Elderly people and patients with colorectal cancer (CRC) are both at high risk of malnutrition. Therefore, it is of great significance to explore suitable malnutrition screening and diagnostic indicators for elderly patients with CRC. Recently, the Global Leadership Initiative on Malnutrition (GLIM) proposed new diagnostic criteria for malnutrition. The aim of this article was to evaluate the diagnostic value of GLIM criteria for malnutrition in elderly colorectal patients. We explored the relationship between GLIM-malnutrition, post-operative complications and the long-term prognosis of elderly colorectal patients.Elderly patients (aged ≥65 years) who underwent CRC surgery from January 2015 to December 2018 were included. Malnutrition was diagnosed based on the GLIM criteria. The relationships between GLIM-malnutrition and clinical characteristics were analyzed by t-tests, Mann-Whitney U tests, and chi-squared tests. The relationships between GLIM-malnutrition and post-operative complications were analyzed by chi-squared tests, and logistic regression analyses. The relationships between GLIM-malnutrition and the long-term prognosis were analyzed by Kaplan-Meier analyses and logistic and Cox regression analyses.A total of 385 elderly patients were included in this study, and 118 patients (30.65%) were diagnosed with malnutrition according to the GLIM criteria. GLIM-malnutrition was significantly associated with older age, lower body mass index (BMI), lower grip strength, tumor location, higher Nutrition Risk Screening 2002 (NRS-2002), and lower levels of albumin and hemoglobin. GLIM-malnutrition was an independent risk factor [odds ratio (OR): 1.753, 95% confidence interval (CI): 1.100-2.795, P=0.018] for post-operative complications. Cox regression analysis showed that GLIM-malnutrition was an independent risk factor for overall survival in elderly patients with CRC.The GLIM criteria are feasible diagnostic criteria for malnutrition of elderly patients with CRC. GLIM-malnutrition is significantly associated with post-operative complications and overall survival in elderly patients with CRC.
As defined by the Global Leaders Malnutrition Initiative (GLIM), malnutrition is strongly associated with a lower quality of life and poor prognosis in gastric cancer patients. However, few studies have precisely explored the predictors of malnutrition, as defined by the GLIM, for overall survival (OS) after gastric cancer surgery in subgroups of patients stratified according to population characteristics. Our research aimed to analyze whether the predictors of malnutrition defined by the GLIM for postoperative OS in gastric cancer patients differ across subgroups. Patients who underwent radical gastric cancer surgery at our center between July 2014 and February 2019 were included in the study. Propensity score matching (PSM) was used to minimize bias. The study population was divided into malnourished and normal groups based on whether they were malnourished as defined by the GLIM. Univariate and multivariate analyses were performed to identify the risk factors affecting OS. The Kaplan-Meier curve and log-rank test were performed to determine the survival rate difference between subgroups. Overall, 1,007 patients were enrolled in the research. Multivariate analysis showed that malnutrition among the patients was 33.47%. Additionally, GLIM-defined malnutrition was an independent risk factor [hazard ratio (HR): 1.429, P = 0.001] for a shorter OS in gastric cancer patients. Furthermore, subgroup analysis showed that the GLIM was more appropriate for predicting OS in older aged patients (≥65 years), females, those with comorbidities (Charlson comorbidity index ≥ 2), and those with advanced gastric cancer (TNM stage = 3). GLIM-defined malnutrition affects the long-term survival of gastric cancer patients, especially older patients, females, patients with comorbidities, and patients with advanced gastric cancer.
The relationship between liver function and colorectal cancer without liver metastases has not been explored. Therefore, we investigated whether the preoperative albumin-bilirubin grade could predict the prognosis of patients with colorectal cancer (CRC) undergoing radical resection, and we designed a quantifiable predictive model.We retrospectively analyzed data from 284 patients with CRC who underwent radical resection in the Second Affiliated Hospital of the Wenzhou Medical University between January 2011 and January 2016. Patients were divided in two groups according to the calculated cut-off: the high albumin-bilirubin (>-2.48) grade and low albumin-bilirubin (≤-2.48) grade group. Kaplan-Meier curves were constructed to compare the overall survival (OS) between the two groups. Univariate and multivariate analyses were performed to identify the independent risk factors for postoperative complications and OS.Patients with a high albumin-bilirubin grade (n = 165, 58.1%) had a higher rate of postoperative complications (38.2% versus 17.6%, P < 0.001), especially medical (19.4% versus 6.7%, P = 0.002) and severe complications (1.7% versus 7.3%, P = 0.032). They also had a shorter OS (mean survival time, 47.6 versus 54.3 months, P = 0.005), especially patients with tumor-node-metastasis stage III (42.7 months versus 51.6 months, P = 0.036). Age ≥ 70 years (odds ratio [OR] = 2.22, P = 0.003) and high albumin-bilirubin grade (OR = 2.71, P = 0.001) were independent risk factors for postoperative complications, while age ≥ 70 years (hazard ratio [HR] = 2.65, P < 0.001), high albumin-bilirubin grade (HR = 1.81, P = 0.033), tumor-node-metastasis stage II (HR = 13.83, P = 0.010) and III (HR = 23.66, P = 0.002) were independent risk factors of OS.Preoperative albumin-bilirubin grade could predict postoperative complications (especially medical and severe complications) and OS in patients with CRC, especially in those with tumor-node-metastasis stage III.
Abstract Objectives Nutrition status is of great significance to the clinical outcome after major abdominal surgery. However, the effect of preoperative short‐term parenteral nutrition (PN) support among gastric cancer (GC) patients remains unknown and was evaluated in the current study. Methods We retrospectively analyzed 455 nutritionally at‐risk GC patients after radical resection from 2010 to 2016. We matched patients with 3–7 days of PN support to those without PN support. χ 2 And Mann‐Whitney U tests were used to compare differences between the PN and control groups. Results The propensity‐matched sample included 368 GC patients (PN group, n = 184; control group, n = 184). The PN and control groups did not differ regarding postoperative complications ( P = .528). The incidence of anastomotic leakage in the PN group was lower than in the control group ( P = .011), whereas other complications were not found to differ between the groups. The hospitalization cost of the PN group was significantly higher than that of the control group ( P < .001), whereas other outcome indicators were similar. Subgroup analysis showed that short‐term PN support may have an improved benefit for patients with serum albumin level <35 g/L, but not at the level of statistical significance ( P = .17). Conclusion Short‐term PN support did not significantly improve the short‐term clinical outcomes of nutritionally at‐risk GC patients, with the exception of a lower incidence of anastomotic leakage. Considering that short‐term PN support increases economic burden, PN should not be the preferred method among these patients.
Background: The epidemic characteristic of COVID-19 outside Wuhan was still unclear. We report the epidemiological, clinical, treatment and prognosis of COVID-19 in a secondary epidemic area.Methods: This multi-center cohort study included consecutive laboratory-confirmed COVID-19 cases from January 22 to February 22 in Wenzhou, China. All cases were followed up to discharge, or March 16. Data were extracted with standardized form, and compared between severe and non-severe cases. Logistic regression and Cox regression were used to explore the factors associated with ICU admission and hospital stay, respectively.Findings: The whole epidemic lasted for one month. Of the 148 included cases, 29 were severe, and one died. The median age was 52 years, 62·2% were male and 60·8% were overweight or obese. Fever (81·8%) and cough (61·5%) were the most common symptoms. Importantly, 25·0% had no contact history. The median hospital stay was 20 days, and 5·4% were admitted to ICU. Compared with the non-severe cases, the severe patients were older, had higher proportions of smoking, laboratory abnormalities, and ICU admission. Elevated alanine aminotransferase was independently associated with ICU admission; however, type of antiviral drugs had no significant association with duration of hospital stay.Interpretation: The second-generation cases had atypical symptoms, and one quarter had no clear contact history. The prevalence of overweight was high. Strict prevention and control measures were urgent for controlling the outbreak.Funding Statement: National Natural Science Foundation of China, Provincial Natural Science Foundation of Zhejiang, and Science and Technology Planning Project of Wenzhou.Declaration of Interests: None of the authors have any conflict of interest to declare.Ethics Approval Statement: The ethics committees of the designated hospitals approved this retrospective study. Written informed consent was waived.
Background: Peritoneal metastases of gastric cancer are usually detected using imaging, However, the results of imaging modalities are not always reliable; therefore, the prediction of prognosis based on these findings is therefore inaccurate. As visceral obesity has been identified as a potential risk factor for cancer, the present study aimed to evaluate the predictive value of visceral fat area (VFA), a representative marker of visceral obesity, for peritoneal metastasis in patients with gastric cancer and to construct a reliable preoperative prediction system for peritoneal metastasis. Patients and methods: We enrolled 859 patients with gastric cancer. The VFA and other objective clinical tumor characteristics were evaluated using receiver operating characteristic (ROC) curves. Independent predictors of peritoneal metastasis were determined using logistic regression analysis; a prediction system was also evaluated using ROC curves. Results: The ROC curves indicated a VFA cutoff value of 91.00 cm2 as predictive of peritoneal metastasis. On logistic regression, visceral obesity (VFA ≥91.00 cm2) was identified as an independent predictor of peritoneal metastasis, with an area under the ROC curve of 0.659; the platelet-to-lymphocyte ratio (PLR), invasion depth, and vascular invasion were also identified as independent predictors. On integrating these predictors into a single prediction system, peritoneal metastases were more reliably predicted (area under the ROC curve=0.779). Conclusions: Visceral obesity, as defined by the VFA, effectively predicted peritoneal metastases in our cohort. Our scoring system may be a reliable instrument for identifying patients with peritoneal metastasis.
Lymph node involvement significantly impacts the survival of gastric cancer patients and is a crucial factor in determining the appropriate treatment. This study aimed to evaluate the potential of enhanced computed tomography (CT)-based radiomics in predicting lymph node metastasis (LNM) and survival in patients with gastric cancer before surgery.
Background: We aimed to determine whether splenic features change during tumor progression by evaluating the clinicopathological characteristics relevant to splenic density in patients with gastric cancer (GC) and identify a new predictive indicator of prognosis and chemotherapy benefits. Methods: In the present analysis, 408 patients who underwent gastrectomy were included. Density was expressed in mean spleen Hounsfield units on computed tomography. Other clinical characteristics and detailed follow-up data were collected. The cutoff splenic density was 47.8 by the Xtile software. The R software was used for characteristic differential analysis in patients with different splenic densities. The Cox proportional hazards model and forest plot were used for prognosis and chemotherapy benefit analyses. Results: Patients with low splenic density had significantly worse 3-year disease-free survival (DFS) and overall survival (OS) rates (high vs low splenic density: DFS, 63.4% vs 44.6%, p<0.001; OS, 69.8% vs 52.4%, p<0.001). Splenic density showed strong negative correlations with age, number of metastasized lymph nodes, tumor size, and depth of tumor invasion. The benefits of adjuvant chemotherapy were better in the low splenic density group (hazard ratio of OS, 0.546; p=0.001) than in the low-density group (hazard ratio of OS, 0.701; p=0.106). Conclusions: Patients with low splenic density tended to have more advanced tumors and poor prognosis, but better chemotherapy benefits. Splenic density can be regarded as a new indicator of chemotherapy benefits and increase the accuracy of preoperative staging evaluation. Moreover, preoperative evaluation of splenic density may help establish individualized treatment strategies.
The study aimed to investigate the relationship between obesity and postsurgical gastroparesis syndrome (PGS), and to construct a scoring system and a risk model to identify patients at high risk.A total of 634 patients were retrospectively analyzed. Clinical characteristics were evaluated via receiver operating characteristic (ROC) curve analysis. Logistic analysis was performed to determine the independent predictive indicators of PGS. A scoring system consisting of these indicators and a risk-rating model were constructed and evaluated via ROC curve analysis.Based on the ROC curves, the visceral fat area (VFA) cutoff value for PGS was 94.00. Logistic analysis showed that visceral obesity (VFA ≥ 94.00 cm2 ), the reconstruction technique, and tumor size were independent prognostic factors for PGS. The scoring system could predict PGS reliably with a high area under the ROC curve ([AUC] = 0.769). A high-risk rating had a high AUC (AUC I = 0.56, AUC II = 0.65, and AUC III = 0.77), indicating that the risk-rating model could effectively screen patients at high risk of PGS.Visceral obesity defined by VFA effectively predicted PGS. Our scoring system may be a reliable instrument for identifying patients most at risk of PGS.
Gait speed is a clinical outcome that can measure the physical performance of elderly gastric patients. The purpose of this study was to determine the importance of gait speed in predicting post-operative morbidities in elderly patients undergoing curative gastrectomy.We conducted a prospective study of 357 elderly patients (≥65 years old) undergoing curative gastrectomy. Preoperative gait speed was measured in a 6-m well-lit and unobstructed hallway. Patients were followed up for the post-operative clinical outcomes. Factors contributing to the post-operative morbidities were analysed using univariate and multivariate analyses.Slow gait speed was present in 95 out of 357 patients (26.61%) which was significantly associated with age (P < 0.001), gender (P = 0.016), plasma albumin (P < 0.001), American Society of Anesthesiologists grade (P = 0.012), tumour-node-metastasis grade (P = 0.007), sarcopenia (P < 0.001), handgrip (P < 0.001) and post-operative medical complications (P = 0.022). In univariate analysis, age (P = 0.015) and slow gait speed (P = 0.029) were risk factors of post-operative complications. In multivariate analysis, we found that age (P < 0.001) and slow gait speed (P = 0.029) were independent predictors of post-operative medical complications.Slow gait speed is an independent predictor of post-operative medical complications in elderly patients undergoing curative gastrectomy. Those patients should be managed with appropriate perioperative nutritional support and physical exercise which can improve gait speed and reduce the risk of post-operative medical complications.
