Elevated Angiogenic Factor Levels After Transarterial Radioembolization for Colorectal Cancer Liver Metastases May...

Area of Science:

• Oncology
• Interventional Radiology
• Biomarkers

Background:

• Colorectal cancer liver metastases (CRCLMs) are a significant clinical challenge.
• Transarterial radioembolization (TARE) is a treatment option for CRCLMs.
• Angiogenic factors play a role in tumor growth and metastasis.

Purpose of the Study:

• To investigate changes in circulating angiogenic factor levels post-TARE for CRCLMs.
• To determine the prognostic value of these angiogenic factor changes.

Main Methods:

• Blood samples were collected from 23 patients before and at 1 day, 1 week, and 6 weeks after TARE.
• Serum levels of angiogenic factors, including basic fibroblast growth factor, platelet-derived growth factor, and vascular endothelial growth factor (VEGF), were analyzed.

Main Results:

• Elevated serum levels of basic fibroblast growth factor and platelet-derived growth factor at 1 week post-TARE were associated with shorter overall survival (OS).
• Elevated serum VEGF levels at 6 weeks post-TARE were also linked to significantly shorter OS times.
• Early increases in angiogenic factors and VEGF at 6 weeks correlated with reduced OS and progression-free survival.

Conclusions:

• Post-TARE changes in serum angiogenic factor levels, particularly VEGF, hold prognostic significance for CRCLMs.
• Monitoring angiogenic factors after TARE may help predict patient outcomes and inform treatment strategies.
