RESUMO

Child-Pugh (CP) grade A patients with early stage hepatocellular carcinoma (HCC) are candidates for curative surgery, while some patients still have a poor outcome. The aim of this study was to investigate the prognostic values of 2 new evaluation models for liver function, named albumin-bilirubin (ALBI) and platelet-albumin-bilirubin (PALBI) grades, in CP grade A patients with HCC.In this retrospective cohort study, we reviewed 134 cases of CP grade A patients with hepatitis B-associated HCC who underwent radical surgery. ALBI and PALBI grades were calculated based on preoperative serologic examinations. Overall survival (OS) and recurrence-free survival (RFS) were estimated by Kaplan-Meier curve and Cox regression. The prognostic performances of the models were estimated by using the concordance index (C-index).During a median follow-up time of 27 months, 27.6% (37/134) of patients died and 26.1% (35/134) experienced recurrence. Kaplan-Meier analyses showed that ALBI and PALBI grades were significantly associated with OS and RFS. Multivariate analyses further revealed that both ALBI and PALBI grades were independent predictors for survival. Furthermore, the prognostic values of the combination of tumor size with ALBI (C-index = 0.754, 95% confidence interval [CI]: 0.675-0.849) or with PALBI (C-index = 0.762, 95% CI: 0.664-0.844) may be comparable with both Barcelona Clinic Liver Cancer and Cancer of Liver Italian Program staging systems.The ALBI and PALBI grades, in particular the combination with tumor size, are effective models for discriminating survival in CP grade A patients with HCC.

RESUMO

Combined hepatocellular-cholangiocarcinoma (CHCC) is a rare type of primary liver cancer (PLC). The aim of this study was to investigate the disease characteristics in CHCC patients and compare them with those in hepatocellular carcinoma (HCC) or intrahepatic cholangiocarcinoma (ICC).The perioperative and follow-up data of CHCC patients (n = 15), HCC patients (n = 577), and ICC patients (n = 61) were retrospectively analyzed, and the clinicopathological characteristics were compared among these 3 groups.In the CHCC group, the serum level of AFP was significantly higher than that of the ICC group (P = .002), and the CA19-9 level was higher than that of the HCC group (P = .011). The positive rates of CK7 and CK19 expression were higher in CHCC group than in HCC group (both P < .001), while the positive rates of Glypican-3 and Hepatocyte expression were higher in CHCC group than in ICC group (both P < .001). Meanwhile, the CHCC patients were likely to have undergone more MJH/LT than the HCC patients (P = .037) and the ICC patients (P = .011). Macrovascular invasion and lymph node metastasis in the CHCC group were significantly higher but satellite lesions were similar, compared to the HCC group. Both the 1-year disease-free survival (DFS) and the 1-year overall survival (OS) for the CHCC patients were worse than those for the HCC patients. AFP ≥ 400 ng/ml, tumor size ≥5 cm, tumor number ≥2, macro- and microvascular invasion, distant metastasis and positive margin were risk factors for both DFS and OS for the PLC patients. Multivariate analysis also confirmed that ICC and lymph node metastasis were risk factors for DFS and MJH/LT was risk factor for OS.CHCC patients appear to have intermediate clinical characteristics in comparison with the HCC and ICC patients, and the 1-year DFS and OS for the CHCC patients was worse than the HCC patients, but similar to the ICC patients.

RESUMO

The complete resection offers the best long-term survival for advanced hepatocellular carcinoma patients. ALPPS as a choice of resection, how is its outcome compared to one-stage resection, liver transplantation and TACE? This retrospective study included 20 ALPPS patients. To minimize the effect of confounding influences of measured covariates, PSM was performed. The overall survival (OS), morbidity, mortality and the increasing rate, KGR were analyzed. The OS in ALPPS group is 27.4 (±3.8 months) moths and the TACE group is 13.5(±1.2 months) (P < .001), LT group is 41.3 (±3.2 months) (P = .048), Resection group is 31.8 (±2.6 months) (P = .368). And the medium increasing volume is 209.5 cm (±61.5 cm) with the increasing ratio 52.4% (+26.9%). The ALPPS is a feasible treatment for HCC patients and it provides a better long-term survival than TACE and it is similar to Resection, less than LT.

RESUMO

BACKGROUND: Long non-coding RNA colon cancer-associated transcript 2 (CCAT2) is a 1752-bp lncRNA transcribed from m8q24 genomic region. A lot of investigations have confirmed the involvement of CCAT2 in the tumorigenesis of many cancer types. Previous studies found that over-expression of CCAT2 significantly promoted cell migration and proliferation, and inhibited apoptosis of HCC cells. In the present investigation, the clinical value and prognostic significance of CCAT2 were investigated. METHODS: The 122 pairs of HCC tissues and adjacent normal liver tissues were acquired between September 2013 and February 2018. The expression levels of CCAT2 in HCC tissues and their corresponding adjacent normal liver tissues were examined by RT-qPCR analysis. Survival was calculated using the Kaplan-Meier method and analyzed using the log-rank test. Independent prognostic indicators were determined in the multivariate analysis using Cox's proportional hazard model. RESULTS: CCAT2 expression levels were significantly increased in HCC tissues compared to that in their normal counterparts (P < .001). CCAT2 expression was significantly correlated with vascular invasion (P = .001), histopathologic grading (P = .001), distant metastasis (P = .002) and TNM stage (P = .018). A Kaplan-Meier survival curve showed that the overall survival rate of HCC patients in high CCAT2 expression group markedly decreased as compared with that of low CCAT2 expression group (P = .016). In addition, COX multivariate analysis showed that high expression of CCAT2 was an independent risk factor for predicting shorter overall survival time in HCC (HR = 2.126, 95%CI:1.273-8.775, P = .021). CONCLUSIONS: Taken together, this research revealed that lncRNA CCAT2 may serve as a potential biomarker for predicting overall survival time in HCC.

RESUMO

BACKGROUND/AIM: Diabetes mellitus (DM) is known as an important risk factor for hepatocellular carcinoma (HCC). However, surgical outcomes in patients with DM and HCC have not been evaluated in detail. PATIENTS AND METHODS: We retrospectively studied 177 patients with type 2 DM who underwent curative hepatectomy for HCC. Surgical outcomes after curative hepatectomy and prognostic factors were evaluated among 75 patients with DM and/or nonalcoholic steatohepatitis (NASH)-related HCC and 102 patients with DM and viral or alcoholic hepatitis (VAH)-related HCC. RESULTS: The 5-year survival rate and 5-year recurrence-free survival rate were significantly higher in the DM and/or NASH-related HCC group (87% and 51%) than in the DM and VAH-related HCC group (68%: p=0.0001 and 26%: p=0.0002). Multivariate analysis showed DM and/or NASH-related HCC to be significant independent prognostic factors for overall survival and recurrence-free survival. CONCLUSION: Patients with DM and/or NASH-related HCC showed more favorable surgical outcomes after hepatectomy in patients with DM and HCC.

RESUMO

BACKGROUND: Factors associated with response to lenvatinib have not been clarified in patients with hepatocellular carcinoma (HCC). PATIENTS AND METHODS: This study retrospectively analyzed 50 patients treated with lenvatinib as first-line therapy between March 2018 and March 2019. Patients were divided into two groups by the Modified Response Evaluation Criteria in Solid Tumours (mRECIST) (responders and non-responders, whose best overall responses were complete (CR)/partial response (PR) and stable (SD)/progressive disease (PD), respectively). Factors associated with response were assessed, including the relative dose intensity 8 weeks after lenvatinib induction (8W-RDI). RESULTS: The best overall responses were 0/22/14/14 of CR/PR/SD/PD. Multivariate analysis revealed that only 8W-RDI was significantly associated with response. The receiver operating characteristic curve for 8W-RDI in differentiating responders from non-responders revealed a cut-off value of 75%. Patients with 8W-RDI ≥75% experienced a higher response rate and longer progression-free survival than patients with 8W-RDI <75%. CONCLUSION: Our results suggest that maintaining an RDI ≥75% during the initial 8 weeks of lenvatinib treatment has a favorable impact on response.

RESUMO

PURPOSE: To investigate the prognostic value of 17 platelet-based prognostic scores in patients with malignant hepatic tumors after TACE therapy. METHODS: In total, 92 patients were divided into death group and survival group according to long-term follow-up results. The AUC was calculated to determine the optimal cut-off values for predicting prognosis. To determine better prognostic models, platelet-based models were analyzed separately after being showed as binary according to cut-off values. Cumulative survival rates of malignant hepatic tumors were calculated using Kaplan-Meier curves and differences were analyzed by the log-rank test. Univariate and multivariate analyses were performed to identify platelet-based prognostic scores associated with overall survival. RESULTS: Univariate analysis showed that APGA, APRI, FIB-4, FibroQ, GUCI, King's score, Lok index, PAPAS, cirrhosis, number of tumors, vascular cancer embolus, AFP, ALP and APTT were significantly related to prognosis. A multivariate analysis showed that the APGA, number of tumors, ALP and APTT were independently associated with overall survival. CONCLUSION: This study showed that the APGA, a platelet-based prognostic score, was an independent marker of prognosis in patients with malignant hepatic tumors after TACE and was superior to the other platelet-based prognostic scores in terms of prognostic ability.

RESUMO

Poor outcomes of hepatocellular carcinomas (HCC) in chronic kidney disease (CKD) patients are well described. Transarterial therapy is the standard treatment for HCC, following which regular contrast-enhanced imaging for residual disease is recommended. CKD is considered a relative contraindication for transarterial therapy owing to renal failure.This retrospective study investigated the outcomes of transarterial therapy in HCC patients with CKD. In total, 132 HCC patients who received transarterial therapy were enrolled, of whom 36 had CKD. Most CKD patients were elderly, with mean age of diagnosis of 69.7 ±â€Š11.4 years. Hypertension (odds ratio [OR]; 5.06; 95% confidence interval [Cl]; 1.83-13.94), hepatitis C virus carrier rate (OR; 4.12, 95% CI; 1.13-14.99) and diabetes (OR; 3.62, 95% CI; 1.22-10.72) were significant predictors for CKD in HCC patients. Post therapy, the estimated glomerular filtration rate significantly decreased 13.7% from baseline in the CKD patients (P = .03). There were more post-therapy complications than in the non-CKD group, e.g. acute renal failure and sepsis (P < .01 vs P < .01). Overall survival in the CKD group was significantly poor (10.9 ±â€Š8.5 vs 23.5 ±â€Š16.3 months, P < .01).The lower survival of CKD patients was unrelated to treatment modality or less contrast-enhanced imaging follow-up. Further research on patient care and factors leading to poor outcomes for CKD is needed.

RESUMO

BACKGROUND/AIM: To evaluate the impact of DEPDC1 expression on patient prognosis after hepatic resection for hepatocellular carcinoma (HCC). PATIENTS AND METHODS: We reviewed data from 75 patients who underwent hepatic resection for HCC between 2004 and 2013. Recurrence at 2 years following resection, which mainly included metastatic recurrence, was defined as late recurrence. RESULTS: DEPDC1 was up-regulated in HCC tissue and in non-tumor tissue of patients with HCC compared to normal liver (p<0.01 and p<0.01, respectively). High expression of DEPDC1 was associated with poor overall, disease-specific, and disease-free survival (p=0.02, p<0.01, and p<0.01, respectively). High DEPDC1 expression was an independent predictor of death and recurrence (p=0.03 and p<0.01, respectively). High expression of DEPDC1 in non-tumor liver was an independent risk factor for late recurrence (p=0.04). CONCLUSION: High expression of DEPDC1 in tumor tissue appears to be associated with tumor progression and poor prognosis.

RESUMO

To compare the efficacy of drug-eluting bead transarterial chemoembolization combined with radiofrequency ablation (DEB-TACE+RFA) versus DEB-TACE alone in Chinese hepatocellular carcinoma (HCC) patients.The 28 patients receiving DEB-TACE+RFA and 74 HCC patients receiving DEB-TACE were recruited in this study. Treatment responses, progression-free survival (PFS), and overall survival (OS) were evaluated.One to 3 months after treatments, the proportion of patients achieving complete response (CR) (78.6% vs 33.8%, P <.001) and objective response rate (ORR) (92.9% vs 78.4%, P =.010) were elevated in DEB-TACE+RFA group compared with DEB-TACE group. Multivariate logistic regression displayed that DEB-TACE+RFA was an independently predicting factor for better CR (P = .006). Subgroup analysis of CR achievement illuminated that DEB-TACE+RFA disclosed better CR achievement in patients with history of cirrhosis (P <.001), tumor located in right liver (P = .003), bilobar disease (P = .013), tumor size <3.3 cm (P = .001), no portal vein invasion (P = .001), no hepatic vein invasion (P <.001), Child-pugh stage A (P <.001), Barcelona Clinic Liver Cancer (BCLC) stage 0, A-B (P <.001), abnormal alpha-fetoprotein (AFP) (P = .001) and normal AFP (P = .016). The PFSs were similar between 2 groups (P = .112), however, the OS was more prolonged in DEB-TACE+RFA group (P = .025) compared with DEB-TACE group. And subgroup analysis displayed that PFS of patients with largest nodule size >3.3 cm (P = .025) was longer and patients with unilobar disease (P = .009), and patients with no hepatic invasion (P = .019) and Child-pugh stage A (P = .037) had more favorable OS in DEB-TACE+RFA group compared with DEB-TACE group.DEB-TACE+RFA achieved better treatment responses and OS compared with DEB-TACE alone in Chinese HCC patients.

RESUMO

Heme oxygenase-1 (HO-1) is an important catalytic enzyme in heme degradation, which increases during stressful conditions. It plays a major role in antioxidative and antiapoptotic processes and is associated with tumor growth and metastasis.This study aimed to evaluate the degree of HO-1 expressions in hepatocellular carcinoma (HCC) surgical specimens and the correlation between HO-1 expression and patient prognosis. Formalin-fixed, paraffin-embedded HCC tissue samples (n = 96) were included in the analysis, and the expression of HO-1 was evaluated by immunohistochemical staining. We reviewed clinical features of patients and evaluated the prognostic role of HO-1 in patient survival and recurrence.Positive HO-1 expression was identified in 43 cases (44.8%) and was frequently found in patients with advanced histology (Edmondson-Steiner [E-S] grade 2, 3, 4), α-fetoprotein (AFP) level of more than 200 IU/mL, and the presence of microvascular and capsular invasion (P < .05). In the univariate analysis, the overall survival (OS) and disease-free survival (DFS) of patients with HO-1-positive HCC were not statistically different from those with HO-1-negative HCC. Moreover, HO-1 expression was not associated with patient survival and recurrence based on the multivariate analysis. In the subgroup analysis of patients without preoperative transarterial chemoembolization (TACE) (n = 61), HO-1 was not also associated with tumor recurrence (P = .681).The clinical implication of HO-1 activity is controversial in various malignancies. However, HO-1 expression did not seem to influence the prognosis of HCC patients.

RESUMO

To discuss the prognostic correlation between hepatitis B virus DNA (HBV DNA) level and HBV-related hepatocellular carcinoma (HCC) patients with microvascular invasion (MVI).Data from HCC patients undergoing hepatectomy with pathological evidence of MVI were retrospectively collected and 1:1 propensity scoring matching (PSM) analysis was performed. According to the HBV DNA levels before and after surgery, the disease-free survival (DFS) and overall survival (OS) were evaluated using the Kaplan-Meier method, and the Cox proportional hazards regression was used to analyze the risk factors associated with the postoperative prognosis. After 1:1 PSM, 139 pairs of patients were enrolled in the high preoperative HBV DNA level group (H group) and low preoperative HBV DNA level group (L group), and after operation, patients with high preoperative HBV DNA levels were divided into the persistently high HBV DNA level group (P group) and the decreased HBV DNA level group (D group).According to the multivariate analysis, the HBV DNA level of 2000 IU/ml or greater before operation was significantly associated with the DFS (hazard ratio, 1.322; 95%CI, 1.016-1.721) and OS (hazard ratio, 1.390; 95%CI, 1.023-1.888). A persistent HBV DNA level of 2,000 IU/ml or greater after operation was also the independent risk factor of DFS (hazard ratio, 1.421; 95%CI, 1.018-1.984) and OS (hazard ratio, 1.545; 95%CI, 1.076-2.219).For the HBV-related HCC patients with MVI, preoperative high HBV DNA copies are prognostication of poorer prognosis, and effective antivirus treatment would significantly improve the patients' prognosis.

RESUMO

The aim of the present study is to construct a competitive endogenous RNA (ceRNA) regulatory network by using differentially expressed long noncoding RNAs (lncRNAs), microRNAs (miRNAs), and mRNAs in patients with hepatocellular carcinoma (HCC), and to construct a prognostic model for predicting overall survival (OS) of HCC patients. Differentially expressed lncRNAs, miRNAs, and mRNAs were explored between HCC tissues and normal liver tissues. A prognostic model was built for predicting OS of HCC patients and receiver operating characteristic curves were used to evaluate the performance of the prognostic model. There were 455 differentially expressed lncRNAs, 181 differentially expressed miRNAs, and 5035 differentially expressed mRNAs. A ceRNA regulatory network was constructed based on 43 lncRNAs, 37 miRNAs, and 105 mRNAs. Eight mRNA biomarkers (H2AFX, SQSTM1, ITM2A, PFKP, TPD52L1, ACSL4, STRN3, and CPEB3) were identified as independent risk factors by multivariate Cox regression and were used to develop a prognostic model for OS. The C-indexes in the model group were 0.776 (95% confidence interval [CI], 0.730-0.822), 0.745 (95% CI, 0.699-0.791), and 0.789 (95% CI, 0.743-0.835) for 1-, 3-, and 5-year OS, respectively. The current study revealed potential molecular biological regulation pathways and prognostic biomarkers by the ceRNA regulatory network. A prognostic model based on prognostic mRNAs in the ceRNA network might be helpful to predict the individual mortality risk for HCC patients.

RESUMO

We evaluated the post-treatment overall survival (OS) of elderly hepatocellular carcinoma (HCC) patients.The archived records of 10,578 HCC patients registered at the Korean Central Cancer Registry from 2008 through 2014 were retrospectively analyzed. In this registry, we selected Barcelona Clinic Liver Cancer (BCLC) 0, A, or B staged HCC patients (n = 4744) treated by surgical resection (SR), local ablation therapy (LAT), or locoregional therapy (LRT). OSs in nonelderly (<70 years) and elderly (≥70 years) patients were compared after propensity score matching (PSM).In BCLC 0-A staged HCC, the cumulative OS rates of elderly patients were poorer than those of nonelderly patients after PSM (P < .001), but not in those with BCLC stage B (P > .05). In BCLC 0-A staged elderly patients, OS after SR was significantly better than after LAT (P = .005) or LRT (P < .001). In BCLC B staged elderly patients, SR achieved better OS than LRT (P = .006). Multivariable analysis showed that LAT (hazard ratio [HR] 1.52, P = .048) or LRT (HR, 2.01, P < .001) as compared with SR, and large (>3 cm) tumor size (HR1.49, P = .018) were poor predictors of OS for elderly patients with BCLC stage 0-A, and that LRT (HR, 2.64, P = .042) was a poor predictor for those with BCLC stage B.SR provided a better OS rate than LAT or LRT in elderly HCC patients with BCLC stage 0-A, than LRT in those with BCLC stage B. SR should be considered the first therapeutic option even in elderly HCC patients with these stages.

RESUMO

Accumulating evidence has suggested that microRNAs play important roles in the development of hepatocellular carcinoma (HCC) and are involved in drug resistance. miR-21-5p was overexpressed in a variety of cancers and promoted the tumorigenesis; however, the function of miR-21-5p in HCC still remains unknown. In this study, our results showed that miR-21-5p was highly expressed in HCC tissues and cell lines. Notably, the level of miR-21-5p was relatively higher in cisplatin (DDP)-resistant HCC patients. Overexpression of miR-21-5p attenuated the inhibitory effect of DDP on the proliferation and apoptosis of HCC cells. Mechanistically, the luciferase report assay-identified FAS ligand (FASLG) was a direct target of miR-21-5p. Overexpression of miR-21-5p decreased both the mRNA and protein levels of FASLG in HCC cells. FASLG was downregulated in HCC tissues and was significantly negatively correlated with the expression of miR-21-5p. Restoring the expression of FASLG upregulated the chemosensitivity of HCC cells expressing miR-21-5p. In conclusion, our results demonstrated that miR-21-5p targeted FASLG and suppressed the sensitivity of HCC cells to DDP treatment.

RESUMO

BACKGROUND/AIM: Treatment algorithms for primary and recurrent hepatocellular carcinoma (HCC) are described in the current Japanese Clinical Practice Guidelines; however, primary and recurrent tumors exhibit several differences in oncological characteristics such as clinicopathological features and prognostic factors. This study aimed to investigate the prognostic factors for recurrent HCC including time of recurrence after primary hepatectomy, to elucidate appropriate treatment strategies in these patients. PATIENTS AND METHODS: One hundred and nine patients who had undergone radical resection of primary HCC at our Hospital and had experienced intrahepatic recurrence were included in this study. Patients were categorized into the early-recurrence (ER, <1 year postoperatively) or the late-recurrence (LR, ≥1 year postoperatively) groups. Clinicopathological features were compared between the two groups for prognostic analyses. RESULTS: Comparison of clinicopathological features between the ER and LR groups revealed that, at the time of recurrence, the ER group had a significantly higher frequency of multiple recurrences compared to the LR group. In univariate prognostic analysis, the time of recurrence (ER or LR) and the number of recurrent tumors (≥3) were significant prognostic factors after recurrence. Multivariate analysis revealed that three or more recurrent tumors and ER were independent prognostic factors for poor survival after recurrence. CONCLUSION: HCC is likely to recur, and the characteristics of recurrent HCC are distinct from those of primary HCC. To improve post-recurrence poor prognosis, new and more feasible algorithms, such as aggressive surgical treatment for cases with less than three recurrent tumors, which were revealed in the current study, are needed.

RESUMO

BACKGROUND: Increasing evidence has shown that long non-coding RNAs (lncRNAs) are important in hepatocellular carcinoma (HCC) development and progression. In this study, we aim to evaluate the expression of lncRNA FAM99B and its biological function in HCC. METHODS: The expression level of FAM99B in HCC was assessed based on data from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO), verified using quantitative real-time polymerase chain reaction (qRT-PCR). HCCLM3 was transfected with lentivirus containing full-length FAM99B to obtain stable overexpressing cell line. Cell Counting Kit 8, clone formation, and transwell assays were used to investigate the effects of FAM99B in HCC progression. In addition, Gene Ontology, Kyoto Encyclopedia of Genes and Genomes, and PANTHER pathway analyses were conducted to investigate the underlying molecular mechanisms. RESULTS: FAM99B was found to be downregulated in HCC tissues compared with adjacent normal tissues based on TCGA, GEO, and qRT-PCR data. Our results revealed that downregulated FAM99B was significantly associated with vascular invasion, advanced histologic grade, and T stage. Kaplan-Meier analysis using TCGA data indicated that decreased FAM99B levels were significantly associated with poor overall survival in patients with HCC. Moreover, overexpression of FAM99B significantly inhibited cell proliferation, migration, and invasion in vitro. Pathway analyses showed that the co-expressed genes of FAM99B mainly participated in the pathways "Metabolic pathways" and "Blood coagulation". CONCLUSION: Our results suggest that FAM99B may serve as a tumor suppressor in HCC and may provide a promising therapy target for patients with HCC.

RESUMO

Plasmacytoid dendritic cells (pDCs) are present in various primary and metastatic human neoplasms; however, their clinical significance in hepatocellular carcinoma (HCC) is unclear. In this study, we investigated the distribution, prognostic value, and potential function of pDCs in HCC patients undergoing curative resection. We performed immunohistochemical analyses of whole tumor sections from 224 patients to assess the expression of BDCA2, CD3, CD4, CD8, Foxp3, granzyme B, IL-17, and CD34. The findings were validated using tissue microarrays from another two independent cohorts totaling 841 HCC patients undergoing curative resection. Our results demonstrated that high numbers of BDCA2+ pDCs within tumors correlated with high alpha-fetoprotein levels, greater vascular invasion, advanced tumor-node-metastasis stage, shorter overall survival, and a higher recurrence rate. However, patient outcomes were not associated with pDCs in peritumoral stromal or nontumor tissues. Furthermore, an increase in intratumoral pDCs was associated with increased intratumoral infiltration of Foxp3+ regulatory T cells and IL-17-producing cells and correlated with tumor vascular density. Univariate and multivariate analyses revealed that the presence of intratumoral pDCs alone or in combination with regulatory T and/or IL-17-producing cells was an independent predictor of time to recurrence and overall survival. In conclusion, our study demonstrated that intratumoral infiltration by pDCs is a novel indicator for poor prognosis in patients with HCC, possibly through the induction of an immune tolerogenic and inflammatory tumor microenvironment comprising regulatory T and IL-17-producing cells. An assessment of the combination of these cells represents a superior predictor of patient outcome.

RESUMO

BACKGROUND: Exosomes contain proteins, lipids, and biological molecules such as DNA and RNA. Nucleic acids in exosomes are a group of molecules that can act as biomarkers. Currently, there are many reports on exosomal microRNAs, which are ideal biomarkers for the early diagnosis of cancer. However, there are few reports on the role of exosomal microRNAs in the diagnosis and prognosis of hepatocellular carcinoma (HCC). AIM: To understand the mechanism of exosomal microRNA-224 (miR-224) in the development of HCC and evaluate its diagnostic and prognostic value. METHODS: Cell culture and transfection of exosomal miRNA-224, real-time quantitative PCR, luciferase reporter assay, and other methods were used to find new biomarkers related to the development of HCC that can be used to diagnose HCC and predict HCC prognosis. RESULTS: By targeting glycine N-methyltransferase, incubating exosomes with miR-224 mimic resulted in a significant increase in cell proliferation compared to that of the control group, while incubation with the miR-224 inhibitor significantly reduced cell proliferation. The same results were obtained for the cell invasion assay. Serum exosomal miR-224 did have some ability to differentiate patients with HCC from healthy controls, with an area under the curve of 0.910, and HCC patients with higher serum exosomal miR-224 expression had lower overall survival. CONCLUSION: Exosomal miR-224 is a tumor promotor and can be a marker of diagnosis and prognosis of HCC patients, however, its ability to distinguish liver diseases needs further verification.
