These NCCN Guidelines Insights focus on nutrition and supportive care for patients with head and neck cancers. This topic was a recent addition to the NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Head and Neck Cancers. The NCCN Guidelines Insights focus on major updates to the NCCN Guidelines and discuss the new updates in greater detail. The complete version of the NCCN Guidelines for Head and Neck Cancers is available on the NCCN Web site (NCCN.org).

This selection from the NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Head and Neck Cancers focuses on glottic laryngeal cancer, which is the most common type of laryngeal cancer and has an excellent cure rate. The lymphatic drainage of the glottis is sparse, and early stage primaries rarely spread to regional nodes. Because hoarseness is an early symptom, most glottic laryngeal cancer is early stage at diagnosis. Updates to these guidelines for 2014 include revisions to “Principles of Radiation Therapy” for each site and “Principles of Surgery,” and the addition of a new section on “Principles of Dental Evaluation and Management.”

These NCCN Guidelines Insights focus on recent updates to the 2015 NCCN Guidelines for Head and Neck (H&N) Cancers. These Insights describe the different types of particle therapy that may be used to treat H&N cancers, in contrast to traditional radiation therapy (RT) with photons (x-ray). Research is ongoing regarding the different types of particle therapy, including protons and carbon ions, with the goals of reducing the long-term side effects from RT and improving the therapeutic index. For the 2015 update, the NCCN H&N Cancers Panel agreed to delete recommendations for neutron therapy for salivary gland cancers, because of its limited availability, which has decreased over the past 2 decades; the small number of patients in the United States who currently receive this treatment; and concerns that the toxicity of neutron therapy may offset potential disease control advantages.

Identifying individuals with hereditary syndromes allows for timely cancer surveillance, opportunities for risk reduction, and syndrome-specific management. Establishing criteria for hereditary cancer risk assessment allows for the identification of individuals who are carriers of pathogenic genetic variants. The NCCN Guidelines for Genetic/Familial High-Risk Assessment: Colorectal provides recommendations for the assessment and management of patients at risk for or diagnosed with high-risk colorectal cancer syndromes. The NCCN Genetic/Familial High-Risk Assessment: Colorectal panel meets annually to evaluate and update their recommendations based on their clinical expertise and new scientific data. These NCCN Guidelines Insights focus on familial adenomatous polyposis (FAP)/attenuated familial adenomatous polyposis (AFAP) syndrome and considerations for management of duodenal neoplasia.
