About this study

Official title: Assessment of Patterns of Expression of VEGF, Matrix Metalloproteinase 2, 9 Activity, E-Cadherin Regulation and CA-9 Activity as Predictors of Aggressive Renal Cell Carcinoma Behavior

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.

PURPOSE: This research study is looking at tumor tissue samples from patients who have undergone surgery for localized kidney cancer.

Read the detailed description

OBJECTIVES:

  • To identify consistent patterns of VEGF expression, E-cadherin regulation, matrix metalloproteinase 2 and 9 activity, and carbonic anhydrase 9 activity as predictive factors in the development of aggressive tumor behavior in tumor tissue samples from patients with localized clear cell renal cell carcinoma.

OUTLINE: Previously collected tumor tissue samples are examined by immunohistochemistry for levels of expression of five different factors related to aggressive tumor behavior (i.e., VEGF expression, E-cadherin regulation, matrix metalloproteinase 2 and 9 activity, and carbonic anhydrase 9 activity). Samples are compared to positive tissue controls (i.e., VEGF- tonsil; E- cadherin-normal breast or endometrium; MMP2- placenta) and a negative control (i.e., isotype matched normal serum) to identify consistent patterns of expression/activity of these factors. Levels of expression are quantified as 5-level scores (0 to 4 scale) and differences between any two areas of a tumor are analyzed.

Questions about this trial

What is this clinical trial studying?

An observational study of Kidney Cancer, run by Case Comprehensive Cancer Center.

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

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 30 Sep 2015.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The study was withdrawn before enrolling participants, so there are no results.

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?

Relative patterns of expression/activity of five different growth factors/enzymes inherently related to the development of metastatic renal cell carcinoma behavior. 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.
