title: [How can we make mass-screening of stomach cancer more efficient using epidemiological results?].
abstract: From an observation of personnel we expect epidemiological studies make mass-screening of stomach cancer more efficient and suppose they should be done as to following aspects: (1) To decide the most efficient interval of mass-screening, investigating the frequency distribution of "Saving Duration" on many stomach cancers that is the duration when a stomach cancer is both detectably by screening and curable. (2) To decide who should undergo stomach examination quantifying cancer-risks of individuals with the use of epidemiological results. (3) To make epidemiological studies more sensitive and useful, classifying stomach cancers by microscopic pathological type, macroscopic one or "Saving Duration". (4) To settle a statistical standard of epidemiological results which is demanded for them to be useful in mass-screening.
