目的 探讨对伴有卫星结节的非小细胞肺癌患者的诊断及治疗策略。方法 2 3例接受手术治疗的非小细胞肺癌患者的术前CT扫描提示有性质不明的卫星结节存在。其中 2 1例获得病理诊断 ,另外 2例未获病理诊断 ,分别随访 1 6～ 2 1个月。结果 共发现 2 5个卫星结节 ,其中 1 0个结节为转移癌 ,另 1 5个结节为良性病变。当卫星结节的直径≤ 5mm或原发癌分期为Ⅰ、Ⅱ期时 ,结节是良性病变的可能性较高 ,但差异不具有统计学意义。结论 非小细胞肺癌患者伴随的卫星结节可能是转移癌 ,也可能是良性病变 ,在不能鉴别其性质时不能认为是手术的禁忌症。VATS是鉴别卫星结节性质较好的手段。
Objective To investigate the diagnosis and treatment of non-small cell lung cancer patients with satellite nodules. METHODS: Preoperative CT scan of 3 of 3 NSCLC patients undergoing surgical treatment suggested the presence of satellite nodules of unknown nature. Among them, 21 cases were pathologically diagnosed, while the other 2 cases were not pathologically diagnosed, and were followed up for 1-6 6 months. Results A total of 25 satellite nodules were found, of which 10 were nodules, and the other 15 were benign lesions. When the diameter of satellite nodules ≤ 5mm or primary cancer stage Ⅰ, Ⅱ, nodules are more likely to be benign lesions, but the difference was not statistically significant. Conclusion The satellite nodules associated with non-small cell lung cancer may be metastatic or benign, and can not be considered as contraindications to surgery without identifying their nature. VATS is a better way to identify satellite nodules.
