Abstract:
Objective：To investigate the clinicopathological features of surgical resection of non-small cell lung cancer(NSCLC) with diameter ≤2 cm.Methods：From 2010 to 2014，a total of one hundred and thirty-eight patients with non-small cell lung cancer of ≤2 cm or less in greatest diameter were operated on in our institution.The effect of surgical approach，lymph node involvement and histology on postoperative survival were retrospectively analyzed with clinicopathological data and postoperative follow-up.Results：The overall 5-year survival rate was 71.7%.Lymph node metastasis was found in 24 of 138(17.4%) patients.The 5-year survival rate for patients without lymph node metastasis was 82.7%，whereas it was 75.0% and 48.1% for those with pN1 and pN2 diseases(P＜0.05).Patients receiving lobectomy had a significantly better survival rate than patients receiving limited resection(P＜0.05).The 5-year survival rates for patients with stageⅠ，stage Ⅱ and stage Ⅲ were 89.8%，77.8% and 43.1%，respectively(P＜0.05).Conclusion：The survival of patients with non-small cell lung cancer with diameter ≤2 cm is closely related to the nodal involvement，stage of disease and surgical approaches.The indications for avoiding systematic lymph node dissection for operable NSCLC should not be based on the size of the tumor.
