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

Table 6 The 3-, 5-, and 10-yr cancer-specific survival rates for node-positive patients based on lymph node ratio cutoff points

LNR	3-yr, %	5-yr, %	10-yr, %	Follow-up, mo	Median follow-up, mo	Median survival, mo
ALL	67.3	58.4	48.9	0-347	33	-
0-0.16	88.5	80.8	68.9	0-347	45	-
0.17-0.48	59.7	46.2	37.4	1-345	32	46
0.49-1	24.7	17.7	14.2	0-203	16	18

Median survival is unavailable when there were not half patients dead at the cutoff date. LNR: Lymph node ratio (the ratio of positive lymph nodes to the total lymph nodes examined).
