STAT5A and neoplasm: In tumor tissues, four protective genes (JAK2, IL2RG, EEF1E1, and UBB) showed relatively low expression in the high‐risk group; in contrast, the expression of four risk genes (EPS8, FOXO1, STAT5A, and PAPPA) was more highly in the high‐risk group than that in the low‐risk group.
