CT-Guided Percutaneous Microwave Ablation of Sclerosing Hepatic Carcinoma.

CT-Guided Percutaneous Microwave Ablation of Sclerosing Hepatic Carcinoma. Can J Gastroenterol Hepatol. 2020;2020:8881978 Authors: Song H, Ding H, Zhu C Abstract Sclerosing hepatic carcinoma (SHC) is a rare subtype of hepatic carcinoma that can be caused by various pathogeneses. The histological characteristics of SHC demonstrate its high resistance to chemoembolization and thermal ablation; thus, surgical resection represents the primary option for the majority of patients. However, a small proportion of patients who cannot withstand surgery or who have inoperable tumors may not receive adequate treatment, causing the progression of cancer and related high mortality. To overcome the high puncture resistance, high thermal resistance, and poor thermal conductivity of microwave ablation, we developed percutaneous no-touch multiple-site microwave ablation (NTMSWA) to ablate SHC lesions. In this retrospective study, 96 and 41 patients underwent NTMSWA and surgery, respectively. In the NTMSWA group, tumor size and histological classification were determined by medical imaging and tissue biopsy before ablation, and then a personalized ablation regimen was performed. Complete ablation was achieved in a single session in 81 out of 96 (84.4%) patients. The median survival (MS) of the 90 patients who underwent NTMSWA was 51 months, and the overall survival (OS) rate at 5 years was 49.1%. In contrast, the MS in the control group was 57 months, ...
