Androgen deprivation was used in 73.5% of patients for 6 to 12 months.Results: The patients with a baseline pros tate-specific antigen level &lt; 20 ng/ml had the highest 5-year survival rate of 86%. There was no significant difference in a 5-year survival that depending on a total focal dose (&lt; 64 Gr; ≥ 64 Gr) of DGT if used in combination with androgen deprivation. Conclusion: This data represents only the first step in establishment of the criteria to choose the type of DGT in prostate cancer patients. The optimization of a treatment strategy based on a thorough analysis of data, including that on comorbidities and their severity, would make the use of DGT more rational that will reduce costs of treatment.</p></abstract><trans-abstract xml:lang="ru"><p>Актуальность. Основанием для применения дистанционной гамма-терапии (ДГТ) у пациентов с раком предстательной железы послужили данные об ее эффективности в сочетании с современными планирующими устройствами и более низкая себестоимость по сравнению с использованием линейного медицинского ускорителя.Цель – оценить влияние применения ДГТ у пациентов с раком предстательной железы с использованием компьютерной программы 3D-планирования Амфора на показатель 5-летней выживаемости в зависимости от основных прогностических критериев эффективности лечения. Материал и методы. В исследование включены 34 пациента с раком предстательной железы, которые получили низкодозную ДГТ в суммарной очаговой дозе 62–70 Гр. Андрогенная депривация имела место у 73,5% пациентов в течение 6–12 месяцев. Результаты. У пациентов с исходным уровнем простатспецифического антигена в крови &lt; 20 нг/мл показатель 5-летней выживае мости оказался наивысшим и составил 86%. Установлено, что в условиях сочетанного применения с андрогенной депривацией суммарная очаговая доза при низкодозной ДГТ (&lt; 64 Гр; ≥ 64 Гр) не оказывает статистически значимого влияния на показатель 5-летней выживаемости (p = 0,61). Заключение. Полученные нами результаты – лишь первый шаг на пути установления критериев, позволяющих выбрать способ дистанционной лучевой терапии при раке предстательной железы. Оптимизация определения тактики лечения на основании тщательного анализа исходных данных, в том числе о степени тяжести сопутствующей патологии, сделает использование ДГТ более обоснованным, что будет способствовать снижению себестоимости лечения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>prostate cancer</kwd><kwd>radiation therapy</kwd><kwd>5-year survival</kwd><kwd>costs of radiation therapy</kwd><kwd>prostate-specific antigen</kwd><kwd>elderly</kwd><kwd>comorbidity</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рак предстательной железы</kwd><kwd>лучевая терапия</kwd><kwd>5-летняя выживаемость</kwd><kwd>себестоимость лучевой терапии</kwd><kwd>простатспецифический антиген</kwd><kwd>старческий возраст</kwd><kwd>сопутствующая патология</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
