As shown in Figure 3C, comparing tumor gene expression across different tumor pathological stages, PCA3 expression was higher in pT2 tumors (median: 12.6; IQR: 11.2–13.8) than in tumors that were pT3 (median: 12.2; IQR: 9.7–13.6, [p-value = 0.01]) or pT4 (median: 12.1; IQR: 9.6–12.7, [p-value = 0.61]). This evidence concerns the gene PCA3 and neoplasm.
