Retrospective analysis shows PET/CT with 18F-FDG effectively identifies metastases in lymph nodes, suggesting its diagnostic value.
Purpose: To study the diagnostic value of PET/CT with 18F-FDG in evaluation of metastases in lymph nodes of esophageal cancer. Materials and methods: The retrospective study included 70 patients with squamous cell esophageal cancer. All patients underwent PET/CT with 18F-FDG from 2020 to 2024 in the N.N. Blokhin National Medical Research Center of Oncology. Metastases in the regional lymph nodes were-evaluated by PET/CT with 18F-FDG. Histological verification was performed in all cases. Results: PET/CT with 18F-FDG demonstrated sensitivity 86 % and specificity 78 % of visualization of metastases in the regional lymph nodes. Conclusion: PET/CT with 18F-FDG is a promising imaging method in evaluation of cancer extent squamous cell esophageal carcinoma, detecting metastases in unchanged lymph nodes. PET/CT limitations require a comprehensive diagnostic approach.
