Spots Global Cancer Trial Database for Evaluation of the Efficacy of Two Guidance Techniques (Standard Injected CT vs Porto-scanner With Angio-CT) for Thermoablation Treatment of Colorectal Cancer Liver Metastases

Study Description

Brief Summary: Hepatic metastases of colorectal cancer (CRC) are partially necrotic tumors mainly vascularized by the hepatic artery. When resectable, these metastases must be removed with a safety margin of 1 mm. Resection margins greater than 1 cm are associated with better disease-free survival and no local recurrence. Thermoablation systems allow for ablation zones of approximately 4.5-5 cm in diameter. For tumors \<3 cm, subject to perfect targeting, it is possible to obtain ablation margins of 1 cm, which would greatly reduce the local recurrence rate. Accurate assessment of these tumor boundaries and characterization of these margins are paramount to ensure complete ablation. Thermoablation for these small liver metastases (\<3cm) has shown equivalent efficacy to surgery in terms of recurrence and survival with fewer complications. Thermoablation treatment is indicated for patients with stable disease undergoing chemotherapy. This leads to liver remodeling and metastases become difficult to see on ultrasound and CT scans. The study authors hypothesize that the porto-scanner guidance technique with Angio-CT for thermoablation treatment of CRC liver metastases will allow a better exploration of these metastases by allowing a better identification of the margins and thus ensure a more accurate and complete treatment for patients.
