Waikakul S Backgound: To evaluate the relationship between local recurrence of giant cell tumor (GCT) after surgical treatments and
plain radiography, pathology grade and surgical procedures.
Material and Method: Patients with pathologically proven primary giant cell tumor of long bones, who underwent surgical
treatment in Siriraj Hospital between 1995 and 2007, were retrospectively reviewed. Plain radiographic findings were
reviewed by an experienced musculoskeletal radiologist without knowledge of the clinical history or pathologic results.
Specific attention on plain radiographic evaluations included site of tumor in long bone, total tumor volume, expansion of
cortex, breaking of cortex, and presence of pathological fracture. Patients with grade III tumor were excluded due to
malignant histology. Patients received treatments with amputation were also excluded due to no possibility of tumor recurrence.
Only patients who received surgical treatments with wide excision or curettage with cement were included in the present study.
Univariate analysis and Cox proportional hazard ratio was used to evaluate the influence of plain radiographic findings and
histology grade on risk of tumor recurrence.
Results: Seventy-four patients participated in this study and included 32 males (43%) and 42 (57%) females with a mean age
of 35 years (range 17 to 84). The median follow-up time was 3.2 years. Forty-eight patients (65%) underwent curettage with
cement or bone graft and 26 patients (35%) underwent wide excision. Sixty-three patients (85%) did not develop tumor
recurrence while 11 patients (15%) developed local recurrent tumor. Those occurred only in patients who underwent
curettage with cement or bone graft. None of the patients who underwent wide excision developed local recurrence. Median
of time after operation to recurrence was 3.5 years (range, 0.5 to 10.3 years). Local recurrence occurred in the distal femur
in five patients (45%), in the proximal tibia in five patients (45%), and in distal radius in one patient (9%). Risk of local
recurrence of GCT was not statistically different in patients with any abnormal features of plain radiography as well as
histology grade.
Conclusion: No radiographic findings and histological grade of GCT can predict tumor recurrence after curettage procedure.
Compared with wide excision, risk of local recurrence in patients that received treatment with curettage was significantly
higher. However, the choice of treatment should be balanced between preserving maximal joint function and risks of tumor
recurrence.
