Ascites modulates cancer cell behavior, contributing to tumor heterogeneity in ovarian cancer

Abstract

The ascites of cancer is a unique tumor-microenvironment, providing a physical structure for the accumulation of cellular and acellular components. Ascites is initiated and maintained by physical and biological factors resulting from underlying disease and forms an ecosystem that contributes to disease progression. It has been demonstrated that the cellular contents and the molecular signatures of ascites change continuously, during the course of a disease. Over the last decade, increasing attention has been given to the characterization of components of ascites and their role in the progression of ovarian cancer, the most malignant gynecologic cancer in women. This review will discuss the role of ascites in disease progression, in terms of modulating cancer cell behavior and contributing to tumor heterogeneity from molecular levels to clinical implication in ovarian cancer.
