Description of intervention(s) / exposure
Stereotactic ablative body radiotherapy
Patients will be assigned to 1 of 3 treatment arms, dependent on site of the lesion.
1. Peripheral lesions:
- Tumour GTV less than 1.5 cm from ribs: 48 Gy in 4 fractions (12Gy/#)
- Tumour GTV greater than or equal to1.5 cm from ribs: 54 Gy in 3 fractions (18Gy/#)
2. Central lesions:
- 50 Gy in 5 fractions (10Gy/#)

Two to three treatments are to be delivered per week. There must be a minimum break of 1 day and a maximum break of 4 days between fractions. The following applied to the treatment delivery times:
3 fraction regimens to be delivered within 11 days
4 fraction regimens to be delivered within 14 days
5 fraction regimens to be delivered within 14 days

Key inclusion criteria
Diagnosis of non-small cell lung cancer
-Pathological diagnosis is desirable where this can be achieved.
-Diagnosis based on imaging: requires evidence that lesion(s) are increasing in size on 2 consecutive CT scans and /or increased uptake on PET.

Stage T1-T2, N0M0 (AJCC Staging, 6th ed.) with tumour size less than or equal to 5 cm, based upon:
-History and physical examination 4 weeks prior to registration.
-CT chest, abdomen and pelvis and/or
-FDG PET-CT scan

ECOG performance status of less than or equal to 2

Patients must be able to lie flat and comply with the requirements of simulation and treatment.

Patients with previous thoracic radiotherapy are permitted, provided V20 less than 15% on previous treatment an no overlap with intended current radiotherapy field

Patients with previous history of malignancy may be included provided the previous malignancy is in remission and after a MDT discussion the current lung lesion is thought to be more likely of lung primary rather than metastatic disease

Type of endpoint(s)
Statistical methods / analysis
The primary end point, local control at 24 months from start of treatment, is used for sample size calculation. Prior data indicate that the probability of local recurrence amongst cases receiving the historical standard treatment (3D-Conformal radiotherapy from 60 to 70 Gy) is 0.65. This estimate of local control from historical techniques is conservatively high, and other studies have shown local control rates under 50%. A sample size of 85 will allow the detection of a 15% difference in local control rates to 65% from those of historical data (50%), with a significance level of 5% and power of 80%. Allowing for an approximate 15% drop-out rate for follow-up, we will recruit approximately 100 patients. Based on estimated recruitment form centres currently treating SABR lung cancer, this sample size should be easily achievable. STATA SE version 11 was used for sample size calculation (one sample). Proportions for local control at 24 months will be described as percentage with 95% CI.

Analysis for secondary endpoints will be descriptive.

Brief summary
This study aims to investigate the efficacy of stereotactic ablative radiation therapy for treatment of Stage I non-small cell lung cancer. Who is it for? You may be eligible to join this study if you are aged 18 years or above and have a diagnosis of Stage I non-small cell lung cancer. You must be able to lie flat and comply with the requirements of simulation and treatment. Participants in this study will be treated with stereotactic ablative radiation therapy with one of three dose and fractionation regimens. For peripheral lesions treatment dose will be 48 Gy in 4 fractions or 54 Gy in 3 fractions, depending on tumour size. For central lesions 50 Gy will be administered in 5 fractions. Overall treatment duration will vary from 11 – 14 days. Local control at 24 months is the primary endpoint of the study and is assessed by CT scans. Patients will be followed up until 5 years post treatment. A total of 100 patients will be recruited in this study.
