Wernicke et al. detected PSMA expression in the tumor vessels of all the 21 ovarian cancer samples analyzed and in 10 cases on the tumor cells; they also compared the PSMA expression levels in metastatic tumor foci, showing higher or similar rates of PSMA-positive capillaries than their respective primary ovarian tumors [101]; similar results have been reported by Hofstetter et al., who found PSMA expression in the great majority of ovarian cancer samples and suggesting a direct correlation with OS [102]. This evidence concerns the gene FOLH1 and ovarian cancer.
