Nodular fasciitis is a benign, reactive, tumor-like lesion composed of fibroblasts and myofibroblasts. It typically occurs in the extremities and the trunk. Head and neck localization is 13-20%. As it grows rapidly, clinicians frequently misdiagnose it as an aggressive or a malignant lesion. Some lesions show moderate cellularity, mild cellular atypia, and mitosis histologically causing pathologists to over-diagnose the lesion as a malignant tumor. It is important to diagnose nodular fasciitis correctly to avoid unnecessary additional surgery and treatment...

BACKGROUND: Long-term laryngectomy-free (LFS), tumour-specific (TSS) and overall survival (OS) is achieved by non-surgical larynx preservation (LP) only in a proportion of patients with locally advanced laryngeal or hypopharyngeal cancer. A score facilitating decision-making after 1 cycle induction chemotherapy (IC-1) may improve LFS and TSS. METHODS: Early response to IC-1 with TPF ± cetuximab was assessed in 52 patients using endoscopic tumour staging for selecting total laryngectomy for non-responders with endoscopic tumour surface shrinkage <30% versus induction chemotherapy plus radiotherapy (IC + RT) for responders...

For the treatment of T1b glottic carcinoma, different treatment options, such as transoral laser microsurgery, open surgical techniques, and primary radiotherapy, are under discussion. In this context, the aim of the present study was to describe oncologic results and complication rates of transoral laser microsurgery in treatment of T1b glottic carcinoma. This is a retrospective unicenter chart review of patients treated at an academic tertiary referral center between 1986 and 2006. Fifty-one previously untreated T1b cases were exclusively treated by transoral laser microsurgery and included into this study, 47 were male, and 4 were female...

BACKGROUND: Single-modality radiotherapy is considered a standard-of-care option for certain stage III, T1-2N1 head and neck squamous cell carcinomas (HNSCCs). The role of concomitant chemoradiation is not well established because there have been no studies comparing chemoradiation with radiation alone in this population. METHODS: This study analyzed patients in the National Cancer Data Base with cT1-2N1M0 invasive squamous cell carcinomas of the oropharynx, larynx, and hypopharynx who were diagnosed between 2004 and 2012 and were undergoing definitive radiation...

To evaluate the incidence of a subsequent primary thyroid malignancy in patients with an index head and neck squamous cell carcinoma (HNSCC), we analyzed the National Cancer Institute's Surveillance, Epidemiology, and End Results database to identify a cohort of patients who had been diagnosed with a primary HNSCC from 1973 through 2004. The study population was made up of 60,323 patients of all ages, roughly three-quarters of whom were male. A total of 60 patients (0.1%) developed a subsequent thyroid malignancy-not a statistically significant finding...

T E Marchant, K D Joshi
Accurate knowledge of ionizing radiation dose from cone-beam CT (CBCT) imaging in radiotherapy is important to allow concomitant risks to be estimated and for justification of imaging exposures. This study uses a Monte Carlo CBCT model to calculate imaging dose for a wide range of imaging protocols for male and female patients. The Elekta XVI CBCT system was modeled using GATE and simulated doses were validated against measurements in a water tank and thorax phantom. Imaging dose was simulated in the male and female ICRP voxel phantoms for a variety of anatomical sites and imager settings (different collimators, filters, full and partial rotation)...

BACKGROUND: Radiation therapy-related dysphagia is worsened by xerostomia. The submandibular glands (SMG) produce saliva rich in lubricating mucins, and sparing the SMG has been shown to reduce xerostomia. The goal of this study was to determine whether SMG sparing IMRT is associated with reduced post-treatment PEG dependence in locally advanced oropharynx cancer patients. METHODS: Patients treated with definitive radiation therapy for oropharynx cancer were included in this retrospective study...

INTRODUCTION: Role of radiotherapy in comprehensive management of head and neck cancer for achieving tumour control and organ preservation is now well established and radiotherapy is routinely used in adjuvant setting after surgery, concurrently with chemotherapy or targeted agents and for palliation. Development of linear accelerator with Multileaf Collimator (MLC) have revolutionized radiation delivery techniques, allowing conformal and Intensity Modulated Radiotherapy (IMRT) to deliver highly conformal sculpted radiation dose to a very complex structure with improved sparing of adjoining critical structures like salivary glands, spinal cord, eyes, brainstem and larynx amounting to better therapeutic gain...
