Abstract:
PURPOSE: The purpose of the study was to compare clinical, oncological outcomes between chondroblastoma and giant cell tumor. MATERIALS AND METHODS: This retrospective study reviewed 25 patients with histologically confirmed chondroblastoma of bone between 1998 and 2012. During the same period, 42 patients diagnosed as a giant cell tumor were also reviewed. We then analyzed clinical and oncological results of chondroblastoma compared with giant cell tumor. In chondroblastoma, 17 cases were male, and 8 cases were female, with a mean age of 20.6 years (range from 11 to 38 years). In giant cell tumor, 20 cases were male, and 22 cases were female, with a mean age of 39.26 years (from 17 to 75 years). All patients underwent surgical treatment that extended curettage with electrocauterization. After curettage, bony cavity was filled with autogenous bone, allogenic bone chip, bone cement, tricalcium phosphate, and so on. The results were compared in recurrence and metastatic rate. The minimum follow-up period was 1 year. RESULTS: In chondroblastoma, mean size was 2.18 cm (0.3 to 9.5 cm). Local recurrence and metastasis were absent. In giant cell tumors, mean size was 3.71 cm (0.3 to 11 cm). Local recurrence rate was 9.5% (4 of 42 cases) and there was one lung metastasis. CONCLUSION: Chondroblastoma is less invasive with better prognosis than giant cell tumor. Treatment of chondroblastoma and giant cell tumor is surgery. Electrocauterization as an adjuvant therapy showed good results.
