CT在非小细胞肺癌TNM分期的临床应用价值

目的 探讨CT用于非小细胞肺癌TNM分期的临床价值。方法 选取杭州市西溪医院2018年4月至2021年4月收治的122例非小细胞肺癌患者为研究对象，均于入院1周内完成胸部CT平扫加增强扫描。探讨CT与病理诊断非小细胞肺癌患者TNM分期的一致程度。结果 CT诊断淋巴结短径高于病理诊断（P<0.05），差异有统计学意义。122例非小细胞肺癌患者经术前CT诊断TNM分期，并与术后病理TNM分期比较，总体符合率为85.2%。CT对TNM分期和病理TNM分期一致性良好。术前CT诊断T分期，并与术后病理T分期比较，总体符合率为89.3%。CT-T分期和病理T分期一致性良好。术前CT诊断N分期，并与术后病理N分期比较，总体符合率为89.3%。CT-N分期和病理N分期一致性较好。CT诊断出胸壁侵犯伴胸腔积液10例，肝多发转移8例，与病理结果一致。结论 CT诊断非小细胞肺癌的TNM分期与病理TNM一致性良好，对临床制订手术方案和治疗方法具有指导作用。

Clinical value of CT in diagnosing TNM staging of non-small cell lung cancer

Objective To investigate the clinical value of CT in TNM staging of non-small cell lung cancer. Methods Totally 122 patients with non-small cell lung cancer admitted to Hangzhou Xixi Hospital from April 2018 to April 2021 were selected as the study subjects. All patients completed the chest TC plain scan and enhanced scan within one week after admission. To explore the consistency of TNM staging in patients with non-small cell lung cancer diagnosed by CT and pathology. Results The short diameter of lymph nodes diagnosed by CT was higher than that by pathology, with a statistical significance (P<0.05). Totally 122 patients with non-small cell lung cancer were diagnosed TNM staging by preoperative CT, and compared with postoperative pathological TNM staging, the overall coincidence rate was 85.2%. CT staging of TNM is consistent with pathological TNM staging. The overall coincidence rate between preoperative CT diagnosis of T staging and postoperative pathological T staging was 89.3%. CT-T staging was consistent with pathological T staging. The overall coincidence rate between preoperative CT diagnosis of N stage and postoperative pathological N stage was 89.3%. CT-N staging was consistent with pathological N staging. CT showed 10 cases of chest wall invasion with pleural effusion and 8 cases of liver multiple metastasis, which was consistent with the pathological results. Conclusion The TNM staging of non small cell lung cancer diagnosed by CT is in good agreement with the pathological TNM staging, which can guide the clinical formulation of surgical plans and treatment methods.
