To evaluate serum levels of selected cytokine receptors in B-cell precursor acute lymphoblastic leukemia (B-ALL) and their association with acknowledged prognostic factors, relapse-free survival (RFS) and overall survival (OS).

A total of 42de novo adult B-ALL patients, 19BCR/ABL positive, were included in this study. Soluble receptor α for IL-2 (sIL-2Rα), soluble receptor for IL-6 (sIL-6R), soluble receptor for TNF-α type I and II (sTNFR-1, sTNFR-2) and matrix metalloproteinase-9 (MMP-9) were measured by biochip array technology at diagnosis and in complete remission (CR).

At diagnosis of B-ALL, we found significantly higher levels of sIL-2Rα, sIL-6R, sTNFR-1, sTNFR-2and significantly lower levels MMP-9in comparison with CR (p< 0.001in all cases). BCR/ABL positive patients had higher levels of sIL-2Rα at diagnosis (r= 0.484; p= 0.014). Serum levels of evaluated cytokines were not associated with achievement of CR after one cycle of induction therapy, RFS or OS.

Serum levels of all evaluated cytokines are significantly altered in newly diagnosed B-ALL reflecting activity of the disease. No significant correlations with response to first induction therapy, RFS or OS were found. Further studies with a longer follow-up will be needed.

Kavetsky Institute of Experimental Pathology, Oncology and Radiobiology of the National Academy of Science of Ukraine has been studying the mechanisms and specificities of individual radiation sensitivity (IRS) formation in professionals who work in the field of ionizing radiation, cancer patients and representatives of other population groups. Our data based on the use of G2-test in in vitro irradiated blood lymphocytes in late G2-period of cell cycle indicated an increased carcinogenic risk in professionals with high IRS. We suggest that the COVID-19 pandemic could make significant adjustments in the formation of IRS in professionals who have survived the disease and continue to work with ionizing radiation (IR). Increased systemic inflammatory activity, which persists for a long time in COVID-19 patients, in combination with low-dose range irradiation (professionals who continue to work with IR) and with local irradiation in the high-dose range (radiation therapy for cancer patients) may affect IRS. Repeated determination of IRS in professionals who have had COVID-19 infection, using chromosomal G2-radiation sensitivity assay will answer the question can SARS-CoV-2 coronavirus affect the IRS? The proposed hypothesis of the radiosensitivity evolution needs further experimental validation using a set of radiobiological indices to clarify the mechanism of IRS formation following COVID-19 infection. The detected changes (increase) of human IRS after COVID-19 must be taken into account for personalized planning of radiotherapy of COVID-19 cancer patients.
To study the levels of redox-forming molecules generated in tumor, adipose tissue (AT), neutrophils and platelets of patients with colorectal cancer (CRC) with normal body weight or obesity.

83samples of tumor tissue and 83samples of the AT taken at the distance of 5cm from the tumor as well as 83blood samples have been analyzed in the patients with CRC with metachronous lesions in liver. The comparison group consisted of 18patients who were surgically treated for ulcer. The rates of free radical generation were measured by electron paramagnetic resonance.

Free radical generation rate in tumor tissue and AT increased and nitrogen oxide (NO) levels decreased in patients with body mass index ≥ 25kg/m
as compared to the patients with normal body weight (p < 0.05). The superoxide generation activity in neutrophils of CRC patients exceeded about 7-fold the values obtained in neutrophils from patients with ulcer while the NO levels produced by neutrophils of CRC patients decreased significantly (p < 0.01). The same trends held true for the platelets.

In obese patients with CRC, superoxide-generating activity increases in cancer cells, AT, neutrophils and platelets. The obesity should be considered as the additional oncological risk representing the potent predictor for the events realized in obese patients such as oxidative stress, inflammation, insulin resistance and endothelial dysfunction.

Recently, bioactive ceramics based on hydroxyapatite (HAP) and tricalcium phosphate (TCP) have been preferred as implants in bone engineering.

To study bone regeneration under conditions of filling metaphyseal defects with the original HAP-TCP composition.

The experiment was carried out on inbred rats, the observation period was 2, 4, 8weeks. Morphological studies were carried out using light and electron microscopy.

In the dynamics of observation at 2, 4and 8weeks, a gradual arrangement of osteoclasts and osteoblasts on the surface of HAP-TCP was recorded, which indicates its high biocompatibility with bone tissue. During the experiment, the processes of resorption of implants, mineralization, proliferation of cellular elements of collagen and osteogenesis (osteoblasts and osteoclasts) and the formation of mature bone tissue were recorded.

Experimental studies of plastic bone defects proved the presence of the osteoinductive and osteointegrative effect of HAP-TCP composition, which contributes to a more dynamic uncomplicated course of reparative osteogenesis.

Recently one randomized trial and several phase II studies underscored that patients with metastatic colorectal cancer who progressed after an initial clinical benefit from anti-epidermal growth factor receptor (EGFR) treatment may further benefit from rechallenge with anti-EGFR therapy. Testing circulating tumor DNA (ctDNA) RAS status prior to anti-EGFR rechallenge seems a promising non-invasive method to predict and monitor response to anti-EGFR readministration.

To assess the capability of liquid biopsy ctDNA in exploring RAS status and in predicting outcome of metastatic colorectal cancer patients treated with anti-EGFR monoclonal antibody rechallenge.

Systematic review of literature and meta-analysis of the available evidence.

Data from four studies involving 117patients were available. All patients harbored RAS wild type tumors and derived benefit from first line anti-EGFR therapy. Of these, 65underwent plasma ctDNA before anti-EGFR treatment rechallenge and were eligible for analyses 35patients had RAS wild type ctDNA, and 30RAS mutated, indicating that 46% of patients underwent RAS status conversion after primary anti-EGFR therapy. Anti-EGFR rechallenge among patients with plasma ctDNA RAS wild type status was associated with a consistent benefit in progression free survival (hazard ratio (HR) 0.40, 95% confidence interval (CI) 0.22-0.70; p= 0.001; I
= 0) and overall survival (HR 0.37, 95% CI 0.16-0.85; p= 0.02; I
= 74%) when compared to its use among patients with plasma ctDNA RAS mutation. Patients with plasma ctDNA RAS wild type profile also performed statistically better in term of disease control rate, risk for disease progression at 3and 6months, and risk for death at 6and 12months.

RAS status assessment continues to be useful in predicting benefit for anti-EGFR treatment.

Uterine leiomyosarcoma is a rare malignant smooth muscle tumor originating in the uterine wall that generally responds poorly to chemotherapy and radiation.

We investigated the in vitro effects of a novel nutrient mixture containing lysine, proline, ascorbic acid, and green tea extract on the human leiomyosarcoma cell line SK-UT-1by measuring cell proliferation, invasiveness, apoptosis, and expression of matrix metalloproteinases (MMP). We also tested the effects of nutrient mixture in vivo using nude mice.

Human leiomyosarcoma SK-UT-1cells were treated with different concentrations of nutrient mixture. Cell proliferation was determined by MTT assay; MMP expression by gelatinase zymography; invasion by Matrigel assay; migration by scratch test; apoptosis using Live Green caspase kit. In vivo studies were conducted on 5-6weeks old female nude mice inoculated subcutaneously with 3• 10
SK-UT-1cells. The mice were fed a regular diet or a diet supplemented with 0.5% nutrient mixture. After four weeks, the mgest a therapeutic potential for nutrient mixture in uterine leiomyosarcoma treatment.

The state-of-the-art brachytherapy technologies with high-dose sources of
Co and
Ir within contemporary treatment protocols for cancer patients allow achieving maximum dose distribution in the clinical target and with minimum radiation exposure of surrounding organs and tissues. For minimization and overcoming the early and late radiation complications, development of respective radiobiological criteria along with perfecting of physical and technical characteristics of the ionizing radiation sources are required.

To study the effect of
Ir radiation on the chromosomal aberrations and prooxidant/antioxidant status of blood lymphocytes in gynecological cancer patients.

The patients (n= 45) with endometrial, cervical and secondary cancer of vagina were enrolled in the study. For brachytherapy, the irradiation of vaginal mucosa was conducted using "GammaMed plus" device for contact radiation therapy with
Ir source. click here Prior to irradiation and in 20-24h after brachytherapy session, the venous blood samplnd intensifies prooxidant processes in the blood.
Cellular heterogeneity is regarded as a major factor affecting treatment response and resistance in malignant melanoma. Recent developments in single-cell sequencing technology have provided deeper insights into these mechanisms.

Here, we analyzed a

-mutant melanoma cell line by single-cell RNA-seq under various conditions cells sensitive to BRAF inhibition with BRAF inhibitor vemurafenib and cells resistant to BRAF inhibition with vemurafenib alone or vemurafenib in combination with the MEK1/2 inhibitors cobimetinib or trametinib. Dimensionality reduction by t-distributed stochastic neighbor embedding and self-organizing maps identified distinct trajectories of resistance development clearly separating the 4 treatment conditions in cell and gene state space.

Trajectories associated with resistance to single-agent treatment involved cell cycle, extracellular matrix, and de-differentiation programs. In contrast, shifts detected in double-resistant cells primarily affected translation and mitogen-activated protein kinase pathway reactivation, with a small subpopulation showing markers of pluripotency.
