Abstract

Among biliary tract cancers, intrahepatic cholangiocarcinoma (ICC) has different characteristics compared with those in other sites. Current guidelines suggest several treatment options for ICC, including stereotactic body radiation therapy (SBRT). However, the role of SBRT in locally advanced ICC is unclear. The aim of the present study was to present a systematic review on the efficacy and safety of SBRT in ICC. A systematic review based on the PRISMA methodology was performed. Only papers reporting outcomes in terms of overall survival (OS) after SBRT in inoperable patients with ICC were included. Secondary aims were local control (LC), progression‑free survival (PFS) and treatment‑related toxicity. Six papers (145 patients) were included in the present analysis. SBRT was frequently used as a salvage treatment, since 28.6‑66.7% of patients received previous systemic or local treatments. The median SBRT dose was 45 Gy delivered in 3‑5 fractions. The median follow‑up was 16 months, and median OS time was 14 months (range, 10‑48 months). In one of the included studies, SBRT was significantly superior in terms of OS compared with both chemoradiation and trans‑arterial‑radio‑embolization. The 1‑year LC rate was 85% in one study, and 1‑year PFS rates were 50 and 68% in two studies, respectively. Toxicity was generally not reported in detail or was reported including other sites of biliary cancers. Overall, limited evidence was available on the efficacy of SBRT in ICC, which should be further investigated in prospective studies with a larger number of patients. However, based on the available data, SBRT seems to produce similar results compared with other ICC treatments, with the advantage of being a very short and non‑invasive therapy. Therefore, SBRT should be considered in selected patients with ICC.
