Treatment is complex for patients with head and neck (H&N) cancers specific site of disease, stage, pathologic findings guiding treatment decision-making. planning H&N involves a multidisciplinary team experts. This article describes supportive care recommendations in the NCCN Guidelines Head Neck Cancers, as well rationale supporting new section on imaging cancers. also updates to very advanced salivary gland tumors, specifically systemic therapy recommendations.

Head and neck cancers, including those of the lip oral cavity, nasal paranasal sinuses, oropharynx, larynx nasopharynx represent nearly 700,000 new cases 380,000 deaths worldwide per annum, account for over 10,000 annual in United States alone. Improvement outcomes are needed patients with recurrent or metastatic squamous cell carcinoma head (HNSCC). In 2016, US Food Drug Administration (FDA) granted first immunotherapeutic approvals - anti-PD-1 immune checkpoint inhibitors nivolumab...

PURPOSE Death from noncancer causes (competing mortality) is an important event in head and neck cancer, but studies identifying predictors of this are lacking. We sought to identify competing mortality develop a risk stratification model for events. PATIENTS AND METHODS Cohort study 479 patients with stage III IV carcinoma the diagnosed between August 1993 November 2004. Patients were treated on consecutive prospective clinical trials involving organ-preserving chemoradiotherapy surgery....

Reducing radiation treatment dose could improve the quality of life (QOL) patients with good-risk human papillomavirus-associated oropharyngeal squamous cell carcinoma (OPSCC). Whether reduced-dose produces disease control and QOL equivalent to standard chemoradiation is not proven.In this randomized, phase II trial, p16-positive, T1-T2 N1-N2b M0, or T3 N0-N2b M0 OPSCC (7th edition staging) ≤ 10 pack-years smoking received 60 Gy intensity-modulated therapy (IMRT) over 6 weeks concurrent...

Abstract BACKGROUND: Stereotactic body radiotherapy (SBRT) is a technique used to deliver high, ablative doses of radiation in limited number fractions ≥1 extracranial target(s). To the authors' knowledge, prevalence SBRT use among oncologists United States unknown. METHODS: A random sample 1600 American was surveyed via e‐mail and facsimile (fax) regarding usage, including year adoption, motivations, disease sites treated, common prescriptions used. RESULTS: Of 1373 contactable physicians,...

PURPOSE Radiotherapy (RT)/cetuximab (C) demonstrated superiority over RT alone for locally advanced squamous head and neck cancer. We tested this in completely resected, intermediate-risk METHODS Patients had cell carcinoma of the (SCCHN) oral cavity, oropharynx, or larynx, with one more risk factors warranting postoperative RT. were randomly assigned 1:1 to intensity-modulated (60-66 Gy) once-per-week C alone. The primary hypothesis was that + would improve overall survival (OS)...

Objective. Reports have suggested that streptococcal infection may be etiologically related to pediatric autoimmune neuropsychiatric disorders (PANDAS), but there are few good epidemiologic studies support this theory. Using population-based data from a large West-Coast health maintenance organization, we assessed whether was associated with increased risk for obsessive-compulsive disorder (OCD), Tourette's syndrome (TS), or tic disorder.

Intensity-modulated radiation therapy (IMRT) is a novel approach to the planning and delivery of therapy. The prevalence IMRT use among oncologists in U.S. appears be increasing, despite limited data evaluating its risks benefits.A random sample U.S., including cohort 441 physicians who were surveyed 2002, was regarding use. users questioned their frequency use, clinical applications, reasons for adopting IMRT. nonusers asked not using IMRT, whether they planned it future, wanting adopt...
