SURGICAL TREATMENT RESULTS IN GIANT-CELL TUMOR OF THE BONE
Giant-cell tumor of the bone is a benign tumor with high local aggressiveness and risk of recurrences. The aim of our study is to emphasize the importance of the tumor’s size, location and activity in choosing the proper surgical method for treating GCTB, in order to maintain a balance between minimal chance of recurrence and an optimal quality of life. We conducted a retrospective study of a series of 53 patients (age range 21-47 years old) with GCTB confirmed by anatomopathological examination. We used the Enneking grading system and we included 9 patients (16.98%) with first stage tumors, 36 patients (67.92%) with second stage tumors and 8 patients (15.09%) with third stage tumors. The tumors were located in: distal femur – 21 patients (39.62%), proximal tibia – 18 patients (33.96%), proximal femur – 9 patients (16.98%) and distal radius – 5 patients (9.43%). All patients underwent surgery (curettage, en bloc resection and reconstruction with structural autograft, modular tumoral prostheses). 4 recurrences (7.54%) were recorded: in 3 patients who underwent curettage and cancellous bone autograft and one patient with resection and reconstruction with structural autograft technique. According to local functional grading systems, all functional results were good and very good. Osteoarthritis was recorded in 5 patients, all of them being treated by curettage and bone cement technique. In order to obtain optimal surgical results, a rigorous assessment of both investigations’ results and a correct classification of GCTB is needed.
