Implication

Observational cohort study shows high accuracy of combined 11C-choline and 18F-FDG PET for detecting lymph node metastases in esophageal cancer, indicating improved preoperative staging.

Key Points

To evaluate the diagnostic accuracy of dual-tracer PET using 11C-choline and 18F-FDG compared with CT and postoperative pathology for identifying lymph node metastases in patients with esophageal carcinoma.
Evaluated 33 patients with biopsy-proven esophageal carcinoma (16 with T1 and 17 with T2–4 stage tumors).
Performed PET imaging with both 11C-choline and 18F-FDG, alongside computed tomography (CT).
Correlated imaging results directly with histopathological findings obtained after surgical resection.
11C-choline PET outperformed 18F-FDG PET and CT for detecting small mediastinal lymph node metastases, but failed in the upper abdomen due to physiological liver uptake.
18F-FDG PET was superior to CT across mediastinal and upper abdominal regions, whereas 11C-choline PET was more effective specifically in the mediastinum.
Combining 11C-choline PET and 18F-FDG PET successfully identified 85% of metastatic lymph nodes (n = 46) across both mediastinal and upper abdominal sites.
