title: Clinical effects of three surgical approaches for a giant cell tumor of the distal radius and ulna.
abstract: The aim of the present study was to assess the curative effects of three surgical approaches for a giant cell tumor (GCT) of the distal radius and ulna. A total of 27 patients with GCT on distal radius and ulnas (7 and 20, respectively), confirmed by biopsy, were treated with individualized treatment regimens, according to the Campanacci's grade system: i) Curettage plus inactivated tumor bed and allogeneic bone graft/bone cement augmentation for Campanacci's grade I GCT of the distal radius and ulna (Group A); ii) simpleen blocresection for Campanacci's grade II and III GCT of the distal ulna (Group B); iii)en blocresection and reconstruction with non-vascularized fibular autograft/allogeneic bone graft for Campanacci's II and III GCT of the distal radius (Group C). Postoperative recurrence and complications were recorded. The Musculoskeletal Tumor Society Score was used to assess functional results. The mean follow-up time was 25 months (range, 9-125 months). A total of 3 patients exhibited tumor recurrence at 9, 11 and 15 months following surgery (1 case succumbed to pulmonary metastasis at 27 months). Overall, the incidence of the postoperative recurrence of the GCT of the distal ulna and radius were 14.3 (1/7) and 10% (2/20), respectively, with a statistical P-value of 0.762. No statistically significant difference was observed regarding the incidence of the postoperative recurrence, postoperative complications and MSTS results among the three surgical approaches for the GCT on distal ulna and radius (all P>0.05). However, statistically significant differences were noted when the incidence of the postoperative recurrence of curettage (Group A) was compared with that ofen blocresection (Groups B and C) (P=0.024). In conclusion, in order to achieve the best clinical effects for patients with GCT on distal radius and ulna, individualized treatment regimens must be designed according to the different Campanacci's grades and tumor locations.
