Albumin to globulin ratio (AGR) in systemic lupus erythematosus: correlation with disease activity.

To investigate the role of albumin-to-globulin ratio (AGR) in systemic lupus erythematosus (SLE) and its relationship with disease activity. This retrospective study consecutively selected patients with SLE and healthy controls. Patients were divided into three groups according to the SLE Disease Activity Index 2000 (SLEDAI-2K): group 1 (mild disease activity, SLEDAI-2K ≤ 6), group 2 (moderate disease activity, SLEDAI-2K 7-12) and group 3 (severe disease activity, SLEDAI-2K > 12). Predictors of SLE disease activity were analysed by ordinal logistical regression. A total of 101 Chinese patients with SLE and 75 healthy Chinese controls were included. Patients with SLE had lower AGR values than healthy individuals, and group 3 patients with SLE displayed lower AGR values than those in group 1, but similar values to group 2. AGR was inversely correlated with SLEDAI-2K (r = -0.543). Ordinal logistic regression analysis showed that lower AGR (β = -1.319) and lower complement C4 (β = -1.073) were independent risk factors for SLE disease activity. AGR was decreased in patients with SLE and may be utilized as a useful inflammatory biomarker for monitoring SLE disease activity.

The Albumin to Globulin Ratio Performs Well for Diagnosing Periprosthetic Joint Infection: A Single-Center Retrospective Study

BackgroundAccurate diagnosis of the periprosthetic joint infection (PJI) remains a challenge for surgeons. The purpose of this study was to assess the value of albumin to globulin ratio (AGR) and globulin (GLB) for diagnosing PJI. MethodsA total of 182 patients undergoing revision after arthroplasty were included and divided into 2 groups, 61 in knee group (PJI: 38; non-PJI: 23) and 121 in hip group (PJI: 26; non-PJI: 95). We used receiver operating characteristic curves to determine the diagnostic value of AGR, GLB, inflammatory markers (erythrocyte sedimentation rate [ESR] and C-reactive protein [CRP]). ResultsThe receiver operating characteristic curves showed the areas under the curve of AGR, GLB, ESR, and CRP in the knee group were 0.940, 0.928, 0.867, and 0.848, respectively, and they were 0.855, 0.831, 0.886, and 0.912 in the hip group. The optimal predictive cut-off values for AGR in knee and hip groups were 1.375 and 1.295, respectively. The sensitivity and specificity of AGR, respectively, were 94.7% and 87.0% (knee group) and 84.6% and 75.8% (hip group) for diagnosing PJI. The sensitivity of “AGR or ESR” and specificity of “AGR and GLB” in the knee group were 99.6% and 98.9%, respectively. ConclusionFor knee or hip groups, the AGR exhibits good value for the diagnosis of PJI comparable with ESR and CRP. The AGR and GLB, together with CRP and ESR, should be used as the preferred indicators for diagnosing PJI. The “AGR or ESR” and “AGR and GLB” in the knee group have an excellent diagnostic value in sensitivity and specificity, respectively.

Low Pretreatment Albumin-to-Globulin Ratios Predict Poor Survival Outcomes in Patients with Head and Neck Cancer: A Systematic Review and Meta-analysis.

Background: Studies have indicated that a low albumin-to-globulin ratio (AGR) before treatment is linked to poor prognosis of many cancers, but the prognostic impact of AGR remains controversial in head and neck cancer (HNC). This meta-analysis examined the prognostic value of AGR in HNC. Methods: We systematically searched the Embase, PubMed, and Cochrane library for relevant articles from inception to July 22, 2022. Studies conducted from 2000 to 2022 exploring the prognostic value of AGR in HNC were retrieved. We employed a random-effects model and calculated pooled hazard ratios (HRs) with corresponding 95% confidence intervals (CIs) to examine the associations of AGR with survival outcome. Results: Our analysis included nine studies involving 3211 patients with HNC. The pooled results revealed significant associations between low pretreatment AGRs and poor disease-free survival (HR = 1.97, 95% CI 1.58-2.45, p < 0.001), distant metastasis-free survival (HR = 1.64, 95% CI 1.25-2.16, p < 0.001), overall survival (HR = 2.18, 95% CI 1.65-2.88, p < 0.001), T3-T4 status (OR = 2.22, 95% CI 1.43-3.44, p < 0.001), stage III-IV disease (OR = 2.62, 95% CI 1.62-4.23, p < 0.001), and lymph node metastasis (OR = 1.95, 95% CI 1.29-2.82, p = 0.001) in patients with HNC. Conclusion: AGR can serve as a prognostic biomarker in managing HNC, and a low pretreatment AGR is strongly associated with adverse survival outcomes and advanced cancer status. Additional large-scale prospective trials must be conducted to assess the validity of our findings.

The potential performance of serum albumin to globulin ratio, albumin and globulin in the diagnosis of periprosthetic joint infection and prediction of reinfection following reimplantation

BackgroundThis study was conducted to evaluate the performance of serum albumin (ALB), globulin (GLO), and albumin to globulin ratio (AGR) in the diagnosis of PJI and prediction of reinfection following reimplantation in PJI patients who underwent two-stage revision.MethodsWe perform a retrospective data collection on identified patients who underwent revision arthroplasties in our institution from January 2010 to January 2020. A total of 241 patients were stratified into: group A (PJI), group B (aseptic loosening). Fifty-five patients who underwent two-stage revision in group A were assigned to group C. Group C was stratified into subgroup 1 (reinfection) and subgroup 2 (non-reinfection). Receiver operating characteristic curves were used to evaluate the utility of serum markers for diagnosing PJI and predicting reinfection following reimplantation.ResultsIn the diagnosis of PJI, there were significant differences in the levels of ALB, GLO, and AGR between groups A and group B (P < 0.05). The AUC value of serum AGR (0.851) was similar to ESR (0.841) and CRP (0.866) (all p > 0.05). The AUC values of serum ALB and GLO were 0.757 and 0.753, respectively. As for predicting reinfection following reimplantation, the serum ALB in the non-reinfection group was higher than that in the reinfection group (p = 0.041). The AUC value of serum ALB was 0.7.ConclusionAGR was promising adjunct marker for the diagnosis of PJI, similar to CRP and ESR. ALB and GLO have an acceptable value for the diagnosis of PJI. ALB may be expected to be a kind of effective marker for predicting reinfection following reimplantation.

AB0528 CORRELATION BETWEEN ALBUMIN TO GLOBULIN RATIO AND DISEASE ACTIVITY IN SYSTEMIC LUPUS ERYTHEMATOSUS

BackgroundNeutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) have been reported as useful inflammatory biomarkers associated with the disease activity of systemic lupus erythematosus (SLE). Recently, the albumin to globulin ratio (AGR) has emerged as a potential indicator to predict the prognosis of some cancers. However, whether AGR can predict the disease activity of SLE has been rarely investigated.ObjectivesThis study was to explore the relation between AGR and SLE Disease Activity Index 2000 (SLEDAI-2K) in patients with SLE.MethodsThis retrospective study enrolled 101 SLE patients and 75 age- and gender-matched healthy individuals. According to the SLEDAI-2K score, SLE patients were classified into Group 1 with a score of 9 or lower (patients with mild disease activity, N = 60) and Group 2 with a score &gt; 9 (patients with moderate to severe disease activity, N = 41). Albumin, globulin, NLR, PLR, monocyte to lymphocyte ratio (MLR), AGR, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), complement 3 (C3), complement 4 (C4), SLEDAI-2K and other clinical data were collected. Receiver operation characteristic (ROC) curves were conducted to discriminate SLE patients from healthy controls and SLE patients with different disease activity. Correlations between the inflammatory markers and SLEDAI-2K were checked. The prognostic value of AGR in the SLE disease activity was tested by logistical regression analyses.ResultsAlbumin and AGR in SLE patients were lower compared to those of the healthy controls (P &lt; 0.05), while NLR, PLR, MLR, globulin and CRP were higher (P &lt; 0.05). Patients in Group 2 had lower levels of albumin, AGR, C3 and C4 than those in Group 1 (P &lt; 0.05), NLR and PLR were higher (P &lt; 0.05), while MLR (P = 0.198), globulin (P = 0.704), CRP (P = 0.224) and ESR (P = 0.135) displayed no significant differences. The ROC curves for differentiating SLE patients from healthy individuals showed that the area under curve (AUC) of AGR (0.812, 95%CI: 0.750 - 0.874) and albumin (0.840, 95%CI: 0.782 - 0.898) were higher than NLR (0.786, 95%CI: 0.719 - 0.853), PLR (0.708, 95%CI: 0.629 - 0.786), MLR (0.776, 95%CI: 0.708 - 0.845) and globulin (0.630, 95%CI: 0.548 - 0.713). Similarly, the ROC curves for predicting the disease activity of SLE patients displayed that the AUC of AGR (0.779, 95%CI: 0.689 - 0.870) and albumin (0.827, 95%CI: 0.746 - 0.909) were also higher than NLR (0.644, 95%CI: 0.534 - 0.753), PLR (0.672, 95%CI: 0.565 - 0.780), MLR (0.583, 95%CI: 0.466 - 0.701), globulin (0.521, 95%CI: 0.403 - 0.639), CRP (0.567, 95%CI: 0.452 - 0.683), ESR (0.589, 95%CI: 0.475 - 0.703), C3 (0.709, 95%CI: 0.603 - 0.815) and C4 (0.655, 95%CI: 0.542 - 0.768). AGR was negatively correlated with SLEDAI-2K (r = -0.543, P &lt; 0.001) in SLE patients. Logistical regression analyses showed that AGR (OR = 13.047, 95%CI: 3.407 - 49.966, P &lt; 0.001) was an inverse predictor for SLE disease activity, yielding a highest hazard than other inflammatory parameters.ConclusionAGR was significantly decreased in SLE patients compared with healthy subjects and negatively associated with the disease activity of SLE. AGR might be a potential indicator for evaluating inflammation in patients with SLE.

Clinical impact of pretreatment albumin-globulin ratio in patients with colorectal cancer: A meta-analysis.

Background:Accumulating evidence have revealed that pretreatment albumin to globulin ratio (AGR) may be a predictor of prognosis among patients with colorectal cancer (CRC). However, these findings are inconsistent. The aim of the present study was to investigate the prognostic value of pretreatment AGR in CRC.Methods:A systematic meta-analysis was conducted by searching MEDLINE, EMBASE, and Cochrane Library databases.Results:A total of 9 studies with 7939 patients were finally included. Low pretreatment AGR was associated with worse overall survival (pooled hazard ratio [HR]: 2.07, 95% CI: 1.60–2.67, P < .001) and disease-free survival/progress-free survival (pooled hazard ratio [HR]: 2.10, 95% confidence interval [CI]: 1.34–3.31, P = .001). Subgroup analyses revealed that the pooled correlation did not alter these results. Moreover, low pretreatment AGR were associated with elderly patients, tumor diameter (≥50 mm), tumor node metastasis stage (III–IV), depth of tumor (T3–4), and CA19-9 (>37 U/mL).Conclusion:The present meta-analysis suggests that low pretreatment AGR was associated with advanced clinicopathological features and worse prognosis, suggesting AGR is a useful prognostic biomarker for CRC patients.

Prognostic value of preoperative albumin to globulin ratio in patients treated with salvage radical prostatectomy for radiation recurrent prostate cancer.

Background Serum albumin-to-globulin ratio (AGR) has been shown to be associated with poor prognosis in different malignancies. In this study we aimed to evaluate the predictive value of preoperative AGR for oncological outcomes in patients with radiation recurrent prostate cancer (PCa) treated with salvage radical prostatectomy (SRP). Methods A retrospective review of 214 consecutive patients with radiation-recurrent PCa who underwent SRP at five referral centers. Levels of albumin and globulin were obtained before SRP and used to calculate the preoperative AGR level. The optimal cut off value of preoperative AGR was 1.4. Univariable and multivariable Cox regression analyses were performed. Results Overall 89 (41.6%) patients had a low preoperative AGR. Low serum AGR was associated with biochemical recurrence (BCR) in univariable Cox regression analysis (HR 1.60, 95%CI 1.06-2.43, P=0.026). When adjusted for the effects of established preoperative and postoperative clinicopathologic confounders in different multivariable Cox regression models, this association did not retain its statistical significance. Moreover, preoperative AGR was not associated with metastasis free survival (P= 0.21), overall survival (P= 0.91) or cancer specific survival (P=0.61). Conclusions In patients with radiation recurrent PCa undergoing SRP, low preoperative AGR was associated with the risk of BCR only in univariable analysis. There was no association with metastasis or survival outcomes. Further studies are needed to evaluate this biomarker in the setting of primary PCa and to identify the patients most likely to benefit from a local therapy.

Significance of albumin to globulin ratio as a predictor of febrile urinary tract infection after ureteroscopic lithotripsy.

BackgroundWe aimed to analyze the effectiveness of albumin to globulin ratio (AGR) in predicting postoperative febrile urinary tract infection (fUTI) after ureteroscopic lithotripsy (URS) and retrograde intrarenal surgery (RIRS).MethodsFrom January 2013 to May 2018, 332 patients underwent URS and RIRS. The rate of postoperative fUTI and risk factors for postoperative fUTI were analyzed using logistic regression. Patients were divided into postoperative fUTI and non-postoperative fUTI (non-fUTI) groups. AGR with other demographic and perioperative data were compared between the two groups to predict the development of fUTI after URS.ResultsOf the 332 patients, postoperative fUTI occurred in 41 (12.3%). Preoperative pyuria, microscopic hematuria, diabetes mellitus, hypoalbuminemia, and hyperglobulinemia were more prevalent in the fUTI group. Patients in the fUTI group had larger stone size, lower preoperative AGR, longer operation time, and longer preoperative antibiotic coverage period. In a multivariable logistic analysis, preoperative pyuria, AGR, and stone size were independently correlated with postoperative fUTI (p<0.001, p=0.008, and p=0.041, respectively). Receiver operating curve analysis showed that the cutoff value of AGR that could predict a high risk of fUTI after URS was 1.437 (sensitivity, 77.3%; specificity, 76.9%), while the cutoff value of stone size was 8.5 mm (sensitivity, 55.3%; specificity, 44.7%).ConclusionThis study demonstrated that preoperative pyuria, AGR, and stone size can serve as prognostic factors for predicting fUTI after URS.

Impact of albumin to globulin ratio on survival outcomes of patients with metastatic renal cell carcinoma.

The albumin to globulin ratio (AGR) has been demonstrated to be associated with survival outcomes in various tumor types. However, the prognostic value of AGR in patients with metastatic renal carcinoma (mRCC) remains unclear. Therefore, this study aimed to investigate the impact of AGR values in predicting overall survival (OS) of patients with mRCC treated with targeted therapy. A total of 163 patients with mRCC treated with targeted therapy between 2008 and 2019 were enrolled. The AGR value was measured as AGR: albumin/(total protein-albumin). The Kaplan-Meier method with long-rank testing and Cox proportional hazard models were used to estimate the correlation of AGR with OS. The receiver operating characteristic curve analysis showed that the optimal cut-off value of AGR in predicting OS was 1.11 with a sensitivity of 37.25% and specificity of 85.25% (area under curve, 0.62; 95% confidence interval [CI], 0.54-0.69; p=0.005). OS was significantly higher in patients with AGR>1.11 than in those with AGR≤1.11 (36.2 vs. 12.4 months; p<0.001). After adjustment for the number of covariates, multivariate Cox regression analysis identified a high AGR as an independent indicator of better OS (hazard ratio, 0.476; 95% CI, 0.304-0.745; p=0.001). Our results suggested that AGR value, which is an easily obtainable and cost-effective marker in routine biochemistry testing, could function as an independent predictor of OS in patients with mRCC treated with targeted therapy.

Decrease of Preoperative Serum Albumin-to-Globulin Ratio as a Prognostic Indicator after Radical Cystectomy in Patients with Urothelial Bladder Cancer.

This study aims to evaluate whether preoperative serum albumin-to-globulin ratio (AGR) could predict the prognosis of patients with urothelial bladder cancer (UBC) after radical cystectomy (RC). A total of 176 patients with UBC who underwent RC in a tertiary hospital between 2008 and 2019 were retrospectively analyzed. The AGR was calculated as albumin/(total protein - albumin). In addition, the AGR was divided into two groups for the time-dependent receiver operating characteristic curve (ROC) analysis. Survival was estimated using the Kaplan-Meier analysis and compared using the log-rank test. Cox proportional- hazards models were used for multivariate survival analysis. The best cutoff AGR value for metastasis prediction was 1.32 based on the ROC curve analysis. Patients who had lower pretreatment AGR (<1.32) values composed the low-AGR group (n = 57; 32.4%). On the other hand, the remaining patients (n = 119; 67.6%) composed the high-AGR group. The patients in the low-AGR group had more advanced stage tumors compared with the patients in the high-AGR group. The Kaplan-Meier curves revealed that the patients in the low-AGR group had significantly lower rates of metastasis-free survival (MFS) and cancer-specific survival (CSS). The multivariate Cox regression analysis showed that preoperative AGR was an independent prognostic factor for MFS and CSS. In this single-institution retrospective study, lower preoperative AGR values demonstrated a poor prognostic effect on MFS and CSS in patients with UBC who underwent RC.

Relation Between Globulin, Fibrinogen, and Albumin With the Presence and Severity of Coronary Artery Disease.

The albumin to globulin ratio (AGR) is used as a prognostic marker in acute ischemic cardiovascular events. We investigated whether serum AGR, fibrinogen, and fibrinogen to albumin ratio (FAR) are related to the presence and severity of coronary artery disease (CAD). Patients who underwent coronary angiography procedures were analyzed retrospectively. The severity of CAD was assessed by the Gensini score. The study population (3031 patients; 1071 females and 1960 males) was divided into 3 tertiles based on AGR values. Gensini score, lipid levels, diabetes mellitus (DM), hypertension (HT), age, and fibrinogen level were higher in the low AGR group. Pearson correlation analysis showed that AGR (r = -0.068, P < .001) was negatively and fibrinogen (r = 0.187, P < .001) was positively correlated with the Gensini score. Male gender, HT, smoking, DM, age, high triglyceride (TG) level, low-density lipoprotein cholesterol (LDL-C) >160 mg/dL, estimated glomerular filtration rate (eGFR) <60 mL/min, and fibrinogen level >3.5 g/L were independent predictors of CAD. Male gender, age, eGFR, DM, LDL-C, TG, and FAR had an independent positive relation to the Gensini score. In conclusion, similar to traditional risk factors, plasma fibrinogen and albumin levels showed a close relation with the presence and severity of CAD.

The role of preoperative albumin to globulin ratio in predicting prognosis in testicular cancer patients

Introduction and objectivesIn recent years, the incidence of testicular cancer has increased, but mortality rates have decreased thanks to the improvements in treatment. Although primary tumor characteristics and serum tumor markers are associated with metastasis and relapse, their predictive value is not reliable. Therefore, there is a need for new biomarkers that predict prognosis. In this study, we aimed to investigate the role of preoperative albumin to globulin ratio (AGR) in predicting retroperitoneal lymph node (RPLN) involvement, distant metastasis and prognosis in testicular cancer. Material and methodsWe retrospectively analyzed the medical records of all patients that underwent radical inguinal orchiectomy at our hospital between 2007 and 2018. AGR was calculated using the equation: AGR = serum albumin/(serum total protein-serum albumin). The predictive value of AGR for RPLN involvement and distant metastasis was evaluated using receiver operating characteristic analysis and its prognostic value was evaluated using Kaplan-Meier survival analysis. ResultsA total of 115 patients with a mean age of 33.4 ± 7.7 years were included the study. In multivariate analysis, AGR less than 1.47 and the presence of lymphovascular invasion were detected as the factors predicting RPLN involvement and distant metastasis. The AGR of patients who had died was significantly lower than AGR of those who were alive, 1 ± 0.2 versus 1.6 ± 0.3 (P = .001). In Kaplan-Meier survival analysis, the mean survival of patients with higher AGR (>1.47) was found longer than patients with lower AGR (<1.47). ConclusionsPreoperative AGR is a biomarker that may be used in predicting RPLN involvement, distant metastasis and prognosis in testicular cancer.

Prognostic values of preoperative albumin to globulin ratio for predicting clinical outcome in patients with high-grade gliomas

Background: Gliomas was the most common primary central nervous system tumors which have an increased morbidity in recent years. And the clinical prognosis of high-grade gliomas (HGG, WHO grade III to IV) was most with an average survival rate of only dozens of months. Many researchers concluded that the level of preoperative albumin-to-globulin ratio (AGR) could predict the clinical outcome of patients with solid malignant tumors. Methods: Two hundred and thirty-two cases of patients who were diagnosed HGG by pathology were enrolled in the study. The relevant data of the cohort included sex, age, preoperative Karnofsky performance score (KPS), extent of resection, albumin count and globulin count, isocitrate dehydrogenase (IDH) and survival time were collected. The survival rate was obtained by using the Kaplan-Meier method. The cut-off value of AGR was determined by X-tile software. Univariate survival analysis was performed by the log-rank method. Proportional hazards model (Cox model) was performed for multivariate analysis. Results: The optimal cut-off value of AGR was 1.32. Results showed that the preoperative AGR was correlated with clinical prognosis of patients with HGG, and the survival time of the patients with high AGR (AGR >1.32) was significantly longer. Moreover, the prognosis of patients with high AGR was better in IDH wild-type HGG. Conclusions: Preoperative AGR might predict the clinical prognosis of patients with HGG.

Prognostic Values of Systemic Inflammation Response (SIR) Parameters in Resectable Cervical Cancer.

Background:Cervical carcinoma is the leading cause of cancer mortality in women. C-reactive protein (CRP), albumin (ALB), globulin (GLB), lactate dehydrogenase (LDH), and albumin-to-globulin ratio (AGR) are indicators of systemic inflammation response correlated with tumor outcomes.Methods:This study recruited 110 patients with cervical cancer. The patients were divided into 2 groups according to pretreatment median values of CRP, ALB, GLB, LDH, and AGR. The post/preradiotherapy or post/pretreatment ratios were defined as rates of pretreatment CRP, ALB, GLB, LDH, and AGR values and the corresponding ones obtained after radiotherapy or whole treatment.Results:Higher pretreatment CRP or LDH levels were correlated with worse progression-free survival (PFS) and overall survival (OS). Increased post/preradiotherapy CRP ratio was correlated with worse PFS and OS, increased post/preradiotherapy LDH ratio was correlated with worse PFS. Increased post/pretreatment CRP ratio was correlated with worse PFS and OS, not-increased post/pretreatment AGR ratio was correlated with worse OS. Cox regression analysis model indicated that, moderately or poorly of differentiation, higher pretreatment CRP or LDH levels were independently associated with worse PFS, higher pretreatment CRP or LDH levels and increased post/pretreatment CRP ratio were independently associated with worse OS.Conclusion:CRP, LDH, or AGR are correlated with outcomes of resectable cervical cancer.

Prognostic impact of pretreatment albumin to globulin ratio in patients with diffuse large B-cell lymphoma treated with R-CHOP

ObjectiveWe evaluated the clinical implications of the albumin to globulin ratio (AGR) in patients with diffuse large B-cell lymphoma (DLBCL) treated with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP). MethodsData of 232 patients with DLBCL treated with first-line R-CHOP from 2004 to 2017 were reviewed retrospectively. Patients with AGR values ≥1.22 and <1.22 were assigned to the high and low AGR groups, respectively. Treatment response, treatment-related toxicity, and survival were compared according to the AGR. ResultsThe complete response rate was significantly lower in the low AGR group than in the high AGR group (59.1% vs. 81.3%; p < 0.001). Treatment-related mortality was also more frequent in the low AGR group than in the high AGR group (14.0% vs. 4.3%; p = 0.009). The low AGR group (median overall survival [OS] = 26.87 months; 95% confidence interval [CI] = 4.19–49.55) showed a significant decrease in OS compared to the high AGR group (median OS = 148.83 months; 95% CI = 76.26–221.41; p < 0.001). Progression-free survival (PFS) also decreased significantly in the low AGR group (median PFS = 14.29 months; 95% CI = 2.58–26.01) compared to the high AGR group (median PFS = 148.83 months; 95% CI = 76.21–221.45; p < 0.001). In a multivariate analysis, low AGR was an independent poor prognostic factor for OS and PFS. ConclusionsPretreatment AGR was useful for predicting treatment response, treatment-related toxicity, and prognosis in patients with DLBCL treated with R-CHOP. Further large prospective studies will be necessary to validate our findings.

The pretreatment albumin to globulin ratio as a significant predictor in patients with diffuse large B cell lymphoma

BackgroundThe pretreatment albumin to globulin ratio (AGR) has been used to predict survival in several types of tumors. However, whether AGR can predict outcomes in patients with diffuse large B-cell lymphoma (DLBCL) remains unclear. We evaluated the prognosis value of AGR in DLBCL patients. MethodsWe retrospectively analyzed the available serum biochemical results of 335 patients with newly diagnosed DLBCL before treatment. The AGR was calculated as: albumin (g/L)/globulin. X-tile program was used to generate an optimal cut-off value of 1.3 for AGR. And all patients were respectively divided into the low AGR and high AGR groups according to the cut-off value. ResultsThe low AGR group displayed more adverse clinical chacteristics, including old age, sex (female), increased β2-microglobulinpoor (β2-MG), increased lactate dehydrogenase (LDH), B symptoms, poor performance status (PS), advanced stage, number of extranodal sites ≥ 2 and higher International Prognostic Index (IPI). AGR was negatively correlated with age, IPI score, ECOG score, Ann Arbor stage, B symptoms, β2-MG, LDH, and extranodal involvement, while positively correlated with gender. Patients with a low AGR presented with significantly poorer overall survival (OS, P = .001). Multivariate analysis further demonstrated that a low AGR was an independent adverse predictor for OS (HR = 0.613; 95% CI = 0.412–0.910, P = .015). In addition, AGR distinguished patients with different prognosis in stage III-IV and the non-germinal center B cell-like lymphoma (non-GCB) groups, a low AGR was also significantly associated with poor OS in 2 groups. ConclusionPretreatment AGR was a simple and effective clinical marker of survival in patients with DLBCL, and may had an additional prognostic value based on Ann Arbor stage and cell of origin for DLBCL.

Prognostic importance of the albumin to globulin ratio in metastatic gastric cancer patients

Aim: The aim of this study was to evaluate the prognostic importance of the albumin to globulin ratio (AGR) in terms of overall survival (OS) and progression free survival (PFS) in metastatic gastric cancer patients.Methods: The patients diagnosed with metastatic gastric cancer between 2009 and April 2016 at the hospital have been studied retrospectively. The clinicopathological characteristics, laboratory, and treatment parameters have been assessed. AGR value has been calculated using the following formula (AGR = serum albumin/total protein − serum albumin).Results: In total, 251 patients were included in the study population. The median value of AGR was 1.206 (range = 0.460–3.130), and the cut-off value was set as 1.20. Based on the cut-off value, 126 patients were categorized in the low AGR group, while the remaining 125 patients were categorized in the high AGR group. ECOG (Eastern Cooperative Oncology Group) performance scores, CEA levels, CA19-9 levels, hemoglobin levels, lactate dehydrogenase levels, and liver metastasis ratios varied significantly between the low and high AGR groups (p < .05). The Kaplan-Meier curve has shown that, compared to the low AGR group, the high AGR group has better OS (12.2 vs 9.3 months, p = .002) and better PFS (8.0 vs 5.7 months, p < .001) rates. The univariate and multivariate analyses also proved that low AGR is an independent bad risk factor in metastatic gastric cancer patients, both in terms of OS (p = .019, Hazard Ratio (HR) = 1.380, 95% Confidence Interval (CI) = 1.055–1.805) and PFS (p = .002, HR = 1.514, 95% CI = 1.164–1.968).Conclusion: In metastatic gastric cancer patients, AGR is an independent prognostic factor for OS and PFS. Thus, in this patient group, the low cost albumin and globulin which can be measured with routine clinical practice may be used as an appropriate prognostic tool.
