Evaluation of CT Prognostic Factors of Neuroendocrine Liver Metastasis Treated with Transcatheter Arterial Embolization

#1378

Introduction: TAE has been shown to be effective in the management of metastatic NET.

Aim(s): To screen CT prognostic factors of neuroendocrine liver metastasis treated with transcatheter arterial embolization.

Materials and methods: CT images of 22 patients with 32 neuroendocrine liver metastases (10 patients with two metastases) treated with transcatheter arterial embolization from July 2010 to January 2015 were retrospectively analyzed. CT features (location, number, boundary, long diameter, short diameter, hyper- or hypovascular, enhancement pattern, attenuation, absolute and relative enhancement of tumor) between the responder (CR and PR) and nonresponder (SD and PD) groups, the decrease of long diameter after embolization using RECIST and modified RECIST (mRECIST) criteria between the hyper- or hypovascular groups were compared by independent t test or Mann-Whitney test.
