CT-Based Versus Conventional Simulation for Palliative Radiotherapy of Non-Small Cell Lung Cancer
- Conditions
- Non-small Cell Lung Cancer
- Interventions
- Procedure: CT- simulation scan
- Registration Number
- NCT00862030
- Lead Sponsor
- Alberta Health services
- Brief Summary
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.
- 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.
