Do Patients After Chondrosarcoma Treatment Have Age-appropriate Bone Mineral Density in the Long Term?
Long-term survivors of chondrosarcoma appear to be at greater risk for having low BMD develop than the healthy population. Although these results are preliminary and based on a very small sampling of patients, if they can be confirmed in larger studies, BMD assessment by dual-energy x-ray absorptiometry might be considered as these patients are followed posttreatment by sarcoma care units. The reasons for low BMD still must be elucidated.
Our data indicate that in vivo α1AMPK deletion leads to Nox2 upregulation, resulting in endothelial dysfunction and vascular inflammation. This implicates basal AMPK activity as a protective, redox-regulating element in vascular homeostasis.
