Radioembolization (RE) is a promising treatment option for biliary tract cancers (BTC). We report here the largest series to date using this treatment modality.


We retrospectively studied data from 64 patients treated outside prospective clinical trial at our institution. We studied baseline characteristics as potential prognostic factors. We studied dose delivered to the tumor as predictive factors of outcomes in patients not receiving concomitant chemotherapy.


The Progression-Free Survival and Overall Survival (OS) were 7.6 months [95% Confidence Interval (CI): 4.6–10.6] and 16.4 months [95% CI: 7.8–25.0] in the whole cohort. The factors independently associated with OS in multivariable analysis were the primary localization of ICC (HR = 0.27, 95% CI: 0.11–0.68, p = 0.005) and a PS > 0 (HR = 2.21, 95% CI: 1.11–4.38, p = 0.024). During follow-up, 12 patients (19%) underwent surgery following downstaging, with a median OS of 51.9 months. In patients not treated with concomitant chemotherapy (n = 31), OS was significantly higher in patients with a dose delivered to the tumor 260Gy or higher than in patients with a dose delivered to the tumor lower than 260Gy (median 28.2 vs 11.4 months, log-rank p = 0.019).


Our results confirm that RE is a promising treatment modality in BTC. A high proportion of patients could be downstaged to surgery, with promising long-term survival. Dose delivered to the tumor correlated with clinical outcomes when chemotherapy was not used concomitantly.
