中文摘要
一名69岁男性急性早幼粒细胞白血病患者处于分子学缓解状态,外周血细胞中未检测到PML::RARA转录本,随后发生急性中耳炎。10个月后,因怀疑继发性胆脂瘤而施行鼓室乳突切除术。组织学检查证实为PML::RARA阳性细胞浸润的髓外复发。患者在接受三氧化二砷治疗后达到第二次分子学缓解。我们的发现提示:(1)诊断样本可从乳突气房而非中耳腔获取;(2)分子学缓解并不排除髓外复发;(3)全反式维甲酸与三氧化二砷联合治疗可能降低髓外复发的风险。
英文摘要
A 69-year-old man with acute promyelocytic leukemia in molecular remission and no detectable PML::RARA transcripts in his peripheral blood cells developed acute otitis media. After 10 months, tympanomastoidectomy was performed for suspected secondary cholesteatoma. A histological examination confirmed extramedullary relapse with PML::RARA-positive cell infiltration. The patient achieved a second molecular remission after treatment with arsenic trioxide. Our findings suggest that (1) a diagnostic sample may be obtained from mastoid air cells rather than from the middle ear cavity, (2) molecular remission does not preclude extramedullary relapse, and (3) all-trans retinoic acid and arsenic trioxide combination therapy may reduce the risk of extramedullary relapse.
