Management Strategies for Disappearing Colorectal Liver Metastases After Systemic Chemotherapy: Long‐Term Outcomes and Preoperative Prediction of ‘True Complete Response’

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
ABSTRACT Background Determining whether to resect disappearing liver metastases (DLMs) after chemotherapy for colorectal liver metastases (CRLMs) remains challenging. Methods Patients who underwent hepatectomy after systemic chemotherapy for initially unresectable CRLMs were reviewed. True complete response (CR) was defined as either resected DLMs with
