Postoperative radiotherapy in resected non-small cell lung cancer: The never-ending story

Table 2 Proposed predictive model for locoregional recurrence in stage IIIA N2 non-small cell lung cancer[41]

Risk model for LRR in stage pIIIA-N2 NSCLC
Factor	Category	Score
EGFR status	Wild- type	4
LMR	LMR < 4.69	2
Type of surgery	Thoracotomy	3
LNR	LNR ≥ 38.9	4
Risk group	Score	3-yr LRFS
Low risk	0-2	71.4%
Medium risk	3-5	57.3%
High risk	6-13	13.6%

LRFS: Locoregional recurrence-free survival; LRR: Locoregional recurrence; NSCLC: Non-small cell lung cancer; LNR: Lymph node ratio; LMR: Lymphocyte-to-monocyte ratio.
