Conservative non-pharmacological treatments for chemotherapy-induced peripheral neuropathies in women treated for breast cancer: a systematic review.

Over the last few decades, the use of neo/adjuvant therapies has significantly increased the number of breast cancer survivors who experience chemotherapy-induced peripheral neuropathy (CIPN). To date, few, low-efficacy, pharmacological remedies exist to manage this side effect. For this reason, alternative treatments are increasingly being investigated as possible strategies to prevent or promote faster recovery from CIPN. In this review we aimed to provide an overview of the literature evidence regarding all the non-pharmacological and rehabilitative interventions for patients affected by CIPN secondary to breast cancer care. A comprehensive literature search was conducted on PubMed, Scopus and Web of Science and included a total of 1895 patients (1528 with breast cancer) with a wide range of CIPN (motor, sensory and autonomic neuropathies) and chemotherapy treatments (e.g., Taxanes, Platins, Vinca alkaloids or monoclonal antibody drugs). Of the initial 1108 hits, only 25 studies - describing different treatment modalities for peripheral neuropathies - were finally included in the qualitative synthesis. Most studies focused on acupuncture, physiotherapy, cryotherapy, and yoga. There is still controversial evidence on conservative non-pharmacological interventions for the management of CIPN symptoms. We believe however that moderate exercise, as well as all types of stress reducing activities like sport, yoga and mindfulness, should be encouraged in cancer patients for their positive effect on global physical and psychological health. Further studies of higher methodological quality are needed to determine the best conservative approach to CIPN.
