概述
Orbital lymphoma is a type of non-Hodgkin lymphoma that arises in the tissues surrounding the eye, including the eyelids, lacrimal gland, and orbit. The most common subtype is extranodal marginal zone B-cell lymphoma (MALT type).
症状
- Painless orbital mass or swelling
- Protrusion of the eye (proptosis)
- Vision changes or double vision
- Restricted eye movement
- Eyelid drooping or fullness
病因与风险因素
- Chronic inflammation (e.g., autoimmune diseases or infections like Chlamydia psittaci)
- Older age
- Immunosuppression
- History of lymphoma or related blood cancers
诊断方法
- Ophthalmic and physical exam
- Orbital imaging (CT, MRI)
- Biopsy with immunohistochemistry and flow cytometry
- Systemic workup: blood tests, bone marrow biopsy, PET/CT scan
治疗方案
- Radiation therapy (mainstay for localized disease)
- Chemotherapy (e.g., rituximab-based regimens for systemic or advanced cases)
- Antibiotic therapy (e.g., doxycycline for C. psittaci-related cases in some regions)
- Immunotherapy and targeted agents in recurrent disease
预后情况
- Generally favorable for localized MALT lymphoma
- 5-year survival often >90% in early-stage cases
- Risk of systemic progression in some cases; long-term monitoring is important
与此类癌症共处
- Regular ophthalmic and oncologic follow-up
- Visual rehabilitation if necessary
- Support for dry eye or cosmetic changes post-radiation
- Psychosocial care
预防与筛查
- No standard prevention
- Early evaluation of orbital or eyelid swelling
- Monitoring for recurrence in previously treated patients
FAQs
Q: Is orbital lymphoma curable?
A：Yes, especially if diagnosed early and treated with localized radiation.
Q: Will I lose vision or my eye?
A：Unlikely with timely treatment, but symptoms should be monitored.
Q: Is it related to systemic lymphoma?
A：It can be. Systemic evaluation is part of the diagnostic process.
