MiR-210 expression reverses radioresistance of stem-like cells of oesophageal squamous cell carcinoma

Table 1 Clinical and pathological data and levels of miR-210 expression in the selected oesophageal squamous cell carcinoma patients

Clinical feature		n	MiR-210 expression level		Local recurrence time
			Low	High	Early	Late and not
Pathological grade	II	11	7	6	2	9
	III	26	23	1b	17	9b
T-stage	II	13	11	2	3	10a
	III	24	19	5	16	8
Lymph node infiltration	+	16	12	4	11	5
	-	21	18	3	8	13

^aP < 0.05,

^bP < 0.01, patients vs the patients with miR-210 expression. All of the patients were male, with a median age of 54 (range, 42-71) years. The level of miR-210 expression was determined using quantitative reverse transcription-polymerase chain reaction. The level of expression in the oesophageal squamous cell carcinoma tissue was compared with that in the same patient’s para-tumorous normal oesophageal tissue. The endpoint of the follow-up period was when a local recurrence arose or at least 35 mo, and 18 mo was chosen to distinguish early and non-early recurrences.
