RESPONSE: Re: Cancer of the Oral Cavity and Pharynx in Nonsmokers Who Drink Alcohol and in Nondrinkers Who Smoke Tobacco

Abstract
We thank Drs. Castellsagué and Muñoz for their interest in our work ( 1 ) and take this opportunity for reconsidering, as they have done, the risk of esophageal cancer in nonsmokers who drink alcohol and alcohol abstainers who smoke tobacco; we use the combined dataset of two case-control studies on esophageal cancer conducted in the greater Milan area ( 2 - 4 ) and the Pordenone province ( 5 ) of northern Italy.
