Abstract
Epidemiologic studies have suggested that obesity is associated with an increased risk of several cancers [1] such as colon and esophageal adenocarcinomas [2]. A positive association between body mass index (BMI) and gastric malignancies has only been described for adenocarcinomas of the gastric cardia, while the association between BMI and gastric noncardia adenocarcinoma is unclear [3]. A recent systematic review [4] analyzed all reported cases of esophageal or gastric cancers after several bariatric procedures, including vertical banded gastroplasty, gastric band, or Roux-en-Y gastric bypass; but only a case of a lower esophageal adenocarcinoma has been described in a patient who underwent a previous (4 months) sleeve gastrectomy (SG) [5].
