Radiotherapy in the treatment of osteoblastoma - a report of five consecutive cases

Osteoblastomas are rare, locally aggressive bone tumours, usually not giving distant metastases. The basic method of treatment is surgery. Radiotherapy is used for unresectable, recurrent and aggressive tumours or after an incomplete excision. We report five patients (age: 16-55 years). In 4 cases the lesions were located in long bones and in 1 case in the pelvis. In all cases curettages were performed, but in 3 we applied postoperative irradiation (45-50 Gy) because of non-radical surgery and aggressive histopathological form. The mean follow-up period was 28.3 months. In the group of irradiated patients we observed partial regression and pain relief in 2 cases and tumour and pain level stagnation in 1 case. We observed no pain relief in patients treated by surgery alone. Rola radioterapii w leczeniu guzow typu osteoblastoma.
