It will also learn about the safety of radiofrequency ablation. The main questions it aims to answer are:\n\nIs radiofrequency ablation safe and effective in the treatment of recurrent colorectal cancer liver metastases? What medical problems do participants have when treating with radiofrequency ablation? Does radiofrequency ablation enable patients with recurrent colorectal cancer liver metastases to live longer? Researchers will compare systemic therapy combined with radiofrequency ablation to systemic therapy to see if radiofrequency ablation works to treat liver metastases better.\n\nParticipants will:\n\nReceive systemic treatment for colorectal cancer liver metastases. Undergo (or not) radiofrequency ablation for colorectal cancer liver metastases.\n\nVisit the hospital once every 3 months for checkups and tests.",[57,58],"Colo-rectal Cancer","Liver Metastasis",[60,58,61],"Colo-rectal cancer","radiofrequency ablation","NOT_YET_RECRUITING","2024-09-25",{"date":65,"type":66},"2024-09-27","ACTUAL",{"date":68,"type":51},"2024-10",{"date":70,"type":51},"2026-12",{"name":5,"class":6}]
