Linfoma conjuntival

¿Cuál es el Tratamiento para el Linfoma de Células B de Zona Marginal Extranodal Conjuntival Confirmado por Biopsia con Enfermedad Bilateral y sin Compromiso Sistémico?
El linfoma de células B de zona marginal extranodal conjuntival (LZMNE) es una forma de bajo grado y localizada de linfoma de los anejos oculares. Cuando la biopsia histopatológica confirma el diagnóstico y la estadificación revela enfermedad conjuntival bilateral sin compromiso sistémico, se indica un enfoque estructurado de primera línea.
Escenario Clínico
LZMNE conjuntival confirmado por biopsia — afectación conjuntival bilateral, sin diseminación sistémica. El diagnóstico se establece mediante biopsia incisional para examen histopatológico y citológico. La enfermedad conjuntival aislada corresponde a una estadificación localizada (estadio I de Ann Arbor / AJCC T1–T2 N0M0), para la cual el tratamiento locorregional es la consideración principal.

- The gold standard of conjunctival lymphoma diagnosis is an incisional biopsy for histopathological and cytological examination.
- Radiotherapy is the gold standard treatment for lymphoma isolated to the conjunctiva, classified as Ann Arbor stage 1, or T1–T2 (N0M0) according to the AJCC criteria.
- A dose range of 20–30 Gy was long advocated for management of these lesions, however recent literature suggests much lower doses can be used.
- Fasola and colleagues were the first to apply this to OALs in 2013, whereby patients were administered 4 Gy delivered in two 2-Gy fractions on two consecutive days.
- Nuckel and co-workers were the first to employ rituximab at an intravenous dose of 375 mg/m² weekly (for 4 weeks) in 2 patients with orbital disease, with a 50% complete response rate.
- Doxycycline 100 mg twice daily has been shown to be a viable treatment option for T1N0M0 lymphoma with a 5-year progression free survival of 55%, where C. psittaci was confirmed.
- There has been only one report to date describing 6 months of oral Clarithromycin (500 mg twice daily) in relapsed or refractory conjunctival EMZL.
