| pubmed-article:8470302 | pubmed:abstractText | There were 41 cases of esophageal cancer over a 7 years period in the State of Qatar. Qataris accounted for 30 (73.17%) of these cases while representing about 38% of the entire population. Also there is a slight preponderance of female cases especially among Qataris. Nutritional factors, dietary preferences, environmental factors, social status and habits as well as genetic factors may constitute important etiologic factors in the genesis of esophageal cancer in Qatar. | lld:pubmed |
