P-gp and MRP1 Expression in Parathyroid Tumors Related to Histology, Weight and ^{99 m}Tc-Sestamibi Imaging Results

P-glycoprotein (P-gp) and multidrug resistance-associated protein (MRP) are membrane efflux pumps that may have a role in the kinetics of (99m)Tc-sestamibi (MIBI) in parathyroid tumors. P-gp and MRP1 expression in parathyroid tumors was studied and related to histology, weight and pre- and intraoperative MIBI imaging results.Patient cohort studyTertiary referral centerThirty-three patients underwent radioguided parathyroidectomy for primary or...
