Abstract

Progress in oncological therapy within the last decade has enhanced the survival time of patients suffering from tumorous osteolyses of the spine. While the necessity of surgical intervention is often settled by acute clinical symptoms, the extent of surgery is certainly co-determined by the patient's expectations and the time of survival to be expected. We therefore developed a specific tumor algorithm for operations on the spine with special emphasis on prognosis and the attainable quality of life. The results of 154 patients with tumorous osteolyses of the thoracic and lumbar spine, who were treated according to our algorithm, underline the unequivocal advantages of initially posterior procedures.

In plain English

This article from Ulm, Germany, is about spinal tumor surgery, not asbestos. Urgent cases were operated on first from the back (posterior stabilisation), while patients with a free spinal canal and a stable spine might have only a biopsy. A front operation was added if expected survival exceeded 6 months, and 12 patients had both at once. The authors reported on 154 patients (84 men, 70 women) operated on from January 1985 to June 1996. Patients with malignant tumors survived a mean of 16.4 months. There were 23 complications in 195 operations (11.8%), or 15.4% counting the seven deaths within 30 days. Fifty-nine patients with nerve symptoms before surgery improved, and nine worsened. One example was a 60-year-old man whose L5 metastasis the text calls "pleuramesothelioma" but whose figure caption calls it adenocarcinoma of unknown origin. He lived 5 months after surgery, still walking, with less pain. The authors concluded their plan fits their aim of improving patients' quality of life. They said prospective studies must confirm its efficiency, and that it is unclear whether longer survival comes from surgery.

What the study did and found

• Design: Description of the authors' surgical treatment algorithm for spinal tumors, with a case series of patients treated at their clinic and three illustrative patient examples
• Who was studied: 154 patients (84 men, 70 women) with tumorous osteolyses of the spine, mean age 52.7 years (range 7.4 to 85.4 years), operated on at the orthopaedic department of the University of Ulm, Germany, from January 1985 to June 1996. 131 had malignant lesions and 23 had benign lesions. 104 had a posterior approach only (group 1). 20 had a second anterior procedure with alloplastic vertebral body replacement (group 2). 12 had an anterior approach with autogeneic replacement (group 3). 18 had biopsy alone. In 12 cases where the tumor histology was already known before surgery, posterior and anterior surgery were done at the same time.
• Exposure: Not applicable. The article studies surgical treatment of spinal tumors, not asbestos or any fiber exposure. No asbestos exposure is mentioned, including for the patient described as having pleuramesothelioma.
• Main results:
  • In the algorithm, patients with a free spinal canal and stable vertebrae might have a biopsy as the only initial surgical step. Immediate operations were always done from the back.
  • Among patients with a malignant tumor, mean survival time was 16.4 months (range 0.1 to 80.4 months)
  • Seven patients died within the first month after surgery. The authors reported this as a 30-day mortality rate of 4.5% in patients with malignant disease.
  • Mean survival was 13.9 months in patients with posterior stabilisation only, 18.2 months with additional anterior alloplastic vertebral body replacement, and 41.7 months with additional anterior autogeneic replacement. Patients were assigned to these groups according to their expected survival time.
  • 23 complications occurred in 154 patients with 195 operations, a complication rate of 11.8%. The rate would be 15.4% if the 30-day deaths are counted as complications.
  • 59 patients with preoperative neurological symptoms improved after surgery, including 21 with incomplete paraplegia. 9 patients deteriorated in follow-up. All 53 patients without preoperative neurological symptoms remained unchanged.
  • Case example: the text describes a 60-year-old man with a metastasis of a highly malignant pleuramesothelioma at level L5. He survived 5 months after posterior stabilisation, kept his walking ability with reduced pain, and died of multiloculated metastatic spread. The caption of the cited Figure 3 describes the same patient's tumor as an adenocarcinoma of unknown origin.
• The authors' conclusion: The authors held that operative treatment should be dedicated to improving the patient's quality of life. They concluded that their tumor algorithm, with little operative stress and morbidity and high initial stability, serves this philosophy. They added that prospective studies will have to confirm its efficiency.
• Limitations the authors state:
  • The authors stated it is not clear whether prolonged survival is due to surgery, improved diagnostic methods, or progress in radio- and chemotherapy
  • The authors stated that prospective studies are still needed to confirm the algorithm's efficiency
  • The average hospital stay of 47 days could not be broken down further because of the mixed pattern of cases
