Диапазон возможностей и пределы метода ПЭТ-КТ с 18F-ФДГ в этом вопросе недостаточно изучены.</p><sec><title>Цель исследования</title><p>Цель исследования: определение диагностической значимости и места 18F-ФДГ ПЭТ-КТ в алгоритмах дифференциальной диагностики локорегионарного рецидива и постлучевых изменений в ранее облученных зонах у больных РШМ и РТМ.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Изучены данные динамического наблюдения, включая протоколы мультипараметрической МРТ (T1,T2ВИ, ДВИ, ДКУ) и 18F-ФДГ ПЭТ-КТ, за 51 больной РШМ (25 (49%)) и РТМ (26 (51%)) Ia–IIIc стадий, с подозрением на локорегионарный рецидив в зоне предшествовавшего облучения, через 4–96 мес после окончания лечения. Адъювантная сочетанная лучевая терапия (конформное дистанционное облучение таза – 3D-CRT, IMRT, VMAT, эндовагинальная 192Ir HDR брахитерапия) проведена 33 (64,7%) оперированным больным с химиорадиомодификацией Цисплатином 40 мг/м2 или Карбоплатином AUC2 еженедельно у 8 (24,2%) из них 18 (35,3%) больных РШМ получили курс радикального химиолучевого лечения, СОДэкв в области первичного очага (HR-CTV D90) 81,6 ± 4,4 Гр (CI 95% 72,4–93,7 Гр), в области метастатических лимфатических узлов – 54,6 ± 3,3 Гр (CI 95% 48,8–64,2 Гр).</p><p>Направление на 18F-ФДГ ПЭТ-КТ (Biograph True 64, Siemens, 3,8–4,7 MБк/кг, суммарно 169–356 MБк) явилось следствием сомнительных данных клинического, цитологического обследования, комплексного ультразвукового исследования и мультипараметрической МРТ. Любые зоны патологического захвата 18F-ФДГ ПЭТ-КТ расценивались как позитивные в отношении рецидива онкологического заболевания.</p></sec><sec><title>Результаты</title><p>Результаты. Отсутствие данных о прогрессировании в зоне предшествовавшего облучения было подтверждено у 32 (62,7%) больных анализируемой группы. Клинико-морфологические и радиологические признаки прогрессирования были получены у 16 (31,3%) больных c положительными находками на ПЭТ-КТ, SUVmax 2,86 – 8,8 в очагах патологической гиперфиксации. Ложноположительными оказались результаты ПЭТ-КТ с 18F-ФДГ у 6 (11,8%) больных, ложноотрицательным – у 1 (1,9%) больной РШМ. Чувствительность составила 94,1%, специфичность – 84,2%, положительная прогностическая значимость – 72,7%, отрицательная прогностическая значимость – 96,9%.</p></sec><sec><title>Заключение</title><p>Заключение. 18F-ФДГ-ПЭТ-КТ обладает высокой диагностической ценностью в дифференциальной диагностике рецидивов и постлучевых изменений в ранее облученных зонах у больных РШМ и РТМ. Трактовка данных требует междисциплинарного консилиума.</p></sec></abstract><trans-abstract xml:lang="en"><p>Early detection of cervical (CC) and endometrial (EC) cancer recurrence in previously irradiated areas remains a difficult task for clinicians and radiologists. 18F-FDG PET-CT scope and limits in this matter are not clear yet.</p><sec><title>Purpose</title><p>Purpose. To determine 18F-FDG PET-CT significance and diagnostic value in differential diagnosis of locoregional recurrence and post-radiation tissue changes in CC and EC patients with suspected relapse in preirradiated zones.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Follow-up data, including multiparametric MRI (T1-WI, T2-WI, DWI, DCE) and 18FFDG PET-CT full descriptions, were studied in 51pts., in 25(49%) CC and 26 (51%) EC Ia–IIIc FIGO, with suspected loco-regional recurrence in pre-irradiated area, 4–96 months after the end of treatment.</p><p>Adjuvant combined radiotherapy (conformal pelvic EBRT – 3D-CRT, IMRT, VMAT, endovaginal 192Ir HDR brachytherapy) was performed in 33 (64,7%) pts. after radical surgery, adjuvant chemoradiation with Cisplatin 40 mg/m2 or Carboplatin AUC2 weekly – in 8 (24.2%) of them. 18 (35,3%) pts. were treated with definitive chemoradiation, median EQD2 for HR-CTV D90 81.6 ± 4.4 Gy (CI 95% 72.4 Gy – 93.7 Gy) and 54.6 ± 3.3 Gy (CI 95% 48.8–64.2 Gy) for metastatic pelvic and paraaortic lymph nodes.</p><p>Indications for 18F-FDG PET-CT (Biograph True64, Siemens, 3.8–4.7 MBq/kg, total 169–356 MBq) in all pts. were suspicious clinical, cytological, complex ultrasound, and multiparametric MRI findings in pre-irradiated zones. Any areas of 18F-FDG pathologically increased uptake were considered hypermetabolic lesions, positive for cancer recurrence.</p></sec><sec><title>Results</title><p>Results. No evidence of loco-regional recurrence in pre-irradiated zones was confirmed in 32 (62.7%) pts. Clinical, morphological and radiological signs of progression were obtained in 16 (31.3%) 18F-FDG PET-CTpositive patients, with SUVmax 2.86–8.8 in this subgroup. 18F-FDG PET-CT false-positive results were obtained in 6 (11.8%) patients, false-negative – in 1 (1.9%) heavy pre-treated CC patient. 18F-FDG PET-CT sensitivity was 94.1%, specificity – 84.2%, positive predictive value – 72.7%, negative predictive value – 96.9%.</p></sec><sec><title>Conclusions</title><p>Conclusions. 18F-FDG-PET-CT has a high diagnostic value in the differential diagnosis of loco-regional relapses and post-radiation tissue changes in CC and EC patients with suspected progression in pre-irradiated zones. But 18F-FDG-PET-CT findings evaluation and interpretation requires a multidisciplinary discussion and consensus for this cohort of patients.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>рак шейки матки</kwd><kwd>рак тела матки</kwd><kwd>ПЭТ-КТ</kwd><kwd>МРТ</kwd><kwd>лучевая терапия</kwd><kwd>броахитерапия</kwd><kwd>химиолучевое лечение</kwd><kwd>локорегионарный рецидив</kwd><kwd>чувствительность и специфичность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cervical cancer</kwd><kwd>uterine cancer</kwd><kwd>PET-CT</kwd><kwd>MRI</kwd><kwd>radiation therapy</kwd><kwd>brachytherapy</kwd><kwd>chemo-radiation treatment</kwd><kwd>loco-regional recurrence</kwd><kwd>sensitivity and specificity</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">Каприн А.Д., Старинский В.В., Шахзадова А.О.
