【摘要】:目的:为丰富中国非小细胞肺癌患者ALK阳性数据,及为筛选非小细胞细胞肺癌患者的ALK阳性患者及个体化治疗提供依据。材料及方法:收集广西医科大学附属肿瘤医院从2014年12月至2016年6月行ALK Ventana免疫组织化学染色的且经组织病理学明确诊断为非小细胞肺癌的患者532例,回顾性分析ALK融合基因阳性患者的临床特征,数据采用SPSS17.0软件进行统计分析,ALK阳性和阴性病人临床特征组间比较采用卡方检验,校正采用连续校正X2检验及Fisher确切概率法。P0.05认为有统计学意义。结果:1、在532例非小细胞肺癌患者中,男性患者326例,女性患者206例;平均年龄为56.9岁,65岁患者410例,≥65岁患者122例;手术标本153例,淋巴结活检标本43例,穿刺活检小标本313例,细胞学23例;有吸烟史患者238例,无吸烟史294例。在532例非小细胞肺癌中,腺癌455例,鳞癌52例,腺鳞癌13例,其他类型12例;原发部位位于左肺有215例,右肺有301例,中央型肺癌有201例,周围型肺癌有315例;TNM分期为Ⅰ期的病例有55例,Ⅱ期有27例,Ⅲ期有113例,Ⅳ期有324例;EGFR突变有132例,无EGFR突变有179例,EGFR突变率为42.4%。2、在532例非小细胞肺癌病例中,经ALK Ventana免疫组织化学染色检测,ALK阳性的有46例,阳性率为8.6%。3、在46例ALK融合基因阳性的患者中,分析其临床特征构成比,多见于年龄65岁、女性、无吸烟史、原发部位为右肺或中央型、TNM分期为Ⅳ期的肺腺癌患者,且多不合并EGFR基因突变。4、在ALK阳性组与ALK阴性组的对比中,其临床病理特征在年龄、性别、吸烟史、病理类型、原发部位为中央型或周围型、是否合并EGFR突变方面,差别具有统计学意义(P0.05),在原发部位为左肺或右肺、TNM分期上,差别无统计学意义(P0.05)。结论:ALK融合基因多在女性、年龄65岁、无吸烟史、中央型、肺腺癌、不合并EGFR突变的患者中表达,其差异具有统计学意义。
[Abstract]:Objective: to enrich the ALK positive data of non-small cell lung cancer (NSCLC) patients in China and to provide evidence for screening ALK positive patients and individualized treatment for NSCLC patients. Materials and methods: a total of 532 patients with non-small cell lung cancer (NSCLC) diagnosed by histopathology from December 2014 to June 2016 in the affiliated Cancer Hospital of Guangxi Medical University were collected. The clinical features of patients with positive ALK fusion gene were analyzed retrospectively. The data were statistically analyzed by SPSS17.0 software in order to compare the clinical features of positive and negative patients with ALK by chi-square test. Continuous correction X 2 test and Fisher exact probability method. Results among 532 patients with non-small cell lung cancer, 326 were male, 206 were female, 410 were 56.9 years old or 65 years old, 122 were 鈮,
