Eligibility
Inclusion criteria
Inclusion criteria: This study includes patients with colorectal liver metastases (CLM) diagnosed as disappearing liver metastases (DLM) before surgery among those who underwent hepatic resection after preoperative chemotherapy during the study period. The study comprises a prospective cohort and a retrospective cohort. Patients scheduled for hepatic resection of CLM, including DLM, will be enrolled in the prospective cohort. Patients who had already undergone hepatic resection for CLM, including DLM, prior to the start of the study will be included in the retrospective cohort. The retrospective cohort will target cases from the past two years.
Exclusion criteria
Exclusion criteria: 1. Patients under 20 years of age at the time of consent acquisition. 2. Cases where contrast-enhanced CT or MRI was not feasible. 3. Patients deemed unfit for surgery based on their overall condition. 4. Cases with more than 50 liver metastases prior to treatment, as accurately counting them was deemed impractical. 5. Other cases deemed unsuitable as study subjects by the principal investigator.
