Abstract
PURPOSE Immunonutritional status is a known prognostic correlate in the context of gastric cancer (GC). In the present study, we investigated the prognostic relevance of a lipid profile-based immunonutritional score in patients with GC. METHODS Data pertaining to 224 patients with stage II and III GC who underwent curative gastrectomy were retrospectively analyzed. The total cholesterol-lymphocyte score (TL score) was defined as follows: patients with both low total cholesterol (TC) and total lymphocyte count were allocated a score of 2; patients with only one or none of these biochemical abnormalities were allocated a score of 1 or 0, respectively. RESULTS Among the serum lipid indices, low TC was the strongest predictor of cancer-specific survival (CSS; p = 0.001). On multivariate analysis, both low prognostic nutritional index (PNI) (p < 0.001) and high TL score (p = 0.003) were independent prognostic factors. PNI was significantly associated with peritoneal recurrence (p = 0.047), while TL score was significantly associated with locoregional and distant metastasis (p = 0.004 and p = 0.003, respectively). CONCLUSIONS TL score may facilitate risk stratification of patients based on CSS. TL score plus PNI may help predict the recurrence pattern in patients with stage II and III GC.

Abstract
BACKGROUND This study aimed to evaluate the predictive value of the preoperative Controlling Nutritional Status (CONUT) score, which comprehensively reflects protein and lipid metabolism as well as the immunocompetence among patients with stage 2 or 3 gastric cancer. METHODS From a retrospective database of 3484 patients who underwent gastrectomy for gastric cancer at nine Japanese institutions between 2010 and 2014, data for 626 patients with stage 2 or 3 cancer were retrieved. The study evaluated the significance of the associations between the optimal CONUT score cutoff values with the prognosis and the incidence of postoperative complications. RESULTS The study determined that 2 was the optimal CONUT score cutoff value for predicting mortality 2 years after surgery. The patients with a CONUT score of 2 or higher (CONUT-high group) were significantly older and had a worse Eastern Cooperative Oncology Group performance status, lower body mass index, and more advanced tumor-node-metastasis stage than the patients with a CONUT score lower than 2 (CONUT-low group). Overall, the survival time was significantly shorter in the CONUT-high group than in the CONUT-low group [hazard ratio (HR) 1.97; P < 0.0001]. A multivariable analysis showed that the CONUT score was an independent prognostic factor of overall survival. The CONUT score more significantly reflected the overall survival for patients who underwent postoperative adjuvant chemotherapy than for those who underwent surgery alone. Additionally, a high preoperative CONUT score was significantly associated with an increased incidence of postoperative pneumonia and prolonged hospitalization. CONCLUSIONS The study results suggest that the preoperative CONUT score may be a useful predictor of postoperative short- and long-term outcomes for patients with stage 2 or 3 gastric cancer.

Abstract
OBJECTIVE To analyze the impact of infectious complications and microbiology in the postoperative period after major oncologic neck surgeries. METHODS A retrospective study conducted in an oncology center, including all the consecutive patients who developed infectious complications after major neck cancer surgery, from October 2012 to May 2016 (44 months). Among other data, we collected TNM stage, ASA score, body mass index, comorbidities and habits, pre and postoperative hemoglobin levels, albumin serum levels, pre-surgical treatments, length of inpatient stay, isolated microbiological agents and the recorded complications and mortality rate. RESULTS In the studied period, 761 major neck surgeries were performed. Of these, 96 patients had complications (12.6%). Pharyngocutaneous fistula (PCF) was the most frequent complication (56%) and nosocomial pneumonia was the most common systemic complication (23%). Pseudomonas aeruginosa was the principal microorganism of the 26 species isolated (15%). 12 deaths were registered. Using multiple linear regression we concluded that flap/cutaneous necrosis and PCF were complications with statistical significance that prolonged inpatient stay. The same complications had significant relative risk for more than 30 days of hospitalization. CONCLUSION The postoperative period is critical for the successful treatment of head and neck oncology patients. PCF and flap/cutaneous necrosis were the principal complications which worsened the outcomes during this critical period. The early recognition and treatment of these complications is crucial.

Abstract
Background: C-reactive protein (CRP) is gaining credibility as a prognostic factor in different cancers. Cox's proportional hazard (PH) model is usually used to assess prognostic factors. However, this model imposes a priori assumptions, which are rarely tested, that (1) the hazard ratio associated with each prognostic factor remains constant across the follow-up (PH assumption) and (2) the relationship between a continuous predictor and the logarithm of the mortality hazard is linear (linearity assumption). Methods: We tested these two assumptions of the Cox's PH model for CRP, using a flexible statistical model, while adjusting for other known prognostic factors, in a cohort of 269 patients newly diagnosed with non-small cell lung cancer (NSCLC). Results: In the Cox's PH model, high CRP increased the risk of death (HR=1.11 per each doubling of CRP value, 95% CI: 1.03–1.20, P=0.008). However, both the PH assumption (P=0.033) and the linearity assumption (P=0.015) were rejected for CRP, measured at the initiation of chemotherapy, which kept its prognostic value for approximately 18 months. Conclusion: Our analysis shows that flexible modeling provides new insights regarding the value of CRP as a prognostic factor in NSCLC and that Cox's PH model underestimates early risks associated with high CRP.

Abstract
Patients undergoing radical radiotherapy for head and neck cancers often experience significant complications. We sought to evaluate the impact of prophylactic gastrostomy tubes (PGTs) among these patients on four easily evaluable adverse outcomes, namely, absolute weight loss, percentage weight loss, admissions for nutritional reasons and treatment interruptions. A retrospective review was carried out on patients undergoing radical radiotherapy for primary head and neck cancers from September 1999 to October 2005 at the Wellington Blood and Cancer Centre (n = 71). PGTs were placed in 7 (10%) patients. Patients with PGTs were compared with the patients without PGTs (the control group) by univariate and multivariate analyses. By univariate analysis, there was no significant difference in absolute or percentage weight loss between those with PGTs and the control group. By multivariate analysis, those with PGTs lost 5.2% (P = 0.016) less weight than the control group. There were no significant differences between the two groups with regard to admissions for nutritional reasons or treatment interruptions. The use of PGTs can reduce weight loss in patients undergoing radical radiotherapy for head and neck cancers, and its use should be further evaluated in future studies.

Abstract
PURPOSE Evidence suggests that the majority of colorectal carcinomas arise from adenomas, and L-arginine suppresses colorectal tumorigenesis. We suppose that L-arginine may inhibit the process of carcinogenesis from colorectal adenoma to adenocarcinoma. The aim of this study was to investigate the effects of L-arginine on the formation and development of colorectal tumors. EXPERIMENTAL DESIGN We selected 60 patients with colorectal cancer and 60 patients with colorectal adenoma (CRA) and divided them into four groups of 30 patients each. We gave 30 g (120 mL) of L-arginine everyday for 3 days to the test groups, whereas L-arginine was substituted by 5% glucose in the control groups. The expression of the proliferating cell nuclear antigen, survivin, and nitric oxide synthase was examined immunohistochemically, and ornithine decarboxylase (ODC) activity was examined spectrophotometrically. Serum nitric oxide (NO) was detected by the Griess assay. RESULTS In patients with CRA, the proliferating cell nuclear antigen and survivin labeling indexes and ODC activity of the tumor and paratumor mucosa in the L-arginine-treated group after L-arginine treatment were significantly lower as compared with the corresponding pretreatment values (P < 0.01). Moreover, inducible nitric oxide synthase expression in the tumor markedly increased after L-arginine treatment (P < 0.05). Serum NO levels in the patients with colorectal cancer were markedly higher than those in the patients with CRA, and L-arginine treatment was responsible for this increase (P < 0.05). CONCLUSIONS Our results show that L-arginine can restrain crypt cell hyperproliferation and the expression of survivin, an inhibitor of apoptosis protein. This suggests that L-arginine can block the formation and development of colorectal tumors, and this effect might be related to the increased serum NO concentration and decreased ODC activity.

Abstract
BACKGROUND The treatment of gastroduodenal outflow obstruction (GOO) caused by malignant diseases represents a significant challenge. Open surgical gastrojejunostomy (GJ) has been the treatment of choice, but it has high morbidity and mortality rates. More recently, endoscopic placement of self-expanding metallic stents (SEMS) has been proposed and the results of small, preliminary studies are encouraging. This study compared technical and clinical success, morbidity, mortality, and hospital stay in patients undergoing endoscopic and surgical treatment of GOO. METHODS Medical records of 60 consecutive patients with GOO seen between April 1997 and November 2002 were retrospectively reviewed. Because of extremely short life expectancy, 13 patients were treated by insertion of a double-lumen nasogastric-jejunal tube. The remaining 47 patients (28 men, 19 women; mean age 73.5 years, range 48-92 years) with unresectable pancreatic (33), gastric (7), metastatic lymph nodal (4), papillary (2), and biliary (1) tumors were treated by placement of a SEMS (24) or open surgical GJ (23). RESULTS The technical success rates were similar, but clinical success was lower in the GJ group (92% vs. 56%, p = 0.0067). The SEMS group had a shorter length of hospital stay (3.0 [1.4] days vs. 24.1 [10.3], p < 0.001). Thirty-day mortality was 30% in the GJ group, and 0% in the SEMS group ( p = 0.004). Morbidity was higher in the GJ compared with the SEMS group (61% vs. 17%, p = 0.0021). Mean survival was longer in the SEMS group (96.1 [9.6] days vs. 70.2 [36.2] days, p = 0.0165 for a single test of hypothesis; Bonferroni correction for a multiple testing removes this significance), consequently, out-of-hospital survival was longer for the SEMS group (93.2 [9.3] days vs. 46.0 [31.5] days, p < 0.001). None of the endoscopic procedures required the assistance of an anesthesiologist or the use of an operating room. CONCLUSIONS The results of this retrospective study suggest that SEMS insertion is better than surgical GJ for palliation of patients with GOO in terms of clinical success, morbidity, and mortality. Technical success rates were similar. SEMS placement should be proposed as the first-line treatment for relief of GOO. However, a randomized, comparative, prospective study of SEMS vs. laparoscopic GJ is needed.

Abstract
There are few reports on factors that determine survival in advanced gastrointestinal cancer with weight loss. In these patients (n = 91, median weight loss 16.6%), we prospectively examined the importance of metastatic spread, anthropometry, blood parameters, Karnofsky performance status, appetite, and the acute-phase response as predictors of survival. Survival was calculated from date of assessment to the most recent clinic attendance (> or = 30 mo) or until death. On multivariate analysis, metastatic spread (p < 0.05), Karnofsky performance status (p < 0.01), and C-reactive protein concentration (p < 0.001) had independent prognostic value. In locally advanced disease (n = 64), Karnofsky performance status and C-reactive protein concentration remained significant. There was a significantly lower survival in patients with an acute-phase response (median 136 days) than in patients with no response (median 466 days; p < 0.01). Performance status and the acute-phase response are associated, independent of weight loss, with survival duration in advanced gastrointestinal cancer patients.

Abstract
OBJECTIVE To conduct a meta-analysis of 11 randomized controlled trials comparing enteral nutritional support supplemented with key nutrients versus standard enteral nutritional support to determine effects on morbidity and mortality rates and hospital stay. BACKGROUND DATA Recent studies have shown that malnutrition occurs in up to 30% of patients undergoing gastrointestinal surgery, resulting in an increased risk of postoperative complications and death. With the realization that key nutrients can modulate inflammatory, metabolic, and immune processes, enteral nutritional regimens (supplemented with large amounts of key nutrients) have been developed for clinical use. METHODS Eleven prospective, randomized controlled trials evaluating 1009 patients treated with combinations of key nutrients (Impact, Immun-Aid) were evaluated. Outcome measures examined were the incidences of pneumonia, infectious complications, and death, and length of hospital stay. Meta-analyses were undertaken to obtain the odds ratio and 95% confidence interval for incidences of infectious complications, pneumonia, and death, and the weighted mean difference and 95% confidence interval for length of hospital stay. RESULTS The provision of nutritional support supplemented with key nutrients to patients with critical illness resulted in a decrease in infectious complications when compared with patients receiving standard nutritional support and a significant reduction in overall hospital stay. Similar results were documented in patients with gastrointestinal cancer. However, there were no differences between patient groups for either pneumonia or death. CONCLUSIONS This meta-analysis has demonstrated that nutritional support supplemented with key nutrients results in a significant reduction in the risk of developing infectious complications and reduces the overall hospital stay in patients with critical illness and in patients with gastrointestinal cancer. However, there is no effect on death. These data have important implications for the management of such patients.

Abstract
BACKGROUND: Malnutrition is common in patients with esophageal and esophagogastric cancer. Compared to patients with other digestive and extradigestive neoplasia, the highest incidence (78.9%) was found in those with esophageal cancer. Malnutrition is associated with postoperative complications, increased morbidity, and prolonged hospital stays. METHODS: The authors review the impact and causes of malnutrition in esophageal cancer patients and present strategies that can be used to preserve or restore the nutritional status in this patient population throughout treatment. RESULTS: Patients usually are unable to sustain weight on oral intake alone and require additional means of nutritional support. Several methods can be used to provide nutritional care to the esophageal cancer patient, such as diet modification, oral supplementation, and enteral or parenteral nutrition. The enteral route is preferred due to preservation of gut integrity, reduced risk of complications, and less expense. In terminally ill patients, minimal nutritional intervention may be all that is needed to achieve patient comfort. CONCLUSIONS: In order to improve clinical outcomes and the quality of life for patients with esophageal and esophagogastric cancers, the extent of malnutrition must be identified and treated.

Abstract
The unusual amino acid composition of acute phase proteins may be relevant to our understanding of the mechanism of tissue wasting in chronic inflammatory disease. During periods in which demand for amino acids outstrips dietary supply, skeletal muscle protein may be mobilized to meet this demand. An imbalance in the amino acid composition of these proteins may thus be detrimental to the body's nitrogen economy. To address this problem, we have measured the synthetic rate of fibrinogen (perhaps the major acute phase protein) and plasma amino acid profiles in a group of patients with adenocarcinoma of the pancreas and an ongoing inflammatory response (serum C-reactive protein >10 mg/L in the absence of any other obvious infective or inflammatory cause). These were also measured in a control group with no evidence of inflammation. Fibrinogen synthesis was measured after an overnight fast, using a flooding dose of 2H5-phenylalanine. The fractional rate of fibrinogen synthesis was significantly elevated in the cancer group compared with healthy controls [39.3 (20.0-49.9) and 21.9 (13.2-37.7) %/d, respectively; median (range), P < 0.05]. The absolute rate of fibrinogen synthesis was also elevated [84 (33-143) and 26 (15-43) mg/(kg.d), respectively; median (range), P < 0.01]. We calculated that, in cancer patients with anorexia-cachexia (i.e., documented ongoing weight loss in the absence of an obvious cause such as obstruction or malabsorption), aromatic amino acid supply (predominantly tryptophan) most limits fibrinogen synthesis from skeletal muscle reserves. Demand for the nonessential amino acids serine and glycine was elevated. Assuming that tryptophan is limiting, up to 2.6 g muscle protein ( approximately 12 g skeletal muscle tissue) may be wasted to synthesize 1 g fibrinogen. Interpretation of the observation that circulating free tryptophan concentrations were significantly reduced in the cancer patients will have to await flux measurements. The metabolic changes accompanying the inflammatory response suggest that down-regulation of this process may be beneficial.

Abstract
OBJECTIVE The purpose of this study was to determine the effect of glucagon or placebo on the rate of tumor fractional protein synthesis in situ in patients with localized rectal cancer who were not malnourished, demonstrated normal glucagon concentrations, and could therefore be used as a model to study the glucagon effect. SUMMARY BACKGROUND DATA Cancer cachexia is associated with an increased concentration of counterregulatory hormones, including glucagon. This altered hormonal milieu may not only contribute to malnutrition, but also promote tumor growth, because previous experimental work suggests that glucagon can cause human colorectal tumor cells to proliferate. Corresponding mechanisms in vivo have, thus far, not been investigated. METHODS Advanced mass spectrometry techniques (capillary gas chromatography [GC]/combustion isotope ratio mass spectrometry [IRMS]) were used to determine directly the incorporation rate of 1-[13C]-leucine into tissue protein. Because GC/IRMS requires only a small sample volume, three consecutive endoscopic biopsies could be obtained from the same tumor to determine isotopic enrichments at baseline, after a 4-hour glucagon infusion (3 ng/kg/min), or after placebo. RESULTS In patients with localized rectal cancer, glucagon caused the tumor fractional protein synthetic rate to double (2.25+/-0.49 %/hr, p < 0.05 vs. 1.16+/-0.30 basal). In contrast, tumor protein synthesis declined over time in controls (placebo) (0.67+/-0.09 %/hr, p < 0.05 vs. 1.11+/-0.16 basal). CONCLUSIONS Tumor protein synthesis and growth can be stimulated by glucagon in situ. Therefore, elevated glucagon concentrations in cachectic cancer patients should be considered detrimental and attempts made to prevent this specific response of the body to the malignant disease.

Abstract
BACKGROUND Current methods to predict survival duration of patients with pancreatic cancer are limited. The aim of this study was to determine whether certain nutritional indices and the acute-phase protein response are prognostic factors independent of disease stage for patients with unresectable pancreatic cancer. METHODS Variables at the time of diagnosis of 102 patients with unresectable pancreatic cancer were entered into a Cox's proportional hazards model. Included in the analysis were the serum concentration of C-reactive protein (CRP) and albumin, the extent of weight loss, age, sex, and disease stage (International Union Against Cancer criteria). RESULTS A multivariate analysis in which each factor was adjusted for the influence of the other factors revealed the patient age, disease stage, serum albumin, and serum CRP to be independent predictors of survival. The presence of an acute-phase protein response was the most significant independent predictors of survival duration. The median survival of those with an acute-phase protein response (CRP > 10 mg/L, n = 45) was 66 days compared with 222 days for those with no acute-phase protein response (n = 57, P = 0.001, Mann-Whitney U test). CONCLUSION The acute-phase protein response is a useful prognostic indicator for patients with unresectable pancreatic cancer. Moreover, the metabolic disturbances associated with an acute-phase protein response of patients with pancreatic cancer may be a worthwhile therapeutic target.

Abstract
Reduced food intake is probably the major cause of continuing weight loss in cancer patients. Therefore, agents which stimulate food intake may be of significant benefit to such patients. To examine this, a randomized double-blind placebo controlled study of megestrol acetate was carried out. 38 gastrointestinal cancer patients with weight loss (8-43% of pre-illness stable weight) were entered into the study. 26 were evaluable at 6 weeks and 21 at 12 weeks. Clinical details, serum biochemistry and haematology were examined at 6 and 12 weeks and total body water, total body potassium at 12 weeks after the baseline assessment. There was no significant weight change in either group over the 6 or 12 weeks. Furthermore, there was no significant difference in total body water, total body potassium, blood biochemistry or haematology between the groups over the study period. It does not appear that megestrol acetate at a dose of 480 mg/day results in weight gain in advanced gastrointestinal cancer patients with weight loss.

Abstract
Cancer cachexia is a complex syndrome characterized primarily by diminished nutrient intake and progressive tissue depletion that is manifest clinically as anorexia and host weight loss. The gradual loss of host protein stores is central to this process. This review outlines the techniques that have been used to evaluate human amino acid metabolism, their application in patients with cancer cachexia, and possible therapeutic interventions designed to overcome alterations in host protein and amino acid metabolism associated with malignant cachexia. The techniques of nitrogen balance and 3-methylhistidine excretion provide indirect estimates of overall nitrogen metabolism and skeletal muscle myofibrillar protein breakdown. Measurement of circulating amino acid concentrations, particularly when combined with assessment of arterial-venous differences and regional amino acid balance allows for investigation of interorgan amino acid metabolism. One of the most significant advances in in vivo amino acid metabolic research has been the development of labeled amino acid tracer studies to evaluate whole body and regional amino acid kinetics. The use of stable and unstable amino acid isotopes in these techniques is reviewed in detail. Virtually all of these techniques have now been employed in the evaluation of human cancer cachexia. The results of studies evaluating amino acid concentrations, regional amino acid balance, and 3-methylhistidine excretion are summarized. The use of regional and whole body kinetic studies in cancer cachexia are reviewed extensively. Most investigators have observed increased rates of whole body protein turnover, synthesis, and catabolism in both weight-stable and weight-losing cancer patients. Some studies have suggested a relationship between the extent of disease and the degree of aberration in amino acid kinetic parameters. Investigators have attempted to reverse some of these alterations by provision of substrate (nutritional support) or administration of specific pharmacologic or anabolic agents such as hydrazine sulfate, insulin, growth hormone, and beta-2 agonists. The role of total parenteral nutrition (TPN) in cancer and its effects on protein and amino acid kinetics and tumor growth are addressed. The possible benefits of specific amino acid nutritional formulations with increased branched chain amino acids, arginine, and glutamine are reviewed. Although many of these approaches appear promising, significant impact on clinically definable parameters remains to be demonstrated. A better understanding of the underlying protein catabolic mechanisms of cancer cachexia will likely lead to more effective therapies to reverse the protein calorie malnutrition associated with cancer cachexia.

Abstract
In vivo colonization by different Lactobacillus strains on human intestinal mucosa of healthy volunteers was studied together with the effect of Lactobacillus administration on different groups of indigenous bacteria. A total of 19 test strains were administered in fermented oatmeal soup containing 5 x 10(6) CFU of each strain per ml by using a dose of 100 ml of soup per day for 10 days. Biopsies were taken from both the upper jejunum and the rectum 1 day before administration was started and 1 and 11 days after administration was terminated. The administration significantly increased the Lactobacillus counts on the jejunum mucosa, and high levels remained 11 days after administration was terminated. The levels of streptococci increased by 10- to 100-fold in two persons, and the levels of sulfite-reducing clostridia in the jejunum decreased by 10- to 100-fold in three of the volunteers 1 day after administration was terminated. In recta, the anaerobic bacterium counts and the gram-negative anaerobic bacterium counts decreased significantly by the end of administration. Furthermore, a decrease in the number of members of the Enterobacteriaceae by 1,000-fold was observed on the rectal mucosa of two persons. Randomly picked Lactobacillus isolates were identified phenotypically by API 50CH tests and genotypically by the plasmid profiles of strains and by restriction endonuclease analysis of chromosomal DNAs.(ABSTRACT TRUNCATED AT 250 WORDS)
