Treatment of adrenal metastases after hepatic resection of a hepatocellular carcinoma.
BACKGROUND
The adrenal gland is a common site of extrahepatic metastases from a hepatocellular carcinoma (HCC). However, treatment of adrenal metastases has not been well characterized.


METHODS
Of 562 patients who underwent hepatic resection for a HCC, 91 developed extrahepatic metastases. We reviewed the medical records of 10 patients with adrenal metastases (9 males and 1 female; mean age 63 years at the time of hepatic resection).


RESULTS
The mean diameter of the primary tumors was 5 cm, and all were located in the right lobe of the liver. The mean interval from hepatic resection to recurrence was 18 months. Seven patients underwent treatment of intrahepatic recurrence. To treat the adrenal metastases, surgical resection was performed in 4 patients, and transcatheter arterial embolization was performed in 1 patient. The patients treated had no other extrahepatic metastases. The mean diameter of the resected adrenal tumors was 6 cm. There was no hospital mortality. With surgical resection, 1 patient has been alive 63 months after recurrence.


CONCLUSIONS
Adrenal metastases from a HCC were often large at the time of diagnosis. Since surgical resection was a safe procedure, and some patients could be alive for a long time, it should be performed whenever possible.
