P2.02-022 - For down Staged Clinical N3 M0 Non-Small Cell Lung Cancer Patients Chemo-Radiotherapy Followed by Surgery Can Improve Survival (ID 5830)
14:30 - 14:30 | Author(s): J. Zhang
- Abstract
Background:
Non-small cell lung cancer (NSCLC) patients with clinical (c-) N3 M0 are conventionally regarded as inoperable. However, the role of surgery for such patients clinically down staged after chemo-radiotherapy has not been ascertained. We retrospectively compared the outcome after chemo-radiotherapy plus surgery for down staged patients versus only conventional chemo-radiotherapy.
Methods:
Patients treated at our institute from 2000 to 2016 for primary NSCLC with c-N3M0 were identified. Amongst them, six patients received lung resection surgery after chemo-radiotherapy was given and clinical evidence of downstaging found. Fifty patients received only conventional chemo-radiotherapy during the same period. Survival was estimated using the Kaplan-Meier method.
Results:
All of the 6 patients receiving chemo-radiotherapy plus surgery, are recurrence-free survival. The survival time ranged from 5 to 91 months. The 5-year overall survival for the patients receiving surgery was 100% compared with 24% for the 50 patients who did not receive surgery (p= 0.04).
Conclusion:
Our results suggest that the combination of chemo-radiotherapy plus surgery may improve survival for preoperatively down staged c-N3M0 NSCLC patients. These results should be validated by large-scale, prospective, randomized trials.
