title: Radical nephrectomy for renal cell carcinoma: Is adrenalectomy necessary?
abstract: OBJECTIVE
  The role of simultaneous adrenalectomy in combination with radical nephrectomy in the treatment for renal cell carcinoma (RCC) remains controversial. With nephron-sparing surgery being commonly applied, the indication for adrenalectomy has to be critically assessed.
  
  
  METHODS
  In a retrospective analysis the outcome of 589 patients, who underwent ipsilateral adrenalectomy along with radical nephrectomy in the treatment for RCC between 1985 and 1997 at our institution, was evaluated. The mean follow-up time was 34 months (range 1-95).
  
  
  RESULTS
  Histologically an ipsilateral adrenal metastasis was found in 19/589 patients (3.2%). 16/19 patients had >/= T3, 3/19 had T1 tumours. The average size of the primary tumours with adrenal metastasis was 7.8 cm (range 2.3-13) in diameter with no preferential primary tumour site within the kidney (6/19 upper, 4/19 middle and 9/19 lower third). Only 4/19 patients had suspect adrenal findings in preoperative diagnostics (ultrasound, CT scan). 6/19 (31.5%) patients with adrenal metastasis are alive without evidence of disease at a mean of 41 months (range 11-95) after surgery for RCC.
  
  
  CONCLUSIONS
  The probability of adrenal metastasis correlates with primary tumour stage, but not with its location within the kidney. The preoperative diagnostics are not reliable concerning small adrenal metastases. We thus still recommend simultaneous adrenalectomy in those cases where radical nephrectomy in patients with RCC is indicated.
