Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The metastasis is the spread of cancer from one part of the body to another. Two-thirds of patients with cancer will develop bone metastases. Breast, prostate and lung cancer are responsible for more than 80% of cases of metastatic bone disease. A spinal metastasis may cause pain, instability and neurological injuries.

* The spine is the most common site of bone metastasis . It is estimated that over the 10% of patients with cancer will develop a symptomatic spinal metastasis . Algra et al. suggest that the initial anatomic location of metastases within vertebrae is in the posterior portion of the body.
* Spinal metastases are the most common tumors of the spine, comprising approximately 90% of masses encountered with spinal imaging. Within the spinal column, metastasis is more commonly found in the thoracic region, followed by the lumbar region, while the cervical region is the least likely place professionals find metastasis .
* Spinal metastases most commonly affect the vertebral bodies of the spinal column, and spinal cord compression is an indication for surgery. Commonly, an open posterior approach is employed to perform a transpedicular, costotransversectomy or lateral extracavitary corpectomy. Because of the short life expectancies in patients with metastatic spinal disease, decreasing the morbidity of surgical treatment and recovery time is critical.
* At present, both surgical and nonsurgical treatments are used for the treatment of spinal tumors, however, treatment outcome is dependent on various factors, such as patient age, overall health of the patient .
* When treating patients with vertebral metastases, surgical strategy is mainly based on life expectancy, primary site of tumor, and staging. This helps determine which patients will benefit from surgery and the type of procedure. Tokuhashi developed a score to determine life expectancy in order to facilitate the treatment modality decision .
* Vertebral corpectomy refers to the removal of one or more vertebral bodies from the spine, as well as the intervertebral discs above and below the surgical level.

Corpectomies may be accomplished through a multitude of approaches. Posterior approaches have been associated with less intraop- erative blood loss, complications, shorter operative time, and better pul- monary function post-operation compared to anterior approaches .
