PTEN and posterior cortical atrophy: Songet al. (2017) performed a meta-analysis withdifferent types of cancer, including PCa and the associated risk of cancer forcarriers of the G allele in an Asian population. In this study, we did not find anyassociation between the variants of this gene and susceptibility to PCa.Nonetheless, in all genotypic combinations in which we detected a greater risk ofextracapsular extension, the G allele of the (rs2735343) PTEN genewas present (Table 4), which seems to confirmthe above-cited hypotheses.
