Eligibility Criteria
Inclusion
- Age between 18 to 75 years old.
- Meets the WHO diagnostic criteria for ocular adnexal MALT lymphoma, with a comprehensive diagnosis based on pathology (including pathological morphology, immunophenotype, and genetic testing), clinical manifestations, and biological characteristics:
- Clinical criteria: ① Extranodal lymphoma occurring in the ocular adnexa; ② Localized mass.
- Pathological criteria:
- <!-- -->
- Histopathology: Morphological features that recapitulate Peyer's patches, including: ① Lymphoepithelial lesions; ② Reactive follicles; ③ Marginal zone cells and/or monocytoid B cells; ④ Small lymphocyte-like cells; ⑤ Plasma cells; ⑥ Scattered transformed blasts (centroblast-like, immunoblast-like cells).
- Immunophenotype: Tumor cells express B-cell-related antigens: SIgM+, CIg +/-, CD5-, CD10-, CD23-, cyclin DI, CD43 +/-, CD19, CD20, CD22, and CD79a positive.
- Genetic features: Absence of BCL-1 and BCL-2 gene rearrangements, presence of IgH/L gene rearrangements; possible +3 and t(11, 18)(q21, q21).
- Based on the TNM staging of ocular adnexal lymphoma, patients with stages T1-3 of ocular adnexal MALT lymphoma are included.
- Informed and signed informed consent.
Exclusion
- Based on the TNM staging of ocular adnexal lymphoma, patients staged as T4 of ocular adnexal MALT lymphoma.
- 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.
- Concurrent other ocular diseases: Including corneal abnormalities or existing corneal infections, iridocorneal endothelial syndrome, anterior segment dysgenesis, true microphthalmos, uveitis, glaucoma, ocular trauma, and retinal disorders such as central retinal vein occlusion, central retinal artery occlusion, retinal detachment, etc.
- Need for long-term use of local or systemic steroids.
- Patients already enrolled in other drug clinical trials.
- Pregnant or breastfeeding women.
- Serious systemic diseases: Advanced cardiac disease, kidney disease, respiratory diseases, or other malignant tumors, etc.
- Inability to understand the research content.
- If both eyes of a patient meet the inclusion criteria, the right eye will be selected for participation in the study, while the left eye will receive the same treatment, but its data will not be included in the research. Each patient can have only one eye participating in the study.
