RHOB and neoplasm: Statistical analysis of the results indicated that RhoB expression in tumors is strongly correlated with the percentage of ERα (Spearman's ρ = 0.3659, P = 0.001) and PR (ρ = 0.2544, P = 0.0076) expression, but inversely correlated with histological tumor size (ρ = -0.2344, P = 0.0166) and number of mitoses (ρ = -0.2009, P = 0.0362).
