Impact of Nutritional Indices on the Survival Outcomes of Patients with Colorectal Cancer.

ABSTRACT: Background:The effect of preoperative nutritional status on the survival of patients with colorectal cancer is still unknown. The purpose of our study was to examine the impact of the prognostic nutritional index (PNI), prealbumin (PAB) and the albumin to globulin ratio (AGR) on survival outcomes in patients with colon and rectal cancer. Methods:Between January 2012 and December 2013, 361 patients with colorectal cancer who underwent curative surgery in the survey and various clinical and haematological parameters were recorded. The optimal cut-off values of the PNI, PAB and AGR were determined by MedCalc software, and Cox regression analysis was performed to investigate the effect of the PNI, PAB and AGR on the overall survival (OS) of patients with colon and rectal cancer. Results:In patients with colon and rectal cancer, a high PNI, PAB, and AGR correlate with higher survival times. Receiver operating characteristic (ROC) curve analysis showed that at most time points, the PNI has a higher area under the curve (AUC) in predicting colon and rectal cancer OS. Multivariate Cox regression analysis showed that of the PNI, PAB and AGR, only the PNI was an independent risk factor for OS in patients with colon and rectal cancer. Patients with a high PNI were predicted to have higher OS (hazard ratio [HR]: 0.479; 95% confidence interval [CI]: 0.233-0.985; P = 0.045) in colon cancer and higher OS (HR: 0.225; 95% CI: 0.111-0.454; P < 0.001) in rectal cancer compared with patients with a low PNI. Conclusion:Preoperative PNI, PAB and AGR may be predictors of OS in patients with colon and rectal cancer after radical surgery, especially the PNI, which has a good ability to predict OS in both tumours.

Project description:BackgroundInflammation promotes the development of malignancy, while a variety of systemic markers of inflammation predict for worse cancer outcomes including recurrence and survival. Here, we evaluate the prognostic impact of cytokine concentrations, full blood count (FBC) differential ratios, cognitive function and fatigue on survival in patients with localised colorectal cancer (CRC).Patients and methodsData are from a prospective longitudinal study comparing cognitive function and fatigue in patients with CRC who did (n=173) and did not (n=116) receive adjuvant/neoadjuvant chemotherapy. Baseline blood results (prior to any chemotherapy) included cytokines and FBC from which neutrophil lymphocyte ratio, lymphocyte monocyte ratio, platelet lymphocyte ratio and platelet monocyte ratio were derived. Fatigue was measured with the Functional Assessment of Cancer Therapy-Fatigue subscale and cognitive function by a neuropsychological test battery. Kaplan-Meier methods were used to estimate disease-free survival (DFS) and overall survival (OS). Univariable and multivariable Cox regression analyses were performed to evaluate factors potentially prognostic of outcomes.ResultsAt a median follow-up of 91.2 months, 227 subjects (79%) are still alive, and 212 (73%) have no evidence of a recurrence. Five-year OS and DFS are 86% (95% CI 81% to 90%) and 77% (95% CI 71% to 82%), respectively. None of the cytokines (interleukin (IL-6), IL-1 and tumour necrosis factor) or differential ratios of blood components, fatigue or cognitive function was statistically related to DFS or OS. Patient educational status (P=0.018), stage of disease (P=0.032), alanine transaminase (P=0.003), lactate dehydrogenase (P=0.008) and carcinoembryonic antigen (P=0.002) were significant as prognostic covariates of OS in univariable analyses, with similar results for DFS.ConclusionNone of the a priori selected markers of inflammation, fatigue or cognitive function was associated with OS or DFS in this cohort of patients.Trial registration numberNCT00188331, Post-results.

Project description:BackgroundSmall randomized trials of early postoperative oral nutritional supplementation (ONS) suggest various health benefits following colorectal surgery (CRS). However, real-world evidence of the impact of early ONS on clinical outcomes in CRS is lacking.MethodsUsing a nationwide administrative-financial database (Premier Healthcare Database), we examined the association between early ONS use and postoperative clinical outcomes in patients undergoing elective open or laparoscopic CRS between 2008 and 2014. Early ONS was defined as the presence of charges for ONS before postoperative day (POD) 3. The primary outcome was composite infectious complications. Key secondary efficacy (intensive care unit (ICU) admission and gastrointestinal complications) and falsification (blood transfusion and myocardial infarction) outcomes were also examined. Propensity score matching was used to assemble patient groups that were comparable at baseline, and differences in outcomes were examined.ResultsOverall, patients receiving early ONS were older with greater comorbidities and more likely to be Medicare beneficiaries with malnutrition. In a well-matched sample of early ONS recipients (n = 267) versus non-recipients (n = 534), infectious complications were significantly lower in early ONS recipients (6.7% vs. 11.8%, P < 0.03). Early ONS use was also associated with significantly reduced rates of pneumonia (P < 0.04), ICU admissions (P < 0.04), and gastrointestinal complications (P < 0.05). There were no significant differences in falsification outcomes.ConclusionsAlthough early postoperative ONS after CRS was more likely to be utilized in elderly patients with greater comorbidities, the use of early ONS was associated with reduced infectious complications, pneumonia, ICU admission, and gastrointestinal complications. This propensity score-matched study using real-world data suggests that clinical outcomes are improved with early ONS use, a simple and inexpensive intervention in CRS patients.
