Abstract Background. Metachronous solitary metastasis of renal cell carcinoma (RCC) to the contralateral adrenal gland is very rare. We assessed the clinocopathological findings of such patients who received adrenalectomy. Methods. We retrospectively reviewed the records of all 495 patients who underwent nephrectomy for RCC; excluding those in stage IV, between 1980 and 1993. Of these patients, 5 who showed metachronous solitary metastasis to the contralateral adrenal gland, and also received adrenalectomy were the subjects of this study. Results. The adrenal metastasis was found between 14 and 132 months (median, 81 months) after nephrectomy. After the solitary adrenalectomy, patient survival ranged from 450 to 2160 days (median, 660 days); 2 patients were alive with no evidence of disease at 660 and 1830 days, respectively, and 3 patients died of this disease, at 450, 480, and 2160 days, respectively, after adrenalectomy. The overall survival rate was 100% at 5 years, 80% at 6 years, 60% at 7 years, and 40% thereafter. The 2 patients with no evidence of disease did not receive steroid supplementation, because they had not received ipsilateral adrenalectomy. No significant difference was observed between survivors and non-survivors in terms of clinicopathological factors such as affected side, location of the tumor, tumor size of primary/metastatic lesion, and stage or grade of primary/metastatic lesion. From the viewpoint of outcome, patients with early recurrence tended to show an unfavorable prognosis compared with prognosis in those with late recurrence. Conclusion. The prediction of outcome in patients with RCC who undergo, adrenalectomy for metachronous solitary metastasis to the contralateral adrenal gland is difficult. Although the factors that affect prognosis are uncertain, long-term observation for unusual metachronous metastasis to the contralateral adrenal gland is mandatory in patients with RCC.
