Background/aims: Endoscopic resection has become the preferred treatment approach for select early esophageal adenocarcinoma (EAC); however, the epidemiology of early stage disease has not been well defined.

Methods: Surveillance Epidemiology and End Results (SEER) data were analyzed to determine age-adjusted incidence rates among major epithelial carcinomas, including EAC, from 1973 to 2017. The percent change in incidence over time was compared according to tumor subtype.

Introduction: The incidence, survival, and propensity for nodal metastasis in early-stage gastric signet ring cell carcinoma have not been defined in the United States. These data are critical determinants for treatment allocation.

Methods: Cases of gastric signet ring cell carcinoma were extracted from the national SEER database for the years 2004-2013.

Background And Study Aims: Localized approaches are being increasingly used in the management of early gastric adenocarcinoma; however, there are limited data on lymph node metastasis in the US population. This study examined the incidence and predictors of lymph node involvement for early-stage gastric adenocarcinomas in the USA.

Patients And Methods: Data were abstracted from the national SEER database from 2004 to 2013.

Background: In considering treatment allocation for patients with early esophageal adenocarcinoma, the incidence of lymph node metastasis is a critical determinant; however, this has not been well defined or stratified by the relevant clinical predictors of lymph node spread.

Methods: Data from the Surveillance, Epidemiology, and End Results database of the National Cancer Institute were abstracted from 2004 to 2010 for patients with early-stage esophageal adenocarcinoma. The incidence of lymph node involvement for patients with Tis, T1a, and T1b tumors was examined and was stratified by predictors of spread.
