Staging of esophageal cancer by EUS: staging accuracy revisited

Comparison of endoscopic ultrasonography (EUS), positron emission tomography (PET), and computed tomography (CT) in the preoperative locoregional staging of resectable esophageal cancer

“…In our study, the accuracy of EUS for T staging was shown to be no greater than 72%, which was in concordance with Shimpi et al [6], who had similar study settings. Our results could be explained by patient selection bias because we included only patients who were potential candidates for curative surgery.…”

“…Findings have shown that EUS has the ability to delineate the individual esophageal layers and accurately assess the depth of tumor invasion [6].…”

Integrated PET/CT Fusion Imaging and Endoscopic Ultrasound in the Pre-operative Staging and Evaluation of Esophageal Cancer

“…The staging accuracy of EUS has been well-documented by multiple previous studies to be approximately 61-76% for T staging and 55-90% [24] for N staging depending on whether the lesion is traversable [25][26][27], which is comparable to the accuracy we found in our study in patients who underwent surgery without neoadjuvant therapy. Currently, there is a paucity of PET/CT staging accuracy data; however, our study determined nodal staging accuracy of PET/CT to be 52.0% in our patient subset (N=24) which again likely reflects the difficulty in identifying locoregional adenopathy even with fused PET/ CT imaging as it is difficult to separate a locoregional node from a primary tumor.…”

Endoscopic polypectomy: A promising therapeutic choice for esophageal carcinosarcoma

“…Imaging methods such as EUS, CT and positron emission tomography (PET) play an important role in TNM staging. Compared with CT and PET, EUS is superior for T and N staging of esophageal cancer [8,9] . Esophagectomy has been traditionally considered the first option for esophageal carcinosarcoma patients [1] .…”
