Chemotherapy is treatment with anti-cancer drugs that are
given into a vein (IV) or by mouth. These drugs enter the bloodstream
and reach all areas of the body, making this treatment useful for
cancers that have spread beyond the head and neck. Some chemotherapy
drugs also make cancer cells more vulnerable to radiation. Chemotherapy
is often used together with radiation therapy as the first treatment
for more advanced stages of this cancer. It is also used alone for
patients whose NPC has spread to distant organs such as the lungs,
bones, or liver.
Doctors give chemotherapy in cycles, with each period of
treatment followed by a rest period to allow the body time to recover.
Chemotherapy cycles generally last about 3 to 4 weeks. Chemotherapy is
often not recommended for patients in poor health, but advanced age by
itself is not a barrier to getting chemotherapy.
Here is a list of the drugs most often used to treat NPC. In
most cases, combinations of 2 or more of these drugs are used.
- cisplatin
- carboplatin
- 5-fluorouracil (5-FU)
- bleomycin
- methotrexate
- doxorubicin
- epirubicin
- paclitaxel
- docetaxel
- gemcitabine
Possible side effects of chemotherapy
Chemotherapy drugs work by attacking cells that are dividing
quickly, which is why they work against cancer cells. But other cells
in the body, such as those in the bone marrow, the lining of the mouth
and intestines, and the hair follicles, also divide quickly. These
cells are also likely to be affected by chemotherapy, which can lead to
side effects.
The side effects of chemotherapy depend on the type and dose
of drugs you are given and how long they are taken. These side effects
can include:
- hair loss
- mouth sores
- loss of appetite
- nausea and vomiting
- increased chance of infections (due to low white blood cell
counts)
- easy bruising or bleeding (due to low blood platelet
counts)
- fatigue (due to low red blood cell counts)
These side effects are usually short-term and go away after
treatment is finished. There are often ways to lessen these side
effects. For example, there are drugs that can be given to help prevent
or reduce nausea and vomiting. Be sure to ask your doctor or nurse
about medicines to help reduce side effects, and let him or her know
when you do have side effects so they can be managed effectively.
Some drugs can have other side effects. For example, cisplatin
can damage nerves. This can sometimes lead to hearing loss or symptoms
in the hands and feet such as pain, burning or tingling sensations,
sensitivity to cold or heat, or weakness. (This is called peripheral
neuropathy.) In most cases this goes away once treatment is stopped,
but it may last a long time in some people. You should report this, as
well as any other side effects or changes you notice while getting
chemotherapy to your medical team so that you can get prompt treatment
for them. In some cases, the doses of the chemotherapy drugs may need
to be reduced or treatment may need to be delayed or stopped to prevent
the effects from getting worse.
