Prevalence of Spinal Metastasis in Neurosurgical Procedures: A Descriptive Study
نویسندگان
چکیده
Objective: This study sought to identify the prevalence of operations for spinal epidural neoplastic metastases relative to other spine and neurosurgical operative procedures. Methods: This study was descriptive and involved a retrospective review of data collected from patients who underwent neurosurgeries between February 1997 and January 2015 at a single quaternary hospital. The examined population was distributed across five descriptive categories to perform numerical distributions among neurosurgical operative procedures. Results: A total of 12,802 neurosurgical procedures were identified. These procedures were classified as follows: Skull and brain, 11,192 (87.42%); spinal column and spinal nervous tissue, 1462 (11.42%); and peripheral nerves, 148 (1.16%). Surgical procedures for the 1462 (100%) cases of spinal column and spinal nervous tissue diseases were distributed by nosology as follows: Degenerative intervertebral disk and spondylosis, 768 (52.54%); neoplastic, 279 (19.08%); traumatic, 221 (15.11%); congenital, 163 (11.14%); infectious and inflammatory, 27 (1.85%); and vascular, 4 (0.28%). With respect to the distribution of the 279 (100%) surgical procedures for spinal column and spinal nervous tissue neoplastic diseases, 124 (44.44%) procedures were for intradural neoplasms, and 155 (55.56%) procedures were for epidural spinal column neoplasms. The 155 (100%) operations for epidural neoplastic diseases were distributed into two groups: Primary epidural neoplasms, 42 (27.10%); and secondary epidural neoplasms, 113 (72.90%). Spinal column epidural neoplastic metastases (secondary neoplasms) represented 0.88% of the 12,802 neurosurgical procedures. Conclusions: Surgical procedures for spinal metastasis are uncommon with respect to all neurosurgical operative procedures. Trend analysis reveals an unchanging trend of prevalence for these procedures.

Background and Purpose: Hospital admission for surgery is an important event for patients. Canceling surgical procedures produce several unpleasant results for patients such as waste of time, including payment. The aim of this study is to identify the prevalence and causes of canceling surgical procedures, in order to achieve problem solving methods. Materials and Methods: This is a descri...
متن کاملThe workload of neurosurgeons: implications of the 1987 practice survey in the USA.
The number of neurosurgeons per million population is much lower in Europe than in the USA, where the point prevalence of neurosurgeons doubled between 1963-87. Results of a 1987 survey of USA neurosurgical practice show that surgery filled 25% of total time in professional activity. Of all cases treated, 64% were spinal disorders and 24% were intracranial disorders. Use of a relative value sca...
متن کاملTwo separate episodes of intramedullary spinal cord metastasis in a single patient with breast cancer.
Intramedullary spinal cord metastases are very rare. Patients with breast cancer as the primary source of intramedullary spinal cord metastases tend to do better than other types of cancer. We report the very unusual case of a woman with breast cancer who had two separate episodes of intramedullary spinal cord metastasis.

A 60-year-old patient with testicular seminoma was referred for F-18 FDG PET/CT Study to evaluate recurrence. In addition to hypermetabolic cervical, mediastinal and hilar lymph node tumoral metastases, segmental intense FDG uptake along the lumbar spinal cord suggestive of tumoral metastasis was noted which quite an unusual presentation is. At the time of PET study the patient was symptomless...

Background: Life expectancy of patients with spinal metastasis is an important factor to manage these patients. Tokuhashi is a scoring system which was the sum of the points of six items: 1.general condition, 2. number of extraspinal bone metastasis, 3. number of metastasis in the vertebral body, 4. presence or absence of metastasis to major internal organs, 5. site of the primary lesion, 6. ...
