There has been a large amount of speculation concerning the differences in the outcomes in patients who have gastric cancer in the Eastern and Western worlds. The differences in biology, surgical and adjuvant treatment have been used to explain such differences. There are clear differences observed in the histology (diffuse vs. intestinal), tumor location (proximal vs. distal), environmental exposures, dietary factors and Helicobacter pylori status. A higher incidence of gastric cancer in the East has led to screening programs, and leading to an earlier stage at presentation. Surgical treatment differs in that the extended lymph node dissection is routinely practiced in the Asian countries. Additionally, different adjuvant therapeutic regimens are used in both regions. The purpose of this review is to describe the differences in both presentation and treatment between the East and the West.

Increased BMI is a predictor of increased postoperative complications, including anastomotic leak, but it is not a predictor of survival in gastric cancer.

Positive resection margin is associated with advanced AJCC stage and aggressive tumor biology but remains an independent predictor of worse survival. The significance of a positive margin in gastric cancer is confined to patients with nontransmural disease and/or limited nodal involvement.

In this study, patients who were able to undergo resection following treatment of initial stage III pancreatic cancer experienced survival similar to those who were initially resectable. Resection is indicated in this highly select group of patients.

Splenectomy is an effective procedure in the diagnosis and treatment of haematological disease in selected patients.
