Task: Answer Verification
Input (English): Question: Do perioperative blood transfusions impact overall and disease-free survival after curative rectal cancer resection : a propensity score analysis?
Answer: This is the first propensity score-based analysis providing compelling evidence that worse oncological outcomes after curative rectal cancer resection in patients receiving perioperative blood transfusions are caused by the clinical circumstances requiring transfusions, not due to the blood transfusions themselves. Therefore, concerns about overall and disease-free survival should be no issue in the decision-making regarding perioperative blood transfusions in patients undergoing curative rectal cancer resection.
Output (English): no
