IntroductionPain is the most common symptom in patients presenting with spinal metastasis without neural compromise. Surgery, radiotherapy and vertebroplasty are all effective treatments alone or in combination. According to Boland et al. [1], early aggressive treatment may be considered to avoid cord compression. The aim of this study is to determine indications and strategy of surgical treatment related to the length of survival and to the risk of recurrence.
Materials and methodsOne hundred and seven patients were operated on for spinal metastasis without spinal cord compression. There were 54 women and 53 men, with a mean age of 58 (range 29-87). Neoplasm was revealed by spinal metastasis in seven cases. In the other cases, neoplasm had been known about for a mean period of 30 months (range 0-288 months). The primary tumour was predominantly lung neoplasm (37 cases), followed by breast neoplasm (30 cases), unknown (9 cases), kidney (8 cases), digestive tract (6 cases), others (17 cases). There were only two cases of primary prostate neoplasm. Back pain was the main symptom in all cases, with radiculopathy in 43 cases. Pyramidal irritation (Babinski sign, hyper-reAbstract Surgery in patients presenting with vertebral metastasis without neural deficit is controversial. A series of 107 patients (54 female, 53 male) were operated on at a mean age of 58. The metastasis was the first manifestation of the cancer in seven cases. In 100 patients, the cancer had been diagnosed 30 months earlier (average). Vertebral pain was present in all cases, with associated radicular pain in 43 cases. Pyramidal irritation without neural deficit was present in seven cases. The mean preoperative Karnofsky index was 64.7%. The mean preoperative Tokuhashi score was 8.6. The surgical approach depended on the topography of the metastasis. Ninety-three patients were dead at review, with a mean survival of 8 months. Seventeen patients underwent further spinal surgery, for local recurrence in nine cases, and for another spinal localization in eight cases, after a mean interval of 8 months. Recurrence occurred at the same level in all seven patients presenting with neural deficit at recurrence. Among ten recurrences without neural deficit, two were observed at the same level and eight were observed on another level. Surgery in vertebral metastasis without neural deficit results in substantial functional improvement, but does not increase the duration of life. For kidney metastasis, total vertebrectomy must be performed because of the risk of recurrence. For thyroid metastasis, total vertebrectomy is a good alternative to increase the efficacy of iodotherapy. In other cases, for patients with good general status, surgery must be adapted to the location of the involvement.
