Serum Cytokines Correlate with Pretreatment Body Mass Index-adjusted Body Weight Loss Grading and Cancer Progression in Patients with Stage III Esophageal Squamous Cell Carcinoma Undergoing Neoadjuvant Chemoradiotherapy Followed by Surgery.

Serum Cytokines Correlate with Pretreatment Body Mass Index-Adjusted Body Weight Loss Grading and Cancer Progression in Patients with Stage III Esophageal Squamous Cell Carcinoma Undergoing Neoadjuvant Chemoradiotherapy Followed by Surgery. Circulating cytokines have been linked to the development of esophageal squamous cell carcinoma (ESCC) and its associated malnutrition process. Nonetheless, given the varied disease stages and treatment modalities in previous studies, the clinical relevance of their findings is limited. We retrospectively studied 52 patients with stage III ESCC who underwent neoadjuvant chemoradiotherapy and curative-intent surgery. We investigated the association of clinicopathological features, pretreatment laboratory data, and pretreatment inflammatory status, as indicated by the levels of albumin, C-reactive protein, and 10 circulating cytokines, namely tumor necrosis factor-alpha (TNF-α), interferon-gamma, interleukin-1-beta (IL-1ß), IL-4, IL-6, IL-8, IL-12, IL-13, IL-17A, and IL-23, with malnutrition, as shown by body mass index-adjusted body weight loss (BMI-BWL) grading, cancer progression. Half the patients showed severe malnutrition and high BMI-BWL grades (3 and 4). Multivariate analysis revealed an independent association between the levels of three cytokines (TNF-α, ≤ 5.8 pg/ml; IL-1ß, > 0.4 pg/ml; IL-6, ≤ 12.4 pg/ml) and high BMI-BWL grades and between IL-4 levels > 22.5 pg/ml and cancer progression. All 10 cytokines were closely correlated with each other. In conclusion, TNF-α, IL-1ß, and IL-6 were independent markers of malnutrition status and IL-4 was a prognostic factor for cancer progression in this patient population.

Body Mass Index-Adjusted Body Weight Loss Grading Predicts Overall Survival in Esophageal Squamous Cell Carcinoma Patients.

PURPOSE: Various malnutrition and inflammation criteria were associated with prognosis of esophageal squamous cell carcinoma (ESCC) patients. Nonetheless, the interplay of clinicopathological features, malnutrition, and inflammation criteria with overall survival in ESCC patients remains unclear. METHODS: We retrospectively reviewed medical records of 205 patients diagnosed with ESCC between 2007 and 2012, and evaluated the status of participant malnutrition and inflammation, including body mass index < 18.5 kg/m2, body weight loss > 5.0%, serum albumin level < 3.5 g/dl, neutrophil-to-lymphocyte ratio > 3.5, platelet-to-lymphocyte ratio > 20, prognostic nutrition index < 40, blood total lymphocyte count < 1600 cells/mm3, and grades of body mass index-adjusted body weight loss (combined BMI-BWL). We assessed the association of clinicopathological features, nutritional status, and inflammation condition with overall survival using univariate and multivariate Cox regression analyses. RESULTS: The mean overall survival of ESCC patients was 28.8 mo,. The multivariate logistic regression model after adjustment for clinicopathological variables, malnutrition status, inflammation condition, and co-morbid status found that tumor stage and grades of combined BMI-BML served as equally important prognostic factors for overall survival. CONCLUSIONS: Advanced tumor stage and high grades of combined BMI-BWL were independent prognostic factors for overall survival in ESCC patients.

Phenylalanine- and leucine-defined metabolic types identify high mortality risk in patients with severe infection.

OBJECTIVE: To investigate the prognostic value of phenylalanine and leucine in patients with severe infection. METHODS: Ninety-three patients with infection who had a quick Sequential Organ Failure Assessment (qSOFA) score ≥2 were enrolled. Plasma phenylalanine, leucine, albumin, C-reactive protein, pre-albumin, and transferrin were measured and the SOFA score at enrollment was calculated after hospitalization. RESULTS: During the 3-month follow-up, 30 (32.3%) patients died. Death was associated with higher SOFA scores, a higher incidence of bacteremia and admission to the intensive care unit, higher C-reactive protein and phenylalanine levels, worse kidney function, and lower pre-albumin and transferrin levels. Patients were categorized into three groups: high-risk type 1 (phenylalanine ≥84µM), high-risk type 2 (phenylalanine <84µM and leucine <93µM), and low-risk (other). Compared to the low-risk type patients, high-risk type 1 and 2 patients had higher mortality rates (hazard ratio 10.1 (95% CI 2.33-43.5) and hazard ratio 5.56 (95% CI 1.22-25.4), respectively). Type 1 patients had higher SOFA scores, a higher incidence of admission to the intensive care unit, and higher C-reactive protein and leucine levels. Type 2 patients had lower albumin and hemoglobin levels. Multivariable analysis showed that both high-risk types were independent predictors of death. CONCLUSIONS: Phenylalanine- and leucine-defined risk classifications provide metabolic information with prognostic value for patients with severe infection.

Prognostic Significance of Low Body Mass Index and Betel-Quid Use in the 5-Year Survival Rates of Esophageal Squamous Cell Carcinoma Patients.

AIM: This study aimed to examine the relationship between clinicopathological features, varied malnutrition criteria, and survival in esophageal squamous cell carcinoma (ESCC) patients. METHODS: Six malnutrition criteria (body mass index (BMI) < 18.5 kg/m2, serum albumin level < 3.5 g/dL, neutrophil-to-lymphocyte ratio (NLR) > 3.5, platelet-to-lymphocyte ratio (PLR) > 17, prognostic nutrition index (PNI) < 40, and blood total lymphocyte count (TLC) < 1,600 cells/mm3) were measured in 205 ESCC patients at the time of diagnosis. Malnutrition status and clinicopathological features were tested for prognostic effects on the 5-year survival rate. RESULTS: Malnutrition rates vary according to nutrition assessment tools, ranging from 21.5% based on BMI < 18.5 kg/m2 to 67.8% based on PNI < 40. These rates are associated with increased inflammation, but they showed no difference among various tumor stages. After adjustment of demographic variables and comorbid status, advanced tumor stage, low BMI at diagnosis, and betel quid use showed prognostic significance in the 5-year survival rate based on a multivariate logistic regression analysis. CONCLUSIONS: Different nutrition assessment criteria produced different malnutrition rates. Advanced tumor stage, low BMI at diagnosis, and betel quid use were independent prognostic factors for worse survival of ESCC patients.
