Squamous cell carcinoma of the oral cavity, oropharynx, and larynx: a scoping review of treatment guidelines worldwide

Worldwide incidence and mortality of head and neck cancer remain at high rates. Treatment protocols include surgery, chemotherapy, radiotherapy, and immunotherapy, being associated or combined according to the clinical condition of each patient. Clinical guidelines are needed to guide treatment decisions, based on the clinicopathological characteristics of the disease, the functional considerations, and patient preferences. The aim of this scoping review was to identify, describe, and compare the available evidence concerning worldwide protocols and treatment guidelines for oral cavity, oropharynx, and larynx cancer. It is expected to identify the current treatment guidelines for oral cavity, oropharynx, and larynx cancer, as well as the societies, authors or countries that adopt them. Additionally, we expected to know if there are differences in protocol recommendations according to each clinicopathological characteristics.
