Statistically increased values of cell proliferation (CD34+ CD61+) were observed in prostate adenocarcinoma and hyperplasia cases reported to non-malignant adjacent cell samples (PCa 28.79 ± 10.14; PH-40.65 ± 11.88 vs. C 16.15 ± 2.58, p < 0.05, Table 2, Figure 2). This evidence concerns the gene ITGB3 and prostate adenocarcinoma.
