Recent insights into the pathophysiology of omental metastases.

ABSTRACT

Although, useful in inflammatory conditions, the greater omentum represents an important site of metastasis in peritoneal carcinomatosis and is therefore frequently removed as a staging or therapeutic tool. Apart from the milky spots, omental adipose stem cells, and adipocytes have recently been identified to play a role in the preferential homing of tumor cells to the omentum. The extent of omentectomy and whether a routine omentectomy should be done are still known unknowns.
