and is now almost mandatory for accrual into multicentric trials. We sought to assess the concordance between neuro-pathologists on histopathological diagnosis of glioblastoma. MATERIALS AND METHODS: Comparison of local, institutional, and central neuro-oncopathology reporting in a cohort of 34 patients with newly diagnosed supratentorial glioblastoma accrued consecutively at a tertiary-care institution on a prospective trial testing the addition of a new agent to standard chemo-radiation regimen...

A molecular analysis has three major roles in modern oncopathology--as an aid in the differential diagnosis, in molecular monitoring of diseases, and in estimation of the potential prognosis. In this report we review the application of the molecular analysis in a group of patients with mantle cell lymphoma (MCL). We demonstrate that detection of the cyclin D1 mRNA level is a molecular marker in 98% of patients with MCL. Cyclin D1 quantitative monitoring is specific and sensitive for the differential diagnosis and for the molecular monitoring of the disease in the bone marrow...

Between age diseases two are standing out: oncological and cardiovascular ones. They give a main contribution to mortality of the population. Those who avoid these diseases have a chance to live longer. The author suggests a hypothesis of one common factor, which deviation leads to oncology or cardiovascular illness. Such factor is a production of nitric oxide in the organism, which depends on the geomagnetic activity (GMA). At excess production of nitric oxide the risk of oncopathology (breast cancer, bladder and lung cancer and others) is increased...
