Clinical and pathological characteristics of 5 GIST patients with lymph node metastasis

Case	Sex	Age	Primary site	Tumor size	Mitotic rate per 50HPF	MLN/TLN	Mutation	IM therapy	Outcome
1	M	60	S	8	23	2/4	c-kit exon9	Yes	Died of disease progression at 33 months after surgery
2	M	58	G	5	12	1/2	not available	No	DFS at 101 months after surgery
3	F	59	G	5.5	<5	4/4	c-kit exon11	Yes	DFS at 45 months after surgery
4	F	70	G	9	8	1/9	c-kit exon11	Yes	DFS at 25 months after surgery
5	M	31	D	18	<5	2/2	c-kit exon11	Yes	Survival with residual disease at 3 months after surgery

S = small intestine; G = stomach; D = duodenum MLN = metastatic lymph nodes; TLN = total examined lymph nodes; DFS = Disease-free survival.
