The predictive value of γ-glutamyl transferase to serum albumin ratio in hepatocellular carcinoma patients after liver transplantation. Front Med (Lausanne) 2024; 11:1380750. [PMID: 38799149 PMCID: PMC11122022 DOI: 10.3389/fmed.2024.1380750] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2024] [Accepted: 04/08/2024] [Indexed: 05/29/2024] Open
Abstract
Background Elevated preoperative γ-glutamyl transferase (GGT) levels or reduced serum albumin levels have been established as negative prognostic factors for patients with hepatocellular carcinoma (HCC) and various other tumors. Nonetheless, the prognostic significance of the GGT to serum albumin ratio (GAR) in liver transplantation (LT) therapy for HCC is still not well-defined. Methods A retrospective analysis was conducted on the clinical data of 141 HCC patients who underwent LT at Shulan (Hangzhou) Hospital from June 2017 to November 2020. Using the receiver operating characteristic (ROC) curve, the optimal GAR cutoff value to predict outcomes following LT was assessed. Univariate and multivariate Cox proportional hazards regression analyses were used to identify independent risk factors associated with both overall survival (OS) and recurrence-free survival (RFS). Results A GAR value of 2.04 was identified as the optimal cutoff for predicting both OS and RFS, with a sensitivity of 63.2% and a specificity of 74.8%. Among these patients, 80 (56.7%) and 90 (63.8%) met the Milan and the University of California San Francisco (UCSF) criteria, respectively. Univariate Cox regression analysis showed that microvascular invasion (MVI), maximum tumor size (>5 cm), total tumor size (>8 cm), liver cirrhosis, TNM stage (III), and GAR (≥2.04) were significantly associated with both postoperative OS and RFS in patients with HCC (all p < 0.05). Multivariate Cox regression analysis indicated that GAR (≥2.04) was independently linked with RFS and OS. Conclusion Pre-transplant GAR ≥2.04 is an independent correlate of prognosis and survival outcomes after LT for HCC and can be used as a prognostic indicator for both mortality and tumor recurrence following LT.

Int J Cancer 2021; 150:472-481. [PMID: 34536292 DOI: 10.1002/ijc.33813] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2021] [Revised: 08/13/2021] [Accepted: 09/09/2021] [Indexed: 12/19/2022]
Abstract
Programmed death 1 (PD-1) inhibitors are widely used for treatment of hepatocellular carcinoma (HCC). Hypothyroidism is commonly associated with this therapy, although the mechanism underlying this complication and effects on patient prognosis remain unclear. We retrospectively analysed the data of patients with HCC who received anti-PD-1 therapy at Tongji Hospital, Tongji Medical College of Huazhong University of Science and Technology between January 2018 and May 2020. Based on thyroid function evaluation, patients were categorised into hypothyroidism group and nonhypothyroidism group. Follow-up was completed on February 28, 2021. The primary endpoint of our study was progression free survival (PFS). The study included 74 patients, and the disease control rate was higher in hypothyroidism group (62.7%, 27/43) than in nonhypothyroidism group (36.4%, 11/31) (P = .020). The PFS was longer in hypothyroidism group (7.44 months) than in nonhypothyroidism group (5.68 months) (P = .006). Additionally, the PFS of patients with hypothyroidism before immunotherapy (6.27 months) was also longer than that in nonhypothyroidism group (5.68 months), although the difference was statistically nonsignificant (P = .527). Cox regression analysis showed that the hazard ratios of hypothyroidism, Child-Pugh grade B at initial admission and serum gamma-glutamyl transferase levels >71 U/L before immunotherapy were 0.404 (95% confidence interval [CI]: 0.207-0.791, P = .008), 2.753 (95%CI: 1.127-6.455, P = .026) and 2.469 (95%CI: 1.155-5.277, P = .020), respectively. Hypothyroidism was associated with prognosis in patients with HCC treated with PD-1 inhibitors, and prognosis was more favourable in patients with hypothyroidism than in those without hypothyroidism. Hypothyroidism and the Child-Pugh grade at initial admission were independently associated with patient prognosis.

Non-Alcoholic Fatty Liver Disease Modifies Serum Gamma-Glutamyl Transferase in Cigarette Smokers. J Clin Med Res 2020; 12:472-482. [PMID: 32849935 PMCID: PMC7430878 DOI: 10.14740/jocmr3932] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2019] [Accepted: 01/22/2020] [Indexed: 11/11/2022] Open
Abstract
Background Serum gamma-glutamyl transferase (GGT) is a marker of oxidative stress, associated with increased cardiovascular (CV) risk. The impact of smoking on oxidative stress may be aggravated in individuals with non-alcoholic fatty liver disease (NAFLD). We aimed to ascertain the association of smoking on GGT levels in the presence or absence of NAFLD. Methods We evaluated 6,354 healthy subjects (43 ± 10 years, 79% males) without clinical cardiovascular disease (CVD) undergoing an employer-sponsored physical between December 2008 and December 2010. NAFLD was diagnosed by ultrasound and participants were categorized as current or non-smokers by self report. A multivariate linear regression of the cross-sectional association between smoking and GGT was conducted based on NAFLD status. Results The prevalence of NAFLD was 36% (n = 2,299) and 564 (9%) were current smokers. Smokers had significantly higher GGT levels in the presence of NAFLD (P < 0.001). After multivariable adjustment, current smoking was associated with 4.65 IU/L higher GGT level, P < 0.001, compared to non-smokers. When stratified by NAFLD, the magnitude of this association was higher in subjects with NAFLD (β-coefficient: 11.12; 95% confidence interval (CI): 5.76 - 16.48; P < 0.001); however, no such relationship was observed in those without NAFLD (β: -0.02; 95% CI: -3.59, 3.56; P = 0.992). Overall the interaction of NAFLD and smoking with GGT levels as markers of oxidative stress was statistically significant. Conclusions Smoking is independently associated with significantly increased oxidative stress as measured by GGT level. This association demonstrates effect modification by NAFLD status, suggesting that smoking may intensify CV risk in individuals with NAFLD.

Abstract
Background Elevated serum γ-glutamyltransferase (γ-GT) levels are related to an increased cancer risk and worse prognosis in many cancers. We evaluated the effects of γ-GT stratification on the occurrence of macrovascular invasion (MVI) in patients with hepatocellular carcinoma (HCC) who underwent hepatic resection (HR), transcatheter arterial chemoembolization (TACE), or TACE combined with radiofrequency ablation (TACE-RFA). Patients and methods A total of 903 patients with HCC in Barcelona Clinic Liver Cancer Stage A or B were included. Of these patients, 118 underwent HR, 445 underwent TACE-RFA, 256 underwent TACE, and 84 patients received conservative treatment only (control group). γ-GT, albumin, α-fetoprotein, and intervention were selected as significant predictive factors for MVI in 1 year by forward selection. The optimal cutoff value of γ-GT was 39 IU/L according to receiver operating characteristic analysis, with a sensitivity and specificity of 87.0% and 45.6%, respectively. Results The 1-year MVI incidence of patients with HCC in the group with γ-GT ≥39 IU/L was higher than that of the group with γ-GT <39 IU/L treated with HR, TACE-RFA, or TACE (P=0.0166, P=0.0041, and P<0.001, respectively). The MVI rates at 1 year were similar in the group with γ-GT ≥39 IU/L that underwent HR, TACE-RFA, or TACE and the control group (P=0.4402, P=0.2214, and P=0.4159, respectively). Different effects of various treatments with γ-GT <39 IU/L group on the occurrence of MVI are not significant (P=0.5167). However, the incidence of MVI after TACE was significantly higher than that after HR or TACE-RFA in γ-GT ≥39 IU/L group (P=0.0253). Conclusion Baseline serum γ-GT stratification may help select the appropriate treatment to reduce the MVI incidence.

Prognostic value of pretreatment serum alanine aminotransferase/aspartate aminotransferase (ALT/AST) ratio and gamma glutamyltransferase (GGT) in patients with esophageal squamous cell carcinoma. BMC Cancer 2017; 17:544. [PMID: 28806937 PMCID: PMC5556356 DOI: 10.1186/s12885-017-3523-y] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2016] [Accepted: 08/01/2017] [Indexed: 12/25/2022] Open
Abstract
BACKGROUND The levels of liver function tests (LFTs) are often used to assess liver injury and non-liver disease-related mortality. In our study, the relationship between pretreatment serum LFTs and overall survival (OS) was evaluated in esophageal squamous cell carcinoma (ESCC) patients. METHODS Our purpose was to investigate the prognostic value of the preoperative alanine aminotransferase/aspartate aminotransferase (ALT/AST) ratio and gamma glutamyltransferase (GGT) in ESCC patients. A retrospective study was performed in 447 patients with ESCC, and follow-up period was at least 60 months until death. The prognostic significance of serum LFTs were determined by univariate and multivariate Cox hazard models. RESULTS LFTs including ALT, AST, LSR, GGT, TBA and LDH were analyzed. Serum LSR (HR: 0.592, 95% CI = 0.457-0.768, p < 0.001 and GGT (HR: 1.507, 95% CI = 1.163-1.953, p = 0.002) levels were indicated as significant predictors of OS. The 5-year OS among patients with higher LSR levels was longer compared with those patients with decreased LSR levels, not only in the whole cohort but also in the subgroups stratified by pathological stage (T1-T2 subgroup, T3-T4 subgroup, N0 subgroup and M0 subgroup). We also found that patients with a higher GGT might predict worse OS than patients with a normal GGT, not only in the whole cohort but also in the subgroups stratified by pathological stage (T3-T4 subgroup and N1-N2 subgroup). CONCLUSIONS Both increased levels of LSR and decreased levels of GGT might predict shorter overall survival in ESCC patients. Our findings suggest that serum LSR and GGT levels could be used as a key predictor of survival in patients with ESCC.

Elevated Preoperative Serum Gamma-glutamyltranspeptidase Predicts Poor Prognosis for Hepatocellular Carcinoma after Liver Transplantation. Sci Rep 2016; 6:28835. [PMID: 27381639 PMCID: PMC4933871 DOI: 10.1038/srep28835] [Citation(s) in RCA: 31] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2016] [Accepted: 06/09/2016] [Indexed: 02/06/2023] Open
Abstract
Gamma-glutamyltransferase (γ-GGT) is a membrane-bound enzyme that is involved in biotransformation, nucleic acid metabolism, and tumourigenesis. Elevated serum γ-GGT levels are related to an increased cancer risk and worse prognosis in many cancers. In the present study, we evaluated the prognostic value of preoperative serum γ-GGT in patients with hepatocellular carcinoma (HCC) who underwent liver transplantation (LT). A total of 130 HCC patients after LT were included in the study. The optimal cut-off value of γ-GGT was 128U/L by receiver operating characteristic analysis, with a sensitivity and specificity of 60.0% and 72.9%, respectively. Elevated preoperative serum γ-GGT was significantly associated with high alpha-fetoprotein (AFP), large tumor size, and macro- and micro-vascular invasion. The 1-, 3-, 5-year disease-free survival (DFS) and overall survival (OS) rates of HCC patients in the γ-GGT > 128U/L group were poorer than those in the γ-GGT ≤ 128U/L group. Stratification analysis revealed that γ-GGT exhibited a greater predictive value for DFS and OS in HCC patients beyond the Milan criteria and no macro-vascular invasion. In conclusion, elevated preoperative serum γ-GGT was significantly associated with advanced tumor stage and aggressive tumor behaviors, and serum γ-GGT can be considered as a prognostic factor for HCC patients after LT, especially for patients beyond the Milan criteria or without macro-vascular invasion.

Abstract
Elevated serum γ-glutamyltransferase (GGT) is a marker of hepatic injury and is associated with risk of chronic disease. However, the value of GGT as a biomarker for cancer risk remains unclear. Therefore, we evaluated the association of serum GGT with cancer incidence among more than 1.6 million Koreans. We included 1,662,087 Koreans (1,108,121 men and 553,966 women aged 20-95 years) who received health insurance from the National Health Insurance Service and had a biennial medical evaluation between 1995 and 1998. Follow-up was through December 2012. Using Cox proportional hazards models, we adjusted for age, smoking status, alcohol consumption, exercise and body mass index after exclusion of early cases (cancer diagnosis or death within 5 years of starting follow-up) and estimated hazard ratios (HRs) of overall and organ-specific cancer incidence by GGT quintiles. During the 17-year follow-up, 129,087 new cancer cases occurred among the participants. Across levels of GGT, there was a positive gradient of HR and the highest quintile of GGT (≥ 60 IU/L) had the highest HR for all cancers in both men and women. By cancer site, the association was strongest for liver cancer, comparing the highest and lowest strata in men [HR, 6.67; 95% confidence interval (95%CI), 5.88-7.57] and in women (HR, 7.57; 95%CI, 6.41-8.94). Significant associations were also observed for cancers of the esophagus, larynx, stomach, colorectal, bile duct and lung in men and of the bile duct in women. Increased serum GGT level is independently associated with risk of cancer.

Abstract
PURPOSE OF REVIEW To explore the causal relationship between metabolic syndrome, type 2 diabetes and hyperuricemia. RECENT FINDINGS The prevalence of hyperuricemia in male adults with metabolic syndrome was increased and a large difference in prevalence of metabolic syndrome also existed in those with hyperuricemia compared with normouricemia. Even in those with normouricemia, higher serum uric acid levels were associated with metabolic syndrome. Serum uric acid was an independent risk factor for incident diabetes, and evidence showed that the patients with both gout and type 2 diabetes exhibited a mutual inter-dependent effect on higher incidences. Furthermore, obese patients often demonstrated insulin resistance and adipose tissue macrophage with low-grade inflammation, which is suggested to be the major contributor. Although alcohol intake is considered a risk for developing hyperuricemia, moderate alcohol intake showed a lower risk for developing type 2 diabetes and insulin resistance. Hyperinsulinemia reduces renal excretion of uric acid on the proximal tubular of the kidney leading to hyperuricemia, which has deleterious effects on endothelial function and on nitric oxide bioavailability, thus causing hyperinsulinemia. SUMMARY We found evidence to suggest that insulin resistance plays a potentially key role in the causal relationship between metabolic syndrome, type 2 diabetes and hyperuricemia. Furthermore, it is likely that hyperuricemia and insulin resistance share a bidirectional causal effect.

Abstract
BACKGROUND Serum gamma-glutamyltransferase level has attracted considerable attention as a predictor of various conditions, such as cardiovascular disease and cancer. Although the mechanism that links the serum gamma-glutamyltransferase level to these diseases is not fully understood, one explanation is that gamma-glutamyltransferase may be closely related to oxidative stress. We conducted a large cross-sectional study to evaluate the relationship between serum gamma-glutamyltransferase and oxidative stress. METHODS We examined anti-oxidative stress activity and accumulation of oxidative stress in serum obtained from 2907 subjects who underwent a complete health check-up. We used serum total superoxide dismutase activity as an index of anti-oxidative stress activity. Superoxide dismutase is one of the most important intracellular and extracellular defense systems against superoxide, but the relationship between serum superoxide dismutase activity and the serum gamma-glutamyltransferase level is unclear. RESULTS The serum gamma-glutamyltransferase level was negatively correlated with serum superoxide dismutase activity, a correlation that was observed even within the normal range. A subgroup analysis stratified by the amount of alcohol consumed also showed a similar correlation. In contrast, the serum gamma-glutamyltransferase level was positively correlated with serum lipid peroxide level, even in the normal range. Furthermore, an increased serum gamma-glutamyltransferase level was significantly associated with the progression of metabolic syndrome and carotid artery intima-media thickness. CONCLUSIONS The serum gamma-glutamyltransferase level, even in the normal range, was significantly associated with anti-oxidative stress activity, the accumulation of oxidative stress, metabolic syndrome, and atherosclerosis. Measuring the serum gamma-glutamyltransferase level is simple and inexpensive, and this level can be used as a sensitive marker of oxidative stress and metabolic syndrome.

Metabolism 2011; 60:1100-6. [PMID: 21251684 DOI: 10.1016/j.metabol.2010.12.002] [Citation(s) in RCA: 51] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/21/2010] [Revised: 12/03/2010] [Accepted: 12/08/2010] [Indexed: 12/15/2022]
Abstract
Insulin resistance is closely associated with numerous metabolic disorders. Although studies have supported the importance of insulin resistance in carcinogenesis, the existing data have not established its relevance in the context of lung cancer. The aim of the present case-control study was to evaluate the association between insulin resistance and lung cancer after adjusting for possible confounders. Homeostasis model assessment of insulin resistance (HOMA-IR) and serum leptin and adiponectin levels were determined in 81 lung cancer cases and 162 age- and sex-matched controls; anthropometric and lifestyle variables were recorded. Mean HOMA-IR in the cases was more than 2-fold higher compared with the mean value of controls (P < .001). Among controls, HOMA-IR correlated positively with serum leptin (r = 0.16; P = .04), body mass index (r = 0.43; P = .0001), and waist-to-hip ratio (r = 0.21; P = .01) but negatively with serum adiponectin (r = -0.29; P = .0002). As expected, smoking was associated with an approximately 10-fold increase in lung cancer risk in multiple logistic regression models. A positive association between HOMA-IR, treated as continuous variable, and lung cancer (odds ratio [OR] = 1.52, 95% confidence interval [CI]: 1.16-1.99, P = .002, model 1) was demonstrated, which persisted after adjustment for somatometric and lifestyle variables (OR = 2.36, 95% CI: 1.00-5.55, P = .05, model 2). When serum adiponectin was also taken into account, the association seemed fairly robust (OR = 2.58, 95% CI: 1.11-6.01, P = .03, model 3); on the contrary, when serum leptin was added, the association remained positive, but lost its statistical significance (OR = 1.76, 95% CI: 0.78-3.98, P = .17, model 4). In the fully adjusted model, HOMA-IR was still positively, but only marginally, associated with lung cancer risk (OR = 2.02, 95% CI: 0.88-4.65, P = .10, model 5). Insulin resistance may represent a meaningful risk factor for lung cancer.

Abstract
In patients with acute coronary syndrome, gamma-glutamyltransferase activity (GGT) proved to be an independent predictor of the development of major adverse cardiac events at early and long terms. No data are available on GGT in ST-elevation myocardial infarction (STEMI). We assessed, in 337 consecutive STEMI patients without previously known diabetes submitted to mechanical revascularization, the prognostic role of GGT for in-Intensive Cardiac Care Unit mortality, together with the relation(s) between GGT and acute glucose dysmetabolism (admission glycemia, peak glycemia, insulin resistance as indicated by the Homeostatic Model Assessment HOMA index). At logistic regression analysis, GGT was an independent predictor for in-ICU mortality (OR 1.01 (95% CI 1.003-1.013) p = 0.002), when adjusted for BMI and for major bleedings [(OR 1.005 (95% CI 1.001-1.009) p = 0.029]. At linear regression analyses, GGT was significantly correlated with admission glycemia (r = 0.172; p = 0.002), uric acid (r = 0.146; p = 0.011), insulin (r = 0.171; p = 0.002) and age (r = -0.129; p = 0.020). We document that in STEMI patients without previously known diabetes submitted to mechanical revascularization, GGT values are an independent predictor of early mortality. The significant correlation between GGT and acute glucose dysmetabolism (as indicated by admission glycemia and insulin-resistance) can account, at least in part, for the prognostic role of GGT.
