Conclusion PET/CT predicts a higher nodal and overall stage than pathologic staging. PET/CT should not be relied upon for initial tumor staging, as increased FDG uptake is not specific for nodal metastases. PET/CT is shown to be a poor predictor of ECE.

If you have an operation, a pathologist studies tissue the surgeon removed and assigns it a “pathologic stage.” In general, the pathologic stage is the most important one in making treatment decisions. What is the TNM system? Doctors throughout the world use the tumor, lymph node, and ...
Early-stage type 1 and PPI-associated tumors are treated with endoscopic resection without lymph node sampling. Consequently, pathologic stage could not be assigned for most gastric NETs identified in the National Cancer Data- base (NCDB) due to unknown N status. Therefore, overall survival is ...
