Surgery and radioembolization of liver tumors

Surgical resection is considered the curative treatment par excellence for patients with primary or metastatic liver tumors. However, less than 40% of them are candidates for surgery, either due to non-modifiablefactors (comorbidities, age, liver dysfunction...), or to the invasion or proximity of the tumor to the mainvascular requirements, the lack of a future liver remnant (FLR) adequate to maintain postoperative liverfunction, or criteria of tumor size and number. In these last factors, hepatic radioembolization has beenshown to play a role as a presurgical tool, either by hypertrophy of the FLR or by reducing tumor size that manages to reduce tumor staging (term known as '' downstaging ''). To these is added a third factor, whichis its ability to apply the test of time, which makes it possible to identify those patients who presentprogression of the disease in a short period of time (both locally and at distance), avoiding a unnecessarysurgery. This paper aims to review RE as a tool to facilitate liver surgery, both through the experience ofour center and the available scientific evidence. (c) 2023 The Authors.
