ABSTRACT
ABSTRACT

Background:

The identification of prognostic factors of esophageal cancer has allowed to predict the evolution of patients.

Aim:

Assess different prognostic factors of long-term survival of esophageal cancer and evaluate a new prognostic factor of long-term survival called lymphoparietal index (N+/T).

Method:

Prospective study of the Universidad de Chile Clinical Hospital, between January 2004 and December 2013. Included all esophageal cancer surgeries with curative intent and cervical anastomosis. Exclusion criteria included stage 4 cancers, R1 resections, palliative procedures and emergency surgeries.

Results:

Fifty-eight patients were included, 62.1% were men, the average age was 63.3 years. A total of 48.3% were squamous, 88% were advanced cancers, the average lymph node harvest was 17.1. Post-operative surgical morbidity was 75%, with a 17.2% of reoperations and 3.4% of mortality. The average overall survival was 41.3 months, the 3-year survival was 31%. Multivariate analysis of the prognostic factors showed that significant variables were anterior mediastinal ascent (p=0.01, OR 6.7 [1.43-31.6]), anastomotic fistula (p=0.03, OR 0.21 [0.05-0.87]), N classification (p=0.02, OR 3.8 [1.16-12.73]), TNM stage (p=0.04, OR 2.8 [1.01-9.26]), and lymphoparietal index (p=0.04, RR 3.9 [1.01-15.17]. The ROC curves of lymphoparietal index, N classification and TNM stage have areas under the curve of 0.71, 0.63 and 0.64 respectively, with significant statistical difference (p=0.01).

Conclusion:

The independent prognostic factors of long-term survival in esophageal cancer are anterior mediastinal ascent, anastomotic fistula, N classification, TNM stage and lymphoparietal index. In esophageal cancer the new lymphoparietal index is stronger than TNM stage in long-term survival prognosis.
RESUMO
RESUMO Racional A identificação de fatores prognósticos do câncer de esôfago permitiu prever a evolução dos pacientes.

Objetivo:

Avaliar diferentes fatores prognósticos da sobrevida em longo prazo do câncer de esôfago e avaliar um novo fator prognóstico da sobrevida em longo prazo chamado índice linfoparietal (N+/T).

Método:

Estudo prospectivo do Hospital Clínico da Universidade do Chile, entre janeiro de 2004 e dezembro de 2013. Incluiu todas as operações de câncer de esôfago com intenção curativa e anastomose cervical. Os critérios de exclusão incluíram câncer em estágio 4, ressecções R1, procedimentos paliativos e operações de emergência.

Resultados:

Cinquenta e oito pacientes foram incluídos, 62,1% eram homens, a idade média foi de 63,3 anos. Um total de 48,3% eram escamosos, 88% eram cânceres avançados, a colheita média de linfonodos foi de 17,1. A morbidade cirúrgica pós-operatória foi de 75%, com 17,2% de reoperações e 3,4% de mortalidade. A sobrevida global média foi de 41,3 meses, a sobrevida em três anos foi de 31%. A análise multivariada dos fatores prognósticos mostrou que variáveis significativas foram elevação pelo mediastinal anterior (p=0,01, OR 6,7 [1,43-31,6]), fístula anastomótica (p=0,03, OR 0,21 [0,05-0,87]), classificação N (p=0,02, OR 3,8 [1,16-12,73]), estágio TNM (p=0,04, OR 2,8 [1,01-9,26]) e índice linfoparietal (p=0,04, RR 3,9 [1,01-15,17]. As curvas ROC do índice linfoparietal, classificação N e estádio TNM apresentam áreas abaixo da curva de 0,71, 0,63 e 0,64, respectivamente, com diferença estatística significativa (p=0,01).

Conclusão:

Os fatores prognósticos independentes de sobrevida em longo prazo no câncer de esôfago são a elevação mediastinal anterior, fístula anastomótica, classificação N, estágio TNM e índice linfoparietal. No câncer de esôfago, o novo índice linfoparietal é mais forte que o estágio TNM no prognóstico de sobrevida em longo prazo.
