BCL-2/Bax ratio is the main director of apoptosis in CLL. The study aimed to clarify the prognostic role of MCL-1, BCL-2 and BCL-2/ Bax ratio in B-CLL. Patients & method: Estimation of MCL-1, BCL-2 and Bax expressions by a flow cytometry in 45 B-CLL patients and the prognostic value of these markers were correlated with other well-known established prognostic markers and treatment response. Results: MCL-1 was expressed in 60% of cases while BCL-2 was expressed in 82.2% of cases. MCL-1 expression was significantly high in male gender, short lymphocyte doubling time (LDT), and high expression of CD 38 (p β2M, CD38 expression), low ZAP-70 expression, splenomegaly and higher Rai stage were significantly increased in patients with high expression of BCL-2 (p β2M, high C-D38 expression, low ZAP-70 expression, the poor cytogenetic and splenomegaly in patients with high expression of BCL-2/ Bax ratio (p In conclusion: MCL-1, BCL-2 expressions and BCL-2/Bax ratio could be useful potential predictive and prognostic markers in B-CLL.展开更多
目的:检测人白介素11(interleukin-11,IL-11)基因在弥漫性大B细胞淋巴瘤(diffuse large B-cell lymphoma,DLBCL)患者组织和血清标本中的表达,探讨IL-11表达与DLBCL患者预后的关系及其对化疗后患者血小板减少的影响。方法:收集2012年1月...目的:检测人白介素11(interleukin-11,IL-11)基因在弥漫性大B细胞淋巴瘤(diffuse large B-cell lymphoma,DLBCL)患者组织和血清标本中的表达,探讨IL-11表达与DLBCL患者预后的关系及其对化疗后患者血小板减少的影响。方法:收集2012年1月至2016年12月于河北省邯郸市第一医院血液科确诊的88例DLBCL患者和42例反应性淋巴增生(reactive lymphoid hyperplasia,RLH)患者组织和血液标本。用q PCR方法检测肿瘤组织和血液中IL-11的表达,应用单因素和多因素Cox回归分析IL-11表达与DLBCL患者临床病理特征和预后的关系以及影响患者预后的独立因素,相关性分析DLBCL患者IL-11表达和化疗后血小板减少的关系,Kaplan-Meier法分析IL-11表达与DLBCL患者总生存(OS)时间、无进展生存(PFS)时间的关系。结果:与对照组RLH患者比较,IL-11在DLBCL患者组织和血液中表达显著升高(组织:7.002±0.357 vs 1.507±0.139;血液:6.700±0.337 vs1.446±0.126,均P<0.01)。IL-11表达与DLBCL患者的肿瘤大小、临床分期、B细胞症状、化疗敏感性及IPI指数相关(均P<0.01),IL-11高表达患者OS和PFS较IL-11低表达患者明显缩短(均P<0.01)。单因素及多因素Cox回归分析显示,IL-11表达、化疗敏感性和IPI指数是影响DLBCL患者预后的独立因素。化疗后血小板减少患者血清IL-11基因表达与血小板计数呈负相关(r=-0.732,P<0.01)。结论:IL-11在DLBCL患者组织和血液中高表达,IL-11高表达DLBCL患者OS和PFS明显缩短,化疗后血小板减少严重。IL-11有望成为DLBCL患者独立的预后评判生物学标志物。展开更多
