Abstract
It perdormed the literature data analysis on the criteria and methods for assessing the clinical efficacy of the isolated limb perfusion method in the treatment of soft tissue sarcoma. It is noted that the use of isolated limb perfusion is a rather effective method providing local control of the tumor process in locally advanced forms of soft tissue sarcoma. It has been demonstrated that the use of such a neoadjuvant treatment regimen allows administration of the drug with the achievement of high local concentrations of chemotherapeutic drugs with a relatively low incidence of systemic side effects. Criteria for tumor response to therapy, in particular RECIST (Response Evaluation Criteria In Solid Tumors), Choi criteria, adapted for magnetic resonance imaging, are presented. It is noted that a number of studies have studied the possibility of using positron emission tomography with fluorodeoxyglucose labeled with 18F (18F-FDG) to assess the response to treatment in sarcomas. At the same time, it was shown that the results of studying the metabolic response are superior in accuracy to the method of assessment using the RECIST criteria and the assessment performed by the dynamics of the tumor tissue volume has significant potential in assessing the response to isolated limb perfusion in patients with soft tissue sarcoma. The importance of a one-time assessment of positron emission tomography with 18F-FDG parameters and Magnetic Resonance Imaging for soft tissue sarcoma is confirmed by the results of a combined analysis that takes into account both morphological characteristics and quantitative metabolic parameters of the tumor. The high potential of the combined assessment of metabolic and volume-morphological parameters obtained using these methods was demonstrated; it was noted that the combination of positron emission tomography data with 18F-FDG and Magnetic Resonance Imaging enhances the reliability and efficiency of planning and monitoring of soft tissue sarcoma treatment using the isolated limb perfusion method.

Summary
Что критерии, которые основываются исключительно на размерах новообразования, не являются достаточными для корректной оценки ответа на неоадъювантную терапию СМТ [21, 22]. В дополнение к различным критериям ответа на терапию, основанным на размерах и морфологических характеристиках новообразования, в нескольких исследованиях были оценены возможность и эффективность использования позитронно-эмиссионной томографии (ПЭТ) с фтордезоксиглюкозой, меченной 18F (18F-ФДГ), для оценки ответа на лечение при саркомах [26].
