【 要旨 】 消化管濾胞性リンパ腫(FL)に対する治療は節性FLに準じて行われている.腫瘍の増大速度が遅く,緩徐な経過をたどり,治療奏効性が高いにもかかわらず再発率も高いので,限局期無症状例などではwatch and waitも選択肢となりうる.薬物療法はrituximab単独あるいはrituximab併用CHOP療法による奏効率が高く,ステージの進行した例や有症状例が良い適応となる.寛解後再燃も高率に認めるが,再治療の効果も高く,長期予後が期待できる.本邦の多施設共同研究の結果からは中央値40カ月の観察期間において原病死例はなく5年全生存率および無増悪生存率は100%および93%であった.

[ Summary ] Management of gastrointestinal (GI) follicular lymphoma (FL) is performed based on treatments employed for nodal FL. Due to the slow course of this condition watch and wait is an acceptable option, especially for some asymptomatic patients with localized FL. Immunotherapy, using rituximab with or without the CHOP regimen delivers high treatment efficacy and has been adopted for symptomatic patients with advanced stage FL. Irrespective of high frequency of reccurence after remission, second line treatments are also very effective. Therefore, good prognoses may be expected. In a multicenter, retrospective study including 125 patients with stage I and II1 GI-FL in Japan, during a median follow up of 40 months, no patient died of FL and the over all survival and progression free survival rates after 5 years were 100 % and 93 %, respectively.
