Management of diet in gastrointestinal cancer

Prognostic Nutritional Index Correlates with Liver Function and Prognosis in Chronic Liver Disease Patients

The Prognostic Nutritional Index (PNI) is widely recognized as a screening tool for nutrition. We retrospectively examined the impact of PNI in patients with chronic liver disease (CLD, n = 319, median age = 71 years, 153 hepatocellular carcinoma (HCC) patients) as an observational study. Factors associated with PNI < 40 were also examined. The PNI correlated well with the albumin-bilirubin (ALBI) score and ALBI grade. The 1-year cumulative overall survival rates in patients with PNI ≥ 40 (n = 225) and PNI < 40 (n = 94) were 93.2% and 65.5%, respectively (p < 0.0001). In patients with (p < 0.0001) and without (p < 0.0001) HCC, similar tendencies were found. In the multivariate analysis, hemoglobin (p = 0.00178), the presence of HCC (p = 0.0426), and ALBI score (p < 0.0001) were independent factors linked to PNI < 40. Receiver operating characteristic (ROC) curve analysis based on survival for the PNI yielded an area under the ROC curve of 0.79, with sensitivity of 0.80, specificity of 0.70, and an optimal cutoff point of 42.35. In conclusion, PNI can be a predictor of nutritional status in CLD patients. A PNI of <40 can be useful in predicting the prognosis of patients with CLD.

Accurate SARC-F Score in Patients with Liver Disease

SARC-F is a well-accepted screening tool for sarcopenia. A SARC-F value of 1 point is reported to be more discriminating in identifying sarcopenia than 4 points (recommended cutoff point). The prognostic impact of the SARC-F score was investigated in patients with liver disease (LD, n = 269, median age = 71 years, 96 hepatocellular carcinoma (HCC) cases). Factors associated with SARC-F ≥ 4 points and SARC-F ≥ 1 point were also examined. In the multivariate analysis, age (p = 0.048), and Geriatric Nutritional Risk Index (GNRI) score (p = 0.0365) were significant factors linked to SARC-F ≥ 1 point. In our patients with LD, the SARC-F score is well correlated with the GNRI score. The 1-year cumulative overall survival ratio in patients with SARC-F ≥ 1 (n = 159) and SARC-F 0 (n = 110) was 78.3% and 90.1% (p = 0.0181). After excluding 96 HCC cases, similar tendencies were found (p = 0.0289). In the receiver operating curve (ROC) analysis based on the prognosis for the SARC-F score, the area under the ROC was 0.60. The sensitivity was 0.57, the specificity was 0.62, and the optimal cutoff point of the SARC-F score was 1. In conclusion, sarcopenia in LDs can be affected by nutritional conditions. A SARC-F score of ≥1 is more useful than a score of 4 in predicting the prognosis of patients with LD.

Cancer cachexia as a blueprint for treating obesity

Effective pharmacological treatments to achieve significant and sustained weight loss in obese individuals remain limited. Here, we apply a 'reverse engineering' approach to cancer cachexia, an extreme form of dysregulated energy balance resulting in net catabolism. We discuss three phenotypic features of the disease, summarize the underlying molecular checkpoints, and explore their translation to obesity research. We then provide examples for established pharmaceuticals, which follow a reverse engineering logic, and propose additional targets that may be of relevance for future studies. Finally, we argue that approaching diseases from this perspective may prove useful as a generic strategy to fuel the development of innovative therapies.

Effectiveness of combined nutrition and exercise interventions on body weight, lean mass, and fat mass in adults diagnosed with cancer: a systematic review and meta-analysis

CONTEXT

Changes in body weight and composition (fat and lean mass) are prominent side effects of cancer treatment. Nutrition and exercise interventions are both key strategies to protect against these adverse effects, yet their impact when combined has not been comprehensively reviewed in adults with cancer.

OBJECTIVE

This systematic review and meta-analysis aims to assess the effects of combined nutrition and exercise interventions on body weight and composition in adults with cancer.

DATA SOURCES

Four databases were searched until January 2021. Combined nutrition and exercise randomized controlled trials that detailed the nutrition and exercise prescription and reported body weight and composition outcomes were eligible.

DATA EXTRACTION

Risk of bias was assessed through the Cochrane Collaboration tool. The number of participants, mean values, and standard deviations of the outcome variables were extracted. Mean differences (MDs) were pooled using random-effects models. Predetermined subgroup analyses included cancer type, intervention intent, exercise modality, and use of behavior change strategies.

DATA ANALYSIS

Twenty-three RCTs were included. Nutrition plus exercise interventions significantly reduced body weight (MD -  2.13 kg; 95%CI, - 3.07 to - 1.19), fat mass (MD - 2.06 kg; 95%CI, - 3.02 to - 1.09), and lean mass (MD - 0.43; 95%CI, - 0.82 to - 0.04). Subgroup analyses in women with breast cancer showed that weight loss interventions and interventions incorporating behavior change strategies significantly reduced body weight and fat mass but also reduced lean mass. Interventions aiming to maintain body weight showed no changes in body weight, as intended.

CONCLUSION

Combined nutrition and exercise interventions successfully reduce body weight and fat mass in adults with cancer but also reduce lean mass. In contrast, weight loss-focused interventions are associated mostly with reduced lean mass.

Effect of Enteral Immunonutrition in Patients Undergoing Surgery for Gastrointestinal Cancer: An Updated Systematic Review and Meta-Analysis

Background

The efficacy of enteral immunonutrition (EIN) in patients undergoing gastrointestinal cancer surgery remains debatable. This meta-analysis aimed to investigate the effectiveness of EIN administration in patients undergoing surgery for gastrointestinal cancer.

Methods

From January 2000 to January 2022, PubMed, EMBASE, Cochrane Library, and Web of Science were thoroughly searched for randomized controlled trials (RCTs) with EIN versus standard diet or no supplement in patients undergoing surgery for gastrointestinal cancer. Overall complications and infectious complications were the primary outcomes. The secondary results were non-infectious complications, mortality, length of hospital stay, and enteral nutrition-related complications.

Results

Thirty-five studies reporting 3,692 patients undergoing surgery for gastrointestinal cancer (including gastric cancer, colorectal cancer, esophageal cancer, periampullary cancer, or pancreatic cancer) were included. Compared with the control group, EIN group had a significantly decreased incidence of overall complications (RR = 0.79, p < 0.001). Infectious complications in patients who received EIN were considerably lower than in the control group (RR = 0.66, p < 0.001). Compared to the control group, the incidence of surgical site infection, abdominal abscess, anastomotic leakage, bacteremia, duration of systemic inflammatory response syndrome (SIRS), and duration of antibiotic therapy was significantly lower in the specific infectious complications treated with EIN. Still, there was no significant difference between the two groups with other infectious complications. Moreover, a substantial shortening in the length of hospital stay was shown in EIN group compared with the control group. Still, no significant effect of EIN was demonstrated in non-infectious complicatios and mortality. The enteral nutrition-related complications had no significant difference between two groups.

Conclusions

EIN is safe and effective in reducing overall complications, infectious complications, and hospital stay in patients undergoing gastrointestinal cancer surgery (including gastric cancer, colorectal cancer, esophageal cancer, periampullary cancer, or pancreatic cancer).

Comparison of the Suitability Between NRS2002 and MUST as the First-Step Screening Tool for GLIM Criteria in Hospitalized Patients With GIST

Objective

The Global Leader Initiative on Malnutrition (GLIM) criteria have been recommended for malnutrition diagnosis recently, for which the first step is malnutrition risk screening with any validated tool. This study aims to investigate the incidence of malnutrition risk in gastrointestinal stromal tumor (GIST) inpatients and compare the suitability of Nutritional Risk Screening 2002 (NRS2002) and Malnutrition Universal Screening Tool (MUST) as the first-step screening tool for GLIM criteria.

Methods

We retrospectively analyzed the clinical data of GIST inpatients in our hospital from January 2015 to December 2019. NRS2002 and MUST were used to screen malnutrition risk at the time of admission. The diagnostic consistency of these two tools with GLIM criteria for malnutrition was analyzed, and the predictive performance of both tools for the length of hospital stay and the occurrence of complications was also evaluated in surgical and non-surgical inpatients.

Results

A total of 269 GIST inpatients were included in this study, of which 45.7 and 40.9% were at malnutrition risk determined by NRS2002 and MUST, respectively. In non-surgical inpatients, NRS2002 and MUST had similar diagnostic consistency with GLIM criteria in sensitivity (93.0 vs. 97.7%), specificity (81.1 vs. 81.1%), and Kappa value (K = 0.75 vs. 0.80), and high nutritional risk classified by NRS2002 and malnutrition identified by GLIM criteria were found to be associated with the length of hospital stay. In surgical inpatients, MUST had better diagnostic consistency with GLIM criteria in sensitivity (86.1 vs. 53.5%) and Kappa value (K = 0.61 vs. 0.30) than NRS2002, but no factors were found associated with the length of postoperative hospital stay or the occurrence of complications.

Conclusion

The malnutrition risk is common in GIST inpatients. NRS2002 is more suitable than MUST for the first-step risk screening of the GLIM scheme in non-surgical inpatients, considering its better performance in screening malnutrition risk and predicting clinical outcomes. MUST was found to have good diagnostic consistency with GLIM criteria for malnutrition in both non-surgical and surgical GIST inpatients, and further studies need to be conducted to investigate its predictive performance on clinical outcomes.

Grip Strength in Patients with Gastrointestinal Diseases

We sought to elucidate factors contributing to the grip strength (GS) decline in patients with gastrointestinal diseases (Ga-Ds, n = 602, 379 males, median age = 72 years). The GS decline in males and females was defined as <28 kg and <18 kg, respectively, following the current Asian guidelines. The median GS (male) was 28.8 kg, and GS decline (male) was found in 169 patients (44.6%). The median GS (female) was 17.5 kg, and GS decline (female) was found in 122 patients (54.7%). Advanced cancer was identified in 145 patients (24.1%). In terms of the univariate analysis of parameters of the GS decline, age (p < 0.0001), gender (p = 0.0181), body mass index (BMI, p = 0.0002), ECOG-PS (p < 0.0001), SARC-F score (p < 0.0001), hemoglobin value (p < 0.0001), total lymphocyte count (p < 0.0001), serum albumin value (p < 0.0001), C reactive protein (CRP) value (p < 0.0001), and estimated glomerular filtration rate were statistically significant. In terms of the multivariate analysis, age (p < 0.0001), BMI (p = 0.0223), hemoglobin value (p = 0.0186), serum albumin value (p = 0.0284), the SARC-F score (p = 0.0003), and CRP value (p < 0.0001) were independent parameters. In conclusion, the GS decline in patients with Ga-Ds is closely associated with not only the primary factor (i.e., aging) but also secondary factors such as inflammatory factors and nutritional factors.

The Relevance in the Neutrophil to Lymphocyte Ratio and the SARC-F Score in Gastrointestinal Diseases

We sought to clarify the relevance in the neutrophil to lymphocyte ratio (NLR) and the SARC-F score in patients with gastrointestinal diseases (G-Ds, n = 672, median age = 73 years). Univariate and multivariate analysis for the SARC-F score were performed. Advanced malignancy was identified in 162 patients (24.1%). The median of NLR for all cases was 2.65. The median of NLR in ECOG-PS 0 (n = 436), 1 (n = 128), 2 (n = 49) and 3 or 4 (n = 59) was 2.26, 2.97, 4.41 and 5.99 (overall p < 0.0001). NLR had a significant correlation with the SARC-F score (r = 0.54, p < 0.0001). The median of NLR in the SARC-F score ≥4 (recommended value for sarcopenia, n = 84) and <4 (n = 588) was 5.87 and 2.48 (p < 0.0001). In all subgroup analyses, similar trends were seen. In the multivariate analysis, ECOG-PS (p < 0.0001) and NLR (p < 0.0001) were independent factors, while age had a trend for significance (p = 0.0686). In conclusion, we would like to emphasize the usefulness of NLR, a simple marker assessed only by blood tests, in predicting the possibility for sarcopenia by the SARC-F in G-Ds.

The Relationship between the SARC-F Score and the Controlling Nutritional Status Score in Gastrointestinal Diseases

We sought to examine the relationship between the SARC-F score and the Controlling Nutritional Status (CONUT) score in patients with gastrointestinal diseases (GDs, n = 735, median age = 71 years, and 188 advanced cancer cases). The SARC-F score ≥ 4 (highly suspicious of sarcopenia) was found in 93 cases (12.7%). Mild malnutritional condition was seen in 310 cases (42.2%), moderate in 127 (17.3%) and severe in 27 (3.7%). The median SARC-F scores in categories of normal, mild, moderate and severe malnutritional condition were 0, 0, 1 and 1 (overall p < 0.0001). The percentage of SARC-F score ≥ 4 in categories of normal, mild, moderate and severe malnutritional condition were 4.4%, 12.9%, 26.8% and 25.9% (overall p < 0.0001). The SARC-F score was an independent factor for both the CONUT score ≥ 2 (mild, moderate or severe malnutrition) and ≥5 (moderate or severe malnutrition). In the receiver operating characteristic (ROC) curve analysis for the CONUT score ≥ 2, C reactive protein (CRP) had the highest area under the ROC (AUC = 0.70), followed by the SARC-F score (AUC = 0.60). In the ROC analysis for the CONUT score ≥ 5, CRP had the highest AUC (AUC = 0.79), followed by the SARC-F score (AUC = 0.63). In conclusion, the SARC-F score in patients with GDs can reflect malnutritional status.

Prognostic Impact of the SARC-F Score in Gastrointestinal Advanced Cancers

Simple Summary

There have been few reports with regard to the relevance between the SARC-F score and the prognosis in patients with gastrointestinal advanced cancers, and we aimed to elucidate these issues (n = 421, median age = 73 years). During the follow-up period, 145 patients (34.4%) died. The 1-year cumulative overall survival rate in patients with SARC-F ≥ 4 (recommended cutoff point, n = 103) and SARC-F < 4 (n = 318) was 33.9% and 61.6% (p < 0.0001). In the multivariate analysis for the overall survival, total lymphocyte count ≥ 1081/μL (p = 0.0014), the SARC-F score ≥ 4 (p = 0.0096), Glasgow prognostic score 1 (p = 0.0147) and 2 (p < 0.0001), ECOG-PS 2 (p < 0.0001), and 3 (p < 0.0001) and 4 (p < 0.0001) were independent predictors. In the receiver operating characteristic curve analysis on the prognostic value of the SARC-F score, the sensitivity/specificity was 0.59/0.70, and the best cutoff point of the SARC-F score was two. The SARC-F score appears to be useful in patients with gastrointestinal advanced malignancies.

Abstract

We sought to elucidate the prognostic impact of the SARC-F score among patients with gastrointestinal advanced malignancies (n = 421). A SARC-F score ≥ 4 was judged to have a strong suspicion for sarcopenia. In patients with ECOG-PS 4 (n = 43), 3 (n = 61), and 0–2 (n = 317), 42 (97.7%), 53 (86.9%) and 8 (2.5%) had the SARC-F score ≥ 4. During the follow-up period, 145 patients (34.4%) died. All deaths were cancer-related. The 1-year cumulative overall survival (OS) rate in patients with SARC-F ≥ 4 (n = 103) and SARC-F < 4 (n = 318) was 33.9% and 61.6% (p < 0.0001). In the multivariate analysis for the OS, total lymphocyte count ≥ 1081/μL (p = 0.0014), the SARC-F score ≥ 4 (p = 0.0096), Glasgow prognostic score (GPS) 1 (p = 0.0147, GPS 0 as a standard), GPS 2 (p < 0.0001, GPS 0 as a standard), ECOG-PS 2 (p < 0.0001, ECOG-PS 0 as a standard), ECOG-PS 3 (p < 0.0001, ECOG-PS 0 as a standard), and ECOG-PS 4 (p < 0.0001, ECOG-PS 0 as a standard) were independent predictors. In the receiver operating characteristic curve analysis on the prognostic value of the SARC-F score, the sensitivity/specificity was 0.59/0.70, and best cutoff point of the SARC-F score was two. In conclusion, the SARC-F score is useful in patients with gastrointestinal advanced malignancies.

Comparison of SARC-F Score among Gastrointestinal Diseases

SARC-F is a screening tool for sarcopenia. We sought to compare the SARC-F scores of patients with different gastrointestinal diseases (n = 1282 (762 males): upper gastrointestinal disease (UGD, n = 326), lower gastrointestinal disease (LGD, n = 357), biliary and pancreatic disease (BPD, n = 416), and liver disease (LD, n = 183)). Factors associated with SARC-F ≥4 points (highly suspicious of sarcopenia) were also examined. The median age was 71 years. Patients with SARC-F ≥4 points were found in 197 (15.4%). Advanced cancer was found in 339 patients (26.4%). The proportion of SARC-F ≥4 points in groups of UGD, LGD, BPD, and LD were 17.5% (57/326) in UGD, 12.0% (43/357) in LGD, 17.3% (72/416) in BPD, and 13.7% (25/183) in LD, respectively (overall p = 0.1235). In patients with and without advanced cancer, similar tendencies were observed. In the multivariate analysis, age (p < 0.0001), gender (p = 0.0011), serum albumin (p < 0.0001), lymphocyte count (p = 0.0019), C reactive protein (p = 0.0197), and the presence of advanced cancer (p = 0.0424) were significant factors linked to SARC-F ≥4 points. In patients with advanced cancer, SARC-F scores correlated well with their Glasgow prognostic scores. In conclusion, sarcopenia in gastrointestinal diseases may be affected not by disease type (i.e., the primary origin of the disease) but by aging, nutritional condition, inflammatory condition, and cancer burden.

Dietary Antioxidant Capacity and Serum Inflammatory Biomarkers Levels in Cancer Survivors

This study aimed to compare the dietary intake of carotenoids, tocopherols, ascorbic acid, flavonoids, and dietary total antioxidant capacity (dTAC) and to evaluate relationship of dTAC with serum inflammatory biomarkers in patients with gastrointestinal system (GIS) and non-GIS cancer. In total, 104 adult cancer survivors (52 GIS and 52 non-GIS cancer cases) were included. 24-hour dietary recalls were obtained and dTAC was calculated on the basis of oxygen radical absorption capacity (ORAC), Trolox equivalent antioxidant capacity (TEAC), total radical-trapping antioxidant parameter (TRAP), ferric reducing antioxidant potential (FRAP), and vitamin C equivalents (VCE). Serum C-reactive protein (CRP) level, neutrophil-lymphocyte ratio (NLR), and platelet-lymphocyte ratio (PLR) were used as inflammatory biomarkers. Routinely analyzed serum CRP, neutrophil, lymphocyte, and platelet levels every day in hospital biochemistry laboratory were obtained from patients' file. There was no significant difference between patients with GIS and non-GIS cancer in terms of dietary intake of carotenoids, tocopherols, and flavonoids. While there was no significant difference between groups in terms of the mean dietary ORAC, TEAC, and FRAP, the mean TRAP of patients with GIS cancer was significantly higher than patients with non-GIS cancer. Serum inflammatory markers (CRP and NLR) were found to have an inverse relationship with dTAC.

Early Interdisciplinary Supportive Care in Patients With Previously Untreated Metastatic Esophagogastric Cancer: A Phase III Randomized Controlled Trial

PURPOSE

Effective interventions to improve prognosis in metastatic esophagogastric cancer (EGC) are urgently needed. We assessed the effect of the early integration of interdisciplinary supportive care for patients with metastatic EGC on overall survival (OS).

PATIENTS AND METHODS

An open-label, phase III, randomized, controlled trial was conducted at Peking University Cancer Hospital & Institute. Patients with previously untreated metastatic EGC were enrolled. Patients were randomly assigned (2:1) to either early interdisciplinary supportive care (ESC) integrated into standard oncologic care or standard care (SC). ESC was provided by a team of GI medical oncologists, oncology nurse specialists, dietitians, and psychologists; patients in the SC group received standard oncologic care alone. The primary end point was OS in the intention-to-treat population.

RESULTS

Between April 16, 2015, and December 29, 2017, 328 patients were enrolled: 214 in the ESC group and 114 in the SC group. At the data cutoff date of January 26, 2019, 15 (5%) patients were lost to follow-up. The median number of cycles of first-line chemotherapy was five (interquartile range [IQR], 4-7) in the ESC group and four (IQR, 2-6) in the SC group. The median OS was 14.8 months (95% CI, 13.3 to 16.3) in the ESC group and 11.9 months (95% CI, 9.6 to 13.6) in the SC group (hazard ratio, 0.68; 95% CI, 0.51 to 0.9; P = .021).

CONCLUSION

The early integration of interdisciplinary supportive care is an effective intervention with survival benefits for patients with metastatic EGC. Further optimization and standardization are warranted.
