Predicting preoperative occult peritoneal metastasis in colorectal cancer patients Cancer
Conditions
Interventions
All enrolled patients were initially diagnosed as PM-negative by CT readings, but later confirmed with the actual PM status during the laparoscopic exploration. The patients were divided into two coho
