Detection of Plasma DNA Methylation in Peripheral Blood From Patients With Resectable Liver Cancer

Recruiting

Interventions: Procedure: Biospecimen Collection
Other: Electronic Health Record Review

Brief Summary: This study explores the potential values of a new blood test approach to detect measurable residual disease or early coming back of cancer (recurrence)/cancer growing, spreading, or getting worse (progression) in patients with liver cancer that can be removed by surgery (resectable). The development of novel cancer biomarkers for liver cancer may help in clinical decision making and lead to improvements in patient outcomes by facilitating prediction of the response to specific treatments, improved monitoring of patients on treatment, and better prognostication of patient outcomes, thus improving stratification for clinical trials.

Detailed Description: PRIMARY OBJECTIVES:

I. To isolate plasma deoxyribonucleic acid (DNA) methylation panel from the peripheral blood of treated patients with hepatocellular carcinoma that will correlate with disease progression or measurable residual disease.

II. To correlate the mutations/ DNA methylation in peripheral blood with those identified in parallel tumor samples from the same patients with hepatocellular (HCC).

OUTLINE:

Patients undergo collection of blood samples at 4-6 weeks prior to surgery/ablation and at 12 weeks, 6, 12, 18 and 24 months after surgery/ablation. Patients' previously collected tissue samples are analyzed. Patients' medical records are also reviewed at baseline, 4-6 weeks prior to surgery/ablation, 12 weeks, 6, 12, 18 and 24 months after surgery/ablation, and then every 6 months for 3 years.

Recruitment & Eligibility

Inclusion Criteria

Patient has planned resection or ablation of suspected hepatocellular carcinoma
Patient is classified as resectable T1/T2 hepatocellular carcinoma (HCC) (solitary tumors less than or equal to 2 cm OR solitary tumors without vascular invasion > 2cm or solitary tumor with vascular invasion > 2cm, or multiple tumors, none > 5cm) OR BCLC stage A (Single lesion of ANY size or 3 nodules or less with each being 3cm or less)

Exclusion Criteria

Patient is younger than 18 years of age
Females who are pregnant or attempt to become pregnant
Patient with significant anemia (hemoglobin [Hb] < 7g/dL)

Patient has had a biopsy to the target organ and/or lesion within 3 days before blood collection
Patient has had an intervention to completely remove current target pathology
Target pathology is a recurrence of previously treated HCC
Patient has had prior resection or ablation for target lesion
Patient has had prior or active chemotherapy or radiation for target lesion

Primary Outcome Measures

Name	Time	Method
Multi-target hepatocellular carcinoma panel (MHP) score	Up to 1 year	Descriptive statistics will be used. The association between the MHP score and patient and tumor characteristics with state occupancy probability will be examined using the Cox proportional hazards model. Serial measurements of the MHP score obtained on subsequent visits will be accounted for within the Cox model by treating them as time varying covariate. To assess the relative importance of the MHP score to individual alpha fetoprotein (AFP) levels for the prediction of hepatocellular carcinoma recurrence, the area under the receiver operator characteristic curve will be compared between the MHP score model and an AFP only model.
