Impact of Thrombocytopenia on Survival in Patients with Hepatocellular Carcinoma: Updated Meta-Analysis and Systematic Review. Cancers (Basel) 2024; 16:1293. [PMID: 38610973 PMCID: PMC11011012 DOI: 10.3390/cancers16071293] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2024] [Revised: 03/24/2024] [Accepted: 03/25/2024] [Indexed: 04/14/2024] Open
Abstract
BACKGROUND Platelets (PLT) have a role in the pathogenesis, progression, and prognosis of hepatocellular carcinoma (HCC) and could represent a readily measurable laboratory parameter to enhance the comprehensive evaluation of HCC patients. METHODS The PubMed, Web of Science, and Scopus databases were searched with a focus on survival as well as patient and tumor-specific characteristics in correlation to reported PLT counts. Survival outcomes were analyzed with both common-effect and random-effects models. The hazard ratio (HR) and its 95% confidence interval (CI) from analyzed trials were incorporated. Studies that did not provide survival data but focused on platelet count correlation with HCC characteristics were reviewed. RESULTS In total, 26 studies, including a total of 9403 patients, met our criteria. The results showed that thrombocytopenia in HCC patients was associated with poor overall survival (common-effect HR = 1.15, 95% CI: 1.06-1.25; random-effect HR = 1.30, 95% CI: 1.05-1.63). Moreover, three studies reveal significant correlations between PLT indices and tumor characteristics such as size, foci number, and etiology of HCC development. CONCLUSION Our meta-analysis confirmed that PLT count could act as a prognostic marker in HCC, especially with a PLT count cut off <100 × 103/mm3. Further prospective studies focusing on the role of PLT in clearly defined subgroups are necessary.

New and Old Key Players in Liver Cancer. Int J Mol Sci 2023; 24:17152. [PMID: 38138981 PMCID: PMC10742790 DOI: 10.3390/ijms242417152] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2023] [Revised: 11/27/2023] [Accepted: 11/28/2023] [Indexed: 12/24/2023] Open
Abstract
Liver cancer represents a major health problem worldwide with growing incidence and high mortality, hepatocellular carcinoma (HCC) being the most frequent. Hepatocytes are likely the cellular origin of most HCCs through the accumulation of genetic alterations, although hepatic progenitor cells (HPCs) might also be candidates in specific cases, as discussed here. HCC usually develops in a context of chronic inflammation, fibrosis, and cirrhosis, although the role of fibrosis is controversial. The interplay between hepatocytes, immune cells and hepatic stellate cells is a key issue. This review summarizes critical aspects of the liver tumor microenvironment paying special attention to platelets as new key players, which exert both pro- and anti-tumor effects, determined by specific contexts and a tight regulation of platelet signaling. Additionally, the relevance of specific signaling pathways, mainly HGF/MET, EGFR and TGF-β is discussed. HGF and TGF-β are produced by different liver cells and platelets and regulate not only tumor cell fate but also HPCs, inflammation and fibrosis, these being key players in these processes. The role of C3G/RAPGEF1, required for the proper function of HGF/MET signaling in HCC and HPCs, is highlighted, due to its ability to promote HCC growth and, regulate HPC fate and platelet-mediated actions on liver cancer.

Abstract
During fibrosis, (myo)fibroblasts deposit large amounts of extracellular matrix proteins, thereby replacing healthy functional tissue. In liver fibrosis, this leads to the loss of hepatocyte function, portal hypertension, variceal bleeding, and increased susceptibility to infection. At an early stage, liver fibrosis is a dynamic and reversible process, however, from the cirrhotic stage, there is significant progression to hepatocellular carcinoma. Both liver-resident macrophages (Kupffer cells) and monocyte-derived macrophages are important drivers of fibrosis progression, but can also induce its regression once triggers of chronic inflammation are eliminated. In liver cancer, they are attracted to the tumor site to become tumor-associated macrophages (TAMs) polarized towards a M2- anti-inflammatory/tumor-promoting phenotype. Besides their role in thrombosis and hemostasis, platelets can also stimulate fibrosis and tumor development by secreting profibrogenic factors and regulating the innate immune response, e.g., by interacting with monocytes and macrophages. Here, we review recent literature on the role of macrophages and platelets and their interplay in liver fibrosis and hepatocellular carcinoma.

Parameters Predicting Microvascular Invasion and Poor Differentiation in Hepatocellular Carcinoma Patients with Normal Alpha-fetoprotein Level Before Liver Transplantation. THE TURKISH JOURNAL OF GASTROENTEROLOGY : THE OFFICIAL JOURNAL OF TURKISH SOCIETY OF GASTROENTEROLOGY 2023; 34:753-759. [PMID: 37326153 PMCID: PMC10441150 DOI: 10.5152/tjg.2023.22538] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/27/2022] [Accepted: 09/28/2022] [Indexed: 06/17/2023]
Abstract
BACKGROUND/AIMS The aim of this study is to evaluate the parameters that might be associated with pathologically diagnosed microvascular invasion and poor differentiation, using complete blood count and routine clinical biochemistry test results, in hepatocellular carcinoma patients before liver transplantation. MATERIALS AND METHODS The data of patients who underwent liver transplantation for hepatocellular carcinoma at our institute, between March 2006 and November 2021, was researched retrospectively. RESULTS The incidence of microvascular invasion was 28.6%, poor differentiation rate was 9.3%, hepatocellular carcinoma recurrence rate after liver transplantation was 12.1%, and median time to recurrence was 13 months, in the patients with normal alpha-fetoprotein levels. After univariate and multivariate analysis, maximum tumor diameter >4.5 cm and the number of nodules (n > 5) were found to be independent risk factors for microvascular invasion, and number of nodules >4 and mean platelet volume ≤8.6 fL were found to be independent risk factors for poor differentiation. Serum alpha-fetoprotein levels were still within the normal range at the recurrence time, in 53% of the patients who had recurrence after liver transplantation, but surprisingly were elevated in 47% of the patients at time of hepatocellular carcinoma recurrence. CONCLUSIONS In hepatocellular carcinoma patients with normal alpha-fetoprotein levels before liver transplantation, independent risk factors of the presence of microvascular invasion were maximum tumor diameter and number of nodules, and independent risk factors of poor differentiation were mean platelet volume and number of nodules. Furthermore, serum alpha-fetoprotein levels were still normal at time of recurrence in 53% of hepatocellular carcinoma patients whose alpha-fetoprotein levels were normal before liver transplantation but were elevated in 47% of the patients at recurrence time, despite having normal levels before liver transplantation.

Abstract
Hepatitis B virus-associated acute-on-chronic liver failure (HBV-ACLF) is a common type of liver failure, which can occur in the context of chronic hepatitis B or cirrhosis compensatory period or decompensated period. HBV-ACLF progresses rapidly, is often complicated with multiple organ failure syndrome involving the liver, brain, heart, kidney, etc., and is associated with an extremely high short-term mortality rate. The American College of Gastroenterology (ACG) defines HBV-ACLF as a potentially reversible disease, and early diagnosis and standardized treatment will affect its prognosis. In recent years, the clinical application of some new scoring models and biomarkers has effectively improved the diagnosis and prognosis of HBV-ACLF. This article reviews some scoring models and test indexes recently used in the clinical treatment and explores their value in the diagnosis and prognosis of HBV-ACLF.

Abstract
BACKGROUND With the increasing incidence and prevalence of alcoholic liver disease, alcohol-related hepatocellular carcinoma has become a serious public health problem worthy of attention in China. However, there is currently no prognostic prediction model for alcohol-related hepatocellular carcinoma. METHODS The retrospective analysis research of alcohol related hepatocellular carcinoma patients was conducted from January 2010 to December 2014. Independent prognostic factors of alcohol related hepatocellular carcinoma were identified by Lasso regression and multivariate COX proportional model analysis, and the nomogram model was constructed. The reliability and accuracy of the model were assessed using the concordance index(C-Index), receiver operating characteristic (ROC) curve and calibration curve. Evaluate the clinical benefit and application value of the model through clinical decision curve analysis (DCA). The prognosis was assessed by the Kaplan-Meier (KM) survival curve. RESULTS In sum, 383 patients were included in our study. Patients were stochastically assigned to training cohort (n=271) and validation cohort (n=112) according to 7:3 ratio. The predictors included in the nomogram were splenectomy, platelet count (PLT), creatinine (CRE), Prealbumin (PA), mean erythrocyte hemoglobin concentration (MCHC), red blood cell distribution width (RDW) and TNM. Our nomogram demonstrated excellent discriminatory power (C-index) and good calibration at 1-year, 3-year and 5- year overall survival (OS). Compared to TNM and Child-Pugh model, the nomogram had better discriminative ability and higher accuracy. DCA showed high clinical benefit and application value of the model. CONCLUSION The nomogram model we established can precisely forcasting the prognosis of alcohol related hepatocellular carcinoma patients, which would be helpful for the early warning of alcohol related hepatocellular carcinoma and predict prognosis in patients with alcoholic hepatocellular carcinoma.

Abstract
Previous studies reported suppressive effects of antiplatelet agents on hepatocellular carcinoma (HCC); however, this has never been assessed in patients who underwent liver transplantation (LT). This retrospective observational study used data from LT recipients with pre-transplant HCC in a single tertiary hospital. The study population was divided into two groups according to the use of antiplatelet agents for >90 days within the study period (377 antiplatelet groups versus 91 non-antiplatelet groups). Matched groups containing 79 patients in each group were also compared regarding HCC-recurrence and HCC-related mortality, which were analyzed by treating non-HCC death as a competing risk. In Kaplan−Meier analyses of the matched cohort, the 5-year cumulative incidences of HCC recurrence and HCC-specific death were similar between the antiplatelet (p = 0.876) and non-antiplatelet groups (p = 0.701). All-cause and non-HCC deaths were also similar between the two groups (p = 0.867 and p = 0.413, respectively). In multivariable analyses of the entire cohort, antiplatelet use was not associated with HCC recurrence (hazard ratio [HR] 1.37, p = 0.300) or HCC-specific death (HR 1.54, p = 0.310). Therefore, unlike the usual setting with liver disease, antiplatelet therapy did not affect HCC recurrence or HCC-specific mortality when used after LT.

Changes in Inflammatory Markers Predict the Prognosis of Resected Hepatocellular Carcinoma with Child–Pugh A. Curr Oncol 2022; 29:5800-5809. [PMID: 36005195 PMCID: PMC9406633 DOI: 10.3390/curroncol29080457] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2022] [Revised: 08/13/2022] [Accepted: 08/15/2022] [Indexed: 12/01/2022] Open
Abstract
(1) Background: The reasons for changes in the inflammatory markers of patients with surgically resected hepatocellular carcinoma are unclear. We aimed to investigate the association of an inflammatory status with the prognosis of patients with hepatocellular carcinoma, who underwent surgical resection. (2) Methods: We retrospectively enrolled 91 patients with Child A hepatocellular carcinoma, who had received surgical resection, to explore the influence of preoperative inflammatory markers and postoperative changes on the prognosis. (3) Results: The platelet-to-lymphocyte ratio (PLR) and its alteration were independent prognostic factors. Patients with a low PLR had a significantly better recurrence-free survival (RFS) than those with a high PLR (1-year RFS of 88.5% versus 50.0%; 3-year RFS of 62.1% versus 25.0%, p = 0.038). The patients with a low PLR showed a significantly better overall survival (OS) than those with a high PLR (1-year OS of 98.9% versus 75.0%; 3-year OS of 78.2% versus 25.0%, p = 0.005). The patients whose PLR had increased at 6 months after operation showed a worse OS than patients whose PLR had decreased (1-year OS of 96.3% versus 98.4%; 3-year OS of 63.0% versus 79.7%, p = 0.048). However, neither the neutrophil-to-lymphocyte ratio nor Onodera’s prognostic nutritional index had any prognostic significance. (4) Conclusions: The PLR and its alteration are significant prognostic factors for the RFS and OS of patients with Child A hepatocellular carcinoma who had received curative surgery.

Abstract
OBJECTIVE The mean platelet volume (MPV) is a measure of platelet size, and it is considered a surrogate marker of platelet activation. Because the correlation between platelet count/size and lung cancer prognosis remains unclear, this meta-analysis comprehensively evaluated the prognostic significance of MPV among patients with lung cancer. METHODS A systematic search of PubMed, Embase, Google Scholar, and additional sources of relevant studies were conducted with no language restrictions from inception to 7 May 2021. Overall survival (OS) and disease-free survival (DFS)/progression-free survival (PFS), as well as their hazard ratios (HR) and 95% confidence intervals (CIs), were pooled to evaluate the relationship between MPV and survival. The study protocol was registered on PROSPERO. RESULTS Eleven studies involving 2421 patients with lung cancer were included in our analysis. Nine studies including only patients with non-small cell lung cancer were included in the meta-analysis. Our analysis revealed no significant associations of MPV with OS (HR = 1.09, 95% CI = 0.84-1.41) and DFS/PFS (HR = 1.13, 95% CI = 0.58-2.20). CONCLUSION Pretreatment MPV levels did not display prognostic significance in patients with NSCLC. Large-scale prospective studies and a validation study considering ethnicity and lung cancer staging are warranted.

Abstract
BACKGROUND Systemic inflammatory markers are associated with patient survival in pancreatic cancer (PC). The aim of this study was to investigate the prognostic significance of the systemic immune-inflammation index (SII) in PC patients who underwent radical surgery. Platelet-albumin-bilirubin (PALBI) grade is a composite evaluation index based on liver function. Patients with pancreatic head cancer are prone to obstructive jaundice, which leads to abnormal liver function. Based on this, we also explored the prognostic value of PALBI grade in PC patients. METHODS Patients with pathologically confirmed PC who had undergone radical surgery (with negative surgical margin) for the first time at the Affiliated Hospital of Qingdao University from January 2013 to December 2019 and followed up by December 2020 were retrospectively analyzed. Peripheral blood cell count is easily affected by infection or hematological diseases, which affects the results, so it is excluded. Clinical data and laboratory examination indexes were collected. The SII and PALBI grade were calculated. The cutoff values were determined using the Youden index. The Cox proportional hazards regression model was used to analyze the prognostic value of the SII and PALBI grade through univariate and multivariate survival analysis. RESULTS A total of 214 patients [median age, 60.29 years; 128 (59.8%) men] met the inclusion criteria. There were 140 patients (65.4%) with pancreatic head cancer according to the tumor location. They were divided into high and low SII or PALBI groups by cutoff values of 705 and -5.6, respectively. According to the multivariate analysis, SII (P<0.001) was an independent factor negatively associated with overall survival (OS) and disease-free survival (DFS). In patients with pancreatic head cancer, PALBI grade was associated with shorter OS (P=0.031). The combination of high SII and high PALBI grade had stronger predictive value for poor prognosis (log-rank test, P<0.001), which the OS was 11.3 months less than the combination of low two groups. CONCLUSIONS SII was a promising prognostic biomarker in PC. And PALBI grade also showed predictive value for patients with pancreatic head cancer. Therefore, it can help predict the treatment outcomes in these patients.

Abstract
The prognostic role of platelet count in hepatocellular carcinoma (HCC) remains unclear, and in fact both thrombocytopenia and thrombocytosis are reported as predictors of unfavourable outcomes. This study aimed to clarify the prognostic value of preoperative platelet count in potentially resectable HCC. We retrospectively reviewed 128 patients who underwent hepatic resection for HCC at a tertiary academic centre (2007−2019). Patient data were modelled by regression analysis, and platelet count was treated as a continuous variable. 89 patients had BCLC 0/A tumours and 39 had BCLC B tumours. Platelet count was higher in patients with larger tumours and lower in patients with higher MELD scores, advanced fibrosis, and portal hypertension (p < 0.001 for all listed variables). After adjusting for BCLC stage and tumour diameter, low platelet count associated with reduced overall survival (hazard ratio 1.25 per 50/nL decrease in platelet count, 95% confidence interval (CI) 1.02−1.53, p = 0.034) and increased perioperative mortality (odds ratio 1.96 per 50/nL decrease in platelet count, 95% CI 1.19−3.53, p = 0.014). Overall, low platelet count correlates with increased liver disease severity, inferior survival, and excess perioperative mortality in resectable HCC. These insights might be applied in clinical practice to better select patients for resection.

Abstract
BACKGROUND The aim of this study was to retrospectively evaluate the prognostic value of the pretreatment platelet (PLT) count in patients with hepatitis B virus (HBV)-related intermediate-advanced hepatocellular carcinoma (HCC) complicated with cirrhosis undergoing transcatheter arterial chemoembolization (TACE). RESEARCH DESIGN AND METHODS We assessed 362 patients with HBV-related intermediate-advanced HCC complicated with cirrhosis undergoing TACE. Patients were divided into low (≤96 × 109/L) and high (>96 × 109/L) PLT groups. Propensity score matching (PSM) was performed to eliminate the imbalance in potential confounding factors. The endpoint was time to progression (TTP). RESULTS After PSM, the high and low PLT groups had 97 patients each. The TTP was significantly longer in the low PLT group than in the high PLT group (log-rank test, p < 0.001). A high pretreatment PLT count was an independent predictor of poor tumor response (OR 4.724; 95% CI 1.889-11.815; P = 0.001) and short TTP (HR = 3.598; 95% CI: 2.570-5.036; P < 0.001). Subgroup analysis showed that a high PLT count increased the risk of progression across almost all subgroups. CONCLUSIONS The pretreatment PLT count has potential value in predicting the prognosis of patients with intermediate-advanced HCC undergoing TACE.

Abstract
Background and Aim With the control of viral hepatitis, alcoholic hepatocellular carcinoma (HCC) is becoming increasingly important in Japan. In alcoholic cirrhosis, the impact of portal hypertension is significant. Thus, it may be difficult to predict prognosis accurately with the reported prognostic scores. Here we propose the platelet‐albumin‐bilirubin tumor nodes metastasis (TNM) score (PALBI‐T score) as a prognostic model for HCC in alcoholic liver disease, and investigate its usefulness. The PALBI‐T score is an integrated score based on the TNM stage and PALBI grade including platelets, reflecting portal hypertension. Methods This study included 163 patients with alcoholic HCC treated at our Center from 1997 to 2018. We compared the prognostic prediction abilities of the Japan Integrated Staging (JIS) score, ALBI‐T score, and PALBI‐T score. The PALBI‐T score was calculated similarly to the JIS and ALBI‐T scores. Areas under the receiver operating characteristic curve (AUC) were calculated for predicting overall survival (OS). Results In predicting the 1‐year survival, the JIS score had a larger AUC (AUC = 0.925) than the ALBI‐T score (AUC = 0.895) and PALBI‐T score (AUC = 0.891). On the other hand, there was no significant difference in predicting OS among the integrated scores. The PALBI‐T score (AUC = 0.740) had the largest AUC, and the JIS score (AUC = 0.729) and ALBI‐T score (AUC = 0.717) were not significantly different from the PALBI grade (AUC = 0.634). The PALBI grade reflected the degree of portal hypertension. Conclusion In patients with alcoholic HCC, the Japan Integrated Staging score is useful for predicting short‐term prognosis. The PALBI‐T score, which reflects portal hypertension, appears to be a more valid prognostic score for predicting long‐term prognosis.

Abstract
Platelets are associated with the processes that aid in tumour growth and progression. Platelet Count (PLT) and platelet indices like Mean Platelet Volume (MPV), Platelet Large Cell Ratio (P-LCR), Plateletcrit (PCT) and Platelet Distribution Width (PDW) are markers that are linked with platelet activities in cancer. This review involves the evaluation of PLT, MPV and PCT in different cancers. Platelets actions should be always monitored during several diseases, as their potential exceeds the classical function in preventing bleeding. Vast roles of platelets were discovered in several biological functions. Therefore, studying their indices can be effective in the diagnosis of several disorders including cancer.

Abstract
Background: Increasing numbers of studies reported platelet (PLT)- related measures could play a creative role in many malignancies, while the prognostic impact of these measures in hepatocellular carcinoma (HCC) remains limited and controversial. It is worth exploring the predictive value of PLT-related measures in HCC. Methods: A total of 279 HCC patients with hepatectomy were analyzed in the retrospective cohort study. The optimal cut-off points of these PLT-related indices were obtained by the receiver operating characteristic (ROC) curve. The associations of these indices with clinical characteristics and overall survival (OS) were evaluated by Kaplan–Meier curves and Cox proportional hazards models. Results: High PLT count and low prognostic nutritional index (low-PNI) were significantly associated with larger tumor size. The low gamma-glutamyl transpeptidase-to-platelet ratio (low-GPR) group was inclined to more hepatitis infections. Survival curves indicated that preoperative high-PLT, low-GPR, and low-PNI had a worse prognosis after surgery in the cohort. In addition, PLT≥220 × 109/L (HR, 2.274; 95% CI, 1.061-4.876; P = .035), PNI≥51.9 (HR, 0.503; 95% CI, 0.265-0.954; P = .035), and GPR≥0.2 (HR, 0.432; 95% CI, 0.204-0.912; P = .028) were identified as independent prognostic factors for survival outcomes in the multivariable analysis. Conclusion: High-PLT, low-GPR, and low-PNI as the preoperative predictors were associated with poor OS in HCC patients with hepatectomy. Our data reveal that they could be simple, easily obtained, and effective predictors for evaluation of survival outcomes in patients.

Antibiotic Therapy is Associated with Worse Outcome in Patients with Hepatocellular Carcinoma Treated with Sorafenib. J Hepatocell Carcinoma 2021; 8:1485-1493. [PMID: 34877268 PMCID: PMC8643200 DOI: 10.2147/jhc.s317957] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2021] [Accepted: 10/11/2021] [Indexed: 12/12/2022] Open
Abstract
Background Antibiotic treatment (ABT) affects the outcome of cancer patients treated with immune checkpoint inhibitors (ICIs) and chemotherapy, possibly by altering the gut microbiome. We investigated the impact of ABT on overall survival (OS) and progression-free survival (PFS) in patients with advanced HCC treated with sorafenib. Methods HCC patients treated with sorafenib between 05/2006 and 03/2020 at the Medical University of Vienna were retrospectively analyzed. ABT was defined as antibiotic use within 30 days prior to or after sorafenib initiation. Results Of 206 patients, the majority was male (n=171, 83%) with a mean age of 66±9.6 years. Half of patients (n=94, 46%) had impaired liver function (Child-Pugh stage B). Median time of follow-up was 10.8 (95% CI: 9.2-12.3) months. ABT was administered in 23 (11%) patients due to different types of proven or clinically suspected bacterial infections (n=17, 74%) and hepatic encephalopathy (n=6, 26%). The median duration of ABT was 14 (IQR: 12-30) days. Penicillin (n=13, 57%), followed by rifaximin (n=6, 26%), fluoroquinolones (n=3, 13%), and cephalosporins (n=1, 4%), was administered in the ABT group. The ABT group had a significantly shorter median OS (4.7 (95% CI: 3.2-6.1) months vs 11.4 (95% CI: 9.9-12.9) months, p=0.012), which was confirmed in multivariable analysis (HR: 1.91 (95% CI: 1.1-3.2), p=0.014). Similarly, PFS trended to be shorter in the ABT group (3.5 (95% CI: 1.6-5.4) months vs 4.8 (95% CI: 3.9-5.7) months, p=0.099). None of the 10 patients with complete or partial response was found in the ABT group. Conclusion ABT was independently associated with worse outcomes in sorafenib-treated HCC patients. Prospective studies are needed to elucidate the underlying mechanism.

A novel model based on interleukin 6 and insulin-like growth factor II for detection of hepatocellular carcinoma associated with hepatitis C virus. J Genet Eng Biotechnol 2021; 19:168. [PMID: 34714420 PMCID: PMC8556404 DOI: 10.1186/s43141-021-00262-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2021] [Accepted: 10/02/2021] [Indexed: 11/10/2022]
Abstract
BACKGROUND The coexistence of cirrhosis complicates the early detection of hepatocellular carcinoma (HCC). Thus, novel biomarkers for HCC early detection are needed urgently. Traditionally, HCC detection is carried out by evaluating alpha-fetoprotein (AFP) levels combined with imaging techniques. This work aimed to assess interleukin (IL-6) and insulin-like growth factor 2 (IGF 2) as possible HCC markers in comparison to AFP in patients with and without HCC. RESULTS ROC analysis showed that IGF2 had the highest area under the curve (AUC) for discriminating HCC from liver cirrhosis (0.86), followed by IL6 (0.82), AFP (0.72), and platelet count (0.6). A four-marker model was developed and discriminated HCC from liver cirrhosis with an AUC of 0.97. The best cut-off was 1.28, at which sensitivity and specificity were 90% and 85%, respectively. For small tumor (< 2 cm), the model had an AUC of 0.95 compared to AFP (0.72). Also, the model achieved perfect performance with AUC of 0.93, 0.94, and 0.95 for BCLC (0-A), CLIP (0-1), and Okuda (stage I), respectively, compared to AFP (AUC of 0.71, 0.69, and 0.67, respectively). CONCLUSIONS The four markers may serve as a diagnostic model for HCC early stages and help overcome AFP poor sensitivity.

Platelets: The Emerging Clinical Diagnostics and Therapy Selection of Cancer Liquid Biopsies. Onco Targets Ther 2021; 14:3417-3428. [PMID: 34079287 PMCID: PMC8164876 DOI: 10.2147/ott.s311907] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2021] [Accepted: 05/16/2021] [Indexed: 12/11/2022] Open
Abstract
Due to the inherent molecular heterogeneity of metastatic tumours and the dynamic evolution ability of tumour genomes, tumour tissues obtained through biopsy and other methods cannot capture all of the features of tumour genomes. A new diagnostic concept called “liquid biopsy” has received widespread attention in recent years. Liquid biopsy has changed the clinical practice of oncology and is widely used to guide targeted drug utilization, monitor disease progression and track drug resistance. The latest research subject in liquid biopsy is platelets. Platelets originate from multifunctional haematopoietic stem cells in the bone marrow haematopoietic system. They are small cells from the cytoplasm of bone marrow megakaryocytes. Their main physiological functions are to participate in the processes of physiological haemostasis and coagulation. Tumour cells transfer biomolecules (such as RNA) to platelets through direct contact and release of exosomes, which changes the platelet precursor RNA. Under the stimulation of tumour cells and the tumour microenvironment, platelet precursor mRNA is spliced into mature RNA and converted into functional protein to respond to external stimuli, forming tumour-educated platelets (TEPs). The detection of TEPs in the peripheral blood of patients is expected to be used in clinical tumour diagnosis. This emerging liquid biopsy method can replace and supplement the current tumour detection methods. Further research on the role of platelets in tumour diagnosis will help provide a novel theoretical basis for clinical tumour diagnosis.

Role of Lymphotoxin-α Gene Polymorphism in Hepatitis C Virus-Related Chronic Liver Disorders. Infect Drug Resist 2021; 14:1921-1930. [PMID: 34079302 PMCID: PMC8164674 DOI: 10.2147/idr.s306879] [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: 02/23/2021] [Accepted: 04/22/2021] [Indexed: 12/26/2022] Open
Abstract
Background Tumor necrosis factor (TNF) family includes lymphotoxin-alpha (LTA) which is a pro-inflammatory cytokine which plays a role in hepatic fibrogenesis. LTA gene polymorphism plays a role in different inflammatory and immunomodulatory diseases. This polymorphism is also suggested to affect chronic hepatitis C (CHC) infection course. Aim To study the contribution of LTA gene polymorphism in different chronic hepatitis C stages and hepatocellular carcinoma risk. Patients and Methods Our study included 108 chronic HCV patients grouped according to the disease stage. Group (A): CHC, group (B): liver cirrhosis (LC), group (C): LC with HCC, and group (D): healthy controls. Routine laboratory investigations, polymerase chain reaction (PCR) for quantification of HCV, abdominal ultrasonography, and Liver stiffness measurement (LSM) were done. Child–Turcotte–Pugh, Model for end-stage liver disease (MELD), and Fibrosis index based on 4 (FIB-4) scores were calculated. We used the PCR-restriction fragment length polymorphism technique for lymphotoxin-α genotyping. Results The A/G genotype was predominant in all groups. In HCC patients, G/G genotype was more frequent (31.8%) than in the LC group (19.4%), CHC group (17.8%), and controls (4.17%). A significant association was found between LTA genotypes and the child classes in HCC (P<0.01) but not in LC patients (P>0.05). HCC patients carrying A/G genotype had higher MELD scores than other genotypes. Multivariate binary logistic regression analysis confirmed that LTA G/G genotype and low platelet count were independent predictors for HCC development in patients with HCV-related LC. Conclusion Detection of LTA G/G genotype in chronic HCV patients could help to recognize high-risk patients for disease progression and HCC development.

Till Death Do Us Part-The Multifaceted Role of Platelets in Liver Diseases. Int J Mol Sci 2021; 22:ijms22063113.

Abstract
Platelets are tightly connected with the liver, as both their production and their clearance are mediated by the liver. Platelets, in return, participate in a variety of liver diseases, ranging from non-alcoholic fatty liver diseases, (viral) hepatitis, liver fibrosis and hepatocellular carcinoma to liver regeneration. Due to their versatile functions, which include (1) regulation of hemostasis, (2) fine-tuning of immune responses and (3) release of growth factors and cellular mediators, platelets quickly adapt to environmental changes and modulate disease development, leading to different layers of complexity. Depending on the (patho)physiological context, platelets exert both beneficial and detrimental functions. Understanding the precise mechanisms through which platelet function is regulated at different stages of liver diseases and how platelets interact with various resident and non-resident liver cells helps to draw a clear picture of platelet-related therapeutic interventions. Therefore, this review summarizes the current knowledge on platelets in acute and chronic liver diseases and aims to shed light on how the smallest cells in the circulatory system account for changes in the (patho)physiology of the second largest organ in the human body.

Abstract
Background Thrombocytopenia was reported both detrimental and advantageous to hepatocellular carcinoma (HCC). However, there is little evidence showing clearly the clinical value of preoperative thrombocytopenia on the surgical outcome of patients with small HCC. This retrospective study aimed at elucidating the correlation between preoperative thrombocytopenia and surgical outcome of small HCC patients within Milan criteria treated with liver resection. Methods Data of hepatitis B virus (HBV)-related small HCC patients were retrospectively analyzed, and we performed the propensity score matching (PSM) analysis to overcome the imbalance of clinicopathological features. Patients enrolled were subsequently categorized into two groups according to preoperative platelet counts: thrombocytopenia group and non-thrombocytopenia group. Survival outcomes of the patients in both groups were described with the Kaplan-Meier method, and the difference was compared with a log-rank test. Cox regression analysis was applied to identify the risk factors of surgical outcome. Results After PSM, the estimated 1-, 3-, and 5-year overall survival (OS) rates for small HCC patients in the thrombocytopenia group were 94.5%, 77.0%, and 57.6%, and 95.0%, 79.6%, and 68.0%, respectively, for small HCC patients in the non-thrombocytopenia group (P = 0.042). And the 1-, 3-, and 5-year estimated recurrence-free survival (RFS) rates for small HCC patients in the thrombocytopenia group were 70.4%, 51.0%, and 42.1%, and 83.8%, 63.7%, and 46.7%, respectively, for small HCC patients in the non-thrombocytopenia group (P = 0.035). Multivariate analysis indicated preoperative thrombocytopenia was a significant prognosticator of poor RFS (hazard ratio (HR) = 1.388, 95% confidence interval (CI) 1.028~1.874, P = 0.033). Conclusion Preoperative thrombocytopenia had an undesirable impact on the recurrence of small HCC patients treated with liver resection.

Abstract
BACKGROUND Long non-coding RNA (LncRNA) plays an important role in the occurrence and development of hepatocellular carcinoma (HCC). This study aims to establish an immune-related LncRNA model for risk assessment and prognosis prediction in HCC patients. METHODS Hepatocellular carcinoma patient samples with complete clinical data and corresponding whole transcriptome expression were obtained from the Cancer Genome Atlas (TCGA). Immune-related genes were acquired from the Gene Set Enrichment Analysis (GSEA) website and matched with LncRNA in the TCGA to get immune-related LncRNA. Least Absolute Shrinkage and Selection Operator (LASSO) regression was used for screening the candidate LncRNAs and calculating the risk coefficient to establish the prognosis model. Patients were divided into a high-risk group and a low-risk group depending on the median risk score. The reliability of the prediction was evaluated in the validation cohort and the whole cohort. GSEA and principal component analysis were used for function evaluation. RESULTS A total of 319 samples met the screening criteria and were randomly distributed across the training cohort and the validation cohort. After comparison with the IMMUNE_RESPONSE gene set and the IMMUNE_SYSTEM_PROCESS gene set, a total of 3094 immune-related LncRNAs were screened. Ultimately, four immune-related LncRNAs were used to construct a formula using LASSO regression. According to the formula, the low-risk group showed a higher survival rate than the high-risk group in the validation cohort and the whole cohort. The receiver operating characteristic curves data demonstrated that the risk score was more specific than other traditional clinical characteristics in predicting the 5-year survival rate for HCC. CONCLUSION The four-immune-related-LncRNA model can be used for survival prediction in HCC and guide clinical therapy.

Abstract
Background There is considerable evidence that platelets contribute to cancer growth and metastatic dissemination. In recent studies, altered mean platelet volume (MPV) has been associated with prognosis in different types of cancer. However, the prognostic role of the MPV in head and neck squamous cell cancer (HNSCC) is currently discussed controversially. The present study was performed to analyze and further elucidate the prognostic significance of the MPV in HNSCC. Methods A total of 319 oropharyngeal squamous cell cancer (OPSCC) patients treated with radiotherapy at a tertiary academic center were enrolled in the present study. Kaplan–Meier method as well as uni- and multivariate Cox proportional hazards were used to evaluate the impact of MPV on cancer-specific survival (CSS), locoregional control (LC) and recurrence-free survival (RFS). Results The median MPV was 10.30 fL (mean 10.26 ± 1.17fL). Univariate analyses showed a significant association of the MPV with CSS (HR 0.85, 95% CI 0.74–0.98, p = 0.025), LC (HR 0.86, 95% CI 0.74–0.99, p = 0.034) and RFS (HR 0.87, 95% CI 0.76–0.996; p = 0.043). In multivariate analysis, the MPV remained an independent prognostic factor for CSS (HR 0.77, 95% CI 0.63–0.93, p = 0.008), LC (HR 0.80, 95% CI 0.65–0.98, p = 0.030), and RFS (HR 0.83, 95% CI 0.685–0.999, p = 0.049). Conclusions Our findings indicate that the MPV is a prognostic marker in OPSCC patients and may contribute to future individual risk assessment.

Abstract
OBJECTIVES To explore the non-linear relationship between platelet count (PLT) and hepatocellular carcinoma (HCC) overall survival (OS). SETTING The study was done in Sun Yat-sen University Cancer Center (SYSUCC) from January 2007 to May 2012, a total of 5005 consecutive participants at SYSUCC were retrospectively reviewed, and 979 patients with Barcelona clinic liver cancer (BCLC) stage B were selected for the final analysis. PARTICIPANTS A total of 979 newly diagnosed patients with HCC with BCLC stage B were identified for the secondary analysis. Eight cases were excluded for missing data of PLT. MAIN OUTCOME MEASURES Cox proportional hazard regression models were used to calculate multivariable-adjusted HRs and 95% CIs for HCC. The non-linear relationship was estimated through a restricted cubic spline regression, and a two-piecewise Cox proportional hazards model was further performed to calculate the threshold effect. We used multiple imputation to deal with the missing data. RESULTS In the multivariate analysis, Log PLT was associated with a 91% risk increase in death (HR 1.91; 1.28 to 2.85) with adjustment for gender, Child-Pugh class, age × diameter of main tumour, both lobe with lesions × number of the intrahepatic lesions, alpha-fetoprotein (<25, ≥25) and lactic dehydrogenase (<245, ≥245). We also found a U-shape relationship between PLT and HCC OS at the inflexion point of 67.6×109/L. The HR was 0.12 (95% CI 0.03 to 0.52) for Log PLT≤10.83 and 3.07 (CI 1.91 to 4.92) for Log PLT>10.83 after adjusting for potential confounders. The core results were consistent with those from the sensitivity analysis. Besides, a significantly higher hazard risk was found in the patients with age <55, both lobes with lesions, tumour diameter >50, haemoglobin ≥120 and C reactive protein >10. CONCLUSION PLT was nonlinearly associated with HCC OS.

Elevated Platelet Count is Associated with Poor Survival After Transarterial Chemoembolization Treatment in Patients with Hepatocellular Carcinoma: A Cohort Study. J Hepatocell Carcinoma 2020; 7:191-199.

Abstract
Background Platelet count (PLT) has been proved as an essential biomarker for the survival of hepatocellular carcinoma (HCC). However, the prognostic value of PLT change (ΔPLT) is still uncertain. The aim of this study was to explore the relationship between ΔPLT and HCC survival after transarterial chemoembolization (TACE) treatment. Methods Cox proportional hazard regression models were used to calculate multivariable-adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for HCC. The non-linear relationship between ΔPLT and OS was estimated through a restricted cubic spline regression analysis, and a two-piece-wise Cox proportional hazard model was further performed to calculate the threshold effect. Results A total of 597 HCC patients treated with TACE were selected for the secondary analysis. Compared with the ΔPLT within ±20 (×109/L), ΔPLT≥20 (×109/L) was significantly associated with an 64% increase in risk of death (HR, 1.64; 95% CI: 1.21 to 2.22) after adjustment for confounding variables, but the association was not significant in the group of ΔPLT≤-20 (HR, 1.23; 95% CI: 0.92 to 1.63). We also found a U-shape relationship between ΔPLT and HCC survival at the turning point of ΔPLT as 0 (20×109/L). The HR for the death was 1.12 (95% CI: 1.06, 1.18) with ΔPLT≥0 (20×109/L) while 0.95 (95% CI: 0.92, 0.98) with ΔPLT<0 (20×109/L). After potential confounding factors were adjusted, the non-linear relationship between ΔPLT and OS was still significant (P=0.013). Besides, ΔPLT≥20 (×109/L) was associated with new lesions (OR, 2.74; 95% CI: 1.38 to 5.45). Conclusion Elevated PLT was associated with poor overall survival of HCC patients after TACE treatment.

Abstract
BACKGROUND & AIMS Thrombocytosis is associated with more aggressive tumour biology in many malignancies. There are limited data in patients with hepatocellular carcinoma (HCC), which often occurs in patients with cirrhosis and portal hypertension. We aimed to explore the prognostic value of thrombocytosis in two cohorts of patients with HCC. METHODS We included 3561 patients from Taiwan and 1145 patients from the USA. Thrombocytopenia was defined as platelet count < 150×109 /L and thrombocytosis as ≥ 300 × 109 /L at HCC diagnosis. We used multivariable Cox proportional hazard models to identify independent predictors of survival. RESULTS Thrombocytosis was present in 9.0% and 6.9% of Taiwan and USA patients respectively. Compared to patients with normal platelet counts and those with thrombocytopenia, patients with thrombocytosis had larger tumours, increased vascular invasion and a higher proportion had extrahepatic metastases in both cohorts. In multivariable analysis, thrombocytosis (aHR 1.40, 95% CI 1.23-1.60) and thrombocytopenia (aHR 1.13, 95% CI 1.04-1.23) were both associated with worse survival after adjusting for age, gender, liver disease aetiology, Child-Pugh score, maximal tumour size, tumour nodularity, vascular invasion, lymph node or distant metastasis, performance status and alpha-fetoprotein level. Patients with thrombocytosis had a median survival of 6 and 4 months in the Taiwan and USA cohorts, compared to 32 and 14 months for those with normal platelet counts and 38 and 16 months for thrombocytopenic patients. CONCLUSION Thrombocytosis is independently associated with increased tumour burden and worse overall survival among HCC patients.

Abstract
A low platelet count, one of parameters of portal hypertension, is clinically a predictor of postoperative mortality, while platelets induce tumor development during growth factor secretion. In this study, we retrospectively investigated whether high platelet count negatively affects the survival of patients with hepatocellular carcinoma (HCC). Patients undergoing initial and curative resection for HCC were included. Surgical outcomes were compared between the high platelet (platelet count ≥ 20 × 104/μL) and control (< 20 × 104/μL) groups in patients without cirrhosis and between the low platelet (< 10 × 104/μL) and control (≥ 10 × 104/μL) groups in patients with cirrhosis. Among patients without cirrhosis, tumor was larger (P < 0.001) and tumor thrombus was more frequent (P < 0.001) in the high-platelet group than in the control group. After a median follow-up period of 3.1 years (range 0.2-16.2), median overall survival was 6.3 years (95% confidence interval [CI], 5.3-7.8) and 7.6 years (6.6-10.9) in the high-platelet (n = 273) and control (n = 562) groups, respectively (P = 0.027). Among patients with cirrhosis, liver function was worse (P < 0.001) and varices were more frequent (P < 0.001) in the low-platelet group. The median overall survival of patients in the low-platelet group (n = 172) was significantly shorter than that of patients in the control group (n = 275) (4.5 years [95% CI, 3.7-6.0] vs. 5.9 years [4.5-7.5], P = 0.038). Taken together, thrombocytopenia indicates poor prognosis in HCC patients with cirrhosis, while thrombocytosis is a poor prognostic predictor for those without cirrhosis.

Abstract
BACKGROUND Thrombocytopenia is a common finding in patients with chronic liver disease. It is associated with poor clinical outcomes due to increased risk of bleeding after even minor procedures. We sought to determine an algorithm for pre-operative platelet transfusion in patients with cirrhosis and hepatocellular carcinoma (HCC) undergoing laparoscopic microwave ablation (MIS-MWA). METHODS A retrospective review identified all patients with cirrhosis and HCC who underwent MIS-MWA at a single tertiary institution between 2007 and 2019. Demographics, pre-operative and post-operative laboratory values, transfusion requirements, and bleeding events were collected. The analyzed outcome of bleeding risk included any transfusion received intra-operatively or a transfusion or surgical intervention post-operatively. Logistic regression models were created to predict bleeding risk and identify patients who would benefit from pre-operative transfusion. RESULTS There were 433 patients with cirrhosis and HCC who underwent MIS-MWA identified; of these, 353 patients had complete laboratory values and were included. Bleeding risk was evaluated through bivariate analysis of statistically and clinically significant variables. The accuracy of both models was substantiated through bootstrap validation for 500 iterations (model 1: ROC 0.8684, Brier score 0.0238; model 2: ROC 0.8363, Brier score 0.0252). The first model captured patients with both thrombocytopenia and anemia: platelet count < 60 × 109 / L (OR 7.75, p 0.012, CI 1.58-38.06) and hemoglobin < 10 gm/dL (OR 5.76, p 0.032, CI 1.16-28.63). The second model captured patients with thrombocytopenia without anemia: platelet count < 30 × 109/L (OR 8.41, p 0.05, CI 0.96-73.50) and hemoglobin > 10 gm/dL (OR 0.16, p 0.026, CI 0.031-0.80). CONCLUSION The prediction of patients with cirrhosis and HCC requiring pre-operative platelet transfusions may help to avoid bleeding complications after invasive procedures. This study needs to be prospectively validated and ultimately may be beneficial in assessment of novel therapies for platelet-based clinical treatment in liver disease.

Prognostic value of pretreatment platelet counts in lung cancer: a systematic review and meta-analysis. BMC Pulm Med 2020; 20:96. [PMID: 32312252 PMCID: PMC7171794 DOI: 10.1186/s12890-020-1139-5] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2019] [Accepted: 04/07/2020] [Indexed: 01/09/2023] Open
Abstract
Background The prognostic value of elevated pretreatment platelet counts remains controversial in lung cancer patients. We performed the present meta-analysis to determine its precise role in these patients. Methods We employed a multiple search strategy in the PubMed, EMBASE and Cochrane Library databases to identify eligible studies. Disease-free survival (DFS)/progression-free survival (PFS)/time to progression (TTP) and overall survival (OS) were used as outcomes with hazard ratios (HRs) and 95% confidence intervals (CIs). Heterogeneity among the studies and publication bias were also evaluated. Results A total of 40 studies including 16,696 lung cancer patients were eligible for the analysis. Overall, the pooled analysis showed that compared with normal platelet counts, elevated pretreatment platelet counts were associated with poorer OS (HR = 1.54, 95% CI: 1.37–1.72, P < 0.001) and poorer DFS/PFS/TTP (HR = 1.62, 95% CI: 1.33–1.98, P < 0.001) in patients with lung cancer. In subgroup analyses, elevated pretreatment platelet counts were also associated with poorer OS and DFS/PFS/TTP in most subgroups. There was no evidence of publication bias. Conclusions This meta-analysis revealed that elevated pretreatment platelet counts were an independent predictor of OS and DFS/PFS/TTP in lung cancer patients. Large-scale prospective studies and a validation study are warranted.

The systemic inflammatory response as a source of biomarkers and therapeutic targets in hepatocellular carcinoma. Liver Int 2019; 39:2008-2023.

Abstract
The pathogenesis of hepatocellular carcinoma (HCC) strongly relates to inflammation, with chronic up-regulation of pro-inflammatory mediators standing as a potential unifying mechanism that underscores the origin and progression of HCC independent of aetiology. Activation of the diverse pro-inflammatory mediators either within the tumour or its microenvironment is part of an active cross-talk between the progressive HCC and the host, which is known to influence clinical outcomes including recurrence after radical treatments and long-term survival. A number of clinical biomarkers to measure the severity of cancer-related inflammation are now available, most of which emerge from routine blood parameters including neutrophil, lymphocyte, platelet counts, as well as albuminaemia and C-reactive protein levels. In this review, we summarise the body of evidence supporting the biologic qualification of inflammation-based scores in HCC and review their potential in facilitating the prognostic assessment and treatment allocation in the individual patient. We also discuss the evidence to suggest modulation of tumour-promoting inflammation may act as a source of novel therapeutic strategies in liver cancer.

Abstract
In the last decade, numerous studies revealed physiologic and pathophysiologic roles of platelets beyond haemostasis, a process to prevent and stop bleeding. These include the activation of the immune system and the promotion of inflammation, infection and cancer. Hence, the emerging view on the role of platelets has shifted - platelets are now seen as alert "sentinels" of the immune compartment, rather than passive bystanders. Herein, we review well-established and newly discovered features of platelets that define their natural role in maintaining blood haemostasis, but also their functional relationship with other cells of the immune system. We focus on recent studies underlining functional involvement of platelets in chronic liver diseases and cancer, as well as the effects of anti-platelet therapy in these contexts. Finally, we illustrate the potential of platelets as possible diagnostic and therapeutic tools in liver disease based on recently developed methodologies.

Short- and long-term effects of transarterial chemoembolization on portal hypertension in patients with hepatocellular carcinoma. United European Gastroenterol J 2019; 7:850-858. [PMID: 31316789 PMCID: PMC6620878 DOI: 10.1177/2050640619840199] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/12/2018] [Accepted: 02/12/2019] [Indexed: 12/20/2022] Open
Abstract
Background Transarterial chemoembolization (TACE) affects hepatic perfusion, and might
have an impact on portal pressure in patients with hepatocellular carcinoma
(HCC). Objective The objective of this article is to report the secondary outcome “hepatic
hemodynamics” from the AVATACE trial, a prospective randomized,
placebo-controlled trial on the efficacy of conventional TACE in combination
with bevacizumab or placebo. Methods Hepatic venous pressure gradient (HVPG) was measured at baseline (prior to
first TACE), within nine days (“acute effects”), two months (“intermediate
effects”) and six months (“long-term effects”) after the first TACE. Results Of 28 patients with early-intermediate stage HCC, n = 20
(71%) had clinically significant portal hypertension (CSPH, HVPG ≥ 10 mmHg)
at baseline (median, 12 (interquartile range (IQR): 9–19) mmHg). TACE had
neither “acute effects” nor “intermediate effects” on HVPG. However, in 13
patients with available HVPG measurement at month 6, there was a significant
increase in HVPG (median, 16 (IQR: 11–19) mmHg) compared with baseline
(median, 10 (IQR: 5–12) mmHg; p = 0.007). Portal
hypertension-related complications occurred exclusively in patients with
CSPH (8 (40%) vs 0). Conclusions Repeated TACE was associated with a significant long-term increase in HVPG.
This should be considered when deciding whether to continue with TACE or
switch to systemic treatment, since CSPH drives the development of
complications.
