Abstract
Pain is the most feared symptom for patients diagnosed with cancer. Although our understanding of cancer pain and its management has greatly improved in the past decade, an unacceptably large proportion of patients still do not receive adequate pain relief. Before commencing any form of treatment, patients must receive a thorough assessment in order to define the pain, causes and severity. The recommendations for progressing a patient from step 2 to step 3 of the WHO analgesic ladder are discussed here as well as the choice of strong opioid substitution. An overview of the benefits of considering alternative routes of administering strong opioids, such as the transdermal delivery of fentanyl (TTS fentanyl), and the use of opioid substitution in patients intolerant to the adverse effects of morphine are also included. Finally, newer approaches to relieving refractory pain, such as neuropathic and bone pain, are considered.
