Adrenocortical Carcinoma
Adrenocortical carcinoma is a rare disease in which malignant
(cancer) cells form in the outer layer of the adrenal gland.
There are two adrenal glands. The adrenal glands are small and shaped like a
triangle. One adrenal gland sits on top of each kidney. Each adrenal gland has
two parts. The outer layer of the adrenal gland is the adrenal cortex. The
center of the adrenal gland is the adrenal medulla.
The adrenal cortex makes important hormones that:
- Balance the water and salt in the body.
- Help keep blood pressure normal.
- Help manage the body's use of protein, fat, and carbohydrates.
- Cause the body to have masculine or feminine characteristics.
The adrenal medulla makes hormones that help the body react to
stress.
Adrenocortical carcinoma is also called cancer of the adrenal
cortex. A tumor of the adrenal cortex may be functioning (makes more hormones
than normal) or nonfunctioning (does not make hormones). The hormones made by
functioning tumors may cause certain signs or symptoms of disease.
Cancer that forms in the adrenal medulla is called
pheochromocytoma.
Having certain genetic conditions increases the risk of
developing adrenocortical carcinoma.
Anything that increases your risk of getting a disease is called a risk
factor. Having a risk factor does not mean that you will get cancer; not having
risk factors doesn’t mean that you will not get cancer. People who think they
may be at risk should discuss this with their doctor. Risk factors for
adrenocortical carcinoma include having the following hereditary diseases:
- Li-Fraumeni syndrome.
- Beckwith-Wiedemann syndrome.
- Carney complex.
Possible signs of adrenocortical carcinoma include pain in the
abdomen and certain physical changes.
These and other symptoms may be caused by adrenocortical carcinoma:
- A lump in the abdomen.
- Pain the abdomen or back.
A nonfunctioning adrenocortical tumor may not cause symptoms in
the early stages.
A functioning adrenocortical tumor makes too much of a certain hormone (cortisol,
aldosterone, testosterone, or estrogen.)Having too much of a certain hormone may
cause the following symptoms:
Too much cortisol
- Weight gain in the face, neck, and trunk of the body and thin arms and
legs.
- Growth of fine hair on the face, upper back, or arms.
- A round, red, full face.
- A lump of fat on the back of the neck.
- A deepening of the voice and swelling of the sex organs or breasts in
both males and females.
- Muscle weakness.
- High blood sugar.
- High blood pressure.
Too much aldosterone
- High blood pressure.
- Muscle weakness or cramps.
- Frequent urination.
- Feeling thirsty.
Too much testosterone (in women)
- Growth of fine hair on the face, upper back, or arms.
- Acne.
- Balding.
- A deepening of the voice.
- No menstrual periods.
Men who make too much testosterone do not usually have symptoms.
Too much estrogen (in women)
- Irregular menstrual periods in women who have not gone through
menopause.
- Menstrual bleeding in women who have gone through menopause.
Too much estrogen (in men)
- Growth of breast tissue.
- Lower sex drive.
- Impotence.
These and other symptoms may be caused by adrenocortical
carcinoma. Other conditions may cause the same symptoms. A doctor should be
consulted if any of these problems occur.
Imaging studies and tests that examine the blood and urine are
used to detect (find) and diagnose adrenocortical carcinoma.
The tests and procedures used to diagnose adrenocortical carcinoma depend on
the patient's symptoms. The following tests and procedures may be used:
- Physical exam and history:
An exam of the body to check general
signs of health, including checking for signs of disease, such as lumps or
anything else that seems unusual. A history of the patient’s health habits
and past illnesses and treatments will also be taken.
- Twenty-four-hour urine test:
A test in which urine is collected for
24 hours to measure the amounts of cortisol or 17-ketosteroids. A higher
than normal amount of these in the urine may be a sign of disease in the
adrenal cortex.
- Low- dose dexamethasone suppression test:
A test in which one or
more small doses of dexamethasone is given. The level of cortisol is checked
from a sample of blood or from urine that is collected for three days.
- High-dose dexamethasone suppression test:
A test in which one or
more high doses of dexamethasone is given. The level of cortisol is checked
from a sample of blood or from urine that is collected for three days.
- Blood chemistry study:
A procedure in which a blood sample is
checked to measure the amounts of certain substances, such as potassium or
sodium, released into the blood by organs and tissues in the body. An
unusual (higher or lower than normal) amount of a substance can be a sign of
disease.
- Blood tests:
Tests to measure the levels of testosterone or estrogen
in the blood. A higher than normal amount of these hormones that may be a
sign of adrenocortical carcinoma.
- CT scan (CAT scan):
A procedure that makes a series of detailed
pictures of areas inside the body, taken from different angles. The pictures
are made by a computer linked to an x-ray machine. A dye may be injected
into a vein or swallowed to help the organs or tissues show up more clearly.
This procedure is also called computed tomography, computerized tomography,
or computerized axial tomography.
- MRI (magnetic resonance imaging):
A procedure that uses a magnet,
radio waves, and a computer to make a series of detailed pictures of areas
inside the body. This procedure is also called nuclear magnetic resonance
imaging (NMRI). An MRI of the abdomen is done to diagnose adrenocortical
carcinoma.
- Adrenal angiography:
A procedure to look at the arteries and the
flow of blood near the adrenal gland. A contrast dye is injected into the
adrenal arteries. As the dye moves through the blood vessel, a series of
x-rays are taken to see if any arteries are blocked.
- Adrenal venography:
A procedure to look at the adrenal veins and the
flow of blood near the adrenal gland. A contrast dye is injected into an
adrenal vein. As the contrast dye moves through the vein, a series of x-rays
are taken to see if any veins are blocked. A catheter (very thin tube) may
be inserted into the vein to take a blood sample, which is checked for
abnormal hormone levels.
- PET scan (positron emission tomography scan):
A procedure to find
malignant tumor cells in the body. A small amount of radioactive glucose
(sugar) is injected into a vein. The PET scanner rotates around the body and
makes a picture of where glucose is being used in the body. Malignant tumor
cells show up brighter in the picture because they are more active and take
up more glucose than normal cells do.
Certain factors affect the prognosis (chance of recovery) and
treatment options.
The prognosis (chance of recovery) and treatment options depend on the
following:
- The stage of the cancer (the size of the tumor and whether it is in the
adrenal gland only or has spread to other places in the body).
- Whether the tumor can be completely removed in surgery.
- Whether the cancer has been treated in the past.
- The patient's general health.
Adrenocortical carcinoma may be cured if treated at an early
stage.
Stages of Adrenocortical Carcinoma
After adrenocortical carcinoma has been diagnosed, tests are done to find
out if cancer cells have spread within the adrenal gland or to other parts of
the body.
The process used to find out if cancer has spread within the
adrenal gland or to other parts of the body is called staging. The information
gathered from the staging process determines the stage of the disease. It is
important to know the stage in order to plan treatment. The following tests and
procedures may be used in the staging process:
- CT scan (CAT scan):
A procedure that makes a series of detailed
pictures of areas inside the body, such as the abdomen or chest, taken from
different angles. The pictures are made by a computer linked to an x-ray
machine. A dye may be injected into a vein or swallowed to help the organs
or tissues show up more clearly. This procedure is also called computed
tomography, computerized tomography, or computerized axial tomography.
- MRI (magnetic resonance imaging) with gadolinium:
A procedure that
uses a magnet, radio waves, and a computer to make a series of detailed
pictures of areas inside the body. A substance called gadolinium may be
injected into a vein. The gadolinium collects around the cancer cells so
they show up brighter in the picture. This procedure is also called nuclear
magnetic resonance imaging (NMRI).
- Adrenal angiography:
A procedure to look at the arteries and the
flow of blood near the adrenal gland. A contrast dye is injected into the
adrenal arteries. As the dye moves through the blood vessel, a series of
x-rays are taken to see if any arteries are blocked.
- Adrenal venography:
A procedure to look at the adrenal veins and the
flow of blood near the adrenal gland. A contrast dye is injected into an
adrenal vein. As the contrast dye moves through the vein, x-rays are taken
to see if any veins are blocked. A catheter (very thin tube) may be inserted
into the vein to take a blood sample, which is checked for abnormal hormone
levels.
- Cavagram:
A procedure to look at the inferior vena cava and the flow
of blood through the inferior vena cava. A contrast dye is injected into a
blood vessel. As the contrast dye moves through the blood vessel to the
inferior vena cava, a series of x-rays are taken to see if there are any
changes to the inferior vena cava and the flow of blood through the inferior
vena cava.
- Ultrasound exam:
A procedure in which high-energy sound waves
(ultrasound) are bounced off internal tissues or organs, such as the vena
cava, and make echoes. The echoes form a picture of body tissues called a
sonogram.
- Adrenalectomy:
A procedure to remove the entire adrenal gland. A
tissue sample is viewed under a microscope by a pathologist to check for
signs of cancer.
The following stages are used for adrenocortical carcinoma:

Pea, peanut, walnut, and lime show tumor sizes.
Stage I
In stage I, the tumor is 5 centimeters or smaller and is found only in the
adrenal gland.
Stage II
In stage II, the tumor is larger than 5 centimeters and is found only in the
adrenal gland.
Stage III
In stage III, the tumor can be any size and may have spread to
fat or lymph nodes near the adrenal gland.
Stage IV
In stage IV, the tumor can be any size and has spread:
- to fat or organs and to lymph nodes near the adrenal gland; or
- to other parts of the body. Adrenocortical carcinoma commonly spreads to
the lung, liver, bones, and peritoneum (the tissue that lines the abdominal
wall and covers most of the organs in the abdomen).
Recurrent Adrenocortical Carcinoma
|Recurrent adrenocortical carcinoma is cancer that has recurred (come back)
after it has been treated. The cancer may come back in the adrenal cortex or in
other parts of the body.
Treatment option overview
There are different types of treatment for patients with adrenocortical
carcinoma.
Different types of treatments are available for patients with
adrenocortical carcinoma. Some treatments are standard (the currently used
treatment), and some are being tested in clinical trials. Before starting
treatment, patients may want to think about taking part in a clinical trial. A
treatment clinical trial is a research study meant to help improve current
treatments or obtain information on new treatments for patients with cancer.
When clinical trials show that a new treatment is better than the standard
treatment, the new treatment may become the standard treatment.
Clinical trials are taking place in many parts of the country.
Information about ongoing clinical trials is available from the NCI Web site.
Choosing the most appropriate cancer treatment is a decision that ideally
involves the patient, family, and health care team.
Three types of standard treatment are used:
Surgery
Surgery to remove the adrenal gland (adrenalectomy) is often used to treat
adrenocortical carcinoma. Sometimes the nearby lymph nodes are also removed.
Radiation therapy
Radiation therapy is a cancer treatment that uses high-energy x-rays or
other types of radiation to kill cancer cells or keep them from growing. There
are two types of radiation therapy. External radiation therapy uses a machine
outside the body to send radiation toward the cancer. Internal radiation therapy
uses a radioactive substance sealed in needles, seeds, wires, or catheters that
are placed directly into or near the cancer. The way the radiation therapy is
given depends on the type and stage of the cancer being treated.
Chemotherapy
Chemotherapy is a cancer treatment that uses drugs to stop the growth of
cancer cells, either by killing the cells or by stopping them from dividing.
When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs
enter the bloodstream and can reach cancer cells throughout the body (systemic
chemotherapy). When chemotherapy is placed directly into the spinal column, an
organ, or a body cavity such as the abdomen, the drugs mainly affect cancer
cells in those areas (regional chemotherapy). The way the chemotherapy is given
depends on the type and stage of the cancer being treated.
Mitotane may be used to treat adrenocortical carcinoma. Mitotane
stops the adrenal cortex from making hormones and relieves symptoms caused by
the hormones.
New types of treatment are being tested in clinical trials.
These include the following:
Biologic therapy
Biologic therapy is a treatment that uses the patient's immune system to
fight cancer. Substances made by the body or made in a laboratory are used to
boost, direct, or restore the body's natural defenses against cancer. This type
of cancer treatment is also called biotherapy or immunotherapy.
This summary section refers to specific treatments under study
in clinical trials, but it may not mention every new treatment being studied.
Information about ongoing clinical trials is available from the NCI Web site.
Treatment options by stage
Stage I Adrenocortical Carcinoma
Treatment of stage I adrenocortical carcinoma is usually surgery (adrenalectomy).
Lymph nodes may be removed if they are larger than normal.
Stage II Adrenocortical Carcinoma
Treatment of stage II adrenocortical carcinoma is usually surgery (adrenalectomy).
Lymph nodes may be removed if they are larger than normal.
Stage III Adrenocortical Carcinoma
Treatment of stage III adrenocortical carcinoma may include the following:
-
Surgery (adrenalectomy with or without removal of lymph
nodes).
-
A clinical trial of radiation therapy for tumors that cannot
be removed by surgery.
-
A clinical trial of mitotane for tumors that cannot be
completely removed by surgery.
Stage IV Adrenocortical Carcinoma
Treatment of stage IV adrenocortical carcinoma may include the following as
palliative therapy to relieve symptoms and improve the quality of life:
- Mitotane therapy.
- Radiation therapy to bones where cancer has spread.
- Chemotherapy followed by surgery to remove the tumor.
- Surgery to remove the tumor.
- Surgery to remove cancer from places where it has spread.
- A clinical trial of chemotherapy or biologic therapy.
Treatment options for Recurrent Adrenocortical Carcinoma
Treatment of recurrent adrenocortical carcinoma may include the following as
palliative therapy to relieve symptoms and improve the quality of life:
- Surgery to remove the tumor.
- Surgery to remove the cancer from places where it has spread.
- A clinical trial of chemotherapy or biologic therapy.
