Afinitor is the trade name for the generic name drug everolimus. In some cases,
health care professionals may use the generic name everolimus
when referring to the trade drug name Afinitor.
Afinitor is a targeted therapy and is classified as an mTOR inhibitor.
What Afinitor Is Used For:

sunitinib and sorafenib treatment failure.

post menopausal women, after letrozole or anastrozole treatment failure.
Note: If a drug has been approved
for one use, physicians may elect to use this same drug for other problems if they
believe it may be helpful.

care team. They can prescribe medications and/or offer other suggestions that are
effective in managing such problems.
Monitoring and Testing While Taking Afinitor:
You will be checked regularly by your doctor while
you are taking Afinitor, to monitor side effects and check your response to therapy.
Periodic blood work will be obtained to monitor your complete blood count (CBC)
as well as the function of other organs (such as your kidneys and liver) will also
be ordered by your doctor.
How Afinitor Works:
Targeted therapy is the result
of about 100 years of research dedicated to understanding the differences between
cancer cells and normal cells. To date, cancer treatment has focused primarily
on killing rapidly dividing cells because one feature of cancer cells is that they
divide rapidly. Unfortunately, some of our normal cells divide rapidly too,
causing multiple side effects.
Targeted therapy is about identifying other features
of cancer cells. Scientists look for specific differences in the cancer cells
and the normal cells. This information is used to create a targeted therapy
to attack the cancer cells without damaging the normal cells, thus leading to fewer
side effects. Each type of targeted therapy works a little bit differently
but all interfere with the ability of the cancer cell to grow, divide, repair and/or
communicate with other cells.
There are different types of targeted therapies, defined
in three broad categories. Some targeted therapies focus on the internal components
and function of the cancer cell. The targeted therapies use small molecules
that can get into the cell and disrupt the function of the cells, causing them to
die. There are several types of targeted therapy that focus on the inner parts
of the cells. Other targeted therapies target receptors that are on
the outside of the cell. Antiangiogenesis inhibitors target the
blood vessels that supply oxygen to the cells, ultimately causing the cells to starve.
Afinitor is an inhibitor of mTOR. mTOR inibition
blocks the translation of genes that regulate cancer cell proliferation. It
also results in reduced levels of certain cell growth factors involved in the development
of new blood vessels, such as vascular endothelial growth factor (VEGF).
Research continues to identify which cancers may be best treated with targeted
therapies and to identify additional targets for more types of cancer.
