ABSTRACT
Introducción El hepatocarcinoma (HCC) es uno de los tumores más frecuentes, y su tratamiento potencialmente curativo es la cirugía: resección quirúrgica parcial o trasplante hepático. Objetivos Determinar la morbimortalidad, la supervivencia y sus factores asociados en pacientes con HCC según tipo de tratamiento quirúrgico: trasplante hepático o resección quirúrgica parcial. Material y métodos Estudio observacional de seguimiento retrospectivo de HCC diagnosticados y tratados de junio de 1994 a diciembre de 2007. Se realiza un análisis descriptivo de las variables, análisis de supervivencia Kaplan-Meier y regresión de Cox. Resultados En los 150 pacientes trasplantados, la incidencia de recidiva tumoral es del 13,3%, con supervivencias a 1, 3 y 5 años del 89,3, el 73,1 y el 61,4% respectivamente; el análisis multivariable demuestra que sólo el grado de diferenciación histológica es factor de riesgo independiente. En los 33 pacientes con resección quirúrgica parcial, la incidencia de recidiva tumoral fue del 51,5%, con supervivencias a 1, 3 y 5 años del 90,9, el 60,2 y el 38,6%. Se evidencia una mortalidad significativamente mayor en pacientes con estadio tumoral y TNM superiores. Conclusiones La supervivencia en el seguimiento es mayor con trasplante hepático y la recidiva tumoral es más frecuente en pacientes con resección quirúrgica parcial. Los resultados de supervivencia en pacientes trasplantados coinciden con el Registro Español y Europeo de Trasplante Hepático y el registro de la United Network for Organ Sharing (AU)
Introduction: Liver cancer (LC) is one of the most frequent tumours, in which the potentiallycurative treatment is surgery: partial surgical resection or liver transplant. Objectives: To determine the morbidity and mortality, survival, and their associated factors in patients with LC, according to the type of surgical treatment: partial surgical resection orliver transplant. Material and methods: A retrospective, observational follow-up study of LC patients diagnosedand treated from June 1994 to December 2007. A descriptive analysis of the variableswas performed, as well as a Kaplan- Meier survival analysis and Cox regression. Results: The incidence of tumour recurrence in the 150 transplant patients was 13.3%, with asurvival at 1, 3, and 5 years of 89.3%, 73.1% and 61.4%, respectively. The multivariate analysis showed that only the histological grade/differentiation was an independent risk factor. Inthe 33 patients with partial surgical resection, the incidence of tumour was 51.5%, with asurvival at 1, 3, and 5 years of 90.9%, 60.2%, and 38.6%, respectively. A significantly highermortality was observed in patients with higher tumour and TNM staging. Conclusions: The survival throughout follow-up was higher in liver transplant, and tumourrecurrence was more frequent in patients with partial surgical resection. The survivalresults in transplanted patients are consistent with the Spanish and European LiverTransplant Register and with the United Network for Organ Sharing register (AU)

Triple therapy combining an anticalcineurin agent, corticosteroids, and azathioprine (AZA) in liver transplantation has been frequently applied, particularly in Europe. Debates have arisen concerning the use of a third drug (AZA), mainly in patients receiving tacrolimus (TAC). An open-label, multicenter, prospective, and randomized trial was performed to assess the efficacy and safety of TAC and corticosteroids (dual therapy [D]) vs. TAC, corticosteroids, and AZA (triple therapy [T]) in liver transplantation. A total of 180 patients were randomized, 92 in D and 88 in T group. Patients were followed during 3 months for efficacy and safety and up to 24 months for patient and graft survival assessments. The rate of biopsy-proven acute rejection was higher in D than in T group (40.7% vs. 24.4%; P = 0.021). A higher incidence of positive HCV status in D group (55.6% vs. 40.7%; P = 0.049) may explain this difference, since significantly more patients of this HCV subpopulation experienced acute rejection when treated with D therapy (48% vs. 20%; P = 0.008). No treatment differences were apparent for HCV-negative patients. The 24-month graft survival tended to be inferior in T group, 69.8% vs. 75.8% (P = 0.283). Similar results were observed regarding patient survival at the same time point, with values of 72.9% vs. 76.9% (P = 0.573), favoring D group. Both regimens showed comparable safety profiles with the exception of hematological abnormalities, which were more frequently observed in T group. In conclusion, both regimens were shown to be effective although increased toxicity and a trend towards a lower graft and patient survival were observed in T group.
