BackgroundNeuropathic pain is present in at least 25-40% of people with cancer pain and is thought to be more difficult to control than other types of cancer related pain.ObjectiveThe purpose of this study was to explore differences in the experience of cancer patients who describe their pain using neuropathic descriptors compared to those who do not.MethodsA secondary analysis of data from 234 outpatients from a large NCI designated cancer center in west, central Florida was conducted to identify differences in pain, pain interference, symptoms, health related quality of life, and depression between the two groups.ResultsPatients with numbness, tingling, or electric-like sensations reported higher levels of current pain (p= .001), pain at its worst (p= .001), pain on average (p= .019), pain at its least (p= .008), and pain interference (p< .001). They reported problems with dizziness/lightheadedness significantly more often (p=.004) and also reported more severe problems with concentration (p=.047), poorer physical (p=.019) and mental health (p=.024), although no differences in depressive symptoms were found.ConclusionsThe results of this study indicate that cancer patients with numbness, tingling, or electric-like sensations have significantly higher levels of pain and pain interference, and lower health related quality of life than do patients without these symptoms.Implications For PracticeThese results highlight the ongoing need for research evaluating methods of treating neuropathic pain; education regarding assessment and management of neuropathic pain; and aggressive efforts to relieve neuropathic pain in oncology settings.
