IMRT for Orbital MALT Lymphoma: A Case Report and a Review of the Literature

Kanyilmaz Gul, Koc Mehmet, Aktan Meryem, Temiz Selami Aykut and Demir Hikmettin

Orbital lymphoma is rare and accounts for less than 1% of non-Hodgkins lymphomas (NHLs) throughout the body. Marginal zone B-cell lymphoma of the mucosa-associated lymphoid tissue (MALT) type ise the most common histological type involving the orbit. MALT lymphomas are indolent, and usually respond well to local radiotherapy (RT). Results from RT series demonstrated excellent and durable local control and survival rates in patients with localized orbital MALT lymphoma. However, due to the rarity of the disease, data about optimal radiation dose from comparative studies are not available and, moreover, in reports with a substantial number of treated patients, doses in the range of 20 and 57 Gy were found to be used. The optimal radiation dose for treating this tumor is controversial. This case is presented because of rare incidence of orbital maltoma and to evaluate the effectiveness of RT in our Radiation Oncology department.
