RESUMEN

BACKGROUND: We developed laparoscopic transfistulous bile duct exploration (LTBDE) for Mirizzi syndrome (MS) McSherry type II in September 2011. Then, single-incision LTBDE (SILTBDE) was adopted as a preferred technique since August 2013. This retrospective study aims to analyze the outcome of LTBDE in 7.7 years and to compare SILTBDE with four-incision LTBDE (4ILTBDE). METHODS: Seventeen consecutive patients underwent LTBDE for MS McSherry type II from September 2011 to May 2019. Transfistulous removal of the impacted stone(s), choledochoscopic bile duct exploration, and primary closure of the gallbladder remnant were performed without biliary drainage. RESULTS: The sex ratio is 12:5 (male: female) with an average age of 39.4 ± 10.3 (24-56) years. Ten patients (58.8%) had their diagnoses of MS established by preoperative imaging. According to the Csendes classification, three type II (17.6%), nine type III (52.9%), and five type IV (29.4%) were identified. The operative time was 264.8 ± 60.3 min (156-358 min). The stone clearance rate was 100%. The postoperative hospital stay was 4.7 ± 1.9 (2-10) days. No procedure was converted to an open operation. Two postoperative transient hyperamylasemia (11.8%) and one superficial wound infection (5.9%) occurred and all recovered well under conservative treatment (Clavien-Dindo grade I). During an average 2.2-year follow-up period, no biliary stricture or stone recurrence occurred. No significant difference exists between the SILTBDE and 4ILTBDE groups. Nevertheless, an insignificant trend of shorter postoperative hospital stay was observed in the former. A diagnosis of MS Csendes type IV implicates prolonged total and postoperative hospital stays (p < 0.01). CONCLUSIONS: LTBDE is safe and efficacious for MS McSherry type II. It provides a simple solution for various types of MS and avoids undesirable complications following bilioenteric anastomosis. SILTBDE is comparable to 4ILTBDE for selected patients. Patients with MS Csendes type IV need more time to recover after surgery.

RESUMEN

Regorafenib is a multikinase inhibitor that was approved by the US Food and Drug administration in 2017. Cancer stem cells (CSCs) are a small subset of cancer-initiating cells that are thought to contribute to therapeutic resistance. The forkhead box protein M1 (FOXM1) plays an important role in the regulation of the stemness of CSCs and mediates resistance to chemotherapy. However, the relationship between FOXM1 and regorafenib resistance in liver cancer cells remains unknown. We found that regorafenib-resistant HepG2 clones overexpressed FOXM1 and various markers of CSCs. Patients with hepatocellular carcinoma also exhibited an upregulation of FOXM1 and resistance to regorafenib, which were correlated with a poor survival rate. We identified a close relationship between FOXM1 expression and regorafenib resistance, which was correlated with the survival of patients with hepatocellular carcinoma. Thus, a strategy that antagonizes FOXM1-CD44 signaling would enhance the therapeutic efficacy of regorafenib in these patients.

RESUMEN

BACKGROUND: The implementation of an automated nucleic acid extraction system has many advantages over the manual methods. The purpose of this study was to evaluate the validity of two different methods for nucleic acid extraction in virus transport medium. METHODS: We collected 20 nasopharyngeal swabs in viral transport medium from the emergency department of the Asia University Hospital for the detection of SARS-CoV-2. The performance of the MaelstromTM 8 (Taiwan Advanced Nanotech) and the QIAamp Viral RNA Mini Kit (Qiagen) were compared for the extraction of nucleic acid from viral transport medium. The extracts were used for the validation of the RNA extraction procedures. The RNase P target was amplified in a one-step reverse transcription-quantitative PCR (RT-qPCR) reaction, as internal control for the extraction method. RESULTS: In this study, the agreement between the two methods was good and Pearson's correlation coefficient (r) was 0.919 (p < 0.001). The mean cycle threshold value of the two methods was 29.1. CONCLUSIONS: Overall, the performance values of the MaelstromTM 8 and the QIAamp Viral RNA Mini Kit were comparable to each other. In summary, the MaelstromTM 8 provides a standardized procedure, avoidance of sample-to-sample cross contaminations, is easy to use, improves turnaround time and requires less hands-on time as compared to the manual extraction method. The MaelstromTM 8 is more suitable for clinical laboratories that carry small or medium-sized samples for nucleic acid extraction.

RESUMEN

BACKGROUND: The objective of this study was to compare the validity of two different assays for the detection of SARS-CoV-2. METHODS: We collected 50 nasopharyngeal swabs in universal transport medium from the emergency department of Asia University Hospital for the detection of SARS-CoV-2 using reverse transcription-polymerase chain reaction (RT-PCR). The samples for the Liat SARS-CoV-2 influenza A/B test were stored at -70℃ after SARS-CoV-2 testing using the RT-PCR in order to assess method comparison. RESULTS: In this study, the Limit of detection (LOD) of the cobas Liat SARS-CoV-2 and influenza A/B nucleic acid test is 12 copies/µL and the assay obtained 100% positive agreement and negative percent agreement with RT-PCR. CONCLUSIONS: In summary, a prefect agreement exists between the detection of SARS-CoV-2 conducted with the cobas Liat SARS-CoV-2 and influenza A/B nucleic acid test and the RT-PCR. The cobas Liat SARS-CoV-2 and influenza A/B nucleic acid test is a reliable method for the detection of SARS-CoV-2, and it only requires 20 minutes to obtain the results. On the other hand, the cobas Liat SARS-CoV-2 and influenza A/B nucleic acid test is accurate, easy to use, and provides a faster turnaround time than testing performed in the high-throughput platform.

RESUMEN

Imbalance of lipid metabolism is a main cause of metabolic syndrome leading to life-threatening metabolic diseases. Angiopoietin-like protein 8 (Angptl8) was recently identified as a liver and adipose tissue-released hormone that is one of the molecules involved in triglyceride metabolism. However, the regulatory mechanism of Angptl8 is largely unknown. A high fat diet (HFD)-fed mouse model, which showed high cholesterol, high triglyceride, and high insulin in the blood, revealed the upregulation of hepatic and plasma Angptl8 and the downregulation of hepatic glycine N-methyltransferase (GNMT). The inverse correlation of hepatic Angptl8 and GNMT expression in the livers of HFD-fed mice was also confirmed in a publicly available microarray dataset. The mechanistic study using primary hepatocytes showed that the Angptl8 expression could be induced by insulin treatment in a dose- and time-dependent manner. Inhibition of PI3K/Akt pathway by the specific inhibitors or the dominant-negative Akt blocked the insulin-induced Angptl8 expression. Moreover, knockout of GNMT promoted the Akt activation as well as the Angptl8 expression. These results suggested that GNMT might be involved in insulin-induced Angptl8 expression in HFD-mediated metabolic syndrome.

RESUMEN

AIM: This paper aims to describe an intracorporeal tourniquet method for laparoscopic Pringle maneuver (PM). METHODS: One shortened Foley tube with side-hole on the tip was put into the abdomen. Then, the tail was pulled out through the side-hole to make a loop to encircle porta hepatis for inflow control. RESULT: It is easy to keep the tension by a metallic clip, and when released, the clip can be removed and the loop loosened. CONCLUSION: Therefore, PM could be performed inside the abdomen without special instrument nor extra trocar port. The intracorporeal Pringle maneuver with Huang's loop could be routinely used during laparoscopic liver resection even for a laparoscopic beginner because it is so easily learnt, safe, and effective.

RESUMEN

Hepatic cellular cancer (HCC) is one of the most common cancers in the world, which is a serious threat to human health and life quality. More than 700,000 people die of HCC each year on average, and its incidence increases in many countries. Chronic hepatitis B virus (HBV) infection has been identified as a dominant risk factor for HCC. The pathogenesis of HBV-induced hepatocarcinogenesis is, however, incompletely understood. Evidence currently available supports a key role of the HBV X protein (HBx) in the cancer transformation and malignant tumor metastasis. HBx is a multifunctional regulator that may cooperate with the host factors to exert its effects on transcription, signal transduction, cell cycle progression, apoptosis, protein degradation, expression of oncogene and anti-oncogene. This review presents the current knowledge in the molecular pathogenesis of HBx in the induction of HCC.

RESUMEN

Estrogen-related receptor alpha (ERRα) plays an important role in the development of hormone-dependent cancers, but its roles in lung cancer remain elusive. The present study was aimed to investigate the effects of ERRα on the proliferation and metastasis of lung cancer A549 cells. The mRNA and protein levels of ERRα were detected in lung cancer A549 and MCF-7 cells and bronchial epithelial BEAS-2B cells by qRT-PCR and Western blotting, respectively. ERRα plasmid transfection and XCT-790 (an inverse agonist of ERRα) were used to up-regulate or down-regulate ERRα expression in A549 cells, respectively. The viability of A549 cells was measured by cell counting kit-8 (CCK-8) and the motility of A549 cells by wound healing assay and Transwell migration/invasion assay. The epithelial markers E-cadherin (E-Cad) and zona occludin-1 (ZO-1), the mesenchymal markers fibronectin (FN) and vimentin (Vim) and the transcription factors (Snail, Zeb1 Twist and Slug) were further detected at mRNA and protein levels by qRT-PCR and Western blotting, respectively. The results showed that ERRα promoted the growth of lung cancer A549 cells in vitro. XCT-790 significantly inhibited the migration and invasion of A549 cells. Over-expression of ERRα promoted the epithelial-to-mesenchymal transition (EMT) of A549 cells, down-regulated the epithelial makers E-Cad and ZO-1, and up-regulated the mesenchymal makers FN and Vim. Silencing of Slug, but not other transcription factors, significantly abolished the ERRα-induced EMT of A549 cells. It was suggested that ERRα promoted the migration and invasion of A549 cells by inducing EMT, and Slug was involved in the process. Targeting ERRα might be an efficient approach for lung cancer treatment.

RESUMEN

Cancer and depression are closely interrelated, particularly in patients with advanced cancer, who often present with comorbid anxiety and depression for various reasons. Recently, there has been a growing interest in the study of depression in cancer patients, with the aim of assessing the possible triggers, predictors, adverse events, and possible treatment options for depression in several common cancers. The objective of this narrative review is to synthesize the extant literature on the relationship between the occurrence and progression of depression in several common patient categories. The authors conducted a comprehensive review of 75 articles published in PubMed over the past five years. This review was further evaluated in the present paper. Ultimately, it was determined that depression is a prevalent and detrimental phenomenon among cancer patients, particularly those with advanced disease. Consequently, there is a pressing need to prioritize research and interventions aimed at improving the quality of life and psychosocial well-being of cancer patients, including those with advanced disease. The relationship between cancer and depression has been evolving dynamically in recent times. The current research findings indicate a strong association between cancer and depression. However, the direction of causality remains unclear. Focusing on depression in cancer patients may, therefore, be beneficial for these patients.

RESUMEN

BACKGROUND: Common bile duct (CBD) stones commonly occur in cholecystectomy cases. The management options include laparoscopic CBD exploration (LCBDE) or endoscopic retrograde cholangiopancreatography (ERCP) followed by laparoscopic cholecystectomy (LC). Although ERCP is fully developed, it has complications, and LCBDE is a proven alternative. This study aimed to evaluate the safety and efficacy of these treatments in elderly individuals aged ≥70 years. METHODS: A retrospective study between January 2015 and July 2022 included 160 elderly patients (aged ≥70 years) diagnosed with cholelithiasis and choledocholithiasis. The patients were divided into 1-stage (LCBDE [n = 80]) or 2-stage (ERCP followed by LC [n = 80]) treatment groups. Data collected encompassed comorbidities, symptoms, bile duct clearance, postoperative complications, and long-term outcomes for systematic analysis. RESULTS: This study analyzed 160 patients treated for CBD stones, comparing 1-stage and 2-stage groups. The 1-stage group had more female patients than the 2-stage group (57.5% vs 37.5%, respectively). The 1-stage group had a mean age of 80.55 ± 7.00 years, which was higher than the mean age in the 2-stage group. American Society of Anesthesiologists classification, Charlson Comorbidity Index, and laboratory findings were similar. Pancreatitis and cholangitis occurred after ERCP in the 2-stage group. Stone clearance rates (92.35% [1-stage group] vs 95.00% [2-stage group]) and biliary leakage incidence (7.5% [1-stage group] vs 3.0% [2-stage group]) were similar, as were postoperative complications and long-term recurrence rates (13.0% [1-stage group] vs 12.5% [2-stage group]). CONCLUSION: Our research indicates that both the combination of LCBDE and LC and the sequence of ERCP followed by LC are equally efficient and secure when treating CBD stones in elderly patients. Consequently, the 1-stage procedure may be considered the preferred treatment approach for this demographic.

RESUMEN

The accumulation of ß-sheet-rich α-synuclein (α-Syn) protein in human brain cells is a pathological hallmark of Parkinson's disease (PD). Moreover, it has been reported that familial PD mutations (A30P, E46K, H50Q, G51D, and A53T) accumulate at an accelerated rate both in vivo and in vitro. In addition, accumulations of various C-terminal α-Syn truncations, such as C-terminal-truncated N103 α-synuclein (N103), were found in an aggregated form in the brain tissue of PD patients. Fluorescent protein-tagged wild-type α-Syn, A30P, E46K, H50Q, G51D, A53T, and N103 were transfected into HEK293T and SHSY5Y cells, and their diffusion behaviors were investigated with a custom-built fluorescence microscope system. Based on our experimental results, the oligomerization of α-Syn is a time-dependent process in both HEK293T and SHSY5Y cells, and the oligomer state approaches a plateau after 48 h of transfection. The change in the oligomeric state of E46K, H50Q, and G51D exhibited a similar trend to the wild type at a lower concentration but became intense at a higher concentration. A53T and N103 possess smaller diffusion coefficients than wild-type α-synuclein and other family PD mutations, indicating that these two mutants could form higher oligomeric states or stronger interactions in HEK293T and SHSY5Y cells. In contrast, the smallest oligomer and the lowest intracellular interaction among all investigated α-Syn variants were found for A30P. These phenomena indicated the presence of different pathogeneses among familial PD mutants and C-terminal α-Syn truncations.

RESUMEN

This study aimed to describe our experience and discuss the results, controversies, and the use of percutaneous transhepatic biliary drainage (PTBD) in patients with biliary complications after liver transplantation (LT). Between November 2009 and August 2020, 76 consecutive patients who underwent 77 LTs (44 deceased donor LTs and 33 living donor LTs [LDLT]) were enrolled retrospectively. Endoscopic therapy as initial approach and PTBD as rescue therapy were used for patients with biliary complications. There were 31 patients (31/76, 40.8%) with biliary complications, and two of them died (2/31, 6.5%). Clinical success rate of endoscopic therapy alone was 71.0% (22/31). The remaining nine patients received salvage PTBD and their clinical results were observed according to whether their intrahepatic bile ducts (IHBDs) was dilated (group A, n = 5) or not (group B, n = 4). In group A, the technical and long-term clinical success rates of PTBD were 100% and 20%, respectively. These five patients received PTBD ranging from 75 to 732 days after their LTs, and no procedure-related complications were encountered. In group B, the technical and long-term clinical success rates of PTBD were 50% and 25%, respectively. Three group B patients (75%) underwent PTBD within 30 days after LDLT and had lethal complications. One patient had graft laceration and survived after receiving timely re-transplantation. The other two patients died of sepsis due to PTBD-related bilioportal fistula or multiple liver abscesses. Our experience showed salvage PTBD played a limited role in biliary complications without dilated IHBDs within 1 month after LT.

RESUMEN

There are discrepancy between MR findings and clinical presentations. The compressed cervical cord in patients of the spondylotic myelopathy may be normal on conventional MRI when it is at the earlier stage or even if patients had severe symptoms. Therefore, it is necessary to take a developed MR technique--diffusion tensor imaging (DTI)--to detect the intramedullary lesions. Prospective MR and DTI were performed in 53 patients with cervical compressive myelopathy and twenty healthy volunteers. DTI was performed along six non-collinear directions with single-shot spin echo echo-planar imaging (EPI) sequence. Intramedullary apparent diffusion coefficient (ADC) and fractional anisotropy (FA) values were measured in four segments (C2/3, C3/4, C4/5, C5/6) for volunteers, in lesions (or the compressed cord) and normal cord for patients. DTI original images were processed to produce color DTI maps. In the volunteers' group, cervical cord exhibited blue on the color DTI map. FA values between four segments had a significant difference (P < 0.01), with the highest FA value (0.85 ± 0.03) at C2/3 level. However, ADC value between them had no significant difference (P > 0.05). For patients, only 24 cases showed hyperintense on T2-weighted image, while 39 cases shown patchy green signal on color DTI maps. ADC and FA values between lesions or the compressed cord and normal spinal cord of patients had a significant difference (both P < 0.01). FA value at C2/3 cord is the highest of other segments and it gradually decreases towards the caudal direction. Using single-shot spin echo EPI sequence and six non-collinear diffusion directions with b value of 400 s mm(-2), DTI can clearly show the intramedullary microstructure and more lesions than conventional MRI.

RESUMEN

OBJECTIVE: To identify the etiology of an aseptic encephalitis outbreak (ten cases) in a hospital of Xiamen city from 11 to 17 May, 2011. METHODS: A total of ten patients' throat swabs, anal swabs and cerebrospinal fluid were collected and detected by RT-PCR for pan-enterovirus. The samples containing detectable pan-enterovirus were tested by PCR with genotype-specific general primers located in VP1 region of enterovirus genotype A, B and C (HEV-A, B and C). The PCR products of VP1 segment were purified and sequenced, and phylogenetic analysis was performed. Meanwhile, the pathogens in those samples were isolated in Vero cell culture. Homologous analysis of VP1 sequences were carried out for the cultured virus samples and the original clinical samples to identify the outbreak etiology. RESULTS: Among the ten cases, seven cases were positive for pan-enterovirus nucleic acid. When tested by genotype-specific PCR, the throat and anal swab samples from those 7 patients were positive with HEV-B VP1 primers. Meanwhile, the HEV-B VP1 segments were sequenced and phylogenetic analyzed, which indicated the seven cases were all infected by enterovirus Echo 30. The sequences from those samples had homology of 95.3% - 97.1% with the epidemic strains in Zhejiang, 2004. Out of the seven cases, the sequences of XM2, XM3, XM4, XM8 throat swab samples and XM3, XM6 throat samples showed 99.4% - 100.0% homology which were different from the sequence of XM1, and the homology was 92.8% - 93.4%. Furthermore, the viruses were isolated using Vero cells from XM1, XM2, XM3, XM4 and XM8 throat swab samples, and the VP1 sequence showed more than 99.9% homology with the original specimens. CONCLUSION: The local outbreak of aseptic encephalitis was caused by Echo 30 of enterovirus genotype B, and the epidemic strains may have different genetic background.

RESUMEN

OBJECTIVE: To observe the curative effects of transmetil on Amanita verna poisoning. METHODS: Twelve cases with Amanita verna poisoning were reviewed. The patients were divided into 2 groups according to usage of transmetil: Group A was treated with traditional protocol (gastric lavage, catharsis, rehydration, diuresis, anti-infection and hemodialysis), Group B was treated with traditional protocol combined with transmetil. The liver function changes on the 1st, 3rd, 5th and 7th day after poisoning and the mortality were compared between 2 groups. RESULTS: Two cases in group A (6 patients) died. The mortality of group A was 33.3%. The AST levels continued to increase on the 3rd and 5th day, but decreased on the 7th day. TBIL continued to increased on the 1st, 3rd, 5th and 7th day. None in group B died. The TBIL level dropped at 7 d 5 patients showed an increase in ALT at 7 d and 3 patients showed a decrease in AST at 7 d. CONCLUSION: Transmetil may play an important role in reducing the mortality of Amanita verna poisoning.

RESUMEN

OBJECTIVE: To study the changes of plasma vasoactive intestinal peptide (VIP) levels and the relationship of plasma VIP levels with feeding intolerance (FI) in preterm infants. METHODS: Plasma VIP concentrations were measured using radioimmunoassay in 53 preterm infants with FI 1, 4, 7 and 14 days after birth. Fifty-nine preterm infants without FI served as the control group. RESULTS: The fasting plasma concentrations of VIP in the FI group 1, 4 and 7 days after birth (129 ± 46, 144 ± 32 and 166 ± 31 pg/mL respectively) were significantly lower than those in the control group (195 ± 63, 197 ± 31 and 205 ± 34 pg/mL respectively) (P<0.05). The increased plasma VIP concentrations were associated with the increased gestational age, age in days and enteral feeding volume in the FI group. By 14 days, the plasma concentrations of VIP in the FI group (198 ± 41 pg/mL) were similar to those in the control group (202 ± 48 pg/mL) (P>0.05). The younger the infant's gestational age, the more prolonged the FI. Plasma levels of VIP on day 1 of life in the FI group were negatively correlated with the duration of FI (r=-0.799, P<0.05). CONCLUSIONS: Plasma levels of VIP might be related to the development of FI in preterm infants and might serve as a predictor of FI.

RESUMEN

Alzheimer's disease (AD) is characterized by the presence of extracellular senile plaques formed by ß-amyloid (Aß) peptides in the patient's brain. Previous studies have shown that the plaques in the AD brains are colocalized with the advanced glycation end products, which is mainly formed from a series of nonenzymatic reactions of proteins with reducing sugars or reactive dicarbonyls. Glycation was also demonstrated to increase the neurotoxicity of the Aß peptides. To clarify the impact of glycation on Aß aggregation, we synthesized two glycated Aß42 peptides by replacing Lys16 and Lys28 with Nε-carboxymethyllysine respectively to mimic the occurrence of protein glycation. Afterward, we monitored the aggregation kinetics and conformational change for two glycated peptides. We also used fluorescence correlation spectroscopy to probe the early stage of peptide oligomerization and tested their abilities in copper binding and reactive oxygen species production. Our data show that glycation significantly slows down the aggregation process and induces more cytotoxicity especially at position 28. We speculated that the higher toxicity might result from a relatively stable oligomeric form of peptide and not from ROS production. The data shown here emphasized that glycated proteins would be an important therapeutic target in AD treatments.

RESUMEN

Liver transplantation (LT) candidates often present with poor oral hygiene, which could potentially lead to systemic infections and sepsis owing to their cirrhotic state. In this study, we investigated the oral health status of LT candidates and propose guidance for the detection and treatment of encountered oral lesions among these patients. The decayed, missing, and filled teeth (DMFT) index was determined through oral examination. The presence of dental calculus was detected using panoramic radiography and defined by the radiopaque dental calculus (RDC). From January 2011 to August 2018, 56 LT candidates were enrolled with a median follow-up of 39 months. The overall mean numbers of decayed, missing, and filled teeth among these patients were 2.7 ± 2.8, 10.9 ± 8.3, and 5.4 ± 4.5, respectively. Eighteen patients (32.1%) had RDC. The 5-year survival rates of all 56 patients was 57.7%, while that of those who either received LT (23 patients) or not were 82.1% and 39.8%, respectively. A Cox regression model revealed better overall survival of patients after LT (adjusted hazard ratio [aHR] = 0.067, p = 0.001), worse survival among patients with RDC (aHR = 3.468, p = 0.010), at Child-Pugh stages B and C (aHR for stage B = 11.889, p = 0.028; aHR for stage C = 19.257, p = 0.013) compared to patients at Child-Pugh stage A, and those with a model for end-stage liver disease (MELD) score ≥25 (aHR = 13.721, p = 0.018). This study demonstrates that RDC was associated with worse prognosis in LT candidates. We therefore recommend that interprofessional collaboration should be a routine preoperative procedure for the evaluation of oral hygiene among LT candidates.

RESUMEN

BACKGROUND: This study aims to investigate the association between vitamin D (VD) and lung cancer skin metastasis (LCSM). METHODS: The following databases will be retrieved from the beginning to the present of each database without language limitation: PUBMED, EMBASE, Cochrane Library, Web of Science, CBM, and CNKI. The reference lists of included trials and other sources will also be checked. Two researchers will independently undertake literature selection, data collection, and study quality evaluation. We will utilize a fixed or random-effect model to pool the data according to the heterogeneity test. The RevMan 5.3 software will be used to analyze the data and perform meta-analysis. RESULTS: This study will summarize high quality study to explore the association between VD and LCSM. CONCLUSION: The findings of this study will help to judge whether there is association between VD and LCSM. ETHICS AND DISSEMINATION: No research ethical approval is required in this study, because it will only analyze published data. It is expected to disseminate through a peer-reviewed journal. STUDY REGISTRATION: osf.io/ph2au.

RESUMEN

BACKGROUND: Effective prognostic biomarkers and powerful target-therapeutic drugs are needed for improving the treatment of Hepatocellular carcinoma (HCC). OBJECTIVE: This study aimed to evaluate the expression of FOXM1 and Aurora-A and their prognostic value in HCC. METHODS: We determined the differentially expressed genes signature in HCC using the Gene Set Enrichment Analysis (GSEA), and then evaluated the expression of FOXM1 and Aurora-A in TCGA and KMUH cohort. Associations between co-expression of FOXM1 and Aurora-A and clinical variables were calculated. Overall survival (OS) and recurrence-free survival (RFS) were estimated with different FOXM1 and Aurora-A expression status. RESULTS: FOXM1-related gene sets were mostly associated with cell cycle regulation in HCC tissues. We found a positive correlation between the expression of FOXM1 and Aurora-A. Overexpression of FOXM1 and Aurora-A was associated with larger tumor size, advanced stage, higher grade, and double-positive for HBV and HCV. The coordinated overexpression of FOXM1 and Aurora-A was the most significant independent prognostic factor for OS and RFS. Furthermore, the concomitant high expression of FOXM1 and Aurora-A predicted the worst OS of sorafenib-treated patients with HCC. CONCLUSIONS: The co-expression of FOXM1 and Aurora-A could be a reliable biomarker to predict the sorafenib response and prognosis of HCC patients.
