                cytic leukemia,CLL)中的应用及与患者临床指标和特征的相关性,并分析其判断患者预后的价值。方法:收集2013年6月—
                2020年10月初诊于南通大学附属医院CLL患者74例,男43例,女31例。收集患者相关的临床特征、实验室检查、骨髓涂片、
                免疫分型及FISH结果等资料。分析FISH检测的分子遗传学异常与患者的性别、年龄、临床Binet分期、Rai分期及相关实验室

                genase,LDH)水平]的相关性。结果:①CLL患者FISH检测至少具有1种分子遗传学异常者为56例,发生率为75.68%。②各

                布差异具有统计学意义(χ =4.696,P=0.041);C 期的生存时间明显短于 A 和 B 期(χ =14.242,P=0.001)。就改良的 Rai 分期而
                                                                                2

                言,ATM基因缺失仅在高危组检出,且此种分布差异具有统计学意义(χ =5.40,P < 0.001);低中危组的生存时间明显优于高危
                                                                      2

                组(χ =12.393,P < 0.001);单纯 del(13q)核型异常的 CLL 患者生存时间明显长于伴有其他核型异常及复杂核型的患者(χ =
                8.138,P=0.017)。结论:CLL为惰性疾病,但其疾病进展和临床预后具有高度异质性。FISH检测结果联合疾病临床分期可更
                好地预测患者预后。

               [Abstract] Objective:This study aims to investigate the correlation between cytogenetic detected by fluorescence in situ
                hybridization(FISH)and the patients’clinical features in chronic lymphocytic leukemia(CLL),to analyze the prognostic value.
                Methods:Total 74 cases of chronic lymphocytic leukemia patients were collected in Nantong University Affiliated Hospital from June
                2013 to October 2020,with 74 cases of newly diagnosed patients,43 males and 31 females. The clinical characteristics of patients,
                laboratory tests,bone marrow smear results,immunological typing results,FISH results and other information were collected. The
                correlation between cytogenetic abnormalities and gender,age,the clinical Binet staging,Rai staging and the related laboratory
                examinations [including peripheral blood lymphocyte absolute count,hemoglobin,platelets,lactate dehydrogenase(LDH),β2 ⁃
                microglobulin(β2⁃MG)]were analyzed. Results:①Cytogenetic abnormalities were found in 56 of 74 CLL patients(75.68%). ②There
                was no significant relationship among the cytogenetic abnormalities and the sex,age,peripheral blood lymphocytes,hemoglobin,
                platelet,β2⁃MG,LDH expression level(P > 0.05). ③In the case of Binet stage,chromosome 12(+12)was only detected in stage B
