CT-Based Versus Conventional Simulation for Palliative Radiotherapy of Non-Small Cell Lung Cancer

Radiotherapy (RT) treatment to the chest is a standard way of trying to decrease symptoms like cough or shortness of breath. Before any RT can be delivered, it must be planned, either using conventional x-rays ("fluoroscopy") or using computer tomography ("CT") scanning. This study is being done because the investigators do not know which of these two common ways of RT planning is better for balancing both treating the cancer and decreasing side effects.

Condition Intervention
Non-small Cell Lung Cancer Procedure: CT- simulation scan

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Cross-Sectional
Official Title: Comparison of Two-versus Three-Dimensional Treatment Planning for Patients Receiving Chest Radiotherapy for Symptom Control

Estimated Enrollment: 20
Study Start Date: April 2009
Study Completion Date: January 2011
Primary Completion Date: January 2011 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Study Cohort
Procedure: CT- simulation scan
Patients who are receiving standard palliative radiotherapy planned under x-rays will also undergo 1 CT-simulation scan which they would otherwise not require. The planning x-rays and CT scan will then be compared dosimetrically

Detailed Description:
Standard RT planning will be performed under conventional simulation, followed by CT-simulation (for study purposes only). Retrospectively, 3D treatment fields will be designed using the CT-simulation data, and compared to the actual treatment fields planned using x-rays. Coverage of the tumour volume will be assessed, together with doses, field sizes and beam positions, to determine relative undercoverage of tumour and overcoverage of normal tissue between the two planning methods, if any.
