INTRODUCTION

Accurate staging plays a critical role in the evaluation o f any malignancy be­ cause it has a pivotal role in determining therapy. Since stage and survival are strongly correlated, the prognosis is also determined by staging. Metastases to bone from any solid tumor are classified as distant, blood-born metastases and the tu­ mor is considered Stage IV.1 Documented bone metastases eliminates surgery as a curative option, generally mandating a chemotherapy approach occasionally with radiotherapy added for symptomatic lesions.
