Laryngeal cancers
Stage 0
This stage is highly curable with either stripping to
surgically remove the abnormal layer of cells or vaporizing the
abnormal cell layer with a laser beam. The patient is then watched
closely to see if the cancer returns.
If the cancer comes back, radiation will be used. Between 96%
and 100% of patients at this stage will not need extensive surgery. It
is important for these patients to realize that continuing to smoke
increases the risk that a new cancer will develop.
Stages I and II laryngeal cancers
Most patients with stage I and II laryngeal cancer can be
successfully treated without totally removing their larynx. Radiation
alone (without surgery) is successful in treating 80% to 90% of
patients with stage I laryngeal cancer and 70% to 80% of stage II
patients.
Partial laryngectomy may also be used with similar survival
results. However, voice results tend to be better with radiation
therapy than with partial laryngectomy, and the complication rate for
surgery tends to be greater than for radiation treatment alone. Many
doctors choose to use radiation therapy for smaller cancers, only using
surgery for cancers that come back after treatment. In either case, the
treatment not chosen at first may be used later if initial treatment
fails.
Selected superficial glottic cancers may be treated by
removing the cancerous vocal cord, or even by laser excision.
Supraglottic cancers tend to spread to the neck lymph nodes.
If you are having surgery for your tumor, then the surgeon will also
likely remove lymph nodes from your neck. If your treatment is to be
radiation therapy, you will also receive radiation therapy to your
neck.
Stages III and IV laryngeal cancers
Stages III and IV laryngeal cancers generally require combined
therapy of either surgery and radiation, or radiation and chemotherapy,
or all 3 types of treatment. Surgical treatment of these tumors almost
always requires complete removal of the larynx, although a small group
of T3 laryngeal cancers may still be treated by partial laryngectomy.
More advanced stage cancers have a higher risk for spread to
nearby lymph nodes. These lymph nodes are often removed along with the
tumor if surgery is being used to treat the cancer. Radiation therapy,
often given with chemo, may be required after surgery, particularly if
there is lymph node metastasis.
Instead of using surgery as the first step, many doctors now
prefer to start treatment with radiation and chemotherapy. Surgery can
then be done to remove any remaining cancer. This approach works as
well as surgery alone to treat the cancer, but it gives the patient the
chance to save the larynx. If the framework of the larynx (such as the
thyroid cartilage) has been destroyed by the cancer, the larynx may
never work normally again – no matter what treatment is
chosen. In these cases, surgery to remove the larynx may be the best
treatment approach.
Cancers that are too large to be completely removed by surgery
are often treated with radiation, usually combined with chemotherapy.
Several studies continue to look at various methods of combined
radiation and chemotherapy to improve outcomes and reduce the need for
radical resection of advanced laryngeal cancer.
Hypopharyngeal cancers
These are more difficult to treat than laryngeal cancers.
Because they do not cause symptoms early, most are diagnosed in an
advanced stage. Tumors in this region have a high likelihood of lymph
node metastasis, even when there is no obvious mass in the neck.
Because of this risk, radiation therapy of the neck is recommended for
patients who have had their hypopharyngeal cancer removed by surgery.
Stages I and II hypopharyngeal cancers
The 2 main options for treating small tumors are radiation and
surgery. Larger tumors are treated with surgery.
Surgery would include removing all or part of the pharynx and
lymph nodes in the neck. The larynx is sometimes removed as well.
Patients who have a high chance of the cancer returning (based on the
what is found during surgery) may then be treated with radiation or
chemoradiation.
Patients who receive radiation as their main treatment will be
assessed after the treatment is complete. If there is still cancer in
the hypopharynx, surgery will be done.
Stages III and IV hypopharyngeal cancers
These can be treated with extensive surgery followed by
radiation alone or chemoradiation. Another choice is to give
chemotherapy as the first treatment. If the cancer goes away with
chemo, radiation therapy is given. Lymph nodes in the neck may be
removed after radiation. If the tumor shrinks without going away, the
patient may receive chemoradiation or treatment with surgery. Further
treatment depends upon the results of the prior therapy.
Recurrent laryngeal and hypopharyngeal
cancers
Cancer is called recurrent when it come backs after treatment.
Recurrence can be local (in or near the same place it started) or
distant (spread to organs such as the lungs or bone). Treatment options
for patients whose laryngeal or hypopharyngeal cancers come back after
treatment depend on what their initial treatment was and on the
location of the recurrent cancer (local recurrence or distant
recurrence).
Local recurrences in patients who have already had partial
laryngectomy can be treated with total laryngectomy or with radiation
therapy. If your cancer comes back locally after radiation therapy, the
usual treatment is total laryngectomy, but additional radiation therapy
is sometimes used. Chemotherapy (perhaps in a clinical trial) is the
usual treatment for distant recurrences and for local recurrences that
have not responded to combined radiation therapy and surgery.
