The influence of the stage of the disease and degree of the tumor regression at radiation therapy on survival of the patients with inoperable epidermoid lung cancer
Summary. Main prerequisite of relatively high quality parameters of survival at radiation therapy for epidermoid lung cancer is complete tumor regression. One-year oncospecific survival of patients with stages I+II at complete tumor regression makes 86.4 ±4.2 %, with stage III — 86.3 ± 4.8 %; when compete effect was not achieved — 49.8 ± 3.9 % and 43.5 ± 4.1 %, respectively. Three-year survival of the patients with stages I+II at complete regression makes 40.2 ± 6.1 %, with stage III — 37.4 ± 6.9 % ; when compete effect was not achieved — 9.3 ± 2.3 % and 4.5 ± 1.9 %, respectively. Five year survival of the patients with stages I + II at complete regression makes — 19.7 ± 5.2%, with stage III — 13.3 ± 5.2 %; when compete effect was not achieved — 6.6 ± 2.1 % and 0.0 + 0.6 %, respectively.
Key words: lung cancer, radiation therapy, disease stage, tumor regression, survival.

Tumor marker CYFRA 21-1 in assessment of radiation treatment efficacy at local non-small-cell lung cancer
Summary. The results of radiation therapy (RT) at various fractionation modes with Etopiside and Cysplatin modification in patients with non-small-cell lung cancer (NSCLC) are ana- lyzed. The objective effect of accelerated RT was accompanied by statistically significant reduction of blood serum CYFRA 21-1 level (an index of proteolytic tumor degradation). It was established that the dynamics of blood serum CYFRA 21-1 expression coincided with the clinical findings and could be used for prognosis and monitoring of chemoradiation therapy efficacy in patients with NSCLC.
Key words: non-small-cell lung cancer, radiation therapy, accelerated fractionation modes, objective effect, CYFRA 21-1 expression.

Radiation therapy for operable rectal cancer
Summary. The authors present a review of the literature on modern tendencies of radiation therapy application to treatment of operable rectal cancer. Many randomized control studies compared the efficacy of combination of radiation therapy (pre-operative or post-operative) and surgery versus surgery only demonstrating various results. Meta-analysis of the data on efficacy of combination of radiation therapy and standard surgery revealed 22 randomized control studies (14 with pre-operative radiation therapy and 8 with post-operative radiation therapy) with total number of 8507 patients (Colorectal Cancer Collaborative Group, 2000). The use of combination treatment reduced the number of isolated locoregional relapses both with pre-operative (22.5 - 12.5 %; p < 0.00001) and post-operative radiation therapy (25.8 - 16.7 %; p - 0.00001). The influence on total survival was not significant (62 % vs. 63 %; p - 0.06).

Approaches to chemoradiation therapy of patients with relapses and metastases of brain cancer
Summary. A possibility and efficacy of chemoradiation therapy (CRT) in patients with relapses and metastases of breast cancer (BC) with the history of radical treatment (combination or chemoradiation therapy with hormone therapy) for local BC is shown. The treatment was differentiated depending of the disease localization. The patients with local relapses in the area of the breast were administered distance radiation therapy (DRT) and 4 courses of polychemotherapy (PCT) by TC protocol (Neotaxel 175 mg/m2 + Carboplatin 250-300 mg/ m2). The patients with metastases to the brain were administered Temodal in radiomodifying dose of 75 mg/m2 per day during the course of DRT to the neurocranium, after 4 week break the patients were administered 6 courses of Temozolomide as monotherapy by the standard protocol. The patients with metastases to the skeleton were administered DRT with bisphonoites administration. The described techniques of CRT for relapses and metastases of breast cancer are moderately toxic and demonstate a favorable profile of safety, which positively influences the quality of life of these patients.

Complex application of CT and ultrasonography in diagnosis of secondary liver lesions
Summary. Efficacy of complex application of CT and ultrasonography in diagnosis of secondary liver lesions was assessed. It was established that only complex application of computed tomography with contrast enhancement and ultrasonography can give complete information for diagnosis of secondary liver lesions. Diagnostic value of CT without contrast enhancement is very low while radiation load to the patients is unreasonably high.
Key words: computed tomography, ultrasound investigations, secondary liver lesions.

A technique of calculation of very low-frequency electromagnetic radiation doses at treatment of radiation lesions
Summary. A technique of calculation of effective tissue doses of very-low frequency electromagnetic radiation at treatment of patients with late radiation lesions with increased and decreased functional activity of the tissue in the lesion focus allowing determining irradiation mode was suggested.
Key words: dosimetry, very-low frequency electromagnetic radiation.

Prognostic significance of intercellular adhesion markers expression in patients with cancer of oropharynx
Summary. The level of expression of intercellular adhesion markers (E-cadherin and β-catenin) in patients with squamous cell cancer of the oropharynx was performed with the purpose to reveal clinical morphological associations and analyze their significance for the efficacy of chemoradiation therapy. Prognostic significance of each marker as to the effect of radiation therapy was established.
Key words: cancer of oropharynx, E-cadhegin, β-catenin.

The analysis of combination treatment for gastric cancer depending on the tumor location
Summary. The results of combination treatment for gastric cancer are reported depending on the tumor location. Radiation therapy in the mode of medium fractionation was well tolerated. Increased doses up to 54-56 Gy allowed to improve long-term results and did not cause delay in surgery. The most prognostically favorable location is lower portion of the stomach.
Key words: gastric cancer, combination treatment, radiation therapy.

Clinical peculiarities of the course of early and late postchemioradiation pulmonary lesions in patients with breast cancer
Summary. The paper features the investigation of pulmonary complications after chemoradiation therapy in patients with breast cancer. It was found that respiratory system lesions developed in 76.7 % of patients. Early lesions, mainly bronchitis and pulmonitis, developed 3 months after the beginning of treatment in 63.4 % of patients, were accompanied by dyspnea, cough, inflammatory phenomena, reduction of oxygen saturation and external respiratory parameters. After 6 months inflammatory phenomena subsided, the function of breathing restored. After 12 months SCT demonstrated pneumosclerosis and fibrosis in 33 % of patients, they were accompanied by a significant reduction of external respiration (forced capacity, maximum lung ventilation, peak expiratory volumetric rate and oxygen saturation) and secondary inflammation. Clinical manifestations of late postchemoradiation complications do not always correspond to x-ray images; therefore SCT plays an important role in early diagnosis of pneumosclerosis and pneumofibrosis.
Key words: breast cancer, chemoradiation therapy, pulmonary lesions.

First clinical achievements of Rivne Center for Radiation Therapy at application of a linear accelerator
Summary. The authors report the results of the use of 3D-conforinal therapy using a linear accelerator at Rivne Regional Cancer Hospital. Examples of treatment of definite cases are given. The necessity to use fixation appliance as well as replacement of radiotherapy equipment in Ukraine is shown.
Key words: 3D-conformal radiation therapy, equipment, examination, capabilities, dynamics, result.
