Pretreatment serum xanthophyll concentrations as predictors of XXXX recurrence and survival.

@entity1 @entity135 @entity4793 @entity3092 @entity204 @entity71440
BACKGROUND: The purpose of this study was to examine associations of pretreatment serum carotenoids, @entity4793 , and @entity3092 with prognosis in 154 @entity1 newly diagnosed with @entity135 . METHODS: Pretreatment blood and health surveys were collected. Serum micronutrients were measured by high performance liquid chromatography. Data on recurrence and @entity204 were collected annually. Cox proportional hazards models measured associations of serum nutrient concentrations with recurrence and overall survival. RESULTS: During a median follow-up time of 37 months, there were 32 recurrences and 27 @entity204 . After controlling for covariates, subjects with high versus low serum xanthophyll and total carotenoid concentrations had significantly longer recurrence-free time (p   =   .002 and p   =   .02, respectively). Overall survival time was significantly longer in @entity1 with high versus low serum xanthophyll concentrations (p   =   .02). CONCLUSION: Future research should evaluate the possible benefits of interventions to increase intakes of rich food sources of @entity71440 in this @entity1 population.    2015 Wiley Periodicals, Inc.
