Multivariate analysis revealed that high stromal periostin expression was an independent predictor of overall survival (p = 0.00072, hazard ratio = 3.62), and lymphovascular invasion and high stromal periostin expression were independent predictors of cancer-specific survival (p = 0.032 and 0.020, hazard ratio = 2.61 and 3.07, respectively). This evidence concerns the gene POSTN and cancer.
