Thirty-four cases of giant cell tumour of bone were analysed. Of the 9 patients (grade I and II) treated by curettage and bone grafting 2 patients developed a local recurrence. Of the 9 patients (grade I and II) treated by en bloc resection there was one recurrence. Due to technical reasons in 2 patients only partial excision was done and both had local recurrence. Ten patients, incidentally belonging to grade I, were treated by radiation, more than 50 percent developed recurrence and one developed sarcoma 8 years after irradiation. Histopathological grading was found of not much importance as far as the recurrence rate was concerned but it may have some value in determining the chances of the tumour behaving like a frankly malignant tumour. Complete resection of the tumour by excision of tumour bearing bone gave the best results.
