Фотодинамическая терапия в хирургическом лечении больных меланомой кожи

In experimental and clinical research carried out studying of influence of neoadjyuvant photodynamic therapy on T- and B-cellular immune answer in surgical treatment of patients of a melanoma of skin of the I–III stage. PDT was executed to 25 patients two days prior to surgical removal of primary tumor from July, 2012 to January, 2013. As a result of the conducted research it was revealed that: the increase in concentration fotoditaziny doesn‘t lead to increase in quantity of tumoral cages at stages early apoptosis; lengthening of time of an exposition leads to increase in a share of late forms apoptosis, and FDT use with fotoditaziny in a dose of 50,0 mg with the subsequent radiation (662 nanometers, 400 J) in 2 days prior to surgical intervention promotes T- and B-cellular link of immune system.В экспериментально-клиническом исследовании изучено влияние неоадъювантной фотодинамической терапии на показатели Т- и В-клеточного иммунного ответа в хирургическом лечении больных меланомой кожи I–III стадии. ФДТ была выполнена 25 пациентам за 2 сут до хирургического удаления первичной опухоли с июля 2012 г. по январь 2013 г. Выявлено, что увеличение концентрации фотодитазина не приводит к увеличению количества опухолевых клеток на стадии раннего апоптоза; удлинение времени экспозиции приводит к увеличению доли поздних форм апоптоза, а использование ФДТ с фотодитазином в дозе 50,0 мг с последующим облучением (662 нм, 400 Дж) за 2 дня до хирургического вмешательства способствует активации Т- и В-клеточного звена иммунной систем
