Predictive nomogram of the risk of peritoneal relapse following radical gastric cancer surgery

Abstract

Background: Peritoneal relapse (PR) is the most common pattern of gastric cancer (GC) recurrence after radical treatment. Currently, a variety of adjuvant intraperitoneal chemotherapy methods are being tested for their efficacy in reducing the level of PR. The investigation of prospective predictors of metachronous peritoneal metastases enables us to develop a predictive nomogram of peritoneal relapse risk of GC after radical surgery, which is crucial in surgical oncology today. Such a nomogram will allow clinicians to easily and quickly identify a group of patients who require adjuvant intraperitoneal chemotherapy.
