Background: Chemotherapy-induced alopecia (CIA) is a distressing adverse effect of many chemotherapy (CT) agents. New strategies for prevention of CIA have been studied. Scalp cooling has been reported to prevent CIA. We conducted a retrospective study aimed to assess the efficacy of scalp cooling in preventing CIA among women receiveing chemotherapy for breast cancer. Methods: Was included clinical data of breast cancer patients at the Oncoclinicas Group from July/2015 to March/2017. All patients were elected to use scalp cooling to prevent CIA. Cooling started 30 minutes before infusion and was maintained throughout the infusion of the treatment and extended for 90 minutes after infusion. Degree of hair loss was rated by nurse assessment using CTCAE v4.0 scale in grade zero (without alopecia), 1 (&lt;50%) or 2 (&gt;50%), digital photographs and clinical assessment. Assessments were made before each chemotherapy treatment and at a follow up visit between 3 weeks and 3 months after the completion of chemotherapy. Success was defined when there was G0 or G1 alopecia at the end of the treatment, and failure when finished with G2 alopecia and patient withdrawal due to alopecia. Results: 330 patients were included. 283 with localized breast cancer and 47 with metastatic disease. 188 patients (57.0%) completed all tratment with scalp cooling. 72 patients (21.8%) withdrew from cryotherapy for alopecia of any degreee, 51 patients (15.4%) gave up cryotherapy for complaints unrelated to alopecia and 19 patients (5.8%) had their treatment interrupted due to external factors (progression of disease, change of CT protocol, among others). Among patients who completed chemotherapy (n=188), the degree of alopecia at the end was G0 = 27, G1 = 138, G2 = 23. Thus, the overall success rate with cryotherapy was 63.5%. CT protocols initiated with doxorubicin and cyclophosphamide, followed by taxanes, presented a success rate of 50%. The combintation of docetaxel and cyclophosphamide showed success of 71.9%.

In addition to alopecia, headache and cold sensation were common reasons for cryotherapy withdrawal. Conclusions: Scalp cooling appears to be effective in preventing CIA among breast cancer patients who underwent chemotherapy. Studies involving a psychological approach to the expectation and experience of alopecia with cryotherapy and better management of pain are necessary to increase adherence to treatment.
