Albumin concentrations are primarily determined by the body cell mass and the systemic inflammatory response in cancer patients with weight loss

Association of albumin-bilirubin grade with survival outcomes in patients with cholangiocarcinoma

BACKGROUND

Numerous studies have reported the association between preoperative albumin-bilirubin (ALBI) grade and survival outcomes in patients with cholangiocarcinoma (CCA). However, the results are inconsistent. Therefore, we conducted a meta-analysis to comprehensively evaluate the relationship between ALBI grade and prognosis of CCA patients.

METHODS

We retrieved the databases (Pubmed,Embase and Web of science) to search articles about the association of ALBI grade with prognostic value in CCA patients. Hazard ratios (HR) and 95% confidence intervals (CI) were used to summarize survival outcomes. STATA 12.0 was used to implement the data analyses.

RESULTS

11 studies from 10 articles comprising 2841 patients were included in the meta-analysis. The pooled results showed that high ALBI grade was significantly associated with poor overall survival (OS) (HR: 1.75, 95% CI: 1.32-2.31) and relapse-free survival(RFS)(HR:1.95;95%CI:1.37-2.13). Subgroup analysis further showed that high ALBI grade had better predictive value for Asian population(HR:1.92;95%CI:1.46-2.51). Sensitivity analysis indicated that the results of the meta-analysis were stable.

CONCLUSIONS

High ALBI grade predicted adverse survival outcomes in CCA patients. ALBI grade may be an efficient and convenient prognostic indicator in CCA patients for Asian population.

Controlling nutritional status score as a survival prognosticator in patients with head and neck cancer

PURPOSE

This study aimed to evaluate the prognostic significance of the preoperative Controlling Nutritional Status (CONUT) score in head and neck squamous cell carcinoma (HNSCC).

METHODS

Patients with HNSCC who underwent radical surgery between 2008 and 2017 were retrospectively analyzed and randomly divided into training and validation cohorts by 3:1 ratio. The CONUT score, based on serum albumin, total cholesterol, and lymphocyte count measured within 1 week before surgery, was used. Univariate and multivariate Cox regression identified survival-related variables, forming the basis for predictive models developed in the training cohort and validated in the validation cohort.

RESULTS

A total of 636 patients were enrolled in this study, including 477 patients in the training cohort and 159 patients in validation cohort. A CONUT cutoff value of 2 effectively stratified patients into two distinct prognostic groups with significant survival differences in both the training and validation cohorts. In the multivariate Cox model, a high CONUT score emerged as an independent negative prognosticator of overall survival (OS) and cancer specific survival (CSS) in both training and validation cohorts. The CONUT score-based nomograms accurately predicted OS (concordance index: 0.778 in training cohort and 0.709 in validation cohort) and CSS (concordance index: 0.830 in training cohort and 0.778 in validation cohort).

CONCLUSION

The preoperative CONUT score is a useful prognostic marker for surgically treated HNSCC, enhancing nomogram-based risk models to identify high-risk patients and guide treatment decisions effectively.

Preoperative glasgow prognostic score was an effective prognostic indicator in patients with biliary tract cancer

Background

The Glasgow Prognostic Score (GPS) is a well-established prognostic indicator that effectively reflects the inflammatory, nutritional, and immune status of cancer patients. GPS has been shown to be associated with survival outcomes in many different cancers. However, its prognostic significance in biliary tract cancer (BTC) remains unclear. This meta-analysis aims to explore the prognostic value of GPS in BTC patients.

Methods

A systematic search was conducted in PubMed, Embase, and Web of Science to identify relevant studies. Survival data including overall survival (OS), disease-free survival (DFS) and recurrence-free survival (RFS) were the main observation indicators. Hazard ratios (HRs) with 95% confidence intervals (CIs) were extracted and pooled for meta-analysis.

Results

A total of 16 articles incorporating 1919 patients were included in the study. High GPS was associated with poor OS (HR:2.00, 95% CI:1.62-2.48) and DFS/RFS (HR:2.50, 95% CI:1.71-3.65). Subgroup analysis further confirmed the prognosis value of GPS in BTC patients.

Conclusions

GPS could serves as a valuable prognostic marker in BTC patients and may aid in risk stratification and treatment decision-making.

The Diagnostic and Prognostic Role of Inflammatory Markers, Including the New Cumulative Inflammatory Index (IIC) and Mean Corpuscular Volume/Lymphocyte (MCVL), in Colorectal Adenocarcinoma

Background: Colorectal cancer affects a large number of patients worldwide, with numerous factors being involved in its etiopathogenesis and chronic inflammation playing an essential role in tumor development. In this study, we analyzed and compared several markers of inflammation that are relatively easy to obtain for a rapid and accurate diagnosis and prognosis. Methods: This study included 219 patients diagnosed with colorectal cancer, analyzing the inflammation scores derived from their blood cells and inflammatory circulating proteins. These inflammatory markers are neutrophil-to-lymphocyte ratio-NLR; platelet-to-lymphocyte ratio-PLR; lymphocyte-to-monocyte ratio-LMR; systemic immune inflammation index-SII; systemic inflammatory response index-SIRI; aggregate index of systemic inflammation-AISI; derived neutrophil-to-lymphocyte ratio-dNLR; C-reactive protein-to-albumin ratio-CAR; and fibrinogen-to-albumin ratio-FAR. In the analysis of patients with colorectal cancer, we have also introduced two new recently developed inflammatory markers: the cumulative inflammatory index (IIC) and the ratio between the mean corpuscular volume and lymphocytes (MCVL). This study aimed to correlate the inflammatory markers' levels with the colorectal cancer diagnostic stage, the tumor and clinical characteristics of the colorectal cancer patients, and 36 months' survival time and to evaluate the diagnostic and prognostic capacity and accuracy of these inflammatory markers in this type of cancer. Results: We showed that the levels of the analyzed inflammation markers correlate with the TNM stage, the tumor pathological differentiation grade, the age and gender of the patients, and overall survival, with their increased levels being associated with a lower survival rate. Conclusions: The analyzed markers, which are easy to perform right from the patient's admission, can be helpful both in diagnosis and, mostly, in prognosis, sustaining the role of inflammation in cancer. By comparing them, we showed which one can be useful for increased sensitivity and specificity in the diagnosis and prognosis of colorectal cancer patients.

Predictive value of prognostic nutritional index as prognostic biomarkers in patients with lymphoma: a systematic review and meta-analysis

BACKGROUND

Several research have indicated the significant potential of the Prognostic Nutritional Index (PNI) as a prognostic biomarker in lymphoma patients. However, there is some inconsistency in the findings of a few studies. Hence, to offer a thorough evaluation of the predictive significance of PNI in lymphoma patients, we performed a meta-analysis to examine the prognostic value of PNI for survival outcomes in lymphoma patients.

METHODS

We conducted a comprehensive search for pertinent works published up until December 2023 in databases such as PubMed, EMBASE, Cochrane Library, and Web of Science. We obtained hazard ratio (HR) data related to survival outcomes and computed aggregated HRs with their corresponding 95% confidence intervals (CIs) to evaluate the correlation between PNI and both overall survival (OS) and progression-free survival (PFS) in lymphoma patients.

RESULTS

By analyzing data from 1260 patients in 28 studies, we found that PNI levels were associated with prognosis in lymphoma patients. High PNI levels predicted that patients had longer OS (HR: 0.46, 95% CI 0.37-0.58, P < 0.05) and better PFS (HR: 0.56, 95% CI 0.45-0.70, P < 0.05). Subgroup analyses showed that the predictive ability of PNI for patient prognosis may differ depending on the type of lymphoma. In addition, we found that the critical PNI value had greater predictive potential at 40-45 and above 45.

CONCLUSION

Our study suggests a strong association between PNI and prognostic outcomes in lymphoma patients, indicating that PNI holds substantial prognostic value in this population.

The utilization of hypoalbuminemia as a prognostic metric in patients with spinal metastases: A scoping review

Introduction

Hypoalbuminemia is associated with poor outcomes in cancer patients, but its role in spinal metastases remains unclear.

Research question

This study aimed to identify albumin cutoff values defining hypoalbuminemia and describe the association between serum albumin and outcomes in patients with spinal metastases.

Material and methods

A narrative review of articles up to December 2022 was conducted using PubMed/Medline, EMBASE, and Web of Science databases. Variables extracted included study design, patient characteristics, serum albumin levels, treatments, and levels of evidence. Outcomes included survival/mortality, complications, ambulatory status, readmission, length of stay, discharge disposition, and blood loss.

Results

Thirty-eight studies comprising 21,401 patients were analyzed. Most studies (92%) were Level of Evidence III. Albumin was evaluated as a continuous variable in 18% of studies and as a dichotomous variable in 76%, with 3.5 g/dL being the most common threshold for hypoalbuminemia. Primary outcomes evaluated were survival/mortality (71% of studies), complications (34%), and reoperation/readmission (11%). Of studies examining the association between hypoalbuminemia and survival/mortality, 74% found a significant association. An association between albumin levels and complications was found in 54% of relevant studies.

Discussion and conclusion

The findings of this study suggest that a threshold of 3.5 g/dL seems most appropriate to define hypoalbuminemia in patients with spinal metastases. However, evidence also supports a level-dependent effect. The most consistent significant association was between low albumin and survival at both fixed and continuous time points. There is less evidence to support an association between hypoalbuminemia and other endpoints such as perioperative complications.

Routine Blood Tests as Predictive Tools for Differentiating Follicular Thyroid Carcinoma From Follicular Adenoma

Background

Thyroid cancer is the most common endocrine malignancy, with an increasing incidence rate, particularly among adolescents. Follicular thyroid carcinoma (FTC), though less common than papillary thyroid carcinoma (PTC), presents greater diagnostic challenges, especially when differentiating from follicular adenoma (FA). Current diagnostic methods lack specificity, underscoring the need for a simple, cost-effective predictive model for FTC.This study aimed to develop a predictive scoring system based on routine blood biomarkers to distinguish between FTC and FA, facilitating early diagnosis and treatment.

Methods

A retrospective, single-center case-control study was conducted on patients diagnosed with FTC and FA at Renmin Hospital of Wuhan University from 2016 to 2022. Patients' demographic, clinicopathological characteristics, and preoperative blood biomarker data were analyzed. Statistical tests, including chi-square, t-tests, and Mann-Whitney U-tests, were used to compare biomarkers. Significant variables were included in univariate and multivariate logistic regression analyses, leading to the development of a scoring system. The model's performance was assessed using receiver operating characteristic (ROC) curves.

Results

The study included 23 patients with FA and 26 patients with FTC. Seven blood biomarkers showed significant differences between the groups: ALB, DBIL, TBIL, LYM#, MCHC, RDW-SD, and WBC. Multivariate logistic regression identified ALB and WBC as key predictors, forming a scoring model (Score = 0.54 × ALB - 1.10 × WBC). The model exhibited strong predictive performance (AUC = 0.839), with sensitivity and specificity of 0.808 and 0.826, respectively.

Conclusion

The study developed a novel predictive model using routine blood biomarkers, offering a non-invasive, cost-effective tool for differentiating between FTC and FA. The model has significant clinical potential, providing a feasible alternative to conventional diagnostic techniques. Further multicenter studies and mechanistic investigations are warranted to validate and refine the model, enhancing its utility in clinical practice.

The predictive value of CRP/albumin ratio (CAR) in the diagnosis of ischemia in myocardial perfusion scintigraphy

INTRODUCTION AND OBJECTIVES

Ischemic heart disease (IHD) is the leading cause of mortality worldwide, and finding cheap and accurate screening tests is crucial. This study aimed to evaluate the predictive value of C-reactive protein (CRP)/albumin ratio (CAR) in the diagnosis of IHD using myocardial perfusion imaging (MPI).

METHODS

In this cross-sectional study, a total of 112 patients were investigated to find any relationship between CAR and myocardial ischemia by using myocardial perfusion scintigraphy. Data were analyzed using SPSS, with a P-value below 0.05 considered statistically significant.

RESULTS

Eighty-eight patients had normal MPI. Twenty-two patients had some degree of myocardial ischemia in MPI. The normal MPI and pathological MPI groups were similar in terms of sex, weight, smoking, family history of IHD, albumin levels, diabetes mellitus status, hyperlipidemia, and chest pain type. The CRP, and CAR means in the patients with myocardial ischemia were significantly higher than those with normal MPI.

CONCLUSION

Although the value of CAR was significantly higher in patients with myocardial ischemia compared to subjects with normal MPI and it was an independent predictor of IHD, the capability of CAR in diagnosing myocardial ischemia was not very strong with a sensitivity and specificity of about 60%.

Prognostic Value of Inflammatory and Nutritional Indicators in Non-Metastatic Soft Tissue Sarcomas

Background

Soft tissue sarcoma (STS) has lacked reliable prognostic indicators. This study evaluates blood-based inflammatory and nutritional indexes to identify good predictors for STS outcomes. These indicators included neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), systemic inflammation response index (SIRI), lymphocyte-to-monocyte ratio (PNI), albumin-to-globulin ratio (AGR), and platelet-to-albumin ratio (PAR).

Methods

A total of 93 were included, and blood indexes were measured preoperatively. Univariate and multivariate regression analyses identified significant predictors, and model performance was assessed using the Akaike Information Criterion (AIC), Bayesian Information Criterion (BIC), Concordance Index (C-index), and Likelihood Ratio Chi-Square (LR_χ2).

Results

Univariate analysis indicated that NLR, PLR, LMR, SIRI, AGR, and PAR show potentially significant differences (P<0.01), except for PNI. Further analysis showed that SIRI and AGR have a high C-index, LR_χ2, and -2 log-likelihood, lower AIC and BIC, indicating a better model fit for overall survival (OS) and disease-free survival (DFS). The combination index of the SIRI+AGR+Enneking stage achieved the best accuracy (C-index: 0.751 for DFS; C-index: 0.755 for OS). Multivariate regression showed higher Enneking staging (HR=2.720, P=0.038), lower AGR (HR=2.091, P=0.014), and higher SIRI (HR=2.078, P=0.034) as independent prognostic factors for DFS. Meanwhile, low AGR (HR=3.729, P=0.034), and high SIRI (HR=3.729, P=0.016) remained independent prognostic factors for OS.

Conclusion

Preoperative SIRI is a better predictive index compared to NLR, PLR, and LMR. Preoperative SIRI and AGR are independent risk factors for both DFS and OS. The combination index of the SIRI+AGR+Enneking stage provides a more robust prediction of clinical prognosis in STS patients.

PCT/ALB Ratio in Initial Three days for the Prediction of Secondary Infection in Septic Patients

Background

Procalcitonin (PCT) to albumin (ALB) ratio (PAR) in initial three days is a rapidly available indicator to assess the prognosis of patients with sepsis. This study aims to explore the correlation between changes in PAR during the initial 72 hours and the incidence of secondary infections.

Methods

A total of 147 patients with sepsis were included in this study. Patients divided into secondary infection and without secondary infection group, according to whether they had secondary infection. PAR was calculated as serum PCT (ng/mL)/ALB (mg/mL). All statistical analyses were performed using the statistical package SPSS 20.0.

Results

Compared with the without secondary infection group, the median APACHE II (22[17-30] vs 16[11-25]; p=0.009) were significantly higher in the secondary infection group. And the median ΔPCT/ALB adm-72h (0.10[0.02-0.48] vs 0.17[0.03-0.65]; p=0.011) were significantly lower in the secondary infection group. On multiple logistic regression, lower ΔPCT/ALB adm-72h was independently associated with the secondary infection. Decreasing quartile of ΔPCT/ALB adm-72h was statistically significantly associated with secondary infection, particularly among survivors.

Conclusion

The decline in the PCT/ALB ratio over the initial 72 hours of the acute phase of sepsis serves as an association for the onset of secondary infections during a septic patient's hospitalization.

Advancing Nutritional Care Through Bioelectrical Impedance Analysis in Critical Patients

Nutritional support in critically ill patients has been acknowledged as a pillar of ICU care, playing a pivotal role in preserving muscle mass, supporting immune function, and promoting recovery during and after critical illness. Providing effective nutritional support requires adapting it to the patient's diagnosis, unique characteristics, and metabolic state to minimize the risks of overfeeding or underfeeding while mitigating muscle loss. This level of care requires a comprehensive nutritional assessment and the establishment of a nutrition-focused protocol. Regular, consistent and detailed nutritional evaluation can influence both therapeutic decisions and clinical interventions, thus ensuring that the specific needs of critically ill patients are met from the acute phase through their entire recovery process. Bioelectrical impedance analysis (BIA) is increasingly recognized as a valuable tool for enhancing nutritional care in critically ill patients. By delivering precise, real-time insights into key aspects of body composition, BIA is thought to provide clinicians with a more comprehensive understanding of the complex physiological changes that occur during critical illness. This narrative review highlights the potential of BIA in offering these precise assessments, facilitating the development of more accurate and personalized nutritional strategies for critically ill patients. If BIA can reliably assess dynamic shifts in hydration and tissue integrity, it holds the promise of further advancing individualized care and optimizing clinical outcomes in this vulnerable population.

Enhancing predictive accuracy for urinary tract infections post-pediatric pyeloplasty with explainable AI: an ensemble TabNet approach

Ureteropelvic junction obstruction (UPJO) is a common pediatric condition often treated with pyeloplasty. Despite the surgical intervention, postoperative urinary tract infections (UTIs) occur in over 30% of cases within six months, adversely affecting recovery and increasing both clinical and economic burdens. Current prediction methods for postoperative UTIs rely on empirical judgment and limited clinical parameters, underscoring the need for a robust, multifactorial predictive model. We retrospectively analyzed data from 764 pediatric patients who underwent unilateral pyeloplasty at the Children's Hospital affiliated with the Capital Institute of Pediatrics between January 2012 and January 2023. A total of 25 clinical features were extracted, including patient demographics, medical history, surgical details, and various postoperative indicators. Feature engineering was initially performed, followed by a comparative analysis of five machine learning algorithms (Logistic Regression, SVM, Random Forest, XGBoost, and LightGBM) and the deep learning TabNet model. This comparison highlighted the respective strengths and limitations of traditional machine learning versus deep learning approaches. Building on these findings, we developed an ensemble learning model, meta-learner, that effectively integrates both methodologies, and utilized SHAP(Shapley Additive Explanation, SHAP) to complete the visualization of the integrated black-box model. Among the 764 pediatric pyeloplasty cases analyzed, 265 (34.7%) developed postoperative UTIs, predominantly within the first three months. Early UTIs significantly increased the likelihood of re-obstruction (P < 0.01), underscoring the critical impact of infection on surgical outcomes. In evaluating the performance of six algorithms, TabNet outperformed traditional models, with the order from lowest to highest as follows: Logistic Regression, SVM, Random Forest, XGBoost, LightGBM, and TabNet. Feature engineering markedly improved the predictive accuracy of traditional models, as evidenced by the enhanced performance of LightGBM (Accuracy: 0.71, AUC: 0.78 post-engineering). The proposed ensemble approach, combining LightGBM and TabNet with a Logistic Regression meta-learner, achieved superior predictive accuracy (Accuracy: 0.80, AUC: 0.80) while reducing dependence on feature engineering. SHAP analysis further revealed eGFR and ALB as significant predictors of UTIs post-pyeloplasty, providing new clinical insights into risk factors. In summary, we have introduced the first ensemble prediction model, incorporating both machine learning and deep learning (meta-learner), to predict urinary tract infections following pediatric pyeloplasty. This ensemble approach mitigates the dependency of machine learning models on feature engineering while addressing the issue of overfitting in deep learning-based models like TabNet, particularly in the context of small medical datasets. By improving prediction accuracy, this model supports proactive interventions, reduces postoperative infections and re-obstruction rates, enhances pyeloplasty outcomes, and alleviates health and economic burdens.Level of evidence IV Case series with no comparison group.

Erythrocyte modified controlling nutritional status as a biomarker for predicting poor prognosis in post-surgery breast cancer patients

Nutrition and inflammation are closely related to prognosis in breast cancer patients. However, current nutritional and inflammatory measures predict disease free survival (DFS) of breast cancer are still different, and the most predictive measures remain unknown. This study aimed to compare the predictive effects of commonly used nutritional and inflammatory measures on DFS and to improve existing nutritional or inflammatory measures in order to develop a new model that is more effective for predicting postoperative recurrence and metastasis in breast cancer patients. The clinical data of 536 female breast cancer patients with invasive ductal carcinoma who underwent surgery at Shaoxing People's Hospital from January 2012 to December 2018 were retrospectively evaluated. The predictive effects of nutritional and inflammatory indicators on DFS were evaluated. Machine learning was used to evaluate and rank laboratory indicators, select relatively important variables to modify nutritional or inflammatory indicators with the best predictive power, and evaluate their predictive role in patients' postoperative recurrence and metastasis. Among various metrics predicting DFS, the CONUT score emerged paramount with an area under the curve (AUC) of 0.667. Interestingly, the combination of the erythrocyte levels with the CONUT score (ECONUT) achieved the highest AUC (0.722). The Kaplan-Meier survival analysis showed that the group exhibiting high ECONUT scores experiencing a notably poorer DFS. ECONUT was identified as an independent risk factor for postoperative DFS (P < 0.001). The ECONUT model could provide an effective assessment tool for predicting DFS in breast cancer patients.

Prediction of preoperative peritoneal cancer index for pseudomyxoma peritonei by multiple linear regression analysis

Background

The aim of the present study was to establish a predictive model to predict the peritoneal cancer index (PCI) preoperatively in patients with pseudomyxoma peritonei (PMP).

Methods

A total of 372 PMP patients were consecutively included from a prospective follow-up database between 1 June 2013 and 1 June 2023. Nine potential variables, namely, gender, age, Barthel Index (BAI), hemoglobin (Hb), albumin (Alb), D-dimer, carcinoembryonic antigen (CEA), carbohydrate antigen 125 (CA 125), and CA 19-9, were estimated using multiple linear regression (MLR) analysis with a stepwise selection procedure. The established MLR model was internally validated using K-fold cross-validation. The agreement between the predicted and surgical PCI was assessed using Bland–Altman plots and intraclass correlation (ICC). A p-value of less than 0.05 was considered statistically significant.

Results

Six independent predictors were confirmed by the stepwise MLR analysis with an R2 value of 0.570. The predicted PCI formula was represented as follows: PCI = 19.567 + 2.091 * Gender (male = 1, female = 0) − 0.643 * Alb +4.201 * Lg (D-dimer) + 2.938 * Lg (CEA) + 5.441 * Lg (CA 125) + 1.802 * Lg (CA 19-9). The agreement between predicted and surgical PCI was assessed using Bland–Altman plots, showing a limit of agreement (LoA) between −15.847 (95%CI: −17.2646 to −14.4292) and +15.847 (95%CI: 14.4292–17.2646).

Conclusion

This study represents the first attempt to use an MLR model for the preoperative prediction of PCI in PMP patients. Nevertheless, the MLR model did not perform well enough in predicting preoperative PCI. In the future, more advanced statistical techniques and a radiomics-based CT-PCI-participated MLR model will be developed, which may enhance the predictive ability of PCI.

Prognostic significance of hemoglobin, albumin, lymphocyte and platelet score in solid tumors: a pooled study

Objective

The high hemoglobin, albumin, lymphocyte, and platelet (HALP) score has been reported to be a good prognostic indicator for several malignancies. However, more evidence is needed before it can be introduced into clinical practice. Here, we systematically evaluated the predictive value of HALP for survival outcomes in patients with solid tumors.

Methods

This study was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and Assessing the Methodological Quality of Systematic Reviews (AMSTAR) Guidelines. In March 2024, an electronic literature search was performed for articles regarding the prognostic role of HALP in solid tumors. Data from studies with reported risk ratios (HRs) and 95% confidence intervals (CIs) were pooled in a meta-analysis. Study bias was assessed using the QUIPS tool.

Results

Of the 729 articles reviewed, 45 cohorts including data from 17,049 patients with cancer were included in the pooled analysis. The pooled results demonstrated that elevated HALP score was significantly associated with favorable overall survival (HR = 0.60, 95% CI 0.54-0.67, p < 0.01), cancer-specific survival (HR = 0.53, 95% CI 0.44- 0.64, p < 0.01), progression-free survival (HR = 0.62, 95% CI 0.54-0.72, p < 0.01), recurrence-free survival (HR = 0.48, 95% CI 0.30-0.77, p < 0.01), and disease-free survival (HR = 0.72, 95% CI 0.57-0.82, p < 0.01). Subgroup analyses based on various confounding factors further revealed the consistent prognostic impact of HALP on overall survival in patients with solid tumors.

Conclusions

Our findings suggest that high HALP is associated with better survival outcomes in patients. The HALP score is a potential prognostic biomarker in solid tumors, but it needs to be further studied whether it can improve the established prognostic model.

Nomogram model based on γ-glutamyl transferase to albumin ratio predicts survival in hepatocellular carcinoma patients with transarterial chemoembolization treatment

BACKGROUND

The development of tumor is closely linked to inflammation. Therefore, targeting molecules involved in inflammation may be effective in predicting cancer prognosis. Transarterial chemoembolization (TACE) holds significant therapeutic significance in addressing hepatocellular carcinoma (HCC). At present, no studies have evaluated the predictive value of γ-glutamyl transferase to albumin ratio (GAR) on the prognosis of HCC undergoing TACE.

AIM

To explore the potential prognostic significance of the GAR in individuals undergoing TACE for HCC.

METHODS

A total of 1231 patients from seven hospitals in China were randomized into a training cohort (n = 862) and a validation cohort (n = 369). To establish independent prognostic factors for overall survival (OS), we utilized multivariate and univariate Cox regression models. The best cut-off value of the GAR was determined with the X-tile software, with OS as the basis. Validations were performed using dual therapy cohort and triple therapy cohort.

RESULTS

X-tile software revealed a GAR threshold of 4.75 as optimal. Both pre- and post-propensity score matching analyses demonstrated that the median OS in the low-GAR group (< 4.75) was notably longer compared to the high-GAR group (≥ 4.75), showing results of 26.9 vs 9.8 months (P < 0.001) initially, and 18.1 vs 11.3 months (P < 0.001) after match. Furthermore, multivariate analysis identified GAR ≥ 4.75 as an independent prognostic factor (P < 0.001). The receiver operating characteristic curves for the nomogram showed area under receiver operating characteristic curves of 0.741, 0.747, and 0.708 for predicting 1-, 2-, and 3-year survival, respectively. Consistent findings were reiterated in the two cohorts involving TACE in combination with targeted therapy and TACE in combination with targeted therapy and immunotherapy. Calibration curve and decision curve analyses substantiated the model's relatively robust predictive capabilities.

CONCLUSION

Our study validates the effective prognostic capacity of the GAR-based nomogram for HCC patients undergoing TACE or TACE in combination with systemic therapy.

Is nutritional status a new indicator to use in clinical practice for colorectal cancer patients?

In this editorial we comment on the interesting article by Liu et al. The topic of discussion is the need for a cost-effective and easy-to-use scoring system for predicting the prognosis of colorectal cancer patients. In this context, nutritional assessment plays a crucial role in the multimodal evaluation of patients. In particular, the controlling nutritional status score was found to be an effective tool in the clinical decision-making process, in order to customize treatment strategies and to improve patient outcomes.

Hypoalbuminemia is Associated with Higher 90-Day Mortality and Poor Prognosis in Patients with Esophageal Squamous Cell Carcinoma and Liver Cirrhosis Receiving Radiotherapy-Based Therapy

Background

Liver cirrhosis (LC) is common among patients with esophageal squamous cell carcinoma (ESCC) due to shared etiologic factor, alcohol. For non-metastatic ESCC (nmESCC) patients with cirrhosis, surgery is often contraindicated or associated with high morbidity, therefore radiotherapy-based therapy was commonly applied. This study aims to investigate prognosticators for overall survival (OS) in nmESCC and cirrhotic patients receiving radiotherapy-based therapy. Furthermore, we will also evaluate the predictors for the 90-day mortality rate to reduce avoidable treatment-related toxic effects, and prevent medical waste.

Methods

Between January 2001 and December 2021, we retrospectively reviewed medical records of 1298 ESCC patients. Total 78 patients with nmESCC and liver cirrhosis identified based on abdominal ultrasonography, computerized tomography, or liver biopsy were enrolled. Clinicopathologic parameters were collected and correlated with OS and 90-day mortality.

Results

Univariate analysis revealed that Child-Pugh classification B/C (P<0.001, versus A), radiotherapy alone (P=0.03, versus chemoradiotherapy), prothrombin time (PT) prolonged≧2 seconds (P=0.024), albumin≦3.5g/dl (P<0.001), controlled/refractory ascites (P=0.01, versus none of ascites), and total bilirubin≧1.5mg/dl (P=0.004) were significantly associated with inferior OS. In multivariate analyses, albumin≦3.5g/dl (P=0.001, odds ratio (OR): 2.500) and total bilirubin≧1.5mg/dl (P=0.019, OR: 2.012) were independent adverse prognosticators. The 90-day mortality in these 78 patients receiving radiotherapy-based therapy was 10.3% (n=8), including ESCC progression in 4 patients, liver failure in 1 patient, and others in 3. Clinical 8th American Joint Committee on Cancer (AJCC) stage IVA (P=0.02), clinical T classification T3/4 (P=0.049), PT prolonged≧4 seconds (P=0.009), and albumin≦3.5g/dl (P=0.027) were significantly correlated with higher 90-day mortality. Logistic model showed albumin≦3.5g/dl (P=0.015, OR: 16.129) and clinical 8th AJCC stage IVA (P=0.012, OR: 17.544) were independently correlated with higher 90-day mortality.

Conclusion

Hypoalbuminemia is associated with higher 90-day mortality and poor prognosis in nmESCC and liver cirrhosis patients receiving radiotherapy-based therapy.

The association between an inflammation-based nutritional tool (Glasgow Prognostic Score) and length of hospital stay in patients with haematological cancer

BACKGROUND

This is a retrospective study to identify if Glasgow Prognostic Score (GPS) is associated with length of hospital stay (LOS) in haematological cancer.

METHODS

The participants were adult inpatients at a single centre in between 2018 and 2022. Serum levels of CRP and albumin were measured at admission. GPS was calculated as follows: point "0" as CRP < 10 mg/L and albumin ≥ 35 g/L; point "2" as CRP ≥ 10 mg/L and albumin < 35 g/L; point "1" as either CRP ≥ 10 mg/L or albumin < 35 g/L. Patients with point "0" were classified as low risk whilst point "2" as high risk. LOS was defined as the interval between the admission and discharge date.

RESULTS

As a result, the average age was 59.6 ± 12.6 years and the average LOS was 6.0 days (IQR = 2 days, 11 days). Of 1621 patients, 8.8% of them were high risk. GPS was associated with LOS (β = 2.7 days; 95% CI = 0.8 days, 4.6 days; p trend < 0.001) after full adjustment. Each point of GPS was associated with 1.9 days (95% CI = 1.4 days, 2.4 days) longer in LOS with full adjustment. The association was more prominent in younger patients (< 65 years), patients with leukaemia and myelodysplastic syndrome, and those with normal body weight status (18.5-24 kg/m2), compared with their counterparts.

CONCLUSION

GPS was associated with LOS in Chinese patients with haematological cancer, indicating GPS could be a useful tool to predict outcome.

Impact of preoperative haemoglobin, albumin, lymphocyte, and platelet score on oral cancer prognosis

OBJECTIVE

To evaluate the preoperative haemoglobin, albumin, lymphocyte, and platelet score as a prognostic indicator in oral squamous cell carcinoma treated by radical surgery.

SUBJECTS AND METHODS

Patients (83 men, 32 women; 65.80 ± 11.47 years) who underwent radical surgery between 2012 and 2022 were included. Factors affecting overall survival and disease-free survival according to the haemoglobin, albumin, lymphocyte, and platelet score were examined. Patients were categorised into low- and high-score groups using optimal cut-off values obtained from receiver operating characteristic curve analysis.

RESULTS

The low-score group had poorer overall and disease-free survival (p < 0.001 each). Multivariate analysis identified alcohol consumption (hazard ratio [HR], 3.83; 95% confidence interval [CI]: 1.56-9.41, p = 0.003); vascular invasion (HR, 3.97; 95% CI: 1.60-9.85, p = 0.003); and the haemoglobin, albumin, lymphocyte, and platelet score (HR, 0.39; 95% CI: 0.20-0.78, p = 0.007) as independent prognostic factors for overall survival and vascular (HR, 3.66; 95% CI: 1.79-7.50, p < 0.001) and lymphovascular (HR, 2.44; 95% CI: 1.36-4.41, p = 0.003) invasion as independent prognostic factors for disease-free survival.

CONCLUSION

The preoperative haemoglobin, albumin, lymphocyte, and platelet score may be a significant prognostic factor for patients with oral squamous cell carcinoma undergoing radical surgery.

Combined influence of physical activity and C-reactive protein to albumin ratio on mortality among older cancer survivors in the United States: a prospective cohort study

BACKGROUND

Although a high C-reactive protein-to-albumin ratio (CAR) is believed to increase mortality risk, the association between the physical activity (PA), CAR, and mortality among cancer survivors has not been investigated. This study aimed to examine this association among cancer survivors in the United States.

METHODS

This cohort study used data from the National Health and Nutrition Examination Survey from 1999 to 2010. PA was self-reported using the Global Physical Activity Questionnaire, and C-reactive protein and albumin levels were obtained from laboratory data files. Mortality data were obtained by linkage of the cohort database to the National Death Index as of December 31, 2019. The analysis was conducted from November 1 to December 31, 2023. We used Cox proportional hazards multivariable regression to assess hazard ratios (HRs) and 95% confidence interval (CIs) for total and cancer-specific mortality risks attributable to PA and CAR.

RESULTS

Among 2,232 cancer survivors, 325 (14.6%) reported no PA with a high CAR. During a follow-up of up to 20.75 years (median, 12.3 years; 27,453 person-years), 1,174 deaths occurred (cancer, 335; other, 839). A high CAR was observed to be consistently associated with the highest risks of total (HR, 1.59; 95% CI, 1.37-1.85) and cancer-specific (HR, 2.06; 95% CI, 1.55-2.73) mortality compared with a low CAR in a series of adjusted models. Multivariable models showed that PA was associated with a lower risk of all-cause (HR, 0.60; 95% CI, 0.52-0.69) and cancer-specific (HR, 0.64; 95% CI, 0.49-0.84) mortality compared with no PA. In the joint analyses, survivors with PA ≥ 600 metabolic equivalent min/wk and a low CAR were more likely to reduce the risk of total (HR, 0.41; 95% CI, 0.32-0.51) and cancer-specific (HR, 0.32; 95% CI, 0.20-0.50) mortality by 59% and 68% compared with those with no PA and a high CAR.

CONCLUSION

The pairing of adequate PA and a low CAR was significantly associated with reduced all-cause and cancer-related mortality risks.

Effectiveness of prognostic nutritional index in predicting overall survival and evaluating immunotherapy response in anaplastic thyroid carcinoma

BACKGROUND

The prognostic value of nutritional status in anaplastic thyroid carcinoma (ATC) remains unclear. The Prognostic Nutritional Index (PNI) is a reliable indicator of overall nutritional and immune status, and it has emerged as a significant prognostic factor in various malignancies. This study aimed to explore the utility of PNI in ATC.

METHODS

We systematically reviewed ATC patients in our institute from January 2000 to June 2023 and categorized them into high and low PNI groups based on the median PNI value. Kaplan-Meier analysis and Cox regression were employed to assess the impact of PNI on overall survival, while ROC curve analysis evaluated the predictive value of PNI. Mimics software was used for three-dimensional reconstruction of pre- and post-immunotherapy tumor volumes, enabling the assessment of treatment response.

RESULTS

A total of 77 ATC patients were included in this study. Low baseline PNI was associated with significantly shorter overall survival (1-year survival rate: 5.26% vs 30.77%; median survival time: 5.30 months vs 8.87 months). The 1-year, 2-year, and 3-year AUC values for PNI were 0.82, 0.79, and 0.77, respectively. In the multivariate analysis, both PNI and tumor size emerged as independent prognostic factors for patient overall survival. Among ATC patients receiving 2-3 cycles of immunotherapy, an increase in post-treatment PNI levels was positively correlated with a reduction in tumor volume.

CONCLUSION

PNI is an independent predictor of overall survival and holds the potential to serve as a valuable indicator for assessing and predicting immunotherapy efficacy in ATC patients.

High Systemic Inflammatory Protein Index Is Associated with Clinically Ineffective Reperfusion in Acute Anterior Circulation Ischemic Stroke Patients Undergoing Endovascular Treatment

Nearly half of the patients undergoing endovascular treatment (EVT) do not have favorable outcomes despite successful recanalization of the occluded artery, which is also known as clinically ineffective reperfusion. We proposed a novel index-the systemic inflammatory protein index (SIPI), based on albumin, globulin, and C-reaction protein (CRP). We aimed to evaluate the relationship between inflammatory biomarkers at varying time points and the 90-day functional outcomes and investigate inflammatory biomarkers' dynamic changes during hospitalization in acute ischemic stroke (AIS) patients of anterior circulation undergoing EVT. We retrospectively recruited consecutive patients diagnosed with AIS of anterior circulation and treated with EVT from January 2018 to June 2022 in Nanfang Hospital. Albumin, globulin, and CRP were recorded on admission, 1 day, 3 days, and 7 days after EVT. An unfavorable functional outcome was defined as 90-day modified Rankin Scale (mRS) of 3-6. Albumin-to-globulin ratio (AGR), C-reactive protein-to-albumin ratio (CAR), and SIPI were calculated as follows: AGR = albumin/globulin; CAR = CRP/albumin; SIPI = CRP × globulin/albumin. A total of 238 consecutive anterior circulation AIS patients with EVT were included, among which 145 (60.9%) patients had unfavorable outcomes. After adjusting for confounding factors, admission globulin, admission AGR, 1-day AGR, 3-day albumin, 3-day CRP, 3-day CAR, 3-day SIPI, 7-day albumin, 7-day CRP, 7-day CAR, and 7-day SIPI showed an independent association with 90-day functional outcome. Of them, 3-day SIPI had the most robust discriminative ability with an area under the curve of 0.719 (CI 0.630-0.808, p < 0.001). There were differences in the dynamic change of inflammatory biomarkers between the subjects with favorable and unfavorable functional outcomes. Inflammatory biomarkers, including albumin, globulin, CRP, AGR, CAR, and SIPI, are independent predictors of 90-day unfavorable outcomes in anterior circulation AIS patients with EVT. SIPI of day 3 has the highest predictive value.

The early prognostic value of the 1-4-day BCM/PA trend after admission in neurocritical patients

The purpose of this study was to investigate early stage dynamic changes in relevant indicators in neurocritical patients to identify biomarkers that can predict a poor prognosis at an early stage (1-4 days after admission). This study retrospectively collected clinical data, inflammatory indicators, and nutritional indicators from 77 patients at the neurology intensive care unit. The 3-month modified Rankin scale score was used as the outcome indicator. A linear mixed model was used to analyze changes in inflammatory indicators and nutritional indicators in neurocritical patients over time from 1-4 days after admission. Logistic regression was used to determine the independent risk factors for a poor prognosis in neurocritical patients and to construct a predictive model. The predictive efficacy of the model was verified using leave-one-out cross-validation and decision curve analysis methods. The analysis results showed that 1-4 days after admission, the inflammatory indicators of white blood cell and absolute monocyte counts and the nutritional indicators of body cell mass(BCM), fat-free mass, body cell mass/phase angle (BCM/PA), intracellular water, extracellular water, and skeletal muscle index increased overall, while the nutritional indicators of albumin and visceral fat area decreased overall. The logistic multivariate regression model showed that the Charlson comorbidity index (CCI) (odds ratio (OR) = 2.526, 95% CI [1.202, 5.308]), hemoglobin (Hb)(on admission)-Hb(min) (OR = 1.049, 95% CI [1.015, 1.083), BCM(on admission) (OR = 0.794, 95% CI [0.662, 0.952]), and the change in BCM/PA 1-4 days after admission (OR = 1.157, 95% CI [1.070, 1.252]) were independent risk factors for a poor prognosis in neurocritical patients. The predictive analysis showed that the predictive power of Model 1 with BCM/PA (area under the curve (AUC) = 0.95, 95% CI (0.90, 0.99)) was 93%, 65%, 141%, and 133% higher than that of Model 2 without BCM/PA, the CCI, the APACHE II score, and the NRS2002 score (all P < 0.05), respectively. The CCI, Hb(on admission)-Hb(min), BCM(on admission), and an increase in BCM/PA 1-4 days after admission were independently associated with a poor prognosis in neurocritical patients. Of these variables, BCM/PA may be a valid indicator for early stage prediction of a poor prognosis in neurocritical patients.

Prognostic and clinicopathological value of the controlling nutritional status (CONUT) score in patients with head and neck cancer: a meta-analysis

BACKGROUND

The efficiency of controlling nutritional status (CONUT) score in detecting the prognosis of head and neck cancer (HNC) patients has been investigated in some works, but no consistent findings are obtained. Therefore, this work focused on evaluating the precise prognostic role of CONUT for HNC patients through meta-analysis.

METHODS

The effect of CONUT on predicting the prognosis of HNC patients was evaluated through calculating combined hazard ratios (HRs) as well as 95% confidence intervals (CIs). The correlations of CONUT with clinicopathological features of HNC patients were investigated through combined odds ratios (ORs) and 95%CIs. This study used the random-effects model in the case of significant heterogeneity; or else, we selected the fixed-effects model.

RESULTS

There were eight articles involving 1,478 patients enrolled for the current meta-analysis. We adopted the fixed-effects model for OS and DFS analysis because of the non-significant heterogeneity. As demonstrated by our combined findings, high CONUT score could significantly predict the poor overall survival (OS) (HR = 1.94, 95%CI = 1.55-2.44, p < 0.001) and disease-free survival (DFS) (HR = 1.93, 95%CI = 1.45-2.56, p < 0.001) of HNC. In addition, higher CONUT score was significantly connected to T3-T4 stage (OR = 3.21, 95%CI = 1.94-5.31, p < 0.001) and N1-N3 stage (OR = 3.10, 95%CI = 1.74-5.53, p < 0.001).

CONCLUSION

According to findings in the present meta-analysis, high CONUT score significantly predicted the prognosis of OS and DFS for HNC patients. Higher CONUT score was also correlated to larger tumor size and LN metastasis in HNC. Due to it is a cost-effective and easily available parameter, CONUT could serve as promising prognostic biomarker for HNC.

Effects of nutritional interventions on cancer patients receiving neoadjuvant chemoradiotherapy: a meta-analysis of randomized controlled trials

BACKGROUND

Malnutrition commonly occurs in cancer patients, impacting their quality of life and survival duration. The objective of this meta-analysis and systematic review is to assess the effects of nutritional interventions on patients undergoing neoadjuvant chemoradiotherapy.

METHODS

A comprehensive search was conducted in PubMed, Embase, and the Cochrane Library databases to obtain randomized controlled trials of nutritional interventions in patients with neoadjuvant chemoradiotherapy. Outcomes assessed included toxicity reactions to neoadjuvant therapy, levels of inflammation-related markers, nutritional status, and relevant clinical outcomes. The relative risk (RR) or weighted mean difference (WMD) and 95% confidence interval (CI) were used as effect sizes.

RESULTS

A total of 16 studies were included, involving 954 patients. Nutritional intervention significantly reduced the incidence of vomiting (RR = 0.37, 95%CI: 0.21-0.67, P = 0.001) and mucositis (RR = 0.82, 95%CI: 0.67-1.00, P = 0.046) in patients with neoadjuvant chemoradiotherapy. For the nutritional status of cancer patients, nutritional intervention significantly increased the proportion of well-nourished patients (RR = 12.74, 95%CI: 4.43-36.69, P < 0.001). In addition, nutritional intervention also reduced the length of hospital stay in neoadjuvant chemoradiotherapy patients after surgery (WMD =  - 0.82, 95%CI: - 1.61- - 0.02, P = 0.043). However, there was no improvement in nausea (P = 0.534), diarrhea (P = 0.068), febrile neutropenia (P = 0.551), levels of albumin (P = 0.211), prealbumin (P = 0.063), C-reactive protein (P = 0.430), clinical remission (P = 0.148), or postoperative complications (P = 0.098).

CONCLUSION

Nutritional intervention can reduce the toxicity of neoadjuvant chemoradiotherapy (vomiting and mucositis), improve the nutritional status of patients, and shorten the length of postoperative hospital stay. Well-designed and high-quality studies are necessary to confirm the effect of nutritional interventions on cancer patients, with a specific focus on reaching nutritional goals and providing the right nutrients.

Predictive values of sarcopenia and systemic inflammation-based markers in advanced hepatocellular carcinoma after hepatectomy

BACKGROUND

Sarcopenia accompanied by systemic inflammation is associated with poor prognosis in patients with advanced hepatocellular carcinoma (HCC). However, the effect of sarcopenia combined with systemic inflammation on the prognosis of patients with advanced HCC who underwent hepatectomy is unclear. This study aimed to evaluate the effect of sarcopenia and inflammation on the prognosis of patients with advanced HCC.

METHODS

This retrospective study included 151 patients recruited between July 2010 and December 2022. We defined advanced HCC as that presenting with vascular invasion or tumor size ≥2 cm or multiple tumors. Sarcopenia was assessed using the psoas muscle index. Preoperative inflammatory markers were used by calculating the prognostic nutritional index, albumin-globulin ratio (AGR), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio. Cox regression analysis was performed to determine the prognostic factors for overall survival.

RESULTS

Of 151 patients, sarcopenia occurred in 84 (55.6 %). Sarcopenia was significantly associated with male sex, older age, body mass index (<25 kg/m2), and a higher NLR. In the multivariate analysis, AGR <1.25 (hazard ratio [HR], 2.504; 95% confidence interval [CI]: 1.325-4.820; p < 0.05); alpha-fetoprotein levels ≥25 ng/mL (HR, 1.891; 95% CI: 1.016-3.480; p = 0.04); and sarcopenia (HR, 1.908; 95% CI: 1.009-3.776; p < 0.05) were independent predictors of overall survival. The sarcopenia and low AGR groups had significantly worse overall survival than either the non-sarcopenia and high AGR or sarcopenia and low AGR groups.

CONCLUSION

Sarcopenia and AGR are independent prognostic factors in patients with advanced HCC. Thus, sarcopenia may achieve a better prognostic value when combined with AGR.

Role of modified Glasgow Prognostic Score in patients with achalasia who underwent laparoscopic Heller-myotomy with Dor-fundoplication

BACKGROUND

Systemic inflammatory response is significant prognostic indicator in patients with various diseases. The relationship between prognostic scoring systems based on the modified Glasgow Prognostic Score (mGPS) and achalasia in patients treated with laparoscopic Heller‑myotomy with Dor‑fundoplication (LHD) remains uninvestigated. This study aimed to examine the role of mGPS in patients with achalasia.

METHODS

457 patients with achalasia who underwent LHD as the primary surgery between September 2005 and December 2020 were included. We divided patients into the mGPS 0 and mGPS 1 or 2 groups and compared the patients' background, pathophysiology, symptoms, surgical outcomes, and postoperative course.

RESULTS

mGPS was 0 in 379 patients and 1 or 2 in 78 patients. Preoperative vomiting and pneumonia were more common in patients with mGPS of 1 or 2. There were no differences in surgical outcomes. Postoperative upper gastrointestinal endoscopy revealed that severe esophagitis was more frequently observed in patients with mGPS of 1 or 2 (P < 0.01). The clinical success was 91% and 99% in the mGPS 0 and mGPS 1 or 2 groups, respectively (P < 0.01).

CONCLUSIONS

Although severe reflux esophagitis was more common in patients with achalasia with a high mGPS, good clinical success was obtained regardless of the preoperative mGPS.

Prognostic significance of platelet‑to‑albumin ratio in patients with nasopharyngeal carcinoma receiving concurrent chemoradiotherapy: a retrospective study of 858 cases

BACKGROUND

Despite evidence supporting the high correlation of the novel platelet-to-albumin ratio (PAR) with survival in diverse malignancies, its prognostic relevance in nasopharyngeal carcinoma (NPC) remains underexplored. This study aimed to examine the link between PAR and overall survival (OS) in NPC and to establish a predictive model based on this biomarker.

METHODS

We retrospectively assembled a cohort consisting of 858 NPC patients who underwent concurrent chemoradiotherapy (CCRT). Utilizing the maximally selected log-rank method, we ascertained the optimal cut-off point for the PAR. Subsequently, univariate and multivariate Cox proportional hazards models were employed to discern factors significantly associated with OS and to construct a predictive nomogram. Further, we subjected the nomogram's predictive accuracy to rigorous independent validation.

RESULTS

The discriminative optimal PAR threshold was determined to be 4.47, effectively stratifying NPC patients into two prognostically distinct subgroups (hazard ratio [HR] = 0.53; 95% confidence interval [CI]: 0.28-0.98, P = 0.042). A predictive nomogram was formulated using the results from multivariate analysis, which revealed age greater than 45 years, T stage, N stage, and PAR score as independent predictors of OS. The nomogram demonstrated a commendable predictive capability for OS, with a C-index of 0.69 (95% CI: 0.64-0.75), surpassing the performance of the conventional staging system, which had a C-index of 0.56 (95% CI: 0.65-0.74).

CONCLUSIONS

In the context of NPC patients undergoing CCRT, the novel nutritional-inflammatory biomarker PAR emerges as a promising, cost-efficient, easily accessible, non-invasive, and potentially valuable predictor of prognosis. The predictive efficacy of the nomogram incorporating the PAR score exceeded that of the conventional staging approach, thereby indicating its potential as an enhanced prognostic tool in this clinical setting.

Combination of sarcopenia and systemic inflammation-based markers for predicting the prognosis of patients undergoing pancreaticoduodenectomy for pancreatic cancer

BACKGROUND

This study aimed to evaluate the effects of sarcopenia and inflammation on the prognosis of patients with pancreatic cancer after pancreaticoduodenectomy.

METHODS

Eighty patients who had undergone pancreaticoduodenectomy for pancreatic cancer between July 2010 and December 2023 were included in this study. The psoas muscle index was used to assess sarcopenia. The C-reactive protein-to-albumin ratio, prognostic nutritional index, neutrophil-to-lymphocyte ratio, and platelet-to-lymphocyte ratio were used to calculate the preoperative inflammatory marker levels. The prognostic factors for overall survival were determined using Cox regression analysis.

RESULTS

Twenty-four patients were diagnosed with sarcopenia. Sarcopenia showed a significant association with advanced tumor stage. Univariate analysis revealed a significant reduction in overall survival in patients with a prognostic nutritional index of <45, C-reactive protein-to-albumin ratio of ≥0.047, cancer antigen 19-9 levels of ≥130 U/mL, sarcopenia, lymph node metastasis, and vascular invasion. Multivariate analysis revealed that a C-reactive protein-to-albumin ratio of ≥0.047 (hazards ratio, 3.383; 95% confidence interval: 1.384-8.689; p< 0.001), cancer antigen 19-9 levels of ≥130 U/mL (hazards ratio, 2.720; 95% confidence interval: 1.291-6.060; p = 0.008), sarcopenia (hazards ratio, 3.256; 95% confidence interval: 1.535-7.072; p = 0.002) and vascular invasion (hazards ratio, 2.092; 95% confidence interval: 1.057-4.170; p = 0.034) were independent predictors of overall survival. Overall survival in the sarcopenia and high C-reactive protein-to-albumin ratio groups was significantly poorer than that in the non-sarcopenia and low C-reactive protein-to-albumin ratio and sarcopenia or high C-reactive protein-to-albumin ratio groups.

CONCLUSION

Sarcopenia and a high C-reactive protein-to-albumin ratio are independent prognostic factors in patients with pancreatic cancer after pancreaticoduodenectomy. Thus, sarcopenia may have a better prognostic value when combined with the C-reactive protein-to-albumin ratio.

Prognostic value of a nomogram model for postoperative liver metastasis of colon cancer

BACKGROUND

Colon cancer is one of the most common malignant tumors of the digestive system. Liver metastasis after colon cancer surgery is the primary cause of death in patients with colon cancer.

AIM

To construct a novel nomogram model including various factors to predict liver metastasis after colon cancer surgery.

METHODS

We retrospectively analyzed 242 patients with colon cancer who were admitted and underwent radical resection for colon cancer in Zhejiang Provincial People's Hospital from December 2019 to December 2022. Patients were divided into liver metastasis and non-liver metastasis groups. Sex, age, and other general and clinicopathological data (preoperative blood routine and biochemical test indexes) were compared. The risk factors for liver metastasis were analyzed using single-factor and multifactorial logistic regression. A predictive model was then constructed and evaluated for efficacy.

RESULTS

Systemic inflammatory index (SII), C-reactive protein/albumin ratio (CAR), red blood cell distribution width (RDW), alanine aminotransferase, preoperative carcinoembryonic antigen level, and lymphatic metastasis were different between groups (P < 0.05). SII, CAR, and RDW were risk factors for liver metastasis after colon cancer surgery (P < 0.05). The area under the curve was 0.93 for the column-line diagram prediction model constructed based on these risk factors to distinguish whether liver metastasis occurred postoperatively. The actual curve of the column-line diagram predicting the risk of postoperative liver metastasis was close to the ideal curve, with good agreement. The prediction model curves in the decision curve analysis showed higher net benefits for a larger threshold range than those in extreme cases, indicating that the model is safer.

CONCLUSION

Liver metastases after colorectal cancer surgery could be well predicted by a nomogram based on the SII, CAR, and RDW.

Risk factors of Carbapenem-resistant Enterobacterales intestinal colonization for subsequent infections in hematological patients: a retrospective case-control study

Objective

Infections caused by Carbapenem-resistant Enterobacterales (CRE) have high treatment costs, high mortality and few effective therapeutic agents. This study aimed to determine the risk factors for progression from intestinal colonization to infection in hematological patients and the risk factors for 30-day mortality in infected patients.

Methods

A retrospective case-control study was conducted in the Department of Hematology at Shandong Provincial Hospital affiliated to Shandong First Medical University from April 2018 to April 2022. Patients who developed subsequent infections were identified as the case group by electronic medical record query of patients with a positive rectal screen for CRE colonization, and patients who did not develop subsequent infections were identified as the control group by stratified random sampling. Univariate analysis and logistic regression analysis determined risk factors for developing CRE infection and risk factors for mortality in CRE-infected patients.

Results

Eleven hematological patients in the study developed subsequent infections. The overall 30-day mortality rate for the 44 hematological patients in the case-control study was 11.4% (5/44). Mortality was higher in the case group than in the control group (36.5 vs. 3.0%, P = 0.0026), and septic shock was an independent risk factor for death (P = 0.024). Univariate analysis showed that risk factors for developing infections were non-steroidal immunosuppressants, serum albumin levels, and days of hospitalization. In multivariable logistic regression analysis, immunosuppressants [odds ratio (OR), 19.132; 95% confidence interval (CI), 1.349-271.420; P = 0.029] and serum albumin levels (OR, 0.817; 95% CI, 0.668-0.999; P = 0.049) were independent risk factors for developing infections.

Conclusion

Our findings suggest that septic shock increases mortality in CRE-infected hematological patients. Hematological patients with CRE colonization using immunosuppressive agents and reduced serum albumin are more likely to progress to CRE infection. This study may help clinicians prevent the onset of infection early and take measures to reduce mortality rates.

Prognostic value of the modified Glasgow prognostic score in biliary tract cancer patients: a systematic review and meta-analysis

BACKGROUND

Biliary tract cancer (BTC) is an invasive adenocarcinoma affecting the hepatobiliary system, but high recurrence rates highlight the need for more effective adjuvant approaches. The modified Glasgow prognostic score (mGPS) has been explored as an independent prognostic indicator in patients with BTC. However, consensus on its prognostic value is lacking. This meta-analysis aimed to comprehensively assess the association between mGPS and diverse clinical outcomes in BTC by systematically analyzing relevant studies.

METHODS

A systematic search approach was used to look for eligible papers published until June 2023 in PubMed, Web of Science, and Embase, with a focus on overall survival (OS) and disease-free/recurrence-free survival (DFS/RFS). The prognostic potential of mGPS was assessed using hazard ratios (HRs) with corresponding 95% CIs.

RESULTS

A total of 15 papers comprising 2447 patients were included in this meta-analysis. The results demonstrated that, in patients with BTC, the high mGPS was associated with poorer OS (HR=1.49, 95% CI=1.35-1.65, P<0.001) and DFS/RFS (HR=3.23, 95%CI=1.98-5.26, P=0.193).

CONCLUSION

According to this meta-analysis, our study found that high mGPS was associated with poorer OS and DFS/RFS in patients with BTC.

Prognostic value of diffuse cancer inflammation index (ALI), serum neutrophil/lymphocyte (NLR) and platelet/lymphocyte (PLR) in advanced-stage lung cancer

INTRODUCTION

Lung cancer is the most common type of cancer that causes death worldwide. Systemic inflammation has been shown to play a role in cancer etiopathogenesis and can be activated from oncogenic changes in cancer cells. In our study, the prognostic effects of inflammatory parameters calculated from serum were investigated in lung cancer.

METHOD

One hundred fifteen patients with locally advanced and advanced lung cancer who were diagnosed in our chest diseases clinic between 2013 and 2015 were retrospectively analyzed. The relationship between advanced lung cancer inflammation index (ALI index), serum neutrophil/lymphocyte ratio (NLR), and platelet/lymphocyte ratio (PLR) levels at the time of diagnosis were calculated, and their relationship with overall survival (OS), disease-free survival, and the treatment response and their effect on predicting prognosis were investigated.

FINDINGS

When the ALI value was examined in the group with non-small cell lung, the OS was found to be 9.018 months in the group over 18 years of age and it was 3.78 months in the group below. Low ALI index was significantly associated with short survival ( P <.05). When the NLR values were examined in the entire patient group, OS more than 5 was 5.95 months and less than 9.63 months. A high NLR value was significantly associated with short survival ( P <.05). No significant relationships were detected between PLR and OS. When the determined cut-off values were used, no significant correlation was found between NLR, ALI, and PLR levels and progression-free survival ( P >.05).

CONCLUSION

In our study, it was concluded that elevated NLR levels and low ALI values at the time of diagnosis of advanced-stage lung cancer were associated with poor survival, and those values may be useful in predicting survival and prognosis when the cut-off values were used. These parameters can be useful in routine use because they can be easily calculated without additional costs.

A Joint Model Based on Post-Treatment Longitudinal Prognostic Nutritional Index to Predict Survival in Nasopharyngeal Carcinoma

BACKGROUND

a low PNI in patients with NPC is linked to poor survival, but prior studies have focused on single-timepoint measurements. Our study aims to employ joint modeling to analyze longitudinal PNI data from each routine visit, exploring its relationship with overall survival.

METHODS

In this retrospective study using data from the Chang Gung Research Database (2007-2019), we enrolled patients with NPC undergoing curative treatment. We analyzed the correlation between patient characteristics, including the PNI, and overall survival. A joint model combining a longitudinal sub-model with a time-to-event sub-model was used to further evaluate the prognostic value of longitudinal PNI.

RESULTS

A total of 2332 patient were enrolled for the analysis. Separate survival analyses showed that longitudinal PNI was an independent indicator of a reduced mortality risk (adjusted HR 0.813; 95% CI, 0.805 to 0.821). Joint modeling confirmed longitudinal PNI as a consistent predictor of survival (HR 0.864; 95% CI, 0.850 to 0.879). An ROC analysis revealed that a PNI below 38.1 significantly increased the risk of 90-day mortality, with 90.0% sensitivity and 89.6% specificity.

CONCLUSIONS

Longitudinal PNI data independently predicted the overall survival in patients with NPC, significantly forecasting 90-day survival outcomes. We recommend routine PNI assessments during each clinic visit for these patients.

Association between weight loss and death in patients with malignant melanoma: A retrospective study of 28 cases

Malignant melanoma (MM) is often associated with a poor prognosis due to metastasis and cancer death. The monitoring of prognostic factors is of vital importance, and among these factors, elevated lactate dehydrogenase (LDH) should be closely observed during the disease course. Important factors for predicting the survival of MM patients include tumor thickness, ulceration, the number of lymph node metastases, metastatic lesions, and the sites of metastasis. Weight loss is not generally included in the prognostic factors of MM, but it is monitored in other cancers, such as lung cancer and gastrointestinal cancer. The objective of this study was to investigate the association between weight loss and MM prognosis. Using data from MM patients who had been treated at our institution, we assessed the prognoses of two groups: weight loss of at least 5% body weight or weight loss not exceeding 5% body weight within a 12-month period. As a result, a higher mortality rate was found for the former group. Furthermore, the loss of at least 5% of body weight within a month was found to almost always adversely affect the patient's prognosis. The present study indicates that there may be an association between MM prognosis and weight loss of at least 5% within a year, and body weight could potentially serve as an informative factor for MM survival.

Preoperative C-reactive protein to albumin ratio as a novel prognostic biomarker for the oncological outcomes of radical nephroureterectomy

PURPOSE

This study aimed to evaluate the prognostic impact of the preoperative C-reactive protein to albumin ratio (CAR) on progression-free survival (PFS) and cancer-specific survival (CSS) in patients with upper urinary tract urothelial carcinoma (UTUC) undergoing radical nephroureterectomy (RNU).

METHODS

A retrospective analysis was conducted using data from a single-center nephroureterectomy registry between January 2011 and December 2017. Participants were categorized into high and low CAR groups based on the optimal CAR cut-off value determined using the Youden index. The primary endpoint was PFS, the time from RNU to metastasis or disease recurrence. The secondary endpoint was CSS, the time from RNU to UTUC-related death. Median PFS and CSS were compared between the high and low CAR groups using Kaplan-Meier analysis and log-rank test. Multivariable Cox proportional hazard regression analysis was performed to assess the prognostic significance of CAR, adjusting for known prognostic factors.

RESULTS

We included 491 patients with UTUC in the analysis. The optimal CAR cut-off value was determined to be 0.036, which resulted in classifying 49.3% (242/491) of patients into the high CAR group. The high CAR group had older patients (69.8 vs. 67.4, p-value = 0.01), advanced T and N stages (p-value<0.001), high-grade tumor (p-value = 0.03), and a higher incidence of preoperative hydronephrosis (p-value < 0.01) than the low CAR group. The high CAR group demonstrated significantly inferior median PFS (78.3 vs. 100.3 months, p-value < 0.01) and CSS (73.2 vs. 96.1 months, p-value < 0.01) than the low CAR group. Moreover, high CAR independently increased the risk of disease progression (hazard ratio [HR]: 1.80, 95% confidence interval [CI]: 1.23-2.64, p < 0.01) and UTUC-related mortality (HR: 1.79, 95% CI: 1.15, p < 0.01).

CONCLUSION

Pre-operative CAR is independently associated with poor PFS and CSS in patients with UTUC undergoing RNU. Moreover, CAR may be an independent UTUC prognostic factor, offering a cost-effective and minimally invasive marker. However, further validation through large-scale, multi-center studies is necessary to confirm these findings and determine the optimal CAR cut-off value.

The low cross-sectional muscle index at the third cervical vertebra is a marker for sarcopenia in patients with laryngopharyngeal cancer

BACKGROUND

Muscle loss and sarcopenia play a significant role in head and neck cancer. In this study, the value of C3 cross-sectional skeletal muscle index was investigated to evaluate sarcopenia.

METHODS

Seventy-four patients were included in this retrospective study. Skeletal muscle index (SMI) was calculated using the paracervical muscles at the level of the third cervical vertebra. Survival rates and toxicities were compared.

RESULTS

The 3-year overall survival rates were 33.3% in patients with low SMI (≤44.79) and 63.9% in patients with high SMI (>44.79) (P < 0.01). The 3-year progression-free survival rates were 25.9% in patients with low SMI and 63.2% in patients with high SMI (P < 0.01). Multivariate analyses found that advanced age (>65) was associated with a 2.9-fold increased risk of death and low SMI was associated with a 3.9-fold increased risk of death.

CONCLUSION

Low SMI is associated with prolonged treatment time, increased toxicity, and decreased survival.

Clinical role of pretreatment albumin-to-alkaline phosphatase ratio in lung cancer: a meta-analysis

The association between pretreatment albumin-to-alkaline phosphatase ratio (AAPR) and clinicopathological parameters and prognosis in lung cancer is unclear. The study aimed to identify the clinical role of pretreatment AAPR among lung cancer patients. Several databases were searched for relevant studies. The primary outcome and secondary outcome were long-term survival including the overall survival (OS) and progression-free survival (PFS) and clinicopathological characteristics, respectively. The hazard ratios (HRs) and relative risks (RRs) with 95% confidence intervals (CIs) were combined. A total of 11 publications involving 10,589 participants were included in this meta-analysis. The pooled results manifested that a lower pretreatment AAPR predicted poorer OS (HR = 0.65, 95% CI 0.59-0.71, P < 0.001) and PFS (HR = 0.68, 95% CI 0.59-0.78, P < 0.001). Furthermore, subgroup analysis for the OS and PFS based on the pathological type and treatment showed similar results and pretreatment AAPR was significantly associated with worse prognosis. Besides, pretreatment AAPR was significantly associated with male (RR = 1.08, 95% CI 1.03-1.13, P < 0.001), poor differentiation (RR = 1.33, 95% CI 1.03-1.73, P = 0.029), advanced T stage (RR = 1.25, 95% CI 1.03-1.52, P = 0.026), N stage (RR = 1.34, 95% CI 1.15-1.55, P < 0.001) and TNM stage (RR = 1.14, 95% CI 1.06-1.223, P < 0.001). Therefore, pretreatment AAPR is significantly related to prognosis and tumor stage in lung cancer and patients with a lower pretreatment AAPR are more likely to experience poor survival and advanced tumor stage.

Rad51 and Systemic Inflammatory Indicators as Novel Prognostic Markers in Esophageal Squamous Cell Carcinoma

BACKGROUND

RAD51 is a central protein involved in homologous recombination, which has been linked to cancer development and progression. systemic inflammatory indicator markers such as neutrophil-to-lymphocyte ratio and lymphocyte-to-monocyte ratio have also been implicated in cancer. However, the relationship between Rad51 and these inflammatory markers in esophageal cancer patients undergoing esophagectomy is not yet understood.

METHODS

We retrospectively observed 320 esophageal cancer patients who underwent esophagectomy. We collected clinical characteristics, postoperative complications, and survival analysis data and analyzed the relationship between Rad51 expression, inflammatory markers, and prognosis.

RESULTS

We found significant linear relationships among the inflammatory markers. There were also close relationships between Rad51 expression and neutrophil-to-lymphocyte ratio or C-reactive protein. Patients with low lymphocyte percentage were more likely to have low Rad51 expression (P = .026), high C-reactive protein (P = .007), and high neutrophil-to-lymphocyte ratio (P = .006). Low lymphocyte-to-monocyte ratio was associated with poor overall survival and was an independent prognostic factor (HR = 2.214; 95% confidence interval: 1.044-4.695, P = .038). In patients without lymph node metastases, low albumin (HR= 0.131; 95% confidence interval: 0.025-0.687, P = .016), high neutrophil-to-lymphocyte ratio (HR = 0.002; 95% confidence interval: 0.000-0.221, P = .009), and high Rad51 expression (HR = 14.394; 95% confidence interval: 2.217-97.402, P = .006) were associated with poor overall survival.

CONCLUSIONS

Our study found a close correlation between elevated Rad51 expression and inflammatory markers. High Rad51 expression, high neutrophil-to-lymphocyte ratio, and low lymphocyte-to-monocyte ratio are associated with lower survival rates. The combined assessment of Rad51 and inflammatory markers can be useful for preoperative assessment and prognostic evaluation in esophageal squamous cell carcinoma patients.

The prognostic value of the preoperative albumin/globulin and monocyte ratio in resected early-stage non-small cell lung cancer

OBJECTIVE

This study investigated the prognostic value of the preoperative albumin/globulin to monocyte ratio (AGMR) in patients with resected non-small cell lung cancer (NSCLC).

METHODS

The study retrospectively enrolled patients with resected NSCLC from the Department of Thoracic Surgery, China-Japan Union Hospital of Jilin University from January 2016 to December 2017. Baseline demographic and clinicopathological data were collected. The preoperative AGMR was calculated. Propensity score matching (PSM) analysis was applied. The receiver operating characteristic curve was used to determine the optimal AGMR cut-off value. The Kaplan-Meier method was used to calculate the overall survival (OS) and disease-free survival (DFS). The Cox proportional hazards regression model was used to evaluate the prognostic value of the AGMR.

RESULTS

A total of 305 NSCLC patients were included. The optimal AGMR value was 2.80. Before PSM. The high AGMR (>2.80) group had a significantly longer OS (41.34 + 11.32 vs. 32.03 + 17.01 months; P < 0.01) and DFS (39.00 + 14.49 vs. 28.78 + 19.13 months; P < 0.01) compared with the low AGMR (≤2.80) group. Multivariate analyses showed that AGMR (P < 0.01) in addition to sex (P < 0.05), body mass index (P < 0.01), history of respiratory diseases (P < 0.01), lymph node metastasis (P < 0.01), and tumor size (P < 0.01) were associated with OS and DFS. After PSM, AGMR remained as an independent prognostic factor for OS (hazard ratio [HR] 2.572, 95% confidence interval [CI]: 1.470-4.502; P = 0.001) and DFS (HR 2.110, 95% CI: 1.228-3.626; P = 0.007).

CONCLUSION

The preoperative AGMR is a potential prognostic indicator for OS and DFS in resected early-stage NSCLC.

Development and validation of a nomogram based on preoperative variables for predicting recurrence-free survival in stage IA lung adenocarcinoma

BACKGROUND

This study aimed to establish a nomogram for predicting risk of recurrence and provide a model for decision-making between lobectomy and sublobar resection in patients with stage IA lung adenocarcinoma.

METHODS

Patients diagnosed with stage IA lung adenocarcinoma (LUAD) between December 2010 and October 2018 from Cancer Hospital Chinese Academy of Medical Sciences were included. Patients were randomly assigned to training and validation cohorts, accounting for 70% and 30% of the total cases, respectively. We collected laboratory variables before surgery. Univariate and multivariate analyses were performed in the training cohort to identify variables significantly associated with recurrence-free survival (RFS) which were subsequently used to construct a nomogram. Validation was conducted in both cohorts. A receiver operating characteristic curve was used to determine the optional cutoff values of the scores calculated from the nomogram. Patients were then divided into low- and high-risk groups. Survival was performed to determine if the nomogram could guide the operation method.

RESULTS

A total of 543 patients were included in this study. Gender, albumin level, carcinoembryonic antigen level and cytokeratin-19-fragment level were included in the nomogram. In both cohorts, the nomogram stratified the patients into high- and low-risk groups in terms of RFS. In particular, there was a significant difference in RFS between lobectomy and sublobar resection in the high-risk group.

CONCLUSIONS

Gender, albumin level, carcinoembryonic antigen level and cytokeratin-19-fragment level are valuable markers in predicting recurrence and can guide surgical practice in patients with stage IA LUAD.

Preoperative albumin-to-globulin ratio and prognostic nutritional index predict the prognosis of colorectal cancer: a retrospective study

The immunonutritional status has important effects on outcomes for cancer patients. Albumin-to-globulin ratio (AGR) and the prognostic nutrition index (PNI) are often used to assess the immunonutritional status of cancer patients. However, the clinical significance of these factors in colorectal cancer (CRC) remains unclear. We aimed to evaluate the clinical significance of the AGR and PNI in CRC. We reviewed the clinical data of 511 patients with CRC in two hospitals. Data from one institution was used as the training cohort. The optimal cutoff values for AGR and PNI in the training cohort were 1.4 and 48.65, respectively. Patients in both the low AGR and low PNI groups had poor overall survival (OS) and progression-free survival (PFS), while those in the low AGR-low PNI group had the lowest OS and PFS. Multivariate analysis revealed that preoperative AGR, preoperative PNI, gross type, and TNM stage were independent prognostic factors influencing OS in patients with CRC. Preoperative AGR, preoperative PNI, and TNM stage were independently associated with PFS in patients with CRC. According to the results of multivariate analysis in the training cohort, we developed the nomograms for OS and PFS and performed internal and external validation, which showed good prediction ability of the nomograms. In conclusion, preoperative AGR and PNI can be used as effective indicators to predict survival for patients with CRC. AGR and PNI may help develop effective adjuvant-therapy schedules.

Compromised Nutritional Status as a Risk Factor for the Incidence of Nosocomial Infections

Background Poor nutritional status may lead to longer hospital stays, increased mortality and morbidity, increased cost, and higher suffering. Nosocomial infections (NI) are a global health concern, and several risk factors are associated with their higher incidence. This study aimed to reveal that compromised nutritional status is one of the risk factors for developing NIs. Methodology The study was conducted in a tertiary care hospital in Pune, India. This was a prospective cohort study with a sample size of 200 hospitalized participants. Data collection was based on standard tools and structured forms which had two parts. In the first part, the assessment of nutritional status was done for which patients were categorized into two groups, namely, well-nourished and undernourished. Additionally, biochemical parameters (serum albumin) were also assessed. The second part included a follow-up of participants to evaluate the development of NIs including their laboratory investigation. Results were analyzed statistically using R software. Results Among 200 participants, 60 were female, of whom 15% developed NIs. Of the 140 males, 8% had NIs. Among 200 participants, 101 (51%) were well-nourished, of whom two (2%) developed NIs. Of the 99 (49%) undernourished participants, 18 (18%) had NIs. Those who were undernourished (univariate relative risk = 6.10, 95% confidence interval) were more prone to developing NIs compared to the well-nourished group. Conclusions NIs are widespread globally but are less studied and given less emphasis in developing countries. This study reports various types of NIs along with their incidence in well-nourished and undernourished groups. The incidence of NI observed in this study may reflect the higher severity of illness, age, poor nutritional status, and longer hospital stays. Identifying risk factors that can contribute to developing NI may help in their prevention by maximizing patient safety.

Diagnostic value of CA125, HE4, and systemic immune-inflammation index in the preoperative investigation of ovarian masses

This study aimed to ascertain the diagnostic accuracy of CA125, HE4, systemic immune-inflammation index (SII), fibrinogen-to-albumin ratio (FAR), prognostic nutritional index (PNI), and their combination for ovarian cancer (OC) to discover an optimal combined diagnostic index for early diagnosis of OC. A thorough investigation was conducted to ascertain the correlation between these markers and the pathological characteristics of OC, thereby providing a foundation for early identification and treatment of this disorder. One hundred seventy patients with documented OC and benign ovarian tumors (BOTs) treated at Hebei General Hospital between January 2019 and December 2022 were included in this retrospective study. Data analysis was conducted using IBM SPSS Statistics version V26.0, MedCalc Statistical Software version 19.4.0, and the R Environment for Statistical Computing software (R Foundation for Statistical Computing). Isolated CA125 showed the best application value for differentiating benign ovarian tumors from OC when the defined variables were compared separately. The combination of CA125, HE4, FAR, SII, and PNI displayed a greater area under the operating characteristic curve curve than any one of them or other combinations of the 5 variables. Compared to CA125 alone, the combination of CA125, HE4, FAR, SII, and PNI showed a slight gain in sensitivity (83.91%), negative predictive value (83.91%), accuracy (85.88%), and a decrease in negative likelihood ratio (0.180%). Higher preoperative CA125, HE4, SII, and FAR levels, and lower PNI levels predicted a higher probability of advanced OC progression and lymph node metastasis. FAR has better application value than other inflammation-related markers (PNI and SII). This study suggests that preoperative serum SII, PNI, and FAR may be clinically valuable markers in patients with OC. FAR has better application value than other inflammation-related markers (PNI and SII). As we delve deeper into the inflammatory mechanisms associated with tumors, we may discover more effective combinations of tumor and inflammatory biomarkers.

Is the Prognostic Nutritional Index a Prognostic Marker for the Survival of Patients with Lymph-Node Positive Stage II-III Gastric Cancer Who Receive Adjuvant Chemotherapy?

PURPOSE

The prognostic nutritional index (PNI), like other systemic inflammatory markers, has been shown to be a prognostic factor in various cancer patients. In this study, we aimed to show whether PNI calculated before adjuvant chemotherapy is a prognostic factor for overall survival (OS) and disease-free survival (DFS) in patients with lymph node-positive stage II-III gastric cancer.

METHODS

The PNI was calculated using the albumin and lymphocyte count. The PNI cut-off value was found to be 39.5. They were divided into two groups as being ≤ 39.5 (PNI low group) and > 39.5 (PNI high group).

RESULTS

Our study included 168 patients with lymph node-positive stage II-III gastric cancer who received adjuvant chemotherapy. Of the patients, 116 (69.0%) were 65 years or younger, and 52 (31.0%) were over 65 years old. Of the patients, 117 (69.6%) were pT3, 51 (30.4%) were pT4. Seventy-three (43.4%) patients had pN1-2 disease and 95 (56.6%) patients had pN3 disease. The number of stage II patients was 73 (43.5%) and the number of stage III patients was 95 (56.5%). There were 73 patients with PNI ≤ 39.5 and 95 patients with PNI > 39.5. The mOS of the patients with low PNI group was 39.5 months, while the OS of the patients with high PNI group was 96.8 months (p = 0.002). In the group of patients with PNI low group, mDFS 24.4 months was significantly higher than those with PNI high group was 50.7 months (p = 0.021). The PNI score was statistically significant in univariate and multivariate analyzes for both DFS and OS.

CONCLUSION

PNI can be used as an independent prognostic factor for both OS and DFS in patients lymph node-positive, stage II-III gastric cancer who will receive adjuvant chemotherapy.

Impact of a novel immune and nutritional score on prognosis in patients with upper urinary tract urothelial carcinoma following radical nephroureterectomy

BACKGROUND

This study aimed to evaluate the clinical significance of a novel immune and nutritional score combining prognostic values of the controlling nutritional status (CONUT) score and prognostic immune and nutritional index (PINI) on long-term outcomes in patients with upper tract urothelial carcinoma (UTUC) after radical nephroureterectomy (RNU).

METHODS

This study analyzed 437 consecutive patients with UTUC treated by RNU. Restricted cubic splines were used to visualize the relation of PINI with Survival in patients with UTUC. The PINI was stratified into low- (1) and high-PINI (0) categories. The CONUT score was divided into three groups: Normal (1), Light (2), and Moderate/severe (3). Subsequently, patients were grouped according to CONUT-PINI score (CPS) (CPS group 1; CPS group 2; CPS group 3; and CPS group 4). Survival curves were plotted using the Kaplan-Meier method and log-rank test. The Cox proportional hazards regression model was used to determine the risk factors associated with overall Survival (OS) and cancer-specific Survival (CSS). By comprising independent prognostic factors, a predictive nomogram was constructed.

RESULTS

PINI and CONUT score were identified as independent prognostic factors for OS and CSS. Kaplan-Meier survival analysis showed that the high CPS group was associated with worse OS and CSS than the low CPS group. Multivariate Cox regression and competing risk analyses showed that CPS, LVI, T stage, margin, and pN were independent factors associated with OS and CSS. Based on these five significant factors, we constructed a prognostic model for predicting clinical outcomes. The receiver operating characteristic curve indicated that the model had excellent predictive abilities for survival. The C-index of this model for OS and CSS were 0.773, and 0.789, respectively. The nomogram for OS and CSS showed good discrimination and calibration. Decision curve analysis (DCA) showed that this nomogram has a higher net benefit.

CONCLUSION

The CPS combined the prognostic capacity of PINI and CONUT score and was able to predict patient outcomes in our cohort of UTUC patients. We have developed a nomogram to facilitate the clinical use of the CPS and provide accurate estimates of survival for individuals.

Prognostic significance of albumin-to-globulin ratio in patients with renal cell carcinoma: a meta-analysis

Background

Whether the albumin-to-globulin ratio (AGR) predicts the prognosis of renal cell carcinoma (RCC) remains controversial. Herein, we performed a meta-analysis to critically evaluate the relationship between the AGR and RCC prognosis, as well as the association between the AGR and the clinicopathological characteristics of RCC.

Methods

The PubMed, Web of Science, Embase, and Cochrane Library databases were thoroughly and comprehensively searched from their inception until 24 June 2023. To determine the predictive significance of the AGR, hazard ratios (HRs) and corresponding 95% confidence intervals (CIs) were calculated from the pooled data. The relationship between the AGR and the clinicopathological features of RCC was evaluated by estimating odds ratios (ORs) and 95% CIs in subgroup analyses.

Results

The meta-analysis included nine articles involving 5,671 RCC cases. A low AGR significantly correlated with worse overall survival (OS) (HR = 1.82, 95% CI = 1.37-2.41, p <0.001) and progression-free survival (PFS) (HR = 2.44, 95% CI = 1.61-3.70, p <0.001). Analysis of the pooled data also revealed significant associations between a low AGR and the following: female sex (OR = 1.48, 95% CI = 1.31-1.67, p <0.001), pT stage T3-T4 (OR = 4.12, 95% CI = 2.93-5.79, p <0.001), pN stage N1 (OR = 3.99, 95% CI = 2.40-6.64, p <0.001), tumor necrosis (OR = 3.83, 95% CI = 2.23-6.59, p <0.001), and Fuhrman grade 3-4 (OR = 1.82, 95% CI = 1.34-2.42, p <0.001). The AGR was not related to histology (OR = 0.83, 95% CI = 0.60-1.15, p = 0.267).

Conclusion

In patients with RCC, a low AGR strongly predicted poor OS and PFS and significantly correlated with clinicopathological features indicative of disease progression.

Preoperative hypoalbuminaemia in liver surgery: an observational study at a university medical centre

OBJECTIVES

Preoperative hypoalbuminaemia is associated with adverse outcome, including increased postoperative mortality in cardiovascular surgery, neurosurgery, trauma and orthopaedic surgery. However, much less is known about the association between preoperative serum albumin and clinical outcomes after liver surgery. In this study, we sought to determine whether hypoalbuminaemia before partial hepatectomy is associated with a worse postoperative outcome.

DESIGN

Observational study.

SETTING

University Medical Centre in Germany.

PARTICIPANTS

We analysed 154 patients enrolled in the perioperative PHYsostigmine prophylaxis for liver resection patients at risk for DELIrium and postOperative cognitive dysfunction (PHYDELIO) trial with a preoperative serum albumin assessment. Hypoalbuminaemia was defined as serum albumin <35 g/L. Subgroups classified as hypoalbuminaemia and non-hypoalbuminaemia consisted of 32 (20.8%) and 122 (79.2%) patients, respectively.

OUTCOME MEASURES

The outcome parameters of interest were postoperative complications according to Clavien (moderate: I, II; major: ≥III), length of intensive care unit (ICU) stay, length of hospital stay and survival rates 1 year after surgery.

RESULTS

Preoperative hypoalbuminaemia was associated with the occurrence of major postoperative complications (OR 3.051 (95% CI 1.197 to 7.775); p=0.019) after adjusting for age, sex, randomisation, American Society of Anesthesiologists physical status, preoperative diagnosis and Child-Pugh class. Both ICU and hospital lengths of stay were significantly prolonged in patients with preoperative hypoalbuminaemia (OR 2.573 (95% CI 1.015 to 6.524); p=0.047 and OR 1.296 (95% CI 0.254 to 3.009); p=0.012, respectively). One-year survival was comparable between patients with and without hypoalbuminaemia.

CONCLUSIONS

We found that low serum albumin before surgery was associated with a worse short-term outcome after partial hepatectomy, which strengthens the prognostic value of serum albumin in the setting of liver surgery.

Prognostic significance of the preoperative alkaline phosphatase‑to‑albumin ratio in patients with hepatocellular carcinoma after hepatic resection

This study aimed to investigate the prognostic value of the preoperative alkaline phosphatase-to-albumin ratio (APAR) in patients with hepatocellular carcinoma (HCC) who underwent radical hepatectomy. The clinicopathological data from 330 patients was retrospectively analyzed. Receiver operating characteristic curves of APAR for diagnostic tumor recurrence were plotted with a cut-off value of 1.74. A high preoperative APAR value was significantly associated with hepatitis B surface antigen level, tumor diameter, and tumor-node-metastasis stage. The disease-free survival (DFS) and overall survival (OS) of patients with a high preoperative APAR were shorter than those with a low APAR. The independent risk factors for DFS were an APAR ≥1.74, and macrovascular invasion or tumor thrombus. The independent risk factors for OS were an APAR ≥1.74, existing clinical symptoms, α-fetoprotein level ≥20 ng/ml, macrovascular invasion or tumor thrombus, and family history of cancer. In conclusion, a preoperative APAR (≥1.74) is an independent risk factor influencing the poor prognosis of patients with HCC after curative hepatectomy, and patients with such a result should be closely monitored.
