Ji H, Liu B, Jin P, Li Y, Cui L, Jin S, Wu J, Shan Y, Zhang Z, Ming J, Zhang L, Du C. Creatinine-to-cystatin C ratio and body composition predict response to PD-1 inhibitors-based combination treatment in metastatic gastric cancer. Front Immunol 2024; 15:1364728. [PMID: 38665913 PMCID: PMC11043572 DOI: 10.3389/fimmu.2024.1364728] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2024] [Accepted: 04/01/2024] [Indexed: 04/28/2024] Open
Abstract
Background Creatinine-to-cystatin C ratio (CCR) and body composition (BC) parameters have emerged as significant prognostic factors in cancer patients. However, the potential effects of CCR in gastric cancer (GC) remains to be elucidated. This multi-center retrospective study explored the predictive and prognostic value of CCR and BC-parameters in patients with metastatic GC receiving PD-1 inhibitors-based combination therapy. Methods One hundred and thirteen GC patients undergoing PD-1 inhibitors-based combination therapy were enrolled at three academic medical centers from January 2021 to July 2023. A deep-learning platform based on U-Net was developed to automatically segment skeletal muscle index (SMI), subcutaneous adipose tissue index (SATI) and visceral adipose tissue index (VATI). Patients were divided into two groups based on the median of CCR or the upper tertile of BC-parameters. Logistic and Cox regression analysis were used to determine the effect of CCR and BC-parameters in predicting response rates and survival rates. Results The CCR was positively correlated with SMI (r=0.43; P<0.001), but not with SATI or VATI (P>0.05). Multivariable logistic analysis identified that both low CCR (OR=0.423, P=0.066 for ORR; OR=0.026, P=0.005 for DCR) and low SATI (OR=0.270, P=0.020 for ORR; OR=0.149, P=0.056 for DCR) were independently associated with worse objective response rate (ORR) and disease control rate (DCR). Patients with low CCR or low SATI had significantly lower 8-month progression-free survival (PFS) rate and 16-month overall survival (OS) rate than those with high CCR (PFS rate, 37.6% vs. 55.1%, P=0.011; OS rate, 19.4% vs. 44.9%, P=0.002) or those with high SATI (PFS rate, 37.2% vs. 53.8%, P=0.035; OS rate, 8.0% vs. 36.0%, P<0.001). Multivariate Cox analysis showed that low CCR (HR=2.395, 95% CI: 1.234-4.648, P=0.010 for PFS rate; HR=2.528, 95% CI: 1.317-4.854, P=0.005 for OS rate) and low SATI (HR=2.188, 95% CI: 1.050-4.560, P=0.037 for PFS rate; HR=2.818, 95% CI: 1.381-5.752, P=0.004 for OS rate) were both independent prognostic factors of poor 8-month PFS rate and 16-month OS rate. A nomogram based on CCR and BC-parameters showed a good performance in predicting the 12- and 16-month OS, with a concordance index of 0.756 (95% CI, 0.722-0.789). Conclusions Low pre-treatment CCR and SATI were independently associated with lower response rates and worse survival in patients with metastatic GC receiving PD-1 inhibitors-based combination therapy.

[PMID: 37513603 PMCID: PMC10386384 DOI: 10.3390/nu15143182] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2023] [Revised: 07/16/2023] [Accepted: 07/17/2023] [Indexed: 07/30/2023] Open
Abstract
This study aimed to clarify the factors associated with death due to other diseases after a gastrectomy for gastric cancer. This retrospective cohort study included consecutive patients who had undergone gastrectomy between April 2008 and June 2018 for primary stage II-III gastric cancer. The primary outcome was other-cause survival. To identify prognostic factors for other-cause survival for univariate analysis, we used a Cox proportional hazard regression model. A total of 512 patients met the inclusion criteria. The average age was 67.93 years, and the average body mass index was 22.75 kg/m2, with 84 (16.4%) being moderately malnourished and 88 (17.2%) being severely malnourished, as defined by the Global Leadership Initiative on Malnutrition (GLIM) criteria. The other-cause survival for the malnourished group was significantly worse than that for the normal group (p < 0.001). The prognosis was worse when the severity of malnutrition was worse (p < 0.001). Multivariate analysis showed that severe malnutrition was significantly independent of prognostic factors for other-cause survival (hazard ratio: 3.310; 95% confidence interval: 1.426-7.682; p = 0.005). Undernutrition, as defined by the GLIM criteria, is useful for the preoperative prediction of death due to other diseases after gastrectomy in patients with advanced gastric cancer.

[PMID: 36368263 DOI: 10.1016/j.nut.2022.111866] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2022] [Revised: 09/27/2022] [Accepted: 10/02/2022] [Indexed: 11/09/2022]
Abstract
OBJECTIVES Gastric cancer is among the most common and lethal cancers worldwide. Recently, studies have reported that myosteatosis is a prognosticator for adverse survival outcomes in patients with gastric cancer, but with inconsistent conclusions. Therefore, this meta-analysis aimed to systematically quantify the predictive power of myosteatosis for overall survival in the gastric cancer setting. METHODS A systematic literature earch was conducted based on three databases (PubMed/Medline, EMBASE, and Web of Science) from inception until November 30, 2021. This meta-analysis pooled the hazard ratios and their 95% confidence intervals of mortality risk in patients with gastric cancer with myosteatosis versus nonmyosteatosis using a fixed-effects model. RESULTS Twelve studies of 5904 patients were included. Myosteatosis was associated with higher mortality risk (hazard ratio: 1.46; 95% confidence interval, 1.32-1.61; P < 0.001; I2 = 23.8%) in the gastric cancer setting. The results of the subgroup analysis revealed that patients with myosteatosis undergoing surgery had significantly shortened overall survival. Overall, the results of this meta-analysis are robust to sensitivity and trial sequential analyses. CONCLUSIONS Myosteatosis was identified as a strong predictor of reduced overall survival in the gastric cancer population.

Effect of malnutrition as defined by the Global Leadership Initiative on Malnutrition criteria on compliance of adjuvant chemotherapy and relapse-free survival for advanced gastric cancer. Nutrition 2022; 109:111958. [PMID: 36716614 DOI: 10.1016/j.nut.2022.111958] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2022] [Revised: 12/07/2022] [Accepted: 12/23/2022] [Indexed: 12/28/2022]
Abstract
OBJECTIVES The aim of the present study was to clarify the effect of malnutrition as defined by the Global Leadership Initiative on Malnutrition (GLIM) criteria on compliance with postoperative adjuvant chemotherapy and relapse-free survival (RFS) in patients with gastric cancer. METHODS This single-center, retrospective cohort study included 281 consecutive patients with gastric cancer who underwent radical gastrectomy for pathologic stages II and III and received postoperative S-1 adjuvant chemotherapy between April 2008 and June 2018. Treatment failure was defined as discontinuation of adjuvant chemotherapy ≤1 y. Nutritional assessment was preoperatively performed according to the GLIM criteria for all patients. We analyzed risk factors for treatment failure and poor prognostic factors for RFS using multivariate analyses. RESULTS Treatment failure and recurrence were observed in 50 (17.8%) and 97 (34.5%) of the 281 patients, respectively. The median follow-up period was 52 mo. The treatment failure rate was higher (P = 0.032) and RFS was worse (P = 0.017) in the malnutrition group. In multivariate analyses, GLIM criteria-defined malnutrition was an independent risk factor for treatment failure (odds ratio = 3.110; 95% confidence interval [CI], 1.020-9.470; P = 0.046). Furthermore, severe malnutrition was an independent poor prognostic factor for RFS (hazard ratio = 1.767; 95% CI, 1.132-2.759; P = 0.012). CONCLUSIONS Preoperative malnutrition as defined by the GLIM criteria was an independent risk factor for poor compliance with adjuvant S-1 chemotherapy and a poor prognostic factor for RFS after radical gastrectomy in patients with advanced gastric cancer. <END ABSTRACT>.

Abstract
BACKGROUND There is no consensus on the relation between visceral fat mass and long-term postoperative prognosis in patients with upper gastrointestinal (GI) cancer. OBJECTIVES The purpose of this study was to investigate the association of preoperative visceral fat mass with postoperative complications and overall survival (OS) in patients with upper GI cancer. METHODS We searched MEDLINE, the Cochrane Central Register of Controlled Trials, EMBASE (Dialog), the WHO International Clinical Trials Platform Search Portal, and ClinicalTrials.gov and identified observational studies published from inception through 20 July 2022. We conducted a systematic review and random-effects meta-analysis of studies including patients who were surgically treated for upper GI cancer and whose visceral fat mass was assessed on the basis of body composition. We independently assessed the risk of bias and quality of evidence using the Quality In Prognosis Studies and the Grading of Recommendations, Assessment, Development, and Evaluation approach, respectively. The primary outcome was OS. HRs and 95% CIs for OS were pooled. RESULTS Ninety-one studies (n = 20,583) were included. All studies used computed tomography (CT) to assess the body composition of patients. Twenty-four studies reported the relation between high visceral fat and postoperative outcomes, and their results were synthesized. Compared with low visceral adipose tissue, high visceral adipose tissue assessed by CT may improve OS (HR: 0.69; 95% CI: 0.55, 0.87; I2 = 65%; n = 3407). The risk of bias for OS in each study was moderate or high. The certainty of evidence for OS was very low because of inconsistency in the forest plot, the moderate or high risk of bias, and publication bias. CONCLUSIONS High visceral fat may be associated with improved OS after radical resection in patients with upper GI cancer. Further studies are needed to confirm these findings and mitigate the risk.

Visceral Adipose Tissue Assessment Enhances the Prognostic Value of GLIM Criteria in Patients with Gastric Cancer Undergoing Radical Gastrectomy after Neoadjuvant Treatment. Nutrients 2022; 14:5047. [PMID: 36501076 PMCID: PMC9740239 DOI: 10.3390/nu14235047] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2022] [Revised: 11/20/2022] [Accepted: 11/24/2022] [Indexed: 11/29/2022] Open
Abstract
BACKGROUND The Global Leadership Initiative on Malnutrition (GLIM) criteria has been recently published for diagnosing malnutrition in adults. However, the validity of the GLIM criteria has not been well-established in patients with gastric cancer (GC) treated with neoadjuvant treatment (NT) followed by radical gastrectomy. The present study aimed to explore the prognostic value of GLIM-defined malnutrition before NT and after NT in GC patients and to investigate whether additional visceral adipose tissue (VAT) assessment could improve the predictive power of the GLIM criteria for NT-related adverse events (AEs) and long-term survival. METHODS GC patients who underwent radical surgery after NT from June 2016 to June 2020 were enrolled in this study. The cross-sectional areas of total skeletal muscle (TSM) and VAT were measured using computed tomography (CT) before NT and after NT. GLIM-defined malnutrition was diagnosed using the two-step approach, including nutritional risk screening and diagnostic assessment. Low VAT was also added to the diagnosis of malnutrition in this study. The predictive value of these malnutrition diagnoses for NT-related AEs, and long-term survival was evaluated in GC patients. RESULTS A total of 182 GC patients were included in this study, of which 66 (36.3%) patients before NT and 55 (30.2%) patients after NT were diagnosed with GLIM-defined malnutrition, respectively. In addition to GLIM-defined malnutrition, 54 (29.7%) patients had additional low VAT before NT, and 39 (21.4%) patients had additional low VAT after NT. GLIM-defined malnutrition alone before NT was not associated with NT-related AEs in GC patients. The addition of low VAT to GLIM-defined malnutrition led to a significant predictive value for NT-related AEs. Furthermore, GLIM-defined malnutrition before NT and after NT were both identified as independent risk factors for overall survival (OS) and disease-free survival (DFS). The combination of low VAT and GLIM-defined malnutrition showed a higher hazard ratio for the prediction of OS and DFS both before NT and after NT. CONCLUSIONS The addition of VAT assessment using CT improved the predictive value of GLIM-defined malnutrition for NT-related AEs and long-term survival in GC patients treated with NT followed by radical gastrectomy, which further supports the prognostic importance of assessing adipose tissue simultaneously during the routine nutritional assessment in patients with cancer.

Abstract
PURPOSE This study investigated whether or not the impact of malnutrition, as defined by the Global Leadership Initiative on Malnutrition (GLIM) criteria, on the long-term prognosis after gastrectomy differed between older and young patients with advanced gastric cancer. METHODS This study included patients with primary stage I-III gastric cancer who underwent gastrectomy between April 2008 and June 2018. Patients were divided into normal, moderate, and severe malnutrition groups according to the GLIM criteria for the body mass index (BMI) and body weight loss (BWL). The primary endpoint was the overall survival (OS). RESULTS Of the 512 patients, 274 (53.5%) were included in the younger group (< 70 years old) and 238 (46.5%) in the older group (≥ 70 years old). The prevalence of moderate and severe malnutrition was significantly higher in the older group than in the younger group (P < 0.001 and P = 0.001, respectively). A multivariate analysis showed that moderate malnutrition [hazard ratio (HR) 1.793, P = 0.028] and severe malnutrition (HR 2.374, P = 0.002) were independent prognostic factors in the older group but not in the younger group. CONCLUSION GLIM criteria-defined malnutrition did not correlate with the prognosis in the younger group, whereas moderate and severe malnutrition were independent poor prognostic factors for the OS in the older group.

Abstract
AbstractThe incidence of metabolism-related diseases like obesity and type 2 diabetes mellitus has reached pandemic levels worldwide and increased gradually. Most of them are listed on the table of high-risk factors for malignancy, and metabolic disorders systematically or locally contribute to cancer progression and poor prognosis of patients. Importantly, adipose tissue is fundamental to the occurrence and development of these metabolic disorders. White adipose tissue stores excessive energy, while thermogenic fat including brown and beige adipose tissue dissipates energy to generate heat. In addition to thermogenesis, beige and brown adipocytes also function as dynamic secretory cells and a metabolic sink of nutrients, like glucose, fatty acids, and amino acids. Accordingly, strategies that activate and expand thermogenic adipose tissue offer therapeutic promise to combat overweight, diabetes, and other metabolic disorders through increasing energy expenditure and enhancing glucose tolerance. With a better understanding of its origins and biological functions and the advances in imaging techniques detecting thermogenesis, the roles of thermogenic adipose tissue in tumors have been revealed gradually. On the one hand, enhanced browning of subcutaneous fatty tissue results in weight loss and cancer-associated cachexia. On the other hand, locally activated thermogenic adipocytes in the tumor microenvironment accelerate cancer progression by offering fuel sources and is likely to develop resistance to chemotherapy. Here, we enumerate current knowledge about the significant advances made in the origin and physiological functions of thermogenic fat. In addition, we discuss the multiple roles of thermogenic adipocytes in different tumors. Ultimately, we summarize imaging technologies for identifying thermogenic adipose tissue and pharmacologic agents via modulating thermogenesis in preclinical experiments and clinical trials.

Abstract
OBJECTIVES To evaluate the associations of the radiological features of subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT) with the postoperative complications and overall survival (OS) of patients undergoing laparoscopic radical gastrectomy for gastric cancer. METHODS One hundred forty-two patients underwent laparoscopic radical gastrectomy for gastric cancer from February 2013 to May 2016. The radiological features of SAT and VAT were studied by preoperative computed tomography, and the relationships between the parameters of adipose tissues and the intraoperative and postoperative conditions and OS rate of patients were evaluated. RESULTS A positive linear correlation was found between VAT area and operation duration, and a negative linear correlation was found between VAT density and intraoperative blood loss (p < 0.05 in both). VAT area was an independent risk factor for postoperative complications. VAT area and VAT density were independent risk factors for OS in gastric cancer. CONCLUSIONS A high VAT area was an independent risk factor for postoperative complications of gastric cancer, whereas a low VAT area and high VAT density were independent risk factors for poor prognosis in terms of OS in gastric cancer. KEY POINTS • A large visceral adipose tissue (VAT) area is an unfavourable factor affecting the outcomes of radical gastrectomy for gastric cancer. • Low VAT density may be more likely to cause intraoperative bleeding. • VAT area and VAT density were independent risk factors for the OS of patients with gastric cancer.
