Lymph node involvement in advanced gastroesophageal junction adenocarcinoma
The prognosis of gastroesophageal junction adenocarcinoma is unquestionably related to the extent of nodal involvement; nonetheless, few studies deal with the pattern of lymph node spread and specifically analyze the prognostic value of the site of metastasis. The present study was aimed at evaluating these key aspects in advanced gastroesophageal junction adenocarcinoma.
Of 219 patients consecutively operated on for gastroesophageal junction adenocarcinoma at the Department of General Surgery and Surgical Oncology, University of Siena, and at the Department of General Surgery, University of Verona, 143 pT2-4 tumors not submitted to prior chemoradiation were analyzed according to the Japanese Gastric Cancer Association pN staging system.
The majority of patients were given diagnoses of nodal metastases (77.6%). The mean number (P = .076) and the percentage of patients with pN+ disease (P = .022) progressively increased from Siewert type I to type III tumors. Abdominal nodes were involved in all but 1 of the patients with pN+ disease; conversely, nodal metastases into the chest were 46.2% for type I, 29.5% for type II, and 9.3% for type III tumors. Survival analysis showed virtually no chance of recovery for patients with more than 6 metastatic nodes or lymph nodes located beyond the first tier.
In advanced gastroesophageal junction adenocarcinoma, the high frequency of nodal metastases and the related unfavorable long-term outcome achieved by means of surgical intervention alone are indicative of the need for aggressive multimodal treatment along with surgical intervention to improve long-term results.

- "As it is currently defined, GEJ adenocarcinoma encompasses tumors occurring within 5 cm proximal or distal to the gastroesophageal junction . GEJ adenocarcinoma is associated with a poor prognosis, with a 5-year overall survival (OS) rate of only 10–15%, largely owing to its rapid lymphatic and hematogenous metastasis –. Increasing evidence indicates that GEJ adenocarcinoma differs from gastric and esophageal cancers in both molecular and clinical aspects . "

ABSTRACT: Gastroesophageal junction (GEJ) adenocarcinoma carries a poor prognosis that is largely attributable to early and frequent metastasis. The acquisition of metastatic potential in cancer involves epithelial-to-mesenchymal transition (EMT). The metastasis-associated gene MTA3, a novel component of the Mi-2/NuRD transcriptional repression complex, was identified as master regulator of EMT through inhibition of Snail to increase E-cadherin expression in breast cancer. Here, we evaluated the expression pattern of the components of MTA3 pathway and the corresponding prognostic significance in GEJ adenocarcinoma. MTA3 expression was decreased at both protein and mRNA levels in tumor tissues compared to the non-tumorous and lowed MTA3 levels were noted in tumor cell lines with stronger metastatic potential. Immunohistochemical analysis of a cohort of 128 cases exhibited that patients with lower expression of MTA3 had poorer outcomes. Combined misexpression of MTA3, Snail and E-cadherin had stronger correlation with malignant properties. Collectively, results suggest that the MTA3-regulated EMT pathway is altered to favor EMT and, therefore, disease progression and that MTA3 expression was an independent prognostic factor in patients with GEJ adenocarcinoma.

- "de Manzoni et al.(16)'s study suggested to perform total Gastrectomy with D2 lymphadenectomy with advanced cardia cancer type II or III. Pedrazzani et al.(26)'s study said that chest nodal involvement rate was 46.2% in type I, 29.5% in type II, 9.3% for type III. Siewert et al.(18)'s study suggested that lower mediastinal nodal involvement rate was 12% in type II, 5% in type III. "

ABSTRACT: The aim of this study was to evaluate the surgical outcomes of abdominal total gastrectomy, without mediastinal lymph node dissection for type II and III gastroesophageal junction (GEJ) cancers.
We retrospectively reviewed surgical outcomes in 67 consecutive patients with type II and III GEJ cancers that were treated by the surgical resection between 2004 and 2008.
Thirty (45%) patients had type II and 37 (55%) had type III tumor. Among the 65 (97%) patients with curative surgery, 21 (31%) patients underwent the extended total gastrectomy with trans-hiatal distal esophageal resection, and in 44 (66%) patients, abdominal total gastrectomy alone was done. Palliative gastrectomy was performed in two patients due to the accompanying peritoneal metastasis. The postoperative morbidity and mortality rates were 21.4% and 1.5%, respectively. After a median follow up of 36 months, the overall 3-years was 68%, without any differences between the Siewert types or the operative approaches (transhiatal approach vs. abdominal approach alone). On the univariate analysis, the T stage, N stage and R0 resection were found to be associated with the survival, and multivariate analysis revealed that the N stage was a poor independent prognostic factor for survival.
Type II and III GEJ cancers may successfully be treated with the abdominal total gastrectomy, without mediastinal lymph node dissection in the Korean population.

ABSTRACT: Detection of the esophagogastric junction adenocarcinoma in symptomatic stage determine a low survival. The aim of the study was to identify the prognostic factors after eso-gastrectomy for esophagogastric junction adenocarcinoma. There was done a prospective study of a 43 patients with esophago-gastric resections and abdomino-mediastinal lymph nodes dissection between 2001 and 2006 at the General and Esophageal Surgery "St. Mary" Clinical Hospital: 25 patients with transhiatal total gastrectomy, 6 patients with total gastrectomy and distal esophagectomy by separated incisions, abdominal and thoracic, 3 patients with total gastrectomy and subtotal esophagectomy by abdomino-cervical approach, 9 patients with subtotal esophagectomy by abdomino-cervical approach with cu small gastric curvature resection, radical resections in 22 patients. The patients were followed by clinic, endoscopic, TC exam and tumoral markers. There were done complex statistic analysis using SPSS 16.0. The mean interval of the surveillance was 24 months (6 - 60 months). 1 year survival was 77,74%. Long-term survival was influenced by age (p_value = 0.0129), tumoral grading (p_value = 0.0297), the number of lymph nodes metastasis (p_value = 0.0029) and pT stage (p_value = 0.0139), and was not dependent on Siewert type, ASA class, surgical approach, resection type, the number of the dissected lymph nodes, abdominal or mediastinal. In locally advanced esophagogastric junction adenocarcinoma, the frequency of lymph nodes metastasis (81%) especially in patients with tumoral type III and unfavorable results of surgical treatment as unique therapeutically method show the necessity of a multimodal approach pre and post-operatory by using selection methods with a good prediction of neoadjuvant treatment.
