Comparison of median biomarker levels for patients with complete and incomplete responses to CRT

Biomarker	Complete response	Incomplete response	p -value
Pre-CRT neutrophils	5.09 × 109/l	4.87 × 109/l	0.585
Pre-CRT lymphocytes	1.91 × 109/l	1.57 × 109/l	0.290
Pre-CRT NLR	3.00	3.32	0.774
Post-CRT neutrophils	3.54 × 109/l	3.98 × 109/l	0.423
Post-CRT lymphocytes	0.83 × 109/l	0.68 × 109/l	0.408
Post-CRT NLR	4.37	4.81	0.542
Pre-CRT monocytes	0.58 × 109/l	0.61 × 109/l	0.713
Pre-CRT haemoglobin	13.8g/dl	13.2g/dl	0.064
Pre-CRT CRP	9.5mg/l	7.5mg/l	0.970
Pre-CRT CEA	3.1ng/ml	4.3ng/ml	0.401

CEA = carcinoembryonic antigen; CRP = C-reactive protein; CRT = chemoradiotherapy; NLR = neutrophil-to-lymphocyte ratio
