Radiation therapy is one of the main treatments for locally advanced cancers of the rectum, cervix, and prostate. As a result of summing up high total doses, radiation damage occurs in patients.</p><p><bold>Aim</bold>. To determine the frequency of late radiation injuries in patients, their impact on overall survival and quality of life.</p><p><bold>Materials and methods</bold>. The study included 759 patients who received treatment in medical facilities in St. Petersburg and the Leningrad Region, of which 324 were men and 435 were women aged 27–88 years, with a diagnosis of rectal cancer – 257, cervical cancer – 327, prostate cancer – 175 patients. Irradiation was carried out on linear accelerators and brachytherapy devices. The quality of life of patients was assessed by questionnaires based on QLQ-30.</p><p><bold>Results</bold>. The overall toxicity was 35.01 % in patients with cervical cancer, 10.4 % in patients with rectal cancer and 7.6 % in patients with prostate cancer. Overall long-term 5 and 10 years survival in patients with late complications was 46.3 and 16.5 % <italic>versus</italic> 66.5 and 33.4 % in patients without late complications (<italic>p</italic> = 0.001). In patients diagnosed with rectal cancer, it was significantly higher than in other groups (<italic>p</italic> &lt;0.05). 3–5 weeks after the end of radiation therapy, patients reported a significant deterioration in the quality of life.</p><p><bold>Conclusion</bold>. Late radiation damage is an important prognostic factor influencing long-term survival in patients diagnosed with cancer of the rectum, cervix and prostate. A decrease in the quality of life in patients who received irradiation of the pelvic organs 3–5 weeks after the end of radiation therapy has been proven.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение</bold>. Лучевая терапия – один из основных способов лечения местно-распространенного рака прямой кишки, шейки матки и предстательной железы. Вследствие подведения высоких суммарных доз у пациентов возникают лучевые повреждения.</p><p><bold>Цель исследования</bold> – определение частоты поздних лучевых повреждений, их влияния на общую выживаемость и качество жизни больных.</p><p><bold>Материалы и методы</bold>. В исследование были включены 759 больных в возрасте 27–88 лет (324 мужчины и 435 женщин), получавших лечение в лечебных учреждениях Санкт-Петербурга и Ленинградской области; из них с диагнозом рака прямой кишки – 257 человек, рака шейки матки – 327, рака предстательной железы – 175. Облучение проводилось на линейных ускорителях и брахитерапевтических аппаратах. Качество жизни пациентов оценивали по опросным листам на основе опросного листа QLQ-30.</p><p><bold>Результаты</bold>. По результатам исследования, общая токсичность составила 35,01 % у больных раком шейки матки, 10,4 % у больных раком прямой кишки и 7,6 % у больных раком предстательной железы. Общая 5- и 10-летняя выживаемость у пациентов с поздними осложнениями составила соответственно 46,3 и 16,5 % против 66,5 и 33,4 % у пациентов без поздних осложнений (<italic>р</italic> = 0,001). У пациентов с диагнозом рака прямой кишки качество жизни было достоверно выше, чем в других группах (<italic>р</italic> &lt;0,05). Через 3–5 нед после окончания лучевой терапии больные сообщали о существенном ухудшении качества жизни.</p><p><bold>Заключение</bold>. Поздние лучевые повреждения являются важным прогностическим фактором, влияющим на отдаленную выживаемость больных с диагнозами рака прямой кишки, шейки матки и предстательной железы. Доказано снижение качества жизни у пациентов, получавших облучение органов малого таза, через 3–5 нед после окончания лучевой терапии.</p></trans-abstract><kwd-group xml:lang="en"><kwd>radiation therapy</kwd><kwd>late complications of radiation therapy</kwd><kwd>rectal cancer</kwd><kwd>cervical cancer</kwd><kwd>prostate cancer</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>лучевая терапия</kwd><kwd>поздние лучевые осложнения</kwd><kwd>рак прямой кишки</kwd><kwd>рак шейки матки</kwd><kwd>рак предстательной железы</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">State of oncological care to the population of Russia in 2019.
