The aim of the present study is to systematically review current evidence regarding the association between perioperative blood transfusions (PBT) and oncological outcomes of patients with renal cell carcinoma undergoing nephrectomy procedures. A computerized bibliographic search was conducted to identify pertinent studies. The Population, Intervention, Comparator, Outcome (PICO) study design approach was used to define study eligibility according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) criteria. Only 7 studies were deemed fully eligible for analysis. Most series included both open and laparoscopic cases. The rate of PBT varied between 9.6% and 76.6%, and the median number of transfused units was 2 for most of the studies. At pooled analysis, a statistically significant association was found between PBT and disease recurrence (HR, 1.79; 95% CI, 1.32-2.41; P <.001), cancer-specific mortality (HR, 1.62; 95% CI, 1.29-2.05; P ≤.001), and all-cause mortality (HR, 1.45; 95% CI, 1.25-1.69; P <.001). Current evidence suggests that indeed the use of PBT may be associated with worse oncologic outcomes in patients with renal cell carcinoma undergoing nephrectomy procedures. Although presents findings should be interpreted within the intrinsic limitations of this type of pooled analysis, they emphasize the need for evidence-based strategies to minimize the use of PBT during kidney cancer surgery.

Abstract

The aim of the present study is to systematically review current evidence regarding the association between perioperative blood transfusions (PBT) and oncological outcomes of patients with renal cell carcinoma undergoing nephrectomy procedures. A computerized bibliographic search was conducted to identify pertinent studies. The Population, Intervention, Comparator, Outcome (PICO) study design approach was used to define study eligibility according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) criteria. Only 7 studies were deemed fully eligible for analysis. Most series included both open and laparoscopic cases. The rate of PBT varied between 9.6% and 76.6%, and the median number of transfused units was 2 for most of the studies. At pooled analysis, a statistically significant association was found between PBT and disease recurrence (HR, 1.79; 95% CI, 1.32-2.41; P <.001), cancer-specific mortality (HR, 1.62; 95% CI, 1.29-2.05; P ≤.001), and all-cause mortality (HR, 1.45; 95% CI, 1.25-1.69; P <.001). Current evidence suggests that indeed the use of PBT may be associated with worse oncologic outcomes in patients with renal cell carcinoma undergoing nephrectomy procedures. Although presents findings should be interpreted within the intrinsic limitations of this type of pooled analysis, they emphasize the need for evidence-based strategies to minimize the use of PBT during kidney cancer surgery.
