胃癌診断におけるルーチン検査の確かさ―X線検査からみて

Accuracy of Routine Radiography of the Diagnosis of Gastric Cancer

要旨　非紹介切除胃癌134例に対するX線診断の実状を調査し，胃癌診断におけるルーチンX線検査の確かさの一面に触れてみた．X線検査先行胃癌は80例で，内視鏡検査先行胃癌は54例であった．ルーチンX線検査では11mm以上の大きさの早期癌を発見できたものの，60mm以上の大きさの早期癌を発見できなかった．X線検査と内視鏡検査の有検査歴癌を比較すると，A領域の20mm以下の早期癌にX線検査歴のある例が多かった以外には，特にこれといった差は指摘できなかった．ルーチンX線検査の質を高く，一定に保つためには，検査医の合理的配分について再考する必要がある．

　Authors researched on the actual state of radiography for 134 cases with gastric cancer, non-referred and resectable, and touched on one aspect of the accuracy of routine radiography for the diagnosis of gastric cancer.

　Gastric cancers detected by radiography intially were 80 cases and those detected by endoscopy initially were 54 cases. By routine radiography, it was possible to detect early gastric cancer more than 11 mm in size, but none of those more than 60 mm in size.

　Location and morphological characteristics of gastric cancers detected by radiography and endoscopy were evaluated but we were not able to point out particular differences, except that early gastric cancers under 20 mm in size in A‐area of AMC classification were detected mostly by endoscopy. It was found necessary to reconsider the rational distribution of examiners, in order to maintain high quality in examination by routine radiography.
