Description
Mortality from malignant diseases is directly linked to early metastasis and relapse. It is now possible to identify individual tumor cells in bone marrow biopsies and peripheral blood. Colorectal cancer is one of the leading places in the structure of cancer incidence and mortality, both in Russia and around the world. Studies have shown that after surgery the ability of tumor cells to the dissemination and implantation increases. The work contains 30 patients with the verified colorectal cancer with metastasis to the liver. To determine the CSC we have applied an analysis technology in CellSearch System ™ (Janssen Diagnostics, LLC). Our study of the number and frequency of detection of circulating tumor cells in peripheral blood of patients and control group demonstrates the reduction in the number of CTCs during laparoscopic surgery and changing the dynamics of the level of tumor cells in the form of reduction from the stage of the mobilization of the drug due to minimally invasive access, minimizing manipulation in the projection of the tumor and as a consequence, preventing the release into the blood stream of single tumor cells

CLINICAL AND MORPHOLOGICAL FACTORS AND PREDICTION PARAMETERS OF CELL CYCLE IN ESOPHAGEAL CANCER
DescriptionThe aim of the study is to compare the traditional clinicopathologic factors and prognosis of cell cycle parameters, such as ploidy, cell cycle kinetics, as well as the study of DNA content in the tumor tissue of patients with esophageal cancer. Cancer of the esophagus - a very aggressive malignant disease, most commonly manifested impaired swallowing. As a rule, this type of cancer pathology is characterized by unfavorable outcome. Ploidy and cell proliferation activity, defined by the content of the DNA of the tumor - synthesizing cells are one of the important indicators of the growth rate of malignancy and prognosis. The study was performed on tumor tissue fragments of the 30 patients operated on for cancer of the esophagus. DNA study - conducted in the open cell material aftercare. DNA cell content was determined by flow cytometry BD FACSCanto II. By studying the DNA-cytometric parameters, we found the prevalence of aneuploid tumors in 66.7%. It was shown that DNAcytometric parameters are independent of gender. Major weight of diploid and aneuploid cell tumors of the esophagus was in G0 / 1 phase of the cell cycle. Comparative analysis of DNA - cytometric parameters and the degree of differentiation of esophageal tumor revealed a prevalence of aneuploid tumors in all the test cases. content distribution pattern of tumor cells was found in the G0 / G1-, G2 + M -, S - phase of the cell cycle at different stages of the disease

Description
While studying the content of hypoxia-inducible factor 1-alpha and vascular endothelial growth factor in the tumor tissue, oral fluid and peripheral blood of 141 patients with oral mucosa cancer T1-3N0-2M0, it was shown that the development of purulent inflammatory postoperative complications in patients with oral mucosa cancer is associated with an increased expression of HIF-1α in the tissue and its translocation from the cytoplasm to the nucleus, activation of the neoangiogenesis processes. It is informative to determine HIF-1α factor in the blood serum, which, for further development, can be used as a non-invasive diagnostic marker to predict the postoperative course in this category of patients

PROGNOSTIC SIGNIFICANCE OF LYMPHOCYTIC INFILTRATION IN VULVAR CANCER PATIENTS
DescriptionA retrospective immunohistochemical study of lymphocyte and macrophage infiltration in tumor tissue of 84 vulvar cancer patients with a long (over 2 years) and short (less than 2 years) remission was performed to determine a possible role of immunologic microenvironment of tumors in maintaining remission. Vulvar cancer patients with a short remission period were aged 46-85 years, mean age 67 years. 15.8% of them had stage I of the disease, 21% - stage II, 47.4% - stage III and 15.8% - stage IV. The average duration of remission in this group was 11 months. Patients with a long remission period were aged 27-71 years, mean age 48 years. 38.5% of them had stage I of the disease, 53.8% - stage II and 7.7% - stage III. The average duration of remission in this group was 8 years. Histological study showed squamous cell carcinoma in all patients. Stroma and parenchyma of tumor tissues demonstrated lymphocyte and macrophage infiltration of various degrees with the predominance of T-lymphocytes. CD8+ cells prevailed in tumor tissue of patients with a long remission period (over 2 years), while a higher level of CD4+ Т-lymphocytic infiltration was associated with a short remission (less than 2 years) and a poor prognosis. These differences allow prediction of the vulvar cancer course and its early or late recurrence
