Study type
Interventional
Description of intervention(s) / exposure
Treatment: Other - Stereotactic Body Radiotherapy

Other: Group 1 - This group of 12 patients will be given 36Gy of Stereotactic Body Radiotherapy (SBRT) divided into six separate doses. This will be delivered two to three time per week.

Other: Group 2 - This group (12 patients) will be given 38Gy of Stereotactic Body Radiotherapy (SBRT) divided into six separate doses. This will be delivered two to three time per week.

Other: group 3 - This group (12 patients) will be given 40Gy of Stereotactic Body Radiotherapy (SBRT) divided into six separate doses. This will be delivered two to three time per week.


Treatment: Other: Stereotactic Body Radiotherapy
Each group will have different dose of stereotactic body radiotherapy (SBRT). Depending on which group patients are in.

Outcomes
Primary outcome [1] 0 0
feasibility of SBRT dose escalation. This will be assessed by the number of participants with grade 3 acute toxicity according to CTCAE version 4.3
Timepoint [1] 0 0
at weekly review through completion of each radiothrapy dose level, approximately one year
Primary outcome [2] 0 0
safety of SBRT dose escalation. This will be assessed by the number of participants with grade 3 acute toxicity according to CTCAE version 4.3
Timepoint [2] 0 0
at weekly review through completion of each radiothrapy dose level, approximately one year
Primary outcome [3] 0 0
Toxicity. This will be assessed by the number of participants with grade 3 acute toxicity according to CTCAE version 4.3 and RTOG toxicity score.
Timepoint [3] 0 0
at weekly review through completion of each radiothrapy dose level, approximately one year
Secondary outcome [1] 0 0
Tolerability of conservation dose escalation in this cohort of patients
Timepoint [1] 0 0
After each group of patients have completed radiotherapy and at 12 and 24 months follow-up. Patients will have routine follow-up 6 monthly for 1 year and then yearly for 10 years post treatment. But study outcomes will only be collected for 2 years.

Eligibility
