Cancer Pain Management

Palliative Care

Multimodal control of nociceptive, neuropathic and incident pain in advanced malignancy.

Management

  • • WHO ladder: non-opioid → weak opioid → strong opioid, plus adjuvants at every step
  • • Regular modified-release opioid plus PRN breakthrough at 1/6 of the 24 h dose
  • • Neuropathic pain: amitriptyline, gabapentin, pregabalin or duloxetine
  • • Bone pain: NSAID, radiotherapy, bisphosphonate
  • • Always co-prescribe a stimulant laxative

Complications

  • • Opioid toxicity — myoclonus, pinpoint pupils, hallucinations, drowsiness
  • • Constipation
  • • Opioid-induced hyperalgesia

Clinical pearls

  • • Renal impairment: switch morphine to oxycodone or alfentanil
  • • Escalating dose with worsening confusion suggests toxicity, not undertreatment
