Distinct microbiome dysbiosis and epigenetic anomaly in esophageal adenocarcinoma and its underlying Barrett's esophagus.

Interaction between host genotoxic changes and mucosa-associated microbiome (MAM) dysbiosis may have a role in various digestive cancers. We investigated MAM in Barrett's esophagus (BE) and esophageal adenocarcinoma (EAC) progression sequence and its association with host genotoxic changes. 16S rRNA gene sequencing was performed in three different groups of biopsies from nonneoplastic BE from patients without cancer (N, normal group; n = 47) and with EAC (ADJ, adjacent group; n = 27).

Predictive factors for failure of neoadjuvant docetaxel, cisplatin, and 5-fluorouracil therapy in esophageal squamous cell carcinoma.

Recently, neoadjuvant chemotherapy comprising docetaxel, cisplatin, and 5-fluorouracil showed promising efficacy for esophageal squamous cell carcinoma. However, some patients do not achieve curative resection despite neoadjuvant chemotherapy using these drugs. This study aimed to clarify the pretherapeutic characteristics of these patients.

Enhanced Cross-stage-attention U-Net for esophageal target volume segmentation.

Purpose: The segmentation of target volume and organs at risk (OAR) was a significant part of radiotherapy. Specifically, determining the location and scale of the esophagus in simulated computed tomography images was difficult and time-consuming primarily due to its complex structure and low contrast with the surrounding tissues. In this study, an Enhanced Cross-stage-attention U-Net was proposed to solve the segmentation problem for the esophageal gross tumor volume (GTV) and clinical tumor volume (CTV) in CT images.

Computer-aided endoscopic diagnostic system modified with hyperspectral imaging for the classification of esophageal neoplasms.

Introduction: The early detection of esophageal cancer is crucial to enhancing patient survival rates, and endoscopy remains the gold standard for identifying esophageal neoplasms. Despite this fact, accurately diagnosing superficial esophageal neoplasms poses a challenge, even for seasoned endoscopists. Recent advancements in computer-aided diagnostic systems, empowered by artificial intelligence (AI), have shown promising results in elevating the diagnostic precision for early-stage esophageal cancer.

Second primary cancers: Incidence and outcomes from a population of patients accrued in six prospective controlled trials at a tertiary cancer institute.

Background: The aim of this study was to document the incidence, spectrum and outcomes of Second Primary Malignancy (SPM) in a prospectively followed-up population of Head and Neck Squamous carcinoma (HNSCC) patients accrued in six prospective trials and treated with definitive radiotherapy.

Materials And Methods: Patients were prospectively followed up over time and data on SPM collected after IRB approval after establishing the diagnosis of SPM based on clinical criteria. Descriptive statistics to determine clinic demographic characteristics and spectrum of SPM encountered, time to event outcomes (SPM-DFS - Disease-free survival after diagnosis of second primary, SPM-OS - Overall survival after diagnosis of second primary) and univariate analysis of factors of likely prognostic significance were performed.

Should we pay more attention to the potential link between and esophageal cancer in Asian countries.

The presence of () infection has been indicated to have a protective influence on esophageal cancer (EC) in some studies, but its specific impact on the risk of esophageal squamous cell carcinoma and esophageal adenocarcinoma remains inconclusive. This manuscript comment addresses the recent study by López-Gómez . Despite it was a retrospective observational study without a control group, this study revealed a notably low prevalence of infection among EC patients, indicating a potential association between and EC in Spain.

Treatment strategies for limited-stage small cell carcinoma of the esophagus: evidence from a Chinese multicenter cohort study and the American SEER database.

Background: The rare incidence of small cell carcinoma of the esophagus (SCCE) makes prospective studies difficult to conduct, the efficacy of existing standard treatment regimens for SCCE is therefore highly controversial. This study aimed to explore differences in the efficacy of three different treatment regimens [upfront surgery, neoadjuvant chemotherapy (NCT), and chemoradiotherapy (CRT)] in patients with limited-stage SCCE (LS-SCCE).

Methods: In total, 483 patients with LS-SCCE were screened from five centers from June 2001 to June 2020, and 128 patients with LS-SCCE were screened from the Surveillance, Epidemiology, and End Results (SEER) database.

Demographic analysis of survival trends in squamous cell carcinoma of the upper 1/3 of the esophagus: a population-based study.

Esophageal malignancies, constituting 3% of global cancers, pose significant health challenges with poor survival rates. Squamous Cell Carcinoma (SCC) and Adenocarcinoma (AC) are predominant subtypes, with shifting incidences globally. This analysis will focus primarily on the demographics of survival trends for Squamous cell carcinoma of esophagus (SCCE).

RFC4 confers radioresistance of esophagus squamous cell carcinoma through regulating DNA damage response.

Radioresistance in esophageal squamous cell carcinoma (ESCC) is a critical factor leading to treatment failure and recurrence, yet its underlying molecular mechanisms remain unclear. This study aimed to investigate the role of Replication Factor C4 (RFC4) in ESCC radioresistance and to explore the underlying mechanisms. We utilized online bioinformatics tools to analyze the properties, functions, and prognostic significance of RFC4 in ESCC.

The rare coexistence of gastric and esophagus squamous cell carcinoma: a case report.

Squamous cell carcinoma (SCC) of the stomach is a rare entity with fewer than 100 cases of primary SCC reported in the literature, while esophageal SCC is prevalent and more common. However, a synchronous squamous cell carcinoma found in the esophagus and stomach remains very uncommon. We present the case of a 64-year-old with a history of dysphagia who had an endoscopy that showed an impassable stenosis of the middle esophagus, with histopathology in favor of an esophagus squamous cell carcinoma.

The paradox of : how does infection protect against esophageal cancer?

is a microaerophilic gram-negative bacterium infecting around half of the world's population. Despite its well-known role in gastric malignancies, its impact on esophageal cancer comes with a complex paradox. Several mechanisms have been proposed to explain its observed lack of carcinogenic activity in the esophagus, including the trigger of anti-inflammatory pathways, promoting atrophic gastritis, and esophageal microbiome modulation.

Characteristics of Esophageal Squamous Cell Carcinomas Based on Circumferential Localization.

Background And Aim: In terms of their longitudinal positioning, esophageal squamous cell carcinoma (ESCC) commonly arises in the middle segment of the esophagus. However, limited attention has been given to the circumferential aspect. This study aimed to investigate the prevalence and characteristics of ESCC lesions resected via endoscopic submucosal dissection (ESD), taking into consideration both longitudinal and circumferential positions.
