During a 12-year period

44 patients were surgically treated for stage- Ⅲ peripheral squamous cell car-cinoma of the right upper lobe. 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.
