title: Prognosis of local recurrence in giant cell tumour of bone: what can we do?
abstract: Giant cell tumour of bone (GCTB) is classified as an intermediate tumour with rare metastasis, but is challenged by local recurrence. This review focuses on the role of radiological evaluation in terms of prognosis of local recurrence in GCTB. We hope to highlight the value of radiological evaluation by integrating studies on the impact of surgical treatments and non-surgical factors on local recurrence of GCTB and the current statuses of genetic and molecular prognostic factors of GCTB. Radiological evaluation can provide diverse information on tumours. As a non-invasive method, magnetic resonance imaging (MRI) is especially valuable for the diagnosis and evaluation of bone tumours due to its heightened sensitivity to soft tissue disease and multiplanar image acquisition. Imaging findings should be integrated with clinical characteristics, pathology and genetic and molecular prognostic factors to direct clinical approach and reduce the local recurrence of GCTB. Therefore, it is necessary to establish a multi-perspective evaluation system by which prognostic factors can be reliably determined. We further advocate more large-scale prospective studies. With the help of radiological evaluation, the clinic treatment of GCTB can be guided and local recurrence might be reduced; additionally, MR imaging can identify local recurrence of GCTB after surgical treatment in the early stage.
