HAX1 and neoplasm: Data from the cDNA panel of breast cancer samples showed a significant relationship between HAX1 expression levels and tumor size (P = 0.004 and P = 0.0015 for T0 vs. T1 and T0 vs. T2-4, respectively) and grade (P = 0.003 and P = 0.0015 for G0 vs. G1-2 and G0 vs. G3, respectively), but for the other prognostic markers no significant relation was detected.
