Association between Locoregional Failure and NFE2L2/KEAP1/CUL3 Mutations in NRG/RTOG 9512: A Randomized Trial of Radiation Fractionation in T2N0 Glottic Cancer.

Purpose: NFE2L2/KEAP1/CUL3 mutations have been validated for radiation resistance in cell-based assays and animal models. However, clinical validation of these biomarkers has been challenging due to multimodality treatment regimens. This study aims to investigate the association between NFE2L2/KEAP1/CUL3 mutations and patient outcomes, including local failure (LF), locoregional failures (LRF), disease-free survival (DFS) and overall survival (OS), using samples from a phase III trial in which patients were treated with radiation monotherapy at 2 controlled doses.

Objective: To investigate perception, adoption and awareness of otolaryngologist-head neck surgeons (OTO-HNS) toward transoral robotic surgery (TORS).

Methods: An online survey was sent to 1383 OTO-HNS on the perception, adoption and awareness about TORS to members of many otolaryngological societies. The following aspects were assessed: TORS access; training; awareness/perception; indications and advantages/barriers to TORS practice.

Single-port robotic transcervical long-segment thoracic tracheal reconstruction: Cadaveric proof-of-concept study.

Objective: Slide tracheoplasty is the standard technique to repair congenital long-segment tracheal stenosis. This operation most commonly requires median sternotomy, which has drawbacks in young children. We hypothesized that a transcervical approach without sternotomy would be feasible if done with a single-port robotic system.

Methods: Between 2019 and 2020, five patients with glottic cancers underwent NF-SCPL-CHEP. The mean durations of surgical drains, tracheostomy canula, and nasogastric tube use were evaluated.

Minimally Invasive Surgery in the United States, 2022: Understanding Its Value Using New Datasets.

Introduction: While minimally invasive surgery (MIS) has transformed the treatment landscape of surgical care, its utilization is not well understood. The newly released Nationwide Ambulatory Surgery Sample allows for more accurate estimates of MIS volume in the United States-in combination with inpatient datasets.

Materials And Methods: Multiple nationwide databases from the Healthcare Cost and Utilization Project (HCUP) were used: the Nationwide Ambulatory Surgery Sample and National Inpatient Sample.

Head and Neck Virtual Coach: A Randomized Control Trial of Mobile Health as an Adjunct to Swallowing Therapy During Head and Neck Radiation.

Dysphagia is a common consequence of head and neck radiation and may be mitigated by performance of swallowing exercises during radiation treatment. Given historically poor adherence to such exercise protocols, we created a mobile health application, HNC Virtual Coach as an adjunct to standard clinical care. This randomized control trial investigated the impact of HNC Virtual Coach on adherence as well as swallowing outcomes by comparing those using the mobile app to those receiving only standard clinical care and paper logs.

Impact of Histologic Risk Factors on Recurrence Rates for Oral Cavity Squamous Cell Carcinoma.

Objectives: This study assesses the impact of adverse histologic risk factors including worst pattern of invasion (WPOI), predominant pattern of invasion (PPOI), tumor budding, and tumor infiltrating lymphocytes (TILS), on risk of recurrence in patients with early-stage Oral Cavity Squamous Cell Carcinoma (OCSCC).

Methods: Retrospective chart review was performed at a single institution to identify patients with OCSCC who underwent surgical excision. Inclusion criteria included T1-T2 stage disease based on AJCC seventh edition guidelines, no cervical lymph node involvement, no perineural invasion (PNI), no lymphovascular invasion (LVI), no post-operative adjuvant radiation therapy, and cancer involving only the oral tongue or floor of mouth.

Aldehyde dehydrogenase 3A1 deficiency leads to mitochondrial dysfunction and impacts salivary gland stem cell phenotype.

Adult salivary stem/progenitor cells (SSPC) have an intrinsic property to self-renew in order to maintain tissue architecture and homeostasis. Adult salivary glands have been documented to harbor SSPC, which have been shown to play a vital role in the regeneration of the glandular structures postradiation damage. We have previously demonstrated that activation of aldehyde dehydrogenase 3A1 (ALDH3A1) after radiation reduced aldehyde accumulation in SSPC, leading to less apoptosis and improved salivary function.

The genetic components (DNA) of human papillomavirus-related throat cancer (in the oropharynx) might be measured after surgery to help to predict whether treatment has been successful.

Soft robotic manipulator for intraoperative MRI-guided transoral laser microsurgery.

Magnetic resonance (MR) imaging (MRI) provides compelling features for the guidance of interventional procedures, including high-contrast soft tissue imaging, detailed visualization of physiological changes, and thermometry. Laser-based tumor ablation stands to benefit greatly from MRI guidance because 3D resection margins alongside thermal distributions can be evaluated in real time to protect critical structures while ensuring adequate resection margins. However, few studies have investigated the use of projection-based lasers like those for transoral laser microsurgery, potentially because dexterous laser steering is required at the ablation site, raising substantial challenges in the confined MRI bore and its strong magnetic field.

Using deep learning to identify the recurrent laryngeal nerve during thyroidectomy.

Surgeons must visually distinguish soft-tissues, such as nerves, from surrounding anatomy to prevent complications and optimize patient outcomes. An accurate nerve segmentation and analysis tool could provide useful insight for surgical decision-making. Here, we present an end-to-end, automatic deep learning computer vision algorithm to segment and measure nerves.

Landscape of innate lymphoid cells in human head and neck cancer reveals divergent NK cell states in the tumor microenvironment.

Natural killer (NK) cells comprise one subset of the innate lymphoid cell (ILC) family. Despite reported antitumor functions of NK cells, their tangible contribution to tumor control in humans remains controversial. This is due to incomplete understanding of the NK cell states within the tumor microenvironment (TME).
