ABSTRACT
ABSTRACT

Background:

The identification of prognostic factors of gastric cancer (GC) has allowed to predict the evolution of patients.

Aim:

Assess the reliability of the lymphoparietal index in the prediction of long-term survival in GC treated with curative intent.

Method:

Prospective study of the Universidad de Chile Clinical Hospital, between May 2004 and May 2012. Included all gastric cancer surgeries with curative intent. Exclusion criteria were gastrectomies due to benign lesions, stage 4 cancers, R1 resections, palliative procedures, complete esophagogastrectomies and emergency surgeries.

Results:

A total of 284 patients were included; of the sample 65.4% were male,mean age of 64.5 years,75% were advanced cancers, 72.5% required a total gastrectomy, 30 lymph nodes harvest. Surgical morbidity and mortality were 17.2% and 1.7%. 5-year survival was 56.9%. The N+/T index could predict long-term survival in all de subgrups (p<0.0001), although had a reliable prediction in early GC (p=0.005), advanced GC (p<0.0001), signet ring cell GC (p<0.0001), proximal GC (p<0.0001) and distal GC (p<0.0001). The ROC curves N+/T index, LNR and T classification presented areas below the curve of 0.789, 0.786 and 0,790 respectively, without a significant statistical difference (p=0.96).

Conclusion:

The N+/T index is a reliable quotient in the prognostic evaluation of gastric adenocarcinoma patients who have been resected with curative intent.
RESUMO
RESUMO Racional A identificação de fatores prognósticos do câncer gástrico (GC) permitiu predizer a evolução dos pacientes.

Objetivo:

Avaliar a confiabilidade do índice linfoparietal na predição de sobrevida em longo prazo em pacientes tratados com intenção curativa.

Método:

Estudo prospectivo do Hospital das Clínicas da Universidade de Chile, entre maio de 2004 e maio de 2012. Todas as operações de câncer gástrico foram com intenção curativa. Os critérios de exclusão foram gastrectomia por lesões benignas, cânceres estágio 4, ressecções R1, procedimentos paliativos, esofagogastrectomias completas e operações de emergência.

Resultados:

Foi incluído um total de 284 pacientes; da amostra 65,4% eram homens, com média de idade de 64,5 anos, 75% eram cânceres avançados, 72,5% necessitaram de gastrectomia total e 30 coletas de linfonodos. A morbimortalidade cirúrgica foi de 17,2% e 1,7%. Sobrevida em cinco anos foi de 56,9%. O índice N +/T pôde predizer a sobrevida em longo prazo em todos os subgrupos (p<0,0001), embora tivesse previsão confiável em GC precoce (p=0,005), GC avançado (p<0,0001), célula GC de anel de sinete (p< 0,0001), GC proximal (p<0,0001) e GC distal (p<0,0001). As curvas ROC N +/T, LNR e T apresentaram áreas abaixo da curva de 0,789, 0,786 e 0,790, respectivamente, sem diferença estatística significativa (p=0,96 ).

Conclusão:

O índice N +/T é um quociente confiável no prognóstico na avaliação de pacientes com adenocarcinoma gástrico que foram ressecados com intenção curativa.
