CCA arises from the epithelial cells lining the bile ducts and can be classified as intrahepatic, perihilar, or distal based on the site of origin in the biliary tree. Surgical resection is the definitive curative therapy for early-stage intrahepatic CCA; however, only a minority of patients may be ideal surgical candidates. Percutaneous microwave ablation (MWA) is a minimally invasive procedure widely used for hepatocellular carcinoma and colorectal cancer metastases to the liver. Growing evidence suggests MWA can play a role in the management of patients with early-stage intrahepatic CCA. In this study, we aim to describe the safety and efficacy of MWA for the management of intrahepatic CCA.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st2\">\n<jats:title>Material and Methods:<\/jats:title>\n<jats:p>A retrospective review of patients with intrahepatic CCA treated with MWA at our tertiary referral medical center was performed. Eight patients were treated between 2014 and 2019. Diagnosis of CCA was made based on histopathological studies of samples obtained by surgical resection or percutaneous liver biopsy. All procedures were performed under computed tomography (CT) guidance using a high-power single antenna MWA system. General anesthesia was used for all procedures. Patient medical history, procedural technical information, outcomes, and follow-up data were reviewed. Progression-free survival was estimated with a Kaplan\u2013Meier curve.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st3\">\n<jats:title>Results:<\/jats:title>\n<jats:p>A total of 25 tumors with an average size of 2.2 \u00b1 1.7 cm (range 0.5\u20137.8) were treated with MWA. Our cohort consisted of eight patients (4 males and 4 females) with an average age of 69.3 \u00b1 5.7 years (range 61\u201379). Three out of eight (3\/8, 37.5%) patients were treated initially with surgical resection. NASH-related cirrhosis was documented in 3\/8 (37.5%) patients, while 1\/8 (12.5%) had alcoholic cirrhosis; the remaining 4 patients (4\/8, 50%) did not have cirrhosis. All patients were discharged within 24 h after ablation. Average total follow-up time was 10.6 \u00b1 11.8 months (range 0\u201341). The incomplete ablation rate and local recurrence rate were 4% (1\/25 lesions) and 12% (3\/25 lesions), respectively.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st4\">\n<jats:title>Conclusion:<\/jats:title>\n<jats:p>In patients who do not qualify for surgical resection, MWA is a safe alternative therapy for the treatment of intrahepatic CCA.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/jcis_59_2023","type":"journal-article","created":{"date-parts":[[2024,2,13]],"date-time":"2024-02-13T08:53:28Z","timestamp":1707814408000},"page":"4","update-policy":"http:\/\/dx.doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Percutaneous
