About this study

Official title: Evaluation of a Novel Blood Test Hypercoagulability in Surgical Patients With Metastatic Carcinoma: A Pilot Study

RATIONALE: A test that detects abnormal blood clotting in patients with cancer may help doctors plan cancer surgery.

PURPOSE: This laboratory study is looking at a new blood test to detect abnormal clotting in patients with metastatic cancer undergoing surgery.

Read the detailed description

OBJECTIVES:

Primary

  • Determine whether whole blood thrombin generation assay (WBTGA) detects hypercoagulability in patients with metastatic carcinoma compared with a healthy control group.
  • Determine whether results of the WBTGA will change as a result of major surgery performed on patients with metastatic carcinoma.
  • Establish a reference interval for the WBTGA using healthy controls.

Secondary

  • Compare a battery of plasma components known to affect or reflect coagulant or fibrinolytic reactions in patients with metastatic carcinoma vs healthy controls.
  • Establish reference intervals for this battery of tests using healthy controls.
  • Determine how major surgery in cancer patients affects this battery of factors.
  • Identify changes in these factors that correlate with changes in the WBTGA.
  • Compare the results of WBTGA tests in patients who develop venous thromboembolism (VTE) with those who do not.

OUTLINE: This is a pilot study.

Blood samples of patients are collected on day -7 and day 1 after surgery.

Blood samples of healthy controls are collected once.

After collection, blood samples are analyzed for hypercoagulability by whole blood thrombin generation assay. Routine blood tests are performed, as are immunoenzyme techniques for antigenic tissue plasminogen activator and its inhibitor, thrombin-antithrombin complexes, tissue factor, factor VIIa, D-dimer, and glycocalicin.

PROJECTED ACCRUAL: A total of 30 patients and 30 healthy controls will be accrued for this study.

Being tested
coagulation study, immunoenzyme technique, laboratory biomarker analysis, physiologic testing, study of high risk factors
Keywords
thromboembolism, unspecified adult solid tumor, protocol specific

Questions about this trial

What is this clinical trial studying?

An observational study of Thromboembolism and Unspecified Adult Solid Tumor, Protocol Specific, run by National Cancer Institute (NCI) 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 12 May 2009. 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?

Incidence of hypercoagulability. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00096590, which also lists 1 linked publication.

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 12 May 2009.
