This project proposes to establish a prospective, multicenter, randomized, controlled clinical study to compare the safety and efficacy of Intralesional Rituximab Injection versus Involved Site Radiation Therapy for the treatment of primary ocular adnexal MALT lymphoma. The aim is to provide high-level clinical evidence for the treatment of ocular adnexal MALT lymphoma and to offer patients treatment options that have fewer complications and comparable therapeutic effects.
Age between 18 to 75 years old.
Ocular adnexal MALT lymphoma with a comprehensive diagnosis based on pathology, clinical manifestations, and biological characteristics according to the WHO classification of tumors of hematopoietic and lymphoid tissues.
Based on the TNM staging of ocular adnexal lymphoma, patients with stages T1-3 of ocular adnexal MALT lymphoma without involvement of intraconal compartment are included.
Willing to participate the trial and sign the informed consent form.
Based on the TNM staging of ocular adnexal lymphoma (Table 1), patients staged as T2/T3 with involvement of intraconal compartment and patients staged as T4.
Patients who have previously received local or systemic radiation, chemotherapy, or drug treatment specifically for ocular adnexal MALT lymphoma.
Presence of cataract and is anticipated to require surgical treatment within a certain period after enrollment; existing cataract affects visual field testing and fundoscopic examination; vision affected by cataract is <20/40.
In addition to the need for treatment of ocular adnexal MALT lymphoma, there is a requirement for other ocular procedures (e.g., full-thickness corneal transplant or retinal surgery) or an anticipated need for another emergent ocular surgery.
