Significance of Omental Infiltration in Gastric Cancer Patients: a Retrospective Cohort Study



Stomach cancer is a curative disease in early stages. The optimal extent and approach for gastric resection are still evolving.

Patients and Methods

In this study, we examined the value, as well as, the predictors of omental disease spread, retrospectively, in a group of patients with gastric cancer who attended the Oncology Center, Mansoura University, in the period between January 2006 and April 2017.


Nodal metastasis, especially heavy disease (N2 and beyond), and advanced stage are predictors of the presence of omental disease. However, neither overall nor disease-free survival is affected by omental infiltration.


Omental resection will continue being an integral part of gastric resection, but the level of omental cutting needs further studies.
