Multidrug resistance markers P-glycoprotein, multidrug resistance protein 1, and lung resistance protein in non-small cell lung cancer: prognostic implications

Abstract
The aim of this retrospective study was to comparatively investigate the expression of the three drug-resistance genes P-glycoprotein (P-gp), multidrug-resistance protein 1 (MRP1), and lung resistance protein (LRP), in non-small cell lung cancer (NSCLC) tissues, and to assess possible associations with clinicopathologic features.
