ctDNA in appendix cancer reveals new insights for prognosis and treatment
Appendiceal adenocarcinoma (AA), a rare type of appendix cancer, can be challenging to detect. While it is often treated with surgery and hyperthermic intraperitoneal chemotherapy (HIPEC), better tools are needed to guide patient selection, monitoring and treatment decisions. Researchers led by Michael White, M.D., and John Paul Shen, M.D., analyzed circulating tumor DNA (ctDNA) in AA and identified a unique mutational profile, with TP53mutations being the most common. They detected ctDNA less frequently in metastatic AA and at lower levels...
