Purpose To update the guideline recommendations on the use of larynx-preservation strategies in the treatment of laryngeal cancer. Methods An Expert Panel updated the systematic review of the literature for the period from January 2005 to May 2017. Results The panel confirmed that the use of a larynx-preservation approach for appropriately selected patients does not compromise survival. No larynx-preservation approach offered a survival advantage compared with total laryngectomy and adjuvant therapy as indicated...

PURPOSE: Few studies have reported large inter-observer variations in target volume selection and delineation in patients treated with radiotherapy for head and neck squamous cell carcinoma. Consensus guidelines have been published for the neck nodes (see Grégoire et al., 2003, 2014), but such recommendations are lacking for primary tumour delineation. For the latter, two main schools of thoughts are prevailing, one based on geometric expansion of the Gross Tumour Volume (GTV) as promoted by DAHANCA, and the other one based on anatomical expansion of the GTV using compartmentalization of head and neck anatomy...

BACKGROUND: The aim of this study was to report outcomes and late toxicity following hypofractionated accelerated radiotherapy for T2 glottic cancers. We highlight the importance of hypofractionated treatments with shorter overall treatment times, in improving outcomes for T2 glottic cancers. We also compare the biologically effective dose of hypofractionated regimes, with conventional fractionation. METHODS: One hundred twelve patients with T2 glottic cancer were treated between January 1999 and December 2005...

Distinguishing between distantly metastatic and metachronous lung primary carcinoma is challenging for patients with a history of head and neck cancer. There are implications for registry data, prognosis and related counseling, and management options, including eligibility for precision oncology trials. Patients with human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma who were treated under a uniform clinical protocol and achieved a complete response were identified in a single-institution prospective head and neck cancer epidemiology database (n = 205)...

Farzan Siddiqui, Benjamin Movsas
Head and neck cancers account for approximately 3% of all cancers in the United States with 62,000 new cases diagnosed annually. The global incidence is approximately 700,000 new cases a year. There has also been a recent increase in human papilloma virus-related oropharyngeal cancers. External beam radiation therapy (RT) is commonly used as an effective therapy for head and neck (H&N) cancers. This is used as a definitive treatment (alone or in combination with chemotherapy) or as an adjuvant treatment after surgical resection of the tumors...

Patients undergoing radiation therapy for the head and neck are susceptible to a significant and often abrupt deterioration in their oral health. The oral morbidities of radiation therapy include but are not limited to an increased susceptibility to dental caries and periodontal disease. They also include profound and often permanent functional and sensory changes involving the oral soft tissue. These changes range from oral mucositis experienced during and soon after treatment, mucosal opportunistic infections, neurosensory disorders, and tissue fibrosis...

PURPOSE: To investigate whether reducing the target volume of intensity-modulated radiotherapy (IMRT) after induction chemotherapy (IC) improves the quality of life (QOL) in locoregionally advanced nasopharyngeal carcinoma (NPC) without decreasing the local control and survival rate. PATIENTS AND METHODS: A total number of 212 NPC patients staged as III-IVb were randomly assigned to group A (n=97) or group B (n=115) in this prospective clinical trial. All patients received IC followed by cisplatin concurrent with IMRT...

BACKGROUND: The role of image-guided surveillance as compared with planned neck dissection in the treatment of patients with squamous-cell carcinoma of the head and neck who have advanced nodal disease (stage N2 or N3) and who have received chemoradiotherapy for primary treatment is a matter of debate. METHODS: In this prospective, randomized, controlled trial, we assessed the noninferiority of positron-emission tomography-computed tomography (PET-CT)-guided surveillance (performed 12 weeks after the end of chemoradiotherapy, with neck dissection performed only if PET-CT showed an incomplete or equivocal response) to planned neck dissection in patients with stage N2 or N3 disease...

Purpose The role of adjuvant chemotherapy (AC) or induction chemotherapy (IC) in the treatment of locally advanced nasopharyngeal carcinoma is controversial. The individual patient data from the Meta-Analysis of Chemotherapy in Nasopharynx Carcinoma database were used to compare all available treatments. Methods All randomized trials of radiotherapy (RT) with or without chemotherapy in nonmetastatic nasopharyngeal carcinoma were considered. Overall, 20 trials and 5,144 patients were included. Treatments were grouped into seven categories: RT alone (RT), IC followed by RT (IC-RT), RT followed by AC (RT-AC), IC followed by RT followed by AC (IC-RT-AC), concomitant chemoradiotherapy (CRT), IC followed by CRT (IC-CRT), and CRT followed by AC (CRT-AC)...

BACKGROUND: Due to unique biology and prognosis, precise identification of predictive parameters is critical for p16+ oropharyngeal squamous cell carcinoma (OPSCC). Prior studies showing absence of prognostication from extracapsular spread (ECS) and/or high N-classification in surgically-treated p16+ OPSCC necessitate new, evidence-based prognosticators. METHODS: A prospectively assembled cohort of 220, transoral surgery+neck dissection±adjuvant therapy-treated, p16+ OPSCC patients was analyzed...

BACKGROUND: Human papillomavirus-related (HPV+) oropharyngeal cancer is a rapidly emerging disease with generally good prognosis. Many prognostic algorithms for oropharyngeal cancer incorporate HPV status as a stratification factor, rather than recognising the uniqueness of HPV+ disease. The International Collaboration on Oropharyngeal cancer Network for Staging (ICON-S) aimed to develop a TNM classification specific to HPV+ oropharyngeal cancer. METHODS: The ICON-S study included patients with non-metastatic oropharyngeal cancer from seven cancer centres located across Europe and North America; one centre comprised the training cohort and six formed the validation cohorts...

For decades, the standard of care for radiation treatment of early larynx cancers has been conventional treatment using opposed lateral fields encompassing the larynx and overlying neck structures, including the adjacent carotid arteries. While intensity-modulated radiotherapy (IMRT) has replaced conventional radiotherapy for all other head/neck cancer situations, the use of IMRT to treat early glottic cancers remains controversial. The article reviews the published experience with IMRT for this clinical situation and provides a detailed review of the literature on radiation-induced carotid toxicity and how it might apply to the controversy...

INTRODUCTION: The recently updated meta-analysis of chemotherapy in head and neck cancer (MACH-NC) demonstrated the benefit of the addition of chemotherapy in terms of overall survival in head and neck squamous cell carcinoma (HNSCC). The magnitude of the benefit according to tumour site is unknown as well as their potential interactions with patient or trial characteristics. METHODS: Eighty seven randomized trials performed between 1965 and 2000 were included in the present analysis...

PURPOSE: Intensification of radiotherapy and chemotherapy for head-and-neck cancer may lead to increased rates of dysphagia. Dosimetric predictors of objective findings of long-term dysphagia were sought. METHODS AND MATERIALS: From an institutional database, 83 patients were identified who underwent definitive intensity-modulated radiotherapy for squamous cell carcinoma of the head and neck, after exclusion of those who were treated for a second or recurrent head-and-neck primary lesion, had locoregional recurrence at any time, had less than 12 months of follow-up, or had postoperative radiotherapy...

The salivary gland cancers are uncommon neoplasms of the head and neck, which exhibit considerable pathologic, biological, and clinical diversity. Surgical resection, often with postoperative radiation, is the standard therapeutic approach, and the results after treatment vary widely depending on the tumor histology. Chemotherapy has been of only limited palliative benefit in patients with advanced disease, and there has been little exploration of its use in definitive management. Recent investigation has focused on identification of the characteristic molecular signatures and genomic alterations of the specific histologic subtypes...
