13C-Glucose Tracing of Tumour and T Cells in the Ascites of Ovarian Cancer Patients.

This study explores how cancer cells and immune cells use sugar (glucose) for energy in the fluid that builds up in the abdomen (called ascites) of ovarian cancer patients. Researchers give a specially labeled glucose through an IV and then analyze the collected fluid to better understand tumor metabolism — which could lead to new treatments. **You may be eligible if...** - You have ovarian cancer at any stage - You have fluid buildup in your abdomen that needs to be drained - You are able to understand the study and give your consent **You may NOT be eligible if...** - You have diabetes or abnormal blood sugar control (abnormal HbA1c) - Your blood glucose is outside the normal range on the day of the infusion - You are receiving chemotherapy during the 5-hour study period Talk to your doctor to see if this trial is right for you.
