RATIONALE: Studying samples of blood, urine, and tissue in the laboratory from patients with cancer or chronic liver disease may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer.
PURPOSE: This clinical trial is studying blood, mouthwash, urine, and tissue samples from healthy volunteers and patients with liver cancer or chronic liver disease.
- Identify biomarkers related to hepatocellular carcinoma (HCC) that can be used for early diagnosis and prevention using tissue, blood, and/or urine samples from patients with HCC, patients at high risk for HCC, and healthy population-based volunteers (controls).
- Perform proteomic and metabolomic analysis of blood or urine samples from patients with HCC, patients at high risk for HCC, and healthy controls.
- Collect data from questionnaires, medical and pathology records, and the National Death Index.
- Assess biomarkers related to HCC diagnosis, prognosis, metastasis, and molecular subtypes using tissue samples (tumor and nontumor by needle biopsy) from patients with HCC.
- Perform candidate and genome-wide association studies to identify and validate genomic risk factors that are associated with HCC.
- Examine the relationship between genetic variants and morphologic, molecular, clinical, and prognostic outcome endpoints using genotype analysis of blood or mouthwash DNA and collection of data from questionnaires, medical and pathology records, and the National Death Index.
OUTLINE: Patients and healthy volunteers undergo an interview using a general questionnaire and a supplemental liver questionnaire. Healthy male volunteers also complete a supplemental prostate questionnaire. After the interview, blood and urine samples are collected. Fresh-frozen or paraffin-embedded tumor and nontumor tissue samples are also obtained from patients with hepatocellular carcinoma. Patients and healthy volunteers may be re-contacted in order to obtain additional questionnaire information and/or blood/urine samples.
Blood or mouthwash samples are used for the analysis of genotypes, single nucleotide polymorphisms, methylation status, and the measurement of cytokine and microRNA concentrations. Urine samples are used for metabolomic studies. Tissue samples are used for whole-genome gene expression analysis and the preparation of tissue arrays for immunohistochemical analysis of protein expression.
Outcome data (survival) is obtained from medical records, Veteran Administration databases, State of Maryland records, Social Security Death Index, and the National Death Index.
PROJECTED ACCRUAL: A total of 250 patients with primary hepatocellular carcinoma (HCC), 500 patients with chronic liver disease (high risk for HCC), and 500 healthy population-based volunteers (controls) will be accrued for this study.

MOLECULAR BIOLOGY techniques used in the diagnosis of disease. Included are such techniques as IN SITU HYBRIDIZATION of chromosomes for CYTOGENETIC ANALYSIS; OLIGONUCLEOTIDE ARRAY SEQUENCE ANALYSIS of gene expression patterns in disease states; identification of pathogenic organisms by analysis of species specific DNA sequences; and detection of mutations with POLYMERASE CHAIN REACTION.
A method of chemical analysis based on the detection of characteristic radionuclides following a nuclear bombardment. It is also known as radioactivity analysis. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)
Meta-analysis of randomized trials in which estimates of comparative treatment effects are visualized and interpreted from a network of interventions that may or may not have been evaluated directly against each other. Common considerations in network meta-analysis include conceptual and statistical heterogeneity and incoherence.
