A review of the neurological complications of breast cancer

Abstract

Conducting broad assessments of the main burden of breast cancer is the core factor for improving overdiagnosis and overtreatment of breast cancer patients as well as their survival rates. Breast cancer patients may experience neurological complications that cause devastating effects on them. Chemotherapy-induced peripheral neuropathy (CIPN) and neuropathic pain are two of the most reported complications. Objective: This study aims to review the neurological complications of breast cancer and the ways to control and treat them. Comprehensive searches were carried out about the keywords of Breast Cancer, Neurological Complications, and Breast Cancer Consequences. These keywords were searched through the most well-known databases of MEDLINE, PUBMED, Cochrane Library, Best Evidence, CancerLit, HealthSTAR, and LegalTrac. In this regard, 83 articles were chosen to be included in this study from 2010 to 2021. The identification and treatment process of neurologic syndromes are not easy. The main neurologic syndromes which the breast cancer patients face are opsoclonus myoclonus syndrome (OMS), encephalitis, sensorimotor neuropathy, retinopathy, cerebellar degeneration, and stiff-person's syndrome. CIPN and neuropathic pain are among the most prevalent side effects which are categorized as neurological complications and mainly seen 1 year after the management of breast cancer. Aiming to minimize the burden following the treatment of breast cancer, these complications should be diagnosed and treated accurately.
