В качестве одного из нефармакологических методов его профилактики и лечения используется низкоэнергетическое лазерное излучение (НИЛИ). Целью исследования было изучение эффективности НИЛИ красного диапазона для профилактики и лечения мукозита слизистой оболочки полости рта и глотки. Материалы и методы. В протокол включены 48 пациентов, получавших лучевую/химиолучевую терапию по поводу злокачественных новообразований полости рта, ротоглотки и носоглотки, которые случайным образом были разделены на две группы. В первой группе (28 пациентов) проводилась коррекция осложнений химиолучевого лечения в соответствии со стандартами клиники. Во второй группе (20 пациентов) дополнительно использовалось воздействие на слизистую оболочку низкоинтенсивным лазерным излучением (длина волны 635 нм, мощность 5 мВт) 3 раза в нед в течение 3 мин перед сеансом облучения, начиная с первого дня лечения. Результаты. В группе воздействия НИЛИ отмечалось статистически значимое снижение частоты и тяжести мукозита, а также снижение выраженности болевого синдрома по сравнению с группой стандартной коррекции мукозита. Статистически значимых различий по критерию появления первых симптомов побочных эффектов и по критерию продолжительности мукозита наиболее тяжелой степени выявлено не было. НИЛИ является эффективным и доступным методом, позволяющим существенно снизить частоту и тяжесть побочных эффектов лучевой и химиолучевой терапии.</p><p> </p></abstract><trans-abstract xml:lang="en"><p>Oral mucositis is the most common and significant complication of chemoradiation therapy for oral and pharyngeal cancer. There are no standard methods for preventing and treating this disease. Patients with severe adverse events need expensive supportive care and unplanned treatment breaks. The objective of the study was to assess and optimize the effectiveness of low level laser therapy (LLLT) for prevention and treatment of chemoradiation-induced oral mucositis in patients with oral and pharyngeal cancer. Material and Methods. Forty-eight patients who received chemoradiation therapy for oral and pharyngeal cancer were enrolled. All patients were randomly divided into two groups. Group I patients (n=28) received standard treatment of chemoradiation-induced complications. Group II patients (n=20) were treated with low level laser therapy (LLLT) at a wavelength of 635 nm, three times a week for three minutes prior to radiation therapy session. Results. In the LLLT group, a statistically significant decrease in the frequency and severity of oral mucositis as well as decrease in pain were observed as compared to the group with standard treatment (χ2 =64,14, р&lt;0,0001). No significant difference in the onset of symptoms and duration of severe mucositis were found. LLLT is an effective method capable of decreasing the frequency and severity of adverse events associated with concurrent chemoradiation therapy. Key words: radiation-induced mucositis, oral and pharyngeal cancer, low level laser therapy, chemoradiation therapy.&gt;&lt;0,0001). No significant difference in the onset of symptoms and duration of severe mucositis were found. LLLT is an effective method capable of decreasing the frequency and severity of adverse events associated with concurrent chemoradiation therapy.</p><p> </p></trans-abstract><kwd-group xml:lang="ru"><kwd>мукозит слизистой оболочки полости рта и глотки</kwd><kwd>рак полости рта и глотки</kwd><kwd>низкоинтенсивное лазерное излучение</kwd><kwd>лучевая/химиолучевая терапия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>radiation-induced mucositis</kwd><kwd>oral and pharyngeal cancer</kwd><kwd>low level laser therapy</kwd><kwd>chemoradiation therapy</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Пачес А.И.
