Both hands and feet received cryotherapy, and the frequency was once every three weeks. Each cycle was 90-150 minutes, and the cycle was performed 4-8 times. The instrument included EPRTC QLQ-CIPN20, PNQ, and EORTC QLQ-C30. After 12-32 weeks, the cryotherapy received qualitative interviews to collect experience and perceptions. Quantitaitve data were constructed and analyzed with SPSS 20.0 version, and Chi-square test was used to detect the incidence of CIPN after three months.
