Alterations to the Esophageal Microbiome Associated with Progression from Barrett's Esophagus to Esophageal Adenocarcinoma

open access: yesCancer Epidemiology, Biomarkers and Prevention, 2019
Background: The incidence of esophageal adenocarcinoma has risen dramatically over the past half century, and the underlying reasons are incompletely understood. Broad shifts to the upper gastrointestinal microbiome may be partly responsible. The goal of

An investigation of the progression from Barrett's esophagus to adenocarcinoma [PDF]

open access: yes, 2016
Barrett's esophagus is a metaplasia of the epithelium of the lower esophagus from a normal squamous appearance to a columnar appearance more typically found in the stomach. It is normally caused by prolonged gastric reflux. While Barrett's esophagus is

Esophageal Cancer Initially Thought to be Accompanied by a Solitary Metastasis to an Intrathoracic Paraaortic Lymph Node [PDF]

open access: yes, 2012
Esophageal cancers usually exhibit lymph-node metastases. Although a solitary lymph-node metastasis is occasionally found, the involvement of an intrathoracic paraaortic node is rare.

Risk factors and prediction models for severe radiation-induced oral mucositis in patients with nasopharyngeal carcinoma undergoing chemoradiotherapy

open access: yesDiscover Oncology
Objective This study aimed to investigate the factors associated with severe radiation-induced oral mucositis (SRIOM) in nasopharyngeal carcinoma (NPC) patients undergoing chemoradiotherapy (CRT) and to establish a prediction model for SRIOM.

Pressure -- area loop based phenotypic classification and mechanics of esophagogastric junction physiology [PDF]

open access: yesarXiv, 2022
The esophagogastric junction (EGJ) is located at the distal end of the esophagus and acts as a valve allowing swallowed materials to enter the stomach and preventing acid reflux. Irregular weakening or stiffening of the EGJ muscles result in changes to its opening and closing patterns which can progress into esophageal disorders.

Cell‐free and extracellular vesicle microRNAs with clinical utility for solid tumors

open access: yesMolecular Oncology, EarlyView.
Cell‐free microRNAs (cfmiRs) are small‐RNA circulating molecules detectable in almost all body biofluids. Innovative technologies have improved the application of cfmiRs to oncology, with a focus on clinical needs for different solid tumors, but with emphasis on diagnosis, prognosis, cancer recurrence, as well as treatment monitoring.

Generalizable Cone Beam CT Esophagus Segmentation Using Physics-Based Data Augmentation [PDF]

open access: yesarXiv, 2020
Automated segmentation of esophagus is critical in image guided/adaptive radiotherapy of lung cancer to minimize radiation-induced toxicities such as acute esophagitis. We developed a semantic physics-based data augmentation method for segmenting esophagus in both planning CT (pCT) and cone-beam CT (CBCT) using 3D convolutional neural networks.

Incidence of adenocarcinoma among patients with Barrett's esophagus.

open access: yesNew England Journal of Medicine, 2011
BACKGROUND Accurate population-based data are needed on the incidence of esophageal adenocarcinoma and high-grade dysplasia among patients with Barrett's esophagus.

Comparing self‐reported race and genetic ancestry for identifying potential differentially methylated sites in endometrial cancer: insights from African ancestry proportions using machine learning models

open access: yesMolecular Oncology, EarlyView.
Integrating ancestry, differential methylation analysis, and machine learning, we identified robust epigenetic signature genes (ESGs) and Core‐ESGs in Black and White women with endometrial cancer. Core‐ESGs (namely APOBEC1 and PLEKHG5) methylation levels were significantly associated with survival, with tumors from high African ancestry (THA) showing ...

Substance use and esophageal neuroendocrine neoplasm: A case–control study

open access: yesKaohsiung Journal of Medical Sciences, 2022
Esophageal neuroendocrine neoplasms (NEN) are extremely rare and little is known about their risk factors. To identify the potential risk factors, we evaluated whether the history of substance use, including alcohol, tobacco and areca nut consumption was
