title: Esophageal cancer and diet--a case-control study.
abstract: It has been estimated that approximately 40% of human cancers may be associated with dietary factors. The relationship is more significant in esophageal cancers. Case-control studies involving 35 subjects of early-diagnosed esophageal cancers showed low mean blood levels of retinol, zinc (p less than 0.001), folic acid (p less than 0.01), and albumin (p less than 0.05). Relative risk was significantly higher for low levels of retinol and zinc. Diet, in general, in both groups reflected poor intake of several nutrients.
