Whereas most pain due to cancer can be relieved with relatively simple methods using oral analgesics, as suggested by WHO guidelines, some patients may have difficult pain situations that require more complex approaches. It is estimated that 10-20 % of cancer patients suffer from pain that is not easily relieved. There are a number of factors that may reduce the efficacy of opioids in the management of cancer pain. Neuropathic pain (NP) and breakthrough pain (BP), especially of the incident subtype, have been identified as challenges for clinicians. In several prognostic studies, these two mechanisms were associated with limited positive outcomes compared with other syndromes. Opioid-induced hyperalgesia has recently been described as representing a challenge for physicians in the clinical setting. The global response to opioids, including the development of adverse effects, typically varies by individual and is likely genetically determined. Moreover, clinical evidence suggests that different opioids may produce different effect profiles, and so it is more appropriate to consider the response to each individual opioid rather than general opioid response. This paper will review both pharmacological and procedural mechanisms and treatments of these difficult pain syndromes.

A 66-year-old female patient was diagnosed with hepatocellular carcinoma accompanied by neuropathic pain induced by a metastatic tumor that compromised root and spinal canal. Although her pain was relieved following medical treatment, breakthrough pain occurring 1-2 times a day was still distressing. Neuropathic pain in her right lower limb caused discomfort and irritability and decreased her quality of life. We had limited options to adjust her prescription drug regime, due to the side effect of these drugs. Although acupuncture therapy was only performed at her home once a week, the efficacy was outstanding. The patient did not report any further instances of breakthrough pain, and she did not require additional bolus morphine. She could comfortably live in her familiar surroundings with her family and did not require any emergency room visits or admission into the hospital during the last month of her life. She had excellent quality of life in the terminal period of her life, and could even participate in a family function during this time. The present case report suggests that acupuncture may have a role in treating neuropathic pain induced by bone metastasis in patients with advanced cancer across clinical and in-home settings.
