Abstract:
1.0～(?)1.5 cm(14.81%)(P=0.10).There was no lymph node metastasis in tumors less than 1.0 cm in diameter. The 5-year survival rates for cases with or without lymph node involvement were 92.31% and 60.0%,respectively,the difference was significant(P=0.000).The 5-year survival rates of 12 patients showing ground-glass opacity(GGO)on chest CT was 91.67% without any lymph node involvement.Conclusions:There is mediastinal and hilar lymph node involvement even with tumor diameter less than 2 cm.The results of the present study suggested that routine lymph node dissection is necessary even for cases with tumor diameter less than 2 cm.However,if the tumor is within 1.0 cm in diameter with obvious GGO showing on chest CT,these are good candidates for partial resection without mediastinal lymph node dissection.
