About this study

Official title: Pilot Study of Ex-Vivo Molecular Polyp Imaging Using 18-F Fluorodeoxyglucose (FGD) Positron Emission Tomography (PET) in the Determination of Protein and Gene Expression Signatures of Premalignant Polyps

RATIONALE: Diagnostic imaging procedures, such as fludeoxyglucose F 18 PET, may be effective in detecting cancer or recurrence of cancer, or premalignant polyps.

PURPOSE: This clinical trial is studying fludeoxyglucose F 18-PET imaging to see how well it works in determining protein and gene expression signatures in patients with premalignant polyps or colon cancer.

Read the detailed description

OBJECTIVES:

Primary

  • To determine the feasibility of ex-vivo imaging of colon cancer and colon polyps using fludeoxyglucose F 18 positron emission tomography (FDG PET).
  • To evaluate the differences in molecular and genetic profiles between FDG-positive polyps and FDG-negative polyps to suggest what gene mutations and abnormal mRNA and/or protein expressions may be required for FDG avidity ("signature" for FDG avidity).

Secondary

  • To evaluate the differences in molecular and genetic profiles between FDG-positive polyps and FDG-positive cancers to suggest what gene mutations and abnormal mRNA and/or protein expressions may be required for cancer formation ("signature" for cancer).
  • To evaluate the differences in molecular and genetic profiles between normal colonic mucosa, polyps, and cancer.
  • To evaluate the differences and similarities in molecular and genetic profiles between FDG-positive cancers and polyps.

OUTLINE: Part I: Patients receive fludeoxyglucose F 18 (FDG) IV followed 45-60 minutes later by surgery to remove part or all of the colon. Tissue samples of the colon undergo positron emission tomography (PET) imaging.

Part II: Tissue samples are analyzed for glucose transporters proteins (Glut-1, 2, 3, 4, 5, 7) via IHC; presence of K-ras mutation (invariable mutant site on codon 12, 13) via PCR; 18q deletion via fluorescence in situ hybridization (FISH) or DCC IHC; MCT-1, Hex-1, Hex-2, and COX-2 expression levels via quantitative RT-PCR method or western blot; APC mutation via PCR- In Vitro Synthesized-Protein Assay or RT-PCR direct sequencing method; p53 mutation detection via immunochemistry, RT-PCR direct sequence methods, and western blot; methylation alteration of MGMT, CDKN2A, HLTF, MLH1, TIMP3, HIF1, BNIP3, and HRK via methylation detecting microchip; and specific gene methylations via methylation-specific PCR. Some tissue samples may be saved and banked for future studies.

Being tested
DNA methylation analysis, fluorescence in situ hybridization, gene expression analysis, polymerase chain reaction, protein expression analysis
Keywords
neoplasm of uncertain malignant potential, colon cancer

Questions about this trial

What is this clinical trial studying?

An observational study of Colorectal Cancer and Neoplasm of Uncertain Malignant Potential, run by Memorial Sloan Kettering Cancer Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 23 Dec 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Feasibility of ex-vivo imaging of colon cancer and colon polyps using fludeoxyglucose F 18 positron emission tomography (FDG PET) (time frame: 2 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Dec 2015.
