Study of DNA in Blood Samples From Patients With Neuroblastoma

May 16, 2016 updated by: Children's Oncology Group

Analysis of Circulating MYCN DNA in Serum Samples Obtained From Patients With Neuroblastoma

This research trial studies is deoxyribonucleic acid (DNA) in blood samples from patients with neuroblastoma. Studying samples of blood 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.

Study Overview

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

OBJECTIVES:

I. Perform in a blind study a multicentric study by analyzing serum from patients at diagnosis (with a known tumor v-myc avian myelocytomatosis viral oncogene neuroblastoma derived homolog (MYCN) status determined in the Children's Oncology Group [COG] reference lab), in order to confirm our previous data and to define the most appropriate MYCN/control ratio cutoff capable of determining positive and negative cases.

II. Define the limits of the procedure in non-metastatic patients and in those with reduced tumor burden (International Neuroblastoma Staging System [INSS] stage 1 and 2).

OUTLINE:

Circulating DNA is extracted from serum. Polymerase chain reaction (PCR) amplification of MYCN is performed and analyzed by agarose gel electrophoresis. Real-time quantitative PCR is also performed.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Probability Sample

Study Population

Patients with neuroblastoma treated at a COG participating site.

Description

Inclusion Criteria:

  • Serum samples from neuroblastoma (NB) patients obtained through the COG (and legacy Children's Cancer Group [CCG]/Pediatric Oncology Group [POG] Biology Studies)

    • The MYCN status on corresponding tumors have been determined using standard techniques; the panel of samples must be obtained from NB patients with and without MYCN amplification tumors
  • Cases will be drawn from clinical subsets at greatest likelihood to benefit from this testing ability, stage 1 and 2 NBs (both infants and toddlers), stage 4 patients under 18 months of age, and 4S patients

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame

Time Frame: Up to 6 months
Up to 6 months
Limits of the procedure in non-metastatic patients and in those with reduced tumor burden
Time Frame: Up to 6 months
Up to 6 months

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
June 1, 2007

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
