    Abstract:
    AIMS: Giant-cell tumour of bone (GCT) represents 5% of all primary bone tumours. The aim of this study was to compare the outcome of GCT treated with or without phenol. METHODS: Out of 53 patients primarily treated for a giant-cell tumour, 47 were followed, with a median follow-up of 11 (range 4-43) years. All patients were disease-free at the latest follow-up. Of the 40 tumours (85%) located in long bones, 14 (35%) were treated by curettage and bone grafting and 12 (30%) by additional adjuvant phenol treatment. Fourteen patients (35%) received different therapies, including en-bloc resection, endoprosthesis, cement packing or other therapy. RESULTS: There were seven (17.5%) recurrences in long bones after a median of 12 (range 4-60) months, three (3/14, 21%) in the group treated without phenol and three (3/12, 25%) in the group with phenol. Of the seven tumours located in the axial skeleton, two patients died within the first year after surgery. The remaining five patients were followed, with a median follow-up of 12 (range 8-23) years. No patients had metastases or a multicentric tumour. CONCLUSIONS: Despite the different rates of recurrence reported in literature, this study suggests that local recurrence rate of giant-cell tumours located in long bones treated with or without phenol is similar. Adequate removal of the tumour seems to be a more important predictive factor for the outcome of surgery than the use of phenol as an adjuvant therapy.
