The role of cholesterol-modified prognostic nutritional index in nutritional status assessment and predicting survival after liver resection for hepatocellular carcinoma

Malnutrition, which is often underestimated in patients with hepatocellular carcinoma (HCC), has a proven adverse effect on survival rates. The purpose of this study was to verify the effectiveness of the cholesterol-modified prognostic nutritional index (CPNI) in determining the nutritional status and predicting overall survival (OS) and recurrence-free survival (RFS) in patients with HCC by comparing it with several other nutritional indicators. This retrospective single-center study enrolled 1450 consecutive HCC patients who underwent curative liver resection from January 2015 to November 2019. We evaluated the prognostic significance of several nutritional indicators, including CPNI, the controlling nutritional status (CONUT), the nutritional risk index (NRI), and the prognostic nutritional index (PNI), by applying time-dependent receiver operating characteristic (ROC) curves, Kaplan-Meier survival analysis, and Cox proportional hazards regression analysis. Among several objective nutrition evaluations (including CPNI, CONUT, NRI, and PNI), CPNI demonstrated the greatest prognostic predictive power for predicting OS. Meanwhile, CPNI demonstrated marginally higher accuracy in predicting RFS compared to PNI, and significantly outperformed CONUT and NRI. Univariate and multivariate analyses suggested that CPNI was an independent risk factor for the OS and RFS of patients with HCC undergoing curative liver resection. In most subgroups, malnutrition as identified by CPNI demonstrates strong stratification ability in predicting both OS and RFS. CPNI serves as an accurate and stable instrument for evaluating nutritional status and forecasting survival outcomes in HCC patients following liver resection, which has the potential to markedly influence clinical decision-making processes and the management of patient care.

A cross-sectional survey study on the correlation analysis of nutritional status and intestinal flora in patients with esophageal cancer

Objective

This study aims to examine the nutritional status of individuals diagnosed with esophageal cancer and compare the nutritional indicators and intestinal flora between malnourished and non-malnourished patients. The findings aim to contribute to the early prevention of malnutrition and the development of interventions targeting the intestinal flora to treat esophageal cancer.

Methods

An 80-patient sample of hospitalized individuals with esophageal cancer was selected from the radiotherapy department of our hospital between July 2021 and July 2022 to evaluate NRS2002 scores and PG-SGA scores. This cross-sectional analysis aimed to examine the disparities in dietary nutrient intake, blood indicators, body composition, and fecal intestinal flora between malnourished and non-malnourished patients with esophageal cancer. Additionally, we randomly selected 40 cases to predict and analyze the relationship between intestinal flora and malnutrition.

Results

The incidence of nutritional risk and malnutrition in patients with esophageal cancer was 62.5% and 60%, respectively. The low intake of carbohydrates and dietary fiber in the malnutrition group was statistically significant compared to those in the non-malnutrition group (P < 0.05). The albumin (ALB) level was lower in the malnutrition group than in the non-malnutrition group, while the C-reactive protein (CRP) level was higher; these differences were also statistically significant (P < 0.05). The basal metabolic rate, phase angle, body cell mass, muscle mass, skeletal muscle index, and fat-free mass index in the malnutrition group all decreased compared to the non-malnutrition group. The extracellular water/total body water was higher than that in the non-malnutrition group, which was also statistically significant (P < 0.05). As shown by 16S rDNA sequencing of fecal intestinal flora, there was no significant difference in α and β diversity between the malnutrition and non-malnutrition groups; at the genus level, significant differences were observed for Selimonas, Clostridioides, Dielma, Lactobacillus, and [Eubacterium]_siraeum_group. However, Dielma, Sellimonas, and Clostridioides were significantly lower in the malnutrition group than in the non-malnutrition group, while Anaerococcus, Atopobium, Eubacterium_siraeum_group, and Lactobacillus were significantly higher in the malnutrition group. Correlation analysis between different genera and clinical indicators showed that Lactobacillus was positively correlated with ALB, dietary energy, intracellular water/total body water (ICW/TBW), phase angle (PA), muscle mass (MM), skeletal muscle mass (SMM), body cell mass (BCM), basal metabolic rate (BMR), appendicular skeletal muscle mass (ASMM), total body water (TBW), fat-free mass index (FFMI), skeletal muscle index (SMI), fat-free mass (FFM), Weight, body mass index (BMI) (r > 0, P < 0.05), but negatively correlated with PG-SGA score, NRS2002 score, and extracellular water/total body water (ECW/TBW) (r < 0, P < 0.05). Based on PG-SGA, there was only a low accuracy for identifying nutrient deficiency (most areas under curve (AUC) values fell within 0.5 to 0.7, or even lower), with Lachnoclostridium's AUC being 0.688 (CI = 0.518-0.858) and Lactobacillus_salivarius_g_Lactobacillus's AUC being 0.257 (CI = 0.098-0.416). A KEGG functional analysis based on 16S data indicated potential differences affecting glucose metabolism pathways and the synthesis or division of DNA, influencing the onset, development, and prognosis of esophageal cancer patients.

Conclusion

Esophageal cancer patients are more likely to be malnourished. The nutritional status of these patients is closely linked to the intake of carbohydrates and fiber, albumin levels, inflammation levels, and lean body mass. Furthermore, the patient's intestinal flora composition plays a significant role in their nutritional well-being. Consequently, modulating the intestinal flora holds promise as a potential therapeutic approach for addressing malnutrition in esophageal cancer patients.

Association between risk of malnutrition defined by patient-generated subjective global assessment and adverse outcomes in patients with cancer: a systematic review and meta-analysis

OBJECTIVE

To assess the association between the risk of malnutrition, as estimated by the Patient-Generated Subjective Global Assessment (PG-SGA) numerical scores, and adverse outcomes in oncology patients.

DESIGN

Systematic review and meta-analysis.

SETTINGS

A comprehensive search was conducted in PubMed, Web of Science, Embase, CKNI, VIP, Sinomed and Wanfang databases. Studies that examined the association between the risk of malnutrition, as estimated by the PG-SGA numerical scores, and overall survival (OS) or postoperative complications in oncology patients were included. Patients were classified as low risk (PG-SGA ≤ 3), medium risk (PG-SGA 4-8) and high risk of malnutrition (PG-SGA > 8).

SUBJECT

Nineteen studies reporting on twenty articles (n 9286 patients).

RESULTS

The prevalence of medium and high risk of malnutrition ranged from 16·0 % to 71·6 %. A meta-analysis showed that cancer patients with medium and high risk of malnutrition had a poorer OS (adjusted hazard ratios (HR) 1·98; 95 % CI 1·77, 2·21) compared with those with a low risk of malnutrition. Stratified analysis revealed that the pooled HR was 1·55 (95 % CI 1·17, 2·06) for medium risk of malnutrition and 2·65 (95 % CI 1·90, 3·70) for high risk of malnutrition. Additionally, the pooled adjusted OR for postoperative complications was 4·65 (95 % CI 1·61, 13·44) for patients at medium and high risk of malnutrition.

CONCLUSIONS

The presence of medium and high risk of malnutrition, as estimated by the PG-SGA numerical scores, is significantly linked to poorer OS and an increased risk of postoperative complications in oncology patients.

Association between Controlling Nutritional Status (CONUT) Score and Body Composition, Inflammation and Frailty in Hospitalized Elderly Patients

The Controlling Nutritional Status (CONUT) score has demonstrated its ability to identify patients with poor nutritional status and predict various clinical outcomes. Our objective was to assess the association between the CONUT score, inflammatory status, and body composition, as well as its ability to identify patients at risk of frailty in hospitalized elderly patients.

METHODS

a total of 361 patients were retrospectively recruited and divided into three groups based on the CONUT score.

RESULTS

patients with a score ≥5 exhibited significantly higher levels of inflammatory markers, such as erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), Neutrophil/Lymphocytes ratio (NLR), main platelet volume (MPV), and ferritin, compared to those with a lower score. Furthermore, these patients showed unfavorable changes in body composition, including a lower percentage of skeletal muscle mass (MM) and fat-free mass (FFM) and a higher percentage of fatty mass (FM). A positive correlation was found between the CONUT score and inflammatory markers, Geriatric Depression Scale Short Form (GDS-SF), and FM. Conversely, the Mini Nutritional Assessment (MNA), Mini-Mental Status Examination, activity daily living (ADL), instrumental activity daily living (IADL), Barthel index, FFM, and MM showed a negative correlation. Frailty was highly prevalent among patients with a higher CONUT score. The receiver operating characteristic (ROC) curve demonstrated high accuracy in identifying frail patients (sensitivity).

CONCLUSIONS

a high CONUT score is associated with a pro-inflammatory status as well as with unfavorable body composition. Additionally, it is a good tool to identify frailty among hospitalized elderly patients.

The Effects of Omega-3 Fatty Acids Supplementation on Inflammatory Factors in Cancer Patients: A Systematic Review and Dose-Response Meta-Analysis of Randomized Clinical Trials

Until now, no study evaluated the impact of optimum intake of omega-3 fatty acids on inflammatory factors. We aimed to investigate the dose-dependent effects of omega-3 fatty acids supplementation on inflammatory factors in cancer patients. PubMed, Scopus and ISI Web of Science were searched until July 2022 to find randomized controlled trials (RCTs) for examining the efficacy of omega-3 fatty acids on inflammatory factors. Our primary outcomes were interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), C-reactive protein (CRP), and albumin. The results of 33 trials (2068 participants) revealed that each 1 g/day omega-3 fatty acids (oral/enteral) significantly reduced IL-6 (SMD: -1.17 pg/ml; 95% CI: -1.78, -0.55; p < 0.001; GRADE = moderate), and TNF-α (SMD: -2.15 pg/ml; 95% CI: -3.14, -1.16; p < 0.001; GRADE = very low). Moreover, each 0.5 g/kg/day omega-3 fatty acids (parenteral) significantly reduced TNF-α (SMD: -1.11 pg/ml; 95% CI: -2.02, -0.19; p = 0.017; GRADE = low). With moderate and very low evidence certainty, each 1 g/day of omega-3 fatty acids supplementation (oral/enteral) has a beneficial effect on IL-6 and TNF-α. Each 0.5 g/kg/day omega-3 fatty acids (parenteral) could also exert a favorable impact on TNF-α, but the certainty of the evidence was low.

Cholesterol-modified prognostic nutritional index (CPNI) as an effective tool for assessing the nutrition status and predicting survival in patients with breast cancer

BACKGROUND

Malnutrition is associated with poor overall survival (OS) in breast cancer patients; however, the most predictive nutritional indicators for the prognosis of patients with breast cancer are not well-established. This study aimed to compare the predictive effects of common nutritional indicators on OS and to refine existing nutritional indicators, thereby identifying a more effective nutritional evaluation indicator for predicting the prognosis in breast cancer patients.

METHODS

This prospective study analyzed data from 776 breast cancer patients enrolled in the "Investigation on Nutritional Status and its Clinical Outcome of Common Cancers" (INSCOC) project, which was conducted in 40 hospitals in China. We used the time-dependent receiver operating characteristic curve (ROC), Kaplan-Meier survival curve, and Cox regression analysis to evaluate the predictive effects of several nutritional assessments. These assessments included the patient-generated subjective nutrition assessment (PGSGA), the global leadership initiative on malnutrition (GLIM), the controlling nutritional status (CONUT), the nutritional risk index (NRI), and the prognostic nutritional index (PNI). Utilizing machine learning, these nutritional indicators were screened through single-factor analysis, and relatively important variables were selected to modify the PNI. The modified PNI, termed the cholesterol-modified prognostic nutritional index (CPNI), was evaluated for its predictive effect on the prognosis of patients.

RESULTS

Among the nutritional assessments (including PGSGA, GLIM, CONUT, NRI, and PNI), PNI showed the highest predictive ability for patient prognosis (time-dependent ROC = 0.58). CPNI, which evolved from PNI, emerged as the superior nutritional index for OS in breast cancer patients, with the time-dependent ROC of 0.65. It also acted as an independent risk factor for mortality (p < 0.05). Moreover, the risk of malnutrition and mortality was observed to increase gradually among both premenopausal and postmenopausal age women, as well as among women categorized as non-overweight, overweight, and obese.

CONCLUSIONS

The CPNI proves to be an effective nutritional assessment tool for predicting the prognosis of patients with breast cancer.

Prognostic significance of index (LANR) composed of preoperative lymphocytes, albumin, and neutrophils in patients with stage IB-IIA cervical cancer

BACKGROUND

The purpose of this study was to investigate the role of preoperative lymphocytes, albumin, neutrophils, and LANR in the prognosis of patients with stage IB-IIA cervical cancer (CC).

METHODS

We made a retrospective analysis of the clinical information and related materials of 202 patients with stage IB-IIA primary cervical cancer who had undergone a radical hysterectomy in the Department of Gynecology at the Affiliated Hospital of Jiangnan University between January 2017 and December 2018. The definition of LANR was as follows: LANR, lymphocyte × albumin / neutrophil. The receiver operating characteristic curve (ROC) was generated to determine the best cut-off values for these parameters, as well as the sensitivity and specificity of LANR in predicting recurrence and survival. The Kaplan-Meier method was employed to draw survival curves in our survival analysis. Univariate analysis, multifactorial analysis, and subgroup analysis were used to evaluate the prognostic significance of LANR in overall and progression-free survival.

RESULTS

The median follow-up time of the study was 55 months. In overall survival, the area under the curve for LANR was 0.704 (95% CI: 0.590-0.818, p<0.05). And in progression-free survival, the area under the curve for LANR was 0.745 (95% CI: 0.662-0.828, p<0.05). Univariate and multivariate analyses showed that the value of LANR was associated with both overall survival and progression-free survival (p< 0.05). Kaplan-Meier analysis demonstrated that OS (p< 0.001) and PFS (p< 0.001) in patients with high LANR levels were significantly higher than those with low LANR levels.

CONCLUSIONS

Our findings suggested that LANR might serve as a clinically reliable and effective independent prognostic indicator in patients with stage IB-IIA cervical cancer.

The Prognostic Nutritional Index (PNI): A New Biomarker for Determining Prognosis in Metastatic Castration-Sensitive Prostate Carcinoma

Prognostic nutritional index (PNI), which is calculated using the albumin level reflecting nutritional status and lymphocyte count reflecting immune status, is useful in showing nutritional and immunological status related to survival and prognosis in many cancers. In this study, we aimed to evaluate the biomarker potential and effect of PNI in determining the prognosis of metastatic castration-sensitive prostate cancer (mCSPC). This retrospective observational study included the complete data of 108 patients with mCPSC who were treated for at least three months between 1 January 2010, and 1 June 2021. The relationships between cancer-specific survival (CSS), overall survival (OS), progression-free survival (PFS), and PNI were evaluated. The Kaplan-Meier method for OS, PFS, and CSS, as well as univariate and multivariate Cox regression models, were used for the statistical analyses. The median age of 108 patients included in the study was 68.54 (61.05-74.19) years. A value of 49.75 was determined to be the best cut-off point for the PNI. OS (months) was found to be significantly lower in patients with low PNI (median: 34.93, 95% CI: 21.52-48.34) than in patients with high PNI (median: 65.60, 95% CI: 39.36-91.83) (p = 0.016). Patients with high PNI (median: 48.20, 95% CI: 34.66-61.73) had significantly better CSS (months) than patients with low PNI (median: 27.86, 95% CI: 24.16-31.57) (p = 0.001). There was no statistically significant difference in PFS between patients with high PNI values (median: 24.60, 95% CI: 10.15-39.05) and patients with low PNI values (median: 20.03, 95% CI: 11.06-29.03) (p = 0.092). The PNI is a good predictor of OS and CSS in patients with mCSPC. The prediction of PFS, albeit showing a trend towards significance, was not statistically significant, probably due to the small number of cases.

The pretherapeutic systemic inflammation score is a prognostic predictor for elderly patients with oesophageal cancer: a case control study

BACKGROUND

The systemic inflammation score (SIS), based on serum albumin (Alb) and lymphocyte-to-monocyte ratio (LMR), is a novel prognostic tool for some tumours. Studies indicate that the SIS can be used as a postoperative prognostic marker. However, its predictive value in elderly oesophageal squamous cell carcinoma (ESCC) patients treated with radiotherapy is unclear.

METHODS

In total, 166 elderly ESCC patients who received radiotherapy with or without chemotherapy were included. Based on different combinations of Alb and LMR levels, the SIS was divided into 3 groups, SIS = 0 (n = 79), SIS = 1 (n = 71) and SIS = 2 (n = 16). The Kaplan-Meier method was used for survival analysis. Univariate and multivariate analyses were performed to assess prognosis. Time-dependent receiver operating characteristic (t-ROC) curves were used to compare the prognostic accuracy of the SIS with that of Alb, LMR, neutrophil-to lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and systemic immune-inflammatory index (SII).

RESULTS

Decreased Alb and LMR were both associated with shorter OS, whereas a lower SIS was significantly associated with better outcomes. The OS of SIS = 0, SIS = 1 and SIS = 2 was 28.0 ± 2.9, 16.0 ± 2.8 and 10.0 ± 7.0 months, respectively (p = 0.000). Similar results were also observed for PFS. Multivariate analysis of the model with SIS revealed that the SIS was a significant independent biomarker for predicting OS and PFS. The nomogram showed that the C-index was improved to 0.677 when the SIS factor was incorporated. Furthermore, the 3-year OS rates for patients in the SIS-high group (SIS = 1 and SIS = 2) undergoing concurrent radiotherapy with a single agent (CCRT-1) and concurrent radiotherapy with two agents (CCRT-2) were 42% and 15%, respectively (p = 0.039). The t-ROC curve showed that the SIS was more sensitive than other prognostic factors for predicting overall survival.

CONCLUSION

The SIS may be a useful prognostic marker in elderly patients with ESCC receiving radiotherapy alone or chemoradiotherapy. The SIS showed a better predictive ability for OS than the continuous variable Alb and could stratify patient prognosis in different therapeutic regimens. CCRT-1 may be the best treatment for SIS-high patients.

Moderately hypo-fractionated radiotherapy combined with S-1 in inoperable locally advanced esophageal squamous cell carcinoma: A prospective, single-arm phase II study (GASTO-1045)

Purpose

We launched this prospective phase II single-arm trial on the combination of moderately hypo-fractionated radiotherapy and S-1, to explore the safety and efficacy of the new potent regimen in inoperable locally advanced esophageal squamous carcinoma (LA-ESCC) patients.

Methods

Patients with unresectable stage II-IVB LA-ESCC (UICC 2002, IVB only with metastatic celiac or supraclavicular lymph nodes) were included. Moderately hypofractionated radiotherapy (60Gy in 24 fractions) concurrent with S-1 was delivered. Meanwhile, gastrostomy tube placement by percutaneous endoscopic gastrostomy (PEG) was performed to provide nutritional support. Nutritional supplements were prescribed to meet requirements. The study outcomes included objective response rate (ORR), progression-free survival (PFS), overall survival (OS), locoregional progression-free survival (LRPFS), distant metastasis-free survival (DMFS), failure pattern, toxicities, nutritional status and treatment compliance. Endoscopy was routinely performed during post-treatment follow-up.

Results

Fifty-eight patients were included with a median follow-up of 24.4 months. The median age was 63 years (range 49-83 years) and 42 patients (72.4%) had stage III or IV diseases. The ORR was 91.3% and the CR rate was 60.3%. The estimated 2-year PFS rate and 2-year OS rate was 44.2% (95% confidence interval (CI), 31.3-57.1%) and 71.4% (95% CI, 59.4-83.4%), respectively. Radiation-induced esophagitis was the most common non-hematologic toxicity and 5 patients (8.6%) developed grade≥3 esophagitis. While, with PEG nutrition support, the nutrition-related indicators presented a clear trend toward a gradual improvement. Treatment-related death was not observed.

Conclusions

The moderately hypo-fractionated radiotherapy combined with S-1 showed promising loco-regional disease control and survival benefit in inoperable LA-ESCC patients. Meanwhile, favorable nutritional status and low incidence of severe radiation-induced esophagitis were observed with PEG nutritional support. Moreover, endoscopy examination contributed to the early detection of recurrent esophageal lesions and timely salvage treatment. The efficacy and toxicity of the combined regimen deserved further evaluation.

The advanced lung cancer inflammation index is a prognostic factor for gastrointestinal cancer patients undergoing surgery: a systematic review and meta-analysis

BACKGROUND

The advanced lung cancer inflammation index (ALI) is a comprehensive assessment indicator that can reflect inflammation and nutrition conditions. However, there are some controversies about whether ALI is an independent prognostic factor for gastrointestinal cancer patients undergoing surgical resection. Thus, we aimed to clarify its prognostic value and explore the potential mechanisms.

METHODS

Four databases including PubMed, Embase, the Cochrane Library, and CNKI were used for searching eligible studies from inception to June 28, 2022. All gastrointestinal cancers, including colorectal cancer (CRC), gastric cancer (GC), esophageal cancer (EC), liver cancer, cholangiocarcinoma, and pancreatic cancer were enrolled for analysis. We focused on prognosis most in the current meta-analysis. Survival indicators, including overall survival (OS), disease-free survival (DFS), and cancer-special survival (CSS) were compared between the high ALI group and the low ALI group. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist was submitted as a supplementary document.

RESULTS

We finally included fourteen studies involving 5091 patients in this meta-analysis. After pooling the hazard ratios (HRs) and 95% confidence intervals (CIs), ALI was found to be an independent prognostic factor for both OS (HR = 2.09, I² = 92%, 95% CI = 1.53 to 2.85, P < 0.01), DFS (HR = 1.48, I² = 83%, 95% CI = 1.18 to 1.87, P < 0.01), and CSS (HR = 1.28, I² = 1%, 95% CI = 1.02 to 1.60, P = 0.03) in gastrointestinal cancer. After subgroup analysis, we found that ALI was still closely related to OS for CRC (HR = 2.26, I² = 93%, 95% CI = 1.53 to 3.32, P < 0.01) and GC (HR = 1.51, I² = 40%, 95% CI = 1.13 to 2.04, P = 0.006) patients. As for DFS, ALI also has a predictive value on the prognosis of CRC (HR = 1.54, I² = 85%, 95% CI = 1.14 to 2.07, P = 0.005) and GC (HR = 1.37, I² = 0%, 95% CI = 1.09 to 1.73, P = 0.007) patients.

CONCLUSION

ALI affected gastrointestinal cancer patients in terms of OS, DFS, and CSS. Meanwhile, ALI was a prognostic factor both for CRC and GC patients after subgroup analysis. Patients with low ALI had poorer prognoses. We recommended that surgeons should perform aggressive interventions in patients with low ALI before the operation.

A novel nutrition-related nomogram for the survival prediction of colorectal cancer-results from a multicenter study

BACKGROUND

Precisely predicting the short- and long-term survival of patients with cancer is important. The tumor-node-metastasis (TNM) stage can accurately predict the long-term, but not short-term, survival of cancer. Nutritional status can affect the individual status and short-term outcomes of patients with cancer. Our hypothesis was that incorporating TNM stage and nutrition-related factors into one nomogram improves the survival prediction for patients with colorectal cancer (CRC).

METHOD

This multicenter prospective primary cohort included 1373 patients with CRC, and the internal validation cohort enrolled 409 patients with CRC. Least absolute shrinkage and selection operator regression analyses were used to select prognostic indicators and develop a nomogram. The concordance (C)-index, receiver operating characteristic (ROC) curve, and decision curve analysis (DCA) were used to assess the prognostic discriminative ability of the nomogram, TNM stage, Patient-Generated Subjective Global Assessment (PGSGA), and TNM stage + PGSGA models. The overall survival (OS) curve of risk group stratification was calculated based on the nomogram risk score.

RESULTS

TNM stage, radical resection, reduced food intake, activities and function declined, and albumin were selected to develop the nomogram. The C-index and calibration plots of the nomogram showed good discrimination and consistency for CRC. Additionally, the ROC curves and DCA of the nomogram showed better survival prediction abilities in CRC than the other models. The stratification curves of the different risk groups of the different TNM categories were significantly different.

CONCLUSION

The novel nomogram showed good short- and long-term outcomes of OS in patients with CRC. This model provides a personalized and convenient prognostic prediction tool for clinical applications.

Which preoperative immunonutritional index best predicts postoperative mortality after palliative surgery for malignant bowel obstruction in patients with late-stage cancer? A single-center study in Japan comparing the modified Glasgow prognostic score (mGPS), the prognostic nutritional index (PNI), and the controlling nutritional status (CONUT)

PURPOSE

To compare the utility of preoperative immunonutritional parameter measures for predicting postoperative mortality following palliative surgery (PS) for malignant bowel obstruction (MBO) in patients with late-stage cancer.

METHODS

The subjects of this retrospective study were 83 late-stage cancer patients with MBO who underwent PS between January, 2005 and December, 2018, at a single institution in Japan. We compared the modified Glasgow prognostic score (mGPS), the prognostic nutritional index (PNI), and the controlling nutritional status (CONUT) for predicting postoperative mortality following PS in these patients.

RESULTS

The most prevalent cancer in the patients who underwent PS was colorectal cancer (54.2%), followed by gastric cancer (24.1%). Postoperative complications of Clavien-Dindo classification grade ≥ 2 developed in 32 (38.6%) patients and stoma-related complications developed in 26 (31.3%) patients. There were 15 (18.1%) patients with 60-day mortality, 22 (26.5%) with 90-day mortality, and 4 (4.8%) with 30-day mortality. Multivariable analysis identified only mGPS as being associated with 60-day mortality (odds ratio, 9.387; 95% confidence interval, 0.001-4.478; p = 0.049). The overall survival of patients with a mGPS score of 2 was significantly worse than that of those with a mGPS score of < 2 (p = 0.013).

CONCLUSIONS

These results suggest that the mGPS is a good predictor not only of 60-day mortality, but also of the overall survival of patients with late-stage cancer and MBO.

Clinical Application of New Possible Biomarkers in the Assessment and Monitoring of Nutritional Status

Nutrition is directly related to human health. It is very critical to determine the nutritional status to prevent or diagnose diseases and create the right treatment plans. The determination of the nutritional status provides an early diagnosis of growth and development retardation such as malnutrition. It also plays a major role in preventing diseases that may be caused by vitamin and mineral deficiencies. It helps in the surveillance of one of the world's most serious health problems, namely “obesity.” Different ways can be used to assess nutritional status. One of the best ways to assess the nutritional and health status is to use biomarkers. A biomarker is a substance whose detection indicates a specific disease state or a response to a therapeutic intervention. Biomarkers are used to detect nutrient consumption and deficiencies as early as possible, enabling early intervention for metabolic problems. Biomarkers also allow the visualization of diseases that a person might develop or potentially have with a sample, such as blood, tissue, and urine, from the person. Health interventions such as nutritional advice will preserve health or promote rapid recovery. In this chapter, the topic of biomarkers related to nutrition and nutrient deficiencies is discussed. The existence of new possible biomarkers is also reviewed.

Nutritional risk screening in malignant tumors: a study of 375 cancer inpatients

Malnutrition is a common complication in cancer patients. It often accelerates disease progression and affects treatment outcomes. Thus, in the early census of cancer patients, examination for possible nutritional risks and correcting potential causes of malnutrition are needed to improve patients' quality of life. Our study included 375 patients diagnosed with cancer in Henan province and analyzed the relationship between nutritional risk and indicators like age, serum albumin, serum prealbumin, serum hemoglobin, tumor stage, tumor type, and inflammatory factors. We found that age, hemoglobin, and presence of gastrointestinal tumors were independent risk factors for nutritional risk. We also found significant correlation between inflammatory factors and nutritional risk in cancer patients, so as to provide new prediction indexes for clinical management of nutritional risk and dynamic changes of nutritional status.

A prognostic model using the neutrophil-albumin ratio and PG-SGA to predict overall survival in advanced palliative lung cancer

Objective

Inflammation and malnutrition are common in patients with advanced lung cancer undergoing palliative care, and their survival time is limited. In this study, we created a prognostic model using the Inflam-Nutri score to predict the survival of these patients.

Methods

A retrospective cohort study was conducted on 223 patients with advanced, histologically confirmed unresectable lung cancer treated between January 2017 and December 2018. The cutoff values of the neutrophil-albumin ratio (NAR) and Patient-Generated Subjective Global Assessment (PG-SGA) score were determined by the X-tile program. Least absolute shrinkage and selection operator (LASSO) Cox regression and multivariate Cox regression analysis were performed to identify prognostic factors of overall survival (OS). We then established a nomogram model. The model was assessed by a validation cohort of 72 patients treated between January 2019 and December 2019. The predictive accuracy and discriminative ability were assessed by the concordance index (C-index), a plot of the calibration curve and risk group stratification. The clinical usefulness of the nomogram was measured by decision curve analysis (DCA).

Results

The nomogram incorporated stage, supportive care treatment, the NAR and the PG-SGA score. The calibration curve presented good performance in the validation cohorts. The model showed discriminability with a C-index of 0.76 in the training cohort and 0.77 in the validation cohort. DCA demonstrated that the nomogram provided a higher net benefit across a wide, reasonable range of threshold probabilities for predicting OS. The survival curves of different risk groups were clearly separated.

Conclusions

The NAR and PG-SGA scores were independently related to survival. Our prognostic model based on the Inflam-Nutri score could provide prognostic information for advanced palliative lung cancer patients and physicians.

Taiwan Society of Colon and Rectum Surgeons (TSCRS) Consensus for Anti-Inflammatory Nutritional Intervention in Colorectal Cancer

Malnutrition and systemic inflammatory response (SIR) frequently occur in patients with colorectal cancer (CRC) and are associated with poor prognosis. Anti-inflammatory nutritional intervention is not only a way to restore the malnourished status but also modulate SIR. Nine experts, including colorectal surgeons, physicians and dieticians from 5 hospitals geographically distributed in Taiwan, attended the consensus meeting in Taiwan Society of Colon and Rectum Surgeons for a 3-round discussion and achieved the consensus based on a systematic literature review of clinical studies and published guidelines. The consensus recommends that assessment of nutritional risk and SIR should be performed before and after CRC treatment and appropriate nutritional and/or anti-inflammatory intervention should be adapted and provided accordingly.

Effect of chocolate on older patients with cancer in palliative care: a randomised controlled study

Background

Older advanced stage cancer patients, with changes in nutritional status, represent an important demand for palliative care. The aim was to determine the effects of 4 weeks of chocolate consumption on the nutritional status of older cancer patients in palliative care.

Methods

Older cancer patients in palliative care with ambulatory (n = 46) monitoring were randomized to control (CG, n = 15), intervention with 55% cocoa chocolate (IG1, n = 16) and intervention with white chocolate (IG2, n = 15) groups and evaluated before and after 4 weeks for nutritional status (primary outcome), evaluated by the Mini Nutritional Assessment tool (MNA). Food consumption, anthropometry, body composition, laboratory parameters and quality of life (QL) with the European Organization for the Research and Treatment of Cancer instrument were also evaluated.

Results

IG1 progressed with increased screening (estimated difference [95% CI]: − 1.3 [− 2.2;-0.4], p < 0.01), and nutritional (estimated difference [95% CI]: − 1.3 [− 2.5;-0.1], p = 0.04) scores on the MNA, with no change in anthropometry and body composition. Regarding antioxidant capacity, reduced glutathione levels increased (estimated difference [95% CI]: − 0.8 [− 1.6;-0.02], p = 0.04) and malondealdehyde levels decreased in IG2 (estimated difference [95% CI]:+ 4.9 [+ 0.7;+ 9.1], p = 0.02). Regarding QL, functionality improved in IG1, with higher score in the functional domain (estimated difference [95% CI]:-7.0 [− 13.3;-0.7], p = 0.03).

Conclusions

The consumption of chocolate with a greater cocoa content may contribute to the improvement of the nutritional status and functionality among older cancer patients in palliative care. The consumption of white chocolate was associated with improved oxidative stress.

Association Between the Nutritional Risk and the Survival Rate in Newly Diagnosed GIST Patients

Background: Currently, the incidence of gastrointestinal stromal tumors (GIST) is increasing rapidly worldwide. Malnutrition may increase the risk of perioperative complications and affect the prognosis of patients. However, previous studies on the nutritional status of GIST patients and its impact on prognosis are limited. Therefore, this study aims to explore the incidence of malnutrition in newly diagnosed GIST patients, the proportion of participants in need of nutritional intervention, and the relationship between nutritional status and overall survival (OS). Methods: We retrospectively analyzed the clinical data of GIST patients treated in our hospital from January 2014 to January 2018. Nutritional Risk Screening 2002 (NRS2002) and Patient-Generated Subjective Global Assessment (PG-SGA) were used to assess the nutritional status of all patients. This study was to investigate the clinical significance of PG-SGA by analyzing the relationship between PG-SGA score and OS. Results: A total of 1,268 newly diagnosed GIST patients were included in this study, of which 77.76% were at risk of malnutrition (NRS2002 score ≥ 3), and the incidence of malnutrition was 10.09% (PG-SGA score ≥ 4). Meanwhile, we found 2.29% of the patients required urgent nutritional support (PG-SGA score ≥ 9). Multivariate analysis showed that age (p = 0.013), BMI (p = 0.001), weight loss (p = 0.001), anemia (p = 0.005), pre-albumin (p = 0.010), albumin (p = 0.002), tumor location (p = 0.001), tumor size (p = 0.002), and NIH classification (p = 0.001) were risk factors for nutritional status. The prognosis was significantly in GIST patients with different PG-SGA score at admission (p < 0.05). Conclusion: This study suggested that malnutrition is common in newly diagnosed GIST patients, and the higher the PG-SGA score, the worse the clinical outcome.

Clinical Relevance and Prognostic Value of Inflammatory Biomarkers: A prospective Study in Terminal Cancer Patients Receiving Palliative Care

CONTEXT

Inflammatory biomarkers have prognostic value in cancer patients, but the feasibility of their use with terminal cancer patients and the related cutoff points are poorly explored.

OBJECTIVES

To describe the percentiles values of inflammatory biomarkers; to identify their cutoff points in relation to death; and to determine the prognostic value of C-reactive protein (CRP), leukocytes, neutrophils, neutrophil/lymphocyte ratio (NLR), CRP/albumin ratio (CAR), and modified Glasgow Prognostic Score for death within 90 days, in terminal cancer patients receiving palliative care.

METHODS

Prospective cohort study that included patients who received palliative care at the Palliative Care Unit of the National Cancer Institute (Brazil) between October 2019 and March 2020. Receiver operating characteristic curves were used to identify the optimal cutoff points of the inflammatory biomarkers for the prediction of death in 90 days. Kaplan-Meier curves and Cox regression were used to verify the prognostic value of these cutoff points and concordance statistic (C-statistic) was used to test their predictive accuracy.

RESULTS

A total 205 patients (mean age: 62.5 years; female: 59%) were included in the study. The optimal cutoff points were CRP ≥6.7mg/L, CAR ≥2.0, leukocytes ≥9300/μL, neutrophils ≥7426/μL and NLR ≥6.0. All biomarkers showed prognostic value and good predictive accuracy when their cutoff points were used, especially CAR, which presented excellent discrimination power (C-statistic: 0.80).

CONCLUSION

The inflammatory biomarkers analyzed are independent predictive factors for death within 90 days in terminal cancer patients. CAR appears to be the most useful parameter for predicting survival in these patients.

Validation of the scored Patient-Generated Subjective Global Assessment Short Form as a prognostic tool for patients with incurable cancer

BACKGROUND

The Patient-Generated Subjective Global Assessment Short Form (PG-SGA SF) is a standardized tool for assessing nutrition risk in patients with cancer. The aim of this study was to propose and validate a cutoff point for the PG-SGA SF related to the prognosis of patients with incurable cancer in exclusive palliative care.

METHODS

This is a prospective cohort study of patients with incurable cancer at the National Cancer Institute in Brazil. A total sample (n = 2,144) was randomly divided into groups: (1) training (n = 1,072), to determine the most accurate PG-SGA SF cutoff, and (2) validation (n = 1,072), to test the predictive accuracy of this cutoff point. The receiver operating characteristic curve was plotted to determine the best cutoff point of the PG-SGA SF related to death. Concordance statistics (C statistic) were used to test the predictive accuracy of the models. Kaplan-Meier curve and the Cox hazard model were used to verify a prognostic value of the cutoff point.

RESULTS

PG-SGA SF score ≥15 was found to be the best cutoff based on 90-day mortality with good accuracy discrimination (C statistic ≥ 0.74). Patients whose PG-SGA SF score was ≥15 had a shorter survival of 32 (interquartile range [IQR], 12-75) vs 83 days (IQR, 31-90) (p-value < .001) and higher risk of death (hazard ratio: 2.20; 95% CI, 1.64-2.95).

CONCLUSIONS

The proposed PG-SGA SF cutoff score is valid and, alongside its usefulness in nutrition triage, could provide prognostic value for patients with incurable cancer.

Body Mass Index Alters the Predictive Value of the Neutrophil-to-Lymphocyte Ratio and Systemic Inflammation Response Index in Laryngeal Squamous Cell Carcinoma Patients

Laryngeal squamous cell carcinoma (LSCC) is a frequent cancer subtype among head and neck cancers. Exacerbated inflammation and nutritional deficit are common features in this type of cancer and can be used as a prognostic marker. This study aimed to investigate the relationship between body mass index (BMI), neutrophil-to-lymphocyte ratio (NLR), and systemic inflammation response index (SIRI) on overall survival (OS) of LSCC patients. In this retrospective cohort study, 168 patients were followed for 5 years. Data on clinical factors, patients' life habits, height, weight, and hematological parameters were collected. BMI, NLR, and SIRI were calculated. Pretreatment NLR≥ 2.02 and SIRI≥ 1160.85 were independent prognostic factors for poor OS. Low BMI did not significantly affect the OS. However, the inflammatory parameters had their predictive capacity altered when stratified by the BMI classification. NLR≥ 2.02 + Low BMI or SIRI≥ 1160.85 + Low BMI increased in 8.6 and 3.8 times the risk of death, respectively. In contrast, stratification by normal/high BMI classification eliminated the predictive capacity of NLR and SIRI. Here, we demonstrated the possible ability of BMI to change the prognostic capacity of inflammatory markers NLR and SIRI in patients with LSCC.Supplemental data for this article is available online at https://doi.org/10.1080/01635581.2021.1952447.

Diagnostic Performance of SGA, PG-SGA and MUST for Malnutrition Assessment in Adult Cancer Patients: A Systematic Literature Review and Hierarchical Bayesian Meta-Analysis

Because cancer-associated malnutrition is a major health complication, timely nutritional screening is of utmost importance. The aim of this study was to conduct a systematic literature review and meta-analysis of three tools in order to identify the method with the best diagnostic performance. PubMed, EMBASE and Cochrane central register of controlled trials were searched for articles published from database inception to January 2021. Studies that assessed the diagnostic accuracy of the SGA, PG-SGA or MUST in adult cancer patients were included. In order to evaluate the quality of each included study, the QUADAS-2 tool was used after which a meta-analysis was conducted using the hierarchical bivariate model. This model accounts for both within and between study variability. 16 studies (18 datasets) were included to evaluate these tools. The overall sensitivity and specificity for SGA was 0.69 and 0.80, 0.95 and 0.81 for PG-SGA, along with 0.83 and 0.83 for MUST respectively. An assessment of the likelihood ratios showed that PG-SGA had the highest LR + and the lowest LR-, it therefore has the best diagnostic performance to confirm malnutrition in adult cancer patients.

Factors Associated With Efficacy and Nivolumab-Related Interstitial Pneumonia in Non-Small Cell Lung Cancer: A Retrospective Survey

BACKGROUND AND OBJECTIVES

Immune-checitors have been established as a novel standard treatment for non-small cell lung cancer (NSCLC). The aim of this study was to identify factors associated with efficacy and nivolumab-related interstitial pneumonia in NSCLC by evaluating clinical data at the initiation of and during treatment.

METHODS

We retrospectively reviewed the medical records of patients who underwent treatment with nivolumab between October 2015 and December 2017. Using pretreatment patient data, we investigated factors associated with overall survival (OS) and the onset of nivolumab-related pneumonitis. We investigated serum biochemistry during treatment to identify the determinants associated with progressive disease (PD) and the onset of nivolumab-related pneumonitis.

RESULTS

A total of 94 patients were included. Eleven patients continued treatment, and 54 patients were diagnosed with progressive disease. Nivolumab-related pneumonitis occurred in 15 patients. A pretreatment Eastern Cooperative Oncology Group Performance Status (ECOG PS) = 0 was linked to significantly longer OS than ECOG PS = 1 (median: 20.1 vs. 6.5 months, respectively; p < 0.001). There was a higher incidence of nivolumab-related pneumonitis in patients with a history of interstitial pneumonia than in those without it (p = 0.008). During treatment, the level of albumin gradually decreased prior to PD and onset of nivolumab-related pneumonitis.

CONCLUSION

These results suggest that the pretreatment ECOG PS is the determining factor that is associated with OS, whereas history of interstitial pneumonia is the factor associated with nivolumab-related pneumonitis. A decrease in albumin during treatment may be associated with both PD and nivolumab-related pneumonitis.

Clinical malnutrition predictive model among gynecologic cancer patients prior to elective operation: A cross-sectional study

BACKGROUND

Malnutrition is common among cancer patients regardless of stage of cancer. Given the strong association between malnutrition with prolonged hospitalization, delayed recovery and even higher post-operative complications among gynaecologic cancer (GC) patients, it is important to understand its predictive factors. The current study aimed to determine malnutrition predictors among GC patients before elective operation.

METHOD

A cross-sectional study was conducted among surgical GC patients who were admitted for elective surgery. Data on socio-demographic characteristics, clinical status (diagnosis, the staging of cancer, comorbidities and family history on cancer), anthropometric measures [ Body Mass Index (BMI), weight changes, the percentage of weight loss past one month, muscle mass, fat mass, fat-free mass and mid-upper arm circumference (MUAC)], biochemical profiles [C-reactive protein, albumin and C-reactive protein (CRP) to albumin ratio (CAR)], handgrip strength, total daily energy and protein intake, and malnutrition status [scored Patient Generated-Subjective Global Assessment (PG-SGA)] were assessed during admission.

RESULTS

Study recruited 124 participants and 57.2% (n = 71) were malnourished. Mean for age, weight changes past one month, handgrip strength, total daily energy and protein intake, PG-SGA score and CAR of participants were 49.9 ± 12.5 years, -4.9 ± 7.2%, 15.6 ± 6.2 kg, 25±7 kcal/kg/day, 1.0 ± 0.3 g/kg/day, 6.5 ± 5.4 and 0.7 ± 1.9, respectively. Multiple linear regression test revealed that the percentage of weight loss past one month, haemoglobin, CRP and handgrip strength were the significant predictors of malnutrition.

CONCLUSION

Malnutrition is common among GC patient even before elective operation. The early malnutrition screening following with proper nutritional intervention is crucial to optimize nutritional status among GC patients before elective operation.

Prognostic value of advanced lung cancer inflammation index in patients with colorectal cancer liver metastases undergoing surgery

INTRODUCTION

Recently, a new inflammatory marker, the advanced lung cancer inflammation index (ALI), was reported as a prognostic marker in patients with several cancers. We aimed to investigate the prognostic value of ALI in patients with colorectal cancer liver metastases (CLM) undergoing surgery.

METHODS

From June 2009 to June 2018, 141 patients underwent a surgery for CLM at Ajou University Hospital, of whom 132 without extrahepatic metastases, systemic inflammatory diseases, or immune system diseases were enrolled in this study. The ALI was calculated using the following formula: ALI = body mass index × serum albumin/neutrophil-to-lymphocyte ratio. The patients were divided into high (n = 32) and low (n = 100) ALI groups according to the preoperative optimal cutoff value of 70.40 that was determined by X-tile software.

RESULTS

Patients with low ALI had a significantly worse overall survival (OS) compared to the high ALI group (p = 0.010). Multivariate analysis showed that ALI and carcinoembryonic antigen (CEA) were independently associated with OS (p = 0.009 and p = 0.042, respectively). Among the patients with CEA >5 ng/mL, the low ALI group had a significantly worse OS compared to the high ALI group (p = 0.013).

CONCLUSION

Preoperative ALI was a prognostic factor in patients with CLM undergoing surgery. In particular, the prognostic impact of ALI was more prominent in the patients with CEA >5 ng/mL.

Preoperative Fasting Abbreviation With Whey Protein Reduces the Occurrence of Postoperative Complications in Patients With Head and Neck Cancer: A Randomized Clinical Trial

BACKGROUND

Surgery has become the treatment of choice for head and neck cancer (HNC) in most cases. Preoperative fasting abbreviation and nutrition screening have been suggested to reduce the occurrence of postoperative complications. This study aimed to evaluate the addition of whey protein in the preoperative fasting abbreviation and to analyze the association of nutrition status on postoperative complications in patients with HNC.

METHODS

A randomized, single-blind clinical trial was performed. Patients recruited from March to November 2018 at a national cancer reference center in Brazil were divided into 2 groups: intervention group (clear fluids with carbohydrate plus whey protein [CHO-P]) and control group (clear fluids with carbohydrate only [CHO]). All patients were evaluated by the Patient-Generated Subjective Global Assessment (PG-SGA) and body mass index. Logistic regression analyses were performed to assess associations between the studied variables, generating odds ratios (ORs) and 95% confidence intervals (CIs).

RESULTS

A total of 49 patients met the eligibility criteria and enrolled in the study. A PG-SGA score of 4-8, indicating moderate malnutrition (OR, 10.91; 95% CI, 1.05-112.91), was an independent factor that increased the risk of postoperative complication, whereas the CHO-P group (OR, 0.04; 95% CI, 0.01-0.26) was found to be an independent factor in reducing such risk.

CONCLUSION

The addition of whey protein to clear fluids (CHO-P group) was associated with a reduced risk of postoperative complications compared with the CHO group. Furthermore, moderate malnourishment was associated with an increased risk of postoperative complications for patients with HNC.

Association of malnutrition with postoperative complication risk after curative surgery for oral cancer: Observational study

Malnutrition is common among patients who have oral cavity squamous cell carcinoma (OSCC), but its effect on the incidence of postoperative complications remains uncertain. Validated nutrition and complication assessment tools were used to evaluate the effects of nutrition on the likelihood of postoperative complications after curative surgery for OSCC.A retrospective study that spanned January 2014 to December 2018 enrolled 70 patients who received curative surgery for OSCC. Nutritional status before surgery was evaluated with the scored Patient-Generated Subjective Global Assessment (PG-SGA), and patients were classified as either well-nourished (rating A) or malnourished (ratings B and C). Complications 30 days after the operation were graded using Clavien-Dindo classification. The perioperative clinicopathological characteristics of the groups were compared, and risk factors for postoperative complications were identified through logistic regression.A total of 44 (62.8%) patients formed the malnourished group, and they tended to be older (P = .03), weigh less (P = .001), have lower Body Mass Index (P = .003), higher PG-SGA scores (P < .001), higher neutrophil-to-lymphocyte ratio (P = .034), more postoperative complications (P < .001), and longer hospital stays (P = .021). Major complications (Clavien-Dindo classification ≥ IIIa) were experienced by 18.5% (n = 13) of patients and were more common in the malnourished group (P = .007). Multivariate logistic regression demonstrated that PG-SGA score ≥4 was an independent risk factor for postoperative complications (hazard ratio = 4.929, P = .008).Malnutrition defined using the PG-SGA is an independent risk factor for postoperative complications of curative surgery in patients with OSCC. More prospective studies are warranted to confirm our findings.

Evaluation of pro-inflammatory cytokines in frail Tunisian older adults

The present study was undertaken to evaluate serum levels of pro-inflammatory cytokines in Tunisian older adults and to examine the relationships between inflammatory marker levels, geriatric, and biochemical parameters. A cross-sectional study was conducted in a population of Tunisian older adults (N = 141, aged 65 and over). Patients were recruited from the Department of Internal Medicine, Fattouma Bourguiba University Hospital (Monastir, Tunisia) and from a nursing home (Sousse, Tunisia). Comprehensive geriatric assessment, history taking and examination including functional and nutritional assessment were done for each participant. Enzyme-linked immunosorbent assay (ELISA) test was used to measure serum cytokine (TNF-α, IL-8, IL-6) levels. The modified Short Emergency Geriatric Assessment score (SEGAm) were used to classify patients as 51 very-frail, 40 frail, and 50 non-frail. The age of the participants (80 men, 61 women) ranged from 65 to 97 years. Serum levels of TNF-α, IL-8 and C-reactive protein (CRP) were significantly higher in very-frail participants compared to frail and non-frail ones. However, no significant differences in IL-6 levels were detected among frailty groups. After adjustment for age, CRP and IL-8 levels remained significantly associated with frailty. Analysis of the receiver operating characteristic (ROC) curve corresponding to IL-8 showed an area under the curve of 0.7 (p = 0.003; 95% CI [0.58-0.81]) and a predictive threshold of 5.27 pg/ml. Positive correlations were found between frailty score, IL-6, and IL-8 levels. In addition, a significant positive correlation was observed between IL-8 levels and Timed Up and Go test results. However, a negative correlation was observed between Mini Nutritional Assessment Short-Form score, IL-6 and CRP levels, as well as between Activities of Daily Living score and serum levels of TNF-α, IL-6, and CRP. In conclusion, the key findings of this study collectively support a role of pro-inflammatory cytokines, TNF-α, CRP, and especially IL-8 in the development of frailty in older adults.

Nutrition and metabolism status alteration in advanced hepatocellular carcinoma patients treated with anti-PD-1 immunotherapy

PURPOSE

The aim of this study was to evaluate the nutrition and metabolism status alteration during immunotherapy in advanced hepatocellular carcinoma (HCC) patients.

METHODS

Patients with advanced HCC who participated in the clinical trials of single-agent anti-PD-1 immunotherapy or sorafenib were retrospectively included. We analyzed self-comparison of the nutritional and metabolic indices of patients in the anti-PD-1 and sorafenib treatment group. We conducted mutual-comparison of the mentioned indices between the disease progression group and disease control group among anti-PD-1 treatment patients. We further analyzed those indices with statistical differences by partial correlation and survival analysis.

RESULTS

Both self-comparison before and after treatment in the anti-PD-1 group and mutual-comparison of disease progression and the control group showed significant differences in multiple indices, but we did not observe significant differences in the sorafenib group. Strikingly, albumin (ALB)/prognostic nutritional index (PNI, calculated by serum albumin and lymphocyte count) decreased distinctly in the immunotherapy disease progression group patients. However, changes in ALB/PNI were not significant in disease progression patients from the sorafenib group or in the disease control patients with immunotherapy. Partial correlation analysis suggested that ALB and PNI were positively correlated with the efficacy of immunotherapy. Furthermore, survival analysis showed that the median progression-free survival and median overall survival of patients in the ALB/PNI decreased group were significantly shorter than those of patients from the ALB/PNI increased group.

CONCLUSION

Anti-PD-1 immunotherapy might alter the nutritional and metabolic status in advanced HCC patients. We also should pay attention to the nutritional and metabolic status of patients when drug resistance is detected.

Neutrophil-to-lymphocyte ratio can predict outcome in extensive-stage small cell lung cancer

Background

The neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and lymphocyte-to-monocyte ratio (LMR) were analyzed in various carcinomas and their potential prognostic significance was determined. The objective of present study was to determine the correlation between these parameters and the survival of patients with small cell lung cancer (SCLC), since very few studies have been published on this type of carcinoma.

Patients and methods

One hundred and forty patients diagnosed with SCLC at University Hospital Center Zagreb, between 2012 and 2016 were retrospectively analyzed. Extensive-stage disease (ED) was verified in 80 patients and limited-stage disease (LD) in 60 patients. We analyzed the potential prognostic significance of various laboratory parameters, including NLR, PLR, and LMR, measured before the start of treatment.

Results

Disease extension, response to therapy, chest irradiation and prophylactic cranial irradiation (PCI), as well as hemoglobin, monocyte count, C-reactive protein (CRP), and lactate dehydrogenase (LDH) showed a prognostic significance in all patients. When we analyzed the patients separately, depending on the disease extension, we found that only skin metastases as well as LDH and NLR values, regardless of the cut-off value, had a prognostic significance in ED. Meanwhile, the ECOG performance status, chest irradiation, PCI, and hemoglobin and creatinine values had a prognostic significance in LD.

Conclusions

NLR calculated before the start of the treatment had a prognostic significance for ED, while PLR and LMR had no prognostic significance in any of the analyzed groups of patients.

Determining the prevalence and severity of cancer cachexia in advanced non-small cell lung cancer and its relationship with chemotherapy outcomes

PURPOSE

Cancer cachexia (CC) is a syndrome characterised by an ongoing loss of skeletal muscle mass associated with reduced tolerance to treatment. This study explored the prevalence and severity of CC in advanced non-small cell lung cancer (NSCLC) patients and determined its relationship with chemotherapy outcomes.

METHODS

CC was classified into a four-stage model: no cachexia, pre-cachexia (PC), cachexia and refractory cachexia (RC) with categorisation determined from biochemical and body composition and performance assessment. Associations between the stage of cachexia and chemotherapy outcomes including radiological response, the number of chemotherapy cycles completed and the number of cycles delayed or dose reduced were explored.

RESULTS

Twenty-four patients were included with 4 (18%) classified as having no cachexia, 4 (18%) PC, 3 (14%) cachexia (13.6%), and 11 (50%) RC. No association was observed between the stage of cachexia and the radiological response to chemotherapy number of cycles delayed or the number of cycle's dose reduced; however, there was an association with the number of cycles completed (p = 0.030). An association between C-reactive protein (CRP) and the number of chemotherapy cycles completed (p = 0.044) and the number of dose reductions (p = 0.044) was also identified.

CONCLUSIONS

Limited conclusions can be drawn given the small sample size. However, the majority of patients presented with some degree of cachexia at diagnosis. A relationship was identified between the increasing severity of cachexia and a lower number of chemotherapy cycles completed, as well as between CRP and the number of chemotherapy cycles completed and the number of dose reductions required, and therefore warrants further exploration in larger studies.

Prognostic Markers of Overall Survival in Cancer Patients Attending a Cachexia Support Service: An Evaluation of Clinically Assessed Physical Function, Malnutrition and Inflammatory Status

BACKGROUND

Cancer cachexia is a muscle-wasting syndrome that results in physical function impairments and decreased survival. While body weight and muscle mass loss predict survival, the prognostic significance of physical function in this population is unclear. Thus, we evaluated the association between physical function, and other routine measures, and overall survival (OS) in cancer patients attending a cachexia support service.

METHODS

Physical function was clinically-assessed using the 30 s sit-to-stand test and handgrip strength. Six-month weight loss, the Patient-Generated Subjective Global Assessment (PG-SGA) total score, C-reactive protein (CRP), albumin, and quality of life were also evaluated.

RESULTS

Records from 203 patients (age: 68.6 ± 11.6 years) were included. Handgrip strength did not predict OS. Sit-to-stand repetitions predicted OS in the single variable, but not the multivariable analysis. Multivariable results suggested higher PG-SGA total scores (HR: 1.04, 95% CI: 1.01-1.07), six-month weight loss (HR: 1.02, 95% CI: 1.004-1.04), and elevated CRP (HR: 1.004, 95% CI: 1.0004-1.01) predicted shorter OS. Higher albumin predicted longer OS (HR: 0.93, 95% CI: 0.90-0.97).

CONCLUSION

Six-month weight loss, the PG-SGA total score, CRP, and albumin independently predicted survival, while physical function did not. Functional impairments remain a hallmark of cancer cachexia and the benefit of their routine assessment warrants further exploration, especially in relation to patient quality of life.

Nutritional Deficits In Children With Cancer: A Situation-Specific Theory

PURPOSE

To construct a situation-specific theory (SST) to represent nutritional deficits for assessing children with cancer.

DATA SOURCES

Literature review.

DATA SYNTHESIS

The SST included the definition of key concepts, a pictorial scheme, propositions, causal relationships, and evidence for nursing practice.

CONCLUSIONS

It was possible to characterize the elements as antecedent and consequent clinical factors to allow for an understanding of the existing relationships between them and their temporality. These elements differed considerably from those included in NANDA International.

IMPLICATIONS FOR NURSING PRACTICE

This study provides additional information so that nurses in clinical practice can infer the presence of nutritional deficits in children with cancer early, given the risk already inherent in the diagnosis of cancer and treatment.

The prevalence of cancer associated systemic inflammation: Implications of prognostic studies using the Glasgow Prognostic Score

The prognostic importance of SIR in patients with cancer is widely recognised. More recently it has become clear that the systemic inflammatory response is an important etiologic factor in the development of cancer cachexia. Two recent meta-analysis carried out in 2017 and 2018 were interrogated and the number of patients with specific cancer types were identified. The percentage of patients with operable cancer (n>28,000) who were systemically inflamed varied from 21% to 38%. The percentage of patients with inoperable cancer (n>12,000) who were systemically inflamed varied from 29% to 79%. Overall, the percentage of patients (n>40,000) who were systemically inflamed varied from 28% to 63% according to tumour type. The most commonly studied cancer was colorectal cancer (n∼10,000 patients) and 40% were systemically inflamed.

The prognostic value of the prognostic nutritional index in patients with metastatic colorectal cancer

OBJECTIVE

The prognostic nutritional index (PNI) has been shown to be prognostic value for many types of cancer of the gastrointestinal system. However, there are limited data on its value for metastatic colorectal cancer (mCRC). This study aimed to evaluate the prognostic value of PNI in newly diagnosed mCRC patients.

METHODS

The data of 468 patients who had been admitted to our center upon being diagnosed with mCRC between January 2010 and December 2017 were reviewed retrospectively, whereby satisfying the inclusion criteria were included in the study. Receiver operating characteristic (ROC) analysis was used for PNI's optimum cut-off value for overall survival (OS). The Cox regression model was used in the single-variable analysis in order to test whether or not variables with prognostic properties were independent prognostic factors.

FINDINGS

A total of 308 patients were included in the study. Sixty-two percent (n = 192) of the patients were males, and the median age was 57.5 years (range: 25-83). Forty-five percent (n = 137) of the patients had KRAS mutation. Tumors localized in the colon accounted for 63% (n = 193) of the patients. The liver was the most common region of metastasis at 69%. According to the ROC curve, the optimal cut-off value for PNI was 46 (sensitivity 74%, specificity 47%, AUC 0.615, 95% confidence interval [CI]: 0.54-0.68, P = .002). One hundred and eighty-two patients (59%) fell into the PNI-High (> 46) group, while 126 patients (41%) fell into the PNI-Low (≤ 46) group. The rectum localization was higher, whereas the neutrophil-lymphocyte ratio and platelet-lymphocyte ratio were lower in the PNI-High group. There was no difference in terms of other patient characteristics. The median OS was significantly longer in the PNI-High group compared to the PNI-Low group (28.4 vs 19.1 months, P < .001). The Cox regression analysis showed that a high PNI was an independent positive prognostic factor (hazard ratio: 0.61, 95% CI: 0.42-0.87, P = .007).

DISCUSSION

We found PNI to be an independent prognostic factor in mCRC. We think that PNI, which can be calculated by a simple formula, may provide clinicians important clues in order to make desicion for individual treatment.

P-STAT3 and IL-17 in tumor tissues enhances the prognostic value of CEA and CA125 in patients with lung adenocarcinoma

AIM

The present study aimed to examine the capability of p- signal transducer and activator of transcription (STAT)3 and interleukin-17 (IL-17), along with two known tumor markers carcinoembryonic antigen (CEA) and carbohydrate antigen 125 (CA125), for disease prognosis. Moreover, the associations among biomarkers and clinicopathological parameters were evaluated to uncover the potential mechanisms responsible for their correlations with lung adenocarcinoma (LAD) prognosis.

METHODS

Five LAD-related parameters were used in the study: CEA, CA125, STAT3, p-STAT3, and IL-17. Spearman and chi-square correlation tests were used to explore the relationships between some clinicopathological variables and parameter expression levels and the associations among these five parameters.

RESULTS

The disease-specific survival decreased with the positive expression of CEA, CA125, p-STAT3, and IL-17, with no significant difference in the expression level of STAT3. Combinations of p-STAT3 and IL-17, CEA and p-STAT3, CEA and IL-17, CA125 and p-STAT3, and CA125 and IL-17 had higher predictive values in LAD prognosis. The correlation analyses indicated the synergic activities of STAT3, p-STAT3, and IL-17 and the coordinated expression of CEA, CA125, p-STAT3, and IL-17. The tumor-node-metastasis (TNM) stage significantly correlated with the levels of CA125 and p-STAT3.

CONCLUSIONS

Elevated levels of CEA, CA125, p-STAT3, and IL-17 alone and/or combinations of p-STAT3 and IL-17, CEA and p-STAT3, CEA and IL-17, CA125 and p-STAT3, and CA125 and IL-17 were recommended as the prognostic predictors of unfavorable clinical outcomes in patients with postoperative LAD. Also, p-STAT3 and IL-17 combined with CA125 and CEA helped in predicting the overall survival of patients with LAD and informing the TNM stage.

Effect of whole-course nutrition management on patients with esophageal cancer undergoing concurrent chemoradiotherapy: A randomized control trial

OBJECTIVES

Malnutrition is the most common complication of patients with esophageal cancer and can lead to poor prognosis and death. Good nutritional status has been shown to help improve patient outcomes and reduce complications. In the absence of specific evidence on the effect of nutrition in patients with esophageal cancer, the purpose of this study was to investigate the effect of whole-course nutrition management on the prognosis and complications of chemoradiotherapy in patients with esophageal cancer through a randomized controlled trial.

METHODS

A total of 96 patients with esophageal cancer treated with concurrent chemoradiation were randomized to an intervention group (treated with whole-course nutrition management from the Nutrition Support Team) and a control group (treated with the general nutritional method) for approximately 6 wk. Dietary surveys and body measurements were conducted at baseline and every day thereafter. Patient-generated Subjective Global Assessment score, blood index, quality of life, and psychological condition were assessed at baseline and every week before discharge. Complications (e.g., radiation esophagitis, myelosuppression, and skin symptoms), completion rates of therapy, short-term efficacy evaluation, as well as clinical outcomes were measured.

RESULTS

A total of 85 patients completed the study (intervention group = 45; control group = 40). There were significant differences in the changes of serum albumin and total protein between the two groups throughout the trial (P < 0.05). Complications (e.g., radioactive esophagitis, skin symptom of complications) and quality of life were statistically different before and after the intervention (P < 0.05). The difference in the change of other indicators was not statistically significant.

CONCLUSIONS

Whole-course nutrition management can improve the nutritional status of patients with esophageal cancer treated with concurrent chemoradiotherapy, reduce the severity of radiation esophagitis and radiation skin reactions, improve the quality of life, and relieve depressive symptoms.

Sarcopenia supersedes subjective global assessment as a predictor of survival in colorectal cancer

BACKGROUND

Sarcopenia, the presence of skeletal muscle mass depletion, can be objectively quantified, whereas subjective global assessment (SGA) is a widely utilized subjective instrument to assess nutritional status. Both the presence of sarcopenia and SGA-assessed malnutrition, in isolation, have been shown to be associated with worse overall survival in a wide range of cancers. However, there is no research evaluating the independent prognostic significance of both the presence of sarcopenia and malnutrition as part of the same analysis. We investigated the impact of sarcopenia on overall survival in colorectal cancer specifically controlling for malnutrition.

METHODS

We examined a consecutive case series of 112 patients with colorectal cancer first seen at our institution between August 2012 and October 2017. Using computed tomography (CT) imaging, the cross-sectional area of muscles at the L3 vertebral level was measured and then divided by height squared to calculate skeletal muscle index (SMI). Sarcopenia was defined as SMI ≤38.5 cm2/m2 for women and ≤52.4 cm2/m2 for men. SGA assessments were completed within 2 weeks of CT imaging. The association of sarcopenia and malnutrition with overall survival was assessed using univariate and multivariate Cox regression analysis.

RESULTS

Median age at presentation was 53.3 years. Sixty-six (58.9%) patients had metastatic disease at diagnosis. Using SMI, 46 (41.1%) patients were sarcopenic, while 66 (58.9%) were non-sarcopenic. Using SGA, 69 (61.6%) patients were assessed as well-nourished, while 43 (38.4%) were malnourished. Of 69 patients classified as well-nourished by SGA, 22 (31.9%) were sarcopenic. Similarly, of 43 patients categorized as malnourished by SGA, 19 (44.2%) were non-sarcopenic. On multivariate analysis, after adjusting for age, gender, tumor stage, BMI, treatment history and SGA, patients with sarcopenia had 3 times greater risk of mortality compared to those without sarcopenia (p = 0.001). The median survival of patients with both sarcopenia and malnutrition (n = 24) was 14.6 months (95% CI: 10.5 to 18.6) compared to the median survival of 25.9 months (95% CI: 7.8 to 44.0) in patients who were either sarcopenic or malnourished but not both (n = 41; p = 0.001). The median survival of patients who were non-sarcopenic and well nourished (n = 48; p = 0.001) was 38.6 months (95% CI: 25.6 to 51.6).

CONCLUSIONS

The exploratory study suggests that presence of sarcopenia supersedes the presence of malnutrition as a predictor of survival in colorectal cancer. Co-existence of sarcopenia and malnutrition is associated with worse survival in colorectal cancer compared to just one of those conditions being present. Prospective studies with large sample sizes are needed to confirm these findings.

Contribution of pancreatic enzyme replacement therapy to survival and quality of life in patients with pancreatic exocrine insufficiency

The objective of this study was to analyze the current evidence for the use of pancreatic enzyme replacement therapy (PERT) in affecting survival and quality of life in patients with pancreatic exocrine insufficiency (PEI). Systematic searches of the literature were performed using the PubMed database. Articles were selected for inclusion if they reported findings from trials assessing the effects of PERT on quality of life, survival, malabsorption, growth parameters (such as height, body weight and body mass index), or gastrointestinal symptoms (such as abdominal pain, stool consistency and flatulence). PERT improved PEI-related malabsorption and weight maintenance in patients with cystic fibrosis, chronic pancreatitis, pancreatic cancer, and post-surgical states. In patients with chronic pancreatitis, PERT improved PEI-related symptoms and quality of life measures. Several small retrospective studies have also suggested that PERT may have a positive impact on survival, but long-term studies assessing this effect were not identified. PERT is effective for treating malnutrition and supporting weight maintenance, and it is associated with improved quality of life and possibly with enhanced survival in patients with PEI. However, there is evidence that not all patients with PEI receive adequate PERT. Future work should aim to assess the long-term effects of PERT on the survival of patients with PEI.

Malnutrition in patients who underwent surgery for spinal metastases

Background

Malnutrition is common among cancer patients and has been associated with increased morbidity and mortality. The primary objective of this study was to evaluate the nutritional status of patients who underwent surgical treatment for spinal metastases. In addition, the association between nutritional status and length of stay, health related quality of life (HRQOL), the occurrence of adverse events and survival was investigated.

Methods

A single center prospective observational cohort study including patients with spinal metastases who underwent surgical treatment was performed. Demographic, diagnostic, treatment, and HRQOL (SOSGOQ2.0 and EQ-5D-3L) data were prospectively collected at baseline and 12 weeks post-treatment. Nutritional status was evaluated with the Patient-Generated Subjective Global Assessment (PG-SGA).

Results

A total of 39 patients were included. Malnutrition as determined by the PG-SGA was present in 36 (92%) of the patients, of whom 32 (82%) were moderately malnourished and 4 (10%) were severely malnourished. Malnourishment was associated with lower baseline SOSGOQ2.0 total scores, SOSGOQ2.0 physical function, mental health and social functioning scores, EQ-5D total scores and EQ-5D mobility scores. No association between malnutrition and survival could be determined.

Conclusions

The prevalence of malnutrition among surgically treated patients with spinal metastases is high. Malnutrition demonstrated to be associated with lower baseline HRQOL scores. Future larger studies are needed to further investigate the prognostic significance of malnutrition.

Nutritional status and related factors of patients with advanced lung cancer in northern China: a retrospective study

Background

Mortality of lung cancer in northern China has been increasing at an alarming speed. The consequences of malnutrition may include an increased risk of many complications. However, the nutritional status in advanced lung cancer patients is still unknown. So the aims of this research are to report on the prevalence of malnutrition in our population, the proportion of participants requiring nutrition interventions, and the relationship between nutritional status at diagnosis and overall survival (OS).

Patients and methods

We evaluated 495 patients with advanced lung cancer (stage IIIB and IV). Nutritional status was estimated by the Patient-Generated Subjective Global Assessment (PG-SGA). This study investigated the clinical significance of PG-SGA scores at admission by following OS. Kaplan–Meier survival analysis and the log-rank test were used to calculate OS. Univariate and multivariate analyses of the OS were performed using Cox analysis.

Results

Our results showed that 88.9% of the patients required nutrition intervention and 25.1% of the patients required improved nutrition-related symptom management and/or urgent nutritional support (PG-SGA score ≥9). Factors related to malnutrition were age, sex, pathology, TNM stage, smoking condition, anemia, body mass index, pre-albumin, and albumin. The research outcomes indicated that PG-SGA score at admission was significantly associated with OS, which was still maintained when stratified by age and sex.

Conclusion

Malnutrition was prevalent in patients with advanced lung cancer. Poor nutritional status was associated with worse clinical outcomes.

A novel prognostic model for tongue squamous cell carcinoma based on the characteristics of tumour and its microenvironment: iBD score

AIMS

Tumour budding and invasive depth can predict survival of patients with tongue squamous cell carcinoma (TSCC), while the prognostic value of tumour microenvironment (TME) remains unknown. Here, both characteristics of the tumour and its microenvironment were examined and a novel prognostic model has been proposed.

METHODS AND RESULTS

A total of 246 patients with TSCC were included. Using H&E-stained sections, pathological parameters of tumour and the TME were assessed. Inflammatory response (i), tumour budding (B) and invasive depth (D) were combined as iBD score. The association between these variables and the patient survival was determined. Both tumour budding and inflammatory status were independent variables for predicting overall survival (OS) and disease-free survival (DFS) of TSCC patients. Invasive depth was correlated with differentiation, T classification, lymph node metastasis, clinical stage and recurrence (P < 0.05). The novel iBD model was strongly correlated with T classification, lymph node metastasis, clinical stage and recurrence, and showed clear distinction of scores 0, 1 and 2. High iBD score had a strong association with reduced OS and DFS (P < 0.01).

CONCLUSIONS

The iBD scoring model is strongly associated with lymph node metastasis and recurrence in TSCC and could be a promising survival predictor for TSCC patients.

Hydroalcoholic extract of Brazilian green propolis modulates inflammatory process in mice submitted to a low protein diet

The occurrence of inflammation and protein malnutrition is an aggravating risk factor for morbidity and mortality in the clinical setting. The green propolis, a natural product made by Apis mellifera bees from Baccharis dracunculifolia resin, has therapeutic potential to modulate chronic inflammation. However, its effect on inflammation in an impaired nutritional status is not known. The aim of this study was to characterize the effects of the administration of the hydroalcoholic extract of the green propolis in the chronic inflammatory process of mice submitted to a low-protein diet. For this, we used the subcutaneous implantation of sponge disks as an inflammatory model and the animals were distributed in the following groups: standard protein diet (12% protein content), control treatment; standard protein diet, propolis treatment; low-protein diet (3% protein content), control treatment; low-protein diet, propolis treatment. Propolis was given daily at a dose of 500 mg/kg (p.o.) during a period of 7 or 15 days. Our main findings show that animals fed with standard protein diet and treated with propolis had low levels of red blood cells, hemoglobin, and hematocrit, with the subsequent reestablishment of these levels, in addition to monocyte count elevation and higher TNF levels after one week of treatment. In the low-protein diet group, the propolis treatment provided a significant recovery in weight and maintenance of total serum protein levels at the end of two weeks of treatment. Histological analysis showed propolis reduced the inflammatory infiltrate in the sponges of both standard and low-protein diet groups. In addition, the propolis extract presented antiangiogenic effect in both groups. Therefore, our data suggests that the hydroalcoholic extract of the green propolis promotes weight recovery and avoid the reduction of protein levels, in addition to inhibit inflammation and angiogenesis in animals fed with a low-protein diet.

Early Enteral Nutrition Adequacy Mitigates the Neutrophil-Lymphocyte Ratio Improving Clinical Outcomes in Critically Ill Surgical Patients

BACKGROUND

Neutrophil-lymphocyte ratio (NLR) is a measure of host inflammatory response; a higher NLR is associated with worse clinical outcomes. Enteral nutrition (EN) may mitigate inflammation through interaction with gut-associated lymphoid tissue. We hypothesized that early EN adequacy in critically ill surgical patients is associated with lower NLR and better clinical outcomes.

METHODS

In this retrospective study, we analyzed data from adult surgical intensive care unit (ICU) patients receiving EN. NLR at baseline ICU admission (NLR-B), NLR after 3-5 days of EN (F-NLR), nutrition adequacy, caloric deficit (CD), protein deficit (PD), hospital length of stay (LOS), ICU LOS, 28-day ventilator-free days (28-VFD), and in-hospital mortality were collected. Tertiles groups were created for NLR, F-NLR, CD, and PD; the highest (H) and lowest (L) tertiles were compared. Regression analyses were performed to control for effect of age, gender, APACHE II, and NLR.

RESULTS

Subjects in the L-CD group had lower median F-NLR (7 [range, 5-11] vs 10 [7-22], P = 0.005) and shorter ICU LOS (9 [6-16]) vs 16 [9-32] days; P = 0.006). The L-NLR group had shorter hospital LOS (18 [10-31] vs 22 [15-38] days, P = 0.023), greater 28-VFD (23 [18-25] vs 19 [11-22] days, P = 0.005), and lower in-hospital mortality (13% vs 41%, P = 0.002).

CONCLUSION

In critically ill surgical patients, early enteral caloric adequacy is associated with less inflammation and improved clinical outcomes.

The neutrophil-to-lymphocyte ratio prechemotherapy and postchemotherapy as a prognostic marker in metastatic gastric cancer

BACKGROUND/AIMS

Markers of inflammation have been associated with outcomes in various cancers. The purpose of this study was to evaluate whether systemic inf lammatory markers and their f luctuations can predict survival and chemotherapy response in patients with metastatic gastric cancer (mGC).

METHODS

We retrospectively reviewed the records of 502 patients who received first-line palliative chemotherapy for mGC between 2007 and 2013. The neutrophil-to-lymphocyte ratio (NLR) and modified Glasgow prognostic score (mGPS) were assessed before and after chemotherapy to evaluate their association with survival. The NLR values were categorized into two groups based on a cut-off value of 3; mGPS values were classified as high versus low.

RESULTS

High prechemotherapy NLR was significantly associated with poor overall survival on univariate analysis (p = 0.002). On multivariate analysis, high prechemotherapy NLR (hazard ratio, 1.43; p < 0.001) was an independent prognostic factor for poor overall survival. However, the prechemotherapy mGPS was not significantly associated with survival. Continuously high NLR or a shift to high NLR postchemotherapy was associated with poor chemotherapy response as well as survival, while NLR reduction was associated with a good response (linear by linear association, p < 0.001) and a favorable prognosis.

CONCLUSION

Prechemotherapy NLR can be used as a prognostic factor in mGC, while the postchemotherapy NLR value may predict the chemotherapeutic response and prognosis. In contrast, mGPS has limited prognostic utility in mGC.
