ABSTRACT
BACKGROUND: hepatocellular carcinoma (HCC) is a very frequent tumor. Screening for the disease is effective, but the prognostic factors are difficult to evaluate. OBJECTIVES: 1. To determine epidemiological data and the clinical course of HCC in our setting. 2. To compare patient survival according to whether screening is performed or not. 3. To evaluate survival prognostic factors. PATIENTS AND METHODS: data on the epidemiology and clinical course of patients diagnosed with HCC were collected on a prospective basis (January 2004-December 2006). Two groups were considered according to whether screening had been performed (group A) or not (group B). RESULTS: a total of 110 patients were diagnosed with HCC (70% males). The most common etiology of cirrhosis was hepatitis C (56.1%), and 69% presented mild liver failure (Child-Pugh grade A). The median follow-up was 1.8 years. Fifty-one percent had been subjected to screening. The diagnosis of HCC was established by imaging techniques in 48.2% of the cases, and by histological criteria in 51.8%. The median tumor size was 23 mm in group A and 28 mm in group B (p = 0.005). Treatment with curative intent was provided in 72% of the cases in group A and in 48% in group B (p = 0.011). The median overall survival was 1.99 years -2.67 years in group A and 1.75 years in group B (p = 0.05). The multivariate analysis of overall survival showed the type of treatment (OR = 2.82 95%CI: 1.3-6.12, p = 0.009) and liver function (OR = 1.71 95%CI: 1.1-2.68, p = 0.020) to be independent predictors of survival. CONCLUSIONS: screening allows the diagnosis of smaller lesions and a higher percentage of curative treatments. The degree of liver function and the provision of curative treatment are independent predictors of survival.

Introducción: el carcinoma hepatocelular (CHC) es un tumor muy prevalente. Su cribado es eficaz, pero los factores pronósticos son difíciles de evaluar. Objetivos: 1. Conocer datos epidemiológicos y evolución clínica en nuestra área. 2. Comparar la supervivencia de los pacientes según si seguían cribado o no. 3. Evaluar los factores pronósticos de supervivencia. Pacientes y métodos: se recogieron prospectivamente (enero 2004-diciembre 2006) datos epidemiológicos y evolución clínica de pacientes diagnosticados de CHC. Se estudiaron dos grupos en función del cribado (grupo A = cribado, grupo B = sin cribado). Resultados: 110 pacientes fueron diagnosticados de CHC (70% hombres). La etiología más frecuente de la cirrosis fue por virus C en 56,1%, eran Child A el 69%. El seguimiento mediano fue de 1,8 años. El 51% estaban en programa de cribado. El diagnóstico de CHC fue mediante pruebas de imagen en el 48,2% y 51,8% por criterios histológicos. El tamaño tumoral mediano fue 23 mm en el grupo A y de 28 mm en el B (p = 0,005). El tratamiento con intención curativa fue del 72% en el A y del 48% en el B (p = 0,011). La supervivencia global mediana fue de 1,99 años: grupo A. 2,67 años y grupo B 1,75 años (p = 0,05). El análisis multivariado de la supervivencia global evidenció que el tipo de tratamiento -OR = 2,82 (IC 95%: 1,3-6,12) (p = 0,009)- y la funcionalidad hepática -OR = 1,71 (IC 95%: 1,1-2,68) (p= 0,020)- predicen independientemente la supervivencia. Conclusiones: el cribado permite el diagnóstico de lesiones de menor tamaño y mayor porcentaje de tratamientos curativos. De forma independiente el grado de función hepática y la realización de un tratamiento curativo predicen la supervivencia(AU)
