Abstract
Oxidative stress and apoptosis are involved in the pathogenesis of obesity-related diseases. This observational study investigates the antioxidant and apoptotic markers response to an oral glucose tolerance test (OGTT) in a population of overweight children and adolescents, with normal (NGT) or impaired glucose tolerance (IGT). Glucose, insulin, and C-peptide concentrations, as well as oxidative stress (SOD, GPx3) and apoptotic markers (Apo1fas, cck18), were determined at T = 0, 30, 60, 90, 120, and 180 min after glucose intake during OGTT. The lipid profile, thyroid function, insulin-like growth factor1, leptin, ghrelin, and adiponectin were also measured at baseline. The 45 participants, with a mean age of 12.15 (±2.3) years old, were divided into two subcategories: those with NGΤ (n = 31) and those with IGT (n = 14). The area under the curve (AUC) of glucose, insulin, and C-peptide was greater in children with IGT; however, only glucose differences were statistically significant. SOD and GPx3 levels were higher at all time points in the IGT children. Apo1fas and cck18 levels were higher in the NGT children at most time points, whereas Adiponectin was lower in the IGT group. Glucose increased during an OGTT accompanied by a simultaneous increase in antioxidant factors, which may reflect a compensatory mechanism against the impending increase in oxidative stress in children with IGT.

Hepatocyte-derived biomarkers predict liver-related events at 2 years in Child-Pugh class A alcohol-related cirrhosis. J Hepatol 2023; 79:910-923. [PMID: 37302582 DOI: 10.1016/j.jhep.2023.05.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/20/2022] [Revised: 04/25/2023] [Accepted: 05/21/2023] [Indexed: 06/13/2023]
Abstract
BACKGROUND & AIMS In patients with compensated alcohol-related cirrhosis, reliable prognostic biomarkers are lacking. Keratin-18 and hepatocyte-derived large extracellular vesicle (lEV) concentrations reflect disease activity, but their ability to predict liver-related events is unknown. METHODS We measured plasma keratin-18 and hepatocyte lEV concentrations in 500 patients with Child-Pugh class A alcohol-related cirrhosis. The ability of these hepatocyte-derived biomarkers, alone or combined with model for end-stage liver disease (MELD) and FibroTest scores, to predict liver-related events at 2 years was analyzed, taking into account the alcohol consumption at inclusion and during follow-up. RESULTS Keratin-18 and hepatocyte lEV concentrations increased with alcohol consumption. In patients without active alcohol consumption at enrollment (n = 419), keratin-18 concentration predicted liver-related events at 2 years, independently of FibroTest and MELD. Patients with both keratin-18 concentrations >285 U/L and FibroTest >0.74 had a 24% cumulative incidence of liver-related events at 2 years, vs. 5% to 14% in other groups of patients. Similar results were obtained when combining keratin-18 concentrations >285 U/L with MELD >10. In patients with active alcohol consumption at enrollment (n = 81), hepatocyte lEVs predicted liver-related events at 2 years, independently of FibroTest and MELD. Patients with both hepatocyte lEV concentrations >50 U/L and FibroTest >0.74 had a 62% cumulative incidence of liver-related events at 2 years, vs. 8% to 13% in other groups of patients. Combining hepatocyte lEV concentrations >50 U/L with MELD >10 had a lower discriminative ability. Similar results were obtained when using decompensation of cirrhosis, defined according to Baveno VII criteria, as an endpoint. CONCLUSION In patients with Child-Pugh class A alcohol-related cirrhosis, combining hepatocyte-derived biomarkers with FibroTest or MELD scores identifies patients at high risk of liver-related events, and could be used for risk stratification and patient selection in clinical trials. IMPACT AND IMPLICATIONS In patients with compensated alcohol-related cirrhosis, reliable predictors of outcome are lacking. In patients with Child-Pugh class A alcohol-related cirrhosis, combining hepatocyte-derived biomarkers (keratin-18 and hepatocyte-large extracellular vesicles) with FibroTest or MELD scores identifies those at high risk of liver-related events at 2 years. The identified patients at high risk of liver-related events are the target-of-choice population for intensive surveillance (e.g., referral to tertiary care centers; intensive control of risk factors) and inclusion in clinical trials.

Abstract
Background Fragmented cytokeratin 18 (fCK18) is released from damaged hepatocytes undergoing apoptosis and is recognized as a liver condition biomarker. We have developed a highly sensitive serum fCK18 CLEIA and reported that serum levels of this caspase-derived protein were significantly associated with hepatocyte ballooning, thus assisting in the accurate diagnosis of nonalcoholic steatohepatitis (NASH). We aim to investigate serum fCK18 levels in a variety of chronic liver diseases and to explore its potential as a prognostic marker of survival in hepatocellular carcinoma (HCC) patients. Methods Serum fCK18 levels were measured using a highly sensitive CLEIA in 497 chronic liver disease patients (297 outpatients and 200 hospitalized with HCC). Results In 497 chronic liver disease patients, serum fCK18 levels were significantly correlated with overall liver condition, including ALT, FIB-4 index and albumin-bilirubin (ALBI) score and were significantly increased in patients with HCC. In 200 HCC patients, serum fCK18 levels were significantly correlated with alpha-fetoprotein (AFP) and des-gamma-carboxy prothrombin (DCP), and were significantly associated with HCC stage, whereas FIB-4 index and ALBI score were not changed based on HCC stage. The Survival group had significantly lower levels of serum fCK18, AFP, DCP, FIB-4 index and ALBI score. A ROC analysis yield area under the curve (AUC) value of 0.728 for serum fCK18 is a significantly high value when compared to AUC measurements for other factors. Notably, AUROC values for serum fCK18 levels were constant in the short- and long-term by time-dependent ROC analysis for the prediction of HCC patient survival. HCC patients with serum fCK18 measured at < 1.15 ng/mL, AFP < 7.7 ng/mL, DCP < 133 mAU/mL, ALBI score < -2.97 or FIB-4 index < 6.4 had significantly longer rates of survival when compared to patients with values exceeding these thresholds. Serum fCK18 (HR, 3.5; P < 0.0001), DCP (HR, 3.2; P < 0.0001) and Barcelona Clinic Liver Cancer (BCLC) (HR, 2.4; P = 0.001) values were independent predictors of patient survival. [Conclusion] Serum fCK18 levels reflect overall liver function, the level of liver fibrosis and the progression of HCC, and are a potential predictor of survival in HCC patients.

Abstract
Systemic inflammation is a stage-independent marker of poor prognosis in colorectal cancer (CRC), activated in a complex, multifactorial process. It has been proposed that one of the main factors driving systemic inflammation may be tumor necrosis. Keratin 18 (KRT18) fragments are released from dead cells and their serum levels are markers for apoptotic and necrotic cell death. In CRC, high KRT18 levels associate with advanced disease, but their relationship with tumor necrosis and systemic inflammation is unknown. In this study, serum total soluble KRT18 (tKRT18) and apoptosis-related, caspase-cleaved fragment (aKRT18) levels were measured preoperatively from 328 CRC patients, and their difference was calculated to assess necrosis related KRT18 (nKRT18) levels. The relationships of these markers with tumor necrosis, clinicopathologic features, systemic inflammation markers (C-reactive protein, albumin, and 13 cytokines), and survival were analyzed. High serum tKRT18, aKRT18, and nKRT18 levels showed association with a higher extent of tumor necrosis, distant metastasis, and increased levels of several markers of systemic inflammation, including CXCL8. High serum tKRT18 (multivariable HR 1.94, 95% CI 1.28-2.95, p = .002) and nKRT18 (multivariable HR 1.87, 95% CI 1.24-2.82, p = .003) levels were associated with poor overall survival independent of potential confounding factors. Our results show that tumor necrosis in CRC contributes to serum levels of KRT18 fragments, and both necrosis and KRT18 levels associate with systemic inflammation. Moreover, we show that serum tKRT18 and nKRT18 levels have independent prognostic value in CRC. Our observations confirm the link between cell death and systemic inflammation.

The roles of M30 and M65 in the assessment of treatment response and prognosis in patients with non-small cell lung cancer, who receive neoadjuvant treatment. Contemp Oncol (Pozn) 2020; 23:208-213.

Abstract
Aim of the study To investigate the efficacy of evaluating prognosis and response to lung cancer treatment using M30 and M65 antigens, which are indicators of necrosis. Material and methods Forty-eightpatients with lung cancer, who were planned to receive neoadjuvant chemotherapy, and 38 healthy volunteers were enrolled in the study. Using M30 and M65 levels, cytokeratin 18 levels were measured twice: before and 48 hours after the first chemotherapy treatment. Apoptotic and total necrosis levels were determined by measuring the M65 and M30 levels. Results The M30 and M65 antigen levels in the patient group were significantly higher than in the control group (p< 0.001). The M30 and M65 antigen levels were significantly higher 48 hours after the chemotherapy compared with before the chemotherapy (p< 0.001). There were no significant differences in M65 levels between patients who responded to treatment and patients who progressed. The M30 levels increased significantly in patients with disease progression (p= 0.694 and p = 0.024, respectively). No significant differences in serum M30 and M65 antigen levels were found when compared between the surviving and deceased patients (p = 0.126 and p = 0.340, respectively). Conclusions A significant increase was detected in serum M30 and M65 levels in patients with lung cancer. There was a greater increase in serum M30 levels in patients who did not respond to the chemotherapy. This result gives rise to the thought that evaluating apoptosis and total necrosis through M30 and M65 measurements alone only in patients receiving neoadjuvant chemotherapy would be insufficient for specifying the effectiveness of the treatment.

Abstract
Background: Gastrointestinal cancer is one of the most common neoplasms. Cytokeratin 18(CK18) is widely expressed in many different organs and cancers. Emerging data suggested conflicting results about the role of CK18 during carcinogenesis. The aim of this study is to systematically review the prognostic value of circulating CK18 (M65) and caspase-Cleaved CK18 (M30) in digestive cancers. Materials and Methods: We searched major database for manuscripts reporting the effect of pretreatment CK18 on survival of digestive cancer patients. Revman5.3 and R were the software used for analysis. Pooled multivariable-adjusted hazard ratios (HR) for overall survival (OS) were calculated in all patients and many different subgroup analyses by stratifying on tumor type, metastasis stage, and ethnicity. Results: 11 original studies were included for analysis. A low level of M30 and M65 were shown to be a protective factor for all cancer patients (HR 0.49, 95%CI 0.33-0.73, P=0.0003; HR 0.48, 95% CI 0.32-0.70, P =0.0001, respectively). The low M30 remained to be a protective factor for metastasized cancer patients while M65 had no statistically significant correlation with prognosis. Conclusions: Non-invasive total and cleaved CK18 level detection by ELISA could be potentially a useful predictor of prognosis of digestive cancer patients. Further studies are warranted to investigate the molecular mechanisms of CK18.

Abstract
Cytokeratin 18 (CK18), one of the major components of intermediate filaments (IF) in simple epithelial cells, undergoes caspase-mediated cleavage upon epithelial cell necrosis and apoptosis. CK18 has been used as a biomarker of several cancers and has been reported to be dysregulated in cervical cancers. The effects of dysregulated expression of CK18 at a molecular level are, however, unclear. In the present study, the function of CK18 in HeLa cells, a cell line derived from a cervical cancer cells, was investigated using shRNA knockdown. Reduced levels of CK18 led to a significant decrease in cell apoptosis, compared with control cells. Notably, RNA-seq analysis of the transcriptomes of HeLa cells, with or without CK18 knockdown, revealed that genes in the NF-κB pathway, and certain apoptosis pathways, were under global transcriptional and alternative splicing regulation. Quantitative RT-PCR confirmed the CK18-regulated transcription of apoptotic genes FAS and FADD, as well as immune genes CXCL2 and CD79B, in addition to alternative splicing of FAS and CTNNB1. Western blot analysis further revealed that CK18 knockdown led to reduced expression of CASP8. In conclusion, the present study indicated that CK18 played a role in apoptosis, which may be mediated via a feed-back regulation loop and may involve regulation of transcription and alternative splicing of a number of genes in apoptotic pathways.

Lorente L. New prognostic biomarkers of mortality in patients undergoing liver transplantation for hepatocellular carcinoma. World J Gastroenterol 2018; 24:4230-4242. [PMID: 30310256 PMCID: PMC6175764 DOI: 10.3748/wjg.v24.i37.4230] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/24/2018] [Revised: 08/18/2018] [Accepted: 08/24/2018] [Indexed: 02/06/2023] Open
Abstract
The outcome prediction of hepatocellular carcinoma (HCC) patients undergoing liver transplantation (LT) was classically established using various macromorphological factors and serum alpha-fetoprotein levels prior to LT. However, other biomarkers have recently been reported to be associated with the prognosis of HCC patients undergoing to LT. This review summarizes clinical data on these new biomarkers. High blood levels of malondialdehyde, total antioxidant capacity, caspase-cleaved cytokeratin-18, soluble CD40 ligand, substance P, C-reactive protein, and vascular endothelial growth factor, increased neutrophil to lymphocyte ratio and platelet to lymphocyte ratio in blood, high peripheral blood expression of human telomerase reverse transcriptase messenger ribonucleic acid, and high HCC expression of dickkopf-1 have recently been associated with decreased survival rates. In addition, high blood levels of des-gamma-carboxy prothrombin, and high HCC expression of glypican-3, E-cadherin and beta-catenin have been associated with increased HCC recurrence. Additional research is necessary to establish the prognostic role of these biomarkers in HCC prior to LT. Furthermore, some of these biomarkers are also interesting because their potential modulation could help to create new research lines for improving the outcomes of those patients.

Prognostic Value of Serum Caspase-Cleaved Cytokeratin-18 Levels before Liver Transplantation for One-Year Survival of Patients with Hepatocellular Carcinoma. Int J Mol Sci 2016; 17:ijms17091524. [PMID: 27618033 PMCID: PMC5037799 DOI: 10.3390/ijms17091524] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2016] [Revised: 09/01/2016] [Accepted: 09/05/2016] [Indexed: 12/30/2022] Open
Abstract
Cytokeratin (CK)-18 is the major intermediate filament protein in the liver and during hepatocyte apoptosis is cleaved by the action of caspases; the resulting fragments are released into the blood as caspase-cleaved cytokeratin (CCCK)-18. Higher circulating levels of CCCK-18 have been found in patients with hepatocellular carcinoma (HCC) than in healthy controls and than in cirrhotic patients. However, it is unknown whether serum CCCK-18 levels before liver transplantation (LT) in patients with HCC could be used as a prognostic biomarker of one-year survival, and this was the objective of our study with 135 patients. At one year after LT, non-survivors showed higher serum CCCK-18 levels than survivors (p = 0.001). On binary logistic regression analysis, serum CCCK-18 levels >384 U/L were associated with death at one year (odds ratio = 19.801; 95% confidence interval = 5.301–73.972; p < 0.001) after controlling for deceased donor age. The area under the receiver operating characteristic (ROC) curve of serum CCCK-18 levels to predict death at one year was 77% (95% CI = 69%–84%; p < 0.001). The new finding of our study was that serum levels of CCCK-18 before LT in patients with HCC could be used as prognostic biomarker of survival.

Abstract
Background Billions of cells undergo apoptosis each day in the average normal adult. The ability to readily assess the degree of apoptosis in human diseases is hampered by the lack of sensitive and specific serum biomarkers of apoptosis. Fortilin is a novel prosurvival molecule that protects cells against various noxious stimuli. While fortilin is secreted into the extracellular space under certain conditions, the relationship between the serum concentration of fortilin and the presence and extent of apoptosis in vivo remains unknown. Methods & results Using a newly developed fortilin ELISA system, we show here that fortilin exists in the normal human and mouse circulation. We further demonstrate that fortilin serum levels are significantly elevated in patients with solid cancer, in response to anti-cancer chemo- or radiation therapy. The elevation of fortilin serum levels is more robust and sensitive than that of such previously-reported serum biomarkers of apoptosis as fragmented cytokeratin-18, cytochrome c, and nucleosomal DNA. In addition, targeted apoptotic liver damage induced by Jo2 anti-Fas (CD95) antibody consistently and significantly increased serum fortilin levels in C57BL/6J mice. Finally, when challenged by anti-human-Fas IgM antibody, Jurkat leukemic T cells apoptosed and released fortilin into the medium before plasma membrane integrity was compromised. Conclusions Taken together, these data suggest that serum fortilin levels reflect the degree and extent of apoptosis occurring in vivo. General significance Fortilin is a viable serum biomarker of in vivo apoptosis and can be utilized to noninvasively assess the status of in vivo apoptosis in humans. Ultra-sensitive fortilin ELISA has been developed. Fortilin circulates in blood. Fortilin serum levels become highly elevated after apoptosis-inducing therapy. Fortilin is more robust and sensitive than other serum apoptosis markers. Fortilin is actively secreted before plasma membrane becomes disrupted. Fortilin is an excellent serum biomarker of in vivo apoptosis.

Abstract
M30 and M65 are relatively new assays that detect different circulating forms of the epithelial cell structural protein cytokeratin18. The objective of this study was to determine the clinical significance of the serum levels of M30 and M65 in patients with breast cancer. A total of 80 patients with a pathologically confirmed diagnosis of breast cancer were enrolled into the study. Serum M30 and M65 concentrations were determined by the solid-phase sandwich ELISA method. Serum samples were obtained on first admission before any type of treatment. The median age at diagnosis was 52 years, range 30 to 81 years. The baseline serum M30 and M65 levels in patients with metastatic disease were significantly higher than those in the non-metastatic patients (P=0.017 and P=0.003, respectively). Moreover, serum M65 level was also elevated in patients with large tumor size (P=0.02). No correlation was found between these serum assay levels and response to chemotherapy (P>0.05). However, the significant relationship was found between the serum levels of M30 and M65 (rs=0.96, P<0.001). Neither serum M30 nor serum M65 had significantly effect on survival (P=0.50, and P=0.52, respectively). In conclusion, although both serum M30 and M65 levels are elevated in metastatic disease, no predictive and prognostic roles on survival were found in patients with breast cancer.

Abstract
M30 and M65 are circulating fragments of cytokeratin 18 released during apoptotic cell death and regarded as markers of cell death in patients with various tumor types. Our aim was to investigate the clinical and prognostic significance of the serum M30 and M65 concentrations in patients with advanced nasopharyngeal carcinoma. Thirty-two patients with nasopharyngeal cancer and 32 control subjects were investigated. Serum samples were obtained on first admission before any treatment was initiated. Serum M30 and M65 concentrations were measured by quantitative enzyme-linked immunosorbent assay. Median serum M30 (181.5 vs. 45.5 U/L, p < 0.001) and M65 (384.2 vs. 179.1 U/L, p < 0.001) concentrations were significantly higher in patients with advanced nasopharyngeal carcinomas than in controls. receiver operating characteristic (ROC) analysis showed that a cutoff for M30 of 225 U/L had a sensitivity of 62.5% and a specificity of 73.9% (area under the curve (AUC) = 0.592, 95% confidence interval (CI) 35.3-83.2, p = 0.44), while a cutoff for M65 of 423.4 U/L had a sensitivity of 75.1% and a specificity of 65.6% (AUC = 0.562, 95 % CI 36.0-76.5, p = 0.60). However, serum M30 and M65 were not important prognostic factors for progression-free survival. There were no statistically significant correlations between serum M30 and M65 concentrations and clinicodemographical variables. Serum M30 and M65 concentrations were found to have a diagnostic value in nasopharyngeal cancer. However, neither M30 nor M65 serum levels played a prognostic role in the outcome in nasopharyngeal cancer patients.

Abstract
BACKGROUND & AIMS The serum cell death parameters M30 and M65 and the macrophage activation marker sCD163 (soluble CD163) are elevated in patients with acute and chronic liver diseases. However, their diagnostic and prognostic potential in patients with hepatocellular carcinoma (HCC) has not yet been investigated. METHODS Serum levels of M30, M65, and sCD163 were measured in two cohorts of HCC patients and a cohort of cirrhotic patients. The parameters were compared between patients with and without HCC and the overall survival (OS) times according to M30, M65, and sCD163 were assessed. RESULTS M30 and M65 levels were higher in HCC patients than in cirrhotic patients (both p < 0.001). M65 was an independent parameter for non-invasive identification of HCC patients by logistic regression analysis and could supplement AFP (alpha-fetoprotein) and abdominal ultrasound in non-invasive detection of HCC patients. High M65 serum levels as well as high sCD163 concentrations were associated with an impaired prognosis in univariate Cox regression analysis. The sCD163 level was associated with OS independently of the CLIP (Cancer of the Liver Italian Program) score, the BCLC (Barcelona Clinic Liver Cancer) stage, and the CRP (C-reactive protein) level in a multivariate Cox regression model. CONCLUSIONS Serum M65 has the potential as a new diagnostic parameter for HCC and serum sCD163 is a new prognostic parameter in HCC patients.

Abstract
M30 and M65 are relatively new assays that detect different circulating forms of the epithelial cell structural protein cytokeratin 18. This study was carried out to investigate the serum levels of M30 and M65 in patients with melanoma and the relationship with tumor progression and known prognostic parameters. Fifty-two patients with cutaneous melanoma were investigated. Serum samples were obtained on first admission before adjuvant and metastatic treatment were provided and at follow-up. Both serum M30 and M65 levels were determined using an enzyme-linked immunosorbent assay. The median age of patients at diagnosis was 54 years, range 16-88 years; 30 patients were men. Over half of the patients (58%) were in the metastatic stage and most (63%) had M1c. The baseline serum M65 levels were significantly higher in patients with melanoma than in the control group (P < 0.001). For the serum M30 levels, no difference was found (P = 0.76). Both the serum M30 and M65 levels were significantly higher in the patients with leukocytosis (P = 0.02 and 0.007, respectively). In addition, the serum M30 levels were also elevated in young (P = 0.02) and female patients (P = 0.01). A significant relationship was found between the serum levels of M30 and M65 (rs = 0.408, P = 0.003, Spearman's correlation). As expected, distant metastasis (P < 0.001), advanced metastatic stage (M1c) (P = 0.03), elevated erythrocyte sedimentation rate (P = 0.001), higher serum lactate dehydrogenase levels (P < 0.001), and unresponsiveness to chemotherapy (P < 0.001) had worse survival. However, neither serum M30 nor serum M65 had a significantly adverse effect on survival (P = 0.23 and 0.68, respectively). In conclusion, although only serum M65 levels were found to be of diagnostic value, neither M30 nor M65 serum levels played a prognostic role in the outcome in melanoma patients.

Abstract
PURPOSE This study was conducted to determine the clinical significance of serum M30 and M65 in epithelial ovarian cancer (EOC). METHODS A total of 56 patients with EOC and 56 healthy women were included in the study. All of the patients received platinum-based chemotherapy. Pretreatment levels of M30 and M65 were measured using the quantitative ELISA method. RESULTS The median M30 and M65 serum levels were significantly elevated in the EOC patients compared with the healthy controls (96.7 vs. 69.5, p = 0.028 and 436.4 versus 166.3, p < 0.001, respectively). The cut-off value of 423.4 U/L for M65 determined with ROC analysis, predicted progression with 75.1 % sensitivity and 65.6 % specificity (AUC = 0.708, p = 0.008). Patients with higher M65 levels had shorter progression-free survival (PFS) (p = 0.021). Both M30 and M65 serum levels were significantly higher for serous-type histology (p = 0.001 and p < 0.001, respectively). Increased M65 serum levels were associated with advanced disease (p = 0.005) and higher grade (p = 0.005). Moreover, M65 levels were higher for chemotherapy-resistant patients (p = 0.04). Multivariate analysis revealed that an elevated serum M65 level was the only significant independent prognostic factor (p = 0.039, HR 3.792). CONCLUSIONS These results indicated that serum M30 and M65 levels were significantly elevated in patients with EOC compared with healthy women. Particularly, high serum M65 levels were associated with poor prognosis and resistance to platinum-based chemotherapy.

Abstract
M30 and M65 are relatively new assays that detect different circulating forms of the epithelial cell structural protein cytokeratin 18. This study was conducted to investigate the serum levels of M30 and M65 in patients with metastatic pancreatic adenocarcinoma (MPA) and the relationship with tumor progression and known prognostic parameters. Twenty-six patients with MPA were investigated. Serum samples were obtained on first admission before treatment and follow-up. Both serum M30 and M65 levels were determined using enzyme-linked immunosorbent assay. The median age at diagnosis was 59 years, range 32-80 years; 14 patients were men. All patients had metastatic stage, and most (n = 21, 81%) had hepatic metastasis. The baseline levels of both serum M30 and serum M65 were significantly higher in patients with MPA than those in the control group (p < 0.001, for both assays). Serum M65 level was only significantly higher in the patients with elevated serum LDH levels than in others with normal serum LDH levels (p = 0.03). For serum M30 levels, no correlation was found. The significant relationship was found between the serum levels of M30 and M65 (r(s) = 0. 926, n = 26, p < 0.001, Spearman's correlation). The median survival for all patients was 31.7 ± 2.2 weeks (95% CI = 27.31-36.08). Although only the serum LDH level was found to be a significant prognostic factor (p = 0.01), neither serum M30 nor serum M65 had significant effect on survival (p = 0.28 and p = 0.15, respectively). In conclusion, although both serum levels of M30 and M65 assays were found to be of diagnostic value, no predictive and prognostic values were determined in MPA patients.

Abstract
INTRODUCTION Angiogenesis, inflammation and apoptosis have an important place in the carcinogenesis of high-grade gliomas (HGG). We evaluated the postoperative levels and the prognostic importance of tumor necrosis factor-alpha (TNFα), interleukin 6 (IL6), endoglin (CD105), vascular endothelial growth factor (VEGF), M65 and M30 as markers of inflammation, angiogenesis and apoptosis in patients with HGG. METHODS AND RESULTS Postoperative pretreatment sera were collected from 44 newly diagnosed patients with HGG. The control group was also consisted of 44 healthy people. The median age of all patients with HGG was 59 (range: 30-80). Temozolomide concurrent with radiotherapy was given to 37 patients. Thereafter 24 patients received consolidation temozolomide monotherapy. Mean chemotherapy cycle was 4.2. Progression free survival and overall survival were 6 (95% CI; 5.16-6.83) and 16 months (95% CI; 13.07-18.93) respectively in patients treated with concurrent chemoradiotherapy and consolidation chemotherapy. Relative to the control cohort endoglin (p = 0.000) and TNFα (p = 0.000) levels were significantly lower; however VEGF (p = 0.030) levels were higher in the patient group. In contrast, there were no significant change in IL-6 levels and the plasma apoptotic markers M65 (p = 0.085) and M30 (p = 0.292). In separate log rank tests, these biological markers did not correlate with survival. DISCUSSION AND CONCLUSION In HGG, a significant decrease in endoglin and TNFα levels was observed, while VEGF levels were significantly increased postoperatively. However, with the power from this patient population, no correlation with survival was observed.

Abstract
In some studies, the prognostic and predictive significance of M30 and M65 has been reported to detect response to chemotherapy. In the present study, we aimed at determining the changes of serum M30 and M65 values after chemotherapy and the impact of these values on treatment response and progression-free survival (PFS) and overall survival (OS) of patients with advanced gastric cancer. A total of 31 patients with advanced gastric cancer was included. M30 and M65 values were measured by a quantitative enzyme-linked immunosorbent assay (ELISA) method in serum samples before and 48 h after the first chemotherapy cycle. Pre- and postchemotherapy values of M30 and M65 were compared. The difference between the mean values of serum M30 and M65 before and after chemotherapy was calculated and the prognostic significance of changes for survival was evaluated by univariate and multivariate analysis. Logistic regression analysis was performed to predict response to chemotherapy. Serum M30 and M65 levels were found to be increased significantly after chemotherapy (M30, 582.7 ± 111.5 U/l [pre mean] vs. 983.3 ± 214.1 U/l [post mean], p = 0.01; M65, 2,061.7 ± 431.2 U/l [pre mean] vs. 2,646.3 ± 433.1 U/l [post mean], p = 0.003). Means of the differences of M30 and M65 levels before and 48 h after chemotherapy were 400.5 ± 190 U/l ([M30-difference] M30-D) and 584.6 ± 335.4 U/l (M65-D), respectively. Patients with serum M30-D of <400.5 U/l had better median PFS and OS times than patients with M30-D >400.5 U/l (PFS, 9.9 vs. 4.3 months, p = 0.018 and OS, 13.6 vs. 8.1 months, p = 0.029). In addition, median PFS and OS intervals in patients with serum M65-D > 584.6 U/l were significantly worse than those of patients whose M65-D was lower than or equal to 584.6 U/l (4.1 vs. 11.4 months for PFS, p = 0.002 and 5.7 vs. 13.6 months for OS, p = 0.005). Patients with values above M30-D and M65-D had a better tumor response compared with patients with values below M30-D and M65-D (p = 0.02 and p = 0.006, respectively). In the logistic regression analysis, only M65-D was significantly found to be an independent factor in predicting response to chemotherapy (p = 0.018, OR:1.4). However, only M30 levels after chemotherapy were found to be an independent prognostic factor for PFS in the multivariate analysis. These results showed for the first time that both M30 and M65 in serum samples of patients with advanced gastric cancer were elevated 48 h after chemotherapy and these were poor prognostic factors for both PFS and OS of patients. Moreover, increased serum M65 levels after chemotherapy can be predict tumor response.

Serum cytokeratin 18 as a biomarker for gastric cancer. Clin Exp Med 2012; 13:289-95.

Abstract
Cytokeratin 18 (CK18) fragments are released into circulation during epithelial cell death. M30 (reflects caspase-cleaved CK18 fragment) and M65 (reflects total CK18 fragment) enzyme-linked immunosorbent assay (ELISA) detect circulating CK18 fragments released during caspase-dependent or total cell death, respectively; thus, CK18 has the potential of being a biomarker for epithelial cancers. In the present study, we investigated the serum levels of M30 and M65 in patients with gastric cancer, determined correlation of these levels with clinical features, and evaluated the usefulness of these enzymes as diagnostic and prognostic markers. We enrolled 54 gastric cancer patients and 12 healthy volunteers in this study. We measured the serum levels of M30 and M65 by quantitative ELISA. The levels of M30 and M65 in gastric cancer patients were significantly higher than those in healthy volunteers (P = 0.001, P < 0.001). The enzyme levels were elevated with the progress of gastric cancer. The sensitivity and specificity of M30 as a diagnostic marker were 67.5 and 90.9 %, respectively, and those of M65 were 70.1 and 90.9 %, respectively. The serum levels of M30 and M65 in patient with early gastric cancer were elevated in 38.1 and 66.7 %, respectively. Further, increased serum level of M65 is an independent indicator of poor prognosis (P = 0.036). The serum levels of M30 and M65 may be useful biomarkers for gastric cancer as diagnostic markers that can reflect the extent of cancer. Moreover, M65 levels can be used as a prognostic indicator.

Abstract
Background Apoptosis is thought to be induced by chemotherapy in cancer patients. Therefore, the measurement of its amplitude may be a useful tool to predict the effectiveness of cancer treatment sooner than conventional methods do. Patients and methods In the study presented, apoptosis was assessed with an ELISA-based assay in which caspase-cleaved cytokeratin 18 (M30-antigen), a novel specific biomarker of apoptosis, is measured. Thirty seven patients with malignant (nonmetastatic and metastatic) breast cancer, 35 patients with benign breast disease, and 34 healthy subjects were studied. Cancer patients received neoadjuvant chemotherapy consisting of either fluorouracil, epirubicin, and cyclophosphamide (FEC) or epirubicin plus docetaxel (ED). Apoptosis was detected before chemotherapy, 24 and 48 h after chemotherapy in the malignant group. Results It was found that the baseline apoptosis level in either malignant but nonmetastatic group or benign group was not statistically different from that in the control group (p>0.05). However, it was statistically significantly higher in the metastatic group than that in the control group (p<0.05). Following the drug application, M30-antigen levels significantly increased at 24 h (p<0.05). The baseline M30-antigen levels increased about 3-times in patients showing tumor regression. Conclusions M30-antigen level is increased after chemotherapy and its measurement may help clinicians to predict the effectiveness of chemotherapy sooner in breast cancer cases although confirmative larger trials are needed.

Abstract
Method validation should focus on demonstrating that an assay is fit for its intended purpose. We have applied the β-expectation tolerance interval - a statistical approach that predicts the accuracy of assay measurements in the future - to the validation of two different cell death biomarker assays, the M30 and M65 ELISAs. A meta-analysis was conducted on a total of 57 different M30 and M65 assays run over a 2 year period. All code utilised in calculations was developed using MATLAB. The optimal fit to the calibration curve for the M30 assay was shown to be a quartic curve which yielded a β-expectation tolerance interval of +20.5% and -23.6% at β=95% over a wide range of QC standards (88-810 U/L). However, such a fit required at least 7 points to avoid problems with over fitting. A linear fit to the M65 calibration curve normally produced a tolerance interval of less than ±20%, however, marked inter-batch variations were evident. Amelioration of batch to batch variations was accomplished by fitting M65 calibration data preferably to a 4-parameter logistic function or a cubic spline. The minimum number of QC replicates and different assays required to produce reliable accuracy profiles was determined. The β-expectation tolerance interval approach has resulted in further optimisation of the M30 and M65 ELISAs as biomarker assays that should translate into greater accuracy in results generated from clinical trials samples.

Abstract
PURPOSE M30 and M65 are different circulating fragments of cytokeratin 18. They release during apoptotic cell death, so it is believed that they reflect cell death of epithelial tumors. The aim of this study was to determine the prognostic value of plasma M30 and M65 levels in predicting of survival for patients with advanced gastric cancer compare with healthy controls. METHODS Thirty-four patients with advanced gastric cancer and thirty-two healthy controls were included. Plasma M30 and M65 values were measured by quantitative ELISA method. RESULTS The median age of patients and control groups was 60 and 56 years, respectively. No difference was detected between patient and control groups with respect to plasma median M30 values (390.4 vs. 270.7 U/l, respectively, P = 0.10). The median plasma M65 values of patients were significantly higher than those of control group (1232.1 vs. 580.1 U/l, P < 0.001). The best cut-off values for plasma M30 and M65 for predicting progression-free survival (PFS) were 277.7 and 1434.9 U/l in ROC analysis. The patients whose plasma M30 values were higher than 277.7 U/l had worse PFS than patients with plasma M30 value <277.7 U/l (8.9 vs. 11.2, respectively, P = 0.01). The median PFS of patients whose M65 levels lower than or equal to 1434.9 U/l was better than that of patients whose M65 levels were >1434.9 U/l (12.4 vs. 10.4, respectively, P = 0.04). But plasma M30 and M65 level in patient group were not found to be an important prognostic factor for PFS in the multivariate analysis. CONCLUSIONS These results showed that plasma M65 values were significantly elevated in patients with advanced gastric cancer compared to healthy people. Moreover, both increased plasma M30 and M65 levels can predict PFS in patients with gastric cancer.
