Effectiveness of Cryotherapy Combined With Compression Therapy for Preventing Chemotherapy-induced Peripheral Neuropathy

All HER-2 negative breast cancer patients received neoadjuvant chemotherapy with four cycles of dose-dense epirubicin and cyclophosphamide (ddEC) followed by four cycles of dose-dense albumin-paclitaxel (ddT). The patients were randomly assigned in a 1:1 ratio to receive cryotherapy combined with compression or no intervention. The primary endpoint was incidence of grade 3 and higher peripheral neuropathy as assessed by NCI-CTCAE V5.0.

Inclusion criteria
