About This Trial
ECDNA is almost non-existent in normal cells, but exists in nearly half of human cancer cells, indicating that studying such abnormal DNA is of great significance for our understanding of tumor formation and evolution. The changes in ecDNA expression in intestinal type gastric cancer may be closely related to the occurrence and development of gastric cancer. Dynamic monitoring of changes in ecDNA …
