Peritoneal metastasis is a common occurrence in ovarian cancer, whereby cancer cells that have detached from the primary tumor surface are carried by the peritoneal fluid and adhere in large numbers to the peritoneal surface.270 The presence of a substantial number of adipocytes in the peritoneum has been associated with the promotion of tumor cell growth through the release of lipids, cytokines (such as IL-8), and upregulation of fatty acid-binding protein 4 expression.271. This evidence concerns the gene FABP4 and neoplasm.
