Table 3

Prognostic factors according to clinically, histopathologically, and immunohistochemically studied parameters (EN: endoluminal necrosis; ITE: intravascular tumoral emboli).

Prognosis	Stages	Tumor grade	Tumor size (cm)	Tumor localization	p53	p21	CD 68	Ki 67	Metastasis	EN, ITE
Better	IA; IB	G1	1-1.5	Head of pancreas	—	+	Present in peritumoral tissue	<5%	No	No
Poor			>5	Body or/and tail	+	—	Absent in peritumoral tissue	>30-35%	Yes	Yes
		G2, G3	>5-6	Body or/and tail or head
