昨夜看到第529号文献,日本国家癌症中心医院血液科几位专家发表于2010年12月肝脏病杂志的文章,题目与摘要:
Modified cyclophosphamide, vincristine, doxorubicin, and methotrexate (CODOX-M)/ifosfamide, etoposide, and cytarabine (IVAC) therapy with or without rituximab in Japanese adult patients with Burkitt lymphoma (BL) and B cell lymphoma, unclassifiable, with features intermediate between diffuse large B cell lymphoma and BL
Abstract
The feasibility and efficacy of cyclophosphamide, vincristine, doxorubicin, and methotrexate (CODOX-M)/ifosfamide, etoposide, and cytarabine (IVAC) therapy in Japanese adult patients with Burkitt lymphoma (BL) and B cell lymphoma, unclassifiable, with features intermediate between diffuse large B cell lymphoma and BL (intermediate DLBCL/BL) have never been reported. The effects of adding rituximab to CODOX-M/IVAC have not been published either. Fifteen consecutive patients with a median age of 39 years were treated with modified CODOX-M/IVAC regimen (particularly, reducing the dose of methotrexate to 3 g/m(2)) with or without rituximab at our institution. Although all patients developed grade 4 neutropenia and grade 3/4 thrombocytopenia/anemia, 93% had febrile neutropenia, 60% showed transaminase elevation, and 40% had mucositis/stomatitis (all grade 3), there were no treatment-related deaths. Two of nine patients treated with rituximab developed biphasic late-onset neutropenia. Thirteen patients (87%) showed complete responses. The remaining two patients had refractory disease; one had presented with peritoneal dissemination and complex chromosomal abnormalities, while the other had double IGH-MYC and IGH-BCL2 translocations. The estimated 5-year overall and progression-free survival were 87% each, with a median follow-up of 74 months. In conclusion, our modified CODOX-M/IVAC regimen is well tolerated and highly effective in Japanese adult patients with BL and intermediate DLBCL/BL, warranting a larger study for confirmation.

改良CODOX-M/IVAC±美罗华治疗伯基特、不能分类的大B、介于大B和伯基特之间的日本成人患者
摘要
CODOX-M(环磷酰胺,长春新碱,阿霉素和氨甲喋呤)/ IVAC(异环磷酰胺,足叶乙甙,阿糖胞苷)用于治疗Burkitt淋巴瘤(BL)、不能分类的B细胞淋巴瘤、介于弥漫性大B细胞淋巴瘤和BL之间的淋巴瘤(介于DLBCL/ BL),对日本成年患者的可行性和有效性未见报道。美罗华与CODOX-M/IVAC联合使用的效果也尚未公布。我们将改良的CODOX-M/IVAC±美罗华方案(尤其是把甲氨蝶呤剂量降到3克/每平方米)用于连续的15个患者,他们的年龄中位数是39岁。所有患者出现4级中性粒细胞减少和3/4级血小板减少/贫血,93%的患者有发热性中性粒细胞减少,60%的患者转氨酶升高,40%的患者有粘膜炎/口腔炎(均为3级),未出现与治疗相关的死亡。9人中有2人出现利妥昔单抗引起的双相迟发性中性粒细胞减少。 13例(87%)完全缓解。剩下的两个病人有难治性疾病,一个有腹腔扩散和复杂的染色体异常,另一个是IGH-MYC和IGH-BCL2双重易位。中位随访时间为74个月,预计5年总生存率和无进展生存期均为87%。总之,对日本的BL和介于DLBCL/ BL的成年患者,我们的改良CODOX-M/IVAC方案耐受性良好而且高疗效,但需要一个更大的研究进行确认。
部分读后感:
NCCN看来也适用于东亚黄种人,或者说部分囊括了东亚黄种人;
他说减量而不是加量;
“甲氨蝶呤剂量降到3克/每平方米”,现在的成人标准方案的剂量就是这么多(儿童的可能高达5克/每平方米),而成人治疗方案是从儿童的借鉴来的;
年龄中位数39岁,包括了介于大B和伯基特之间的、不能分类的大B这样比较难治的类型,CR率、生存率还这么高;
双重打击的和有其他重病的预后不好;
骨髓抑制严重是普遍现象,患者应有充分思想准备。
病例是收治的连续的患者,未曾挑选,真实性较高,可惜日本患者总数太少,本案只有15例。
