摘  要:目的观察套细胞淋巴瘤(MCL)患者的临床特征并探讨预后相关因素。方法回顾性分析23例MCL患者的临床资料,并采用免疫组化检测12例MCL患者的Mcl一1、磷酸化(p)NF—id3p65和14.3.3(蛋白的表达,分析预后相关因素。结果23例MCL患者中,国际预后指数(IPI)0~2分17例(73.9%),3-4分6例(26.1%),前者2年无进展生存(PFS)率优于后者(47.1%对0,P=-0.049);MCL国际预后指数(MIPI)〈5.7分16例(69.5%),总反应率(ORR)、2年总生存(OS)率及PFS率均优于MIPI≥5.7组患者(7例)(ORR:81.3%对33.3%,P=-0.032;OS:68.8%对16.7%,P=0.041;PFS:50.0%对0,P=0.040)。利妥昔单抗(R)+CHOP(E)[阿霉素、环磷酰胺、长春新碱、泼尼松(依托泊苷)]方案组ORR、2年OS及PFS率分别为100.0%、80.0%及70.0%,均优于cHOP(E)方案组(分别为38.5%、30.8%及7.7%)(尸值分别为0.002、0.024、0.003)。12例患者中6例Mcl-1阳性,其中2例短期治疗有效[完全缓解(cR)+部分缓解(PR)],随访2年存活,1例随访2年持续CR;而Mcl-1阴性患者均达CR,随访2年存活,5例随访2年持续CR/PR。6例pNF.KBp65阳性患者中3例短期治疗有效,随访2年存活,1例随访2年持续CR;而6例pNF-κBp65阴性患者5例达到CR,随访2年持续CR/PR。8例14—3—3ζ阳性患者中5例治疗有效,4例随访2年存活,3例随访2年持续CR/PR;4例14.3.3‘阴性患者3例达到CR,4例随访2年存活,3例随访2年持续CR/PR。结论MCL患者异质性明显,MIPI较IPI具有更好的预后判断意义。R+CHOP(E)方案较CHOP(E)方案疗效好。Mcl-1、pNF.vd3p65、14.3—3(蛋白表达可能与MCL预后有一定关系。Objective To investigate the clinical characteristics and prognostic factors of mantle cell lymphoma (MCL) patients. Methods The clinical data of 23 MCL patients were retrospectively analyzed. Immunohistochemical stain was performed to detect the protein expressions of Mcl-1, pNF-κB p65 and 14-3-3ζ of MCL patients to analyze its prognostic factors. Results Among 23 MCL patients, there were 17(73.9%) patients with IPI 0-2 (low risk group) and 6(26.1%) patients with IPI 3-4. Only the rate of 2y-progression- free survival (PFS) of group IPI 0-2 was superior to that of group IPI 3-4 patients (47.1% vs 0, P=-0.049); There were 16 (69.5%) patients with MIPI 〈 5.7, whose rates of overall response rate (ORR), 2y overall survival (OS) and PFS were better than those of the ones with MIPI t〉 5.7 (ORR: 81.3% vs 33.3% P=0.032; OS: 68.8% vs 16.7% P=0.041; PFS: 50% vs O, P=0.040 respectively). The rates of ORR, 2y-OS and 2y-PFS ( 100.0%, 80.0% and 70.0%) ofpatienets received regimen R+CHOP (E) were all superior to those (38.5%, 30.8% and 7.7%) of ones received regimen CHOP(E)(P=0.002, P= 0.024, P=0.003, respectively). Among 12 patients, 2 out of 6 cases with Mcl- 1 positive expression achieved good response (CR+PR) and 2y-OS, 1 case 2y-PFS; All 6 cases with Mcl-1 negative expression achieved good response (CR+PR) and 2y-OS, 5 cases 2y-PFS. 3 out of 6 cases with pNF-r,B p65 positive expression achieved good response (CR+PR) and 2y-OS, 1 case 2y-PFS; 5 out of 6 cases with pNF-r,B p65 negative expression achieved good response (CR+PR) and 2y-OS/PFS. 5 out of 8 cases with 14-3-34 positive expression achieved good response (CR+PR), 4 cases 2y-OS, and 3 cases 2y-PFS. 3 out of 4 cases with 14-3-34 negative expression achieved CR, 4 cases 2y-OS, and 3 cases 2y-PFS. Conclusion MCL patients had high heterogeneity. MIPI has better prognostic significance than IPI. R+CHOP (E) as first line treatment improved the rates of OS/PFS. Th
