Local recurrences after curettage and cementing in long bone giant cell tumor

Abstract

Background: Giant cell tumor of bone (GCT) is a benign lesion with great propensity for local recurrence. This study aimed to analyse the rates of local recurrence and its possible predisposing factors in Campanacci’s Grade III and II GCT of long bones following intralesional curettage and bone cementing. Materials and Methods: 32 cases of either sex with Campanacci’s Grade II (n= 14), and Grade III (n=18) with intact articular surface, operated between 1995 and 2007 in form of intralesional curettage and bone cementing were studied. All the cases were followed up for 2.5–12 years (mean, 6.5), after primary treatment. The mean age at operation was 32.4 years (range, 18.5–40 years). The proximal tibia was involved in 13 cases (40.6%), followed by distal femur (n=11)34.4% distal tibia (n=3) 9.4%, proximal femur (n=2) 3.2% and distal radius (n=3) 9.4%. Results: Eleven patients (34.4%) had local recurrence, of which eight were of Campanacci’s Grade III. The mean recurrence time was 14 months (range, 3-34 months). The two-year recurrence-free survivorship was 71.9% (n=23/32). Post-recurrence mean follow-up was 4.2 years (range, 2–6.5 years). Conclusion: We observed higher rate of local recurrence with Campanacci’s Grade III GCTs. We recommend selective use of this procedure in Grade III lesions, particularly with extensive soft tissue involvement.
