About this study

Official title: A Study to Determine the Immunopheotype of Locally Advanced Rectal Adenocarcinoma and Its Correlation With the Efficacy of Neoadjuvant Chemoradiotherapy

This is an observational study of tumor samples and MRI imaging in patients with colorectal cancers. A tumor sample, MRI scans, and treatment outcome data will be used for research purposes to see if it is possible to predict patients' response to treatment.

Read the detailed description

The quality of the immune environment in colorectal cancer biopsy samples correlates with disease-free survival and overall survival more so than current staging conventions. This study will use a scoring system called 'immunoscore' to characterize the immune enviroment. Researchers hypothesize that the immunoscore will correlate with outcomes of colorectal patients treated with neoadjuvant chemoradiation.

Being tested
Diagnostic Biopsy and Surgical Procedure, Intravoxel incoherent motion MRI (IVIM), Dynamic Contrast Enhanced MRI (DCE-MRI), RNA gene expression analysis
Keywords
Immunophenotype, Immunoscore, MRI, RNA Later

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Diagnostic Biopsy and Surgical ProcedureProcedure or surgery

    A tumor sample from the diagnostic biopsy and surgical procedure will be used for research.

  • Intravoxel incoherent motion MRI (IVIM)Procedure or surgery

    At the end of a standard MRI, we will perform IVIM, which is a diffusion-weighted imaging sequence that simultaneously characterizes the microscopic diffusivity of water and the macroscopic transport of water via bulk flow. IVIM may more accurately reflect the properties of the tumor microenvironment including vascular permeability, interstitial fluid pressure, and response to neoadjuvant therapy.

  • Dynamic Contrast Enhanced MRI (DCE-MRI)Procedure or surgery

    Following a standard MRI scan, Dynamic Contrast Enhanced MRI (DCE-MRI) will be done. DCE-MRI is an indicator-dilution experiment in which the delivery and transcapillary transfer of a contrast agent, typically one of a number of gadolinium-based contrast agents (GBCA), is used to assess a number of parameters characterizing tissue physiology. In locally advanced rectal cancer patients, use of DCE-MRI for determining pathologic response has produced equivocal results but more promising data has been published recently in the cervical cancer literature.

  • RNA gene expression analysisGenetic

    RNA will be collected from biopsy and surgical tissue for gene expression analysis.

Study groups in NCT02017509
Study groupRoleWhat they receive
Rectal Cancer PatientsPatients with a diagnosis adenocarcinoma of the rectum will provide a tumor sample from their diagnostic biopsy and surgical procedure for research purposes, including RNA gene expression analysis. In addition to a standard MRI, patients will have an Intravoxel Incoherent Motion MRI (IVIM) and a Dynamic Contrast Enhanced MRI (DCE-MRI) for research purposes.
Receives: Procedure: Diagnostic Biopsy and Surgical Procedure; Procedure: Intravoxel incoherent motion MRI (IVIM); Procedure: Dynamic Contrast Enhanced MRI (DCE-MRI); Genetic: RNA gene expression analysis

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Correlation of the number of infiltrating leukocytes within a biopsy sample with pathologic response

    Quantitative immunohistochemical analysis will be performed on parameters of interest on both pre-treatment biopsy specimens as well as post-operative specimens. The pre-treatment sample will be used to establish the immunophenotype score. The primary analysis will evaluate the ability of immunophenotype score to correlate with pathologic response.

    Measured: 16 weeks

Individual data sharing
Yes: This project is being done to contribute pathology samples and patient outcome data to a larger data set intended to validate an algorithm to predict patient outcome based on pathology data obtained at diagnosis. As part of this project, pre-existing samples will be used. There will be new slides made from the samples that will be stained to identify immune response. Pathology analysis and images of the slides will be provided (without patient identifiers) along with de-identified patient outcome data to a central coordinating center.

Questions about this trial

What is this clinical trial studying?

An observational study of Cancer of the Rectum and Neoplasms, Rectal, run by Providence Health & Services at 2 sites 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?

The sponsor lists 3 inclusion and 2 exclusion criteria. 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 29 Aug 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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?

Correlation of the number of infiltrating leukocytes within a biopsy sample with pathologic response (time frame: 16 weeks). 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 29 Aug 2018.
