Case Report: Large Cell Neuroendocrine Carcinoma of the Palatine Tonsil in a 76‐Year‐Old Patient

open access: yesHead &Neck, EarlyView.
ABSTRACT Background Large cell neuroendocrine carcinoma (LCNEC) of the palatine tonsil is an extremely rare malignancy characterized by an aggressive clinical course and poor prognosis. Its nonspecific presentation often delays diagnosis. Methods We present the case of a 76‐year‐old female patient admitted to the Emergency Department with throat ...

How to increase the reactivity of [18F]fluoroethyl bromide: [18F]fluoroethylation of amine, phenol and amide functional groups with [18F]FEtBr, [18F]FEtBr/NaI and [18F]FEtOTf

open access: yes
[18F]Fluoroethyl bromide ([18F]FEtBr) is a useful synthetic precursor to synthesize 18F-labeled compounds. However, the lower reactivity of [18F]FEtBr with amine, phenol and amide functional groups than that of [11C]CH3I partly limits its wide ...

Early Feasibility of Registration of Micro‐PET/CT Scans to Annotated 3D Specimen Models

open access: yesHead &Neck, EarlyView.
ABSTRACT Background Intraoperative 18F‐fluorodeoxyglucose (18F‐FDG) micro‐positron emission tomography/computed tomography (micro‐PET/CT) is an emerging modality for margin assessment. Prior to clinical use, micro‐PET/CT margin distances must be correlated with gold‐standard histopathology.

Complete Pathologic Response to Neoadjuvant Pembrolizumab Captured on Intraoperative PET/CT: A Case Report and Exploratory Analysis

open access: yesHead &Neck, EarlyView.
ABSTRACT Background Neoadjuvant immunotherapy is an emerging treatment for patients with head and neck cancer. Given the heterogeneity of response, novel methods of intraoperative tumor and margin assessment warrant investigation. Methods A 55‐year‐old male presented with a cT3N2c supraglottic squamous cell carcinoma with a combined positive score of 5.

Pretreatment EBV‐DNA/TLG‐Based Risk Stratification Is Associated With Survival Outcomes in Nonmetastatic Nasopharyngeal Carcinoma: An Exploratory Study

open access: yesInternational Journal of Cancer, EarlyView.
ABSTRACT Whether combining pretreatment plasma Epstein–Barr virus DNA (EBV‐DNA) with 18F‐FDG PET/CT‐derived total lesion glycolysis (TLG) improves prognostic stratification in nonmetastatic nasopharyngeal carcinoma (NPC) is unclear, particularly in nonendemic populations.

Real‐World Experience With Multimodal Treatment of Resectable Stage II–III Non‐Small Cell Lung Cancer: A Single Institutional Analysis

open access: yesInternational Journal of Cancer, EarlyView.
ABSTRACT Neoadjuvant therapy has recently become an integral component of multimodal treatment for resectable lung cancer. However, real‐world data on perioperative morbidity and treatment adherence remain limited. This study aimed to assess the feasibility and safety of different neoadjuvant treatment approaches applied within daily clinical routine ...

Metagenomic and culture‐based insights into host and plasmid contexts of high‐risk ARGs in poultry farm environments

open access: yesiMetaOmics, EarlyView.
Shotgun metagenomics and culture‐based isolate genomics revealed position‐associated high‐risk antibiotic resistance genes (ARGs) signals across poultry manure piles and surrounding soils. Culture‐confirmed Enterobacteriaceae and IncHI2A‐related blaNDM‐5 plasmid backgrounds further highlight priority host‐ARG‐plasmid contexts for farm antimicrobial ...

Hypervision Proton Surgery: The Future Direction of Proton Therapy

open access: yesiNew Medicine, EarlyView.
ABSTRACT Proton beams provide unique physical advantages characterized by a low entrance dose, negligible exit dose, and a sharp Bragg peak, which enable superior sparing of normal tissues and support safe dose escalation for improved tumor control. However, conventional photon‐based fractionation remains widely used in proton therapy, where prolonged ...

Development of scandium-catalyzed N-[18F]fluoroalkylation of aryl and heteroaryl amines with [18F]epifluorohydrin.

open access: yes, 2019
Objectives: [18F]Fluoroalkylation is a useful method for introduction of fluorine-18 into molecules containing NH, OH, and SH-groups. Using various [18F]fluoroalkylating agents, we are routinely producing clinically-useful 18F-radiotracers, such as [18F ...

Ovarian Cancer: Epidemiology, Disease Mechanisms, New Diagnosis and Treatment Strategies, and Research Directions

open access: yesiNew Medicine, EarlyView.
ABSTRACT Ovarian cancer (OC) continues to be the deadliest gynecological malignancy and a significant cause of cancer‐related mortality among women worldwide. Standard treatment strategies typically entail platinum‐based chemotherapy in conjunction with cytoreductive surgery.
