Fig. 1. Comparison of bone mineral density (BMD) changes between osteosarcoma patients and controls. (A) Lumbar spine BMD (mg/cm2) changes of patients. (B) Femur neck BMD changes of patients. (C) Lumbar spine BMD changes of controls. (D) Femur neck BMD changes of controls. Four patients showed decreased lumbar spine BMD and 7 patients showed decreased femur neck BMD, while all controls showed increased BMDs. The interval from first BMD evaluation to next BMD evaluation was 7.8±1.7 months (vs. 12.0±0.5 months in controls).
