Abstract

In ALK-negative anaplastic large cell lymphoma (ALCL), gene rearrangements of and are considered mutually exclusive. The former predicts a favorable prognosis, while the latter is generally unfavorable. We report the first case of ALK-negative ALCL in a leukemic phase with small cell pattern transformation, harboring double-hit rearrangements of the gene by inv(6)(p25q21) and gene by TBL1XR1-TP63 inversion. Despite the resistance to chemotherapies, the patient remained in remission with allogeneic stem cell transplantation over 20 months. Recognizing this pathologically and genetically rare condition is needed for prompt diagnosis and therapeutic decision-making in ALK-negative ALCL.

摘要

在ALK阴性间变性大细胞淋巴瘤(ALCL)中, 和 的基因重排被认为是相互排斥的。前者预示着良好的预后,而后者通常预后不佳。我们报告了首例处于白血病期且伴有小细胞模式转化的ALK阴性ALCL病例,该病例存在因inv(6)(p25q21)导致的 基因和因TBL1XR1 - TP63倒位导致的 基因的双打击重排。尽管对化疗耐药,但该患者通过异基因干细胞移植在20多个月的时间里一直处于缓解状态。对于ALK阴性ALCL的快速诊断和治疗决策而言,认识到这种病理和基因罕见的情况是必要的。
