Could the "Stiff Rim Sign" Be an Indicator of Lysyl Oxidase Activity in Breast Cancer?

Abstract

Background: Shear wave elastography (SWE) is a non-invasive and easily applicable imaging modality, which can provide quantitative information of tissue stiffness. Peritumoral high SWE elasticity values (stiff rim sign) has been reported in many studies. Lysyl oxidase (LOX) enzyme is implicated in the formation of peri-tumoral stiffness.
