Factors Influencing Family Burden in Pediatric Hematology/Oncology Encounters.

Purpose: Caring for a child with cancer or hematologic disease places unique stress on a family unit. Families' subjective experience of this care-related burden mediates the relationship between cost and health-related outcomes. While financial costs are well described for families of pediatric hematology/oncology patients, it is unclear how cost and other factors each contribute to families' overall experience of care-related burden.

Aerobic Glycolysis as a Marker of Tumor Aggressiveness: Preliminary Data in High Grade Human Brain Tumors.

Objectives: Glucose metabolism outside of oxidative phosphorylation, or aerobic glycolysis (AG), is a hallmark of active cancer cells that is not directly measured with standard (18)F-fluorodeoxyglucose (FDG) positron emission tomography (PET). In this study, we characterized tumor regions with elevated AG defined based on PET measurements of glucose and oxygen metabolism.

Methods: Fourteen individuals with high-grade brain tumors underwent structural MR scans and PET measurements of cerebral blood flow (CBF), oxygen (CMRO2) and glucose (CMRGlu) metabolism, and AG, using (15)O-labeled CO, O2 and H2O, and FDG, and were compared to a normative cohort of 20 age-matched individuals.
