Hepatic Arteriography and C-Arm CT-Guided Ablation (HepACAGA) to Improve Tumor Visualization, Navigation and Margin Confirmation in Percutaneous Liver Tumor Ablation.
Cardiovasc Intervent Radiol
October 2023
Purpose: We present a technique that combines Hepatic Arteriography with C-arm CT-Guided Ablation (HepACAGA) to improve tumor visualization, navigation and margin confirmation for percutaneous ablation of liver tumors.
Materials And Methods: All consecutive patients scheduled for HepACAGA between April 20th, 2021, and November 2nd, 2021, were included in this retrospective, cohort study. HepACAGA was performed in an angiography-suite under general anesthesia.
Article Synopsis
- Organoid technology offers a promising approach for precision medicine by assessing drug sensitivity of individual patient tumors in the lab, potentially simplifying traditional complex profiling methods.
- The SENSOR trial tested the feasibility of using patient-derived organoids to guide treatment decisions for patients who had not responded to standard care, involving drug screening on organoid cultures.
- Despite generating significant responses in organoid cultures, the treatments derived from these results did not yield objective clinical benefits for the patients, highlighting limitations in the technology's current application.
Background: Combining resection and thermal ablation can improve short-term postoperative outcomes in patients with colorectal liver metastases (CRLM). This study assessed nationwide hospital variation and short-term postoperative outcomes after combined resection and ablation.
Methods: In this population-based study, all CRLM patients who underwent resection in the Netherlands between 2014 and 2018 were included.
The guidelines for metastatic colorectal cancer crudely state that the best local treatment should be selected from a 'toolbox' of techniques according to patient- and treatment-related factors. We created an interdisciplinary, consensus-based algorithm with specific resectability and ablatability criteria for the treatment of colorectal liver metastases (CRLM). To pursue consensus, members of the multidisciplinary COLLISION and COLDFIRE trial expert panel employed the RAND appropriateness method (RAM).

Methods: A retrospective multicenter study was performed in patients with a cT1 renal mass treated with ablation between January 2007 and July 2019, including a search in the national pathology database for patients with a RMB planned for ablation. Patient and tumor characteristics and information on malignant, benign, and non-diagnostic biopsy results were collected to establish rates of overtreatment and number of ablations avoided in case of benign or non-diagnostic histology.
