Chemotherapy induced peripheral neuropathy (CIPN) is a numbness or tingling of the hands and feet that occur as a side effect of anticancer drugs including taxanes and platinum drugs. The effective treatments or preventive strategy are not established. Once it develops, symptoms persist for a long time and cause impairment in activity of daily living. Topical cooling is a preventive strategy for side effects of chemotherapy such as hair loss, oral microsites, and skin and nail disorder of the hands and feet. We conducted a clinical trial in breast cancer patients who received paclitaxel treatment to assess the effectiveness of cooling for CIPN prevention. In this study, the individual background factor was standardized using an intra-individual comparison design. In 40 subjects, frozen gloves and socks were applied on the dominant hand and foot from 15 minutes before the anti-cancer drug administration to 15 minutes after the end of administration (total 90 minutes) and compared with non-dominant hand and foot. As a result, clinically and statistically significant differences were observed for changes in tactile threshold evaluated by the monofilament test, subjective symptoms, and changes in dexterity evaluated by functional test. The current cooling system has not been well implemented in oncology field due to the lack of facility and human resources. To deliver this therapy broadly, it will be urgent to develop a medical cooling device that can provide safe and effective cryotherapy.
