Differences in PD‐L1, PD‐L2, and EGFR Expression Between Naive and Recurrent Tumors in Patients With Head and Neck Squamous Cell Carcinoma: A Retrospective Study

Head &Neck, EarlyView.
ABSTRACT Background The efficacy of anti‐PD‐1 and EGFR therapies for head and neck squamous cell carcinoma (HNSCC) can be predicted using various markers; however, the stability of these markers remains unclear. Methods In this retrospective study, laboratory findings and tissue expression of PD‐L1, PD‐L2, and EGFR were analyzed in 79 paired naive and ...

Perspective: Speculative role of Tmp21 mediated protein secretory pathway during endoplasmic reticulum (ER) stress induced chronic inflammation [PDF]

arXiv, 2016
By deploying myelofibrosis as the disease context, I wish to propose that increased availability of Tmp21 (an NFAT gene target) induces aberrant protein secretion from the ER contributing to pathological consequences, which has not been elucidated before.

HPV‐Positive Squamous Cell Carcinoma Metastasis Without Clinical Evidence of Primary: The Posterior Oropharyngeal Wall May Be an Overlooked Location

Head &Neck, EarlyView.
ABSTRACT Background Oropharyngeal squamous cell carcinoma (SCC) can present as cancer of unknown primary, where only cervical lymph node metastases are identified. Most tumors, particularly human‐papillomavirus‐associated ones, are located in the palatine/lingual tonsils.

Forecasting Leading Death Causes in Australia using Extended CreditRisk$+$ [PDF]

arXiv, 2015
Recently we developed a new framework in Hirz et al (2015) to model stochastic mortality using extended CreditRisk$^+$ methodology which is very different from traditional time series methods used for mortality modelling previously. In this framework, deaths are driven by common latent stochastic risk factors which may be interpreted as death causes ...

Acoustic Features of Airway Protective Maneuvers as Biomarkers of Radiation‐Associated Dysphagia and Penetration/Aspiration in Head and Neck Cancer Patients

Head &Neck, EarlyView.
ABSTRACT Background This study aimed at identifying acoustic features of airway protective maneuvers as biomarkers of radiation‐associated dysphagia, involving penetration/aspiration and pharyngeal residue. Methods Temporal and spectral acoustical analyses were carried out on voluntary coughs, voluntary throat clearings, and reflexive coughs.

Deep Multi-Modal Classification of Intraductal Papillary Mucinous Neoplasms (IPMN) with Canonical Correlation Analysis [PDF]

arXiv, 2017
Pancreatic cancer has the poorest prognosis among all cancer types. Intraductal Papillary Mucinous Neoplasms (IPMNs) are radiographically identifiable precursors to pancreatic cancer; hence, early detection and precise risk assessment of IPMN are vital.

First Case of Lateral Oropharyngectomy Performed Using the Vitom Eagle: A Novel Exoscopic System for Transoral Surgery

Head &Neck, EarlyView.
ABSTRACT Background The Vitom Eagle is a novel exoscopic system, specifically designed for transoral surgery (e.g., lateral oropharyngectomy). No prior study has compared it to existing surgical systems. Methods This case report examines a patient affected by HPV‐related oropharyngeal squamous cell carcinoma treated with transoral lateral ...

A phase Ⅱ prospective trial of photobiomodulation therapy in limiting oral mucositis in the treatment of locally advanced head and neck cancer patients

World Journal of Otorhinolaryngology - Head and Neck Surgery, Volume 8, Issue 4, Page 345-354, December 2022., 2022
Abstract Objective This study aimed to compare the historical incidence rate of severe oral mucositis (OM) in head and neck cancer patients undergoing definitive concurrent chemoradiation therapy (CRT) versus a prospective cohort of patients with locally advanced head and neck squamous cell carcinoma (HNSCC) treated with prophylactic photobiomodulation
