Abstract:
Objective To explore the impact factors of pathological grade of nonfunctional pancreatic neuroendocrine tumor(PNET)based on conventional ultrasound and contrast-enhanced ultrasound(CEUS).Methods Totally 86 patients with single lesion of nonfunctional PNET were retrospectively enrolled and divided into G1 grade group(n=48),G2 grade group(n=25)and G3 grade group(n=13)based on pathological results.Clinical and ultrasonic data were compared among groups,and logistic regression analysis was used to screen impact factors of pathological grade of nonfunctional PNET.Results Significant differences of the morphology,boundary,surrounding organs/blood vessels invasion or not,degree of arterial phase enhancement,venous phase enhancement and total enhancement pattern of lesions were found among 3 groups(all P＜0.05).The morphology,boundary,degree of arterial phase enhancement and degree of venous phase enhancement of lesions were all independent impact factors of pathological grade of nonfunctional PNET(all P＜0.05).Conclusion Morphology,boundary,degree of arterial phase enhancement and venous phase enhancement of lesions were all impact factors of pathological grade of nonfunctional PNET.
