不同密度肺结节及病理资料分析

Analysis of different density pulmonary nodules and pathological data

目的:分析在肺结节中不同密度患者的临床及病理资料。方法:2018年7月-2020年7月收治不同密度肺结节患者1025例,按照不同密度分为三组,A组实质性结节232例;B组混合磨玻璃结节325例;C组纯磨玻璃结节468例。比较三组患者临床及病理资料。结果:三组体重下降比例、咳痰比例及年龄比较,差异有统计学意义(P<0.05)。三组结节最大径、毛刺征、分叶征及胸膜凹陷征占比比较,B组>A组>C组,差异有统计学意义(P<0.05)。三组肺腺癌、鳞状细胞癌及腺鳞癌比例比较,B组最多,差异有统计学意义(P<0.05)。结论:不同密度肺结节患者CT表现、临床症状、病理结果等存在较大差异,其中混合磨玻璃结节恶性程度最高。

Objective:To analyze the clinical and pathological data of patients with different densities in lung nodules.Methods:From July 2018 to July 2020,1025 patients with pulmonary nodules of different densities were selected,they were divided into the three groups according to different densities.232 cases of substantive nodules in the group A.325 cases of mixed ground glass nodules in the group B.468 cases of pure ground glass nodules in the group C.We compared the clinical and pathological data of the three groups of patients.Results:There were significant differences in the proportion of weight loss,expectoration and age among the three groups(P<0.05).The proportions of maximum nodule diameter,hairpin sign,lobulation sign and pleural depression sign in the three groups were the group B>the group A>the group C,the difference was statistically significant(P<0.05).Comparison of the proportions of lung adenocarcinoma,squamous cell carcinoma and adenosquamous carcinoma in the three groups,the group B was the most,the difference was statistically significant(P<0.05).Conclusion:There are great differences in CT manifestations,clinical symptoms and pathological results in patients with different densities of pulmonary nodules,among which the malignant degree of mixed ground glass nodules is the highest.
