Peri-operative Treatments in NSCLC
In wild-type NSCLC • Peri-operative chemotherapy • Preoperative chemoradiation • Perioperative targeted treatments • Peri-operative immunotherapy • Postoperative mediastinal radiotherapy
In EGFR mutated NSCLC Postoperative radiotherapy

Postoperative Radiotherapy: the Updated Meta-analysis
• IPD meta-analysis • 11 trials / 2343 pts
• HR=1.18
• 18% relative increase in risk of death
• Absolute detriment: 5% at 2 yr (95% CI=2-9%)
• reducing survival from 58 to 53%.

Conclusions: Perioperative chemotherapy
• Neo- and adjuvant chemotherapy increase survival in resectable NSCLC: +5% at 5 years
• Adjuvant chemotherapy: – stage II-III, IB ≥4cm – Best evidence for cisplatin-vinorelbine – cisplatin≥300 mg/m2
• Preoperative radiotherapy does not add to preoperative chemotherapy in stage IIIA N2
• Postoperative radiotherapy for N2?

Conclusions: New Treatments
• No indication for targeted therapies in wild-type EGFR
• Interest of EGFR and ALK TKIs to be demonstrated in EGFRmut/ALK+ NSCLC
• Interest of immune checkpoint inhibitors to be demonstrated
