英文摘要: Abstract(#br) Background(#br)Next-generation sequencing (NGS) is a useful tool for detecting genomic alterations in circulating tumor DNA (ctDNA). To date, most ctDNA tests have been performed on patients with widely metastatic disease. Patients with peritoneal carcinomatosis (metastases) present unique prognostic and therapeutic challenges. We therefore explored preoperative ctDNA in patients with peritoneal metastases undergoing surgery.(#br) Methods(#br)Patients referred for surgical resection of peritoneal metastases underwent preoperative blood-derived ctDNA analysis (clinical-grade NGS [68–73 genes]). ctDNA was quantified as the percentage of altered circulating cell-free DNA (% cfDNA).(#br) Results(#br)Eighty patients had ctDNA testing: 46 (57.5%) women; median age 55.5 years. The...
