Esophageal cancer with endemic distribution of high-risk areas in the world is also known to be more prevalent in the male--and in the aged-populations than in their counterparts. The hormonal characteristics of esophageal cancer patients and the geographical distribution of high and low-risk areas in Japan were comparatively investigated in search of the etiology of this neoplasia. A case-control study of 14 urinary steroids indicated that cancer patients of both sexes were associated with an acceleration of cortisone to hydrocortisone conversion within their bodies. Evidence was presented to suggest that the above state of glucocorticoid excess could be related to the production of hyperplasia as well as malignant transformation in the epithelial cells of the esophagus. The 10 highest risk areas and the 7 lowest risk areas were clearly separated by the 2 fault lines of the Japan Islands, a finding to suggest that some microelements of the soil play a role in conditioning the cancer risk. The possible linkage of the observed hormonal characteristics of Japanese patients to both the geochemistry of the soil and the genesis of this neoplasia is discussed in the light of the competitive relationship between the intake of vitamin C and endogenous nitrosation.
