Abstract:
:Esophageal cancer staging is important for the treatment of esophageal cancer. Endoscopic ultrasonography (EUS) is a common diagnostic tool for esophageal cancer prior to surgery. However, EUS is unable to accurately discriminate the N-staging of lymph nodes. In order to distinguish an optimized standard for malignant lymph node diagnosis, the present study compared lymph nodes detected by EUS and surgery. A total of 112 patients were preoperatively examined with EUS and staged according to the 7th Edition of the American Joint Committee on Cancer Staging Manual. The results of EUS were compared with surgical findings. The critical values of long diameter, short diameter and lymph node number detected by EUS were >7.5, >5.5 mm and >2, respectively; indexes, including long diameter >7.5 mm, short diameter >5.5 mm, round, low echo, edge smooth, near lesion and detected lymph node number (>2) and T3/4 staging, met significance in the EUS group compared with the surgical group (P<0.05). Furthermore, the area under curve (AUC) value of the EUS (0.801) was superior to the conventional, surgical method (0.779). Although EUS improved the diagnostic accuracy of esophageal N staging, it was not able to satisfactorily distinguish between N2 and N3 staging. Advancements in EUS may enhance its detection ability, further improving the diagnostic accuracy of lymph node metastasis.
