A pre-operative scoring model to estimate the risk of blood transfusion over an ovarian cancer debulking surgery (BLOODS score)
Surgical procedures required for the initial treatment of ovarian cancer are complex and lengthy, frequently involving blood loss. Meaning transfusion of donated blood is necessary. Previous studies have shown that blood transfusion occurs in 40 –70% of initial ovarian cancer debulking surgical procedures.
Blood transfusion is not without hazard. Those patients who require blood have increased risk of infection, altered immunity, and higher mortality, and morbidity. This article tests a scoring system which can assist by identifying patients likely to require transfusion prior to surgery. With this knowledge, it may be possible to reduce the need for transfusion by the use of blood-saving techniques.
The score is calculated using serum levels of CA125, albumen and hemoglobin, with clinical assessment of tumour size and spread. Retrospective assessment showed that the score predicts transfusion in three quarters of women who will require it as part of the operative clearance of ovarian cancer.
