Oral Cavity
With early detection and immediate treatment,
survival rates can be dramatically improved. For lip and oral cancer,
if detected at its early stages, almost 80% of the patients survive
five years or more. However, when diagnosed at the advanced stages,
the five year survival rate drops to a mere 18%.
Nose and sinuses
Cancers of the nasal cavity often go undetected
until they reach an advanced stage. If diagnosed at the early stages,
the five-year survival rates are 60-70%. However, if cancers are
more advanced, only 10-30% of the patients survive five years or
more.
Oropharynx
In cancer of the oropharynx, 60-80% of the
patients survive five years or more if the cancer is detected in the
early stages. As the cancer advances, the survival rate drops to
15-30%.
Nasopharynx
Patients who are diagnosed with early stage
cancers that have originated in the nasopharynx have an excellent
chance of a complete cure (almost 95%). Unfortunately, most of the
time, the patients are in an advanced stage at the time of initial
diagnosis. With the new chemotherapy drugs, the five year survival
rate has improved and 5-40% of the patients survive five years or
longer.
Larynx
Small cancers of the larynx have an excellent
five-year survival rate of 75-95%. However, as with most of the head
and neck cancers, the survival rates drop dramatically as the cancer
advances. Only 15-25% of the patients survive five years or more
after being initially diagnosed with advanced laryngeal cancer.
