This document summarizes a spine conference that discussed metastatic disease to the spine. It covered statistics on prostate cancer risk and mortality. It then presented a case study of an 80-year old man who was diagnosed with prostate cancer after undergoing spinal procedures for a fracture. The conference also discussed diagnostic studies for identifying unknown primary cancers, noting that CT scans often identify the origin in 75% of cases. Common primary cancers that metastasize to bone were listed as breast, prostate, lung, renal and hematopoietic tumors.
