摘要目的 探讨套细胞淋巴瘤(Mantle Cell Lymphoma,MCL)患者的临床特征、不同治疗方案的疗效及预后因素.方法 回顾性分析2000年1月至2010年3月在四川大学华西医院住院治疗的37例MCL患者的临床特征及不同治疗方案的疗效,并进行相关预后因素分析.结果 37例患者中位发病年龄62岁,男女比例2.7∶1,Ann Arbor分期为Ⅰ～Ⅱ期者l例(2.70%)、Ⅲ～Ⅳ期者36例(97.30%),有B症状者20例(54.05%),结外起病者16例(43.24%),有骨髓侵犯者24例(64.86%),脾肿大者11例(29.73%),淋巴细胞绝对值升高者9例(24.32%),乳酸脱氢酶(LDH)升高者19例(51.35%);22例患者进行了Ki-67值检测,Ki-67值≤40%者占68.18%、＞40%者占31.82%;利妥昔单抗联合化疗者总有效率92.31%,高于CHOP样方案(46.15%)及CHOP+干扰素方案(42.86%),且3年总生存(OS)率及无进展生存(PFS)率均优于后二种方案(P＜0.05).脾肿大、白细胞升高、淋巴细胞绝对值升高及Ki-67值＞40%为预后不良因素.结论 MCL患者多为老年起病,男性多见,易有骨髓受累,预后差,利妥昔单抗联合化疗可提高治疗有效率,改善患者生存.

abstractsObjective To analyze clinical features, therapeutic effects and prognostic factors of patients with mantle cell lymphoma (MCL). Methods Clinical data of 37 MCL patients hospitalized in our hospital from January 2000 to March 2010 were retrospectively analyzed. Results The median age was 62,with a male predominance. 97.30% of the patients were in Ann Arbor stage Ⅲ～Ⅳ ,54.05% with B symptoms,64.86% with bone marrow involvement, 29.73% with splenomegaly, 24.32% with lymphocytosis and 51.35% with elevated LDH. Ki-67 was detected in 22 cases,and patients with Ki-67 ≤40% accounted for 68.18%. Of 37 cases, the overall response rate (ORR) of rituximab combined with chemotherapy was 92.31%, being higher than those of CHOP (46.15%) and CHOP + IFN (42.86%) regimens. There were statistical differences in the 3-year progression-free survival (PFS) and overall survival (OS) between rituximab + chemotherapy and CHOP or CHOP + interferon regimens (P ＜0.05, respectively). Splenomegaly, elevated WBC, lymphocytosis and Ki-67 ＞ 40% were identified as adverse prognostic factors. Conclusion Most patients with MCL were older adults, with a male predominance and usually had bone marrow involvement and poor prognosis. Rituximab combined with chemotherapy could improve ORR and OS of MCL.
