Prediction of Hepatocellular Carcinoma Recurrence After Curative Treatment by Longitudinal Monitoring MRD Based on ctDNA

Study Overview
=================
Brief Summary
-----------------
This study will conduct a prospective cohort study to verify the predictive value of ctDNA-MRD longitudinal monitoring model in predicting postoperative recurrence, verify whether ctDNA-MRD longitudinal monitoring model can indicate recurrence earlier than imaging examination, and explore the feasibility of guiding adjuvant therapy after curative treatment based on this model.

Detailed Description
-----------------
The recurrence rate of hepatocellular carcinoma after curative treatment is high, and the minimal residual disease(MRD) in patients is the major cause of liver cancer recurrence, and the MRD is an important basis for the decision of adjuvant therapy after curative treatment. Previous studies have confirmed that circulating tumor DNA(ctDNA)-MRD monitoring model can accurately predict the recurrence of hepatocellular carcinoma patients. It was also found in retrospective analysis that tumor free survival was significantly prolonged after ctDNA-positive treatment for hepatocellular carcinoma after resection. This study will conduct a prospective cohort study to verify the predictive value of ctDNA-MRD longitudinal monitoring model in predicting postoperative recurrence, verify whether ctDNA-MRD longitudinal monitoring model can indicate recurrence earlier than imaging examination, and explore the feasibility of guiding adjuvant therapy after curative treatment based on this model.This study is to verify the predictive value of ctDNA-MRD longitudinal monitoring model in predicting postoperative recurrence.
