Background Giant-cell tumor (GCT) of bone is a common primary benign tumor with high local recurrence and potential distant metastasis or malignant transformation. We haveinvestigated the clinical behavior of recurrent GCT of bone in the extremities. Methods We retrospectively reviewed 110 patients with recurrent GCTs of bone in the extremities treated by the Eastern Asian Musculoskeletal Oncology Group. The factors that affected the number of recurrences and distant metastasis were analyzed. Results The median interval between initial surgery and the first recurrence of GCTwas 16 months (2-180 months). All patients received additional surgery for first recurrence. Twenty-five patients had a second recurrence and 6 patients had a third recurrence. The mean interval between theinitial surgery and the first recurrence correlated withthe eventual number of recurrences-14.1 months for the repeated recurrence groups (two and three recurrences) and 28.3 months for the single recurrence group (p = 0.016). Campanacci grade did not correlate with repeated recurrence (p = 0. 446). The venue of the initial surgery did not correlate with recurrence but did affect preservation of the adjacent joint (chi-squared test; p =0.046). Campanacci grade II and III also correlated withsacrifice of the adjacent joint (p = 0.020). The incidence of lung metastasis and malignant transformation were 7.5% (8 out of 107 patients) and 2.7% (3 out of 110 patients), respectively. Repeat recurrence was associated with lung metastasis (p = 0.018). © The Japanese Orthopaedic Association 2011.
