  Purpose

This clinical trial studies 4-dimensional (4-D) image-guided radiation therapy treatment planning in patients with stage I-IV non-small cell lung cancer. Computed tomography (CT) scans and treatment-planning systems may help in planning radiation therapy for patients with non-small cell lung cancer.

Enrollment: 22
Study Start Date: September 2006
Estimated Study Completion Date: June 2019
Estimated Primary Completion Date: April 2019 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Diagnostic (radiation therapy planning)
Patients undergo placement of one or more small radio-opaque markers or electromagnetic transponders into (or in the vicinity of) the primary lesion or suspect lymph nodes via bronchoscopy. Patients then undergo 4-D CT imaging prior to radiotherapy sessions and once a week at the end of treatment.

Detailed Description:

OBJECTIVES:

  • Quantify the magnitude and distribution of inter- and intrafraction anatomic variations, including the temporal stability of the tumor/respiration signal correlation.
  • Improve the acquisition and reconstruction of 4D CT scan images by advancing the 4D CT scan data collection process and evaluating 4D CT scan image reconstruction using different respiratory inputs.
  • Quantify the uncertainty of deformable image-registration algorithms.
  • Develop and investigate the efficacy of inter- and intrafraction probabilistic planning-based 4D image-guided adaptive radiotherapy (IGART) strategies for clinical application.
  • Determine the expected geometric, dosimetric, and radiobiological improvements from the 4D IGART system.

OUTLINE: Patients undergo insertion of ≥ 1 small radio-opaque marker into (or in the vicinity of) the primary lesion or suspect lymph nodes via bronchoscopy. X-rays are performed to document the position of the markers.

Patients undergo 4D CT scan before each radiotherapy session and once a week after a radiotherapy session. Patients also undergo x-ray imaging before and during radiotherapy, optical and internal marker motion recording before and after radiotherapy, and audiovisual feedback during radiotherapy.

Patients undergo image-guided adapted radiotherapy based on these data.
