What is the recommended radiation treatment volume for a patient with orbital DLBCL who achieved a CR to chemotherapy?

When would you treat the entire orbit versus partial orbit? One patient has medial rectus involvement and another has only conjunctival involvement. In cases like these, after a CR, do you treat the entire orbit to 30 Gy?

I suggest consulting the excellent guideline from the ILROG. There is a difference between Primary Intraocular Lymphoma and Orbital (Ocular Adnexal) Lymphoma. The guideline also describes which patients can be managed without irradiation of the entire orbit.
