OBJECTIVES: To identify the associations of lymph node metastases (pN+), number of positive nodes, and pN subclassification with cancer, treatment, patient, geographic, and institutional variables, and to recommend extent of lymphadenectomy needed to accurately detect pN+ for esophageal cancer. SUMMARY BACKGROUND DATA: Limited data and traditional analytic techniques have precluded identifying intricate associations of pN+ with other cancer, treatment, and patient characteristics...

OBJECTIVE: This study was aimed to define the predictive values of preoperative Fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (F-18 FDG PET/CT) parameters and compared to define effective parameters for prediction of overall survival (OS) and recurrent free survival (RFS) in locally advanced esophageal cancer (LAEC). MATERIALS AND METHODS: This study included 44 patients with LAEC who received F-18 FDG PET/CT. Univariate and multivariate analyses were used to calculate survival, and the survival curves were estimated by clinical factors and F-18 FDG PET/CT-derived parameters...

BACKGROUND: Circumferential resection margins (CRM) for esophageal cancer (EC), defined by the College of American Pathologists (CAP; >0 mm) or the Royal College of Pathologists (RCP; >1 mm) as tumor-free (R0), are based on a surgery-alone approach. We evaluated the usefulness of both definitions in current practice with neoadjuvant chemoradiotherapy (nCRT). METHODS: CRMs were measured in 209 patients (104 with nCRT) with locally advanced EC after transthoracic esophagectomy...

IMPORTANCE: The prognostic role of the extent of lymphadenectomy during surgery for esophageal cancer is uncertain and requires clarification. OBJECTIVE: To clarify whether the number of removed lymph nodes influences mortality following surgery for esophageal cancer. DESIGN, SETTING, AND PARTICIPANTS: Conducted from January 1, 2000, to January 31, 2014, this was a cohort study of patients who underwent esophagectomy for cancer in 2000-2012 at a high-volume hospital for esophageal cancer surgery, with follow-up until 2014...

BACKGROUND: The Japan Clinical Oncology Group (JCOG) 9907 trial has changed the standard of care for advanced thoracic oesophageal cancer in Japan from postoperative chemotherapy to preoperative chemotherapy. The impact of preoperative chemotherapy on the risk of developing postoperative complications remains controversial. This article reports the safety analysis of JCOG9907, focusing on risk factors for postoperative complications. METHODS: Patients with potentially resectable advanced thoracic oesophageal squamous cell carcinoma were randomized to either postoperative or preoperative chemotherapy followed by transthoracic oesophagectomy with D2-3 lymphadenectomy...

INTRODUCTION: Premalignant lesions of the foregut (esophagus and stomach) are common entities usually incidentally identified on either endoscopic or radiographic imaging studies. SYMPTOMS: These lesions are often asymptomatic or associated with vague gastrointestinal symptoms. TREATMENT: Current management of benign and premalignant lesions of the foregut includes primarily ablative and resective endoscopic techniques as well as thoracoscopic, laparoscopic, and open surgical techniques of enucleation and segmental resections...

OBJECTIVE: To determine the difference in in-hospital mortality and length of hospital stay (LOS) after esophagectomy between the United States and England. BACKGROUND: Since 2001, complex procedures such as esophagectomy have been centralized in England, but in the United States no formal plan for centralization exists. METHODS: Patients who underwent esophagectomy for cancer between 2005 and 2010 were identified from the Nationwide Inpatient Sample (United States) and the Hospital Episodes Statistics (England)...

OBJECTIVE: To investigate the prognostic significance of lymphovascular invasion (LVI) in patients with esophageal squamous cell carcinoma (ESCC) treated with neoadjuvant chemoradiotherapy (nCRT). METHODS: We retrospectively reviewed the charts of 416 consecutive patients with ESCC who underwent surgical resection following nCRT at the Chang Gung Memorial Hospital between 1998 and 2008. After exclusion of patients with non-R0 resection or showing no residual tumor (ypT0Nx), the histological tumor sections of 231 patients were reviewed for LVI...

OBJECTIVE: Tyrosine kinase inhibitors (TKIs) of the epidermal growth factor receptor (EGFR) have been reported to be effective in the treatment of esophageal and esophagogastric junction cancers. The aim of this study was to detect the frequency of EGFR mutation and expression in Chinese patients with esophageal, esophagogastric junction and gastric cancers, and to clarify the value of EGFR mutation and expression in predicting the efficacy of TKI in the treatment of these tumors. METHODS: In this study, 180 tumor samples with histologically confirmed esophageal cancer (39 cases), cancer of the esophagogastric junction (92 cases) and gastric cancer (49 cases) were collected...

BACKGROUND: Endoscopic resection is increasingly used to treat localized, early-stage esophageal cancer. We sought to assess its adoption, characterize the risks of nodal metastases, and define differences in procedural mortality and 5-year survival between endoscopic and surgical resection in the United States. METHODS: From the National Cancer Data Base, patients with T1a and T1b lesions were identified. Treatment patterns were characterized, and hierarchical regression methods were used to define predictors and evaluate outcomes...
