Managing vasomotor symptoms in women after cancer.

Women with estrogen-sensitive cancer or survivors of these neoplasms are generally not candidates for systemic menopausal hormone therapy or tibolone for the treatment of bothersome vasomotor symptoms (hot flashes or night sweats). However, menopausal symptoms negatively affect quality of life and need to be addressed by clinicians. For mild vasomotor symptoms, optimizing lifestyle changes or mind-brain behavior may be sufficient. For women with moderate to severe vasomotor symptoms unresponsive to these measures, non-hormone pharmacologic therapy may be needed. Randomized controlled trials have shown efficacy for vasomotor symptoms with selective serotonin reuptake inhibitors (paroxetine, citalopram, and escitalopram) and serotonin-norepinephrine reuptake inhibitors (venlafaxine and desvenlafaxine), as well as gabapentin, pregabalin, and clonidine. Therapies in development include neurokinin B inhibitors (neurokinin 3 receptor), stellate ganglion blockade, and a natural estrogen, estetrol. Individualizing therapy is important. As the physiology of menopausal hot flashes becomes better understood, it will drive development of future non-hormone pharmacotherapies.
