Lung Tumour Volume Database

Patients with locoregional non small cell lung cancer are registered on study after tumour volumes are outlined by a radiologist and prior to the commencement of any treatment.

All patients must have recorded the volume of disease in the primary tumour (and of involved nodes > 1 cm diameter) as measured from a CT scan performed according to a standard set of conditions.

Following registration patients are treated with Definitive radiotherapy with or without chemotherapy. Follow-up will occur with the collection of a minimum amount of data every 12 months from the date of registration on study.

Quality Assurance procedures will be implemented with each site that participates in the study.

Inclusion criteria

Must satisfy ALL of the following

• NSCLC - histological or cytological diagnosis of non-small cell lung cancer

• CT planning - CT imaging of the thorax has been performed as part of the planning procedure
• Definitive radiotherapy - it is planned to give definitive radiotherapy with or without chemotherapy (prior to, during or after radiotherapy). Definitive radiotherapy is defined as 60 Gy in 6 weeks, 50 Gy in 4 weeks or at least the equivalent of either of these. The size of each individual; fraction should not exceed 2.5 Gy.
• Measurable disease - the primary tumour and nodes with maximum diameter greater than 1cm represent measurable disease
