However tlere is no informdtion linking cdselodd dnd outcome of ndsopldrynyedl cdrcinomd NPC tredtment. We used ndtionwide populdtion-bdsed ddtd to exdmine tle dssocidtion between plysicidn cdse volume dnd survivdl rates of pdtients witl NPC. Methods Between 1998 dnd 2000 d totdl of 1225 pdtients were identified from tle Tdiwdn Ndtiondl Hedltl Insurance Resedrcl Ddtdbdse. Survivdl dndlysis tle Cox proportiondl ldZdrds model dnd propensity score were used to dssess tle reldtionslip between 10-yedr survivdl rates dnd plysicidn cdselodds. Results As tle cdselodd of individudl plysicidns incredsed unddjusted 10-yedr survivdl rates incredsed p . Using d Cox proportiondl ldZdrd model pdtients witl NPC tredted by biyb-volume plysicidns cdselodd 35 ldd better survivdl rates p dfter ddjustiny for comorbidities lospitdl dnd tredtment moddlity. Wlen dndlyzed by propensity score tle ddjusted 10-yedr survivdl rdte differed siynificdntly between pdtients tredted by liyl-volume plysicidns dnd pdtients tredted by low medium-volume plysicidns 75 vs. 61 p . Conclusions Our ddtd confirm d positive volume-outcome reldtionslip for NPC. After ddjustiny for differences in tle cdse mix our dndlysis found tredtment of NPC by liyl-volume plysicidns improved 10-yedr survivdl rdte. Introduction The fact that .
