Abstract
Aims: Evalutation of the different surgical option (simple decompression and stabilization vs. intralesional excision vs. en bloc resection) in the treatment of spinal metastases from RCC. Methods: Sixty-one cases in 56 patients with symptomatic spine metastases secondary to Renal Cell Carcinoma (RCC) were treated between 1991 and august 2002. The metastases was located in 43 cases in the lumbar spine, in 23 cases in the thoracic spine and in 4 cases in the cervical spine. Twelve patients were submitted only to radiation therapy. Different procedure was done in the remainder cases: in 16 cases a palliative procedure, in 22 cases a curettage and in 6 cases a en bloc resection. Radiation therapy (RTR) was performed after surgery in 37 cases, Selective Arterial Embolization (SAE) in 29 cases, Chemotherapy (different protocols) in 5 cases and Immunotherapy (IL 2+IFN) in 22 cases. Results: Fifteen patients only were followed for 24 months at least. Of 3 patients submitted to palliative surgery, 1 is alive without disease (NED) at 28 months from treatment, while 2 are dead at 24 and 27 months. Of 10 patients submitted to curettage 5 are continuous disease free (CDF) (24 to 44 months; average: months); 1 is NED at 56 months, 2 are alive with disease (AWD) at 24 and 25 months and 2 are dead after 40 and 68 months. Two patients were submitted to en bloc resection and are CDF at 24 and 30 months after tretament. Conclusions: The treatment of spine metastases of RCC is multidisciplinary: the eligibility of patients to en bloc resection both on the basis of general conditions and local tumor expansion is critical for the local control of the disease. If en bloc resection is not feasible, combination of SAE, complete intralesional excision, RTR, Immunotherapy seem to be the most appropriate treatment.
