要約 目的:眼付属器リンパ腫の治療成績の報告。対象と方法:過去10年間に眼付属器のリンパ腫と診断され,治療をした19症例を対象とした。男性15例,女性4例で,年齢は25~84歳(平均58歳)である。7例が結膜型,12例が眼窩型であった。びまん性大細胞型B細胞リンパ腫の眼窩型1例を除き,全例がMALTリンパ腫であった。結果:結膜型の全例が放射線治療で治癒した。眼窩型の若年者では放射線治療のみでは寛解せず,化学療法や抗モノクローナル抗体(リツキシマブ)が奏効する例があった。結論:若年者の眼窩型MALTリンパ腫で,放射線治療に抵抗または再増悪する例では,早期から化学療法やリツキシマブが奏効することがある。
Abstract. Purpose:To report the outcome of treatment for malignant lymphoma of the ocular adnexa. Cases and Method:This retrospective study was made on 19 cases of malignant lymphoma of the ocular adnexa diagnosed and treated during the past 10 years. The series comprised 15 males and 4 females. The age ranged from 25 to 84 years,average 58 years. Malignant lymphoma involved the conjunctiva only in 7 cases and extended into the orbit in 12 cases. All were diagnosed with MALT lymphoma except one case of diffuse large B-cell lymphoma of the orbit. Results:Cure was obtained in all the cases of conjunctival type after radiation therapy. Some young of orbital type resisted radiation therapy and had to be treated by chemotherapy or anti-monoclonal antibody(rituximab)to achieve improvement. Conclusion:Malignant lymphoma of the orbit in young persons may prove resistant to or recur after radiation therapy. These cases may need chemotherapy or rituximab from early stage of the disease.
