[Role of modified radiotherapy in the combined treatment of orbital non-Hodgkin lymphoma].

The study included 36 patents (primary tumor--27, recurrent orbital lymphoma--9) with diagnosed non-Hodgkin's orbital or conjuctival lymphoma treated at the Center's Clinic (1999-2007). All patients received an average multifractionated dose of 34.5 Gy from the S1-75-5 linear electron accelerators (Philips) generating 6 MeV of braking radiation. Also, the Elekta Precise with a multi-lobe collimator (6 and 18 MeV of braking and 4-20 MeV of electron radiation) was used. Relevant radiotherapy was given to 3 patients while conventional one--to the rest of the group: CHOP chemoradiotherapy--24, R-CHOP--3. Complete local response was reported in all patients (100%). Early-onset radiation-related complications presented mainly as conjunctivitis (22). Late-onset ones were cataract and dry eye (5) (13.9%).
