Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In Siewert type II adenocarcinoma, the relationship between adenocarcinoma sub types and survival, histologic/biologic patterns related to the presence/absence of gastric greater curvature metastases, were investigated.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In order to achieve further data on the biological patterns of intestinal and diffuse subtypes of esophageal adenocarcinoma (Lauren's classification), on the frequency of gastric greater curvature nodal stations and on the clinical relevance, in terms of prognosis and survival, of these parameters, a Siewert type II case series of Siewert type II adenocarcinomas, submitted to primary (no neoadjuvant therapy) surgical, studied, operated upon and followed up, were analysed. According to histologic patterns, cases were ordered in intestinal and diffuse adenocarcinoma sub types (Lauren's classification)and distinguished in Barret's, cardiopyloric, gastric types.

Total Gastrectomy

The esophagus was resected at the arch level of the azygos vein, a frozen section of the resection margin was routinely performed to achieve a proximal clean resection margin. The surgical specimen was comprehensive of distal esophagus, stomach and omentum. Digestive tract continuity was established with Roux-en-Y esophagojejunostomy. Lymphadenectomy was extended to the thoracic stations R 2-4, 7-8-9, and L 4, numbered according to the Mountain's classification \[39\] (Suppl. File 2 Figure A) and to the abdominal stations 1-12, numbered according to the Japanese Research Society for Gastric Cancer (JRSGC) 1998 classification.
