Clinical Characteristics for Predicting Recurrency in Giant Cell Tumor of Bone

Giant Cell Tumor of Bone is classified as benign tumor with unpredictable biological behaviour. Recurrency and metastasis of GCTB could be found in this benign tumor. Many studies reported risk factor for recurrency of GCTB. This study is aimed to determine clinical factors for predict the recurrency in the giant cell tumour of the bone (GCTB). We collected clinical data of GCTB, included age, gender, location of tumor, radiographic, histopathological examination, then we classified GCTB samples into 3 groups, primary, recurrent, and metastatic based on the clinical and histopathological examination. From 52 samples, there were 34 samples of primary GCTB, 7 samples of recurrent GCTB or 13,5%, and 11 samples of GCTB metastatic or 21,1% from all samples GCTB. The incidens of recurrency was higher when the tumor destructed the cortex (Campanacci Grade 3), the location was in manus, and the intervention was curretage. There was a statistical significant difference recurrency between tumor location in manus and other locations (p<0,05). Also, there was siginificant difference recurrency between wide excision and curretage (p<0,05). We concluded that the clinical characteristics that could be predictors for recurrency are tumor location and method of surgery.
