Treatment Overview
Surgical removal (excision) of the affected skin is the
most effective treatment for
melanoma. Excision involves removing the entire
melanoma along with a border (margin) of normal-appearing skin. Additional
treatment may be needed based on the
stage of the melanoma.
Staging for treatment of melanoma
Staging is a method of describing how far a cancer has
progressed. It is done after excision of the melanoma and assessment of lymph
nodes and other parts of the body to determine whether the cancer has spread.
Staging helps doctors determine the best possible treatment. Staging
evaluates:6
- Tumor thickness and depth.
- Ulceration of skin over the melanoma.
Initial treatment
Melanoma may be cured if caught and treated in its early stages
when it affects only the skin. If melanoma is confined to the skin (primary
melanoma), you will have surgery to remove the affected skin. If the
melanoma is thin and has not invaded surrounding tissues, excision may cure the
melanoma. In more advanced stages, melanoma may spread, or metastasize, to
other organs and bones, making cure less likely.
Initial treatment will depend on the stage of the
melanoma.8, 9
- Stage 0 melanoma or melanoma in situ invades
only the outer layer of skin. Surgery to remove the lesion or
mole is usually all that is needed.
- Stage
I melanoma is generally less than
1 mm (0.04 in.) thick. Surgery
to remove the cancer is usually all that is needed. Some advanced stage I
melanomas may be treated like stage II.
- Stage II melanoma is more
than 1 mm (0.04 in.) thick, but
does not spread to the
lymph nodes. Surgery to remove the cancer is most
common. Other treatments your doctor may consider are a
lymph node biopsy, a medicine called
interferon, observation, or enrolling you in a
clinical trial. Reconstructive surgery may be needed
to repair the scar left by surgery, especially if it is on the face or hands.
Some advanced stage II melanomas may be treated like stage
III.
- Stage III melanoma has spread to the lymph nodes. Treatment
includes surgery to remove the primary melanoma and all of the
lymph nodes near the primary melanoma. This is usually
followed by
immunotherapy with interferon. Interferon is a protein
similar to proteins made by the white blood cells. These proteins act in two
ways—by weakening or killing cancer cells and also by boosting the body's
immune system to fight the cancer. Your doctor may also talk to you about
enrollment in a clinical trial.
- Stage IV melanoma is cancer that
has spread far from the initial cancer site, perhaps to the liver, brain, or
bones. Treatment may include surgery,
radiation,
chemotherapy, or
immunotherapy with drugs such as interferon. Most
treatment in stage IV is to treat the symptoms caused when the cancer spreads
to other areas, such as bone pain if the cancer spreads to the bone.
Treatment for melanoma that develops in other places in the body
depends on the site. Sites can include:
- The eye (ocular melanoma). In the past,
melanoma of the eye often required removal of the eyeball (enucleation).
Sometimes it is still necessary to remove the eye, but there are now
alternative treatments for some of these cases. Treatment may include
radiation, laser treatment called photocoagulation to seal off the blood supply
to the cancer, and surgeries that do not remove the entire eyeball.10
- The skin of a finger or toe or under a nail.
Melanoma in these sites is treated by removing (excising) diseased tissue.
Often the entire finger or toe will have to be removed.3
Ongoing treatment
Regular follow-up appointments are important once you have been
diagnosed with melanoma.11 After surgery to remove
melanoma, you will have follow-up appointments every 3 to 6 months for 5 years,
then annually. You will continue to have follow-up appointments every 3 to 6
months if you have:
Treatment if the condition gets worse
Swollen or tender lymph nodes may be a sign that the melanoma has
spread. Any enlarged regional lymph nodes should be removed and checked for
melanoma.
Stage IV (metastatic) melanoma responds poorly to most
forms of treatment. The 5-year survival rate for stage IV melanoma is less than
50%.11 The goal of treatment of metastatic melanoma is
to control symptoms, reduce complications, and increase comfort (palliative care). It is not intended to cure the
disease. Metastatic melanoma may be treated with:
- Surgery.
- Radiation
therapy.
- Chemotherapy with dacarbazine (DTIC).
The main side effect from DTIC is nausea and vomiting, which usually can be
controlled with antinausea medicines. Another drug called temozolomide is being
studied for treating melanoma. Temozolomide may be used to treat cancer that
has spread (metastasized) to the brain.
- Immunotherapy
with drugs such as interferon.
If you have metastatic melanoma, you may wish to participate in
a clinical trial. Check with your doctor to determine
whether clinical trials are available in your area.
What To Think About
After removal of a primary melanoma, a skin
graft or other reconstructive surgery may be needed
for cosmetic reasons or to restore function. This is most likely if the
melanoma was large or was a late-stage tumor.
Melanoma can come back after treatment. Learn to do a
skin
self-exam and to check for swelling in your lymph nodes, and report any
changes to your health professional.11 It's a good idea
to get in the habit of doing this skin and lymph-node check at the same time
every month.
There is no "normal" or "right" way to react to a diagnosis of
cancer. There are many steps you can take to help with your
emotional reaction to cancer. If your reaction
interferes with your ability to make decisions about your health, it is
important to talk with your doctor. Your cancer treatment center may offer
psychological or financial services. You may also contact your local chapter of
the American Cancer Society to help you find a support group. Talking with
other people who may have had similar feelings can be very helpful.
End-of-life issues
If you have advanced (metastatic) melanoma, you may choose to
stop curative treatment and focus on care that assures your comfort (palliative care). Making the decision about when to
stop medical treatment aimed at prolonging life and shift the focus to
palliative care is difficult. For more information, see the following
