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.
aged 18-75 years;
patients with unresectable primary hepatocellular carcinoma or colorectal cancer with liver metastases who also meet the following criteria: tumor shrinkage (still unresectable) or no significant progression after a first-line chemotherapy regimen of 6-8 weeks; no other abdominal metastases or 1-3 resectable pulmonary metastases;
patients with end-stage liver disease;
preoperative Child classification of A or B, able to tolerate the subsequent surgical program
Extrahepatic tumor burden (except for resectable lung metastases) and/or macrovascular tumor infiltration
Tumor progression during chemotherapy or important comorbidities that affect surgery
Uncorrectable cardiopulmonary disease with high surgical risk
Anatomical abnormalities that preclude liver transplantation
Single group
assisted liver transplantation combined with two-stage hepatectomy
Procedure/SurgeryStage 1 Surgery: Left Hepatectomy, Left Lateral Graft Implantation, Portal Shunt to Graft Intermediate stage: continuous monitoring of liver function indexes and liver transplant donor volume after the first stage of surgery. Until the graft size reaches 0.8% of body weight (GBWR), or 35%-45% of the standard liver volume. Stage 2 Surgery: Residual Right Hepatectomy
Three-year overall survival rate after surgery
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.
Postoperative tumor-free survival period
After the second liver resection, regular follow-up of patients' serological and imaging indicators: Serological indicators include tumor markers, such as AFP, AFP heterogeneity, CEA, CA19-9, etc., imaging Medical indicators include abdominal ultrasound, enhanced CT, enhanced magnetic resonance or PET-CT examination. Serological examination and B-ultrasound examination should be performed once a month for the first year after surgery, and once every three months for the next two years. Enhanced CT or enhanced MRI should be performed at the 1st, 3rd, and 6th months after operation, and then once every six months (if the serology or B-ultrasound examination indicates abnormalities, an additional examination will be performed). Two or more imaging examinations diagnosed as malignant tumors were considered as tumor recurrence. Tumor recurrence or no recurrence after three years of follow-up was used as the end point of the study.
