PET/CT in Diagnosing Patients With Liver Cancer Undergoing Surgical Resection
Genomic and Imaging Study for Patients Undergoing Surgery for Liver Cancer
Studie Overzicht
Toestand
Gedetailleerde beschrijving
PRIMARY OBJECTIVES:
I. Determine the most optimal fluorine-18 (18F) fluoromethylcholine (FCH) PET/CT parameters for detecting primary hepatocellular carcinoma (HCC) by conducting a clinical radiologic-pathologic correlation study to estimate and compare the receiver operating characteristics of kinetic and static PET measures of tumor FCH metabolism in patients that test positive during screening or conventional imaging.
II. Identify cancer signaling pathways associated with choline metabolism in HCC by profiling the global gene expression patterns in fresh-frozen liver tissue samples that are correlated with the features derived from FCH PET/CT images.
III. Characterize the association between features derived from FCH PET/CT images of the liver and clinical liver disease severity and comparatively evaluate the ability of corresponding gene expression signatures to predictively model HCC disease outcome.
OUTLINE:
Patients undergo 18F-fluoromethylcholine PET/CT within 14 days of surgical resection.
After completion of study treatment, patients are followed up periodically.

Fluorine-18 (18F) Fluoromethylcholine (FCH) PET/CT Parameters for Assessing Hepatocellular Carcinoma (HCC): Area Under the Receiver Operating Characteristic Curve.
Tijdsspanne: Up to study completion at an average of 2.5 years
|
Area under the receiver operating characteristic curve for detecting resectable hepatocellular carcinoma with prognostically favorable molecular features (Hoshida molecular sub-class S3) based on FCH PET/CT measurement of tumor maximum standardized uptake value (SUVmax).

Fluorine-18 (18F) Fluoromethylcholine (FCH) PET/CT Parameters for Assessing Hepatocellular Carcinoma (HCC): Sensitivity/Specificity
Tijdsspanne: Up to study completion at an average of 2.5 years
|
Sensitivity and specificity estimated at a predefined point (ie.
Youden's maxima) on the receiver operating characteristic curve for detecting hepatocellular carcinoma with prognostically favorable molecular features (Hoshida molecular sub-class S3) based on FCH PET/CT measurement of tumor maximum standardized uptake value (SUVmax) in patients who underwent subsequent tumor resection.

Statistical Significance of Molecular Pathways Associated With Choline Metabolism as Identified Through Gene Set Enrichment Analysis of Hepatocellular Carcinoma (HCC) Tumor Samples.
Tijdsspanne: Up to study completion at an average of 2.5 years
|
Statistically significant enrichment by sets of genes corresponding to previously-defined molecular pathway signatures was assessed by gene set enrichment analysis (a publicly available algorithm) of whole-genome expression array data obtained from tumors previously characterized by FCH PET/CT.
Statistical significance was based on a false discovery rate < 0.05.
Tumors demonstrating high choline metabolism (defined by a tumor-liver ratio > 1.0 measured on PET) were assessed for enrichment by publicly-available gene sets.
This particular analysis involved the entire Molecular Hallmarks gene signature collection (v6.0) as obtained from the Broad Institute Molecular Signature Database (MSigDB).

Odds ratios and 95% confidence intervals for histologic liver fibrosis (Metavir) stage >= F1, >= F2, >= F3, and F4 at liver standardized uptake value (SUV) thresholds of 8.3, 8.0, 7.4, and 6.4, respectively.

Number of Participants Comprising Two Distinct PET/CT Imaging Phenotypes (High FCH Uptake vs. Low FCH Uptake) Between the Different Tumor Sub-classes
Tijdsspanne: Up to study completion at an average of 2.5 years
|
HCC tumors were sub-classified using gene expression arrays into 3 distinct prognostically-relevant molecular sub-classes (S1,S2, S3, where S3 is associated with the most favorable clinical prognosis) based on Hoshida et.
al (PMID 19723656).
The number of tumors comprising two distinct PET/CT imaging phenotypes (high FCH uptake vs. low FCH uptake) was compared between the different sub-classes.
