Aims To explore the long-term survival in lung cancer patients with persistent mediastinal lymph nodal disease after neoadjuvant followed by surgical resection and to analyse prognostic factors in this specific subset of patients Background Surgery in non-small-cell lung cancer (NSCLC) patients with N2-disease after neoadjuvant therapy (NAD) has been debated and has been even more questioned with the advent of immunotherapy. Objective Describe long-term results of a multimodal approach in locally-advanced NSCLC patients with persistence of N2-disease and identify prognostic factors to target the strategy of care. Methods We retrospectively reviewed data of 121 consecutive Stage IIIA-N2 NSCLC patients who underwent NAD (chemoradiotherapy or chemotherapy) from 01/00 to 12/19, focusing our analysis on 37 patients with persistent N2s status after surgery. Kaplan-Meier and Cox regression analysis explored the associations between mortality and potential risk factors. Results The 5-year survival was 29.8%. Cox regression analysis suggested that young age (HR=0.98, C.I.95%: 0.97- 1.00; p=0.062), male sex (HR=3.8,C.I.95%:1.06-13.73;p=0.04), and adjuvant therapy (HR=6.81,C.I.95%:0.96-53.94;p=0.06) influenced long-term outcomes in these patients. Conclusion We herein observed suboptimal long-term results in this NSCLC patient subset, and, considering emerging results adopting immunotherapy following chemoradiotherapy, surgery should be carefully considered in very selected cases (young and clinically fit patients) and combined with adjuvant therapy after surgery.
