Likewise, the RFS for the samples with high expression levels of ITGAV and ITGB1 was markedly lower than that for the samples with low expression levels of ITGAV and ITGB1, which might indicate that integrin αvβ3/α6β1 could be a potential prognostic element in PCa (Figure 2D, 2E). Here, ITGB1 is linked to posterior cortical atrophy.
