For people with the grim diagnosis of pancreatic cancer, the news may have gotten just a shade brighter. Researchers at the Mayo Clinic Comprehensive Cancer Center found that using 18-fluorodeoxyglucose (FDG) tracer with positron emission tomography (PET) provides a preoperative predictor of tumor response to chemotherapy and survival in patients with borderline resectable or locally advanced pancreatic cancer. The finding could change recommended practice for one of the deadliest forms of cancer and improve outcomes for patients.
