Adrenal carcinoma

Definition:

Adrenocortical carcinoma (ACC) is a rare endocrine malignancy defined by a heterogeneous clinical presentation, dismal prognosis, and lack of effective therapeutic regimens. The incidence of ACC ranges from 0.5 to 2 cases per million people per year, accounting for 0.02% of all reported cancers. Unfortunately, most patients present with metastatic disease which reduces the 5 year survival rate to less than 10%. Oncogenes and tumor-suppressor genes involved in adrenal carcinomas include mutations in the p53 tumor-suppressor gene and rearrangements of the chromosomal locus 11p15.5 associated with IGF II hyperexpression. Deletions of the ACTH receptor gene have recently been found in undifferentiated adenomas and in aggressive ACCs.
