Spots Global Cancer Trial Database for Computed Tomography Assessment of Regional Ventilation (CURVE)

Study Description

Brief Summary: This study uses CT scans to assess airflow in the lung, the scan is quick, cheap and painless. The information from the scan may help doctors tell which patients are suitable to have surgery to cure early stage lung cancer. It may also help doctors tell which patients would benefit from surgery for emphysema and diagnose types of lung disease. The investigators will follow up patients who go through surgery to test how well the scan predicts the function of the lung after surgery. The investigators will follow patients being investigated for lung disease to test how accurate the scan is at the getting the diagnosis right.

Detailed Description: CT scans during breathing in and breathing out (CTPVe) can assess regional airflow within the lung, using newly developed software as described by Aliverti et al. This provides information about the function of each part of the lung. The investigators aim to assess the feasibility of a larger trial using CTPVe to guide treatment of lung diseases and develop the statistical models needed for use in these trials. Surgery provides the best prospect of a cure in early Non-small cell lung cancer. In the UK only half of people with early lung cancer undergo surgery and poor lung function may be a barrier to removal of part of the lung. Many patients with lung cancer also have emphysema or other lung diseases that reduce lung function. Actual post-operative lung function is often better predicted by current methods. The investigators will assess regional airflow in the lung and compare the airflow to the patients lung function both before and after surgery to assess if CTPVe can predict postoperative lung function, enabling more people to be considered suitable for curative surgery, Severe emphysema is debilitating, some surgical treatments can improve the symptoms of emphysema; these include lung volume reduction surgery, endobronchial valves and endobronchial coils. Each of these are only suitable for certain patients and it is difficult to predict who will benefit most. The investigators will assess regional airflow in the lung and compare the airflow to the patients lung function before and after these treatments for emphysema to assess if CTPVe can predict who will benefit from surgery. There are hundreds of subtypes of interstitial lung disease that respond to different types of treatment but diagnosing the subtype can be very difficult. Patients may need to undergo surgery to get the diagnosis of their subtype and this is associated with major risks, including death. The investigators will assess the regional airflow in the lung and compare the pattern to the final subtype of interstitial lung disease to assess if CTPVe could mean future patients do not need surgery for diagnosis.
