The indications for adrenalectomy in cases of metastatic adrenal tumor remain controversial. To clarify indications and outcomes of adrenalectomy for adrenal metastasis, we performed a retrospective review of all 8 patients who underwent adrenalectomy for adrenal metastasis between 1990 and 2006 in Asahikawa Medical College Hospital. The Primary tumor was renal cell carcinoma in 2 cases, and eccrine poro carcinoma, rectal cancer, lung cancer, melanoma, bladder cancer and cancer of unknown origin in 1 case each. Open adrenalectomy was performed in all cases, including 1 case that was converted from laparoscopic adrenalectomy. Of the 4 patients with solitary adrenal metastasis, 3 were considered tumor-free after adrenalectomy, while the remaining patient was not due to unresectable primary tumor. Of the 3 patients with complete resection, one remained alive as of 88 months after adrenalectomy but was then lost to follow-up, and the other 2 patients remain alive 12 and 7 months after adrenalectomy. Of the 2 patients with other resectable metastasis who were tumor-free after removal of all metastases, one was alive 31 months postoperatively and the other died 23 months after operation. The remaining 2 cases with other unresectable metastasis died within 6 months after adrenalectomy. At least in cases of solitary adrenal metastasis, adrenalectomy can be effective if other valid methods are unavailable.
