Bone marrow reactive T-cell infiltrates have been frequently observed in patients affected by follicular lymphoma after rituximab treatment. In some studies, bone-marrow T-cell expansion has been associated with an effective anti-tumor response and favorable prognosis. In this manuscript, we report on a particularly brisk CD4 T-cell reaction occurring after rituximab treatment for follicular lymphoma and involving the peripheral blood in addition to the bone marrow. Peripheral blood T-cell reaction was mainly composed of effector-memory CD4 T cells and may reflect the expansion of an effective anti-tumor immunity.
在接受利妥昔单抗治疗的滤泡性淋巴瘤患者中,经常观察到骨髓反应性T细胞浸润。在一些研究中,骨髓T细胞扩增与有效的抗肿瘤反应和良好的预后相关。在本手稿中,我们报告了1例在利妥昔单抗治疗滤泡性淋巴瘤后发生的特别活跃的CD4 T细胞反应,该反应除累及骨髓外还累及外周血。外周血T细胞反应主要由效应记忆CD4 T细胞组成,可能反映了有效的抗肿瘤免疫的扩增。
