The spectrum of tumors arising in the salivary glands is wide and has recently been shown to harbor a network of tumor-specific fusion genes. Acinic cell carcinoma (AciCC) is one of the more frequently encountered types of salivary gland carcinoma, but it has remained a genetic orphan until recently when a fusion between the HTN3 and MSANTD3 genes was described in one case. Neither of these 2 genes is known to be implicated in any other malignancy. Read More

Intraparotid facial nerve schwannoma (IFNS) is rarely observed in children compared with adults. Only a few cases have been reported in the literature. After radiological imaging and fine needle aspiration biopsy, an IFNS diagnosis may be skipped and confused with pleomorphic adenoma, which has a high prevalence among patients who have a mass in the parotid gland.

Purpose: The goal of this study was to generate a large treatment plan database for head-and-neck (H&N) cancer patients that can be considered as golden standard to train and validate models for knowledge-based (KB) treatment planning and QA. With this dataset the intrinsic prediction performance, the effect of inter-organ dependency and the impact of dataset inconsistency was investigated for an existing treatment planning QA model.
Methods: CT-scans of 108 previously treated oropharyngeal patients were used to establish the plan database. Read More

Purpose: In radiotherapy, it is necessary to characterize dose over the patient anatomy to target areas and organs at risk. Current tools provide methods to describe dose in terms of percentage of volume and magnitude of dose, but are limited by assumptions of anatomical homogeneity within a region of interest (ROI) and provide a non-spatially aware description of dose. A practice termed radio-morphology is proposed as a method to apply anatomical knowledge to parametrically derive new shapes and substructures from a normalized set of anatomy, ensuring consistently identifiable spatially-aware features of the dose across a patient set.

Swelling in the salivary glands, particularly parotid glands, is observed in approximately one third of Sjögren's syndrome patients. However, such patients should be assessed in terms of causes such as malignancies, infections, amyloidosis, sarcoidosis, and other autoimmune diseases when parotid gland swelling is noted. It should be considered that the incidence of lymphoma increases in Sjögren's syndrome. Read More

A 75-year-old man, who had been diagnosed with small lymphocytic lymphoma with cervical localization, underwent F-FDG PET/CT with iodinated contrast medium due to the appearance of cervical swelling suspected of illness relapse. PET/CT revealed intense F-FDG uptake in multiple cervical and subdiaphragmatic lymph nodes and in the left parotid. Moreover, diffuse uptake and wall thickening of the colon were evident; endoscopy with biopsy revealed a diffuse large B-cell lymphoma. Read More

Background: Advanced clinical applications, such as dose accumulation and adaptive radiation therapy, require deformable image registration (DIR) algorithms capable of voxel-wise accurate mapping of treatment dose or functional imaging. By utilizing a multistage deformable phantom, the authors investigated scenarios where biomechanical refinement method (BM-DIR) may be better than the pure image intensity based deformable registration (IM-DIR).
Methods: The authors developed a biomechanical-model based DIR refinement method (BM-DIR) to refine the deformable vector field (DVF) from any initial intensity-based DIR (IM-DIR). Read More

Importance: Whole-brain radiation therapy (WBRT) delivers a substantial radiation dose to the parotid glands, but the parotid glands are not delineated for avoidance and xerostomia has never been reported as an adverse effect. Minimizing the toxic effects in patients receiving palliative treatments, such as WBRT, is crucial.
Objective: To assess whether xerostomia is a toxic effect of WBRT. Read More

Acinic cell carcinoma (AciCC) is a low-grade malignancy which rarely metastasizes to bone or cavernous sinuses. A 62-year-old male patient, previously treated for AciCC of right parotid with surgery and local radiotherapy, presented 10 years later with progressive visual impairment and restriction of ocular movements. Magnetic resonance imaging of the head and orbit showed an expansile lobulated mass with heterogeneous signal intensity in bilateral cavernous sinus with encasement of the internal carotid artery on both sides.

Salivary gland acinar cells use the calcium ([Formula: see text]) ion as a signalling messenger to regulate a diverse range of intracellular processes, including the secretion of primary saliva. Although the underlying mechanisms responsible for saliva secretion are reasonably well understood, the precise role played by spatially heterogeneous intracellular [Formula: see text] signalling in these cells remains uncertain. In this study, we use a mathematical model, based on new and unpublished experimental data from parotid acinar cells (measured in excised lobules of mouse parotid gland), to investigate how the structure of the cell and the spatio-temporal properties of [Formula: see text] signalling influence the production of primary saliva.

Purpose: Radiation therapy (RT) is a common treatment option for head and neck (HaN) cancer. An important step involved in RT planning is the delineation of organs-at-risks (OARs) based on HaN computed tomography (CT). However, manually delineating OARs is time-consuming as each slice of CT images needs to be individually examined and a typical CT consists of hundreds of slices. Read More

Background: A new strategy is introduced combining the use of Multi-Criteria Optimization-based Trade-Off Exploration (TO) and RapidPlan™ (RP) for the selection of optimisation parameters that improve the trade-off between sparing of organs at risk (OAR) and target coverage for head and neck radiotherapy planning. Using both approaches simultaneously; three different workflows were proposed for the optimisation process of volumetric-modulated arc therapy (VMAT) plans. The generated plans were compared to the clinical plans and the plans that resulted using RP and TO individually. Read More
