About this study
Official title: Investigation of Thioredoxin-1 Family Protein Expression in Rectal Cancer
RATIONALE: Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment.
PURPOSE: This research study is looking at protein expression in tumor tissue samples from patients with stage II or stage III rectal cancer enrolled in clinical trial SWOG-9304.
Read the detailed description
OBJECTIVES:
- Determine expression levels of thioredoxin-1 (Trx-1), thioredoxin-interacting protein (TXNIP), and hypoxia inducible factor-1 alpha (HIF-1α) in paraffin-embedded resected tumor tissue samples from patients with stage II or III rectal cancer enrolled in clinical trial SWOG-9304.
- Determine if there is a correlation between Trx-1 and TXNIP expression and HIF-1α expression.
- Correlate expression of these proteins with tumor stage, disease-free survival, overall survival, and risk of recurrence.
- Determine interactions for patient age, performance status, and type of therapy received on clinical trial SWOG-9304.
OUTLINE: This is a multicenter study.
Paraffin-embedded resected tumor tissue samples are analyzed for protein expression levels (thioredoxin-1, thioredoxin-interacting protein, and hypoxia inducible factor-1 alpha) by tissue microarray and immunostaining.

Questions about this trial
What is this clinical trial studying?
An observational study of Colorectal Cancer, run by SWOG Cancer Research Network.
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 30 Sep 2015. Status can change between updates, so confirm with the study contact before making plans.
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?
Expression of thioredoxin-1, thioredoxin-interacting protein, and hypoxia inducible factor-1 alpha (time frame: upon testing of specimens). The study lists 2 primary outcomes in all. 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 30 Sep 2015.
