The purpose of this study is to determine the optimal radiation dose fractionation regimen for low grade follicular lymphoma. It is hypothesized that the complete response rate with the use of 12 Gy in 6 daily fractions is 80% (10% total width of the confidence interval) at 3 months. This phase II study will evaluate whether an intermediate dose for follicular lymphoma is associated with excellent response rates while minimizing acute and late toxicity.

RECRUITINGComplete response within the radiated volume at 1month post radiation
Participants will be assessed for response at 1 month (primary outcome) and then 3 months following completion of radiotherapy, clinically or radiographically, as appropriate. Complete response is defined as absence of detectable disease in the radiated volume. Partial response is 50% or more reduction in the volume of disease in the radiated volume. Overall response is defined as complete and partial response. Stable disease is defined as no change in the irradiated tumour or less than 50% reduction. Progressive disease is defined as enlargement of the irradiated tumour
Time frame: 1 month
Overall survival, progression-free survival and toxicity
Toxicity (6) will be scored according to the Common Terminology Criteria for Adverse Events (CTCAE) definitions (site specific modules), at 1 month and then 3 months following completion of radiotherapy.
Time frame: 1 month and 3 month
