Oesophageal and gastric carcinoma in the Republic of Yemen.

We conducted a preliminary survey on 3064 patients who underwent upper gastrointestinal endoscopy at the Al-Thawra Hospital in Sana'a, Republic of Yemen, between January and December 1991. The age/sex distribution, demographic features and social habits with respect to cigarette and water-pipe smoking and Qat chewing were compared for patients with oesophageal and gastric cancers (n = 183). A preponderance of women with carcinoma of the mid-oesophageal was noted, previously only recorded in areas of high prevalence.
