e19628 Background: Fatigue is one of the most frequent symptoms in cancer patients, characterized by profound fatigue that is not relieved by rest. This symptom can be identified at the time of diagnosis and could affects up to 90% of patients undergoing cancer treatment. There are some instruments available in the literature that can characterize the presence of fatigue through clinical questioning. Methods: Considering the large population of patients with metastatic colorectal cancer treated with chemotherapy and the prevalence of fatigue in these patients, this study evaluated the presence of fatigue in 27 metastatic colon cancer patients before the first, second, third and fourth cycles of fist line palliative chemotherapy regimen containing CAPOX (capecitabine and oxaliplatin) by applying the evaluation questionnaire FACIT-F fatigue. Results: The results post Friedman chi-squared test demonstrated that there was no improvement of fatigue during these four cycles of CAPOX palliative chemotherapy (p=0,2574). The FACIT-G analysis demonstrated no worsening of quality of life (p=0,2411) during and between the four cycles of chemo. All different parameters included in FACIT-F questionnaires: emotional (p=0,2629), physical (p=0,3199), familiar (p=0,1456), functional (p=0,8662) and specific fatigue topic (p=0,7569) confirmed no difference between the cycles. Conclusions: Despite the metastatic stage of colon cancer patients and concurrent chemotherapy treatment, there was no fatigue improvement during the four first CAPOX chemo cycles courses and there was the maintenance of quality of life.

Aim. To investigate formation of neutrophil extracellular traps (NETs) and their impact on fibrinolysis in patients with colon cancer.Materials and methods. The study was performed in two groups. The experimental group consisted of patients with stage 2–3 non-metastatic colon cancer (n = 17, average age – 67 years). The control group included healthy volunteers matched by sex and age (n = 30, average age – 68 years). An experimental model was created from the whole blood. It included platelet-poor plasma and an isolated culture of neutrophils, previously induced to NETosis by adding 100 nmol PMA. The samples were incubated for 4 hours, then the test tubes were centrifuged to pellet cells and their remnants, and the plasma was transferred for subsequent examination. The plasma incubated with intact neutrophils was used as a control. The levels of interleukin-8 (IL-8) and P-selectin glycoprotein ligand-1 (PSGL-1) were used to determine the degree of cell activation. NETosis was confirmed by enzyme-linked immunosorbent assay (ELISA) and fluorescent microscopy. Fibrinolysis was assessed using the thrombodynamics test. The results were compared with the levels of fibrinolytic system components measured by flow cytometry.Results. In the control group, NETosis induction contributed to pronounced neutrophil activation that was accompanied by an increase in the IL-8, PSGL-1, and plasminogen levels, a decrease in PAI-1, and enhancement of fibrinolysis, compared with the intact samples. Higher levels of IL-8, PSGL-1, plasminogen, and PAI-1 and intensified fibrinolysis were detected in the intact samples. However, PMA-induced NETosis did not result in an increase in the degree of activation and significant changes in the given parameters.Conclusion. NETosis promotes both formation and lysis of fibrin clots. However, in cancer patients, suicidal NETosis does not contribute to fibrinolysis due to intracellular protease depletion, which may be one of the mechanisms causing hypercoagulation and insufficient fibrinolysis in cancer.

e15535 Background: VEGF receptors have an important role for inhibiting adaptive immun response in colon cancer. Therefore, we analyzed VEGF receptors in circulating T cell subsets according to stage in colon cancer patients. Methods: The prospective study group consisted of 50 patients with histologically confirmed colon cancer and 30 person without any cancer history as a control group. Peripheral blood specimens were collected from the patients after the diagnosis before inducing chemotherapy and radiotherapy. Patients with active infections or autoimmune disorders, who were treated with steroids and antibiotics in the last four weeks before the study enrollment were excluded from the study group. VEGFR2 expressions in circulating T cell subsets (Th1, Th2, Th17, CTL) were analyzed by flow cyctometry. Results: Age and gender were not different between the all study groups. Mean circulating CD4+ folicullar cells were less in colon cancer patients (9.54%±3.99) than the control group (12.03%±4.34), (p < 0.01). Mean circulating CD8+ follicular cells were higher in metastatic colon cancer (n = 26) 2.48% ± 1.68, than the non-metastatic colon cancer patients (n = 24) 1.63% ± 1.37, (p = 0.02). Mean VEGFR2 expressions in Th1 cells were higher in colon cancer patients 248.8 (Mean Flourescein intensity-MFI) than the control group 224.6, (P = 0.006). Mean VEGFR2 expressions in CTL were higher in colon cancer patients (381.8) than the control group (284.7), (p < 0.001). PD-1 expressions were not different between the colon cancer patients and the control group in all circulating T cell subsets. Mean VEGFR2 expressions in Th17 cells were higher non-metastatic colon cancer patients than the metastatic colon cancer patients (326.5 and 268.4 MFI, respectively, p = 0.02). Conclusions: VEGFR2 expressions are increased in circulating Th1 and CTL subsets in colon cancer patients. Whereas PD-1 expressions were not different in circulating T cell subsets than the control. VEGFRs may play an important role for the inhibition of circulating T cell subsets in colon cancer.
