简要总结
Colon cancer and primary liver cancer are common malignant tumors with low survival rate worldwide, and unresectable primary liver cancer and colon cancer liver metastases have worse prognosis. End-stage liver disease is equated with advanced liver disease, liver failure and decompensated cirrhosis because they are generally irreversible. Liver transplantation is a treatment option for the above-mentioned patients and is expected to improve the prognosis of the patients, but the biggest problem faced by such patients is the shortage of donor livers. Recently, a new surgical modality, resection and partial liver segment 2-3 transplantation with delayed total hepatectomy (RAPID), can greatly alleviate these problems.Based on clinical surgical experience, our center proposes and designs a clinical study of adjuvant liver transplantation combined with two-stage hepatectomy in the treatment of patients with unresectable primary liver cancer, colorectal cancer liver metastases, or end-stage liver disease. By improvement of RAPID operation, the safety and efficacy of this treatment method in patients with those disease were evaluated.

结局指标
主要结局
Three-year overall survival rate after surgery
时间窗: 3 years after the second liver resection
After the second liver resection, patients were followed up through outpatient clinics and telephone (interval: once a month for a total of three years). The end point of follow-up was the death of the patient or survival after three years of follow-up. After reaching the end point of follow-up, the overall survival rate was analyzed by drawing survival curves.
次要结局
- Postoperative tumor-free survival period(3 years after the second liver resection)
