Data collection
Data were uniformly collected, and the collectors were blinded to the grouping of the patients. Before the intervention, they explained the whole process of the prevention program, its purpose and its significance to the patients in detail. Then, they asked the patients to fill out an informed consent form, informing them of their right to withdraw from the trial at any time.A total of 3 time periods of patient data were collected for the study. Phase 1 (T0) collected baseline information from patients before the intervention; phase 2 (T1) was the patient's 3rd postoperative chemotherapy visit (9 weeks after surgery); and phase 3 (T2) was the 6th chemotherapy visit (18 weeks after surgery).
