This study selected cases of colorectal cancer liver metastasis patients who underwent liver metastasis tumor resection, retrieved the pathological HE sections of the metastatic lesions, and constructed a predictive model. AI software was applied to delineate different types of regions, achieving full automation of HGP prediction and constructing a predictive model. Statistical analysis was conducted on the classification of histopathological growth patterns (HGP) of liver metastasis and the survival prognosis of patients, and the differences in prognosis among different HGP classification methods were compared. This provides a new method for judging prognosis and treatment for clinical treatment of colorectal cancer liver metastasis patients.

Inclusion Criteria:

• Patients with colorectal cancer liver metastases who underwent resection of liver metastases;
• Confirmed by a pathologist as having liver metastases from colorectal cancer;

Exclusion Criteria:

• Cases of colorectal cancer liver metastasis that cannot be classified by histopathology.

Patients must meet all inclusion and exclusion criteria. In addition, the patient should be thoroughly informed about the study, including the study visit schedule and required evaluations and all regulatory requirements for informed consent. The written informed consent should be obtained from the patient prior toenrollment. The following criteria apply to all patients enrolled onto the study unless otherwise specified.
