Clinical Research on Dynamic Monitoring MRD Via Plasma ctDNA After Systemic Therapy of Hepatocellular Carcinoma

Study Overview
=================
Brief Summary
-----------------
This study aims to combine biomarker characteristic atlas and ctDNA detection technology to establish a precise standard scheme for minimal residual diagnosis of liver cancer after surgery and systemic treatment.

Detailed Description
-----------------
This study is a prospective, single-blind, randomized, controlled, single-center study. The patients with liver cancer are recruited after surgery or systemic treatment. Intraoperative cancer and para-cancer tissues of surgical patients are collected, and peripheral blood of all patients after multiple follow-up visits before and after treatment are also collected. The established detection method and model are used to detect blood ctDNA of patients with liver cancer after treatment, and the follow-up data are collected to observe the correlation between the genomic characteristics of plasma at multiple follow-up points after treatment and the recurrence or progression after treatment. The sensitivity and specificity of ctDNA detection method is calculated to predict the risk of relapse or progression after treatment.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Sensitivity of plasma ctDNA mutation and methylation model to predict disease-free survival (DFS) or progression-free survival (PFS) in patients with primary hepatocellular carcinoma after treatment | Plasma ctDNA mutation and methylation are detected after treatment in patients with primary hepatocellular carcinoma who underwent hepatectomy or systemic therapy. Clinical information of disease-free survival (DFS) or progression-free survival (PFS) is collected to explore the predictive effect of plasma ctDNA mutation and methylation status on the prognosis of primary hepatocellular carcinoma after treatment. | 2 years | 
| The advance time of ctDNA dynamic detection compared with AFP+ imaging in monitoring of primary hepatocellular carcinoma recurrence or progression | Patients with primary hepatocellular carcinoma who underwent hepatectomy or systemic therapy are followed up regularly after treatment. During follow-up, plasma ctDNA test results, traditional tumor marker AFP and imaging evaluation data are collected. Mutations and methylation of plasma ctDNA are detected. All the data is analyzed to explore the advance time of dynamic detection of plasma ctDNA mutation and methylation in monitoring recurrence or progression of primary hepatocellular carcinoma compared with AFP+ imaging monitoring. | 6 months |
