Could removing blood before surgery reduce transfusions in ovarian cancer patients?
NCT ID NCT06290193
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests a technique called acute normovolemic hemodilution (ANH) in 86 women having surgery for advanced ovarian cancer. Before surgery, some blood is removed and stored, then returned during or after the operation. The goal is to see if this reduces the need for donor blood transfusions. Participants are randomly assigned to receive ANH or standard care.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- acute normovolemic hemodilution (ANH) - a procedure where some blood is removed before surgery and returned later
- What this could lead to
- If it works, this technique could reduce the need for donor blood transfusions during ovarian cancer surgery, lowering risks like infection or allergic reactions.
- What could go wrong
- This is a small, early-phase trial (86 people) testing a procedure, not a new drug. It may not significantly reduce transfusions, and the technique itself carries risks like low blood pressure or anemia during surgery.

Inclusion Criteria: * Adults (≥18 years) * BLOODS score ≥2 as calculated by surgeon * High preoperative suspicion (or diagnosis) of advanced primary epithelial ovarian, fallopian tube, or primary peritoneal carcinoma (stage IIIC or IV), as determined by CT or MRI of the abdomen/pelvis * Planned for exploratory laparotomy and primary or interval cytoreductive surgery * Preoperative hemoglobin concentration ≥10 mg/dl within 45 days of surgery * Patients scheduled for cytoreductive surgery, with or without other planned procedures o Note: Patients scheduled for only diagnostic laparoscopy should not be included Exclusion Criteria: * A history of active coronary artery disease o Patients with a history of coronary artery disease will be eligible if they have had a cardiac stress study showing no reversible ischemia and normal LV function within 45 days of surgery. * A history of cerebrovascular disease * A history of congestive heart failure * A history of uncontrolled hypertension * A history of restrictive or obstructive pulmonary disease * A history of renal dysfunction (Cr \>1.6 mg/dl) * Abnormal coagulation parameters (INR \>1.5 not on coumadin, or platelet count \<100,000 mcL) * Presence of active infection * Evidence of hepatic metabolic disorder (bilirubin \>2 mg/dl, ALT \>75 U/L in the absence of biliary tract obstruction) * Preoperative autologous blood donation within last 30 days or plan to donate autologous blood prior to surgery * Refusal to accept allogenic or autologous blood transfusion * Patients scheduled for cytoreductive surgery with planned Hyperthermic Intraperitoneal Chemotherapy (HIPEC)
