Abstract

The giant cell tumor of bone (GCTB) is a locally aggressive tumor. Reconstruction methods using -tricalcium phosphate (-TCP) blocks with strong compression resistance in and around the knee joint for GCTB have been reported. Among six cases of GCTB treated using this method, two recurrent cases revealed osteolysis, predominantly within the -TCP block based on plain radiographs or computed tomography, while remodeled host bones were preserved. Implanted -TCP blocks can function as a placeholder to preserve host bone in recurrent cases, leading to a higher probability of joint preservation.

摘要

骨巨细胞瘤（GCTB）是一种具有局部侵袭性的肿瘤。有报道称，采用抗压性强的β-磷酸三钙（β-TCP）骨块对膝关节内及周围的GCTB进行重建。在采用该方法治疗的6例GCTB患者中，2例复发患者显示骨质溶解，主要位于基于X线平片或计算机断层扫描的β-TCP骨块内，而宿主骨得以保留并重塑。植入的β-TCP骨块在复发病例中可作为保留宿主骨的占位物，从而提高保留关节的可能性。
