Abstract:
Background and purpose:Fatty acid synthase(FAS)is a new tumor marker,the high expression of which has been reported to be associated with poor prognosis of cancer patients.This study investigated the expression of FAS in transitional cell carcinoma(TCC) of bladder and its clinical significance.Methods:The expressions of FAS were detected by streptavidin-peroxidase immunohistochemical method in the paraffin embedded sections of 65 TCC patients and the clinical data had been reviewed.15 normal bladder tissues were used as control group.Results:The positive rate of the expression of FAS in TCC was 58.5%(38/65),while only 2 of 15 cases in control group expressed FAS protein.The difference was statistically significant,the expression of FAS was related to the histological grades and recurrence but not different pathological stages.Survival analysis revealed that the 5-yr survival rate was lower in FAS positive patients than in negative patients(18% vs.44%,P
