The yield of endoscopy and double contrast radiography for the detection of early gastric cancer in Malmö.

To evaluate the efficacy of endoscopy and double contrast radiography for the diagnosis of early gastric cancer we compared two three-year materials of all gastric cancers detected in Malmö before and after these diagnostic tools were introduced. Despite a high diagnostic potential of these methods they have not significantly increased the detection of early gastric cancer in Malmö. Evidently the selection of the patients is unsatisfactory and modifications of the indications for these examinations are discussed.
