Pfetin as a Risk Factor of Recurrence in Gastrointestinal Stromal Tumors

Table 1

Clinicopathological features of the 45 gastrointestinal stromal tumors (GIST) cases.

		Cases	Recurrence	(%)	𝑃 value
Sex	Male	24	3	12.5	0.613
	Female	21	4	19.0
Age	38~87 years old				0.771
	(mean 66.2)
Location	Stomach	37	5	14.0	0.635
	Intestine	6	2	25
	Duodenum	1	0	0
	Rectum	1	0	0
Tumor size	<5 cm	25	0	0	𝑃<0.001
	5~10 cm	10	4	40
	>10 cm	10	3	30
Mitosis	<5/50 HPF	32	2	6.3	𝑃=0.035
	>5/50 HPF	13	5	38.5
MIB-1 index	≧10%	6	1	16.7	0.963
	<10%	39	6	15.4

Tumor size and mitosis have significant correlations with recurrence. These factors are also Fletcher’s agents. These data lead Fletcher’s classification to be good collation to recurrences.
