Objective: To investigate the application value of computed tomography (CT) examination of lymph node short diameter in evaluating cardia-left gastric lymph node metastasis in thoracic esophageal squamous cell carcinoma (ESCC). Methods: A total of 477 patients with primary thoracic ESCC who underwent surgical treatment in the Affiliated Cancer Hospital of Zhengzhou University from January 2013 to December 2017 were collected. All of them underwent McKeown esophagectomy plus complete two-field or three-field lymph node dissection. Picture archiving and communication system were used to measure the largest cardia-left gastric lymph node short diameter in preoperative CT images. The postoperative pathological diagnosis results of cardia-left gastric lymph node were used as the gold standard. Receiver operating characteristic (ROC) curve was used to evaluate the efficacy of CT lymph node short diameter in detecting the metastasis of cardia-left gastric lymph node in thoracic ESCC, and determine the optimal cut-off value. Results: The median short diameter of the largest cardia-left gastric lymph node was 4.1 mm in 477 patients, and the largest cardia-left gastric lymph node short diameter was less than 3 mm in 155 cases (32.5%). Sixty-eight patients had cardia-left gastric lymph node metastases, of which 38 had paracardial node metastases and 41 had left gastric node metastases. The lymph node ratios of paracardial node and left gastric node were 4.0% (60/1 511) and 3.3% (62/1 887), respectively. ROC curve analysis showed that the area under the curve of CT lymph node short diameter for evaluating cardia-left gastric lymph node metastasis was 0.941 (95% CI: 0.904-0.977; P<0.05). The optimal cut-off value of CT examination of the cardia-left gastric lymph node short diameter was 6 mm, and the corresponding sensitivity, specificity and accuracy were 85.3%, 91.7%, and 90.8%, respectively. Conclusion: CT examination of lymph node short diameter can be a good evaluation of cardia-left gastric lymph node metastasis in thoracic ESCC, and the optimal cut-off value is 6 mm.

While endoscopic submucosal dissection (ESD) is widely used to treat gastrointestinal tumors, it is rarely used for subepithelial tumors (SETs) originating from the muscularis propria of the esophagus and gastric cardia because of the risk of perforation and problems with inadequate space and field of view during procedures. Submucosal tunneling endoscopic resection (STER) is a new therapeutic method for treating SETs in specific locations in the esophagus and stomach. This technique is highly skill-dependent, using a mucosal flap that covers a deeper part of the gut wall, but is safe and minimally invasive compared with conventional endoscopic approaches such as ESD in SETs originating from the muscularis propria.We report a patient who underwent STER to remove a SET located at the gastric cardia. The patient recovered without any complications. We believe that our case shows the efficacy and safety of the STER technique for patients with a SET originating from the muscularis propria.

OBJECTIVETo investigate the correlation between extranodal metastasis (EM) and clinicopathologic features as well as the effect of EM on the prognosis in gastric cardia patients.

METHODSRetrospective analysis was performed for the 323 cases with histologically proven adenocarcinoma of gastric cardia who underwent curative resection from January 2000 to January 2007. There were 272 male patients and 51 female patients with their median age of 63 (22 to 85) years. The relationship between clinicopathological features and extranodal metastasis was studied. The effects of the EM on the recurrence and survival of these patients were also analyzed.

RESULTSEM positive was detected in 67 (20.7%) of the 323 patients. The incidence of EM was correlated with tumor Lauren typing, differentiation degree, invasive depth and lymph node metastasis (χ(2) = 4.647-27.216, P < 0.05). The 5-year survival rate and media survival time between patients with EM and those without EM were 12.3%, 34.1% and 20, 39 months, there was a statistically significantly difference (χ(2) = 23.936, P = 0.000) in 5-year survival rate. Multivariate analysis identified that invasive depth, lymph node metustasis and EM as an independent prognostic factor of all the patients. To the last follow up, the cumulative probability of recurrence of EM-positive patients was significant higher than EM-negative patients (59.7% vs. 35.9%; χ(2) = 12.409, P = 0.000). To study furthermore, stratified analysis showed that, in the node-positive patients, the cumulative recurrence rate of EM-positive patients was higher than EM-negative patients (60.9% vs. 40.0%; χ(2) = 8.410, P = 0.004) and the 5-year survival rate of EM-positive patients was less than the EM-negative patients (12.9% vs. 30.1%; χ(2) = 12.939, P = 0.000), the differences were statistically significant.

CONCLUSIONSEM positive is determined to be an independent prognosis factor of gastric cardia after curative resection. EM-positive patients have a high risk for recurrence and a short time to live.

OBJECTIVE: To assess the value of proximal gastrectomy (PG) and total gastrectomy (TG) for the treatment of cancer of cardia and fundus. METHODS: Publications on comparision between PG and TG in the treatment of cancer of cardia and fundus were collected, the data from the publications were matched with the PG group and the TG group respectively according to its corresponding surgical resection, and the data on postoperative complications, motality and 5-year survival rate were meta-analyzed by fixed effect model and random effect model. RESULTS: Thirteen reseaches on 2 219 patients were included in this study, 2 of which were randomly controlled studies. There were no significant differences in the postoperative complications (OR=1.00, 95%CI: 0.44-2.28,P>0.05) and mortality (OR=1.25, 95%CI: 0.62-2.48,P>0.05) between the PG group and the TG group, while there was significant difference in the 5-year survival rate (HR=0.87, 95%CI: 0.76-0.99,P=0.04). The 5-year survival rate in the TG group was higher than that in the PG group. CONCLUSION Total gastrectomy for the treatment of cancer of cardia and fundus has better long-term therapetic effect.

BACKGROUND AND OBJECTIVETransthoracic and transabdominal approaches are commonly used for the surgical treatment of adenocarcinoma of the cardia. Which approach is better has been controversial for quite a long time. Our study aimed to compare the surgical trauma, range of lymph node dissection, and the prognosis of the transthoracic and transabdominal approaches for the treatment of adenocarcinoma of the cardia.

METHODSThe medical records of 331 patients with adenocarcinoma of the cardia treated in our hospital between 1994 and 2003 were analyzed. Of the 331 patients, 284 underwent operation via transthoracic approach and 47 via transabdominal approach. Surgery-related status, postoperative complications, range of removed lymph nodes and prognosis of the two groups were compared.

RESULTSThere was no significant difference in surgery-related status and postoperative complications between the two groups (P >0.05). The mean number of removed lymph nodes from the thoracic cavity was much higher in transthoracic group than in transabdominal group (P < 0.001), while that from the abdominal cavity was similar in both groups (P = 0.404). The thoracic lymph node metastasis rate was 18.8% in transthoracic group and 13.3% in transabdominal group. The median survival time was 29 months in transthoracic group and 28 months in transabdominal group, and the 5-year survival rates were 34.9% and 40.1% (P= 0.599).

CONCLUSIONSFor the surgical treatment of adenocarcinoma of the cardia, the surgical trauma of the transthoracic approach is similar with that of transabdominal approach. The transthoracic approach has the advantage in thoracic lymph node dissection. The two approaches have no obvious effect on the prognosis.

BACKGROUND/AIMS: The aim of this study was to evaluate clinicopathologic differences between Type II and Type III groups that were classified by Siewert in cardia cancer. METHODS: A hundred forty-one patients who were diagnosed as gastric cardia cancer and underwent surgery between January 1990 and December 2006 by single surgeon at Department of Surgery, Yonsei University College of Medicine were included in this study. The Kaplan-Meier method and log rank test were used for survival analysis. RESULTS: Barrett's adenocarcinoma was recognized in two patients so called type I. There were significant differences between type II and III in aspect of depth of invasion, Lauren's classification, and the number of retrieved lymph nodes in which cancer infiltrated. In type III, prognostic factors affecting survival were depth of invasion and nodal status in contrast to the no demonstrable prognostic factors existing in type II. However, there were no differences in recurrence and survival between two groups. CONCULSIONS: Several clinicopathologic differences exist between type II and III cardia cancer. In the future, further evaluation is needed regarding the classification and entities of the cardia cancer.
