About this study

Official title: Comparative Study of Gross Tumor Volume Definition With or Without PET Fusion for Patients With Non-Small Cell Lung Carcinoma

RATIONALE: Imaging procedures, such as positron emission tomography (PET) scan and CT scan, may help doctors plan radiation therapy for patients with non-small cell lung cancer.

PURPOSE: This clinical trial is studying how well a combined PET scan and CT scan works compared to a CT scan alone in planning radiation therapy for patients with stage II or stage III non-small cell lung cancer.

Read the detailed description

OBJECTIVES:

Primary

  • Determine the impact of positron emission tomography (PET)/CT fusion scan and CT scan alone, by comparing gross tumor volume (GTV) contours and three-dimensional conformal radiotherapy treatment plans using 2 separate data sets (PET/CT fusion scan and CT scan only), in patients with stage II or III non-small cell lung cancer who are planning to undergo radiotherapy.
  • Determine the impact of PET on GTV (cm^3), number of involved nodes, location of involved nodes, and dosimetric measures of normal tissue toxicity (mean lung dose, V20, and mean esophageal dose).

Secondary

  • Determine the rate of elective nodal failures (nodal failures in regions that are not intentionally irradiated to definitive doses [i.e., ipsilateral hilum, mediastinum, or ipsilateral supraclavicular fossa]).

OUTLINE: This is a multicenter study. Patients are stratified according to neoadjuvant chemotherapy (yes vs no).

Patients undergo a combined positron emission tomography (PET)/CT scan. Patients also undergo a CT scan alone. A single three-dimensional conformal radiotherapy (3DCRT) plan is generated from the combined PET/CT scan results. A single 3DCRT plan using the planning target volume is derived from the CT scan only.

Patients are followed every 3 months for 1 year, every 6 months for 2 years, and then annually thereafter.

PROJECTED ACCRUAL: A total of 48 patients will be accrued for this study.

What is being measured

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

  1. The impact of positron emission tomography (PET)/CT fusion planning on GTV (cm³) vs. planning with CT scan alone

    Measured: Two treatment plans are centrally reviewed to determine the difference in gross tumor volume between the plans

  2. The impact of positron emission tomography (PET)/CT fusion planning on number of contoured lymph nodes vs. planning with CT scan alone

    Measured: Two treatment plans are centrally reviewed to determine the difference in number of contoured lymph nodes between the plans

  3. The impact of positron emission tomography (PET)/CT fusion planning on location of involved lymph nodes vs planning with CT scan alone

    Measured: Two treatment plans are centrally reviewed to determine the difference in location of involved lymph nodes between the plans

  4. The impact of positron emission tomography (PET)/CT fusion planning on lung V20 vs planning with CT scan alone

    Measured: Two treatment plans are centrally reviewed to determine the difference in lung V20 between the plans

  5. The impact of positron emission tomography (PET)/CT fusion planning vs planning with CT scan alone on mean esophagus dose

    Measured: Two treatment plans are centrally reviewed to determine the difference in mean esophagus dose between the plans

Secondary outcomes (1)
  1. Rate of elective nodal failures as assessed by failure in previously uninvolved regional lymph nodes at 2 years

    Measured: From registration to 2 years

Questions about this trial

What is this clinical trial studying?

A study testing computed tomography and positron emission tomography in people with Lung Cancer, run by Radiation Therapy Oncology Group at 4 sites in 2 countries.

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 24 Jan 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in United States, Canada. 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?

The impact of positron emission tomography (PET)/CT fusion planning on GTV (cm³) vs. planning with CT scan alone (time frame: Two treatment plans are centrally reviewed to determine the difference in gross tumor volume between the plans). The study lists 5 primary outcomes in all. 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 NCT00310219, 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 24 Jan 2014.
