- Brief Summary
Anemia is common in oncology. Up to three-quarters of cancer patients are exposed to an episode of anemia. In oncology surgery, perioperative bleeding is a major risk factor for anemia. Indeed, 13 to 40% of patients are transfused in perioperative oncologic surgery.
There is an association between anemia and prognosis. Several epidemiological studies have shown a strong association between anemia and altered quality of life. In oncology cohort studies, anemic patients had a significantly lower quality of life compared to patients without anemia. In non-cardiac surgery, preoperative anaemia was significantly associated with post-operative mortality. There is also an association between preoperative anaemia and the occurrence of post-operative complications. In oncology surgery, cohort studies conducted in colorectal surgery and neurosurgery found an association between the occurrence of perioperative anemia and post-operative morbidity and mortality.
The optimal transfusion strategy is unknown in oncology patients. Several multicentre randomised trials, conducted in resuscitation patients or in perioperative settings, have compared a "restrictive" to a "liberal" transfusion strategy. These studies did not show a superiority of one strategy over another on patient outcomes but a lower exposure to red blood cell concentrates in patients transfused with the restrictive transfusion strategy. Thus, the French High Authority for Health (HAS) has adopted a haemoglobin level of 7 g/dl as the transfusion threshold for any transfusion of red blood cell concentrate carried out in the operating theatre and in intensive care in the absence of special cases such as the presence of acute coronary syndrome. For oncology patients, no recommendation could be made due to the lack of evidence-based literature and the optimal transfusion strategy for these patients remains unknown. Only 2 monocentric trials performed in oncology (critical care and perioperative) suggest a benefit of a liberal strategy (transfusion for a haemoglobin level \< 9 g/dl) on the short-term vital prognosis, but these studies suffer from numerous limitations leaving the question unresolved.
Before conducting a large phase III trial, a pilot study is needed to validate the methodology of this multicentre clinical trial and to assess its feasibility.

Group Intervention Description Liberal Group Haemoglobin 9.5 g/dL transfusion of an erythrocyte concentrate in case of haemoglobin below 9.5 g/dL Restrictive group Haemoglobine 7.5g/dL transfusion of an erythrocyte concentrate in case of haemoglobin below 7.5 g/dL
- Primary Outcome Measures
Name Time Method Methodology of the pilot study up to 30 days The difference in mean hemoglobin levels during the perioperative period up to 30 days postoperatively between the two groups will be assessed
- Secondary Outcome Measures
Name Time Method Evaluation of the functional status up to 30 days Test functional status assessment at 30 days postoperatively using the World Health Organization Disability Assessment Schedule (WHODAS) questionnaire.
This questionnaire asks about difficulties due to health/mental health conditions. Health conditions include diseases or illnesses, other health problems that may be short or long lasting, injuries, mental or emotional problems, and problems with alcohol or drugs. The patient must think back over the past 30 days and answer the questions thinking about how much difficulty you had doing the following activities.Evaluation of the functional status after surgery ans anesthesia up to 30 days Test functional status assessment at 30 days postoperatively using the Quality of recovery questionnaire.
The Quality of Recovery-15 (QoR-15) is a psychometrically tested and validated questionnaire.
The QoR-15 was psychometrically evaluated using data collected from patients who responded at all four time intervals.This included: Acceptability and Feasibility; Validity; Reliability; ResponsivenessMonitoring of the quality of the study's execution up to 30 days Compare the percentage of protocol violations in the 2 groups
Epidemiological data of the pilot study up to 90 days Post-operative complications, occurring between surgery and the 30th day after surgery or before discharge from hospital will be assessed
Adverse Reaction Monitoring up to 30 days To compare the occurrence of transfusion-related adverse events in each group
