Multidrug (MDR) has been associated with the expression of P-glycoprotein (P-gp), multidrug protein (MRP1), lung (LRP). The aim present study was to compare LMS GIST respect outcome MDR parameters. PATIENTS AND METHODS: Clinical evaluated 29 patients a primary deep-seated 26 GIST. Paraffin-embedded material, available for 25 GIST, used immunohistochemical detection P-gp, MRP1, LRP, c-kit. RESULTS: Mean overall survival (OS) 72 months 31 (P < .05). Metastases occurred 16 (59%) 27 assessable 10 (56%) 18 assessabl...
