The clinicopathological characteristics relevant to prognosis after surgical treatment of intrahepatic cholangiocarcinoma (ICC) remain unclear. In this study, the clinicopathological features of 19 patients with mass-forming ICC, the most common form of the disease, were reviewed to analyze prognostic determinants. Two or more segmentectomies of the liver with systematic lymphadenectomy were performed in 18 patients. Resection of the extrahepatic bile duct was performed in 14 patients, and reconstruction of the portal vein was accomplished in 5 patients. Stage IVA or IVB tumors were seen in 13 patients, and lymph node (LN) metastasis was present in 14 patients. The estimated 5-year survival rate after surgery for mass-forming ICC was 28%, with median survival time of 18 months. In univariate analysis, five variables were determined to be significantly correlated with poor survival of patients with mass-forming ICC after surgery. These variables include mass-forming ICC with periductal infiltration, perineural invasion, portal vein invasion, presence of intrahepatic metastasis, and two or more LN metastases. Survival rates of 5 patients without LN metastasis and 6 patients with a single LN metastasis were 80% and 33% at 5 years, respectively, while 8 patients with two or more LN metastasis failed to survive beyond 2 years. Multivariate analysis revealed the presence of intrahepatic metastasis to be an independent prognostic factor of poor survival. Hepatectomy with resection of the extrahepatic bile duct and systematic lymphadenectomy yields a good chance for prolonged survival for patients with mass-forming ICC when the lesion is singular and LN metastasis is limited to a regional LN. Because the presence of intrahepatic metastasis was closely related to a poor prognosis in patients with mass-forming ICC, efficacious chemotherapy would be needed to control development of the lesion.
RésuméLes caractéristiques clinicopathologiques influençant le pronostic après traitement des cholangiocarcinomes intra-hépatiq.ues (CIH) ne sont pas claires. Dans cette étude, les caractéristiques clinicopathologiques chez 19 patients porteurs de CIH à forme tumorale, la forme la plus fréquente, ont été analysés à des fins pronostiques. On a réalisé une segmentectomie de deux segments ou plus avec lymphadénectomie systématique chez 18 patients, une résection des voies biliaires extra-hépatiques chez 14 et une reconstruction de la veine porte chez 5 patients. Treize patients avaient une tumeur stade IVA ou IVB; 14 avaient des métastases ganglionnaires. La survie à 5 ans après chirurgie pour CIH à forme tumorale a été de 28%; la médiane de survie a été de 18 mois. En analyse univariée, on a trouvé cinq variables significativement associées à une survie médiocre chez les patients opérés de CIH à forme tumorale. Ces variables sont un CIH avec infiltration péricanulaire, un envahissement perineural, un envahissement portai, la présence de métastases hépatiques, et des métastases de deux ganglions ou plus. La survie de cinq patients sans métastase ganglionnaire et de six patients avec une seule métastase ganglionnaire ont été, respectivement, de 80% et de 33% à 5 ans, alors qu’aucun des huit patients avec deux métastases ganglionnaires ou plus n’a survécu au-delà de deux ans. En analyse multivariée, la présence de métastases intrahépatiques était un facteur indépendant de mauvais pronostic. Une hépatectomie avec résection des voies biliaires extra-hépatiques associée à un curage lymphatique systématique améliore les chances de survie prolongée en cas de CIH à forme tumorale lorsque la lésion est unique et les métastases ganglionnaires sont limitées à un seul ganglion lymphatique régional. Puisque la présence de métastases intrahépatiques est étroitement en rapport avec un mauvais pronostic chez les patients porteurs de CIH à forme tumorale, une chimiothérapie efficace est nécessaire pour contrôler l’évolution.
ResumenTras el tratamiento quirúrgico, las características clínicopatológicas pronósticas más importantes para los pacientes con colangiocarcinomas intrahepáticos (ICC) son poco conocidas. En este estudio se revisan las características clínicopatológicas más frecuentes en 19 pacientes con grandes tumores ICC, con objeto de determinar los factores pronósticos más importantes. 18 casos fueron tratados mediante dos o más segmentectomías hepáticas y linfadenectomía sistemática. En 14 pacientes se procedió a la resección y subsiguiente reconstrucción de la vía biliar extrahepática y en 5 de la vena porta. 13 pacientes pertenecían al estadio IV A o IV B y adenopatias metastásicas (LN) se registraron en 14 enfermos. Tras el acto quirúrgico el porcentaje medio estimado de supervivencia a los 5 años fue del 28%, con un tiempo de supervivencia de 18 meses. En pacientes con ICC que cursan con una tumoración macroscópicamente visible y palpable, el análisis univariante detectó 5 variables significativas por lo que a la escasa supervivencia se refiere: tumoración ICC con infiltración periductal, invasión perineural o de la vena porta, existencia de metástasis intrahepáticas y 2 o más adenopatías (LN) metastásicas. La supervivencia a los 5 años de 5 pacientes sin metástasis ganglionares (LN) y con una sola adenopatía metastásica fue del 80% y 33%, mientras que 8 pacientes con dos o más adenopatias metastásicas (LN) no sobrevivieron más de 2 años. El análisis multivariante demostró que las metástasis intrahepáticas constituyen un factor pronóstico independiente, de escasa supervivencia. La hepatectomía con resección de la vía biliar extrahepática asociada a una sistemática linfadenectomia puede, con suerte, prolongar la supervivencia de pacientes con tumores ICC palpables, cuando la tumoración es única y las adenopatias metastásicas son exclusivamente regionales. Dado que la presencia de metástasis intrahepáticas es signo de mal pronóstico, se precisa una eficaz quimioterapia para controlar el desarrollo de este tumor.
