Impact of perioperative blood transfusion on oncologic outcomes in patients with nonmetastatic renal cell carcinoma treated with curative nephrectomy: A retrospective analysis of a large, single-institutional cohort.

The results of this study are inconclusive in that the influence of PBT on survival outcomes could not be determined in the multivariate analysis. However, increasing pRBC units in transfused patients might be a concern in light of worse OS and CSS. Therefore, efforts to limit PBT overuse seem necessary to improve postoperative survival in patients with RCC.
