The aim of this project is to investigate the effect of triple prehabilitation led by nutritional optimization in liver cancer patients' surgery. It improves the preoperative nutritional status of cancer patients, reduces the incidence of early postoperative complications, promotes postoperative recovery, and improves the quality of patients' survival. Patients were randomized into experimental and control groups based on exclusion and inclusion criteria. Nutritional interventions and exercise and psychological interventions for patients. Interventions will continue for two weeks prior to surgery. Routine clinical blood tests will be performed at the time of enrollment, on the first day before surgery and on the first, third and fifth days after surgery. Enrolled patients were followed up by telephone or outpatient clinic at 1,3,6 months postoperatively.

Study subgroups: experimental group (nutritional optimization-led triple prehabilitation), control group (conventional triple prerehabilitation)
