Brief Summary
The aim of this observational study was to understand the prognostic imaging of the degree of intratumoral fibrosis and intratumoral α-SMA levels in patients with intrahepatic cholangiocarcinoma (ICC). The main questions it aims to answer are: Whether the degree of intratumoral fibrosis and the level of intratumoral α-SMA affect the overall survival and progression-free survival of ICC patients. Participants will be surveyed for survival and tumor recurrence up to 5 years after surgery.

Outcome Measures
Primary Outcomes (1)
Treatment Effects
5-year overall survival (OS)
From the time of the patient's surgery to the end of the 5-year follow-up
Study Arms (4)
intratumoral high-fibrosis group
intratumoral low-fibrosis group
α-SMA high-expression group
α-SMA low-expression
Interventions
Only the degree of intratumoral fibrosis and the expression of α-SMA in the postoperative pathological specimens of ICC patients were observed, without intervention measures.
Eligibility Criteria
Patients with single ICC who underwent radical partial hepatectomy in our hospital from January 2018 to January 2024 were retrospectively enrolled in this study.
You may qualify if:
- Patients who underwent radical resection of liver tumors in our center and obtained surgical specimens;
- ICC was diagnosed by postoperative pathology
You may not qualify if:
- Patients had received radiotherapy, chemotherapy, intervention and other treatments for liver tumors before surgery
- The tumor sections could not be obtained due to the loss of wax blocks or most of the defects of pathological specimens
- No upper abdominal Gd-EOB-DTPA-enhanced MRI examination in our center within one month before surgery
- Poor image quality or incomplete image data
