Title in Portuguese
Ocorrência e grau de severidade da mucosite bucal em relação ao fluxo salivar de pacientes sob quimioterapia
Keywords in Portuguese
Mucosa bucal
Mucosite
Quimioterapia
Saliva
Abstract in Portuguese
A mucosite induzida por quimioterapia e radioterapia representa um dos principais efeitos colaterais indesejáveis no tratamento do câncer. A dor associada à mucosite, dificulta a mastigação, a deglutição e freqüentemente é causa de interrupção temporária do tratamento e de atraso na recuperação do paciente. Ela se manifesta por eritema generalizado e/ou lesões ulcerativas na mucosa bucal, laringe e no trato gastrointestinal. O grupo estudado foi composto por 33 pacientes com câncer de cólon com idades entre 28 e 66 anos, 15 mulheres e 18 homens. Noventa e nove ciclos de quimioterapia foram analisados. O esquema de tratamento utilizado foi uma combinação da droga antineoplásica 5-fluorouracil, com o agente modulador ácido folínico. Idade, gênero, fluxo salivar antes e durante o tratamento foram associados à ocorrência de mucosite OMAS e mucosite WHO, tanto para pacientes com fluxo salivar normal quanto para pacientes com fluxo salivar reduzido. Também foram analisados os sítios de maior ocorrência das lesões e o tamanho das lesões em relação aos fluxos normais e reduzidos. A partir dessas associações obtivemos os seguintes resultados: os pacientes com fluxo salivar reduzido antes e durante a quimioterapia desenvolveram mais mucosite OMAS e WHO em comparação com os pacientes com fluxo normal. Os pacientes com fluxo salivar reduzido tiveram mais ulceração, considerando qualquer tamanho de lesão. A semimucosa do lábio inferior e as bordas laterais de língua foram os sítios em que ocorreram a maior incidência de ulceração e as úlceras de maior severidade.

Abstract in English
Mucositis induced by chemotherapy and radiotherapy represents one of most undesirable side effects in the cancer treatment. The pain associated to mucositis raise difficulties to patients ability to chew and swallow and frequently causes temporary interruption of treatment and delay in patient recovery. It presents itself as redness and/or ulcerative sores in the soft tissues of the mouth, throat and gastrointestinal tract. The studied group was composed by 33 patients with colon cancer with ages between 28 and 66 years, 15 women and 18 men Ninety nine cycles of chemotherapy were analyzed. A combination of 5-fluorouracil, with folinic acid was used. Age, gender, salivary flow before and during treatment were associated to the occurrence of OMAS and WHO mucositis for patients with normal and reduced salivary flow. Size and sites of ulceration occurrence were also analyzed. The following results were found: the patients with reduction of salivary flow, before and during chemotherapy developed more OMAS and Who mucositis comparing to normal flow patients. Patients with reduced flow also had more ulceration and the mucosal surfaces of inferior lips and the lateral borders of tongue were the sites with more severe ulceration rates.
