ABSTRACT
ABSTRACT

Objective:

to evaluate the association between the nutritional and the inflammatory statuses of patients with cancer of the gastrointestinal tract undergoing surgical resection and to identify predictors of mortality in these patients.

Methods:

we conducted a prospective study of 41 patients with gastrointestinal tract cancer submitted to surgery between October 2012 and December 2014. We evaluated the nutritional status by subjective and objective methods. We assessed the inflammatory response and prognosis using the modified Glasgow Prognostic Score (mGPS), Neutrophil/Lymphocyte Ratio (NLR), Onodera Prognostic Nutritional Index (mPNI), Inflammatory-Nutritional Index (INI) and C-Reactive Protein/Albumin ratio (mPINI).

Results:

half of the patients were malnourished and 27% were at nutritional risk. There was a positive association between the percentage of weight loss (%WL) and the markers NLR (p=0.047), mPINI (p=0.014) and INI (p=0.015). Serum albumin levels (p=0.015), INI (p=0.026) and mPINI (p=0.026) were significantly associated with the PG-SGA categories. On multivariate analysis, albumin was the only inflammatory marker independently related to death (p=0.004).

Conclusion:

inflammatory markers were significantly associated with malnutrition, demonstrating that the higher the inflammatory response, the worse the PG-SGA (B and C) scores and the higher the %WL in these patients. However, further studies aimed at improving surgical outcomes and determining the role of these markers as predictors of mortality are required.

RESUMO

Objetivo:

avaliar a associação entre o estado nutricional e inflamatório em pacientes com câncer do trato gastrointestinal submetidos à ressecção cirúrgica e identificar variáveis preditoras de mortalidade nestes pacientes.

Métodos:

estudo prospectivo de 41 pacientes com câncer do trato gastrointestinal submetidos à cirurgia entre outubro de 2012 e dezembro de 2014. O estado nutricional foi avaliado por métodos subjetivos e objetivos. A resposta inflamatória e o prognóstico foram avaliados através do Escore Prognóstico de Glasgow modificado (mGPS), razão Neutrófilo/Linfócito (NLR), Índice Nutricional Prognóstico de Onodera (mPNI), Índice Inflamatório Nutricional (INI) e razão Proteína C-reativa/Albumina (mPINI).

Resultados:

metade dos pacientes estava desnutrida e 27% apresentavam-se em risco nutricional. Associação positiva foi encontrada entre percentual de perda de peso (%PP) e os marcadores NLR (p=0,047), mPINI (p=0,014) e INI (p=0,015) e os níveis séricos de albumina (p=0,015), INI (p=0,026) e mPINI (p=0,026) se associaram significativamente às categorias da ASG-PPP. Na análise multivariada, a albumina foi o único marcador inflamatório independentemente relacionado ao óbito (p=0,004).

Conclusão:

marcadores inflamatórios foram significativamente associados com a desnutrição, demonstrando que quanto maior a resposta inflamatória, piores foram os escores da ASG-PPP (B e C) e maior o %PP nesses pacientes. No entanto, mais estudos, com o objetivo de melhorar resultados cirúrgicos e determinar o papel desses marcadores como preditores de mortalidade são necessários.
