What
is Adrenal Cancer?
|
|
Adrenal cancer takes place in the adrenal glands
which are located just above the kidneys. The adrenal glands are
responsible for creating hormones. There are two main types of
adrenal cortical tumors: benign tumors and malignant tumors.
Benign tumors in the adrenal gland are called adenomas and
malignant tumors are called adrenal cortical carcinomas. Benign
tumors do not spread cancer and can be removed through surgery.
|
|
|
They do, however, have the ability to cause
hormonal complications. Benign tumors in the adrenal gland may
secrete an excess of hormones that cause Cushing's or Conn's syndrome.
Malignant tumors in the adrenal glands have the ability to spread
cancer cells to other sites in the
body. When adrenal
cancer has time to advance in
staging, the results are often deadly. Malignant tumors
need to be removed through a surgery called an
adrenalectomy and treated with the chemotherapy drug mitotane. |

Causes of Adrenal Cancer:
The direct cause of adrenal
cancer is not
known. While cell mutations are responsible for causing
the disease, researchers do not know what causes a
person's cells to mutate. Some cell mutations could be
inherited from the DNA instructions of a parent, but
only a small percentage. Outside variables such as
radiation and carcinogens in the air could possibly
cause cell mutations as well. It is believed that most
adrenal cancer causing cell mutations occur after birth
for no apparent reason at all. Not knowing a direct
cause for adrenal cancer makes the disease difficult to
prevent and near impossible to see coming before it is
diagnosed. |
Adrenal Cancer Prevention:
Adrenal
cancer cannot be prevented.
Researchers have not yet found a way to prevent the cell
mutations that cause had adrenal
cancer. Also,
spending money, time and research to stop something that
only might happen because a parent DNA that caused cell
mutations is not realistic. The best advice that can be
given to prevent death caused by adrenal
cancer is to
avoid radiation and carcinogens and be screened at the
doctor to check for adrenal
cancer signs. Catching the
disease in its earliest stage gives patients the best
chance of surviving adrenal
cancer. |
Types of Adrenal Cancer:
Adrenal
cancer can exist in two different
places in the adrenal gland, the adrenal cortex, and the
adrenal medulla. These two areas can create two types of
tumors each: |
Adrenal Cortex:
Adrenocortical adenoma tumors are
benign and quite. common. They do no cause or
spread cancer. Some of them cause hormonal problems as a
result of Cushing's and Conn's
syndromes. Adrenocortical carcinoma tumors are
malignant, aggressive, and highly functional.
These tumors grow quickly and are usually not
discovered until they are in their more advanced
stages. The prognosis for these tumors is very
poor.
|
|
Adrenal Medulla:
Neuroblastoma tumors are
aggressive and usually occur in young children.
Despite the ability of these tumors to spread to
the liver, skin and blood, neuroblastomas are
highly treatable. Surgery can be performed to
remove the tumors and radiation and chemotherapy
can treat neuroblastomas that have metastasized.n>
Pheochromocytoma tumors are malignant only 10%
of the time. Pheochromocytomas can produce
dangerous levels of adrenaline resulting in
life-threatening high blood pressure. Other
symptoms that may result from dangerous levels
of adrenaline being released are headaches,
anxiety, and panic attacks. Treatment options
include surgery to remove the tumor and
anti-adrenergic drugs. |
|
Adrenal Cancer Symptoms:
Adrenal
cancer has different sets
of symptoms depending on if the androgen or
estrogen symptoms take place. Androgen and
estrogen symptoms can occur in either males or
females. Symptoms are usually more evident in
children than in adults because adults have
already gone through so many hormonal changes.
Since symptoms show themselves more in children,
children have a better chance of being diagnosed
with adrenal cancer |
|
Androgen
symptoms that can effect both male and female
children include: |
|
Excess growth of
facial, pubic and underarm hairr
|
Males will have an enlargement of the penis
|
Females will have an enlargement of the clitoris |
|
Estrogen symptoms that can effect both
male and female children include: |
|
Early
puberty in girls resulting in periods at
a young age and enlarged breastss
|
|
|
Adrenal Cancer Diagnosis:
An adrenal
cancer diagnosis can be made after a
series of tests have been completed. A
diagnosis cannot be made through only
discussions and symptoms. There are
three key areas of testing that
contribute to diagnosing adrenal
cancer |
|
Imaging Tests
Include:
|
|
X-rayss
|
CT Scans
|
MRI Scans
|
Ultrasounds
|
|
Blood and Urine Tests Include: |
|
High Cortisol Level Testss
|
High Aldosterone Level Tests
|
High Androgen and Estrogen Level Tests
|
|
Physical Tests Include:
|
|
Biopsyy
|
|
|
Adrenal Cancer Staging:
Adrenal
cancer stages are classified
using the model created by the American
Joint Committee on Cancer. The AJCC uses
a TNM model as part of the staging
system for adrenal
cancer. The letters
"T", "N" and "M" refer to the tumor,
lymph nodes and metastasizing of the
cancer. Numbers or letters are placed
next to each letter to characterize how
severe each aspect of the TNM model is.
Higher numbers for each letter may mean
a higher stage is needed to describe the
current stage the adrenal
cancer is in.
Five-year survival rates for early
stages are relatively favorable at 65%.
For adrenal
cancer, stages 1 and 2 are
considered early stages. The third and
fourth stages have 40% and 10% five-year
survival rates, respectively. These
percentages are not based on a large
sample of people, as adrenal
cancer |
|
Adrenal Cancer Prognosis:
Adrenal
cancer prognoses depend on the
type of tumor a patient has along with
their age and past medical history. The
stage a tumor is in is the most
important factor for determining a
prognosis. Benign and malignant tumors
have an over all 65% five-year survival
rate after removal. Malignant tumors
alone have a five-year survival rate at
about 40% after removal of a tumor. If a
tumor is able to reach the fourth stage
in it's progression, patients only have
about a 10% chance of living at least
five years.
Adenocortical carcinomas present the
worst prognosis of any adrenal gland
tumors. Most adrenocortical adenoma and
pheochromocytoma tumors are benign
offering a positive prognosis.
Neuroblastomas are rare in that they can
spread to distant sites in the
body |
|
Adrenal Cancer Treatment:
Treatment options for adrenal
cancer are
limited to surgery to remove
cancer |
|
Surgery:
Open surgery involves a large incision
across the belly or just below the rib
through a patient's back. This is an
invasive surgery that will require a
long hospital stay. Any organs that have
been infected with
cancer will have to
be removed though the belly. Large
tumors are removed through open surgery.
Laparoscopy is a procedure characterized
by three to five small incisions through
a patient's abdomen. A tiny video camera
is attached to the doctor's tools and
this offers the doctor the best view
possible inside the
body |
|
Chemotherapy:
Chemotherapy is not used to cure adrenal
cancer. It is used to control hormonal
symptoms patients may experience. Even
benign tumors can cause Cushing's and
Cronn's syndromes. Those symptoms result
in an excess of hormones to be secreted
from the adrenal glands. Mitotane, a
chemotherapy drug, help to reduce the
symptoms suffered as a result of tumors
in the adrenal glands. Mitotane can also
be used to prevent
cancer from
reemerging and stopping it from
spreading beyond the adrenal glands. |
