Background: While perioperative blood transfusion (BT) has been associated with adverse outcomes in multiple malignancies, the importance of BT timing has not been established.
Objective: The objective of this study was to evaluate whether intraoperative BT is associated with worse cancer outcomes in bladder cancer patients treated with radical cystectomy (RC).
Design, Setting, And Participants: Outcomes from two independent cohorts of consecutive patients with bladder cancer treated with RC were analyzed.
