Trial summary

Because the management of children with solid tumors hinges on the extent of disease, it is crucial to identify metastatic sites. Helical chest computed tomography (CT) is the standard method of excluding pulmonary metastases. Read more about this study

About this study

Because the management of children with solid tumors hinges on the extent of disease, it is crucial to identify metastatic sites. Helical chest computed tomography (CT) is the standard method of excluding pulmonary metastases. However, CT lacks molecular information regarding nodule histology and often biopsy is required to exclude malignancy. Biopsy procedures carry known risks including those associated with anesthesia and sedation, infection, pneumothorax, hemorrhage, pain and other post-procedure and post-operative complications and may also add unnecessary cost to the management of the patient. We found that the ability of three experienced pediatric radiologists to correctly predict nodule histology based on CT imaging features was limited (57% to 67% rate of correct classification). Also, there was only slight to moderate agreement in nodule classification between these reviewers.

Furthermore, of 50 children who have undergone pulmonary nodule biopsy at St. Jude in the last five years, 44% (22/50) had only benign nodules.

Adult studies have shown that a nuclear medicine scan called fluoro-deoxyglucose (FDG) positron emission tomography (PET) and the fusion modality PET-CT are superior to diagnostic CT in distinguishing benign from malignant pulmonary nodules because FDG PET gives information about the metabolic activity of the nodule. Nodules that are malignant have more metabolic activity, hence more FDG uptake/intensity, than those that are benign. There has been little work done in children to determine the value of PET or PET-CT in the evaluation of pulmonary nodules.

Read the detailed description

In this study, we seek to assess the feasibility of performing PET-CT for the evaluation of pulmonary nodules in children to obtain preliminary data for sample size determination for a larger multi-institutional trial. The primary objective of the multi-institutional trial will be to compare the accuracy of diagnostic CT alone to PET-CT in distinguishing benign from malignant nodules in children with solid malignancies. We are hopeful that PET-CT will allow us to better direct the clinical management of these patients and to reduce the number of invasive procedures performed to confirm the presence of benign disease.

Questions about this trial

What is this clinical trial studying?

An observational study of Pulmonary Nodules, run by St. Jude Children's Research Hospital 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 2 inclusion and 1 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 17 Oct 2012. 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?

To assess the feasibility of performing PET-CT for the evaluation of pulmonary nodules in children with solid malignancies and to obtain preliminary data for sample size determination for a larger, multi-institutional prospective study. (time frame: 2 years). 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 17 Oct 2012; AzTrials last refreshed its copy on 7 Nov 2026.
