Analysis of Tokuhashi Score

Cancer Clinical Trial

Official title: A Prospective Analysis of the Tokuhashi Score and Its Effectiveness in Guiding Treatment and Predicting Survival in Patients With Metastases Spread to the Spine

Status Terminated

Clinical Trial Summary

70% of all cancer patients develop some form of visceral (internal organs) or skeletal metastases (spread of disease). Approximately one third of cancer patients develop metastases to the spinal column. The prognosis once spinal metastases have been diagnosed and the most appropriate treatment still remains controversial. To date there is no one good diagnostic tool to predict survival and/or outcome after radiotherapy or surgical intervention.

Tokuhashi, et al, formulated and presented a preoperative scoring system to evaluate indications for surgery and predict outcome in patients with metastases to the spinal column. Six variables are measured to calculate this score: general medical condition, number of extraspinal metastases, number of vertebral metastases, status of metastases to the major internal organs, primary tumor type, and presence of a neurologic deficit. This scoring system has been gaining acceptance in literature. In 1998, Tokuhashi, et al, modified this scoring system by diversifying the tumor types into six categories. After a retrospective analysis Tokuhashi reported that patients with scores less than or equal to 8 will die of their disease within 6 months and those with scores of 12 or greater will survive an average of 12 months or more.

The purpose of this study is to determine 1) the Tokuhashi score's validity in predicting survival after developing spinal metastases, 2) the relationship of treatment on survival after detecting spinal metastases in relation to the Tokuhashi score. Patients will be enrolled into the study and followed prospectively for as long as possible regardless of intervention.

There will be three groups based on their Tokuhashi score, each group will require approximately 163 subjects statistically.
