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

Patients are intravenously infused with 28g of \[U-13C\]glucose over a 5 hour period. Briefly, \[U-13C\]glucose will be provided by intravenous line containing 8g of \[U-13C\]glucose in 60 mL over 10 min. After 10 minutes, 4g of \[U-13C\]glucose will be administered over an hour. This process will continue until the patient's ascites is drained, or after 5 hours. We will monitor blood glucose levels during infusions using a continuous glucose monitor.
