It is important to be aware of the fact that laryngeal cancer is unique and
treatment cannot be considered standardized. Treatment options have evolved so
much in the last half century that the physicians and patients now have multiple
choices available to them. Many factors influence the type of treatment options
available to an individual and they must be recognized before any type of
treatment is considered. These factors include age, quality-of-life issues, and
voice results to name a few.
Treatment options for laryngeal cancer involve radiation, chemotherapy,
surgery or a combination of the three. The following descriptions are
deliberately brief and are meant only to present basic information.
A small tumor (what would be called aT1 in the staging system) can be treated
with radiation therapy or with surgery. The most conservative treatment is
radiation only. Radiation is a daily procedure, which lasts about 20 minutes
each day, 5 days a week, for roughly a month and a half. Surgery on the other
hand is done most often through the mouth and involves removing a portion of the
larynx that contains the tumor.
Surgery is a treatment for laryngeal cancer varies considerably according to
the size and extent of the tumor (again based on the staging system). For T4
lesions many surgeons resort to a total laryngectomy, which is the most
aggressive surgical treatment and involves removal of the entire larynx.
For smaller tumors (T1, T2, and T3) there are surgical procedures that do not
involves removal of the entire larynx, rather only a portion in the involved
larynx. Some of the procedures categorized as partial laryngectomies are listed
below:
Partial Cordectomy
This procedure encompasses excision of only the involved portion of the
actual vocal cord.
Total Cordectomy
This procedure involves the excision of both vocal cords with the exception
of any surrounding cartilaginous (bony) structure.
Hemilaryngectomy
This procedure involves the removal of half of the larynx
and is done vertically to include both the vocal cord itself as well as the
cartilaginous structures on the involved side.
Surgical options for reconstruction of the larynx after
one of the above treatments are an option. There are also several options for
speech after a total laryngectomy and can be found in the literature.
Chemotherapy and Radiation Therapy
In some cases a combination of chemotherapy and radiation
therapy can be administered first instead of surgery. In this case the patient
is carefully examined after two treatments of chemotherapy and if the treatment
is working and the tumor has shrunk, then additional chemotherapy can continue.
If after two treatments the tumor remains the same size, then surgery must be
considered the primary option to ensure the cancer does not metastasize (spread)
to other parts of the body.
In addition to the larynx the neck regions must also be
treated with radiation or surgery as this type of cancer may spread to other
areas, specifically the lymph nodes.
Close follow-up is extremely important after treatment
for laryngeal cancer, as there is always a chance of recurrence. The risk is
greater is the patient continues to abuse tobacco. The physician will typically
require examinations once a month for a year and then gradually decrease the
frequency of the visits.
It is important to note that these descriptions are a
brief overview. There are many other implications to successful treatment that
can only be discussed with your physician.
