Cervical ultrasonography has no additional value over negative <sup>18</sup>F-FDG PET/CT scans for diagnosing cervical lymph node metastases in patients with oesophageal cancer.
Overall, 18F-FDG PET/CT have a moderate to low sensitivity and a high to moderate specificity for detection of regional nodal metastasis in esophageal cancer.
This study aimed to evaluate the diagnostic performance of <sup>18</sup>F-FDG PET/CT for the detection of interval metastasis and to identify predictors of interval metastases in a large cohort of oesophageal cancer patients.
The analysis included diagnostic studies describing the accuracy of cervical ultrasonography and integrated F-FDG PET/CT or standalone F-FDG PET and CT for detecting cervical lymph node metastases in patients with esophageal cancer.
Relative change in FDG uptake after 14 days of CRT is not associated with DFS in patients with esophageal cancer undergoing neoadjuvant chemoradiotherapy followed by surgery.
Texture analysis of <sup>18</sup>F-FDG PET/CT to predict tumour response and prognosis of patients with esophageal cancer treated by chemoradiotherapy.
