Clinicopathologic features of esophageal neuroendocrine carcinoma (NEC), apart from those of small-cell carcinoma, have not been characterized. We evaluated the clinicopathologic features and prognosis including overall survival of NEC of the esophagus. We identified 40 patients with esophageal NEC from our institutional database. All cancers had been(More)
The NCCN Clinical Practice Guidelines in Oncology for Gastric Cancer provide evidence- and consensus-based recommendations for a multidisciplinary approach for the management of patients with gastric cancer. For patients with resectable locoregional cancer, the guidelines recommend gastrectomy with a D1+ or a modified D2 lymph node dissection (performed by(More)
INTRODUCTION Perioperative complications influence long- and short-term outcomes after esophagectomy. The absence of a standardized system for defining and recording complications and quality measures after esophageal resection has meant that there is wide variation in evaluating their impact on these outcomes. METHODS The Esophageal Complications(More)
Barrett's esophagus (BE)/Barrett's metaplasia (BM) is a recognized precursor of esophageal adenocarcinoma (EA) with an intermediary stage of dysplasia. The low yield and high cost of endoscopic screening of patients with BE underscores the need for novel biomarkers, such as microRNA (miRNA), which have emerged as important players in neoplastic progression(More)
BACKGROUND Local failure after definitive chemoradiation therapy for unresectable esophageal cancer remains problematic. Little is known about the failure pattern based on modern-day radiation treatment volumes. We hypothesized that most local failures would be within the gross tumor volume (GTV), where the bulk of the tumor burden resides. METHODS We(More)
Gastric cancer is a very challenging malignancy given that it presents late, has complex pathogenetic mechanisms with multiple carcinogenic processes implicated, and is only moderately sensitive to chemotherapy and radiation. Accurate staging for gastric cancer is possible with the availability of sophisticated imaging studies, endoscopic ultrasound, and(More)
BACKGROUND Postesophagectomy diaphragmatic hernia (PDH) is a recognized but severely under-reported and potentially hazardous event. Information regarding the natural course of this condition and guidelines regarding indications for reoperative intervention are lacking. In this study we aim to describe the frequency, predictors of incidence, and indications(More)
Superficially invasive esophageal adenocarcinomas are a heterogeneous group of tumors, including tumors invading into mucosa and submucosa. The prognostic significance of the depth of tumor invasion and lymph node status in this group of patients remain unclear. We evaluated 90 consecutive patients with resected T1 adenocarcinoma of esophagus or(More)
BACKGROUND The prognosis for patients with esophageal and esophagogastric junction (EGJ) adenocarcinoma remains poor, even after surgical resection. Pathologic assessment of depth of invasion and lymph node status are the primary prognostic factors in these patients. In patients with esophageal squamous cell carcinoma, increased epidermal growth factor(More)
PURPOSE Patients receiving cancer-related thoracotomy are highly symptomatic in the first weeks after surgery. This study examined whether at-home symptom monitoring plus feedback to clinicians about severe symptoms contributes to more effective postoperative symptom control. PATIENTS AND METHODS We enrolled 100 patients receiving thoracotomy for lung(More)
