Abstract | RACIONAL: O hepatocarcinoma é o tumor hepático maligno mais freqüente em humanos e sua forte associação com a cirrose torna a abordagem terapêutica ainda um desafio. O transplante hepático é o tratamento de escolha para os pacientes cirróticos com hepatocarcinoma irressecável em estágio precoce OBJETIVO: Avaliar a evolução pós-transplante de 15 pacientes cirróticos com diagnóstico pré-operatório de hepatocarcinoma precoce irressecável que preenchiam os Critérios de Milão e foram submetidos a transplante hepático entre setembro de 1991 e dezembro de 2003 no Hospital de Clínicas da Universidade Federal do Paraná, Curitiba, PR MÉTODOS: Foram analisados retrospectivamente os dados clínicos dos 15 receptores de transplante hepático tendo como parâmetros principais a sobrevida do paciente e a ocorrência de recidiva tumoral após o transplante RESULTADOS: A idade média dos pacientes foi 49,2 ± 14,3 anos, sendo a hepatite crônica C a causa implicada em 60% dos casos. Em 80% dos pacientes realizou-se terapia adjuvante pré-transplante (quimioembolização ou alcoolização). Na análise dos explantes hepáticos constatou-se que 5 dos 12 pacientes (38,5%) submetidos a terapia adjuvante apresentavam necrose completa do tumor, enquanto os demais apresentavam alguma extensão de tecido tumoral viável. Em apenas 4 dos 15 explantes (26,6%) constatou-se invasão microvascular. A mediana do seguimento pós-transplante foi de 33 meses (8_71 meses), tendo ocorrido apenas um óbito precoce, não relacionado à recidiva tumoral (sepse biliar). A sobrevida pós-transplante livre de recurrência em 1 e 3 anos no grupo foi de 93% CONCLUSÕES: O transplante hepático é uma excelente alternativa de tratamento em pacientes cirróticos com hepatocarcinoma irressecável em fase precoce, alcançando elevados índices de sobrevida livre de recurrência tumoral.
BACKGROUD: Hepatocellular carcinoma is the most frequent malignant hepatic tumor in humans, and its association with cirrhosis makes the therapeutic approach still a challenge. Liver transplantation is the treatment of choice for cirrhotic patients with unresectable early hepatocellular carcinoma AIM: To evaluate the post-transplant outcome of a cohort of 15 cirrhotic patients with preoperative diagnosis of unresectable early hepatocellular carcinoma according the Milan criteria who underwent liver transplantation between September 1991 and December 2003 METHODS: We retrospectively reviewed the clinical data from 15 liver transplant recipients and the explanted livers were assessed for the efficacy of preoperative therapy. Patient survival and tumor recurrence were evaluated as primary outcome measures RESULTS: The mean age of the patients was 49.2 ± 14.3 years and hepatitis C was the etiology of the underlying liver disease in 60%. Preoperative therapy, either chemoembolization or percutaneous ethanol injection, was performed in 12 (86%) patients. Complete necrosis of all tumoral lesions were observed in 5 of 12 patients (44,66%); all others had variable amounts of viable tumor in the explanted liver. Only 4 of the 15 (26.6%) explanted livers had microscopic vascular invasion. The median post-transplant follow-up was 33 months (range: 8-71months) and no tumor recurrence was detected during this period. The only death was an early event not related to the tumor. The recurrence-free survival rates at 1 and 3 years were 93% CONCLUSION: Liver transplantation has emerged as a good alternative for cirrhotic patients with early hepatocellular carcinoma not amenable to curative resection, offering excellent recurrence-free survival rates. |
