Abstract

Extranodal NK/T cell lymphoma nasal type is an EBV driven non-Hodgkin lymphoma, rare in the United States, with no known satisfactory treatment. Two patients with this entity refractory to CHOP chemotherapy responded to single agent pegaspargase (pegylated L-asparaginase). A 64-year-old Caucasian woman presented with extranodal NK/T lymphoma nasal type on her left buttocks. After initial treatment with loco-regional irradiation and CHOP, she developed extensive lower extremity lesions, and subsequent paranasal sinus involvement. With pegaspargase, she had a dramatic improvement of her skin lesions and proceeded to autologous stem cell transplant. A 48 year old Asian man presented with nasal cavity extranodal NK/T lymphoma which resolved with radiation therapy. Multiple liver lesions which developed while receiving CHOP completely resolved on pegaspargase. L- Asparaginase and its pegylated form have activity in this disease and further exploration alone or in combination is warranted.

摘要

结外 NK/T 细胞淋巴瘤鼻型是一种 EBV 驱动的非霍奇金淋巴瘤,在美国较为罕见,目前尚无已知的满意治疗方法。2 例对 CHOP 化疗耐药的该病患者对单药培门冬酶(聚乙二醇化 L-门冬酰胺酶)有反应。1 例 64 岁白人女性左侧臀部出现结外 NK/T 淋巴瘤鼻型。最初接受局部区域放疗和 CHOP 治疗后,她出现广泛的下肢病变,随后累及副鼻窦。使用培门冬酶后,她的皮肤病变明显改善,并进行了自体干细胞移植。1 例 48 岁亚裔男性患有鼻腔结外 NK/T 淋巴瘤,经放疗后缓解。在接受 CHOP 治疗期间出现的多个肝病变在使用培门冬酶后完全消退。门冬酰胺酶及其聚乙二醇化形式在这种疾病中有活性,单独或联合进一步探索是合理的。
