Adrenocortical carcinoma is a rare cancer affecting the outside of the adrenal glands (adrenal cortex). These glands are on top of each kidney and are responsible for producing certain hormones and keeping blood pressure at normal levels. Adrenocortical carcinoma is relatively frequent in children compared to many other cancers, although the cancer may also affect adults. Girls are more often affected than boys. Symptoms of adrenocortical carcinoma may include pain in the abdomen, hypertension, weight gain, frequent urination and possibly deepening of the voice. These symptoms are due to the tumors causing excess secretion of hormones from the adrenal glands.[12165]
Adrenocortical carcinoma may develop by chance alone, but at least 50% of the cancers are thought to be hereditary. There are a number of genes that have changes (mutations) that can cause an adrenocortical carcinoma, including TP53 and IGF2. There have been reports of both autosomal dominant inheritance and autosomal recessive inheritance.[12164]
An adrenocortical carcinoma is diagnosed based on urine tests for abnormal levels of cortisol, the hormone released by the adrenal glands. Blood tests can also be conducted to measure levels of potassium and sodium in the blood. A CT scan or MRI may be used to search for a visible tumor in the adrenal cortex. Treatment options include surgical removal of the tumor, which is important to achieve a good long-term outlook. Chemotherapy, specifically a drug called mitotane, can be used to try to remove any remaining cancer after surgery.[12165][12166]
