Hepatic Arterial Infusion With Floxuridine and Dexamethasone Combination With Chemotherapy With/Without Bevacizumab for Hepatic Metastases From Colorectal Cancer

The purpose of this study is to determine whether the addition of bevacizumab, to hepatic arterial therapy with floxuridine (FUDR) and dexamethasone (Dex) (regional chemotherapy), and either oxaliplatin or CPT-11, plus 5-fluorouracil and leucovorin (systemic chemotherapy) will increase disease free survival in patients who have undergone liver resection. The patient will be randomized (a computer generated decision as in the flip of a coin) to receive, or not to receive bevacizumab in addition to regional and systemic chemotherapy.

Therapeutic Efficacy and Safety of Ultrasound-Guided Microwave Ablation for Hepatic Metastatic Nodules

The liver is one of the most common organs where cancer cells spread (metastasize) from other parts of the body, especially from gastrointestinal cancers such as colorectal cancer. While surgical removal of liver tumors has traditionally been the standard treatment, most patients are not candidates for surgery due to tumor location, number of lesions, or underlying liver function. For these individuals, minimally invasive local therapies such as microwave ablation (MWA) provide an alternative approach to eradicate tumor tissue while preserving healthy liver parenchyma. Microwave ablation delivers localized high-frequency electromagnetic energy through a thin needle antenna placed percutaneously into the liver tumor. The generated heat induces rapid coagulative necrosis, destroying cancer cells within the target area. In this study, real-time ultrasound combined with CT image-fusion navigation is used to precisely position the ablation antenna within each nodule. The primary purpose of this study is to assess the therapeutic efficacy and safety of ultrasound-guided percutaneous microwave ablation for patients with liver metastases. Participants receive microwave ablation for their target liver tumors and are evaluated with contrast-enhanced CT or MRI at 1 month post-procedure to determine the rate of complete tumor ablation. Patients are then monitored longitudinally at 3, 6, 9, and 12 months to evaluate safety and check for local tumor recurrence.

Comprehensive Genomic Profiling of Colorectal Cancer Patients With Isolated Liver Metastases to Understand Response & Resistance to Cancer Therapy

This is a prospective study investigating the disease course of patients with colorectal cancer that have had their cancer spread to their liver. The aim of this study is find potential biomarkers for disease recurrence and therapeutic targets for prognostic information.
