Mr. T got mucositis today. We were expecting the mouth sores to start. He was very lucky so far. All you can do is follow good hygiene....and use mouth-rinses 4 to 6 times a day. Morphine is used for pain....and nothing else you can do about them. In time...when his counts start to rise...the mouth sores will go away on their own.
Cancer patients undergoing chemotherapy usually become symptomatic four to five days after beginning treatment, reaching a peak at around day 10, and then slowly improving over the course of a few weeks. Mucositis associated with radiotherapy usually appears at the end of the second week of treatment and may last for six to eight weeks.
As a result of cell death in reaction to chemo- or radio-therapy, the mucosal lining of the mouth becomes thin, may slough off and then become red, inflamed and ulcerated. The ulcers may become covered by a yellowish white fibrin clot called a pseudomembrane. Peripheral
erythema is usually present. Ulcers may range from 0.5 cm to greater than 4 cm. Oral mucositis can be severely painful. The degree of pain is usually related to the extent of the tissue damage. Pain is often described as a burning sensation accompanied by reddening. Due to pain, the patient may experience trouble speaking, eating, or even opening the mouth.
Dysgeusia, or an alteration in taste perception, is common, especially for those who are receiving concomitant radiation therapy to the neck and mouth area. "Taste blindness," or an altered sense of taste, is a temporary condition that occurs because of effects on taste buds that are mostly located in the tongue. Sometimes, only partial recovery of taste occurs. Common complaints are of food tasting too sweet or too bitter or of a continuous metallic taste.
[
edit] Diagnosis
Diagnosis is based on the symptoms the patient is experiencing and the appearance of the tissues of the mouth following
chemotherapy,
bone marrow transplants or
radiotherapy. Red burn-like sores or ulcers throughout the mouth is enough to diagnose mucositis.
[
edit] Treatment
Treatment of mucositis is mainly supportive.
Oral hygiene is the mainstay of treatment; patients are encouraged to clean their mouth every four hours and at bedtime, more often if the mucositis becomes worse. Water-soluble jellies can be used to lubricate the mouth. Salt mouthwash can soothe the pain and keep food particles clear so as to avoid infection. Patients are also encouraged to drink plenty of liquids, at least three liters a day, and avoid alcohol. Citrus fruits, alcohol, and foods that are hot are all known to aggravate mucositis lesions. Medicinal mouthwashes may be used such as Chlorhexidine gluconate and viscous Lidocain for relief of pain. Palifermin, brand name "Kepivance", is a human KGF (keratinocyte growth factor) that has shown to enhance epithelial cell proliferation, differentiation, and migration. Experimental therapies have been reported, including the use of cytokines and other modifiers of
inflammation (eg, IL-1, IL-11, TGF-beta3),
amino acid supplementation (eg, glutamine),
vitamins, colony-stimulating factors,
cryotherapy, and laser therapy. Symptomatic relief of the pain of oral mucositis is provided by barrier protection agents such as "Gelclair." This viscous oral gel can be diluted and used as an oral rinse. The film forming agents within Gelclair coat the oral mucosa shielding ulcerated tissues and protecting exposed nerve endings.

edit] Complications
Sores or ulcerations can become infected by
virus,
bacteria or
fungus. Pain and loss of taste perception makes it more difficult to eat, which leads to weight loss. Ulcers may act as a site for local infection and a portal of entry for oral flora that, in some instances, may cause septicemia (especially in immunosuppressed patients). Approximately half of all patients who receive chemotherapy develop such severe OM that it becomes dose-limiting such that the patient's cancer treatment must be modified, compromising the prognosis.
