The LCSS curves in IIIA/N2 NSCLC subgroups with different surgery and radiotherapy combination. Log Rank p < 0.001 in each subgroup. p-value of the lung cancer-specific survival of patients treated by preoperative radiotherapy compared to patients who underwent PORT was 0.5293. Each p value < 0.05 in the pairwise comparison of other subgroups. The number of patients at risk in different time periods was in Supplementary Table 1. Abbreviations: NSCLC, non-small cell lung cancer; IIIA/N2, stage IIIA pathologic N2; LCSS, Lung cancer-specific survival; PORT, postoperative radiotherapy
