The effect of fluoxetine on anxiety and depression symptoms in cancer patients.
Little has been done to study the effectiveness of antidepressants in controlling anxiety/depression in a population of cancer patients. A double-blind placebo-controlled study was therefore designed to assess the effectiveness of 20 mg fluoxetine. Of 115 cancer patients who fulfilled entry criteria for levels of distress, 45 patients were randomized to a fluoxetine treatment group (FA) and 46 patients to a placebo group (PA) after a 1-week placebo period designed to exclude placebo responders. The Montgomery and Asberg Depression Scale (MADRS), the Hamilton Anxiety Scale (HAS), the Hospital Anxiety and Depression Scale (HADS), the Revised Symptom Checklist (SCL90-R) and the Spitzer Quality of Life Index (SQOLI) were used to assess the efficacy of fluoxetine. The response rate, defined by a HADS score lower than 8 after 5 weeks of treatment, was not significantly higher in the FA group (11%) compared to the PA group (7%). Compared to the PA group, patients in the FA group showed a significantly greater decrease in SCL90-R mean total score after 5 weeks, but not a greater decrease in HADS mean score. No difference between the two groups was found in observer-reported assessments (MADRS, HAS and SQOLI). Significantly more drop-outs were observed in the FA group (n = 15) than in the PA group (n = 7), although the frequencies of side-effects were not significantly different.
