ObjectiveTo evaluate the epidemiological profile and survival rate of oral and oropharyngeal cancer patients seen at a university hospital.MethodsA cross-sectional study was carried out by means of the pathological reports of patients with oral and oropharyngeal cancer, seen at a university hospital of the Southern Region, between January 2004 and December 2014. Information was collected on patients and tumors. The mortality rate was gathered from the patient death registry in the Mortality Information System. Data were analyzed using the Kaplan-Meier survival curve and the log-rank test to compare variables.ResultsThe 5- and 10-year survival rates were 42% and 38%, respectively. The anatomical location had a significant association with survival rate (p=0.001), with the rates were better in the lips (p=0.04), and worse in the oropharynx (p=0.03). There were no statistically significant differences between survival rates according to age, sex, ethnicity, schooling level and histologic grade.ConclusionThe survival rates of oral and oropharyngeal cancer were and associated with the anatomical site of the tumor.
ResumoOs Bifosfonatos (BFS) são fármacos antirreabsortivos frequentemente utilizados no tratamento de desordens ósseas e de neoplasias malignas metastáticas. Seu mecanismo de ação consiste na inibição da atividade osteoclástica e angiogênica do tecido ósseo. No entanto, o uso crônico desses medicamentos pode desenvolver a osteonecrose dos maxilares associada aos bifosfonatos (OMAB), principalmente em pacientes submetidos a traumas prévios. O presente trabalho objetiva revisar abordagens terapêuticas para esses pacientes, focando na prevenção e tratamento dessas patologias. A literatura tem apresentado propostas variadas para o tratamento da OMAB, muitas vezes controverso. O tratamento dessas patologias tem se tornado desafiador, uma vez que os protocolos nem sempre são eficientes para controlar tal condição. Assim, previamente à terapêutica com BFS, os profissionais de saúde devem realizar todos os procedimentos necessários para adequação do meio bucal dos pacientes, bem como manter um rigoroso acompanhamento da sua condição bucal. Diante disso, é de fundamental importância a ação multidisciplinar entre médicos e cirurgiões-dentistas no manejo desses pacientes. Descritores: Odontologia. Difosfonatos. Mandíbula. Maxila.
