Oncologic patients experience anemia and anemia is associated with poor prognosis. Transfusion is associated with adverse events, and equipoise remains on the optimal transfusion strategy in oncologic patients in surgical setting. The primary objective of this study is to determine the impact of anemia and red blood cells (RBC) transfusion on post-operative complications and mortality.

Between 36 and 75% of oncologic patients experience anemia and anemia is associated with poor prognosis. Up to 40% of surgical oncologic patients receive red blood cells (RBC). However, transfusion is associated with adverse events, and equipoise remains on the optimal transfusion strategy in oncologic patients in surgical setting. The primary objective of this study is to determine the impact of anemia and red blood cells (RBC) transfusion on post-operative complications and mortality. This is a retrospective, single center study. All adults admitted to the intensive care unit (ICU) after oncologic surgery within the study period are eligible.

Inclusion Criteria:

• Surgery for cancer
• Admission to intensive care

Exclusion Criteria:

• no consent

All adults admitted to the intensive care unit (ICU) after oncologic surgery from January 2017 to December 2018 are eligible. The following types of surgery for cancer or metastasis resection with a high risk of bleeding are eligible: thoracic, abdominal, neurosurgery, gynecologic, urologic, otorhinolaryngology or spinal surgery.
