The cytogenetic damage in gynaecological cancer patients during radiotherapy. I. The variability of cytogenetic response to irradiation
Objectives: To evaluate the limits of cytogenetic changes in blood lymphocytes of gynecological cancer patients undergoing radiotherapy and to assess the individual variability of the kinetics of chromosome aberration yields depending on treatment schemes.
Materials and methods: Cytogenetic study was carried out in 53 female patients with uterine cancer (UCa), 5 cervical cancer patients (CCa) and 12 ovarian cancer patients (OCa), who underwent standard cources of telegammatherapy (TGT, 38 persons), intracavitary brachytherapy (ICBT, 10 persons) or a combination of both (CRT, 22 persons). Conventional cytogenetic analysis aimed at recording chromosomal aberrations and genomic abnormalities, was performed in 50-h lymphocyte cultures, set up from samples collected before irradiation and throughout the radiotherapy (RT) course; in total 186 individual examinations was done. For each patient the individual rate of accumulation of unstable chromosome type aberration yield (ACsunst) was calculated in terms of a regression "the number of RT fractions - effect"; the variation coefficient for this parameter was estimated inside the groups. The changes in the average kinetics of cytogenetic effects throughout the RT course were analyzed.
Results: Any studied RT scheme produced a significant elevation of cytogenetic damage yield in patients' lymphocytes that occurred nearly exclusively due to accumulation of ACsunst. The ranges of individual aberration yields were essentially overlapped in TGT and CRT groups, and in both groups markedly exceeded the respective parameters in ICBT group. The individual rates of the ACsunst accumulation varied from 2 to 23 times between persons of the same RT group studied at similar treatment stage. Among 32 patients, who were followed up individually in the middle and the end of the RT course, there were 13 cases of the linear increase of the ACsunst yield, 4 cases of acceleration of the kinetics from the middle to the end of the RT course and 15 cases of plateauing or decrease of aberration yield in the second part of RT. The variation coefficient for the accumulation rate of the ACsunst ranged from 50 to 80 % at different stages of RT; the average value for the studied cohort was about 70 %. This parameter increased throughout the RT course in all groups independently on the RT scheme.
Conclusions: For the first time in vivo aberration yields were compared in the representational groups of gynecological cancer patients undergoing telegammatherapy, intracavital brachytherapy or their combination; the limits of cytogenetic changes were evaluated and the magnitude of the individual variability of kinetics of cytogenetic damage yield was assessed depending on the scheme of therapeutic irradiation. These data are basic for the appraisal of the prognostic value of cytogenetic damage as clinically-meaningful markers during RT.
Key words: chromosome aberrations, radiotherapy, uterine cancer, ovarian cancer.

Influence of clinical characteristics on radiation therapy effect in patients with stage III non-small-cell lung cancer at non-standard fractionation modes
Summary. A comparative analysis of different modes of radiotherapy fractionation with modification using etoposide and cisplatin in patients with non-small-cell lung cancer is given. Objective response was significantly higher in the accelerated fractionation modes, while the frequency of positive response depended on the general condition of the patient, the extent of the tumor process, morphology, growth form.

The experience of conformal radiotherapy of locally advanced forms of cervical cancer
Summary. The Department of Radiation Oncology, National Cancer Institute, studies optimization of combined radiation therapy (CRT) for locally advanced cancers of the cervix (LACC). CRT was performed in 70 patients with stage IIB IIIB (T2b-3bN0-1M0) cervical cancer aged 29-70. Effective methods of complex conservative treatment of patients with LACC were worked out. Then the system of choosing the best mode of carrying out with the help of mathematical modeling, the correct, individual planning, precise implementation of the planned program of irradiation was used. To prevent toxic effects increase through the use of high-energy gamma-therapy units, a compbing of preventive megures, including drug presentia was taken. Toxic effects of treatment on their number and degree of symptoms between groups of patients did not exceed the second degree. The immediate results of CRT indicate that statistically significant differences in the response of the tumor and the reactions of the critical organs in patients of the groups who received brachytherapy for high-energy setting (HDR BT) by developing a method in comparison with the control was observed. However, there is a clear tendency to increase the regression group II patients with relatively radioresistant forms of LACC who underwent conformal external beam radiotherapy up to a total of 45 - 50 Gy followed by HDR BT single focal dose of 7 Gy, which is the result of amplification of the destructive effects of ionizing radiation on the high voltage tumor target.

Narrow beam dosimetry
Summary. Application of new methods of the dose delivery such as IMRT ^intensity modulation radiation therapy), IGRT (image-guided radiation therapy), SRS (stereotaxic radiosurgery) require the use of beams less than 3 x 3 cm2. Such beams are termed narrow and require special attention when performing dosimetry and dose calculation, because this can cause to considerable over-irradiation of the patients. Literature analysis and our measurements demonstrated that optimal detectors for supporting dosimetry of narrow beams were diode detectors.

The peculiarities of bone mineral density disorders in patients with local prostate cancer depending on hormone therapy protocol
Summary. The influence of various protocols of androgen-suppressive therapy on bone mineral density as well as influence on mineral metabolism in the bones of nonsteroid androgens (bicalutamide) in patients with prostate cancer were compared using x-ray osteodensitometry.
Key words: prostate cancer, osteopenia, osteoporosis, osteodensitometry, bicalutamid, diferelin, bilateral orchidectomy.

Pharmacotherapy for relapses and metastases of cervical cancer: from fluorpyrimidines to target drugs
Summary. Nineteen percent of Ukrainian patients with cervical cancer present with generalized stages of the disease. Dissemination and progression of the process occur in 40-50% of the patients, 16% do not survive over a year after the diagnosis has been made. Administration of Topotecan, Gemzar, taxanes separately and by the protocols as well as in combination with target drugs allows to prolong the life span and improve its quality in this group of the patients.
Key words: relapsing and disseminated cervical cancer, pharmacotherapy.

Monte Carlo calculation of backscatter factor for monoenergetic x-rays
Summary. Backscatter factors were calculated for mono-energetic x-rays (10-300 kev). Their dependence on the energy, field size, and thickness of the irradiated material was determined. Dose-depth distribution was established; analytical dependence of the dose on the target depth was revealed.
Key words: Monte Carlo simulation, backscatter factor, x-rays.
We are proud to announce the annual scientific conference of young scientists with the international participation, dedicated to the Day of Science in Ukraine. The conference will be held on 20th of May, 2016 and hosted by L.T. Malaya National Therapy Institute, NAMS of Ukraine together with Grigoriev Institute for medical Radiology, NAMS of Ukraine. The leading topic of conference is prophylaxis of the non-infectious disease in different branched of medicine.
Since 1993 the Institute became the founder and publisher of "Ukrainian Journal of Radiology”:
