The nutritional status of patients with gastrointestinal carcinoma is frequently affected, being aggravated by the carcinogenesis that promote activation of the inflammatory process and subsequent activation of the immune system, with production of cytokines and acute phase proteins, such as C-reactive protein, which results in hypermetabolism, accelerating weight loss and progresses to cachexia. This study aimed to analyze the nutritional status and biochemical-clinical markers in patients with gastrointestinal carcinoma, treated at Hospital Universitário João de Barros Barreto (HUJBB), in Belém-PA. Was conducted a descriptive, observational and cross-sectional study involving patients with gastrointestinal carcinoma treated at HUJBB from december 2013 to july 2014. Nutritional assessment was conducted by anthropometric parameters, which included body mass index (BMI), percentage weight loss (%PWL), arm circumference (AC), arm muscle circumference (AMC), arm muscle area corrected (CAMA), triceps skinfold thickness (TST) and muscle adductor pollicis (MAP), biochemical parameters, by classifying hemoglobin, total lymphocyte count (TLC), albumin, transferrin, index-inflammatory nutritional prognosis (IPIN ) and subjective parameters, using the subjective global assessment produced by the patient (ASG-PPP), besides the identification and classification of cachexia. 44 patients were evaluated, 63.3% were male with a mean age of 61.2 years (±13.3); 95.50% were natural of Pará, 45.50% living in the countryside, 50.00% had incomplete education in primary and 52.30% had no family income. 63.60% of the patients evaluated, had stomach cancer; of these, 50.00% were in clinical stage IV and 73.30% in surgical treatment, with an average hospital stay of 45.85 days (± 32.97). In nutritional assessment was obtained 20.50% eutrophy in adults and 42.30% for seniors through BMI, however, in isolated assessment of muscle and fat compartments, there was 59.10% of severe depletion by of CAMA, 54.50% by the TST, 75.00% with the presence of depletion in AC and 68.18% in AMC. Severe weight loss was observed in 61.36% of the patients and in the MAP was obtained higher prevalence of moderate depletion (30.20%). At biochemical parameters, there was severe reduction in hemoglobin to 61.40% of patients, slight depletion of CTL in 56.80%, 47.70% for albumin and 45.50% with moderate depletion in transferrin. In the assessment of IPIN, was obtained medium risk complication for 56.80% of the patients. In ASG-PPP, 63.60% of patients were classified into severe malnutrition and the presence of symptomatic cachexia, was 54.50%. With regard to the correlation analysis, it was found that there was a positive and significant correlation of BMI with AMC, AC, TST, CAMA, MAP and hemoglobin; AMC with AC, and CAMA; AC with TST, CAMA, MAP, and hemoglobin; TST, CAMA; CAMA with MAP. In the principal component analysis, it was found as the most sensitive methods to detect malnutrition the assessment of AC, CAMA, AMC, BMI, TST, MAP, IPIN and evaluation of cachexia. Thus, the results obtained in this study indicate the nutritional impairment in patients with gastrointestinal carcinoma by different parameters, thus demonstrating that malnutrition occurs globally, with loss of both adipose tissue, muscle tissue as well as changes biochemical level.
