BCAT2 and posterior cortical atrophy: The results of univariate Cox regression analysis showed that BCAT2 expression, Gleason score, T stage, and N stage were significantly associated with BFFS (Fig. 1I), while multivariate Cox regression analysis revealed that high BCAT2 expression and lymph node involvement were independent prognostic risk factors for BFFS of PCa patients (Fig. 1J and Table S3).
