Second cancers and particularly postransplant lymphoproliferative disorders (PTLDs) are extremely rare in patients undergoing autologous peripheral blood stem cell transplantation (auto-SCT). We report the case of clonally rearranged T-cell expansion which occurred after auto-SCT for Multiple Myeloma (MM). Does asymptomatic clonal T-cell large granular lymphocytic proliferation, in our experience, represent either a secondary cancer after auto-SCT or clonal T cell aberration or derive from expansion of coexisting undetected small-sized clone of T cells?
在接受自体外周血干细胞移植(auto-SCT)的患者中,二次癌症尤其是移植后淋巴细胞增殖性疾病(PTLD)极为罕见。我们报告了一例多发性骨髓瘤(MM)患者在自体造血干细胞移植后发生克隆性重排的T细胞扩增的病例。根据我们的经验,无症状的克隆性T细胞大颗粒淋巴细胞增殖是自体造血干细胞移植后的二次癌症、克隆性T细胞畸变,还是源于未被检测到的共存小尺寸T细胞克隆的扩增?
