EGFR基因突变与肺腺癌主要病理分型及标本类型的关系
背景与目的随着基因突变技术及靶向药物治疗如火如荼的开展,对肺腺癌的精准治疗越来越受到关注,目前肺腺癌中研究最多的是表皮生长因子受体(epidermal growth factor receptor,EGFR)。对于EGFR突变和病理分型的关系在不同标本中是否一致,目前不甚明了。本研究比较肺腺癌活检标本和手术切除标本中EGFR基因突变与病理分型的关系是否一致,探讨EGFR基因突变与肺腺癌病理分型的关系以及标本类型对EGFR基因检测的影响。方法收集肺腺癌手术切除标本(楔形肺切除、肺叶切除标本)163例,肺腺癌活检[粘膜活检、肺穿刺、支气管内超声引导针吸活检术(endobronchial ultra...

Summary: | 背景与目的随着基因突变技术及靶向药物治疗如火如荼的开展,对肺腺癌的精准治疗越来越受到关注,目前肺腺癌中研究最多的是表皮生长因子受体(epidermal growth factor receptor,EGFR)。对于EGFR突变和病理分型的关系在不同标本中是否一致,目前不甚明了。本研究比较肺腺癌活检标本和手术切除标本中EGFR基因突变与病理分型的关系是否一致,探讨EGFR基因突变与肺腺癌病理分型的关系以及标本类型对EGFR基因检测的影响。方法收集肺腺癌手术切除标本(楔形肺切除、肺叶切除标本)163例,肺腺癌活检[粘膜活检、肺穿刺、支气管内超声引导针吸活检术(endobronchial ultrasound-guided transbronchial needle aspiration,EBUSTBNA)标本]173例,按照2015年世界卫生组织(World Health Organization,WHO)肺腺癌分型标准对其主要组织学分型确认(贴壁型、腺泡型、乳头型、微乳头型、实体型),行EGFR基因检测[基因测序法及突变扩增阻滞系统(amplification refractory mutation system,ARMS)]。分别对活检标本和手术切除标本进行统计。结果163例的肺腺癌手术切除标本中,102例EGFR基因突变,突变率为62.58%,173例的活检标本中,114例EGFR基因突变,突变率为65.9%。两组标本中EGFR突变率没有统计学差异(P〉0.05)。两组标本中女性的EGFR突变率均明显高于男性(P〈0.05)。手术切除标本中60岁以上患者的EGFR突变率明显低于60岁以下(P〈0.05),而活检标本中EGFR突变与年龄无关(P〉0.05)。在EGFR突变的两组标本中病理分型构成比不同(χ2=8.040,P〈0.05)。手术切除标本肺腺癌中EGFR突变的102例中,腺泡型占54.9%(56例),贴壁型占23.53%(24例),乳头型占17.65%(18例),实体型占3.9%(4例),其中腺泡型所占比例最高,其次是贴壁型和乳头型,实体型则比例最少。19、21外显子单独突变最多,21外显子突变在贴壁型较其他两型高(P〈0.05),19外显子突变在乳头型较贴壁型高(P〈0.05)。腺泡型和乳头型比较,19、21外显子突变无统计学意义。活检标本肺腺癌中EGFR突变的114例中腺泡型占48.25%(55例) |

It is unclear whether the result of EGFR mutation and pathology type is consistent with different specimens. In our study, by comparing the relationship between EGFR mutations and pathological classification of lung adenocarcinoma in surgical resection of specimen and biopsy specimen, to discuss the relationship between EGFR mutations and pathological classification of and the influence of specimen type on EGFR gene detection. Methods A total of 163 cases of surgical resection of sample of lung adenocarcinoma(pulmonary resection and pulmonary lobectomy) and 173 cases of biopsy specimen [mucosa biopsy, needl |
