Non-Pharmacological Interventions for Managing the Symptoms of Depression in Women with Breast Cancer: A Literature Review of Clinical Trials.

Symptoms of depression represent a significant burden to patients with breast cancer, not only because of the psychological stress associated with their diagnosis, but also because of the adverse effects of its treatment. We reviewed the clinical trials examining the management of the symptoms of depression in breast cancer patients through different non-pharmacological interventions in different databases (PubMed, Embase, Scopus, and the American Psychological Association). Cognitive behavioural therapy, interpersonal psychotherapy or psychodynamic psychotherapy, as well as acceptance and commitment therapy have been effective in improving symptoms of depression in cancer patients with moderate to severe symptoms. Physical exercise, yoga, mindfulness, and support groups have been shown to benefit patients with mild depressive symptoms. These interventions not only showed positive results in interventions in women with breast cancer in terms of the symptoms of depression, but also highlighted their benefits for comorbid anxiety, stress, and poor sleep quality; moreover, it is suggested that these interventions should be leveraged to manage mental health issues in breast cancer patients. The molecular effects of these interventions, such as the reduction in inflammatory cytokines and cortisol levels, have seldom been reported and need further studies.
