In-depth analysis of local recurrence of giant cell tumour of bone with soft tissue extension after intralesional curettage.

Purpose: The aim of this study was to assess the local recurrence rate of giant cell tumour of bone (GCTB) with soft tissue extension, to identify characteristics of the soft tissue extension that can best indicate recurrence of GCTB after intralesional curettage.

Materials And Methods: A total of 48 cases of GCTB with soft tissue extension after intralesional curettage were recruited. Patients were divided into two groups based on various objective features of soft tissue extension including size, number, margins, involvement of adjacent tissues, signal intensity, static enhancement and Jaffe grade.
