Table 3 Cox multivariate regression analysis for loco-regional recurrence-free survival (LRFS)^a

Prognostic variable		Hazard ratio	95% CI^b	Pvalue
EGFR extent	<25% ≥25%	1 7.18	1.12 to 46	0.037
Resection	R0 R1	1 6.92	1.18 to 40.42	0.032
Preoperative RT	60 Gy 44 Gy	1 5.78	1.04 to 32.06	0.045

^aResults were adjusted on tumor stage, gender, type of surgery, surgical margin, age, preoperative radio-chemotherapy, EGFR intensity, delay from radiotherapy to surgery, and uT
