[A long-term survivor of a rectal carcinoid treated by use of repeat TACE for multiple intrahepatic recurrences after liver resection and MCT].

ABSTRACT

A woman between 50 and 60 years of age was diagnosed with a rectal carcinoid tumor and synchronal multiple liver metastases. We performed a transanal local resection of the rectal tumor, which was 10mm in diameter. During surgery, ultrasonography revealed 8 hypoechoic masses in the liver, and we performed a partial hepatectomy (S5/6, S8) and administered microwave coagulation therapy. Thirty-seven months after surgery, abdominal computed tomography revealed multiple low-density tumors in the bilateral lobe of the liver. We diagnosed these tumors as a recurrence of the liver metastases of the rectal carcinoid and performed trans-arterial chemo-embolization (TACE). After repeated TACE treatments, the liver metastases were controlled favorably. The patient is alive more than 50 months after diagnosis of the recurrent liver metastases. TACE appears to be effective for treating non-resectable multiple liver metastases of rectal carcinoids.
