ABSTRACT
ABSTRACT

Background:

About 50% of the patients with colorectal adenocarcinoma will present with liver metastasis and 20% are synchronic. Liver resection is associated with improvement in survival in comparison to chemotherapy alone.

Aim:

To analyze the overall survival in patients submitted to liver resection of colorectal cancer metastasis and prognostic factors related to the primary and secondary tumors.

Methods:

A retrospective analysis of a prospectively maintained database regarding demographic, primary tumor and liver metastasis characteristics.

Results:

There were 84 liver resections due to colorectal cancer metastasis in the period. The 5-year disease-free and overall survivals were 27.5% and 48.8% respectively. The statistically significant factors for survival were tumor grade (p=0.050), lymphovascular invasion (p=0.021), synchronous metastasis (p=0.020), as well as number (p=0.004), bilobar distribution (p=0.019) and diameter of the liver metastasis over 50 mm (p=0.027). Remained as independent negative predictive factors lymphovascular invasion (HR=2.7; CI 95% 1.106-6.768; p=0.029), synchronous metastasis (HR=2.8; CI 95% 1.069-7.365; p=0.036) and four or more liver metastasis (HR=1.7; CI 95% 1.046-2.967; p=0.033).

Conclusion:

The resection of liver metastasis of colorectal adenocarcinoma leads to good survival rates. Lymphovascular invasion was the single prognostic factor related to the primary tumor. Synchronous disease and four or more metastasis were the most significant factors related to the secondary tumor.
RESUMO
RESUMO Racional Cerca de metade dos pacientes com adenocarcinoma colorretal apresentará metástases hepáticas. Apesar da superioridade do tratamento cirúrgico, os pacientes com elas compõem um grupo muito heterogêneo.

Objetivo:

Descrever o impacto de fatores relacionados ao tumor primário e ao secundário na sobrevida após ressecção de metástases hepáticas colorretais.

Métodos:

Análise retrospectiva de base de dados mantida prospectivamente de pacientes operados.

Resultados:

Foram realizadas 84 hepatectomias para ressecção de metástases hepáticas de adenocarcinoma colorretal em 73 pacientes no período. A sobrevida global e livre de doença em cinco anos foram de 48,8 e 27,5%, respectivamente. Os principais preditores de sobrevida foram grau de diferenciação (p=0,050) e invasão angiolinfática (p=0,021) do tumor primário, metástases sincrônicas (p=0,020), número (p=0,004), distribuição bilobar (p=0,019) e diâmetro máximo maior que 50 mm (p=0,027) dos nódulos hepáticos. Foram significativos a presença de invasão angiolinfática (HR=2,7; IC 95% 1,106-6,768; p=0,029), metástases sincrônicas (HR=2,8; IC 95% 1,069-7,365; p=0,036) e número de nódulos hepáticos igual ou superior a quatro (HR=1,7; IC 95% 1,046-2,967; p=0,033).

Conclusão:

A ressecção de metástases hepáticas de adenocarcinoma colorretal proporciona melhora da sobrevida e os principais fatores prognósticos foram a invasão angiolinfática no tumor primário, metástases sincrônicas e quatro ou mais nódulos hepáticos.
