Recently a number of refined techniques such as X-ray examination, endoscopic study, and biopsy under direct observation are available for the diagnosis of early gastric cancer.
Althongh the combination or either one of those techniques is essential for the diagnosis of early carly cancer, it is not possible to use such techniques in a social wide screening and a more simple technique is desired at the preaent time. Our present attempt was thus forcuseb to find out which one of laboratory tests commonly used coulb be used for the substituatin of such refined techniques.
Laboratory tests used here were Shichi jos reaction, acidity in the stomach juice, anemia, decrease of body weight, occult blood in the feces, red blood cell sedimention rate, and subjective complaints.
Analysis of these laboratory findings in combination with above mentioned refinined techniques has indicated that anacidity and positive reaction of Shichijos reaction are relatively reliable tools for suspecting early cancer of the stomach.
Abnormalities in other 5 laboratory tests, however, have no relation to the occurrence of early stomach cancer.
It is suggested that abnormality in Shichijo s reaction and anacidity might de highly suggestve findings for detecting early cancer of the stomach.
