[Squamous change in gastric cancer].
Squamous change was found at the rate of 4% in 3,727 operated patients with gastric adenocarcinoma. The incidence of squamous change was 0.47%, 4.2% and 5.6% in the early, pm-invasive and s-invasive cases, respectively. This phenomenon was considered to be secondary metaplastic change associated with the growth of the adenocarcinoma. Protuded type cancers were found in 63.5%, well-differentiated adenocarcinoma with moderate to marked intestinal metaplasia was found in 86.1%. The average patient age was 65.5, the male to female ratio was 2.3:1. Regarding cancer location, 19.6% were in the upper 1/3 of the stomach, especially adjacent to the esophago-cardiac junction.
