HOXA11 and cancer: Using Cox multivariate analysis in three studies from Kim et al. [14, 17], Sun et al. [31], and Wang et al. [26], we found that elevated HOXA11-AS expression level was an independent prognostic factor of OS for cancer patients (pooled HR = 1.184, 95% CI 1.050–1.335, p = 0.006), without significant heterogeneity among studies (p = 0.07; I2 = 62.4%).
