Methods We investigated the association between EGFR gene mutations and clinical features, including serum tumor marker levels, in 97 advanced lung adenocarcinomas patients who did not undergo the treatment of EGlaR tyrosine kinase inhibitors. EGFR gene mutation was detected by real-time PCR at exons 18, 19, 20, and 21. Serum tumor marker concentrations were analyzed by chemiluminescence assay kit at the same time. Results EGFR gene mutations were detected in 42 （43%） advanced lung adenocarcinoma patients. Gender （P=0.003）, smoking status （P=0.001）, and abnormal serum status of carcinoembryonic antigen （CEA, P=0.028） were significantly associated with EGFR gene mutation incidence. Multivariate analysis showed the abnormal CEA level in serum was independently associated with the incidence of EGFR gene mutation （P=0.046） with an odds ratio of 2.613 （95% Ch 1.018-6.710）. However, receiver operating characteristic （ROC） curve analysis revealed CEA was not an ideal predictive marker for EGFR gene mutation status in advanced lung adenocarcinoma （the area under the ROC curve was 0.608, P=0.069）. Conclusions EGFR gene mutation status is significantly associated with serum CEA status in advanced lung adenocarcinmoas. However, serum CEA is not an ideal predictor for EGFR mutation.展开更多
目的比较伴或不伴基因突变的原发性肺腺癌在体积倍增时间(volume doubling time,VDT)和质量倍增时间(mass doubling time,MDT)间的差异。方法选取2019年1月—2020年12月在同济大学附属上海市肺科医院进行手术治疗且术前至少进行2次胸部...目的比较伴或不伴基因突变的原发性肺腺癌在体积倍增时间(volume doubling time,VDT)和质量倍增时间(mass doubling time,MDT)间的差异。方法选取2019年1月—2020年12月在同济大学附属上海市肺科医院进行手术治疗且术前至少进行2次胸部非增强CT扫描的患者为研究对象。根据放射科医师手工分割的三维掩模计算VDT和MDT。采用Bland-Altman方法进行观察者内变异性评估。采用Mann-Whitney U检验比较驱动基因有无突变肿瘤的VDT和MDT差异。采用Kruskal-Wallis检验比较不同EGFR突变位点VDT和MDT的差异。结果共计279例患者(男性99例,女性280例),平均年龄(62.15±8.90)岁,共287个结节。根据驱动基因状态分为突变组72例,野生组215例,基因突变发生率为74.9%(215/287)。突变组和野生组MDT在驱动基因状态上的差异有统计学意义(537 d vs 824 d,P=0.004),VDT的差异无统计学意义(767 d vs 593 d)。EGFR阳性腺癌的MDT比EGFR阴性腺癌长,但VDT差异并不显著(VDT,758 d vs 593 d,P=0.382;MDT,824 d vs 537 d,P=0.004)。在生长结节中,驱动基因阳性腺癌的VDT和MDT均比野生型腺癌长(VDT,759 d vs 592 d,P=0.048;MDT,749 d vs 499 d,P<0.001;VDT,768 d vs 593 d,P=0.081,MDT,737 d vs 518 d,P=0.001)。结论在原发性浸润性肺腺癌中,驱动基因阳性(尤其是EGFR阳性)的肿瘤倍增时间更长,且在生长中的结节中更为显著。展开更多
