Adrenocortical carcinoma is a rare cancer in your adrenal cortex, the outer layer of your adrenal glands. In this condition, your glands have tumors that release large amounts of hormones. The tumors may grow large enough to press on nearby organs. Healthcare providers can treat the condition with surgery and medication, but it often comes back (recurs).

Adrenocortical carcinoma is cancer in your adrenal cortex, the outer layer of your adrenal glands. These glands are on top of your kidneys and produce hormones that, among other things, manage your body’s metabolism, blood pressure and how you react to stress.

In adrenocortical carcinoma, there are cancerous tumors on your adrenal glands that may release abnormally large amounts of hormones. The flood of hormones may affect how your body works. Fast-growing tumors may press on nearby organs. In some instances, healthcare providers can treat adrenocortical carcinoma, but the condition often comes back (recurs).
This condition typically affects adults, but children sometimes develop it, too. This article focuses on adrenocortical carcinoma in adults.
There are two types — functioning and non-functioning — that cause different symptoms:
Adrenocortical carcinoma is very rare even, though it’s the most common type of adrenal cancer. Each year, about 1 in 1 million people receive a diagnosis of adrenocortical carcinoma.
You can have this condition without having symptoms. Studies show that 20% to 30% of adrenocortical carcinoma diagnoses happen after healthcare providers do imaging tests for unrelated health issues. When adrenocortical carcinoma symptoms develop, they may include:

It’s very aggressive because the tumors can grow very quickly and spread (metastasize) from your adrenal gland to other areas of your body, including your lungs or bones.
Researchers don’t know the exact cause. Some people develop adrenocortical carcinoma because they have inherited conditions that increase the risk that they’ll develop the condition.
In other cases, certain genetic mutations (changes) appear to increase risk. For example, research shows changes in the tumor suppressor genes TP53 and IGF2 appear to drive adrenocortical carcinoma. Tumor suppressor genes manage cell growth. When these genes change, your cells may multiply uncontrollably and become cancerous tumors.
Having any of the following conditions increases your risk of developing adrenocortical carcinoma:
It can spread (metastasize) very quickly. Cancer that spreads from your adrenal gland to other areas of your body is more difficult to treat. Tumors that release certain hormones may cause conditions including:
If tests for other issues reveal a tumor on your adrenal gland or you have certain symptoms, your healthcare provider will do the following:
Your provider may do a biopsy to confirm that a tumor is cancerous, as well as obtain tissue samples.
Healthcare providers use cancer staging systems to plan treatment and develop a prognosis (what you can expect to happen after treatment). They establish adrenocortical carcinoma stages by evaluating tumor size and location and whether the tumor has spread to nearby lymph nodes or other more distant organs. Adrenocortical carcinoma stages include:

Cancer staging information can be confusing, so don’t hesitate to ask your healthcare provider to explain the system and how it applies to your situation.
The most common treatment is adrenalectomy to remove one or both of your adrenal glands. Often, healthcare providers prescribe additional medications like:
In some cases, however, the condition isn’t diagnosed until after tumors have grown too large to be safely removed with surgery. In those instances, healthcare providers may treat cancerous tumors with chemotherapy. This treatment won’t eliminate the cancerous tumors, but it can ease symptoms and slow down tumor growth.
You also may want to consider palliative care as part of your treatment. Palliative care is treatment that helps manage disease symptoms and treatment side effects. Palliative care specialists can also help you with emotional and mental health support.

Surgery and medications may cause different complications or side effects. For example, surgery to remove an adrenal gland may:
Your healthcare provider may recommend that you take mitotane for two to five years after surgery. Mitotane side effects may include:
No, it can’t. Researchers know about half of all cases of adrenocortical carcinoma happen when certain genes mutate and create cancerous cells that multiply and become tumors. But they don’t know what triggers those mutations, so they can’t recommend ways you could prevent them from happening.
But some inherited disorders increase your risk of developing this condition. If you have a family history of one of these disorders, talk to a healthcare provider about genetic tests that detect the mutations that cause these disorders.

Overall, 50% of people with adrenocortical carcinoma were alive five years after diagnosis. Survival rates vary widely, depending on factors like:
Five-year survival rates by stage are:
Stage | Survival rate |
---|---|
Stages I and II | 74% |
Stage III | 54% |
Stage IV | 38% |

Stages I and II | |

Stage III | |

Stage IV | |

Survival rate information may make you feel anxious or afraid. That’s understandable. Try to remember that these estimates are based on experiences that happened in the past. Experts measure survival rates every five years. Many things can change in five years that may make a difference. It’s also important to remember that survival rates aren’t estimates for how long you will live.
If you have specific questions about cancer survival rates, talk to your healthcare provider. They’re your best resource because they know your situation.
Adrenocortical carcinoma is a rare cancer that often comes back — two challenges that may make you feel afraid, isolated or anxious. Fortunately, there are steps you can take that may help:
Adrenocortical carcinoma often comes back (recurs), most commonly within the first two years after surgery Your provider will set up a schedule of follow-up appointments to monitor for signs of recurrence. For example, you may have:
Adrenocortical carcinoma is a rare disease. You may have many questions about what you can expect. Here are some questions you may find helpful:
Adrenocortical carcinoma is a rare, aggressive cancer that affects your adrenal gland. It may not cause symptoms, and many people receive a diagnosis after tests for a completely different medical condition. You may be upset and frightened by your diagnosis and the news that adrenocortical carcinoma often comes back after treatment.
If you’re feeling overwhelmed by your situation, take your time to understand what’s happening. Don’t hesitate to ask questions about treatment, including how it may affect you. Your healthcare providers will understand why you may have certain reactions. They’ll be there to answer your questions from your diagnosis, through treatment and throughout the years of follow-up.
