Reduced folate receptor alpha (FOLR1) protein expression in fallopian tubes from premenopausal women: implications for the FOLR1 CDx assay for mirvetuximab‐soravtansine therapy [PDF]

J Pathol Clin Res
Abstract Mirvetuximab‐soravtansine (MIRV‐S) is an antibody‐drug conjugate targeting folate receptor alpha (FOLR1). MIRV‐S is approved for the treatment of FOLR1‐positive, platinum‐resistant ovarian carcinoma. Patient eligibility is determined by immunohistochemistry (IHC) using a companion diagnostic (CDx) assay (FOLR1‐2.1, Ventana).

Choroid Plexus Neoplasms: Toward a Distinction between Carcinoma and Papilloma Using Arterial Spin-Labeling [PDF]

American Journal of Neuroradiology, 2015
Pediatric choroid plexus papillomas and carcinomas are highly vascularized neoplasms, which are difficult to distinguish with conventional imaging. We aimed to analyze the diagnostic accuracy of PWI, by using both pseudocontinuous arterial spin-labeling and DSC-PWI.
