Real-world data on usage of scalp cooling for chemotherapy associated alopecia in the United States.

Abstract

e18739 Background: Hair loss is a well-known side effect of chemotherapy. The Paxman Hair Loss Prevention System, a scalp cooling device, has been shown to be effective in reducing chemotherapy induced alopecia in patients receiving chemotherapy (Nangia, JAMA, 2017). The National Comprehensive Cancer Network and the European Society for Medical Oncology guidelines have recommended scalp cooling as category 2A and 2B options, respectively. Methods: The real world use of scalp cooling using the Paxman device, as documented by orders through the Paxman Hub during the years of 2017-2020 was summarized. Descriptive statistics were used to summarize demographics and utilization. Results: Data from 6649 patients who used scalp cooling were reviewed. Patients with breast cancer were the most common users of scalp cooling (78%, n=5197) followed by gynecology (12%, n=775), gastrointestinal (3%, n=201), lung (1%, n=81) and genitourinary (1%, n=52). The majority of patients were between the ages of 45-65 (55%), followed by 65-74 (18%), older than 75 (5%), and 25-44 (2%). Average number (#) of cycles of cooling completed was 6.53 (range of average # of cycles 4.50-12). Scalp cooling with this device was commonly used in 39 out of 50 states. Conclusions: This is the largest report of scalp cooling usage in the real world setting in the USA, including scalp cooling usage in older adults. Uptake of scalp cooling across various cancers has not been uniform and this deserves further study.
