Preliminary study about the value of CT radiological features in predicting the pathological grade of neuroendocrine neoplasm liver metastases
To explore the feasibility and value of computed tomography (CT) radiological features in differentiating liver metastases of neuroendocrine neoplasms (NEN) with different pathological grades.
Methods
2
NEN patients with hepatic metastases treated at Fudan University Shanghai Cancer Center between July 2021 and April 2025 were retrospectively enrolled and analyzed. Among these cases
G1/G2 lesions were confirmed by surgical pathology
while G3 lesions were confirmed by either biopsy or surgical pathology. The quantitative and qualitative features of the tumors on enhanced CT were evaluated
the differences in CT radiological features between G1/2 and G3 lesions were analyzed
and multivariate analysis was used to identity CT features with predictive value for pathological grades.
Results
2
A total of 67 NEN patients with hepatic metastases (encompassing 118 hepatic metastatic lesions) were enrolled in this study. Among these lesions
72
(61.0%) were G1/G2
and 46 (39.0%) were G3. The CT values of G1/2 liver metastases in the early arterial phase
late arterial phase
and venous phase were significantly higher than those of G3 liver metastases (all
P
<
0.001). The areas under the curve (AUC) of CT values in the early arterial phase
late arterial phase
and venous phase for differentiating pathological grades were 0.713
0.714
and 0.681
respectively. Among qualitative features
there were significant differences in arterial blood supply
dynamic enhancement pattern
vesicle sign
and tumor margin between G1/2 and G3 grades (all
P
<
0.05). Multivariate logistic analysis showed that tumor blood supply
dynamic enhancement pattern
tumor margin
intra-tumoral necrosis were independent predictors for differentiating liver metastases of G1/2 and G3 NEN. Poor blood supply
slow-rising enhancement pattern
blurred tumor margin
and extensive intra-tumoral necrosis suggested G3 liver metastasis.
Conclusion
2
CT radiological features are valuable in non-invasive differentiation of G1/2 and G3 NEN liver metastases
and are expected to provide assistance for precise treatment of NEN liver metastases.
