In patients with early-stage follicular lymphoma undergoing definitive RT, do you approach grade 3a disease any differently than grade 1-2 (radiation dose, fields/margins, systemic therapy)?

Our philosophy is based on whether it is grade 3A or 3B.

If it is 3A, then we treat like low grade lymphoma with RT (similar dose and principle) but if it is 3B, then treat with chemotherapy +/_ RT like diffuse large B cell lymphoma.
