We find that FOXO3 is a potential oncogene and that the transcript level of FOXO3 is related to the mutation of TP53 and ARID1A. In addition, FOXO3 may influence immune infiltration and different signal pathways through sponge adsorption of miRNA to impact the prognoses of stomach adenocarcinoma patients.
Multivariate analyses showed that FOXO3A was a significant predictor for OS (HR 2.145, P = 0.014) and RFS (HR 2.227, P = 0.010) in UTUC patients. Our results indicate that FOXO3A may be involved in the recurrence of UTUC and that it has certain clinical value in the therapeutic targeting and prognostic evaluation of UTUC.
