PurposeTo compare pain-related treatment satisfaction, patient-perceived side effects, functioning, and well-being in patients with advanced cancer who were receiving either transdermal fentanyl (Duragesic, Janssen Pharmaceuticals, Titusville, NJ) or sustained-release oral forms of morphine (MS Contin, Perdue Frederick Co, Norwalk, CT, or Oramorph SR, Roxanne Laboratories, Columbus, OH).Patients And MethodsA total of 504 assessable cancer patients participated in this cross-sectional, quality-of-life study. Relevant elements of four validated scales were used--the Functional Assessment of Cancer Therapy-General (FACT-G) scale, the Brief Pain Inventory (BPI), the Medical Outcomes Study (MOS) questionnaire, and the Memorial Symptom Assessment Scale (MSAS)--as well as original scales that were developed and validated for this study.ResultsThe majority of patients in both treatment groups had late-stage (IV/D) cancer. Patients who received transdermal fentanyl were more satisfied overall with their pain medication than those who received sustained-release oral forms of morphine (P = .035). Fentanyl patients also experienced a significantly lower frequency (P < .002) and impact (P < .001) of pain medication side effects. These results occurred despite the fact that cancer patients who received fentanyl were significantly older (P < .001) and had significantly lower functioning and well-being scores (P = .001). Measures of pain intensity, sleep adequacy, and symptoms demonstrated no significant differences between treatment groups.ConclusionThese data suggest that patients are more satisfied with transdermal fentanyl compared with sustained-release oral forms of morphine. A lower frequency and reduced impact of side effects with transdermal fentanyl may be one reason cancer patients who receive fentanyl are more satisfied with their pain management.
