The mean time from the discovery of the shadow in the right upper lobe tothe confirmation of the diagnosis was 2 months. All patients underwent the resection of the right upperlobe with the dissection of the right mediastinal lymph nodes, among them, 4 patients had sleeve lobectomy of the right upper lobe. P-TNM staging: 23 cases were in stage- Ⅲ a, 21 cases in stage- Ⅲ b. The fre-quency of the postoperative complications was 20- 4 % (9/44 cases). The 1-year survival rate of all patientswas 61 % (27/44 cases). None of stage - Ⅲ b patients lived longer than 3 years. The postoperative 3-and 5-year survival rates of stage- Ⅲ a cases were 65. 2 % (15/23cases) and 21. 7 % (5/23 cases) respectively. Inthis article, the patients clinical features, the causes of delayed-diagnosis, the operative and postoperativemanagement were discussed. We suggest that the stage- Ⅲ a patients should be given surgical treatment,whereas, for the patients of stage- Ⅲ b, palliative operation was given just for the purpose of reliving thesymptoms.展开更多
