Кросс-поляризационная ОКТ в оценке динамики состояния патологических и нормальных тканей при проведении лучевой и фотодинамической терапии

Abstract

The aim of the investigation was evaluating the possibilities of cross-polarization optical coherence tomography (CP OCT) to monitor the effectiveness of photodynamic therapy (PDT) and radiation therapy (RT) of the oral cancer and of the cervical cancer. Materials and Methods. The CP OCT investigation was performed by an OCT-1300U tomograph (Institute of Applied Physics of the Russian Academy of Sciences, LLC “Biomedtech”, Russia). The monitoring of the two types of treatment was performed after different periods of exposure: for RT of the oral cancer — once for every 2–3 days throughout the whole course of the treatment, starting from the first day of radiation; for the PDT of the cancers of the skin and cervix uteri — before the exposure, immediately after the exposure, and then at 1 day, 7 day and 1 month after the exposure. Fourteen patients were examined in total. Results. The results of the study of the medical pathomorphism of different kinds of tumors performed on the 14 patients showed that visual evaluation of CP OCT images of a tumor does not reveal any visible changes in response to RT, however it does register the reaction of the normal mucosa in the area exposed to the radiation. During the PDT of tumors of the skin and cervix mucosa CP OCT was capable of detecting the key morphological changes (edema, necrosis, and structural recovery). It can be applied most effectively at later stages of the follow-up observation (at 30–35 days after PDT) to evaluate the completeness of the recovery of the stromal component of the tissues. Conclusion. The use of CP OCT contributes to realization of non-invasive monitoring of the responses of tumors and the adjacent normal tissues to PDT and to RT that can be useful for evaluation of the effectiveness of therapy and to help in choosing optimal tactics for the treatment.

Цель исследования — оценить возможности применения кросс-поляризационной оптической когерентной томографии (КП ОКТ) для мониторинга эффективности лечения рака полости рта, кожи и шейки матки после фотодинамической (ФДТ) и лучевой терапии (ЛТ). Материалы и методы. КП ОКТ-исследование выполняли с использованием установки «ОКТ-1300У» (ИПФ РАН, ООО «Биомедтех», Россия). Мониторинг двух видов лечения проводили на разных сроках воздействия: при ЛТ рака полости рта — один раз в 2–3 дня на протяжении всего курса лечения, начиная с первого дня облучения; при ФДТ рака кожи и шейки матки — до воздействия, непосредственно после воздействия, через 1 сут, 7 сут и 1 мес после воздействия. Всего обследовано 14 пациентов. Результаты. Данные изучения лечебного патоморфоза разного вида опухолей, проведенного у 14 пациентов, показали, что визуальная оценка КП ОКТ-изображений опухоли не выявляет видимых изменений в ответ на ЛТ, однако обнаруживает реакцию нормальной слизистой оболочки, попавшей в зону облучения. В ходе ФДТ опухолей кожи и слизистой оболочки шейки матки (отек, некроз, восстановление структуры) КП ОКТ способна детектировать ключевые морфологические изменения. Наиболее эффективно она может быть использована на поздних сроках наблюдения (через 30–35 дней после ФДТ) для оценки полноценности восстановления стромального компонента тканей. Заключение. Применение КП ОКТ способствует реализации неинвазивного мониторинга ответа опухоли и прилежащих нормальных тканей на проведение ФДТ и ЛТ, что может быть полезным для оценки эффективности терапии с целью выбора оптимальной тактики лечения.
