OBJECTIVE: The aim of this study was to assess the impact of chemoradiation on the immune microenvironment to influence and optimally design future neoadjuvant clinical trials. SUMMARY BACKGROUND DATA: Programmed death (PD)-1 inhibitors in metastatic gastroesophageal cancer have demonstrated response rates of approximately 25% in programmed death ligand-1 (PD-L1+) tumors. Unfortunately, the majority of patients do not respond. Therefore, a rationale strategy of combining immunotherapeutic agents with chemoradiation in earlier stage esophageal cancer may prevent metastatic disease in patients...

BACKGROUND AND AIM: Esophageal endoscopic submucosal dissection (ESD) to resect widespread lesions has increased the incidence of strictures, and some patients develop strictures despite receiving prophylactic locoregional triamcinolone injections. This study evaluated the predictive factors for esophageal stricture formation in patients administered prophylactic triamcinolone injections after ESD. METHODS: This was a retrospective observational study. Of 552 consecutive patients who underwent ESD, those who received prophylactic triamcinolone injections immediately after ESD were enrolled...

Progestin and adipoQ receptor family member 3 (PAQR3) has exhibited anticancer activity in multiple malignancies. However, its expression and function in esophageal squamous cell carcinoma (ESCC) is still elusive. In this work, we examined the expression of PAQR3 in 40 surgically resected ESCC specimens and their adjacent normal tissues. The expression of PAQR3 in ESCC cell lines was measured after treatment with the demethylating agent 5-aza-2'-deoxycytidine (5-Aza-CdR). The effects of overexpression of PAQR3 on cell proliferation, colony formation, invasion, and tumorigenesis were investigated...

OBJECTIVE: To define "best possible" outcomes in total minimally invasive transthoracic esophagectomy (ttMIE). BACKGROUND: TtMIE, performed by experts in patients with low comorbidity, may serve as a benchmark procedure for esophagectomy. PATIENTS AND METHODS: From a cohort of 1057 ttMIE, performed over a 5-year period in 13 high-volume centers for esophageal surgery, we selected a study group of 334 patients (31.6%) that fulfilled criteria of low comorbidity (American Society of Anesthesiologists score ≤2, WHO/ECOG score ≤1, age ≤65 years, body mass index 19-29 kg/m)...

BACKGROUND AND STUDY AIMS : Accurate endoscopic detection of dysplasia in patients with Barrett's esophagus (BE) remains a major clinical challenge. The current standard is to take multiple biopsies under endoscopic image guidance, but this leaves the majority of the tissue unsampled, leading to significant risk of missing dysplasia. Furthermore, determining whether there is submucosal invasion is essential for proper staging. Hence, there is a clinical need for a rapid in vivo wide-field imaging method to identify dysplasia in BE, with the capability of imaging beyond the mucosal layer...

BACKGROUND AND STUDY AIMS : Cervical esophageal cancer (CEC) is a less common form of cancer and often locally advanced at the time of diagnosis; thus, survival rates for patients with CEC remain poor. However, no reports exist on results of endoscopic submucosal dissection (ESD) for superficial cancer at the cervical esophagus. The aim of this retrospective study was to elucidate the clinicopathological features and clinical outcomes of ESD for superficial CEC. PATIENTS AND METHODS:  ESD was performed on 891 lesions (in 662 patients) for superficial esophageal cancer from January 2008 to December 2015...

CONTEXT: - In advanced gastric, esophageal, and gastroesophageal junction adenocarcinomas (GE-GEJ-AC) that overexpress ERBB2 (erb-b2 receptor tyrosine kinase 2 or HER2), anti-HER2 monoclonal antibody therapy confers survival benefit. To select patients for treatment, HER2 expression and gene amplification are evaluated by immunohistochemistry (IHC) and in situ hybridization. OBJECTIVE: - To determine whether GE-GEJ-AC tested for HER2 on biopsy specimens of a primary tumor show different IHC scores and/or HER2 amplification by in situ hybridization in matched resection specimens, potentially changing therapy eligibility...

BACKGROUND AND AIMS: Subepithelial esophageal tumors (SETs) are frequent incidental findings. Although symptomatic tumors are surgically or endoscopically resected, there is no consensus on the management of asymptomatic esophageal leiomyomas. METHODS: Appropriate ICD-9 codes followed by medical record review were used to identify patients with SETs from January 1992 to March 2017, with abstraction of basic demographics, surveillance intervals, and mortality. Patients were contacted to complete a phone questionnaire to assess follow-up and complete the validated brief esophageal dysphagia questionnaire (BEDQ)...

Esophageal cancer is the eighth most common malignant tumor worldwide, and the number of incidences of esophageal adenocarcinoma is increasing in the Western world. Despite improvements in perioperative treatment, the overall survival rate of patients with esophageal adenocarcinoma remains poor. Breast cancer type 1 susceptibility protein (BRCA1)-associated protein (BAP1) is located on chromosome 3p21, and it is an enzyme with ubiquitin carboxyl hydrolase activity that regulates cell growth. It interacts with BRCA1, and the nuclear localization of BAP1 is required for its tumor suppressor function...

BACKGROUND: Standard treatment for locally advanced esophageal cancer includes neoadjuvant therapy followed by surgical resection. However, many patients experience a period of decreased oral intake during neoadjuvant treatment and are at risk for malnutrition. We hypothesize that use of jejunostomy tube (j-tube) feedings during neoadjuvant therapy in selected patients may be associated with better perioperative outcomes. METHODS: A prospectively collected database at a single institution was retrospectively analyzed...

Neoadjuvant therapy is increasingly used to treat patients with a wide variety of malignancies. Histologic evaluation of treated specimens provides important prognostic information and may guide subsequent chemotherapy. Neoadjuvant therapy is commonly employed in the treatment of locally advanced rectal adenocarcinoma, hepatic colorectal metastases, esophageal/esophagogastric junction carcinoma, and pancreatic ductal adenocarcinoma. Numerous tumor regression schemes have been used in these tumors and standardized approaches to evaluate these specimens are needed...

OBJECTIVES: The reported 1- and 3-year overall survival rates after esophagectomy for stage I superficial esophageal squamous cell carcinoma (SESCC) are 95-97% and 86%, and those after definitive chemoradiotherapy (CRT) are 98% and 89%, respectively. This study was performed to elucidate the efficacy and safety of another treatment option for SESCC: endoscopic resection (ER) followed by CRT. METHODS: We retrospectively reviewed the overall survival, recurrence, and grade ≥3 adverse events of consecutive patients who refused esophagectomy and underwent ER followed by CRT for SESCC from 1 January 2006 to 31 December 2012...

BACKGROUND: PET-CT is widely used for both the staging and planning of primary or neoadjuvant chemoradiotherapy for esophageal cancer. Inclusion of PET-CT information into radiotherapy planning often leads to substantial modifications of the target volume. In the case of detection of distant metastases, it may also result in a switch to a palliative treatment approach. This spares patients from therapy-related toxicities that provide no clinical benefit. However, due to a lack of studies, it is currently unclear whether the advantages of PET-CT also translate into a measurable improvement in patient survival...

I Gockel, C Wittekind
The microscopic identification of residual tumor tissue in the oral or aboral resection margins (R1 resection) of esophageal specimens following oncologic esophageal resection, increases the risk of tumor recurrence and disease-related morbidity. Esophageal resection with its associated risks is only meaningful, if an R0 situation can be safely achieved. The relevance of microscopic involvement of the circumferential resection margin (CRM) in esophageal carcinoma in its different definitions by the British and the American Societies of Pathology has up to now never been investigated in a prospective study...

There has been an alarming rise in the incidence of esophageal adenocarcinoma which continues to have poor survival rates primarily due to lack of effective chemotherapy and presentation at advanced stages. Over a dozen chemotherapeutic agents are FDA approved for esophageal cancer (EC), and a two or three-drug combination is typically prescribed as first-line therapy for the majority of EC patients, administered either pre or post-operatively with esophageal resection. We have noticed significant variability in adjuvant and neoadjuvant regimens used in the community setting...

BACKGROUND: Accurate intraoperative localization of esophageal lesions is essential for successful surgical resection. We tested whether preoperative endoscopic placement of titanium clips could facilitate intraoperative localization of early-stage esophageal cancer or severe dysplasia. METHODS: A prospective randomized clinical trial was performed between May 2012 and July 2014. All enrolled patients received preoperative endoscopy and esophageal endoscopic ultrasound, as well as pathological study on the biopsy specimen, to confirm early stage esophageal cancer or severe dysplasia...
