Prognostic impact of number of examined lymph nodes on survival of patients with appendiceal neuroendocrine tumors

Table 5 The 3-, 5-, and 10-yr cancer-specific survival rates by lymph node status and cutoff points of examined lymph nodes

Patients	ELNs	3-yr, %	5-yr, %	10-yr, %	Follow-up, mo	Median follow-up, mo	Median survival, mo
All	≤ 10	83.2	76.1	67.9	0-306	36	-
	≥ 11	90.3	85.5	79.1	0-347	38	-
Node-negative	≤ 6	94.9	86.5	79.3	0-306	28	-
	≥ 7	98.1	95.4	90.1	0-326	43	-
Node-positive	≤ 17	60.7	50.0	40.6	0-345	31	60
	≥ 18	78.4	71.5	61.4	0-347	35	-

Median survival is unavailable when there were not half patients dead at the cutoff date. ELNs: Examined lymph nodes.
