Radioembolização no Tratamento do Carcinoma Hepatocelular

Abstract

Introdução: O carcinoma hepatocelular constitui uma importante causa de mortalidade a nível global e corresponde à principal neoplasia primária malignado fígado. No momento do diagnóstico, a maior parte dos doentes não tem critérios para a realização de um tratamento com intuito curativo. Porém, atualmente, estão disponíveis diversas abordagens terapêuticas para esta neoplasia, nomeadamente a radioembolização transarterial. Apesar de ser uma técnica vastamente utilizada na prática clínica, este tipo de tratamento locorregional tem uma aplicabilidade limitada nas atuais diretrizes. Objetivos: Este trabalho tem como principal objetivo efetuar uma revisão sobre a aplicabilidade da radioembolização nos diferentes estadios do carcinoma hepatocelular e perceber a possibilidade da associação desta técnica a outras modalidades de tratamento, nomeadamente a resseção hepática e o transplante hepático.Materiais e Métodos: A pesquisa foi realizada nas bases de dados PubMed e Embase, entre setembro de 2023 e março de 2024, incluindo publicações uni ou multicêntricas relativamente ao tratamento com radioembolização no carcinoma hepatocelular, comparação com outras técnicas locorregionais e a sua associação com outras modalidades terapêuticas, assim como artigos em indivíduos com idade superior a 18 anos.Resultados: Dos 998 artigos identificados, após excluídos os duplicados e avaliação dos títulos e resumos, 98 artigos foram selecionados e acedidos para efeitos de elegibilidade. Isto permitiu identificar 54 artigos. Posteriormente foram identificados termos secundários pertinentes de forma a detetar bibliografia adicional, resultando num total de 58 publicações analisadas.Discussão: Foi avaliada a utilização da radioembolização em diferentes estadios e em doentes com patologias específicas, a sua eficácia em comparação com a quimioembolização, assim como a associação desta técnica com outros tipos de tratamentos. Também foram abordados preditores de sobrevivência e prognóstico deste procedimento e a toxicidade associada ao mesmo.Conclusão: A radioembolização é uma técnica segura e eficaz em vários estadios do carcinoma hepatocelular, necessitando de uma seleção cuidadosa dos doentes, e é um procedimento que permite servir de ponte e downstaging para a resseção cirúrgica e para o transplante hepático, em doentes que inicialmente não eram candidatos a estes tratamentos curativos. No futuro, há necessidade de mais investigação nesta área, de forma a aumentar a sua aplicabilidade nas recomendações de tratamento.

Introduction: Hepatocellular carcinoma is an important cause of mortality worldwide and is the main primary malignant neoplasm of the liver. At the time of diagnosis, most patients do not meet the criteria for curative treatment. However, various therapeutic approaches are currently available for this neoplasm, including transarterial radioembolization. Despite being a technique widely used in clinical practice, this type of locoregional treatment has limited applicability in current guidelines. Objectives: The main objective of this work is to review the applicability of radioembolization in the different stages of hepatocellular carcinoma and to understand the possibility of associating this technique with other treatment modalities, namely liver resection and liver transplantation.Materials and Methods: Research was conducted within the PubMed and Embase databases between September 2023 and March 2024, including single or multicentre publications on radioembolization treatment in hepatocellular carcinoma, comparison with other locoregional techniques and its association with other therapeutic modalities, as well as articles on individuals over the age of 18.Results: Of the 998 articles identified, after excluding duplicates and evaluating titles and abstracts, 98 articles were selected and accessed for eligibility purposes. This enabled 54 articles to be identified. Subsequently, relevant secondary terms were identified in order to detect additional bibliography, resulting in a total of 58 publications analyzed.Discussion: The use of radioembolization at different stages and in patients with specific pathologies was evaluated, as was its efficacy in comparison with chemoembolization, and the association of this technique with other types of treatment. Predictors of survival and prognosis of this procedure and the toxicity associated with it were also discussed.Conclusion: Radioembolization is a safe and effective technique in various stages of hepatocellular carcinoma, requiring careful patient selection, and it is a procedure that allows bridging and downstaging to surgical resection and liver transplantation in patients who were not initially candidates for these curative treatments. In the future, there is a need for more research in this area in order to increase its applicability in treatment recommendations.
