Due to our exclusion criteria, certain genes of interest were not considered, such as the stemness gene ITGB1, expressed in WBCs and platelets; the prostate‐specific marker ACP3 (prostatic acid phosphatase), involved in PCa bone metastasis but expressed in eosinophils; and the EMT marker VIM, highly expressed in WBCs, which is more relevant in CTCs than in whole‐blood RNA [25, 26, 27]. This evidence concerns the gene ITGB1 and posterior cortical atrophy.
