Plasmablastic lymphoma (PBL) is a rare form of non-Hodgkin lymphoma that is highly aggressive and carries a poor prognosis. Although the standard chemotherapy choice for most diffuse large B-cell lymphomas (DLBCL) is R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone), subtypes of DLBCL such as PBL are less responsive to this treatment regimen. The preferred regimens for PBL include infusional EPOCH (etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin hydrochloride), HyperCVAD (cyclophosphamide, vincristine sulfate, doxorubicin hydrochloride, and dexamethasone), or CODOX-M/IVAC (cyclophosphamide, vincristine, doxorubicin, high-dose methotrexate/ifosfamide, etoposide, and high-dose cytarabine). Recent studies have begun to investigate the addition of other agents to these regimens to improve survival. This case report is about a patient with a history of advanced acquired immunodeficiency syndrome (AIDS) with a cluster of differentiation 4 (CD4) count <20 who had CD20 negative plasmablastic lymphoma and was successfully treated with the combination of bortezomib and dose-adjusted EPOCH (V-EPOCH) and intrathecal chemotherapy, achieving complete response with optimal tolerance. To our knowledge, this is the first case to demonstrate a complete response with V-EPOCH for PBL in advanced AIDS with CD4 <20. We aim to highlight the importance of standardizing effective chemotherapeutic approaches to this cancer entity and augment the effectiveness of V-EPOCH therapy in the literature review.
浆母细胞淋巴瘤(PBL)是一种罕见的非霍奇金淋巴瘤,侵袭性很强,预后较差。尽管大多数弥漫性大B细胞淋巴瘤(DLBCL)的标准化疗方案是R-CHOP(利妥昔单抗、环磷酰胺、阿霉素、长春新碱和泼尼松),但DLBCL的亚型如PBL对这种治疗方案的反应较小。PBL的首选方案包括持续静脉输注EPOCH(依托泊苷、泼尼松、长春新碱、环磷酰胺和盐酸阿霉素)、HyperCVAD(环磷酰胺、硫酸长春新碱、盐酸阿霉素和地塞米松)或CODOX-M/IVAC(环磷酰胺、长春新碱、阿霉素、大剂量甲氨蝶呤/异环磷酰胺、依托泊苷和大剂量阿糖胞苷)。最近的研究已开始探讨在这些方案中添加其他药物以提高生存率。本病例报告的是一名有晚期获得性免疫缺陷综合征(AIDS)病史、分化簇4(CD4)计数<20且患有CD20阴性浆母细胞淋巴瘤的患者,该患者通过硼替佐米与剂量调整后的EPOCH(V-EPOCH)联合鞘内化疗成功治愈,实现了完全缓解且耐受性良好。据我们所知,这是第一例在CD4<20的晚期AIDS患者中使用V-EPOCH治疗PBL获得完全缓解的病例。我们旨在强调对这种癌症实体标准化有效化疗方法的重要性,并在文献综述中增强V-EPOCH疗法的有效性。
