Resumo
Therapeutic modalities for the treatment of oral cancer result in local adverse effects that can cause interruptions of the radiotherapy and consequently to influence in the patient survival. For the reduction and control of the adverse effects, Dental Care Protocol is applied to patients with oral cancer by dental surgeon team before, during and after radiotherapy and chemotherapy.
Objective: The aim of this study was to investigate the adhesion of patients with oral cancer to a Dental Care Protocol and its Impact in the interruption and survival.
Patients and methods: In this study 133 cases of oral cancer undergoing radiotherapy were selected. The patients were classified according to the period of dental adhesion: no adhesion (group I), adhesion less than or equal to 6 months (group II) and adhesion higher than 6 months (group III). Clinic and pathological aspects, occurrence of interruption of radiotherapy, disease-free survival and overall survival were investigated.
Results: The incidence of radiotherapy interruption due to symptoms was statistically significant in group III compared to group I (p = 0.01). The frequency and duration of interruption due to symptoms were not statistically significant between groups. The conclusion of radiotherapy rate was statistically significant in the group that exceeded 6 months of dental adhesion (p = 0.02). Patient’s survival was higher in group III (p = 0.01) when compared to the other groups.
Conclusion: The adhesion to a dental care protocol did not have any impact on the radiotherapy interruption due to the occurrence of symptoms, however, patients who had higher adhesion to the Dental Care Protocol showed a higher rate of disease-free survival and overall survival.
