Abstract:
Objective To explore the value of high-resolution CT combined with serum epidermal growth factor receptor(EGFR)and metastasis associated gene l(MTA1)in distinguishing multiple primary lung adenocarcinoma and lung adenocarcinoma with intrapulmonary metastasis.Methods From October 2020 to October 2022,56 patients with multiple primary lung adenocarcinoma accepted by our hospital were regarded as the multiple primary lung adenocarcinoma group,47 patients with lung adenocarcinoma and intrapulmonary metastasis admitted to our hospital were as the lung adenocarcinoma and intrapulmonary metastasis group,and 50 healthy individuals were as the control group.The basic data of multiple primary lung adenocarcinoma patients and lung adenocarcinoma patients with intrapulmonary metastasis were collected,organized,and compared;the serum EGFR and MTA1 levels were compared between the control group,multiple primary lung adenocarcinoma patients,and lung adenocarcinoma patients with intrapulmonary metastasis;the imaging matching types of multiple primary lung adenocarcinoma patients and lung adenocarcinoma patients with intrapulmonary metastasis were compared;the imaging features of the main and accompanying lesions in the two groups were compared;receiver operating characteristic(ROC)curve was applied to analyze the value of high-resolution CT combined with serum EGFR and MTA1 in distinguishing multiple primary lung adenocarcinoma and lung adenocarcinoma with intrapulmonary metastasis.Results There was no significant difference in age between patients with multiple primary lung adenocarcinoma and those with lung adenocarcinoma with intrapulmonary metastasis(P＞0.05),however,the proportion of males and those with a history of smoking in lung adenocarcinoma and intrapulmonary metastasis group was obviously higher than that in multiple primary lung adenocarcinoma group(P＜0.05);the levels of serum EGFR and MTA1 in patients with lung adenocarcinoma and intrapulmonary metastasis were obviously higher than those in the multiple primary lung adenocarcinoma group and control group(P＜0.05);in the imaging matching types,there were significant differences between multiple primary lung adenocarcinoma group and lung adenocarcinoma with intrapulmonary metastasis group in pure ground glass nodules,mixed ground glass nodules,solid nodules,pure ground glass nodules+mixed ground glass nodules,pure ground glass nodules+solid nodules,and mixed ground glass nodules+solid nodules(P＜0.05);there was a significant difference in the presence or absence of ground glass components and vacuoles in the main lesion between the group of multiple primary lung adenocarcinoma and the group of lung adenocarcinoma with intrapulmonary metastasis(P＜0.05),the shape,clear boundary,presence or absence of ground glass components,lobulation,and vacuoles in the accompanying lesions of patients in two groups had a significant impact on the accompanying lesions(P＜0.05);ROC curve showed that the area under the curve(AUC)of high-resolution CT,serum EGFR,and MTA1 for distinguishing multiple primary lung adenocarcinoma and lung adenocarcinoma with intrapulmonary metastasis was 0.819,0.778,0.826,and 0.908,respectively,the combined identification value of the three was superior to individual identification(Zthree combination-high-resolution Ct=3.026,P=0.003,Zthree combination-EGFR=3.057,P=0.002,Zthree combination-MTAI=2.361,P=0.018).Conclusion Serum EGFR and MTA1 levels,and high-resolution CT have certain clinical reference value for distinguishing multiple primary lung adenocarcinoma and lung adenocarcinoma with intrapulmonary metastasis,and the combination of the three has a good differentiation effect.
