Cigarette and alcohol use in patients with adenocarcinoma of the gastric cardia or lower esophagus.
The authors studied the cigarette and alcohol use of 243 patients with adenocarcinoma of the cardia or lower esophagus, including 66 with Barrett's metaplasia (esophagocardia group). They compared results of that investigation with the cigarette and alcohol use of 303 patients with squamous carcinoma of the esophagus, a cancer in which an etiologic association is proven, and of 338 patients with stomach cancer not involving the cardia, a cancer in which there is little or no association with cigarettes or alcohol. Controlled for other variables, patients with squamous cancer used more cigarettes and alcohol than the other two groups. There was no significant difference in cigarette or alcohol use between patients with esophagocardia and stomach cancer or between those in the esophagocardia group with or without Barrett's metaplasia. Because cigarette and alcohol use was not greater in patients with esophagocardia than in those with stomach cancer, the authors do not think that such factors explain the increasing incidence of adenocarcinoma of the cardia or lower esophagus.
