carcinoid

carcinoid tumour

introduction

  • neuroendocrine tumour derived from primitive stem cells in the gut wall but can arise elsewhere
  • high potential for metastasis

clinical features

investigations

  • 24 hour urinary 5-HIAA levels are usually elevated
  • fasting plasma 5-HIAA assay is more convenient than the 24hr urine collection
  • if either of the above are positive, consider imaging such as:
    • octreotide nuclear med scan
    • PET scan at an oncology centre (however in Australia, not covered by Medicare unless known tumour)
