The proliferation marker Chromatin Assembly Factor-1 is of clinical value in predicting the biological behaviour of salivary gland tumours. [PDF]

open access: yes, 2011
Salivary gland tumours (SGT) constitute a diagnostically challenging group of neoplasms with frequently unpredictable clinical outcome. The proliferation rate facilitates the identification of aggressive SGT.

Mathematical models for order of mutation problem in myeloproliferative neoplasm: non-additivity and non-commutativity [PDF]

open access: yesarXiv, 2023
In some patients of myeloproliferative neoplasm, two genetic mutations can be found: JAK2 V617F and TET2. When one mutation is present or not, the other mutation has different effects on regulating gene expressions. Besides, when both mutations are present, the order of occurrence might make a difference.

MALDI Mass Spectrometry Imaging Highlights Specific Metabolome and Lipidome Profiles in Salivary Gland Tumor Tissues

open access: yesMetabolites, 2022
Salivary gland tumors are relatively uncommon neoplasms that represent less than 5% of head and neck tumors, and about 90% are in the parotid gland. The wide variety of histologies and tumor characteristics makes diagnosis and treatment challenging.

Investigating heterogeneous PSMA ligand uptake inside parotid glands [PDF]

open access: yesPhysica Medica: European Journal of Medical Physics, 2024
The purpose was to investigate the spatial heterogeneity of prostate-specific membrane antigen (PSMA) positron emission tomography (PET) uptake within parotid glands. We aim to quantify patterns in well-defined regions to facilitate further investigations.

Order-of-mutation effects on cancer progression: models for myeloproliferative neoplasm [PDF]

open access: yesarXiv, 2023
We develop a modeling framework for cancer progression that distinguishes the order of two possible mutations. Recent observations and information on myeloproliferative neoplasms are analyzed within our framework. In some patients with myeloproliferative neoplasms, two genetic mutations can be found, JAK2 V617F and TET2.

Role of Fine Needle Aspiration Cytology in Salivary Gland Pathology and its Histopathological Correlation: A Two Year Prospective Study in Western India. [PDF]

open access: yes, 2012
Background and objectives: Salivary gland lesions account for 2-6.5% of all the neoplasms of the head and neck. Fine needle aspiration cytology (FNAC) is being increasingly used in the diagnosis of salivary gland lesions.

Review of salivary gland neoplasms [PDF]

open access: yes, 2012
Salivary gland tumours most often present as painless enlarging masses.Most are located in the parotid glands andmost are benign. The principal hurdle in their management lies in the difficulty in distinguishing benign from malignant tumours ...

Advantages and limitations of navigation‐based multicriteria optimization (MCO) in selectively sparing pharyngeal constrictor muscles in head and neck radiotherapy treatment planning

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose Sparing pharyngeal constrictor muscles (PCMs) during radiotherapy improves patient‐reported swallowing function. This study aimed to explore the feasibility of integrating knowledge‐based planning (KBP) with multicriteria optimization (MCO) in Eclipse v18.0 to selectively spare PCM, quantify the required trade‐off in prophylactic ...

Myoepithelioma of the Parotid Gland: A Case Report with Review of the Literature and Classic Histopathology

open access: yesCase Reports in Otolaryngology, 2017
Myoepithelioma is a rare salivary gland neoplasm. They most commonly affect the major and minor salivary glands with the parotid gland being the most common, approximately 40%. Only 1% of all salivary gland neoplasms are myoepitheliomas.
