Resumen:
Simple Summary Radioembolization is a locoregional therapy used in primary liver malignancies with different applications depending on the treatment goal. The aim of this retrospective study was to evaluate postoperative and long-term survival outcomes of patients with unresectable or high biological risk HCC and ICC treated with RE that were finally rescued to liver surgery with curative intent. In a cohort of 34 patients, we assessed that liver resection and transplantation after RE seem safe and feasible with adequate short-term outcomes. Moreover, long-term outcomes after RE and LR were optimal, with a 10-year OS rate greater than 50% for HCC and ICC patients. On the other hand, the 10-year OS rates from RE were also greater than 50% for patients with HCC downstaged or bridged to LT. Radioembolization (RE) may help local control and achieve tumor reduction while hypertrophies healthy liver and provides a test of time. For liver transplant (LT) candidates, it may attain downstaging for initially non-candidates and bridging during the waitlist. Methods: Patients diagnosed with HCC and ICC treated by RE with further liver resection (LR) or LT between 2005-2020 were included. All patients selected were discarded for the upfront surgical approach for not accomplishing oncological or surgical safety criteria after a multidisciplinary team assessment. Data for clinicopathological details, postoperative, and survival outcomes were retrospectively reviewed from a prospectively maintained database. Results: A total of 34 patients underwent surgery following RE (21 LR and 13 LT). Clavien-Dindo grade III-IV complications and mortality rates were 19.0% and 9.5% for LR and 7.7% and 0% for LT, respectively. After RE, for HCC and ICC patients in the LR group, 10-year OS rates were 57% and 60%, and 10-year DFS rates were 43.1% and 60%, respectively. For HCC patients in the LT group, 10-year OS and DFS rates from RE were 51.3% and 43.3%, respectively. Conclusion: Liver resection after RE is safe and feasible with optimal short-term outcomes. Patients diagnosed with unresectable or high biological risk HCC or ICC, treated with RE, and rescued by LR may achieve optimal global and DFS rates. On the other hand, bridging or downstaging strategies to LT with RE in HCC patients show adequate recurrence rates as well as long-term survival.
