Analysis of the clinical factors associated with anal function after intersphincteric resection for very low rectal cancer

Table 3 Characteristics of six patients with local recurrence after intersphincteric resection (ISR)

Patient	TNM	T stage	Histological type	Surgical procedure	Distal resection margin, mm	Circumferential resection margin, mm	Localization	Distant metastases	Treatment	Outcome
1	IIA	T3	G2	tISR + pESR	7	2	Pelvic wall	NS	CRT	45 months, O
2	IIIB	T3	G2	sISR + pESR	25	2	Pelvic wall	NS	CRT	70 months, S
3	IIIB	T3	G2	pISR	12	5	Pelvic wall	Bone, lung	Cx	31 months, P
4	IIA	T3	G2	pISR	10	0.5	Lateral node	Adrenal gland	Cx	36 months, P
5	I	T2	G1	pISR	3	6	Anastomosis	NS	APR	22 months, S
6	IIB	T3	G1	pISR	3	0.5	Lateral node	NS	CRT	17 months, S

Distal resection margins and circumferential resection margins were measured on the histological slides.
APR = abdominoperineal resection; CRT = chemoradiotherapy; Cx = chemotherapy; ESR = external intersphincteric resection; ISR = intersphincteric resection; NS = not stated; O = other origin of death; P = primary death; S = survived.
