Prognostic implications of FGFR1 and MYC status in esophageal squamous cell carcinoma

Table 3 Correlation of fibroblast growth factor receptor 1 and MYC amplification status between the tumors of the primary and the metastatic lymph nodes, n (%)

		Metastatic lymph nodes		Total	P value
		No amplification	Amplification
FGFR1 Primary tumor	No amplification	42 (91.3)	3 (6.7)	45 (100)	< 0.001
	Amplification	4 (36.4)	7 (63.6)	11 (100)
	Total	46 (82.1)	10 (17.9)	56 (100)
MYC Primary tumor	No amplification	17 (63.0)	10 (37.0)	27 (100)	1.000
	Amplification	12 (60.0)	8 (40.0)	20 (100)
	Total	29 (61.7)	18 (38.3)	47 (100)
