Single Pulmonary Nodule Investigation (SPUtNIk)
A small proportion of patients with lung cancer present with a solitary pulmonary nodule (SPN), this is a single spot on a CT scan. This is an important group of patients because if it is lung cancer, presentation as a SPN represents early disease, which following surgery has a high 5 year survival rate. However as not all SPNs are lung cancer it would be unethical to biopsy every case. Clinical guidelines recommend that SPNs should undergo an initial fluorodeoxyglucose (FDG)-PET/CT scan, which may give more information about the SPN and may indicate that it is likely to be lung cancer. However in many cases it does not and current practice is to monitor the SPN with a series of CT scans over 2 years to look for changes or growth which may/ but not always indicate lung cancer. If no changes are observed over 2 years the SPN is considered not lung cancer. This is both expensive for the National Health Service (NHS) and worrying for the patient in terms of monitoring CT costs and delayed treatment due to length of time to diagnosis.
In this study the investigators propose to examine the diagnostic capacity of initially using a different CT scan Dynamic Contrast Enhanced -CT(DCE-CT). DCE-CT and FDG-PET/CT scans give different information about the SPN and the investigators will look to see if information from either scan or combined information from both scans may be better in the diagnosis of early stage lung cancer.
The investigators will also undertake a review of previous studies that have been done using these scans in the diagnosis of lung cancer and use data from both the review and the trial to look at the cost effectiveness of using DCE-CT in the diagnosis of SPN.
The investigators hope to recruit 375 people who have a SPN detected by a normal CT scan. These patients will normally be offered a FDG-PET/CT scan and if they participate in this study they will also receive a DCE-CT scan either on the same day or within two weeks of the FDG-PET/CT scan. This is the only extra procedure that will take place to normal NHS care, however patients will sign a consent form to give us permission to use data from any future CT scans or biopsies and any diagnosis that they may have over the next two years.
The study is coordinated by the clinical trials unit at Southampton University.
Recruitment began in January 2013. Patients will be recruited from 10 centres throughout the UK where they will be treated locally. The investigators expect recruitment to last until late 2014 and patient's medical data to be followed for another 2 years.
The investigators expect to have completed the analysis and made conclusions about the usefulness and cost effectiveness of DCE-CT scans in the diagnosis of early stage lung cancer in SPN.
The study is funded by the Health Technology Assessment arm of the National Institute for Health research, which is government funded.

Time Perspective: Prospective
|Official Title:||Accuracy and Cost-Effectiveness of Dynamic Contrast Enhanced Computed Tomography in the Characterisation of Solitary Pulmonary Nodules|
- Effectiveness of DCE-CT scans and FDG-PET scans to diagnose early lung cancer in SPN [ Time Frame: 2 years ] [ Designated as safety issue: No ]Primary outcome measures will include diagnostic test characteristics (sensitivity, specificity, accuracy) for 18FDG-PET/CT and DCE-CT in relation to a subsequent clinical diagnosis of lung cancer.
- cost effectiveness of using DCE-CT scans in the diagnosis of early lung cancer in SPN [ Time Frame: 2 years ] [ Designated as safety issue: No ]The outcome measures used in the economic model will include accuracy, estimated life expectancy, and quality adjusted life years (QALYs). Costs will be estimated from an NHS perspective. Incremental cost-effectiveness ratios will compare management strategies with DCE-CT to strategies without DCE-CT.
- Effectiveness of DCE-CT scans combined with FDG-PET scans to diagnose early lung cancer in SPN [ Time Frame: 2 years ] [ Designated as safety issue: No ]Diagnostic test characteristics combined DCE-CT/18FDG-PET in relation to a subsequent clinical diagnosis of lung cancer.
- Effectiveness of using analysis of the CT image from the FDG-PET/CT in conjunction with data from the FDG incorporation to diagnose early lung cancer in SPN [ Time Frame: 2 years ] [ Designated as safety issue: No ]Diagnostic test characteristics for 18FDG-PET/CT with incorporation of CT appearances in relation to a subsequent clinical diagnosis of lung cancer.
