On the necessity of adrenal extirpation combined with radical nephrectomy.

Adrenal metastasis of renal cell carcinoma usually is an autopsy finding and seldom a clinical diagnosis. The incidence of ipsilateral suprarenal gland involvement also can be identified by histological examination of the organ with radical nephrectomy. The necessity of adrenalectomy performed in combination with nephrectomy is discussed. After a retrospective examination of our patients we discovered 8 adrenal metastases among 138 radical nephrectomies. Five patients who also had metastases in the lymph nodes (stages pN1 to pN2) died after an average of 26.4 months. Three patients without lymph node involvement are free of tumor. In these cases routine adrenalectomy must be regarded as a possible curative treatment.
