Abstract

CAMPOS, Samara Bomfim Gomes et al. Interleukin-6 and triceps skinfold are associated with severity/cancer stage in newly-diagnosed colorectal cancer patients. Nutr. Hosp. [online]. 2021, vol.38, n.5, pp.1034-1039.  Epub Jan 24, 2022. ISSN 1699-5198.  https://dx.doi.org/10.20960/nh.03696.

Introduction:

colorectal cancer (CRC) has an important impact on morbidity and mortality globally, and nitroxidative stress, inflammation, and nutritional status are linked with its progression.

Aim:

to analyze the association of inflammatory, anthropometric, functional, and oxidative markers with tumor stage in newly-diagnosed CRC patients at a public reference center in Maceió, Alagoas, Brazil.

Methods:

patient-generated subjective global assessment was applied, and weight, height, arm circumference, triceps skinfold (TSF), arm muscle circumference, and handgrip strength were obtained. A fasting blood sample was collected, centrifuged, and the serum was stored at -80 °C until the analysis. Malonaldehyde levels were quantified by HPLC (high-performance liquid chromatography) and cytokines, namely tumor necrosis factor-alpha, and interleukins IL-6, IL-8, and IL-17 were analyzed by ELISA. Patients were grouped according to cancer stage into group 1 (stage 0-III) and group 2 (stage IV). A binary logistic regression analysis was performed, adjusted for sex and age, to assess the relationships between the variables studied and cancer stage. Significance was considered when p < 0.05.

Results:

twenty-eight CRC patients were included, twenty (71.4 %) from group 1 and eight (28.6 %) from group 2. The binary logistic regression revealed that lower TSF adequacy (OR = 0.929; CI 95 % = 0.870-0.993; p = 0.029) and higher IL-6 levels (OR = 1.001; CI 95 % = 1.000-1.002; p = 0.012) increased the chance of patients having tumor stage IV.

Conclusion:

These data support that IL-6 and TSF may help in cancer stage assessment in clinical practice. Modulation of inflammation by IL-6 levels may be a target in CRC treatment.
