Abstract
Cancer-related neuropathic pain (CNP) requires therapy involving multiple pharmaceuticals, including anticonvulsants and antidepressants; however, strong evidence to support this practice is limited. This study is a cross-sectional questionnaire-based survey. As the standard dose of adjuvant analgesics for CNP refractory to opioid therapy is not clear, the purpose of this study is to clarify the opinions of specialists about the usage of duloxetine and pregabalin for patients with CNP refractory to opioid therapy. Two hundred and eight certified palliative care specialists were surveyed and a total of 87 (42%) responses were analyzed. Twenty-five percent of specialists had considered increasing duloxetine doses up to 60 mg/day and 58% had considered increasing pregabalin doses up to 300 mg/day for CNP refractory to opioid therapy. However, 23% of the specialists succeeded in increasing duloxetine doses up to 60 mg/day and 17% in increasing pregabalin doses up to 300 mg/day, respectively.
