Abstract
Introduction
Androgen deprivation therapy (ADT) for prostate cancer negatively affect areal bone mineral density (aBMD); however, its impact on volumetric BMD (vBMD) and bone geometry remains underexplored. This study aimed to evaluate changes in aBMD, vBMD, and hip structural analysis (HSA) following one year of ADT.
Materials and methods
This retrospective observational study included 41 patients with prostate cancer without bone metastasis who received ADT for one year and underwent dual-energy X-ray absorptiometry (DXA) both before and after treatment. In addition to aBMD, trabecular and cortical vBMD, integral vBMD (trabecular + cortical), cortical surface BMD (sBMD), cortical thickness, and hip structural parameters were assessed at the hip using 3D-Shaper software.
Results
The mean age and body mass index of the patients were 75.5 ± 6.8 years and 24.0 ± 3.0 kg/m2, respectively. More than half had a Gleason score of 4 or 5, and the majority had T3 disease. After one year of ADT, significant reductions in aBMD were observed at the lumbar spine (–4.5 ± 4.0 %, P < 0.001) and total hip (–3.7 ± 5.1 %, P < 0.001). 3D-DXA analysis revealed significant declines in integral vBMD (–3.8 ± 3.9 %) and trabecular vBMD (–4.9 ± 7.4 %) (both P < 0.001), while cortical vBMD showed no significant change (–1.6 ± 6.0 %, P = 0.062) at the total hip. Cortical sBMD decreased significantly by –2.7 ± 5.2 % (P < 0.001). Cortical thickness also significantly decreased at the total hip (–1.2 ± 3.2 %, P = 0.011). With respect to hip structural parameters, cross-sectional area consistently decreased, and buckling ratio increased across the femoral neck, trochanteric, and shaft regions (all P < 0.05), indicating increased femoral fragility and reduced resistance to axial and compressive forces.
Conclusions
ADT exerts a substantial detrimental effect on bone strength, resulting in reductions in aBMD, vBMD, and alteration of HSA. 3D-DXA may serve as a valuable and accessible tool for detecting structural bone changes in prostate cancer patients undergoing ADT.
期刊介绍:
The Journal of Bone Oncology is a peer-reviewed international journal aimed at presenting basic, translational and clinical high-quality research related to bone and cancer.
As the first journal dedicated to cancer induced bone diseases, JBO welcomes original research articles, review articles, editorials and opinion pieces. Case reports will only be considered in exceptional circumstances and only when accompanied by a comprehensive review of the subject.
The areas covered by the journal include:
Bone metastases (pathophysiology, epidemiology, diagnostics, clinical features, prevention, treatment)
Preclinical models of metastasis
Bone microenvironment in cancer (stem cell, bone cell and cancer interactions)
Bone targeted therapy (pharmacology, therapeutic targets, drug development, clinical trials, side-effects, outcome research, health economics)
Cancer treatment induced bone loss (epidemiology, pathophysiology, prevention and management)
Bone imaging (clinical and animal, skeletal interventional radiology)
Bone biomarkers (clinical and translational applications)
Radiotherapy and radio-isotopes
Skeletal complications
Bone pain (mechanisms and management)
Orthopaedic cancer surgery
Primary bone tumours
Clinical guidelines
Multidisciplinary care
