Abstract:

Objective

To investigate the preliminary efficacy and safety of drug-eluting beads transarterial chemoembolization (DEB-TACE) for the treatment of liver metastasis of neuroendocrine tumors (NEN-LM).

Methods

The clinical data of 27 patients with NEN-LM treated in Interventional Department from March 2019 to January 2020 were analyzed retrospectively, including 20 pancreas of primary site, 3 duodenum, and 4 rectum. All patients were diagnosed by pathology. Twelve patients underwent treatment of DEB-TACE (DEB-TACE group) and 15 patients were treated with Lipiodol (cTACE group). Response of hepatic lesions were assessed according to mRECIST. Objective response rates (ORR) and safety were compared of the two groups. Follow-up period ranged from 9 to 15 months.

Results

The ORRs of 1, 3, 6 and 12 months were 91.7%, 83.3%, 58.3% and 54.5% respectively in DEB-TACE group, but 86.7%, 66.7%, 40.0% and 14.3% respectively in cTACE group. The ORR of 12 months in DEB-TACE group was significantly higher than that in cTACE group (P = 0.043). The main complication of the two groups was post-embolization syndrome, and there was no significantly difference (P > 0.05). No serious complications occurred.

Conclusions

Compared to cTACE, DEB-TACE can effectively reduce tumor burden in patients with NEN-LM, which is safe and well-tolerated.
