VASCULAR ENDOTHELIAL GROWTH FACTOR AND ENDOSTATIN IN BLOOD SERUM OF PATIENTS NON-SMALL-CELL LUNG CANCER IN RADIATION THERAPY
The purpose of the research is to study serum levels of VEGF and endostatin and VEGF/endostatin ratio in patients with NSCLC in radiation therapy (RT) over time.
Materials and methods. The study enrolled 16 patients with NSCLC of stage III. The patients underwent treatment at SI Grigoriev Institute for Medical Radiology of National Academy of Medical Science of Ukraine and completed a course of RT on the linear accelerator Clinac 600C. The patients with NSCLC were represented by 3 women and 13 men. The control group included 10 apparently healthy people. The general clinical, morphological and x-ray examination of all patients was carried out. The content of VEGF and endostatin in blood serum was determined by means of the method of enzyme multiplied immunoassay with the use of the standard Vektor-Best sets (Russia) before and after radiation therapy.
Outcomes. The study of serum levels of VEGF and endostatin and VEGF/endostatin ratio in patients with NSCLC in PT was conducted over time. It has been proved that in the course of radiation therapy the content of VEGF, endostatin and the ratio of VEGF/endostatin changes. It has been found that before treatment, in patients with NSCLC the angiogenic factor is produced more than antiangiogenic one. In other words, endostatin level increase is not proportional to the VEGF level increase; the balance is impaired. It leads to angiogenic cancer progression. After RT in patients with NSCLC, a non-uniform change in levels of VEGF, endostatin and VEGF/endostatin ratio depending on effectiveness of treatment is observed.
Conclusions. The level of VEGF, endostation and VEGF/endostatin ratio in patients were assessed in radiation therapy over time. It has been proved that the content of VEGF, endostatin and VEGF/endostatin ratio in blood serum in 94% of patients with NSCLC prior to RT is significantly higher than in the control group. The changes in the balance of angiogenic and antiangiogenic factors (VEGF/endostatin) in RT over time in patients with NSCLC associated with the objective response to treatment have established. It can a be predictive marker for evaluating the effectiveness of RT.
Keywords: radiotherapy, vascular endothelial growth factor (VEGF), endostatin, angiogenesis, non-small-cell lung cancer.

METHOD OF ENDOVASCULAR INHIBITION OF LOCALLY ADVANCED BREAST CANCER NEOVASCULARIZATION
Summary. Locally advanced breast cancer (LA BC) is one of the most hypervascular cancers of high angiogenic potential. It is identifiable by angiographic examination, which allows choosing the optimal ways of delivering cytostatics for targeted intraarterial chemotherapy.
Materials and methods. In order to maximize the locoregional effect on the neovascular network of LA BC targeted intra-arterial chemotherapy has been performed in 100 patients with cancer of II B stage diagnosed in 35, III B in 39 and IV stage in 26. In order to carry out targeted intra-arterial chemotherapy, the vessels of the tumor were catheterized from the basins of the internal thoracic, lateral thoracic, subscapular arteries. Carboplatin 300 mg/m2 or cisplatin 100 mg/m2, cyclophosphamide 600 mg/m2 have been infused. Infusion of cytostatics was carried out at a rate of 100 ml/h2. Doxorubicine was infused intravenously at a dose of 90 mg/m2.
Outcomes. Intensive extraction of cytostatic agents at the time of the first passage through the native vascular bed initiates an acute local disorder of vascular stability. Three sessions of selective intra-arterial chemotherapy is sufficient to overcome the resistance barrier of endothelial and tumor cells to chemical agents and to induce a state of oppression of tumor blood flow and tissue destruction. Anti-neovascular therapy of LS BC is aimed at the already formed tumor vessels and has the potential to destroy the already existing tumor mass.
Conclusions. A combined method of endovasular inhibition of neovascularization of the tumor has been developed to increase the loco-regional effect on the tumor vascular bed and the tumor tissue itself.
Keywords: locally advanced breast cancer, selective chemotherapy, inhibition of neovascularization, target chemotherapy, selective catheterization of tumor vessels.

METHODS OF NUCLEAR MEDICINE IN THE DIAGNOSIS OF PARA-ENDOPROSTHETIC COMPLICATIONS IN PATIENTS WITH DISEASE OF HIP AND KNEE JOINT OF VARIOUS GENESIS
Purpose. To study the role of nuclear medicine diagnostic methods in predicting implant-associated complications of patients with hip and knee joint damage of various genesis.
Materials and methods. Bone scintigraphy was carried out on a single-detector gamma camera Tamara 301-T in a static mode according to the standard protocol after intravenous administration of 99mTc-MDP activity of 600-800 MBq.
Outcomes. Significant increase in arterial inflow rates (p < 0.05) and integral perfusion with bone scintigraphy (p < 0.05) occurs in the area of hyperfixation of the radiopharmaceutical in infectious inflammatory processes due to intensification of osteoblastic activity and angiogenesis in them in comparison with the degenerative-dystrophic area of fixation of radiopharmaceutical.
In the differential diagnosis of pathological processes of the hip and knee joints, the bone scintigraphy has a greater sensitivity and accuracy (93.4 % and 88.6 %) than the method of X-ray (62,5 % and 65,8 %), ultrasound (80,7 % and 85,2 %), thermography (83,2 % and 74,3 %), respectively; However, CT and MRI methods have a high specificity (89,3 % and 92,1 %), with respect to the bone scintigrahy 83,3%), respectively.
Conclusions. Three-phase bone scintigraphy is an objective method of differential diagnosis of the pathological process in arthroplasty of hip and knee joints. This method can be used in diagnostic screening of patients during arthroplasty. Bone scintigraphy can be used to determine the stage of prevalence of the pathological process in the joints, and in combination with CT and MRI — to monitor the dynamics of the pathological process after arthroplasty.

ROLE OF INSULIN RESISTANCE AND HYPOTHYROIDISM IN PATHOGENESIS OF OBESITY IN ADOLESCENTS BORN OF PARENTS EXPOSED TO IONIZING RADIATION AFTER THE CHNPP ACCIDENT
The survey findings have shown that examination of 186 children aged from 12 to 17 who were born of parents evacuated out of 30km exclusion zone, citizens of the administered area, makes it possible to reveal increased risk of benign endocrine pathology (thyroid, impaired carbohydrates metabolism, obesity, hypothalamic syndrome) in adolescence with the signs of latent hormone dysfunction.
In every other adolescent there is an interaction between impaired function of the thyroid gland (hypothyroidism) and present insulinemia and insulin resistance resulting in disturbance of fat metabolism. Progressing of overweight in adolescence is accompanied by significant metabolic disorders which can be a trigger in development of MSX. Resistance to insulin as well as peripheral resistance to thyroid hormones lead to metabolic disorders, one of which is obesity. Hormone disfunction, which result in impaired of carbohydrate and fat metabolism, can be a predictive criterion of development of diabetes mellitus of type II in future.
Keywords: adolescents, ChNPP accident, insulin resistance, hypothyroidism, obesity.

RADIOLOGICAL CONSEQUENCES OF POSSIBLE IRRADIATION SCENARIOS IN MILITARY PRACTICE IN UKRAINE
Objectives. To classify the main radiological consequences (health effects) of radiation exposure that lead to the loss of the work efficiency of the personnel of the Armed Forces of Ukraine in various scenarios of radiation exposure, which are expected in modern military practice.
Materials and Methods. The information search was carried out in the normative documents of the military radiation safety system and military radiology manuals. Possible scenarios of radiation exposure of military units during war time were modeled according to the modern paradigm of the usage of nuclear weapons. The genuine information was analysed and synthesized regarding early radiobiological effects of radiation exposure in humans in those conditions, which correspond to the military exposure scenarios.
Results. For the first time the logical and handy classification of possible radiation exposure scenarios in military practice is presented. It combines the causal situation, the type of battle task and early clinical effects, which lead to the reduction of the work efficiency of the personnel. Five causal situations are distinguished; each containing from one to three variants of the contact with ionizing radiation; and for each particular scenario the specific syptoms of early biomedical effects of the external and/or internal irradiation are presented. The assessment of the work efficacy of military units has to be based of the criteria of the grade and frequency distribution of the general primary reaction on the irradiation. The consequences of radiation exposure are listed in the ascending order of their health danger: from the radiophobia up to the toxemic or cerebral forms of acute radiation syndrome, early transitive disability syndrome and combined radiation-traumatic or radiation-termal injuries.
Conclusions. The clinical consequences of radiation exposure, which determine the loss of work efficiency of military subdivisions, vary essentially depending on the scenario of irradiation. The underestimation of the full possible spectrum of radiological effects beyond the acute radiation syndrome may lead to the mistakes in the evaluation of the personnel losses during the war time. Further optimization of the military radiation safety system requires the establishing of clear quantitative coeffecients linking various clinical radiation symptoms and the losses of work efficiency in exposed military units.
Keywords: military scenarios of radiation exposure, acute radiation syndrome, local radiation injuries, oropharingeal syndrome, radiophobia, loss of work efficiency of military personnel.

RADIONUCLIDE THERAPY OF BONE METASTASES IN COMBINATION WITH SURGICAL TREATMENT, CHEMOTHERAPY AND BISPHOSPHONATES
The review is devoted to the palliative treatment of metastatic lesions of the bone system of cancer patients using radionuclide therapy (RNT) in combination with the methods of surgical and chemotherapeutic treatment, as well as the using of bisphosphonates. The article show a broad approach to this problem. The authors analyze the advantages and disadvantages of combining these therapies based on the literature data. It is shown that the surgical treatment, administration of chemotherapy and bisphosphonates can potentially improve the effect of subsequent RNT, however, the possibility of postoperative complications and the toxic effect of chemotherapy should be taken into account. In view of the foregoing, it is necessary to conduct individual planning of combined therapy depending on the condition of internal organs and the hemopoiesis system.
