[Retracted] Risk Factors and Prognostic Analysis of Gastrointestinal Stromal Tumor Recurrence-Metastasis

Table 1

Risk stratification of gastrointestinal stromal tumors.

Risk stratification	Tumor diameter(cm)	Mitotic count (per 50 HPFs)	Primary location of tumor	The number of cases
Very low	<2.0	≤5	Any location	152
Low	2.1-5.0	≤5	Any location	119
Intermediate	2.1-5.0	>5	Gastric	44
	<5.0	6-10	Any location
	5.1-10.0	≤5	Gastric
High	Any size	Any mitotic rate	Tumor rupture	107
	>10.0	Any mitotic rate	Any location
	Any size	>10	Any location
	>5.0	>5	Any location
	2.1-5.0	>5	Nongastric
	5.1-10.0	≤5	Nongastric
