[Experience and evaluation of extended resection and lymph nodes dissection in stage T3-4N2M0 lung cancer]
Objective:
To report our experience of surgical treatment for stage T3-4N2M0 lung cancer.
Methods:
One hundred thirty one patients with lung cancer in stage T3-4N2M0 were surgically treated by extended tumor resection, lymph nodes dissection and resection of ipsilateral mediastinal pleura and fatty tissue.
Results:
The 3-year survival rate of patients in stage T3N2M0 with squamous-cell carcinoma and adenocarcinoma was 34% and 18%, respectively. That for stage T4N2M0 patients was only 13% and 5%, respectively. The survival rate was not improved in patients who received combination treatment in addition to surgery.
Conclusion:
The indication of extended resection with lymph node dissection in the treatment of T3-4N2M0 lung cancer is limited.
