Evaluation of early gastric cancer where evident lesions were undetected.

Abstract

In order to raise the accuracy among radiologists, cases where evident lesions were undetected were presented. For each case of diagnosed early gastric cancer by group exam, indirect fluororadiography taken each year up to three years before diagnosis was reviewed again. Among early gastric cancer cases diagnosed by group exam over five years from 2006 to 2010, 113 cases that received medical checkups at this facility from the time cancer was diagnosed until three years before, were determined as continuous examinations, and targeted for consideration. Cases where evident lesions were undetected were set as sample cases.
Results of the consideration showed that 19 (16.8%) out of 113 cases were indicative of cases where evident lesions were undetected. Cases at a higher rate were in the U area, in the posterior wall and in 0-I types.
