Chemotherapy for breast cancer causes alopecia as a side effect. Some patients refuse chemotherapy because of alopecia, resulting in the omission of a standard therapy. It is believed that a scalp cooling device can prevent alopecia by promoting vasoconstriction of the scalp and reducing exposure of the hair root cells to anticancer agents. There are phenotypic differences of the efficacy of a scalp cooling device for alopecia. In fact, a Dutch scalp cooling registry reported that the success rate of scalp cooling was 51% in European women and 33% in Asian women. Therefore, we aimed to investigate the efficacy of scalp cooling device for chemotherapy-induced alopecia among Asian women with breast cancer.

Trial design

This is a phase II trialto evaluate the efficacy and safety of scalp cooling device for risk reduction of alopecia in women with stage I/II/III breast cancer treated with adjuvant/neoadjuvant chemotherapy in a single institute.

Eligibility criteria

Women diagnosed with Stage I to III breast cancer who are scheduled to receive preoperative or postoperative adjuvant chemotherapy containing anthracycline and/or taxanes are enrolled. Patients who have blood malignancies (leukemia, non-Hodgkin lymphoma, other systemic lymphoma), and cold allergy, are excluded.

Specific aims

The primary endpoint is the proportion of patients with Common Terminology Criteria for Adverse Events (CTCAE) grade 0-1 alopecia after the completion of all cycles of chemotherapy (success rate). Secondary endpoints are safety, quality of life, use of wig or cap, and success rates after the completion of all cycles of chemotherapy distinguished by anthracycline(AC) and taxane.

The cooling device is the Paxman scalp cooling system. Scalp cooling was performed from 30 mins before initiation until 90 mins (25 min for taxane) after chemotherapy. Pictures of the scalp were taken at the time of the initiation of each course.

Statistical methods

Successful treatment was defined as the presence of less than 50% of hair-loss area. The sample size was calculated using the Simon method, with a type I error of 10% (two-sided) and a study power of 80%.The expected success rate is 30%, with a threshold success rate of 10%, and the required number of patients was estimated to be 19.

Present and target accrual

Patient accrual was started in April 2018 and present accrual is 3. We plan to enroll a total of 20 patients in the trial.
