Adrenocortical carcinoma with multiple liver metastases controlled by bland transarterial embolization and surgery resulting in long-term survival

Adrenocortical carcinoma (ACC) is a rare malignant tumor with a poor prognosis. Local recurrence or distant metastases occur in more than 50% of cases. Patients with metastases have limited treatment options, and <15% have a 5-year survival time. Herein, we describe a 44-year-old woman with ACC and who underwent retroperitoneal tumor resection. Multiple liver and lung metastases were found 1-year postresection. Mitotane therapy started as systemic treatment. Lung metastases were controlled but liver metastases were progressive. The liver metastases were treated by performing 2 resections and 6 bland transarterial embolization (bland TAE), and are presently controlled with only 2 liver metastases of <20 mm. The present case showed that bland TAE can achieve long-term prevention of the progression of liver metastases of ACC. The ultraselective bland TAE for selective embolization supported by the latest computed tomography analysis techniques during arteriography could minimize liver damage caused by embolization and allowed multiple treatments which prolonged survival. We conclude that bland TAE can be effective for controlling liver metastases of ACC.
