Abstract

Purpose Survival after metastatic cancer has improved at the cost of increased presentation with metastatic spinal disease. For patients with pathologic spinal fractures and/or spinal cord compression, surgical intervention may relieve pain and improve quality of life. Surgery is generally considered to be inappropriate if anticipated survival is, 3 months. The aim of this international multicenter study was to analyze data from patients who died within 3 months or 2 years after surgery, to identify preoperative factors associated with poor or good survival, and to avoid inappropriate selection of patients for surgery in the future. Patients and Methods A total of 1,266 patients underwent surgery for impending pathologic fractures and/or neurologic deficits and were prospectively observed. Data collected included tumor characteristics, preoperative fitness (American Society of Anesthesiologists advisory [ASA]), neurologic status (Frankel scale), performance (Karnofsky performance score [KPS]), and quality of life (EuroQol five-dimensions questionnaire [EQ-5D]). Outcomes were survival at 3 months and 2 years postsurgery. Univariable and multivariable logistic regression analyses were used to find preoperative factors associated with short-term and long-term survival. Results In univariable analysis, age, emergency surgery, KPS, EQ-5D, ASA, Frankel, and Tokuhashi/Tomita scores were significantly associated with short survival. In multivariable analysis, KPS and age were significantly associated with short survival (odds ratio [OR], 1.36; 95% CI, 1.15 to 1.62; and OR, 1.14; 95% CI, 1.02 to 1.27, respectively). Associated with longer survival in univariable analysis were age, number of levels included in surgery, KPS, EQ-5D, Frankel, and Tokuhashi/Tomita scores. In multivariable analysis, the number of levels included in surgery (OR, 1.21; 95% CI, 1.06 to 1.38) and primary tumor type were significantly associated with longer survival. Conclusion Poor performance status at presentation is the strongest indicator of poor short-term survival, whereas low disease load and favorable tumor histology are associated with longer-term survival.

6. Respiratory abnormalities due to craniovertebral junction compression in rheumatoid disease

Abstract

Respiratory insufficiency appears common in patients with rheumatoid disease-related atlantoaxial dislocation. Rheumatoid disease is a general term for diseases that involve inflammation of the joints, ligaments or muscles. Atlantoaxial refers to the first and second cervical vertebrae. Twelve patients with atlantoaxial dislocation related to rheumatoid disease were examined. Patients with deformations of the medulla, the part of the brain that extends to the spinal cord, had abnormal nighttime blood gas measurements. Four patients with severe spinal cord compression had evidence of spinal cord disease. Three of these patients had mildly abnormal nighttime blood gas measurements. It appears that respiratory insufficiency may occur in patients with atlantoaxial dislocation without symptoms and without spinal cord compression.
