Parameter	ESD, n = 98	Surgery, n = 220	d-CRT, n = 16
Follow up time	40.0 (35.0-48.0)	43.0 (34.0-53.75)	32.5 (28.3-40.0)
Total cost	25	100	130
Death toll	1 (1.0)	19 (8.6)	3 (18.8)
Recurrence	4 (4.0)	3 8(17.3)	4 (25.0)
Salvage measures after recurrence or metastasis	Surgery (n = 3)	Surgery (n = 5)	Neoadjuvant chemo-radiotherapy (n = 1)
	No treatment (n = 1)	Neoadjuvant radiotherapy (n = 4)
		Neoadjuvant chemotherapy (n = 8)
