ABSTRACT
BACKGROUND:
The anatomic boundaries of lymphadenectomy for adrenocortical carcinoma (ACC) are not defined.METHODS:
Adults undergoing resection of ACC were included. Locations were categorized based on positive LN locations on final pathology.RESULTS:
Of 231 resected ACC, 6% had positive LN during initial resection. Positive LN in left ACC (n = 7) were 2 para-aortic, 2 left renal-hilar, 1 para-aortic and left renal-hilar and 1 unknown, while for right ACC (n = 7) 2 para-caval, 1 para-caval and right renal-hilar, 1 inter-aortocaval, 1 celiac, 1 para-aortic, and 1 unknown. Of 55 resections for recurrent ACC, positive LN in left ACC (n = 2) were 1 para-aortic, and 1 para-aortic with left renal-hilar, while LN for right ACC (n = 7) 2 inter-aortocaval, 2 right renal-hilar, 2 para-caval and one retrocrural.CONCLUSION:
The most common LN metastases are para-caval for right, and para-aortic and left renal-hilar for left ACC. Further studies are necessary to determine the boundaries of lymphadenectomy in ACC resection.Key words
