Hepatic arterial infusion pump (HAIP) chemotherapy with floxuridine aims to control the liver disease and improve survival. The aim of this study was to assess the effectiveness of HAIP chemotherapy with floxuridine and concurrent systemic gem-cis in patients with unresectable liver-confined iCCA in the Netherlands.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>METHODS<\/jats:title>\n                    <jats:p>We performed a nonrandomized multicenter phase II trial. Treatment-na\u00efve patients and patients previously treated with systemic therapy were eligible. Up to six cycles of HAIP floxuridine and eight cycles of concurrent systemic gem-cis were administered. The primary endpoint was 1-year OS compared with a historical cohort.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS<\/jats:title>\n                    <jats:p>\n                      From January 2020 to September 2022, 50 patients had a pump placed. Two patients (4%) did not start HAIP floxuridine; one patient died due to COVID-19, and one patient had a hepatic arterial dissection. The remaining 48 patients (96%) started HAIP chemotherapy, combined with systemic gem-cis in the 37 patients (74%) who had not received gem-cis previously. Twenty-two patients (44%) achieved a partial response and 42 patients (84%) disease control at 6 months. Five patients (10%) converted to resection, of whom one had a complete pathologic response. The median OS was 22.3 months (95% CI, 19.7 to 35.9 months). The 1-year OS of 80.0% (95% CI, 69.6% to 91.9%) was superior to the historical control of 47% (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; .001).
