Categorized data were analyzed using the Pearson’s Chi square test or Fisher’s exact probability test.
Accuracy of preoperative diagnosis of lymph node metastasis for thoracic esophageal cancer patients from JCOG9907 trial. Lymph nodes were considered malignant if three or more of the following B-mode criteria were present: lymph node >5 mm in width, round shape, hypoechoic pattern, and smooth border . 12 Systematic radiologic imaging on healthy volunteers is scarce. 2013;20(6):1978–84.This work was supported, in part, by Grants-in-Aid for Scientific Research from the Ministry of Education, Culture, Science, Sports and the Japan Science and Technology Agency.The authors have received no grant support or other forms of assistance.Department of Thoracic Surgery, Akita University Graduate School of Medicine, 1-1-1 Hondo, Akita, 010-8543, JapanAkiyuki Wakita, Satoru Motoyama, Yusuke Sato, Yuta Kawakita, Yushi Nagaki, Kaori Terata, Kazuhiro Imai & Yoshihiro MinamiyaYou can also search for this author in Hölscher AH, Bollschweiler E, Schröder W, Metzger R, Gutschow C, Drebber U.Ann Surg. 2018;154(2):360–73.Tachimori Y, Ozawa S, Numasaki H, Ishihara R, Matsubara H, Muro K. et al; Registration Committee for Esophageal Cancer of the Japan Esophageal Society.

Unable to load your delegates due to an error Although detection of LN metastasis on CT depends primarily on the size criteria, past reports have shown that the sensitivity of CT is unsatisfactory when LNs greater than 10 mm are considered positive for metastasis [We assume that CT scanning will continue to play a dominant role with the introduction of artificial intelligence, when not only the size, but also clinical factors such as the distribution of false-negative LNs and their frequent regions will be considered for determination of LN metastasis.

Aims: The aim of this study was to identify molecular markers predicting depth of tumor infiltration and presence of lymph node metastasis in early esophageal cancer. Surgical staging of esophageal cancer. Among the 85 false-negatives, the right paracardial LNs were most frequently metastatic (18.8%, 16/85LNs), followed by lesser curvature LNs (17.6%, 15/85LNs) and left recurrent nerve LNs (11.8%, 10/85LNs)The regions of false-negative LNs in patients with primary tumors in the upper, middle, or lower thoracic esophagus are summarized in Fig.

Histopathological findings were classified according to the UICC TNM classification [For each false-negative LN diagnosed microscopically, one-to-one correlation was made retrospectively with preoperative CT images.
