Radiotherapy in the Management of Orbital Lymphoma

“…4 This update has expanded the patients included in the analysis from 20 to 44, with a similar in-field local control rate of 98%. This difference in local control rate is due to the method of classifying the patient's recurrence: in the 1999 series, the recurrence was classified as an out-of-field as the patient developed disease in an unirradiated portion of the orbit.…”

“…1,4,[7][8][9][10][11][12][13][14][15][16][17][18][19][20]22,23 Radiotherapy provides excellent local control of disease and should be used as the first-line treatment for primary orbital lymphomas. 20 Radiation therapy alone demonstrates excellent outcomes, especially in low-grade lymphomas, with 92% disease-free survival at 5 years.…”

“…4 The purpose of this series is to report our institution's treatment techniques, disease outcomes, and complication rates after radiotherapy for the management of lymphoma involving the orbit.…”

Lacrimal Gland Radiosensitivity in Uveal Melanoma Patients

“…Orbital RT can result in decreased tear production due to the integral dose received by the lacrimal gland (3)(4)(5)(6)(7). With regard to DES, a clear doseeffect relationship has been reported for whole orbit RT (3)(4)(5)(6)(7)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21). However, current radiation techniques, such as stereotactic RT and intensity-modulated RT, can tailor the dose more precisely to the planning target volume, thereby sparing the lacrimal gland.…”
