Metastasis to one or both adrenal glands is the most common form of malignant adrenal lesion, and the second most common adrenal tumor after benign adenomas. [4] Primary tumors in such cases are most commonly from lung cancer (39%), breast cancer (35%), malignant melanoma , gastrointestinal tract cancer , pancreas cancer , and renal cancer .
Adrenocortical carcinoma (ACC) is an aggressive cancer originating in the cortex (steroid hormone-producing tissue) of the adrenal gland.. Adrenocortical carcinoma is remarkable for the many hormonal syndromes that can occur in patients with steroid hormone-producing ("functional") tumors, including Cushing's syndrome, Conn syndrome, virilization, and feminization.
The most common extra-adrenal sites of metastases are the lymph nodes, lung, liver, and bone. [135] There have been several studied risk factors associated with the development of metastatic disease — while the patients genetic background plays an important role, the initial age of presentation and size of the tumor lead to negative outcomes ...
Neuroblastoma often spreads to other parts of the body before any symptoms are apparent, and 50 to 60% of all neuroblastoma cases present with metastases. [8] The most common location for neuroblastoma to originate (i.e., the primary tumor) is in the adrenal glands. This occurs in 40% of localized tumors and in 60% of cases of widespread disease.
Rarely (5–12%), the adrenal tumor may be cancerous (adrenocortical carcinoma), requiring adrenalectomy. Rarer still, the mass may be a metastatic cancer that spread from another location, such as the kidney or lung. If the metastasis is isolated to the adrenal gland, it may be a candidate for adrenalectomy. [5] [7]
Metastases to the liver can be treated by several types of hepatic artery treatments based on the observation that tumor cells get nearly all their nutrients from the hepatic artery, while the normal cells of the liver get about 70–80 percent of their nutrients and 50% their oxygen supply from the portal vein, and thus can survive with the ...
When the same type of tumor is found in the adrenal gland, they are referred to as a pheochromocytoma. They are rare tumors, with an overall estimated incidence of 1 in 300,000. [1] There is no test that determines benign from malignant tumors; long-term follow-up is therefore recommended for all individuals with paraganglioma. [2]
