[Determination of the oral side safety margin in the resection of a Borrmann 4 type gastric cancer].
The oral margins of Borrmann 4 type gastric cancers have been examined, and it was found that the contraction rate of the stomach was 21% from tissue preparations that were made from fresh resected specimens. Further, the widest difference between the macroscopic and microscopic safety margin distance was 35 mm in the cases that were examined. The edge of cancer invasion into the oral side was found to be located under the mucosa in these cases and the mean distance of the safety margin was 13 mm, which was determined on performing a curative resection without a thoracotomy. From these results it has been deemed necessary to leave a safety margin of approximately 5 cm measured from the macroscopic invasion into the oral side.
