About this study

Official title: Observational - Tissue Factor Expression in Bone Sarcomas

This trial studies biomarker expression in tissue samples from patients with bone sarcomas. Studying biomarker in tissue samples from patients with cancer in the laboratory may help doctors identify and learn more about biomarkers related to cancer

Read the detailed description

STUDY SUBTYPE: Ancillary/Correlative

OBSERVATIONAL STUDY MODEL: Case-only

TIME PERSPECTIVE: Retrospective

BIOSPECIMEN RETENTION: Samples without DNA

BIOSPECIMEN DESCRIPTION: Tissue samples obtained from Cooperative Human Tissue Network (CHTN)

STUDY POPULATION DESCRIPTION: Patients enrolled on P9754 and AOST0121 clinical trials

SAMPLING METHOD: Non-probability sample

PRIMARY OBJECTIVES:

  1. To determine if there is differential expression of tumor factor (TF) among patients with osteosarcoma.

II. To determine if there is an association between overall survival and disease free survival and the extent of TF expression.

III. To determine if TF expression correlates with presence of gross metastatic disease at presentation, and development of subsequent metastases.

OUTLINE:

Tissue samples are analyzed for tumor factor expression levels by immunohistochemistry.

What is being measured

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

  1. Prevalence of high TF expression

    Estimated in the analytic population as the number of samples in the population in which such expression is noted divided by 33. An assessment of the precision of such estimates will be provided by an exact binomial confidence interval. Comparison of normalized TF expression in non-metastatic versus metastatic patients will be done using the two-sample t-test.

    Measured: 1 month

Questions about this trial

What is this clinical trial studying?

An observational study of Localized Osteosarcoma and Metastatic Osteosarcoma, run by Children's Oncology Group 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?

The sponsor lists 3 inclusion and 0 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 19 May 2016. 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?

Prevalence of high TF expression (time frame: 1 month). 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 19 May 2016; AzTrials last refreshed its copy on 29 Oct 2026.
