Clinical practice guideline of the Spanish society of oral surgery for dental care in patients with oral cancer.

Background: Oral cancer is the sixteenth most common malignant neoplasm worldwide, with a high mortality rate, greater than 50% at five years, and high morbidity. The effect of oncological treatment in the oral cavity is broad and has multiple levels, therefore knowing these effects and preventing them is essential for avoiding an increase in the oral pathology related with oncological therapy, maintaining the quality of life of the patient, and improving the efficacy of the treatment itself.

Material and methods: A group of experts belonging to the fields of Dentistry, Maxillofacial Surgery and Oncology of the University of Seville and the Virgen del Rocío University Hospital of Seville in collaboration with the University of Valencia, University of Barcelona, and University of the Basque Country, developed this Clinical Practice Guideline for the proper clinical management of patients diagnosed with oral cancer. The clinical questions were formulated in PICO format. The databases consulted were Medline/PubMed and Embase/Elsevier. The systematic reviews published on the topic were identified on Tripdatabase, Cochrane Library and CRD (Centre for Reviews and Dissemination). The recommendations were prepared based on the GRADE methodology.

Results: Various recommendations were defined, derived from the 21 PICO questions, referring to prevention, treatment and care for alterations arising from the pathology of oral cancer itself and its treatment.

Conclusions: The preparation of this clinical practice guideline allows recommendations to be generated based on the scientific evidence available, on dentistry actions in patients with oral cancer and undergoing oncological treatment, which may be of use to the multidisciplinary team treating this type of patient.
