ABSTRACT

Liver transplantation is the curative therapy of choice for patients with early-stage HCC. Locoregional therapies are often employed as a bridge to reduce the risk of waitlist dropout; however, their association with posttransplant outcomes is unclear. We conducted a systematic review using Ovid MEDLINE and EMBASE to identify studies published between database inception and August 2, 2023, which reported posttransplant recurrence-free survival and overall survival among patients transplanted for HCC within Milan criteria, stratified by receipt of bridging therapy. Pooled HRs were calculated for each outcome using the DerSimonian and Laird method for a random-effects model. We identified 38 studies, including 19,671 patients who received and 20,148 patients who did not receive bridging therapy. Bridging therapy was not associated with significant differences in recurrence-free survival (pooled HR: 0.91, 95% CI: 0.77-1.08; I2 =39%) or overall survival (pooled HR: 1.09, 95% CI: 0.95-1.24; I2 =47%). Results were relatively consistent across subgroups, including geographic location and study period. Studies were discordant regarding the differential strength of association by pretreatment tumor burden and pathologic response, but potential benefits of locoregional therapy were mitigated in those who received 3 or more treatments. Adverse events were reported in a minority of studies, but when reported occurred in 6%-15% of the patients. Few studies reported loss to follow-up and most had a risk of residual confounding. Bridging therapy is not associated with improvements in posttransplant recurrence-free or overall survival among patients with HCC within Milan criteria. The risk-benefit ratio of bridging therapy likely differs based on the risk of waitlist dropout.

ABSTRACT

Se presentaron 29 pacientes con tumores primitivos o secundarios de hígado que fueron tratados por quimioembolización. El 76 por ciento presentaba evidente progresión oncológica previa al tratamiento. La quimioembolización consistió en la infusión intratumoral de una droga antiblástica asociada con un vector de fijación tumoral, complementada con una embolización. En los pacientes tratados con un objetivo oncológico se obtuvieron respuestas favorables en el 67 por ciento de los casos, mientras que en los tratados con un objetivo sintomático se obtuvieron respuestas favorables en 93 por ciento de los casos. Los mejores resultados se obtuvieron en los hepatocarcinomas y en las metástasis de tumores endocrinos. En 2 pacientes con una hepatectomia postquimioembolización, la anatomía patológica demostró necrosis total del tejido tumoral. La experiencia de esta corta serie coincide con la literatura en que la quimioembolización hepática es una alternativa terapeútica eficaz para los tumores hepáticos irresecables
