Oral
side effects that can result from cancer treatments include
oral mucositis, oral thrush
and loss of taste sensation or smell.
Oral health is
important!
In addition to being painful, a sore mouth can become easily
infected. Every step should be taken to prevent infections, because
they can be hard to fight during chemotherapy and can lead to
serious problems or the interruption of your treatment.
Prevention:
Talk you your doctor about seeing a dentist at least two weeks
before chemotherapy begins. If you've already started
chemotherapy and didn’t go to a dentist, see one as soon as
possible, and notify him
or her that you are receiving treatment.
Tip: If
brushing becomes too painful due to mouth sores, try a finger
toothbrush. Meant for babies, they are very gentle yet are
helpful in keeping the teeth and gums clean. They can be found in
most drugstores and grocery stores.

Oral
Mucositis ( stomatitis)
Inflammation of the mucous
membranes in the mouth.
It can range from redness to severe ulceration.
This is a side effect associated with many cancer treatments.

Mucositis is painful and can affect nutrition,
increase risk of infection, and can delay treatment. It can lead to
major complications after or during cancer treatment.

A prospective, randomized study of cryotherapy ... [ice chips
and ice-cold water shortly before, during, and for additional 90
min after completion of treatment] ... during administration
of high-dose melphalan to decrease the severity and duration of
oral mucositis in patients with multiple myeloma undergoing
autologous peripheral blood stem cell transplantation. Bone
Marrow Transplant. 2006 Jun;37(11):1031-5. PMID: 16633359
Compared to the normal saline group, patients using cryotherapy
experienced less grade 3-4
mucositis, 14 vs 74%, P=0.0005. Patients receiving cryotherapy
also had statistically
lower uses of narcotics and TPN, although there were no
differences in length of
hospitalization or weight loss. Patient-reported pain was
significantly lower and
activities were significantly better in the cryotherapy group.

News (Medscape):
"Ascorbic acid has antioxidant properties and participates in wound healing.
Dehydroascorbic acid (DHA) is a prodrug form of ascorbic acid that readily crosses cell
membranes and is converted into ascorbic acid within mucosal cells.
The hamster model of acute radiation is useful for assessing treatment for mucositis.
There is little systemic toxicity in the model, in which hamsters receive radiation therapy
to the buccal mucosa. In a randomized study[4] comparing DHA given topically vs a
non-DHA-containing topical solution in terms of their ability to reduce the incidence of
mucosal damage, DHA therapy led to no change in the onset of acute mucositis.
Other studies are now under way to evaluate other doses of DHA in this model.
This compound is being formulated for use in human studies, which are expected
to begin within the next 6 to 12 months. Interestingly, ascorbic acid does not
seem to be effective in this model, perhaps because it does not enter into cells as efficiently.

Oral thrush
presents as distinctive
lesions of the mouth, tongue, or cheeks -- caused
by infection of the mouth with the fungus (yeast) Candida albicans..
Lesions are easily brushed away revealing a reddened, tender area that
may bleed slightly." MedlinePlus

Loss of taste sensation is called
Ageusia.
Anosmia is
the technical name for loss of smell. These are expected side effect
of localized radiation treatment, which can improve with time. These
effects can have " devastating physical and psychological consequences for the patient. Oral complications include
xerostomia, dental decay, mucositis, taste loss,
osteoradionecrosis, infection, and trismus. In many instances, these
problems can be eradicated or controlled with appropriate
treatment."
"As the
effects of the treatment fade away things return to normal, but it
may take up to a year for your sense of taste to return."
source cancerbacup.org.uk
Consulting a nutritionally oriented
health professional is advised to determine nutritional deficiencies
that may contribute to the problem, as well as nutrients that might
help to rebuild the cells damaged by treatment, such as Zinc,
and vitamin B-12, glutamine.

 | Information from Merck
Manual
"Depending on the cause of the taste disorder, a doctor may
recommend changing or stopping
a suspected drug, keeping the mouth
wet by sucking on candy, or just waiting several weeks
to see if
the problem disappears. Zinc supplements, which can be purchased
without a
prescription, are claimed to speed recovery, especially
from taste disorders that follow
a bout of the flu. The effect,
however, has not been scientifically confirmed."

"The cells comprising taste buds usually
will regenerate
within four months after treatment. However, the degree of
long-term
impairment of taste is quite variable from patient to
patient."
