STAT5A and neoplasm: Multivariate analysis of this cohort revealed that Nuc-Stat5a remained an independent marker of patient outcome after adjustment for other tumor parameters both by CSS (multivariate Cox regression HR = 4.19 (1.13, 15.48); P = 0.032; n = 73) and by TTR (multivariate Cox regression HR = 4.27 (1.20, 15.19); P = 0.025; n = 73).
