The oral microbiome potentially wields significant influence in the development of cancer. Within the human oral cavity, an impressive diversity of more than 700 bacterial species resides, making it the second most varied microbiome in the body. This finely balanced oral microbiome ecosystem is vital for sustaining oral health. However, disruptions in this equilibrium, often brought about by dietary habits and inadequate oral hygiene, can result in various oral ailments like periodontitis, cavities, gingivitis, and even oral cancer. There is compelling evidence that the oral microbiome is linked to several types of cancer, including oral, pancreatic, colorectal, lung, gastric, and head and neck cancers. This review discussed the critical connections between cancer and members of the human oral microbiota. Extensive searches were conducted across the Web of Science, Scopus, and PubMed databases to provide an up-to-date overview of our understanding of the oral microbiota\'s role in various human cancers. By understanding the possible microbial origins of carcinogenesis, healthcare professionals can diagnose neoplastic diseases earlier and design treatments accordingly.

Esophageal perforation, a rare and serious condition, has seen a reduction in mortality from 30% to 15% over the last three decades due to advancements such as gastrointestinal stents, minimally invasive surgeries, and improved interventional radiology techniques. This review analyzes management strategies for esophageal perforation based on 14 English-language articles published from 2009 to 2024, primarily utilizing surveys and national database analyses. The management of esophageal perforation is complex, with challenges in diagnosis and treatment strategy. Despite surgery being the traditional treatment, the role of less invasive methods is growing. Effective management of esophageal perforation involves advanced imaging for diagnosis, hemodynamic stabilization, and a multidisciplinary approach to treatment, including surgical and non-surgical interventions. The evidence for different treatment outcomes remains limited, highlighting the need for comprehensive care involving thoracic surgery, interventional radiology, gastroenterology, and critical care in an intensive care unit setting.

UNASSIGNED: Sleep quality is a notable factor of well-being. It also may play a role in the development and progression of chronic diseases and cancers. Therefore, this study was performed to investigate poor sleep quality and its influencing factors among Iranian patients with esophageal and gastric cancer.
UNASSIGNED: In this cross-sectional study, a total of 312 Iranian adult patients who suffered from esophageal and gastric cancers were employed from a gastrointestinal cancer-based cohort study conducted in a referral hospital in Tehran between 2015 and 2018. Persian version of the Pittsburg Sleep Quality Index (PSQI) was used to measure poor sleep quality. Univariate and multiple logistic regression models were applied to determine the related factors to poor sleep quality.
UNASSIGNED: Of the participants, 203 (65.06%) were men, and 75.96% had gastric cancer. The mean age was 63.13±12.10 years. The results demonstrated that more than 62% of the patients had poor sleep quality. 148 (62.44%) patients out of 237 patients with gastric cancer had poor-quality sleep. Also, 46 (64.38%) patients out of 237 patients with esophageal cancer had poor-quality sleep. Based on the results of multiple logistic regression models, marital status has a negative association with poor sleep quality (odds ratio [OR]=0.32, P=0.015). In addition, having chronic disease (OR=2.16; P=0.028) and wealth index (OR=3.11, P=0.013; OR=3.81, P=0.003; OR=3.29, P=0.009; OR=3.85, P=0.003 for rich, moderate, poor, and poorest subgroups, respectively) had a positive association with poor sleep quality.
UNASSIGNED: The findings showed that about two-thirds of the patients studied were poor sleepers. Also, it was observed that marital status, chronic disease, and wealth index were important factors associated with poor sleep quality.

UNASSIGNED: Glomus tumors are typically benign soft tissue tumors that occur at the extremities; malignant and viscerally occurring cases are extremely rare.
UNASSIGNED: We report a 49-year old male patient with a malignant esophageal glomus tumor that was complicated by lung and liver metastases. Genetic test results guided the patient\'s individualized treatment. Consequently, treatment with Anlotinib combined with Tislelizumab achieved significant clinical benefits.
UNASSIGNED: Our case report demonstrates that immunotherapy combined with anti-angiogenic therapy in patients with malignant esophageal glomus tumors can achieve significant efficacy and suggests the potential value of next-generation sequencing (NGS) detection in guiding personalized treatments in patients with malignant esophageal glomus tumors.

UNASSIGNED: Esophageal gastrointestinal stromal tumors (E-GISTs) are highly uncommon and have not been thoroughly examined.
UNASSIGNED: The objective of this multi-center study was to assess the viability of endoscopic resection (ER) in the treatment of E-GISTs and to explore its clinical implications.
UNASSIGNED: This was a multi-center retrospective study. Consecutive patients referred to the four participating centers.
UNASSIGNED: E-GISTs among the consecutive subepithelial tumors (SETs) treated by ER methods were enrolled from April 2019 to August 2022. Clinicopathological, endoscopic, and follow-up data were collected and analyzed.
UNASSIGNED: A total of 23 patients with E-GISTs were included for analysis, accounting for 1.9% of all the esophageal SETs (1243 patients). The average size of the tumor lesions was 2.3 cm (range 1.0-4.0 cm). We observed that tumors larger than 2.0 cm were more likely to grow deeper, with a statistically significant difference (p < 0.001). End bloc resection was achieved in all 23 patients. The mean operation time was 53.6 min (range 25-111 min). One patient experienced significant intraoperative bleeding, which was promptly managed endoscopically without necessitating surgery. The average hospital stay was 4.5 days (range 3-8 days). The overall median follow-up period was 31 months (range 13-47 months). No tumor recurrence, residual tumor, distal metastasis, or death was observed during the follow-up period.
UNASSIGNED: Based on our limited data, our study indicates that ER may be a feasible and effective option for treating esophageal GISTs measuring 4 cm or less. We suggest submucosal tunnel endoscopic resection as the preferred approach, as all E-GISTs in our study were situated in the muscularis propria layer. Additionally, tumors larger than 2 cm were more prone to deeper growth or extraluminal extension.

Esophageal squamous cell carcinoma (ESCC) is a deadly consequence of radiation exposure to the esophagus. ESCC arises from esophageal epithelial cells that undergo malignant transformation and features a perturbed squamous cell differentiation program. Understanding the dose- and radiation quality-dependence of the esophageal epithelium response to radiation may provide insights into the ability of radiation to promote ESCC. We have explored factors that may play a role in esophageal epithelial radiosensitivity and their potential relationship to ESCC risk. We have utilized a murine three-dimensional (3D) organoid model that recapitulates the morphology and functions of the stratified squamous epithelium of the esophagus to study persistent dose- and radiation quality-dependent changes. Interestingly, although high-linear energy transfer (LET) Fe ion exposure induced a more intense and persistent alteration of squamous differentiation and 53BP1 DNA damage foci levels as compared to Cs, the MAPK/SAPK stress pathway signaling showed similar altered levels for most phospho-proteins with both radiation qualities. In addition, the lower dose of high-LET exposure also revealed nearly the same degree of morphological changes, even though only ~36% of the cells were predicted to be hit at the lower 0.1 Gy dose, suggesting that a bystander effect may be induced. Although p38 and ERK/MAPK revealed the highest levels following high-LET exposure, the findings reveal that even a low dose (0.1 Gy) of both radiation qualities can elicit a persistent stress signaling response that may critically impact the differentiation gradient of the esophageal epithelium, providing novel insights into the pathogenesis of radiation-induced esophageal injury and early stage esophageal carcinogenesis.

UNASSIGNED: Esophageal carcinoma with switch/sucrose nonfermenting (SWI/SNF)-related, matrix-associated, actin-dependent regulator of chromatin, subfamily A, member 4 (SMARCA4) mutation is a rare variant of malignant esophageal epithelial neoplasm, which is characterized by the loss of SMARCA4/BRG1 protein on immunohistochemistry or alterations in the SMARCA4 gene on sequencing. Only a few case series and case reports of esophageal carcinoma with SMARCA4 mutations have been published in the English literature; the rarity of the disease poses significant diagnostic challenges for surgical pathologists and could potentially lead to delayed or suboptimal patient care. Herein, we reviewed the available literature on esophageal carcinoma with SMARCA4 mutations to discuss its epidemiology, clinical presentation, pathological and molecular features, diagnostic challenges, treatment, and prognosis.
UNASSIGNED: The PubMed, Scopus, Ovid, and Google Scholar databases were extensively reviewed. The references included in the articles were cross-examined to identify any missing articles. We searched for all published literature on esophageal carcinoma with SMARCA4 mutations from inception of the databases to date.
UNASSIGNED: Esophageal carcinoma with SMARCA4 mutations is most common in middle-aged and older men. Barrett esophagus and gastroesophageal reflux disease (GERD) are the most associated risk factors. Dysphagia was the most common initial clinical presentation. Esophagogastroduodenoscopy (EGD) is the preferred diagnostic modality. Microscopically, the tumor cells exhibited epithelioid features mixed with variable components of rhabdoid and glandular differentiation. The tumor cells showed variable immunoreactivity for cytokeratin and sometimes weakly expressed neuroendocrine or B-lymphocyte markers (Pax5), which are potential diagnostic pitfalls. Melanoma marker tests showed negative results. The SMARCB1/INI1 protein remains intact, and a definitive diagnosis necessitates the presence of either SMARCA4/BRG1 protein loss or SMARCA4 gene mutations. Esophageal carcinoma with SMARCA4 mutations shows overly aggressive behavior and presents with advanced stages of disease; most patients succumb to the disease within 1 year of initial diagnosis.
UNASSIGNED: Esophageal carcinoma with SMARCA4 mutation is an overly aggressive disease, and further research on the affected molecular pathway may help improve its prognosis.

Mucosal impedance is a marker of esophageal mucosal integrity and a novel technique for assessing esophageal function and pathology. This article highlights its development and clinical application for gastroesophageal reflux disease (GERD), Barrett\'s esophagus, and eosinophilic esophagitis. A narrative review of key publications describing the development and use of mucosal impedance in clinical practice was conducted. A low mean nocturnal baseline impedance (MNBI) has been shown to be an independent predictor of response to anti-reflux therapy. MNBI predicts medication-responsive heartburn better than distal esophageal acid exposure time. Patients with equivocal evidence of GERD using conventional methods, with a low MNBI, had an improvement in symptoms following the initiation of PPI therapy compared to those with a normal MNBI. A similar trend was seen in a post fundoplication cohort. Strong clinical utility for the use of mucosal impedance in assessing eosinophilic esophagitis has been repeatedly demonstrated; however, there is minimal direction for application in Barrett\'s esophagus. The authors conclude that mucosal impedance has potential clinical utility for the assessment and diagnosis of GERD, particularly when conventional investigations have yielded equivocal results.

Esophageal pseudodiverticulosis, a rare condition, involves small sac-like structures in the esophageal wall, stemming from dilated excretory ducts of submucosal glands. While uncommon, it can complicate Candida albicans esophagitis, a yeast infection linked to various clinical issues, including pseudodiverticula formation. This unique association underscores the importance of understanding its clinical implications and optimal management. In this case, a 68-year-old female sought medical attention for dysphagia and recurrent food impaction. The diagnostic journey revealed esophageal pseudodiverticulosis and Candida albicans esophagitis, emphasizing the complexity of esophageal disorders.
