FOXO3 and renal pelvis/ureter urothelial carcinoma: The results of our study reveal the following: (1) low FOXO3A expression predicts unfavorable survival and recurrence rates in UTUC patients; (2) FOXO3A expression is negatively associated with pathological stage, lymph node metastasis status, lymphovascular invasion, and adjuvant therapy in UTUC patients; and (3) FOXO3A expression is lower in UTUC tissue than in normal tissue.
