Ovarian cancer metastasis: Looking beyond the surface
Historically, ovarian cancer (OC) was thought to metastasize by surface-to-surface spread, but recent developments have yielded a new understanding of the paths of metastatic spread. Given the histologic and molecular heterogeneity of OC, we will focus on high-grade serous carcinoma (HGSC). Here, we provide a critical and more holistic view of the evidence supporting various routes of metastasis, including peritoneal, hematogenous, lymphatic, and nerve-related. Understanding the underlying mechanisms is necessary to improve treatment strategies for this challenging disease.
