  • Initial metastatic workup for all patients included computed tomography scan of the chest and bone scan.[ascopubs.org]
  • Physical examination usually reveals a soft-tissue mass at the primary tumor site, and laboratory workup is seldom remarkable except for elevations of alkaline phosphatase and lactate dehydrogenase, which have been reported with prognostic significance[ncbi.nlm.nih.gov]
