Ovarian Cancer Clinical Trial
PET/MR Versus CECT Scans in Imaging Patients With Ovarian Cancer or Highly Suspected Ovarian Cancer
This trial studies how well positron emission tomography/magnetic resonance (PET/MR) versus contrast enhanced computerized tomography (CECT) scans work in locating ovarian cancer tumors in patients with known or suspected ovarian cancer. PET, MR, and CECT scans use different methods to create images of areas inside the body. This trial is being done to see if PET/MR scans may help doctors locate ovarian cancer tumors, predict how well these tumors may be removed during surgery, and predict how patients respond to platinum-based chemotherapies compared to standard of care CECT scans.
I. To compare PET/MR and contrast enhanced computed tomography (CT) to determine the accuracy in patients with advanced-stage serous ovarian cancer or highly suspected ovarian cancer using diagnostic laparoscopy as the gold standard with respect to lesion detection.
SECONDARY OBJECTIVES (EXPLORATORY):
I. Correlating imaging findings such as enhancement pattern, apparent diffusion coefficient (ADC) values, standardized uptake value (SUV) values, and advanced image analytics such as texture with pathology and genomic analysis for those lesions evaluated as a discovery arm.
II. Assess whether MR (multiparametric and functional) and PET findings predict response to platinum based chemotherapy.
III. To compare PET/MR and contrast enhanced CT to predict tumor negative (R0) resection using surgery as the gold standard.
Patients undergo standard of care CECT scan and PET-MRI scan over 90-120 minutes within 30 days before laparoscopy or cytoreduction. Patients who do not undergo cytoreduction based on diagnostic laparoscopy undergo additional PET-MRI and standard of care CECT scans after completion of chemotherapy and before cytoreduction.
Patients with ovarian cancer or highly suspected ovarian cancer who are eligible to undergo laparoscopic evaluation for resectability will be enrolled in the trial.
Patients who have estimated glomerular filtration rate (eGFR) > 30.
Patients allergic to gadolinium.
Patients who have eGRF < 30.
Patients with cardiac pacers.
Greater than 400 pounds in weight.
Blood glucose (> 200 mg/dl).
