'Scalp cooling device' will be used to prevent alopecia during chemotherapy regimen infusion.

'Cold cap' will be used to prevent alopecia during chemotherapy regimen infusion.

Scalp cooling was initiated 30 minutes prior to each chemotherapy cycle, with scalp temperature maintained at 3°C (37°F) throughout chemotherapy and for 90 minutes to 120 minutes afterward. Temperature of scalp cooling system can be controlled constantly, the effect of reducing scalp temperature maybe better and patient tolerance maybe better. Meanwhile, there is a higher likelihood of hair retention due to a tight fit in scalp cooling system.

To compare the effects of scalp cooling system and chemical cold cap on the prevention of chemotherapy-induced alopecia in breast cancer patients undergoing neoadjuvant chemotherapy containing anthracycline followed paclitaxel. To assess hair status, a total of three photographs of patients'hair in the both groups were taken by study personnel before the start of first chemotherapy cycle, within 2 days before the start of paclitaxel chemotherapy and within 1 week after the last chemotherapy cycle. Photographs captured hair from the top of head. Patients assessed and estimated the percentage of hair loss using WHO classification of acute and subacute toxicity of anticancer drugs. Success was defined as WHO criteria alopecia grade I (<25% hair loss) or grade II (25%-50% hair loss). Failure was defined as WHO criteria alopecia grade III (>50% hair loss) or grade IV. The primary efficacy end point was assessed by clinicians who were independent.

To compare the effects of scalp cooling system and chemical cold cap on the quality of life. Quality of life was measured using the European Organization for Research and Treatment of Cancer Breast CancerSpecific Quality of Life Questionnaire-Core 30（EORTC QLQ-C30） administered at baseline and at the time of the last chemotherapy cycle.
