About

The goal of this clinical trial is to learn about Fruquintinib combined with Adebrelimab and high and low dose radiotherapy in the treatment of second-line and above failure MSS(microsatellite stability) metastatic colorectal cancer.

The main question it aims to answer is: The efficacy and safety of Fruquintinib combined with Adebrelimab and high and low dose radiotherapy in the third line and beyond treatment of MSS metastatic colorectal cancer.

Participants will receive the combination of Fruquintinib and Adebrelimab within 3 weeks after completion of high and low dose radiotherapy on metastases until disease progression or intolerable toxicity occurred.
