There is always research going on in the area of nasal cavity
and paranasal sinus cancers. Scientists are looking for causes and ways
to prevent nasal cavity and paranasal sinus cancers. Research on better
treatment for nasal cavity and paranasal sinus cancer is now being done
at many medical centers, university hospitals, and other institutions
across the nation. Doctors and patients are urged to contact the
nearest cancer center to find out what clinical trials are going on in
their community.
Genetics
We don't know of any inherited tendencies for nasal cavity and
paranasal sinus cancer, but scientists are discovering changes in the
genes in these cancers that occur during the patient's lifetime. These
changes are what transform normal cells into cancer cells.
Understanding these genetic changes will help doctors develop
better methods of diagnosing this disease as well as treatments that
are more effective and have fewer side effects than ones currently
available.
For example, researchers have found that many head and neck
cancers have mutations (genetic changes) of the p53 tumor suppressor
gene. These changes lead to additional mutations of other genes, which
make the cells better able to grow and spread. Scientists are studying
several gene therapies that target this gene.
Viral infections
Researchers have found signs that infection with the human
papilloma virus (HPV) may be part of the cause of some head and neck
cancers. So far, there is no evidence that HPV infection contributes to
cancers of the nose or sinuses.
Immunotherapy
Doctors are learning how to make the immune system of patients
reacts against their cancers. For example, researchers are testing the
effectiveness of immunotherapy that stimulates immune system cells to
destroy cancer cells that contain certain substances. Because nasal
cavity and paranasal sinus cancers are rare, this approach has not yet
been tested much for these tumors. As new tumor antigens (substances
that stimulate an immune response) are discovered and new ways to
stimulate the immune system are developed, immunotherapy may assume a
more prominent role in treating people with nasal cavity and paranasal
sinus cancer.
Radiation therapy
Clinical trials currently in progress are studying ways to
make radiation therapy more effective by using radiosensitizers. These
drugs make cancer cells more sensitive to radiation therapy. Other
studies are testing radioprotective agents. These drugs protect normal
cells from damage by radiation and thereby reduce side effects of
radiation therapy. Reducing side effects improves patients’
quality of life as well as helping them tolerate higher radiation doses
that can kill more cancer cells.
