摘　　要：目的探讨MSCT在非小细胞肺癌(NSCLC)TNM分期诊断中的临床价值.方法选取100例经病理证实的NSCLC患者,采用2017年国际肺癌研究协会发布的肺癌TNM分期第8版标准,将MSCT诊断的TNM分期结果与病理分期结果进行对比研究,分析MSCT诊断的TNM分期结果与病理诊断的TNM分期的一致性.结果100例NSCLC患者肿块的病理结果:肿块大小18.3~59.6 mm,平均(31.8±12.6)mm,淋巴结短径6.3~18.4 mm,平均(12.8±2.3)mm;病理TNM分期:T1N0M011例,T1N1M020例,T1N2M011例,T2N1M024例,T2N2M015例,T2N3M14例,T3N3M115例,即ⅠA期11例,ⅡB期44例,ⅢA期26例,ⅣB期19例.MSCT结果:肿块大小16.5~63.1 mm,平均(33.9±13.7)mm,淋巴结短径10.1~19.3 mm,平均(14.5±2.9)mm;CT-TNM分期:T1N0M015例,T1N1M020例,T1N2M09例,T2N1M030例,T2N2M07例,T2N3M14例,T3N3M115例,即ⅠA期15例,ⅡB期50例,ⅢA期16例,ⅣB期19例.CT-TNM分期与病理TNM分期的一致性好,总的符合率为90.0%,其中T分期的符合率为92.0%,N分期的符合率为80.0%.结论MSCT对NSCLC的TNM分期的准确性较高,其与病理TNM分期的一致性较好,对于患者病情的判断、治疗计划制定及放疗靶区勾画等有极为重要的临床意义.Objective To explore the clinical value of MSCT in the TNM staging diagnosis of non-small cell lung cancer(NSCLC).Methods 100 cases of NSCLC confirmed by pathology were selected.The 8th edition of TNM staging for lung cancer issued by the International Lung Cancer Research Association in 2017 was adopted.The TNM staging results diagnosed by MSCT were compared with those by pathology,and the consistency between the two were analyzed.Results Pathological results of masses in 100 patients with NSCLC:the size of the mass was 18.3-59.6 mm,the average was(31.8±12.6)mm.The short diameter of lymph node was 6.3-18.4 mm,the average was(12.8±2.3)mm.The pathological TNM staging:11 cases of T1N0M0,20 cases of T1N1M0,11 cases of T1N2M0,24 cases of T2N1M0,15 cases of T2N2M0,4 cases of T2N3M1 and 15 cases of T3N3M1.Namely,there were stage ⅠA in 11 cases,ⅡB in 44 cases,ⅢA in 26 cases andⅣB in 19 cases.MSCT results:the size of the mass was 16.5-63.1 mm,the average was(33.9±13.7)mm;the short diameter of lymph node was 10.1-19.3 mm,the average was(14.5±2.9)mm.The CT-TNM staging:15 cases of T1N0M0,20 cases of T1N1M0,9 cases of T1N2M0,30 cases of T2N1M0,7 cases of T2N2M0,4 cases of T2N3M1 and 15 cases of T3N3M1.Namely,there were stage ⅠA in 15 cases,ⅡB in 50 cases,ⅢA in 16 cases andⅣB in 19 cases.The CT-TNM staging was greatly consistent with pathological TNM staging.The overall coincidence rate was 90.0%,and that of the T staging was 92.0%,the N staging was 80.0%.Conclusion MSCT has high accuracy for TNM staging of NSCLC,and it has good consistency with pathological TNM staging.It is extremely important for patients'judgment,treatment planning and radiotherapy target area delineation.
