FAT atypical cadherin 1 (FAT1) belongs to the cadherin superfamily and has been reported to regulate cell‑cell adhesion and other cell behaviors, suggesting its pivotal roles in human cancers. We previously identified FAT1 as one of the significant mutant genes in esophageal squamous cell carcinoma (ESCC). In the present study, the knockdown of FAT1 expression in YSE2 and Colo680N cell lines was carried out by lentivirus, and we found that knockdown of FAT1 led to acceleration of cell migration and invasion...

Gastroesophageal (GE) cancers continue to be a significant cause of mortality globally. Despite therapeutic advances in oncology, the prognosis of advanced GE cancer remains exceedingly poor. Immunotherapy has caused a major paradigm shift in the field of oncology. Not all patients benefit from these agents and several studies are trying to identify predictive and prognostic biomarkers to better inform and guide treatment decisions. The potential role of immunotherapy in GE cancers is emerging. These cancer types are molecularly and immunologically heterogeneous, and this heterogeneity influences the tumor microenvironment posing a significant challenge to studying biomarkers of response to immunotherapy...

Background: The relationship of complete pathologic response (cPR) with the timing of esophagectomy after neoadjuvant chemoradiation (nCRT) is not well defined. We sought to determine if a delay in esophagectomy after nCRT would result in increased likelihood of cPR and improved survival. Methods: This is a retrospective analysis of a prospectively maintained database of all patients treated with nCRT and esophagectomy between 2004 and 2014. Patients were divided into two groups based on timing of esophagectomy (≤50 vs ...

Since the preclinical results about chimpanzee adenovirus serotype-68 (AdC68)-based vaccine showed an encouraging results, it reminded us that AdC68 may be a suitable cancer vaccine vector. Previous study indicated that the seroprevalence of neutralizing antibodies (NAbs) against adenovirus was different between cancer patients and healthy volunteers. Knowledge regarding the prevalence rates of AdC68 NAbs for cancer patients is lacking. Therefore, assessing the preexistence of NAbs against AdC68 in cancer patients could provide useful insights for developing future AdC68-based cancer vaccines...

Purpose: IκB kinase epsilon (IKBKE; IKKε), a member of the nuclear factor-κB kinase inhibitor family, is upregulated in several human cancers, including breast cancer, prostate cancer, and ovarian cancer. Esophageal squamous cell carcinoma (ESCC) is one of the most common and most aggressively malignant cancers with dismal prognosis. However, the state of IKBKE expression in ESCC is still unknown and its potential value remains unexplored. Patients and methods: IKBKE protein expression was evaluated by immunohistochemistry in 118 paraffin specimens of ESCC treated by curative surgery...

AIM: To investigate post endoscopic submucosal dissection electrocoagulation syndrome (PEECS) of the esophagus. METHODS: We analyzed 55 consecutive cases with esophageal endoscopic submucosal dissection for superficial esophageal squamous neoplasms at a tertiary referral hospital in South Korea. Esophageal PEECS was defined as "mild" meeting one of the following criteria without any obvious perforation: fever (≥ 37.8 °C), leukocytosis (> 10800 cells/μL), or regional chest pain more than 5/10 points as rated on a numeric pain intensity scale...

Tracheoesophageal voice puncture (TEP) coupled with the use of voice prosthesis has been considered as the gold standard for speech rehabilitation in patients of advanced laryngeal/hypopharyngeal carcinomas, who have undergone a total laryngectomy with or without partial pharyngectomy. Although prosthetic voice rehabilitation is commonly practiced worldwide including India, there is a paucity of published Indian data, more so in the current era of organ conservation. This study included 60 laryngectomized patients with a prosthetic voice rehabilitation at a tertiary cancer center in South India between January 1, 2010 and December 31, 2013...

Aberrant expression of the secretory protein Dickkopf1 (DKK1) is associated with poor prognosis of esophageal squamous cell carcinoma (ESCC), but the underlying mechanism of how DKK1 is involved in aggressiveness of ESCC is not clear. In this study, we show that cytoskeleton-associated protein 4 (CKAP4) functions as a DKK1 receptor in ESCC cells. Immunohistochemical analyses of ESCC revealed that both DKK1 and CKAP4 are minimally expressed in associated normal esophageal squamous mucosa of non-tumor regions, but strongly expressed in tumor lesions...

BACKGROUND: Myeloid-derived suppressor cells (MDSCs) are a population of immature immune cells with several protumorigenic functions. CD38 is a transmembrane receptor-ectoenzyme expressed by MDSCs in murine models of esophageal cancer. We hypothesized that CD38 could be expressed on MDSCs in human colorectal cancer (CRC), which might allow for a new perspective on therapeutic targeting of human MDSCs with anti-CD38 monoclonal antibodies in this cancer. METHODS: Blood samples were collected from 41 CRC patients and 8 healthy donors, followed by peripheral blood mononuclear cell (PBMC) separation...

We aimed to estimate for the first time the burden of fungal infections in Uruguay. Data on population characteristics and underlying conditions were extracted from the National Statistics Institute, the World Bank, national registries, and published articles. When no data existed, risk populations were used to estimate frequencies extrapolating from the literature. Population structure (inhabitants): total 3,444,006; 73% adults; 35% women younger than 50 years. Size of populations at risk (total cases per year): HIV infected 12,000; acute myeloid leukemia 126; hematopoietic stem cell transplantation 30; solid organ transplants 134; COPD 272,006; asthma in adults 223,431; cystic fibrosis in adults 48; tuberculosis 613; lung cancer 1400...
