Oncology Patients Who Develop Transfusion-Associated Circulatory Overload: An Observational Study.

Background: Transfusion-associated circulatory overload (TACO) is a largely preventable transfusion complication that results in significant morbidity and mortality. Cancers, related treatments, and comorbidities are among the factors that can predispose patients to TACO, but currently there are limited data on this topic in the literature.

Methods: We collected data retrospectively from the electronic health records of 93 adult patients with cancer who met Centers for Disease Control and Prevention (CDC) criteria for TACO from July 1, 2019, through October 31, 2020.

International multicentre observational study to evaluate the association between perioperative red blood cell transfusions and 1-year mortality after major cancer surgery (ARCA-1): study design, statistical analysis plan and study protocol.

Introduction: Blood transfusion is still common in patients undergoing major cancer surgery. Blood transfusion can be associated with poor prognosis in patients with cancer. Perioperative Care in the Cancer Patient -1 (ARCA-1) aims to assess in a large cohort of patients the current incidence, pattern of practice and associations between perioperative blood transfusions and 1-year survival in patients undergoing major cancer surgery.
