[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.
