Lung Cancer Clinical Trial

Dynamic Perfusion Computed Tomography in Patients With Localized Non-small Cell Lung Cancer

Summary

This pilot clinical trial studies the changes in dynamic perfusion computed tomography images before, during, and after stereotactic body radiation therapy in patients with stage I-II non-small cell lung cancer that has not spread to other parts of the body. Diagnostic imaging procedures, such as dynamic perfusion computed tomography, measure blood flow through tumors. Stereotactic body radiation therapy is a specialized radiation therapy that sends x-rays directly to the tumor using smaller doses over several days and may cause less damage to normal tissue. Giving dynamic perfusion computed tomography images before, during, and after stereotactic body radiation therapy may help better understand how radiation therapy works to stop tumor growth in patients with non-small cell lung cancer.

Full Description

PRIMARY OBJECTIVES:

I. To describe perfusion computed tomography (CT) parameters and their changes in non-small cell lung cancer (NSCLC) tumors prior to, during, 1 month after, and 3 months after stereotactic body radiation therapy (SBRT).

SECONDARY OBJECTIVES:

I. To correlate tumor perfusion parameters with clinical tumor response on follow up per standard of care.

TERTIARY OBJECTIVES:

I. To correlate changes in serum levels of deoxyribonucleic acid (DNA) methylation and circulating tumor cell (CTC) with clinical response rates and perfusion parameters.

OUTLINE:

Patients undergo dynamic perfusion computed tomography (DPCT) at baseline, during SBRT (after 2 of 3 fractions or 3 of 5 fractions), and then at 1 and 3 months post stereotactic body radiation therapy.

After completion of study, patients are followed up at 6, 12, 18, and 24 months.

Eligibility Criteria

Inclusion Criteria:

Biopsy proven non-small cell lung cancer
Minimum tumor dimension >= 1 cm (preferably >= 2 cm)

Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and for 90 days following completion of therapy; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately

A female of child-bearing potential is any woman (regardless of sexual orientation, having undergone a tubal ligation, or remaining celibate by choice) who meets the following criteria:

Has not undergone a hysterectomy or bilateral oophorectomy; or
Has not been naturally postmenopausal for at least 12 consecutive months (i.e., has had menses at any time in the preceding 12 consecutive months)
No prior radiation to the same area
No concurrent chemotherapy
Evaluated by radiation oncologist to be appropriate SBRT candidate and scheduled to undergo SBRT as part of their care
Ability to understand and the willingness to sign a written informed consent

Exclusion Criteria:

Patients with tumors < 1 cm
Patients with nodal disease or distant metastatic disease
Patients may not be receiving any other investigational agents
Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
Patients must not be pregnant
Patients with allergies to iodinated contrast not amenable to pre-medication
Patients who are not able to lie supine with arms raised, and cooperate with breathholding instructions
