Giant cell tumor of the spine

Six patients with giant cell tumor of the spine had surgery between 1981 and 1995. Three lesions were located in the scrum, two lesions were in the thoracic spine, and one lesion was in the lumbar spine. Preoperatively, all patients had local pain and neurologic symptoms. Two patients had cement implanted after curettage or intralesional excision of the sacral tumor; one patient had a local relapse. After the second curettage and cement implantation, the tumor was controlled. One patient with a sacral lesion had marginal excision and spondylodesis; no relapse developed. Two patients with thoracic lesions had planned marginal excision and spondylodesis; the margins finally became intralesional, but no relapse developed. One patient with a lumbar lesion had incomplete removal of the tumor and received postoperative irradiation. At the final followup (median, 69 months), five of six patients were disease-free and one patient died of disease progression. Two of the five surviving patients had pain after standing or neurologic problems. Although some contamination occurred, planning a marginal excision of the lesion seems beneficial for vertebral lesions above the sacrum. Total sacrectomy of a sacral lesion seems to be too invasive when cement implantation can control the lesion.
