[PMID: 38181584 DOI: 10.1016/j.tice.2023.102298] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2023] [Revised: 12/29/2023] [Accepted: 12/30/2023] [Indexed: 01/07/2024]
Abstract
BACKGROUND AND AIMS The specific mechanisms underlying the inhibition of hepatocellular carcinoma (HCC) proliferation and metastasis by mitochondrial apoptosis are not yet fully understood. However, it plays a vital role in suppressing HCC's ability to proliferate and spread. The involvement of MRPL21, a member within the family of mitochondrial ribosomal proteins (MRPs), is well-documented in both cellular apoptosis and energy metabolism. This study aims to explore and unravel the underlying mechanisms through which MRPL21 contributes to mitochondrial apoptosis and resistance against apoptosis in HCC. METHODS To evaluate the level of MRPL21 expression at the gene and protein expression levels, analysis was performed on human liver samples and blood using techniques for quantification. A knockdown plasmid targeting MRPL21 was constructed to investigate its impact on the growth and apoptosis of hepatocellular carcinoma (HCC). To evaluate the impact of MRPL21 knockdown on hepatocellular carcinoma (HCC) cell proliferation and apoptosis, various assays were performed including CCK-8 assays, flow cytometry analysis, detection of reactive oxygen species (ROS), and assessment of mitochondrial membrane potential (MMP). Furthermore, the role of MRPL21 in TP53 mutation was examined using Nutlin-3. RESULTS In HCC tissues and blood samples, an upregulation of MRPL21 expression was observed when compared to samples obtained from healthy individuals, and it is correlated with a poor prognosis for HCC. Silencing MRPL21 can effectively suppress Hep3B and HCCLM3 cells proliferation by modulating the mitochondrial membrane potential, it triggers the generation of reactive oxygen species (ROS), thereby leading to G0/G1 cell cycle arrest and initiation of early apoptosis. Furthermore, by inhibiting P53 activity, Nutlin-3 treatment can enhance MRPL21-deficiency-mediated apoptosis in Hep3B and HCCLM3 cells. CONCLUSION Through its influence on TP53 mutation, MRPL21 promotes HCC proliferation and progression while conferring resistance to apoptosis. These findings suggest that MRPL21 holds promise as a valuable biomarker for the treatment of HCC.

EXOSC10 is a novel hepatocellular carcinoma prognostic biomarker: a comprehensive bioinformatics analysis and experiment verification. PeerJ 2023; 11:e15860. [PMID: 37701829 PMCID: PMC10494838 DOI: 10.7717/peerj.15860] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2023] [Accepted: 07/17/2023] [Indexed: 09/14/2023] Open
Abstract
Background Hepatocellular carcinoma (HCC) is a common malignant tumor. There are few studies on EXOSC10 (exosome component 10) in HCC; however, the importance of EXOSC10 for HCC remains unclear. Methods In the study, the prognosis value of EXOSC10 and the immune correlation were explored by bioinformatics. The expression of EXOSC10 was verified by tissue samples from clinical patients and in vitro experiment (liver cancer cell lines HepG2, MHCC97H and Huh-7; normal human liver cell line LO2). Immunohistochemistry (IHC) was used to detect EXOSC10 protein expression in clinical tissue from HCC. Huh-7 cells with siEXOSC10 were constructed using lipofectamine 3000. Cell counting kit 8 (CCK-8) and colony formation were used to test cell proliferation. The wound healing and transwell were used to analyze the cell migration capacity. Mitochondrial membrane potential, Hoechst 33342 dye, and flow cytometer were used to detect the change in cell apoptosis, respectively. Differential expression genes (DEGs) analysis and gene set enrichment analysis (GSEA) were used to investigate the potential mechanism of EXOSC10 and were verified by western blotting. Results EXOSC10 was highly expressed in tissues from patients with HCC and was an independent prognostic factor for overall survival (OS) in HCC. Increased expression of EXOSC10 was significantly related to histological grade, T stage, and pathological stage. Multivariate analysis indicated that the high expression level of EXOSC10 was correlated with poor overall survival (OS) in HCC. GO and GSEA analysis showed enrichment of the cell cycle and p53-related signaling pathway. Immune analysis showed that EXOSC10 expression was a significant positive correlation with immune infiltration in HCC. In vitro experiments, cell proliferation and migration were inhibited by the elimination of EXOSC10. Furthermore, the elimination of EXOSC10 induced cell apoptosis, suppressed PARP, N-cadherin and Bcl-2 protein expression levels, while increasing Bax, p21, p53, p-p53, and E-cadherin protein expression levels. Conclusions EXOSC10 had a predictive value for the prognosis of HCC and may regulate the progression of HCC through the p53-related signaling pathway.

Abstract
Approximately 80% of primary liver cancer (PLC) is hepatocellular carcinoma (HCC), and the prognosis of HCC patients is unfavorable. Further studies are required to develop new prognostic tools for predicting the HCC patients' prognosis. The univariate Cox and LASSO regression were utilized to develop the multi-gene risk score. Single-sample Gene Set Enrichment Analysis (ssGSEA) was employed to assess differences of immune functions and cells. The model performance was evaluated by calibration curve and receiver operating characteristic curve (ROC). And qRT-PCR was utilized to evaluate the genes expression in clinical samples. Finally, a novel five-gene (KIF20A, CENPA, HMMR, G6PD, and ADH4) risk score was developed. Based on the median value of patients' risk scores, patients were divided into two groups: high-risk group and low-risk group. The Overall survival (OS) of patients in high-risk group was obviously poorer than that in the low-risk group. And the five-gene risk score was an independent risk factor correlated with patients' OS. Besides, a nomogram consisting of TNM stage and risk score was established. The results of decision curve, calibration curve, and ROC presented that the prognostic risk score and the nomogram had great predictive capability. Besides, ADH4's mRNA was reduced in HCC tissues, while the mRNA of KIF20A, CENPA, HMMR, and G6PD were overexpressed in HCC tissues. We developed a novel five-gene risk score that could predict HCC patients' prognosis. And these five genes could be promising therapeutic targets for HCC. The five-gene risk score and nomogram may be useful prognostic tools for HCC.

Abstract
Background The overall survival of patients with pancreatic cancer is extremely low. Despite multiple large-scale studies, identification of predictors of patient survival remains challenging. This study aimed to investigate the prognostic factors for pancreatic cancer. Methods The clinical data of 625 patients with pancreatic cancer treated at Shengjing Hospital of China Medical University from January 2013 to December 2017 were collected. Results Of 625 patients, 569 were followed from 1 to 75 months. The median overall survival was 9.3 months. The overall 1-, 3-, and 5-year survival rates were 37.8%, 15.1%, and 10.5%, respectively. Cox proportional hazards model indicated that baseline carbohydrate antigen 199 level, neutrophil-lymphocyte ratio, operative procedure, lymph node metastasis, number of distant organ metastasis, and postoperative adjuvant chemotherapy were independent prognostic factors of patients with pancreatic cancer. Baseline carbohydrate antigen 199 level, degree of weight loss, operative procedure, lymph node metastasis, number of distant organ metastasis, and postoperative adjuvant chemotherapy were independent prognostic factors of pancreatic head cancer subgroup. Baseline carbohydrate antigen 199 level, carcinoembryonic antigen level, total bilirubin level, neutrophil-lymphocyte ratio, peripancreatic invasion, number of distant organ metastasis, and postoperative adjuvant chemotherapy were independent prognostic factors of the pancreatic body/tail cancer subgroup. Conclusions Higher carbohydrate antigen 199 levels, neutrophil-lymphocyte ratio, lymph node metastasis and distant organ metastasis predict a poor prognosis in patients with pancreatic cancer. Early detection, early radical surgery and adjuvant chemotherapy are needed to improve prognosis for this deadly disease.

Abstract
Hepatectomy and transplantation are the main surgical therapies for HCC patients, and radiotherapy or chemotherapy is often used as adjuvant treatment. Researches have evaluated the independent predictors of HCC, but evidence for factors predicting the efficacy of chemotherapy is rare. Patients diagnosed with HCC between 2010 and 2015 from the SEER database were included and randomly divided into non-chemotherapy and chemotherapy groups. The predictors of CSS and OS were analyzed with the Cox proportional-hazards regression model and Fine and Gray’s competing risk model. Although there was no significant difference in survival analysis between the chemotherapy and non-chemotherapy groups, the cumulative cancer-specific mortality of most HCC patients was decreased in the chemotherapy group. AJCC stage, tumor size, grade, surgery and radiotherapy were predictors of OS and CSS in the non-chemotherapy group, while AJCC stage, tumor size, AFP, grade and surgery in the chemotherapy group. Surgery combined with chemotherapy was applicable to all AJCC stage patients. Surgery was the major treatment option for patients in AJCC I and AJCC II stage, and chemotherapy in AJCC III and AJCC IV stage. In conclusion, the study provided population-based estimates of the prognostic factors in HCC patients with or without chemotherapy.

Abstract
BACKGROUND The importance of regional lymph node sampling (LNS) during resection of hepatocellular carcinoma (HCC) is poorly understood. This study sought to ameliorate this knowledge gap through a nationwide population-based analysis. METHODS Patients who underwent liver resection (LR) for HCC were identified from Surveillance, Epidemiology and End Results (SEER-18) database (2003-2015). Cohort-based clinicopathologic comparisons were made based on completion of regional LNS. Propensity-score matching reduced bias. Overall and disease-specific survival (OS/DSS) were analyzed. RESULTS Among 5395 patients, 835 (15.4%) underwent regional LNS. Patients undergoing LNS had larger tumors (7.0vs4.8 cm) and higher T-stage (30.9 vs. 17.6% T3+, both p < 0.001). Node-positive rate was 12.0%. Median OS (50 months for both) and DSS (28 vs. 29 months) were similar between cohorts, but node-positive patients had decreased OS/DSS (20/16 months, p < 0.01). Matched patients undergoing LNS had equivalent OS (46 vs. 43 months, p = 0.869) and DSS (27 vs. 29 months, p = 0.306) to non-LNS patients. The prognostic impact of node positivity persisted after matching (OS/DSS 24/19 months, p < 0.01). Overall disease-specific mortality were both independently elevated (overall HR 1.71-unmatched, 1.56-matched, p < 0.01; disease-specific HR 1.40-unmatched, p < 0.01, 1.25-matched, p = 0.09). CONCLUSION Regional LNS is seldom performed during resection for HCC, but it provides useful prognostic information. As the era of adjuvant therapy for HCC begins, surgeons should increasingly consider performing regional LNS to facilitate optimal multidisciplinary management.

Abstract
BACKGROUND Chemotherapy is the standard of treatment for metastatic gallbladder carcinoma (GBC). It is unclear whether chemotherapy plus surgery improves the survival outcomes of patients with isolated liver metastases from GBC. We aimed to investigate the survival benefits of chemotherapy plus surgery in GBC with isolated liver metastases compared to those of chemotherapy alone. METHODS We identified 406 patients with isolated liver metastases from GBC who underwent chemotherapy alone or chemotherapy plus surgery between 2010 and 2015 from Surveillance, Epidemiology, and End Results. Patients were divided into 3 subgroups: group I, chemotherapy alone (n = 263); group II, chemotherapy combined with cholecystectomy (n = 116); and group III, chemotherapy combined with cholecystectomy plus hepatectomy (n = 27). The cancer-specific survival and overall survival were evaluated. RESULTS Compared with group I, group II revealed a longer survival time (P < .001). In addition, the survival time of the group III was also prolonged (P < .001). Multivariate cox analysis showed that treatment strategy was an independent prognostic factor. CONCLUSION Chemotherapy combined with resection of the primary tumor plus or not plus resection of the metastatic lesions may be beneficial in GBC with isolated liver metastases.

Abstract
Background Hepatocellular carcinoma (HCC) with high heterogeneity is one of the most frequent malignant tumors throughout the world. However, there is no research to establish a ferroptosis-related lncRNAs (FRlncRNAs) signature for the patients with HCC. Therefore, this study was designed to establish a novel FRlncRNAs signature to predict the survival of patients with HCC. Method The expression profiles of lncRNAs were acquired from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) database. FRlncRNAs co-expressed with ferroptosis-related genes were utilized to establish a signature. Cox regression was used to construct a novel three FRlncRNAs signature in the TCGA cohort, which was verified in the GEO validation cohort. Results Three differently expressed FRlncRNAs significantly associated with prognosis of HCC were identified, which composed a novel FRlncRNAs signature. According to the FRlncRNAs signature, the patients with HCC could be divided into low- and high-risk groups. Patients with HCC in the high-risk group displayed shorter overall survival (OS) contrasted with those in the low-risk group (P < 0.001 in TCGA cohort and P = 0.045 in GEO cohort). This signature could serve as a significantly independent predictor in Cox regression (multivariate HR > 1, P < 0.001), which was verified to a certain extent in the GEO cohort (univariate HR > 1, P < 0.05). Meanwhile, it was also a useful tool in predicting survival among each stratum of gender, age, grade, stage, and etiology,etc. This signature was connected with immune cell infiltration (i.e., Macrophage, Myeloid dendritic cell, and Neutrophil cell, etc.) and immune checkpoint blockade targets (PD-1, CTLA-4, and TIM-3). Conclusion The three FRlncRNAs might be potential therapeutic targets for patients, and their signature could be utilized for prognostic prediction in HCC.

Abstract
Purpose To investigate the prognostic factors and survival analysis of patients with hepatocellular carcinoma with distant metastasis. Methods The clinical data of 3,126 patients with distant metastasis of hepatocellular carcinoma from 2010 to 2015 were extracted from SEER database, and the correlation between the location of distant metastasis of hepatocellular carcinoma and prognosis was retrospectively analyzed. Patients were grouped according to different metastatic sites. The clinical characteristics of each group were compared by chi-square test, the survival curve was drawn by Kaplan-Meier method, Log-rank test was used for univariate analysis, and Cox regression for multivariate analysis. And use propensity score matching (PSM) to reduce differences in baseline characteristics. Results Before PSM, the prognosis of patients with hepatocellular carcinoma with lung metastasis is worse than that of patients without lung metastasis. And there was no statistically significant difference with or without bone metastases.Patients with one type of organ metastasis had better prognosis than those with multiple organ metastasis. Among patients with organ metastasis, bone metastasis has a better prognosis than patients with lung metastasis. After PSM, patients with HCC with bone metastases had a worse prognosis than those without bone metastases (P<0.05). Univariate analysis showed that the degree of tumor differentiation, T stage, N stage, primary tumor and metastatic surgery, radiotherapy and chemotherapy, tumor size, single organ metastasis, the number of metastatic organs, and the combination of metastatic organs were related to the prognosis of patients with distant metastasis of hepatocellular carcinoma (P < 0.05). Multiariate analysis showed that age ≥52 years old, male, low degree of tumor differentiation, N1 stage, no primary surgery, no chemoradiotherapy, tumor size > 6cm, and multi-organ metastasis were independent influencing factors for poor prognosis in patients with metastatic hepatocellular carcinoma. Conclusion The lung is the most common site of distant metastasis of hepatocellular carcinoma. Single organ metastasis has better prognosis than multiple organ metastasis. Age ≥52 years old, male, low degree of tumor differentiation, N1 stage, no primary surgery, no chemoradiotherapy, tumor size > 6cm, and multi-organ metastasis were independent influencing factors for poor overall survival and cancer-specific survival prognosis in patients with metastatic hepatocellular carcinoma.

A Real-World, Population-Based Analysis of the Outcomes of Colorectal Cancer Patients with Isolated Synchronous Liver or Lung Metastases Treated with Metastasectomy. World J Surg 2021; 44:1604-1611. [PMID: 31900570 DOI: 10.1007/s00268-019-05353-9] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/01/2023]
Abstract
OBJECTIVE To assess the survival outcomes among a contemporary cohort of colorectal cancer patients with isolated synchronous liver or lung metastases treated with or without surgical resection of the metastases. METHODS Surveillance, epidemiology and end results database has been accessed and cases with isolated liver or lung metastases diagnosed 2010-2015 have been accessed. Kaplan-Meier survival estimates were used to compare overall survival among patients who had or had not undergone metastasectomy. Multivariable Cox regression analysis was then used to assess the impact of metastasectomy on colorectal cancer-specific survival. RESULTS A total of 16,372 patients with colorectal cancer with isolated liver or lung metastases (M1a disease) were included in the current analysis (including 14,832 patients with isolated liver metastases and 1540 patients with isolated lung metastases). Patients who had undergone surgical resection of liver metastases have better overall survival compared to patients who had not undergone surgical resection of liver metastases (median overall survival: 38.0 months vs. 13.0 months; P < 0.001). Likewise, patients who had undergone surgical resection of lung metastases have better overall survival compared to patients who had not undergone surgical resection of lung metastases (median overall survival: 45.0 months vs. 19.0 months; P < 0.001). In a multivariable Cox regression analysis and among patients with isolated liver metastases, surgery to the metastases was associated with a reduced hazard of death (hazard ratio (HR) 0.567; 95% CI 0.529-0.609; P < 0.001). Likewise, and among patients with isolated lung metastases, surgery to the metastases was associated with a reduced hazard of death (HR 0.482; 95% CI 0.349-0.665; P < 0.001). CONCLUSION In a contemporary cohort, metastasectomy seems to be associated with improvement in overall and cancer-specific survival among patients with isolated synchronous liver or lung metastases from colorectal cancer. Whether this survival difference is totally ascribed to the effect of metastasectomy or it is the fact that patients who were eligible for surgical resection have limited disease extent and better medical profile (thus, leading to better survival) is unclear from such a population-based study.

Abstract
MicroRNA 155 (miRNA-155) is frequently dysregulated in hepatocellular carcinoma (HCC) and other cancer types. Toll-like receptor 3 (TLR3), a putative miR-155 target, plays a key role in liver pathophysiology, and its downregulation in HCC cells is associated with apoptosis evasion and poor outcomes. Herein, we examined the ability of in situ self-assembled Au-antimiR-155 nanocomplexes (Au-antimiRNA NCs) to activate TLR3 signaling in HCC cells. Gene expression analysis confirmed an inverse relationship between miR-155 and TLR3 expression in HCC samples, and marked upregulation of miR-155 was observed in HCC cells but not in normal L02 hepatocytes. RNA immunoprecipitation confirmed physical interaction between miR-155 and TLR3, while negative regulation of TLR3 expression by miR-155 was demonstrated by luciferase reporter assays. Au-antimiR-155 NCs were self-assembled within HepG2 HCC cells, but not within control L02 cells. They efficiently silenced miR-155, thereby inhibiting proliferation and migration and inducing apoptosis in HepG2 cells. Molecular analyses suggested these effects are secondary to TLR3 signaling mediating NF-κB transcription, caspase-8 activation, and interleukin-1β (IL-1β) release. Our results provide a basis for future studies examining the in vivo applicability of this novel Au-antimiRNA NCs delivery system to halt HCC progression by activating pro-apoptotic TLR3 signaling.

Abstract
AIM Hepatocellular carcinoma (HCC) is a common malignancy associated with a poor prognosis due to difficulties in reliably estimating overall survival (OS). MicroRNAs (miRNAs) play critical roles in HCC initiation, progression, and metastasis and are highly correlated with patient prognosis. Thus, miRNA-based risk signatures and nomograms are urgently required for predicting OS in patients with HCC. METHODS We constructed a 13-miRNA-based signature and prognostic nomogram using 408 HCC samples and 58 normal tissues with miRNA sequencing data and clinical data from 323 patients downloaded from The Cancer Genome Atlas. A total of 195 patients were assigned as the internal validation cohort for verification and testing. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analysis was applied to investigate pathway enrichment for the signature. RESULTS We identified and validated a 13-miRNA risk signature highly associating with the OS of HCC patients. The signature showed good performances by calculating C-index, area under the curve, and calibration curves. After verification and testing using an internal validation cohort, the results yielded a miRNA-based signature and a prognostic nomogram with reliable predictive accuracy. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analysis indicated that various genes and multiple pathways were closely related to the mechanisms of HCC proliferation and metastasis. CONCLUSION We successfully identified a 13-miRNA-based signature and prognostic nomogram that are capable of predicting OS in patients with HCC.

Abstract
Background Hepatocellular carcinoma (HCC) is one of the most universal malignant liver tumors worldwide. However, there were no systematic studies to establish glycolysis‑related gene pairs (GRGPs) signatures for the patients with HCC. Therefore, the study aimed to establish novel GRGPs signatures to better predict the prognosis of HCC. Methods Based on the data from Gene Expression Omnibus, The Cancer Genome Atlas (TCGA) and International Cancer Genome Consortium databases, glycolysis-related mRNAs were used to construct GRGPs. Cox regression was applied to establish a seventeen GRGPs signature in TCGA dataset, which was verified in two validation (European and American, and Asian) datasets. Results Seventeen prognostic GRGPs (HMMR_PFKFB1, CHST1_GYS2, MERTK_GYS2, GPC1_GYS2, LDHA_GOT2, IDUA_GNPDA1, IDUA_ME2, IDUA_G6PD, IDUA_GPC1, MPI_GPC1, SDC2_LDHA, PRPS1_PLOD2, GALK1_IER3, MET_PLOD2, GUSB_IGFBP3, IL13RA1_IGFBP3 and CYB5A_IGFBP3) were identified to be significantly progressive factors for the patients with HCC in the TCGA dataset, which constituted a GRGPs signature. The patients with HCC were classified into low-risk group and high-risk group based on the GRGPs signature. The GRGPs signature was a significantly independent prognostic indicator for the patients with HCC in TCGA (log-rank P = 2.898e−14). Consistent with the TCGA dataset, the patients in low-risk group had a longer OS in two validation datasets (European and American: P = 1.143e−02, and Asian: P = 6.342e−08). Additionally, the GRGPs signature was also validated as a significantly independent prognostic indicator in two validation datasets. Conclusion The seventeen GRGPs and their signature might be molecular biomarkers and therapeutic targets for the patients with HCC.

Abstract
Hepatocellular carcinoma (HCC) accounts for approximately 85-90% of all liver cancer cases and has poor relapse-free survival. There are many gene expression studies that have been performed to elucidate the genetic landscape and driver pathways leading to HCC. However, existing studies have been limited by the sample size and thus the pathogenesis of HCC is still unclear. In this study, we performed an integrated characterization using four independent datasets including 320 HCC samples and 270 normal liver tissues to identify the candidate genes and pathways in the progression of HCC. A total of 89 consistent differentially expression genes (DEGs) were identified. Gene-set enrichment analysis revealed that these genes were significantly enriched for cellular response to zinc ion in biological process group, collagen trimer in the cellular component group, extracellular matrix (ECM) structural constituent conferring tensile strength in the molecular function group, protein digestion and absorption, mineral absorption and ECM-receptor interaction. Network system biology based on the protein-protein interaction (PPI) network was also performed to identify the most connected and important genes based on our DEGs. The top five hub genes including osteopontin (SPP1), Collagen alpha-2(I) chain (COL1A2), Insulin-like growth factor I (IGF1), lipoprotein A (LPA), and Galectin-3 (LGALS3) were identified. Western blot and immunohistochemistry analysis were employed to verify the differential protein expression of hub genes in HCC patients. More importantly, we identified that these five hub genes were significantly associated with poor disease-free survival and overall survival. In summary, we have identified a potential clinical significance of these genes as prognostic biomarkers for HCC patients who would benefit from experimental approaches to obtain optimal outcome.

Abstract
Background Hepatocellular carcinoma (HCC) is a malignant tumor with frequent intrahepatic metastases; extrahepatic metastases are not rare but less frequent compared to intrahepatic ones. The most frequent sites of extrahepatic metastases are the lungs, followed by the lymph nodes, bones, and adrenal glands. Case report covering gastrointestinal (GI) tract involvement from HCC is limited. Case presentation A 60-year-old man was referred to us in May 2019 with a diagnosis of sigmoid colon tumor. The patient had a history of HCC and had received two stages of open resections for the primary and the abdominal metastasis successively and many times of transcatheter arterial chemoembolization (TACE). The sigmoid colon tumor received Hartmann procedure after abdominal enhanced computerized tomography (CT) scan and colonoscopy, while postoperative pathology and immunohistochemistry identified it as extrahepatic colonic metastasis from HCC. Conclusions The ratio of extrahepatic metastasis to the digestive tract was very low, and the majority was upper gastrointestinal involvement because of direct invasion or intraperitoneal implantation. TACE may be the risk factor of retrograde hematogenous metastasis to the downstream colon.

Abstract
Objectives Integrin beta‐like 1 (ITGBL1) is involved in the migration and invasion of several cancers; however, its roles in the development and progression of hepatocellular carcinoma (HCC) remain largely unknown. Materials and methods Immunohistochemistry staining was used to investigate the expression pattern of ITGBL1 and its prognostic values in HCC patients. The transwell, wound‐healing assays, xenograft and orthotopic mouse models were employed to determine the effects of ITGBL1 on HCC cell migration and invasion in vitro and in vivo. The biological mechanisms involved in cell migration and invasion caused by ITGBL1 were determined with Western blotting and RT‐PCR methods. Results ITGBL1 expression was significantly increased in HCC tissues compared to adjacent normal tissues. Patients with higher ITGBL1 expression were associated with more reduced overall survival. ITGBL1 overexpression promoted migration and invasion in SMMC‐7721 and HepG2 cells in vitro and in vivo, whereas knockdown or knockout ITGBL1 in CSQT‐2 cells significantly reduced cell migration and invasion abilities. In SMMC‐7721 cells, ITGBL1 overexpression stimulated TGF‐β/Smads signalling pathway, along with the KRT17 and genes involved in the epithelial‐mesenchymal transition (EMT). In contrast, ITGBL1 knockout inhibited the TGF‐β/Smads signalling pathway in CSQT‐2 cells. Conclusions These findings suggested that ITGBL1 promoted migration and invasion in HCC cells by stimulating the TGF‐β/Smads signalling pathway. ITGBL1 could be a promising prognostic biomarker, as well as a potential therapeutic target in HCC.

Abstract
Background: Tumor mutational burden (TMB) was verified to be closely associated with immune checkpoint inhibitors, but it is unclear whether gene mutation has an effect on immunotherapy of hepatocellular carcinoma (HCC). This research aimed to investigate the underlying correlation between gene mutation and immunotherapy in HCC. Methods: The somatic gene mutation data and gene expression data were retrieved from International Cancer Genome Consortium database and The Cancer Genome Atlas (TCGA) database. The mutational genes were selected by the intersection of three cohorts and further identified using survival analysis and TMB correlation analysis. After the identification of key mutational gene, we explored the correlation between gene mutation and both the immune cell infiltration and immune inhibitors. The signaling pathways associated with gene mutation were confirmed through gene set enrichment analysis. Furthermore, the survival analysis and mutational analysis based on TCGA cohort were performed for the validation of included gene. Results: As one of the frequently mutational genes in HCC, CTNNB1 was finally included in our research, for which it showed the significant result in survival analysis and the positive association with TMB of the three cohorts. Meanwhile, the validation of TCGA showed the significant results. Furthermore, natural killer (NK) cells and neutrophil were found to significantly infiltrate CTNNB1 mutation group from two cohorts. Besides, further analysis demonstrated that four types of immune inhibitors (CD96, HAVCR2, LGALS9, and TGFB1) were downregulated in CTNNB1 mutation group. Conclusion: Our research firstly revealed the underlying association between CTNNB1 mutation and immunotherapy, and we speculated that CTNNB1 mutation may modulate NK cells by affecting CD96. However, more functional experiments should be performed for verification.

Abstract
Aim: To evaluate the impact of cytoreductive surgery on the outcomes of patients with metastatic appendiceal carcinoma. Methods: Surveillance, Epidemiology and End Results (SEER) database was accessed and patients with metastatic appendiceal carcinoma diagnosed (2010-2015) were reviewed. Kaplan-Meier survival estimates/log-rank testing were then used to assess overall survival outcomes according to cytoreductive surgery. Multivariable Cox regression analysis was then used to evaluate factors affecting cancer-specific survival. Factors included in this model were age, race, sex, stage and histology and cytoreductive surgery. Results: A total of 1339 patients with metastatic appendiceal carcinoma were included in the current study. Using Kaplan-Meier survival estimates to evaluate overall survival, patients with surgery for metastatic disease have better overall survival compared with patients without surgery for metastatic disease (p < 0.001). Stratifying survival analysis according to histology, the overall survival benefit from surgery for the metastases seems to be limited to patients with mucinous adenocarcinoma (p = 0.002) rather than patients with nonmucinous adenocarcinoma (p = 0.401). Multivariable Cox regression analysis was then conducted to evaluate factors predicting cancer-specific survival. The following factors were associated with worse cancer-specific survival: African-American race (hazard ratio [HR]: 1.356; 95% CI: 1.036-1.774; p = 0.026), more advanced stage (HR: 3.910; 95% CI: 2.735-5.588; p < 0.001), nonmucinous adenocarcinoma (HR for signet ring carcinoma vs mucinous adenocarcinoma: 2.119; 95% CI: 1.674-2.683; p < 0.001) and no surgical resection of metastatic disease (HR: 1.273; 95% CI: 1.067-1.519; p < 0.001). Conclusion: The current study suggests that among patients with metastatic appendiceal carcinoma, surgical cytoreduction of metastatic disease is associated with improved outcomes for patients with mucinous adenocarcinoma but not in patients with nonmucinous adenocarcinoma.

Abstract
Aim: Our aim was to analyze the clinicopathological features of lung, liver, bone and brain metastasis in patients with endometrial cancer (EC). Patients & methods: We screened patients diagnosed with EC between 2010 and 2015 from the Surveillance, Epidemiology and End Results database. Results: Among 69,027 eligible EC patients, lung metastasis was the most common. Patients with lung or liver metastasis were at higher risk of bone and brain metastases than those without lung and liver metastasis. Brain metastasis has the lowest survival time (5.0 months) in single organ metastasis. Liver and brain metastasis have the highest death rate in two organ metastasis, and lung, liver and brain metastasis had the lowest survival time (1.0 month) in multi-sites metastasis. Conclusion: Lung metastasis was the most common in EC patients. Assessing distant organ metastasis may help clinicians to determine appropriate follow-up strategy for patients with EC.

Abstract
Objective Hepatocellular carcinoma (HCC) has become the second most common tumor type that contributes to cancer‐related death worldwide. The study aimed to establish a robust immune‐related gene pair (IRGP) signature for predicting the prognosis of HCC patients. Methods Two RNA‐seq datasets (The Cancer Genome Atlas Program and International Cancer Genome Consortium) and one microarray dataset (http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE14520) were included in this study. We used a series of immune‐related genes from the ImmPort database to construct gene pairs. Lasso penalized Cox proportional hazards regression was employed to develop the best prognostic signature. We assigned patients into two groups with low immune risk and high immune risk. Then, the prognostic ability of the signature was evaluated by a log‐rank test and a Cox proportional hazards regression model. Results After 1000 iterations, the 33‐immune gene pair model obtained the highest frequency. As a result, we chose the 33 immune gene pairs to establish the immune‐related prognostic signature. As we expected, the immune‐related signature accurately predicted the prognosis of HCC patients, and high‐risk groups showed poor prognosis in the training datasets and testing datasets as well as in the validation datasets. Furthermore, the immune‐related gene pair (IRGP) signature also showed higher predictive accuracy than three existing prognostic signatures. Conclusion Our prognostic signature, which reflects the link between the immune microenvironment and HCC patient outcome, is promising for prognosis prediction in HCC.

Oncol Lett 2019; 18:6704-6724. [PMID: 31807180 PMCID: PMC6876336 DOI: 10.3892/ol.2019.11031] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2019] [Accepted: 09/27/2019] [Indexed: 02/06/2023] Open
Abstract
Hepatocellular carcinoma (HCC) is generally considered one of the most common gastrointestinal malignant tumors, characterized by high invasiveness and metastatic rate, as well as insidious onset. A relationship between carcinogenicity and aberrant microRNA-139-5p (miR-139-5p) expression has been identified in multiple tumors while the specific molecular mechanisms of miR-139-5p in HCC have not yet been thoroughly elucidated. A meta-analysis of available data from The Cancer Genome Atlas (TCGA), Gene Expression Omnibus, ArrayExpress and Oncomine databases, as well as the published literature, was comprehensively conducted with the aim of examining the impact of miR-139-5p expression on HCC. Additionally, predicted downstream target genes were confirmed using a series of bioinformatics tools. Moreover, a correlative biological analysis was performed to ascertain the precise function of miR-139-5p in HCC. The results revealed that the expression of miR-139-5p was noticeably lower in HCC compared with non-tumor liver tissues according to the pooled standard mean difference, which was -0.84 [95% confidence interval (CI): -1.36 to -0.32; P<0.001]. Furthermore, associations were detected between miR-139-5p expression and certain clinicopathological characteristics of TCGA samples, including tumor grade, pathological stage and T stage. Moreover, the pooled hazard ratio (HR) for overall survival (HR=1.37; 95% CI: 1.07-1.76; P=0.001) indicated that decreased miR-139-5p expression was a risk factor for adverse outcomes. Additionally, 382 intersecting genes regulated by miR-139-5p were obtained and assembled in signaling pathways, including 'transcription factor activity, sequence-specific DNA binding', 'pathways in cancer' and 'Ras signaling pathway'. Notably, four targeted genes that were focused in 'pathways in cancer' were identified as hub genes and immunohistochemical staining of the proteins encoded by these four hub genes in liver tissues, explored using the Human Protein Atlas database, confirmed their expression patterns in HCC and normal liver tissues Findings of the present study suggest that reduced miR-139-5p expression is capable of accelerating tumor progression and is associated with a poor clinical outcome by modulating the expression of downstream target genes involved in tumor-associated signaling pathways.

Abstract
Background The current study evaluates the validity and performance of the 8th edition of the American Joint Committee on Cancer (AJCC) staging system for small intestinal adenocarcinoma patients. Methods Surveillance, Epidemiology and End Results (SEER) database [2004-2015] was explored and AJCC 6th, 7th, and 8th versions were assigned for each patient. Through Kaplan-Meier estimates, overall survival analyses were conducted. Cox regression analysis (adjusted for age, race, gender, sub-site, grade and surgical treatment) was conducted for cancer-specific survival and additionally, pairwise hazard ratio comparisons were performed. Results A total of 2,997 small intestinal adenocarcinoma patients were eligible and included in the analysis. Overall survival was compared according to the three AJCC staging systems. For the three versions, the P value for the trend in overall survival was significant (P<0.0001). Cancer-specific Cox regression hazard was calculated for the three staging systems. Pairwise hazard ratio comparisons between different AJCC 6th stages were conducted and all P values for comparisons were significant (P<0.0001). Pairwise hazard ratio comparisons between different AJCC 7th and 8th stages were also performed, and all comparisons were significant (P<0.05) except for stage IIB vs. IIIA. C-statistic (using death from small intestinal adenocarcinoma as the dependent variable) for AJCC 6th staging system was: 0.645 [standard error (SE): 0.011; 95% CI: 0.623-0.668]; for c-statistic for AJCC 7th staging system was 0.658 (SE: 0.011; 95% CI: 0.637-0.680); while c-statistic for AJCC 8th staging system was 0.660 (SE: 0.011; 95% CI: 0.638-0.682). Multivariate analysis of factors affecting cancer-specific survival suggested that older age (P=0.005), higher lymph node ratio (P<0.0001) and duodenal localization of the primary are associated with worse outcomes (P=0.008). Conclusions There is no evidence that AJCC 8th system provided better prognostic characterization compared to previous AJCC staging systems for small intestinal adenocarcinoma. Subsite-specific staging paradigms should be explored in future editions of the staging system.

Abstract
This analysis aims to evaluate the performance characteristics of alternative baseline imaging thresholds in a cohort of hepatocellular carcinoma (HCC) patients from the Surveillance, Epidemiology, and End Results (SEER) database. HCC patients within the SEER database (2010-2015) who had complete information on clinical T and N stages as well as complete information on metastatic sites were eligible for the current study. Various performance characteristics associated with baseline imaging were investigated, including specificity, sensitivity, positive likelihood ratio (LR), negative LR, number needed to investigate (NNI), negative predictive value (NPV), positive predictive value (PPV), and accuracy. A total of 27,201 HCC patients were included. Based on current recommendations that advocate for the use of cross-sectional chest imaging in all newly diagnosed cases of HCC, these recommendations would yield a PPV of 5.0% for the detection of lung metastases. This would translate to an NNI of 20.0. When T1N0 patients were excluded from routine chest or bone imaging, this resulted in a PPV of 6.8% for the identification of lung metastases and an NNI of 14.7. Likewise, this translated to a PPV of 4.6% for the identification of bone metastases and an NNI of 21.7. Similarly, when patients with T1N0 disease and normal alpha-fetoprotein (AFP) were excluded from routine imaging, this resulted in a PPV of 5.6% for the identification of lung metastases and an NNI of 17.8. Also, this translated to a PPV of 3.8% for the identification of bone metastases and an NNI of 26.3. The current study suggests that the omission of routine baseline chest imaging may be considered in selected patients with asymptomatic early-stage HCC and normal AFP.

Abstract
BACKGROUND The current study evaluates the prognostic value of the 8th edition of the American Joint Committee on Cancer (AJCC) staging system for patients with anal carcinoma. PATIENTS AND METHODS The Surveillance, Epidemiology and End Results (SEER) database (2004-2014) was explored and AJCC 6th and 8th stages were formulated. Through Kaplan-Meier analysis, overall survival analyses were performed. The Cox regression model (adjusted for age, gender, histology, ethnicity, subsite and grade) was calculated for cancer-specific survival and, subsequently, pairwise comparisons of hazard ratios were calculated. RESULTS A total of 11,934 anal carcinoma patients were included in the analysis. Overall survival was compared according to both AJCC 6th and 8th systems. For both staging systems, the p value for the trend in overall survival was significant (p < .0001). Nevertheless, for the AJCC 6th system, stage IIIA and IIIB curves were overlapping; while for the AJCC 8th system, the median survival for stage IIB was lower than the mean survival for stage IIIA (74 months vs. 96 months). Moreover, stage IIIB and stage IIIC curves were overlapping. The cause-specific (cancer-specific) Cox regression hazard was calculated for both staging systems. Pairwise hazard ratio comparisons between different AJCC 6th stages were performed and all p values for comparisons were significant (p < .05). Pairwise hazard ratio comparisons between different AJCC 8th stages were performed and only the following comparisons were significant (p < .0001) (I vs. IIA; IIA vs. IIB; IIIC vs. IV). The C-statistic (using death from anal carcinoma as the dependent variable) for the AJCC 6th staging system was: 0.681 (SE: 0.009; 95% CI: 0.664-0.698); while the C-statistic for the AJCC 8th staging system was 0.687 (SE: 0.008; 95% CI: 0.670-0.703). CONCLUSIONS There is no evidence of significant improvement in the AJCC 8th edition compared to AJCC 6th (or 7th) edition in terms of overall or cancer-specific survival prediction.

Abstract
BACKGROUND & AIMS The association between case volume and outcomes is well-documented for several cancer types. However, it is unknown if patients with hepatocellular carcinoma treated at high-volume centres have improved overall survival. METHODS About 135 442 patients diagnosed with hepatocellular carcinoma between 2004-2014 were identified in the Commission on Cancer's National Cancer Database and 53 795 patients were excluded for metastatic or node-positive disease. Average annual case volume was calculated as the total number of cases treated per centre from 2004-2014 and dividing by 10. Receiver operating characteristic curves showed the most significant case number threshold between high-volume centres and remaining centres. Univariate and multivariate analyses were performed using Cox regression analysis to determine factors associated with improved survival. Kaplan-Meier curves and log-rank tests were used for overall survival estimates. RESULTS A total of 81 647 patients with stage I-III hepatocellular carcinoma were treated at a total of 1218 centres. The median [range] case volume per year averaged over the 10-year study period was 48.6 [0.1-205.5]. High-volume centres treated >114 cases of hepatocellular carcinoma annually while remaining centre treated ≤114 cases. Median survival for patients treated in high-volume centres and remaining centres were 31.9 and 16.6 months respectively (Log Rank P < .001). On multivariate analysis, average annual case volume was significantly associated with improved survival. CONCLUSIONS Receiving treatment at a high-volume centre is significantly associated with survival for patients with non-metastatic disease. Improved survival at high-volume centres may be related to access to a variety of treatment modalities, multidisciplinary evaluation, and/or subspecialty expertise.

Abstract
BACKGROUND The 8th edition of the American Joint Committee on Cancer (AJCC) staging system for pancreatic exocrine adenocarcinoma has been released. The current study seeks to assess the 7th and 8th editions among patients registered within the surveillance, epidemiology and end results (SEER) database. METHODS SEER database (2010-2013) has been accessed through SEER*Stat program and AJCC 8th edition stages were reconstructed utilizing the collaborative stage descriptions. Kaplan-Meier analysis of overall survival and pancreatic cancer-specific survival analyses (according to both 7th and 8th editions and according to whether pathological or clinical staging were conducted) has been performed. Multivariate analysis of factors affecting pancreatic cancer-specific survival was also conducted through a Cox proportional hazard model. RESULTS A total of 18 948 patients with pancreatic adenocarcinoma were identified in the period from 2010-2013. Pancreatic cancer-specific survival among pathologically staged patients and according to the 8th edition showed significant differences for all pair wise comparisons among different stages (P < 0.0001) except for the comparison between stage IA and stage IB (P = 0.307) and the comparison between stage IB and stage IIA (P = 0.116). Moreover, P value for stage IA vs IIA was 0.014; while pancreatic cancer-specific survival according to the 7th edition among pathologically staged patients showed significant differences for all pair wise comparisons among different stages (P < 0.0001) except for the comparison between IA and IB (P = 0.072), the comparison between stage IIA and stage IIB (P = 0.065), the comparison between stage IIA and stage III (P = 0.059) and the comparison between IIB and III (P = 0.595). Among clinically staged patients (i.e. those who did not undergo initial radical surgery), the prognostic performance of both 7th and 8th stages for both overall survival and pancreatic cancer-specific survival was limited. CONCLUSION There is clearly a need to have two staging systems for pancreatic adenocarcinoma: pathological and clinical staging systems.

Abstract
AIM To validate the changes among the American Joint Committee on Cancer (AJCC) eighth staging system for cutaneous melanoma. METHODOLOGY Surveillance, Epidemiology and End Results database (2004-2014) was queried. Kaplan-Meier survival estimates were evaluated according to both AJCC seventh and eighth systems. RESULTS Overall survival was assessed according to the two editions and p-values for overall trend were significant (p < 0.001) for all scenarios. Notably for pathologically staged patients, the mean survival for stage IIC was lower than that for stage IIIA and IIIB. Likewise, among clinically staged patients the mean survival for stage IIC was lower than that for stage III (these findings were identical among both editions). CONCLUSION AJCC eighth system holds comparable performance to AJCC seventh system.

RESULTS For gastric GISTs, concordance-index according to AJCC was 0.834; according to NIH was 0.833; according to AFIP was 0.836. Concordance-index for nongastric GISTs according to AJCC was 0.800, according to NIH was 0.801 and according to AFIP was 0.799. CONCLUSION The performance of the three models is comparable with regards to cancer-specific survival prediction.

Abstract
Aim: To assess the impact of the staging method on the utility of the American Joint Committee on Cancer (AJCC) system for non-small-cell lung cancer. Methods: Surveillance, Epidemiology and End Results database was accessed and cancer-specific survival analyses were conducted. Results: For cancer-specific survival among pathologically staged patients, p-values for all pair wise comparisons were significant, except for stage IIIB versus IIIC; while among clinically staged patients, p-values for all pair wise comparisons were significant, except for stage IIA versus IIB. Among pathologically staged patients, AJCC eighth c-statistic was 0.705; while among clinically staged patients, AJCC eighth c-statistic was 0.687. Conclusion: The discriminatory power of eighth AJCC for non-small-cell lung cancer is lower for clinically staged compared with pathologically staged patients.

Abstract
OBJECTIVES To validate the prognostic value of the new American Joint Committee on Cancer (AJCC) staging system (eighth edition) among different staging contexts (clinical vs. pathologic). METHODS Surveillance, Epidemiology, and End Results (SEER) database (2010-2014) was accessed through SEER*Stat program and both AJCC seventh and eighth edition stages were assigned for each patient. Overall and cancer-specific survival analyses according to both editions were conducted through Kaplan-Meier analysis. Concordance index (c-index) was assessed for each edition. RESULTS A total of 7074 patients with pathologically staged and 26,698 with clinically staged urinary bladder carcinoma were identified in the period from 2010 to 2014. Among patients with pathologically staged disease without neoadjuvant treatment, P values for all pairwise comparisons among different stages (according to AJCC seventh and eighth systems) were significant for both overall and cancer-specific survivals (< .01). Moreover, within the same cohort, c-index (using death from urinary bladder cancer as the dependent variable) for AJCC seventh system was 0.714 (SE 0.008; 95% CI, 0.699-0.729); whereas the c-index for the AJCC eighth system was 0.718 (SE 0.008; 95% CI, 0.702-0.733). Likewise, among patients with clinically staged disease, P values for all pairwise comparisons among different AJCC eighth stages were significant for overall survival (< .05) except for stage IIIA versus stage IIIB; whereas P values for all pairwise comparisons among different AJCC eighth stages were significant for cancer-specific survival (P < .05). CONCLUSION This analysis supports the prognostic relevance of the added substages described within AJCC eighth edition stages III and IV for clinically staged and pathologically staged disease without neoadjuvant treatment.

Prognostic Biomarker Identification Through Integrating the Gene Signatures of Hepatocellular Carcinoma Properties. EBioMedicine 2017; 19:18-30. [PMID: 28434945 PMCID: PMC5440601 DOI: 10.1016/j.ebiom.2017.04.014] [Citation(s) in RCA: 36] [Impact Index Per Article: 5.1] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2017] [Revised: 04/07/2017] [Accepted: 04/07/2017] [Indexed: 02/06/2023] Open
Abstract
Many molecular classification and prognostic gene signatures for hepatocellular carcinoma (HCC) patients have been established based on genome-wide gene expression profiling; however, their generalizability is unclear. Herein, we systematically assessed the prognostic effects of these gene signatures and identified valuable prognostic biomarkers by integrating these gene signatures. With two independent HCC datasets (GSE14520, N = 242 and GSE54236, N = 78), 30 published gene signatures were evaluated, and 11 were significantly associated with the overall survival (OS) of postoperative HCC patients in both datasets. The random survival forest models suggested that the gene signatures were superior to clinical characteristics for predicting the prognosis of the patients. Based on the 11 gene signatures, a functional protein-protein interaction (PPI) network with 1406 nodes and 10,135 edges was established. With tissue microarrays of HCC patients (N = 60), we determined the prognostic values of the core genes in the network and found that RAD21, CDK1, and HDAC2 expression levels were negatively associated with OS for HCC patients. The multivariate Cox regression analyses suggested that CDK1 was an independent prognostic factor, which was validated in an independent case cohort (N = 78). In cellular models, inhibition of CDK1 by siRNA or a specific inhibitor, RO-3306, reduced cellular proliferation and viability for HCC cells. These results suggest that the prognostic predictive capacities of these gene signatures are reproducible and that CDK1 is a potential prognostic biomarker or therapeutic target for HCC patients. Eleven gene signatures have promising values for the OS prediction of HCC patients who undergo the surgical treatments. Prediction results for the 11 gene signatures were in moderate concordance, and genes included were functionally linked. CDK1 is an independent prognostic biomarker and a potential therapeutic target for HCC patients.
Various gene signatures for hepatocellular carcinoma (HCC) patients have been reported; however, their generalizability is unclear. Using two HCC patient datasets, we assessed the prognostic values of these gene signatures and identified 11 gene signatures that were associated with overall survival for postoperative HCC patients in both cohorts. Genes derived from these signatures formed a functional protein-protein interaction network with 1,406 nodes and 10,135 edges, and the expression levels of three core genes, RAD21, CDK1, and HDAC2, in the network were negatively associated with the overall survival of HCC patients. Further studies suggested that CDK1 is an independent prognostic factor and that it is a potential therapeutic target for HCC patients.
