Tailoring depression treatment for women with breast cancer
Factors unique to these patients help determine treatment strategies
Tricyclic antidepressants have been demonstrated to be effective in breast cancer patients. Side effects—notably anticholinergic effects—limit their use as antidepressants, especially when compared with SSRI treatment. In a study that randomly assigned 179 women with breast cancer to paroxetine, 20 to 40 mg/d, or amitriptyline, 75 to 150 mg/d, anticholinergic effects were almost twice as frequent in the amitriptyline group (19%) compared with paroxetine (11%).38 In a 4-week double-blind, placebo-controlled crossover trial of 15 breast cancer patients, amitriptyline significantly relieved neuropathic pain, but its adverse effects made most patients unwilling to use the medication regularly.39

Evidence supporting SSRI use in patients with breast cancer*
| Study | Design | Results |
|---|---|---|
| Navari et al, 200826 | 193 patients with newly diagnosed early-stage breast cancer were randomized to fluoxetine, 20 mg/d, or placebo for 6 months | Fluoxetine reduced depressive symptoms, improved quality of life, and led to higher completion of adjuvant chemotherapy and/or hormone therapy |
| Roscoe et al, 200527 | 94 women with breast cancer receiving at least 4 cycles of chemotherapy were randomized to paroxetine, 20 mg/d, or placebo | Paroxetine significantly reduced depression during chemotherapy |
| Kimick et al, 200628 | 62 women with early-stage breast cancer receiving the chemotherapy agent tamoxifen who reported hot flashes were randomized to sertraline, 50 mg/d, or placebo for 6 weeks | Sertraline was significantly more effective than placebo at reducing hot flashes |
| * Breast cancer patients who receive tamoxifen generally should be treated with an antidepressant that has minimal effect on cytochrome P450 2D6 metabolism, such as citalopram, escitalopram, venlafaxine, or desvenlafaxine SSRIs: selective serotonin reuptake inhibitors | ||
