[Debulking operation for non-small cell lung cancer].
OBJECTIVE
To assess effectiveness and influencing factors of debulking operation for non-small cell lung cancer.


METHODS
The cumulative survival and its influencing factors were analyzed and compared by the Kaplan-Meier and Cox model of SPSS for Windows in 244 patients received debulking operation and 364 received thoracotomy.


RESULTS
The 1, 3, 5-year cumulative survival of patients treated with debulking operation was 56.9%, 20.6%, 17.5% respectively while that received thoracotomy was 41.1%, 7.8%, 5.3%, respectively (debulking vs thoracotomy, Breslow = 27.55, P < 0.0001). Multivariate analysis showed that the debulking operation or thoracotomy (B = -0.4600, P < 0.0001) and postoperative adjuvant therapies (B = -0.1059, P = 0.0216) were the most important influencing factors on the cumulative survival.


CONCLUSIONS
Tumor debulking operation is an important treatment for stage III, IV non-small cell lung cancer. With postoperative adjuvant chemoradiotherapy better survival can be achieved.
