Every dated change on the records linked to Ocular adnexal MALT lymphoma, newest first: approvals and regulatory steps on its medicines, trials that reported, guideline versions, milestones, and when this page itself was checked. Dates come from the records; none is inferred. Orientation, not medical advice.
Radiotherapy to the orbit is the standard treatment for disease confined to the ocular adnexa and it controls it in almost everybody. In a series of 28 patients irradiated after a trial of doxycycline, 30 to 36 Gy in 15 to 18 fractions produced a response in all of them and a complete response in 89 per cent, with four-year progression-free survival of 74 per cent and little toxicity beyond three cases of grade 2 cataract and three of grade 1 blepharitis. Very low-dose schedules of about 4 Gy in two fractions are used to spare the lens and the tear gland, with retreatment if the lymphoma returns. Where local series have shown an association with Chlamydia psittaci, a course of doxycycline is a reasonable first step, and the same series shows that trying it first did not cost patients their response to radiotherapy afterwards.
In 28 patients whose lymphoma relapsed or progressed after doxycycline, salvage radiotherapy produced a response in every one and a complete response in 89 per cent, with four-year progression-free survival of 74 per cent.
