Abstract :
BACKGROUND: One of the most important selection criteria for spinal metastases surgery is life expectancy and the
most important system for this prediction has been proposed by Tokuhashi. The aim of this study was to evaluate
predictive value of the Tokuhashi score for life expectancy in Iranian patients with spinal metastases one year after
diagnosis.
METHODS: From February 2007 to March 2009, of 180 patients suffering spinal metastatic tumors, 71 patients were
excluded. This left a study population of 109 patients with known malignant metastases to spine (56 females and 53
males; mean age, 57 ± 12 years). Tokuhashi revised evaluation system for the prognosis of metastatic spinal tumors was
used for all patients. The survival period predicted by this system for the prognosis and the actual survival period after 1
year follow up were evaluated.
RESULTS: The predicted survival according to Tokuhashi prognostic scoring system was less than 6 months in
38(34.9%) patients, 6-12 months in 39(35.8%) patients and 1 year or more in 32(29.4%) patients. 39 (35.8%) patients
died at first six-month of the follow up, 28(25.7%) patients at the second six-month period and 42(38.5%)
patients were alive at the end of the year. There was no significant difference between predicted and actual survival
time (p = 0.116).
