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.

About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

Patients with local symptoms secondary to histologically-confirmed non-small cell lung cancer
Patients who will be receiving palliative-intent external beam radiotherapy
Patients who are clinically appropriate for conventional radiotherapy planning
Patients who can provide written informed consent

Exclusion criteria

Patients who cannot provide written informed consent

Treatment and study plan

CT- simulation scan

Procedure

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
