Arterial chemotherapy for hepatocellular carcinoma in China: consensus recommendations. Hepatol Int 2024; 18:4-31. [PMID: 37864725 DOI: 10.1007/s12072-023-10599-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/07/2023] [Accepted: 09/17/2023] [Indexed: 10/23/2023] [Imported: 11/06/2023]
Abstract
Hepatocellular carcinoma (HCC) is one of the most common malignancies and the third leading cause of cancer-related deaths globally. Hepatic arterial infusion chemotherapy (HAIC) treatment is widely accepted as one of the alternative therapeutic modalities for HCC owing to its local control effect and low systemic toxicity. Nevertheless, although accumulating high-quality evidence has displayed the superior survival advantages of HAIC of oxaliplatin, fluorouracil, and leucovorin (HAIC-FOLFOX) compared with standard first-line treatment in different scenarios, the lack of standardization for HAIC procedure and remained controversy limited the proper and safe performance of HAIC treatment in HCC. Therefore, an expert consensus conference was held on March 2023 in Guangzhou, China to review current practices regarding HAIC treatment in patients with HCC and develop widely accepted statements and recommendations. In this article, the latest evidence of HAIC was systematically summarized and the final 22 expert recommendations were proposed, which incorporate the assessment of candidates for HAIC treatment, procedural technique details, therapeutic outcomes, the HAIC-related complications and corresponding treatments, and therapeutic scheme management.

Hepatic arterial infusion chemotherapy combined with anti-PD-1/PD-L1 immunotherapy and molecularly targeted agents for advanced hepatocellular carcinoma: a real world study. Front Immunol 2023; 14:1127349. [PMID: 37180098 PMCID: PMC10169627 DOI: 10.3389/fimmu.2023.1127349] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2022] [Accepted: 03/31/2023] [Indexed: 05/15/2023] [Imported: 11/06/2023] Open
Abstract
Background Molecular targeted therapy combined with immunotherapy significantly improves the prognosis of patients with advanced liver cancer. Additionally, hepatic arterial infusion chemotherapy (HAIC) can improve the prognosis of patients with advanced liver cancer. This real-world study aimed to evaluate the clinical efficacy and safety of HAIC combined with molecular targeted therapy and immunotherapy in the treatment of primary unresectable hepatocellular carcinoma (uHCC). Methods A total of 135 patients with uHCC were enrolled in this study. Progression-free survival (PFS) was the primary endpoint. The efficacy of the combination therapy was assessed based on the modified Response Evaluation Criteria in Solid Tumors (mRECIST) guidelines. Overall survival (OS), adverse events (AEs) and surgical conversion rate were the secondary endpoints. Univariate and multivariate Cox regression analyses were performed to examine independent prognostic factors. For sensitivity analysis, inverse probability weighting (IPW) was used to balance the influence of the tested confounding factors between groups to verify the robustness of conversion surgery for survival benefits. The E-values were estimated to assess robustness to unmeasured confounders. Results The median number of therapies was three. Approximately 60% of the patients had portal vein tumour thrombosis (PVTT). The most common targeted drugs were lenvatinib and bevacizumab, whereas the most common immunotherapy drug was sintilimab. The overall objective response rate (ORR) was 54.1%, and the disease control rate (DCR) was 94.6%. A total of 97 (72%) patients experienced AEs of grades 3-4. Fatigue, pain and fever were the most common symptoms of grade 3-4 AEs. The median PFS was 28 months and 7 months in the successful and unsuccessful conversion groups, respectively. The median OS was 30 months and 15 months in the successful and unsuccessful conversion groups, respectively. Successful conversion surgery, sex, hapatic vein invasion, BCLC stage, baseline tumour size, AFP levels and maximum therapeutic response were independent prognostic factors for PFS. Successful conversion surgery, number of interventions, hapatic vein invasion and total bilirubin levels were independent prognostic factors for OS. After IPTW, no standardised differences exceeding 0.1 were found. IPW-adjusted Kaplan-Meier curves showed that successful conversion surgery was an independent prognostic factor for both PFS and OS. The E-values of successful conversion surgery were 7.57 and 6.53 for OS and PFS, respectively, which indicated a relatively robust impact of successful conversion surgery on the prognosis of patients. Conclusion Patients with primary uHCC undergoing HAIC combined with immunotherapy and molecular targeted therapy have a higher tumour regression rate and the side effects are manageable. Patients undergoing surgery after combination therapy have survival benefits.

[PMID: 36686799 PMCID: PMC9846108 DOI: 10.3389/fonc.2022.1071860] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2022] [Accepted: 12/09/2022] [Indexed: 01/05/2023] [Imported: 11/05/2023] Open
Abstract
Background In recent years, hepatic arterial infusion chemotherapy (HAIC) has gained popularity in the treatment of hepatocellular carcinoma. Although several studies have been published, no bibliometric analysis have been conducted on this topic. Objectives To understand the development status and future trends in the application of HAIC, we conducted bibliometric analysis to examine the cooperation and influence among countries, institutions, authors, and journals. Methods All relevant articles and reviews on the use of HAIC in HCC treatment were retrieved from the Web of Science database. A bibliometric analysis of countries, institutions, journals, authors, and keywords related to this field was performed using R and VOSviewer software. The main aspects analyzed were the research status and key fields of HAIC in HCC treatment. Results A total of 1026 articles published in 292 journals by 4937 authors from 959 institutions between 1974 and 2021 were retrieved. A rapid increase in articles published after 1990 was observed, which reached the peak in 2021. Japan had the most publications and citations. Yonsei University, Sun Yat-sen University, and Hiroshima University were the three leading institutions in research on this topic. Kwang-Hyub Han and Masatoshi Kudo have the greatest academic influence in this field. Most publications were made in the Hepato-Gastroenterology, whereas cancer had the most citations. The main aspects of HAIC treatment of HCC include HAIC and TACE, chemotherapy drug selection, HAIC and targeted therapy and immunotherapy, HAIC and surgery, and hepatotoxicity. Keywords such as FOLFOX, lenvatinib, hepatic arterial infusion chemotherapy are hot words in this field in recent years. Conclusion The research on the use of HAIC in the treatment of HCC has been on the rise. Currently, HAIC combined with targeted therapy or immunotherapy has attracted significant attention.

[PMID: 36199359 PMCID: PMC9527326 DOI: 10.3389/fbioe.2022.996177] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2022] [Accepted: 08/29/2022] [Indexed: 11/29/2022] [Imported: 11/05/2023] Open
Abstract
MXene nanosheets have shown exciting potential in nanomedicine because of their large surface area, intense near-infrared (NIR) absorbance, and good biocompatibility. However, their development in the direction of treating tumors is constrained by the limitations of existing design methodologies. These methodologies lack control over the size and distribution of tumors. Moreover, their photodynamic therapy (PDT) effect is poor. To address this unmet medical need, a simple strategy that processes MXene with carbon nanotube (CNT) into a three-dimensional (3D) honeycomb structure having anti aggregation capacity was established. The structure can be used in disease phototherapy against tumors, bacteria, and viruses, such as photothermal therapy (PTT), photodynamic therapy (PDT), and multimodal synergistic therapy. In the present study, 3D CNT/MXene microspheres were obtained by the template method and spray-drying method. The microspheres possessed special photothermal effects and photothermal stability under NIR laser irradiation. Furthermore, the developed microspheres could achieve a maximum of 85.6% drug loading capability of doxorubicin (DOX). Under light irradiation at 650 and 808 nm, 3D CNT/MXene microspheres could efficiently produce singlet oxygen due to the effectiveness of CNTs as carries for Titanium Dioxide (TiO2) photosensitizers present on the MXene surface. Furthermore, in vitro studies had showed that 3D CNT/MXene-DOX effectively inhibited the proliferation of HeLa cells. Hence, this study provides a promising platform for future clinical applications to realize PTT/PDT/chemotherapy combination cancer treatment based on MXene.

Abstract
Background Biliary tract cancer (BTC) is an uncommon but highly lethal malignancy with poor clinical outcomes. To promote the development of precision medicine for BTC, uncovering its genomic profile becomes particularly important. However, studies on the genomic feature of Chinese BTC patients remain insufficient. Methods A total of 382 Chinese patients with BTC were enrolled in this study, including 71 with intrahepatic cholangiocarcinoma (ICC), 194 with extrahepatic cholangiocarcinoma (ECC), and 117 with gallbladder carcinoma (GBC). Genetic testing was performed by utilizing the next-generation sequencing (NGS) of 499 cancer-related genes and the results were compared to those of Western BTC patients (MSKCC cohorts). Results The most prevalent genes were TP53 (51.6%), ARID1A (25.9%), KMT2C (24.6%), NCOR1 (17%), SMAD4 (15.2%), KRAS (14.9%), KMT2D (14.9%), ATM (14.1%), and APC (13.9%) in Chinese BTC patients. TP53, SMAD4, and APC were more prevalent in GBC, ECC, and ICC, respectively. In addition, 10.5% of Chinese BTC patients harbored pathogenic or likely pathogenic (P/LP) germline alterations in 41 genes, which were mainly related to DNA damage repair (DDR). Additionally, the genomic features of Chinese and Western BTC tumors were similar, with the exception of the notable difference in the prevalence of TP53, KRAS, IDH1, KMT2C, and SMAD4. Notably, Chinese BTC patients had high prevalence (57.1%) of actionable alterations, especially for those with ECC, and half (192/382) of them had somatic DDR alterations, with the prevalence of deleterious ones being significantly higher than their Western counterparts. Twenty-three percent of patients had a higher tumor mutational burden (TMB-H, over 10 mutations/MB), and TMB was significantly higher in those with deleterious DDR alterations and/or microsatellite instability-high. The most common mutational signature in BTC patients was Signature 1, and interestingly, Signatures 1, 4, and 26 were significantly associated with higher TMB level, but not with the survival of patients who had received immunotherapy in pan-cancer. Conclusion Our study elaborated the distinct germline and somatic genomic characteristics of Chinese BTC patients and identified clinically actionable alterations, highlighting the possibility for the development and application of precision medicine.

Abstract
Hepatocellular carcinoma (HCC) remains a major public health problem. MCM4, a constitutive member of the minichromosomal maintenance protein family, has been reported to play a vital role in cancer malignancy behavior. However, the function of MCM4 in HCC remains largely unknown. The present study explored the specific role of MCM4 in HCC. The data from public datasets including TCGA and GTEx showed that MCM4 was overexpressed in HCC and significantly associated with poor prognosis. Immunohistochemistry results from 102 HCC patients suggested that high-level expression of MCM4 was correlated with tumor size. Then a series of in vivo and in vitro experiments were performed to investigate the function of MCM4 in HCC tumor cells. MCM4 silencing suppressed the cell proliferation and sphere formation of hepatoma cells. Moreover, silencing MCM4 significantly decreased the growth of tumors in a xenograft tumor model. In conclusion, the results of the present study indicated that MCM4 was a potential prognostic predictor associated with poor outcomes of HCC patients and even a therapeutic target for HCC.

[PMID: 33593355 PMCID: PMC7885361 DOI: 10.1186/s12935-021-01800-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2020] [Accepted: 02/03/2021] [Indexed: 12/27/2022] [Imported: 11/05/2023] Open
Abstract
Background Overexpression of ABC transporters is a big challenge on cancer therapy which will lead cancer cells resistance to a series of anticancer drugs. Gedatolisib is a dual PI3K and mTOR inhibitor which is under clinical evaluation for multiple types of malignancies, including colorectal cancer. The growth inhibitory effects of gedatolisib on colorectal cancer cells have been specifically studied. However, the role of ABC transporters on gedatolisib resistance remained unclear. In present study, we illustrated the role of ABC transporters on gedatolisib resistance in colorectal cancer cells. Methods Cell viability investigations of gedatolisib on colorectal cancer cells were determined by MTT assays. The verapamil and Ko143 reversal studies were determined by MTT assays as well. ABCB1 and/or ABCG2 siRNA interference assays were conducted to verify the role of ABCB1- and ABCG2-overexpression on gedatolisib resistance. The accumulation assays of gedatolisib were conducted using tritium-labeled paclitaxel and mitoxantrone. The effects of gedatolisib on ATPase activity of ABCB1 or ABCG2 were conducted using PREDEASY ATPase Kits. The expression level of ABCB1 and ABCG2 after gedatolisib treatment were conducted by Western blotting and immunofluorescence assays. The well-docked position of gedatolisib with crystal structure of ABCB1 and ABCG2 were simulated by Autodock vina software. One-way ANOVA was used for the statistics analysis. Results Gedatolisib competitively increased the accumulation of tritium-labeled substrate-drugs in both ABCB1- and ABCG2-overexpression colorectal cancer cells. Moreover, gedatolisib significantly increased the protein expression level of ABCB1 and ABCG2 in colorectal cancer cells. In addition, gedatolisib remarkably simulated the ATPase activity of both ABCB1 and ABCG2, suggesting that gedatolisib is a substrate drug of both ABCB1 and ABCG2 transporters. Furthermore, a gedatolisib-resistance colorectal cancer cell line, SW620/GEDA, was selected by increasingly treatment with gedatolisib to SW620 cells. The SW620/GEDA cell line was proved to resistant to gedatolisib and a series of chemotherapeutic drugs, except cisplatin. The ABCB1 and ABCG2 were observed overexpression in SW620/GEDA cell line. Conclusions These findings suggest that overexpression of ABCB1 and ABCG2 may restrict the efficacy of gedatolisib in colorectal cancer cells, while co-administration with ABC transporter inhibitors may improve the potency of gedatolisib.

Abstract
Objective This study is aimed to provide a clinical basis for the identification and treatment of patients with malignant biliary obstruction (MBO) complicated with biliary infection by comparing pathogenic bacteria detected in bile and blood cultures from these patients. Materials and Methods A total of 380 patients with MBO who received percutaneous transhepatic cholangic drainage from January 2004 to January 2019 were included in the study. A total of 90 patients were diagnosed with having MBO complicated with biliary infection, and bile and blood culture were simultaneously performed on these patients. The patients included 58 men and 32 women, ranging in age from 33 to 86 years old, with a mean age of 60.69 years. Results The detection rate using bile bacterial culture in patients with MBO complicated with biliary infection was significantly higher than that using blood culture, and there were significant differences in the two kinds of bacterial culture found positive bile and blood cultures from the same patients. Gram-positive cocci were dominant in the bile cultures and Gram-negative bacilli were dominant in the blood cultures. Therefore, it is necessary to conduct simultaneous bile bacterial culture and blood culture for patients with MBO complicated with biliary infection, especially those with severe or critical diseases. Conclusions It is vital to enable simultaneous bile bacterial culture and blood culture in patients with MBO complicated with biliary infection. Existing guidelines for the diagnosis and treatment of benign biliary infection are not applicable to patients with MBO complicated with biliary infection.

Abstract
Pancreatic cancer (PC) is a lethal disease with extremely high mortality. Although surgical resection is the optimal therapeutic approach for PC, about 30%-40% of those patients are not candidates for surgical resection when diagnosed. Chemotherapy and radiotherapy also could not claim a desirable effect on PC. The application of interventional radiology approaches is limited by unavoidable damage to the surrounding vessels or organs. By the superiority of mechanism and technology, IRE could ablate the tumor by creating irreversible pores on the membrane of PC cells with other tissues like vessels and pancreatic ducts untouched. This consensus gathers the theoretical basis and clinical experience from multiple Chinese medical centers, to provide the application principles and experience from Chinese experts in the IRE field.

Abstract
Objective We sought to analyze the efficacy and safety of preserving the Oddis sphincter during metallic biliary stent implantation in patients with malignant obstructive jaundice. Materials and Methods In a retrospective analysis, 133 patients with malignant obstructive jaundice who were admitted to our hospital from January 2010 to January 2017 and who underwent metallic biliary stent implantation were divided into two groups - the Oddis sphincter retention group (n = 55) and the Oddis sphincter nonretention group (n = 78) - according to whether the Oddis sphincter was left untouched during stent placement. The patient clinical data as well as information on complications, time of stent patency, improvement in liver function, and decline of serum bilirubin were reviewed and evaluated. Statistical analysis was performed using the Statistical Package for the Social Sciences version 19.0 (IBM Corp., Armonk, NY, USA, USA) and Prism version 7 (GraphPad Software, San Diego, CA, USA). Results The median follow-up time was 9.6 months (range: 1-20 months) and there was no significant difference in general clinical information between the two groups. However, the incidence rates of acute biliary infection, recurrent biliary infection, acute pancreatitis, chronic pancreatitis, and asymptomatic pancreatic enzyme levels were higher in the Oddis sphincter retention group and the differences were all statistically significant (P < 0.05). Conversely, there were no significant differences in bilirubin decline, liver function improvement, and stent patency between the two groups (P > 0.05). Conclusion Leaving the Oddis sphincter untouched during biliary stent placement can reduce the incidence of postoperative complications, while there was no effect on stent patency or jaundice relief. Therefore, it is recommended to preserve the Oddis sphincter when the stenosis is more than 3 cm above the duodenal papilla.

Abstract
Objective To research the effect of matrine on the proliferation and migration of HepG2 cells through extracellular signal-regulated kinase 1/2 (ERK1/2) signaling pathway. Methods HepG2 cell was selected and divided into blank control group, experimental group (matrine 1, 2, and 4 mg/mL), and positive control group (PD98059, ERK1/2 inhibitor). MTT measure was used to detect the effective time and concentration which matrine inhibits HepG2 cells. After 24 h, the effect of effective concentration of matrine on the of morphological changing HepG2 cells was observed. The invasion ability was assayed by transwell method, the expression of ERK1/2 and pERK1/2 were detected through Western blot, and reverse transcription polymerase chain reaction was used to test the expression level of ERK1/2 mRNA. Results With the increase of matrine concentration, the number of adherent HepG2 cells gradually decreased, the morphologic changes gradually became spherical, some cell morphology was incomplete, and even cell fragments appeared. The proliferation and invasion ability of HepG2 cells decreased. The expression of ERK1/2, pERK1/2, and ERK1/2 mRNA downregulated with the increase of matrine concentration (P < 0.05). Conclusion Matrine inhibits the proliferation and migration of HepG2 cells by downregulating the ERK1/2 signaling pathway.

Abstract
Background Evaluating the molecular characteristics of brain metastases is limited by difficult access and by the blood–brain barrier, which prevents circulating tumor DNA (ctDNA) from entering the blood. In this study, we aimed to compare the sequencing results from cerebrospinal fluid (CSF) ctDNA versus plasma ctDNA, plasma circulating tumor cells (CTCs), and brain tissue specimens from patients with brain metastasis from non‐small cell lung cancer (NSCLC). Methods This was a prospective study of 21 consecutive patients with NSCLC and brain metastasis diagnosed between April 2018 and January 2019. Samples of CSF and peripheral blood were obtained from all 21 patients. Brain tissues were obtained from five patients after surgical resection. Next‐generation sequencing was performed using the Ion system. Single nucleotide variants (SNVs) and small insertions or deletions (indels) were searched. Results Mutations were detected in the CSF ctDNA of 20 (95.2%) patients. The detection rate of epidermal growth factor receptor (EGFR) mutations in CSF ctDNA was 57.1% (12/21) whereas this rate was only 23.8% (5/21) in peripheral blood ctDNA and in CTCs. EGFR mutations were found in the CSF of 9 of 11 (81.8%) patients with leptomeningeal metastases, as compared with three of 10 (30%) patients with brain parenchymal metastases. Mutations were also detected in KIT, PIK3CA, TP53, SMAD4, ATM, SMARCB1, PTEN, FLT3, GNAS, STK11, MET, CTNNB1, APC, FBXW7, ERBB4, and KDR (all >10%). The status of EGFR and TP53 mutations was consistent between CSF ctDNA and brain lesion tissue in all five patients. Conclusion Sequencing of CSF ctDNA revealed specific mutation patterns in driver genes among patients with NSCLC and brain metastasis. Key points In some small‐sample studies, the importance of cerebrospinal fluid in guiding the treatment of cancerous brain lesions has been verified in that it may reflect genomic mutations of brain tumors relatively accurately. Cerebrospinal fluid is a new form of liquid biopsy that can be helpful in improving the management of patients with brain metastasis from non‐small cell lung cancer by detecting genetic abnormalities specific to brain metastases.

Abstract
Background The symptoms of patients with malignant biliary obstruction (MBO) could be effectively alleviated with percutaneous transhepatic biliary drainage (PTBD). Postoperative infections were considered as challenging issues for clinicians. In this study, the risk factors of biliary infection in patients after PTBD were analyzed. Methods From July 2003 to September 2010, 694 patients with MBO received PTBD treatment. Bile specimens were also collected during PTBD. All relevant information and results were collected, including gender, age, obstruction time, types of primary tumor, sites of obstruction, drainage style, tumor stage, hemoglobin, phenotype of peripheral blood monocyte (Treg), total bilirubin, direct bilirubin, albumin, Child-Pugh score, and results of bile bacterial culture. Results For the 694 patients involved in this study, 485 were male and 209 were female, with a mean age of 62 years (ranged 38-78 years). For the bile culture, 57.1% patients (396/649) were negative and 42.9% patients showed positive (298/694), and then 342 strains of microorganism were identified. The risk factors of biliary system infection after PTBD included: age (χ2 = 4.621, P = 0.032), site of obstruction (χ2 = 17.450, P < 0.001), drainage style (χ2 = 14.452, P < 0.001), tumor stage (χ2 = 4.741, P = 0.029), hemoglobin (χ2 = 3.914, P = 0.048), Child-Pugh score (χ2 = 5.491, P = 0.019), phenotype of peripheral blood monocyte (Treg) (χ2 = 5.015, P = 0.025), and results of bile bacterial culture (χ2 = 65.381, P < 0.001). Multivariate analysis suggested that high-risk factors were drainage style, Child-Pugh score, and results of bile culture. Conclusions The risk factors of biliary infection after PTBD included: age, site of obstruction, drainage style, tumor stage, hemoglobin, Child-Pugh score, phenotype of peripheral blood monocyte (Treg), and results of bile culture. It was further concluded that drainage style, Child-Pugh score, and results of bile culture were independent risk factors.

Abstract
Objective: To evaluate the efficacy and safety of dexmedetomidine as a basic analgesic sedative for patients with radiofrequency ablation of liver tumors. Methods: A total of 443 liver cancer patients underwent percutaneous radiofrequency ablation in the 302 Hospital of PLA from January 2015 to December 2016 were retrospectively studied. The experimental group was dexmedetomidine group, with a total of 165 cases. The control group was pethidine group with a total of 278 cases. The indexes of systolic blood pressure, diastolic blood pressure, heart rate and respiratory rate of two groups were collected before and after operation, and the VAS score and incidence of nausea and adverse reactions were recorded. Results: The results of the experimental group added dose of pethidine (64.6 mg) lower than that of the control group pethidine dose (90.8 mg), the difference was statistically significant (Z=-10.205 3, P<0.01). The experimental group and the control group with VAS score average value was not statistically significant(Z=1.801 9, P=0.076), group two with 4 points for the critical point of the stratification, more than 4 points and<4 group comparison, the test group VAS score greater than 4 were significantly lower than the control group (χ(2)=7.05, P=0.007 9). The systolic blood pressure and diastolic blood pressure in the experimental group were significantly lower than those before operation (P<0.01), while the systolic blood pressure and diastolic blood pressure in the control group significantly increased compared with those before operation. Dexmedetomidine has the effect of stabilizing hemodynamics. The heart rate of the two groups decreased, and the rate of heart rate decreased in the experimental group. In addition, dexmedetomidine did not significantly increase the incidence of nausea and vomiting compared with the control group. Conclusions: Dexmedetomidine is safe and effective as a basic drug for analgesic and sedative in patients with liver tumor radiofrequency ablation.

Abstract
Biopsy has been used to diagnose thoracic diseases for more than a century. Percutaneous needle biopsy plays a crucial role in the diagnosis, staging, and treatment planning for tumors in the lungs, thoracic wall, hilum, and mediastinum. With the continuous improvement in imaging techniques, the range of clinical applications for percutaneous needle biopsy is also expanding. It has become important to improve Chinese professionals’ and technicians’ understanding of percutaneous transthoracic needle biopsy (PTNB) in order to standardize operating procedures and to strengthen perioperative management. However, there is currently no Chinese expert consensus that provides systematic standardization and guidance for PTNB in clinical practice. The Committee of Chinese Society of Interventional Oncology (CSIO) of the Chinese Anti‐Cancer Association (CACA) initiated a Chinese multidisciplinary expert consensus on PTNB. The consensus includes image‐guided methods, indications, contraindications, multidisciplinary team recommendations, biopsy procedures, daytime/outpatient biopsy, complications, pathological examination, and management of negative results.

Abstract
Molecular biomarkers that predict disease progression might promote drug development and therapeutic strategies in aggressive cancers, such as gastric cancer (GC). High-throughput mRNA sequencing (RNA-seq) revealed that collagen type X alpha 1 (COL10A1) is a disease progression-associated gene. Analysis of 103 GC patients showed that high COL10A1 mRNA expression was associated with GC metastasis and reduced survival. We analyzed the COL10A1 promoter using the UCSC genome website and JASPAR database, and we found potential SOX9 binding site. Here, we demonstrated that SOX9 and COL10A1 were both up-regulated in GC. We observed a positive correlation between the expression patterns of SOX9 and COL10A1 in GC cells and tissues. The results of electrophoretic mobility shift assay (EMSA), chromatin immunoprecipitation (ChIP) assay and promoter reporter indicated that SOX9 could directly bind to the COL10A1 gene promoter and activate its transcription. Biological function experiments showed that COL10A1 regulated the migration and invasion of GC cells. Knockdown COL10A1 inhibited lung and abdominal cavity metastasis in a nude mouse model. Moreover, transforming growth factor-β1 (TGF-β1) treatment up-regulated the phosphorylation of Smad2 and increased SOX9 and COL10A1 expression. COL10A1 was confirmed to be a potential inducer of epithelial-to-mesenchymal transition (EMT). SOX9 was essential for COL10A1-mediated EMT, and cell migration, invasion and metastasis. Co-expression of SOX9 and COL10A1 was associated with tumor progression and was strongly predictive of overall survival in GC patients. In summary, this study elucidated the mechanistic link between COL10A1 and the TGF-β1-SOX9 axis. These findings indicated that COL10A1 might play a crucial role in GC progression and serve as a potential biomarker and therapeutic target in GC patients.

Abstract
Objective: To explore the radiological, pathological features and clinical characteristics of neuroendocrine prostate cancer patients(NEPC). Methods: The clinical characteristics and pathology data of 13 neuroendocrine prostate cancer patients treated in the Affiliated Hospital of Tianjin Medical University from January 2004 to January 2015 were analyzed retrospectively. Results: Of all 13 patients, three cases were primally diagnosed small cell cancer, and 10 cases were translated to neuroendocrine type from adenocarcinoma after endocrine therapy. Frequent urination, urgency, nocturia, and dysuria were main symptoms. Serum prostate-specific antigen (PSA) was (14.5±3.2)μg/L; the volume of prostate was enlarged, mean volume, range 28-176(45±4)ml. The lesion was moderately low signal intensity in T(2)WI, while slightly higher signal in DWI. Signal characteristic of dynamic enhanced MRI was "fast in fast out" . The expression of Synaptophysin, Chromogranin A , CD56 and Ki-67 in NEPC were highly expressed by immunohistochemistry analysis. Among them, five patients accepted intravenous chemotherapy, two cases received external radiation therapy, three cases received cryoablation and three cases received palliative therapy. Median survival time in all 13 patients was 10 months, while median survival time in patients treated by chemotherapy was 16 months . Conclusion: NEPC is a highly aggressive subtype of prostate cancer characterized by rapid disease progression, lack of treatment and worse prognosis. Therefore, patients with NEPC may benefit from early diagnosis and comprehensive treatment with chemotherapy.

Abstract
Introduction Radiofrequency ablation (RFA) is the foremost treatment option for advanced hepatocellular carcinoma (HCC), however, rapid and aggressive recurrence of HCC often occurs after RFA due to epithelial–mesenchymal transition process. Although combination of RFA with sorafenib, a molecular targeted agent, could attenuate the recurrence of HCC, application of this molecular targeted agent poses a heavy medical burden and oral administration of sorafenib also brings severe side effects. Materials and methods In this study, we prepared an apatinib microcrystal formulation (Apa-MS) that sustainably releases apatinib, a novel molecular targeted agent, for advanced HCC treatment. We injected apatinib solution or Apa-MS into subcutaneous HCC tumors. Results It was found that Apa-MS exhibited slow apatinib release in vivo and in turn inhibited the epithelial–mesenchymal transition of HCC cells for extended time. Moreover, in rodent HCC model, Apa-MS enhanced the antitumor effect of RFA treatment. Conclusion Based on these results, we conclude that Apa-MS, a slow releasing system of apatinib, allows apatinib to remain effective in tumor tissues for a long time and could enhance the antitumor effect of RFA on HCC.

INTERNATIONAL JOURNAL OF CLINICAL AND EXPERIMENTAL PATHOLOGY 2018; 11:2522-2529. [PMID: 31938365 PMCID: PMC6958251] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 02/09/2018] [Accepted: 03/23/2018] [Indexed: 06/10/2023] [Imported: 11/05/2023]
Abstract
Increasing studies have revealed the importance of microRNAs (miRNAs) in tumorigenesis and tumor progression. miR-455-3p is a newly identified tumor suppressive RNA in various human cancers. However, the expression pattern and clinical significance of miR-455-3p in colorectal cancer (CRC) remains unclear. We found that expression of miR-455-3p was significantly reduced in CRC tissues and cell lines. In addition, we show that low miR-455-3p expression is associated with larger tumor size, advanced tumor stage, and poorer overall survival of CRC patients. Furthermore, in vitro experiments revealed that overexpression of miR-455-3p represses cell proliferation. Importantly, we show that the tumor protein translationally controlled 1 (TPT1) is a direct target of miR-455-3p. Moreover, expression of TPT1 was inversely correlated with the expression of miR-455-3p. Loss-of-function of TPT1 had a similar effect on CRC cell proliferation in vitro as gain-of-function of miR-455-3p. Taken together, these data suggest that miR-455-3p functions as tumor suppressive RNA by targeting TPT1 in CRC, and it might be a potential therapeutic target for CRC patients.

Abstract
OBJECTIVE Liver metastases occur in approximately 4%-14% of gastric cancer patients and are associated with high mortality. However, no standardized treatment approach is available for these patients. We aimed to assess the clinical outcomes of patients with gastric cancer liver metastases (GCLM) who underwent percutaneous cryoablation. METHODS We retrospectively enrolled 19 patients with 27 metastatic hepatic tumors who underwent cryoablation for liver metastases after gastrectomy for primary gastric cancer. Complications, overall survival (OS), local tumor progression-free survival (PFS), recurrence rates, and quality of life were assessed. RESULTS After cryoablation therapy, the median OS for all 19 patients was 16.0 months (range, 5-50 months), and the 1-, 2-, and 3-year OS rates were 78.9%, 43.4%, and 21.7%, respectively. The median local tumor PFS was 8.0 months (range, 3-24 months), and the local tumor PFS rates at 6 and 12 months were 59.2% and 23.2%, respectively. Overall, patients' quality of life improved after cryoablation therapy (P < 0.05). Complications in this study were mild; no severe complications caused by technique were detected. CONCLUSIONS Cryoablation provided good local control, improved patients' quality of life and had a low complication rate. Our research showed that cryoablation may be an effective palliative treatment for GCLM.

Abstract
Radiofrequency ablation (RFA) is a local-ablative therapy for unresectable hepatocellular carcinoma (HCC). At present, there is no predictive marker for RFA treatment outcomes. This work aimed to valuate myeloid ecotropic viral integration site 1 (MEIS-1) in predicting post-RFA treatment outcomes of unresectable HCC patients. The time to progression (TTP) and overall survival (OS) of 81 HCC patients who received RFA treatment were measured. The protein level of MEIS-1 in tumor specimens was measured by western blot. The role of MEIS-1 in RFA-treating HCC in vivo growth nude mouse model was examined via PET/CT imaging. Higher level of MEIS-1 in tumor tissue is associated with better RFA treatment outcomes. The median TTP was 9.0 (95% confidence interval [CI]: 6.8–11.3) months in patients with high MEIS-1 expression (n = 43) versus 6.0 (95% CI: 4.6–7.4) months in patients with low MEIS-1 expression (n = 38). Moreover, in rodent HCC model we found overexpression of MEIS-1 enhanced the anti-tumor effect of RFA treatment. We conclude that high level of MEIS-1 expression predicts better RFA treatment outcome in HCC.

Abstract
OBJECTIVES To describe immunological consequences induced by cryoablation against H22 cells in vivo. METHODS Adult BALB/c mice underwent subcutaneous implantation of H22 cells. All of them were assigned into three groups randomly: group A (false surgery), group B (cryoablation) and group C (cryoablation plus Freund's adjuvant). Animals were sacrificed 1, 2 and 3 weeks after treatment. Serum IFN-γ and IL-4, Th1/Th2 in spleens and cytotoxicity were detected. RESULTS Compared with that of group A, (1) INF-γ of group B was higher, but IL-4 was lower; cryoablation plus Freund's adjuvant enhanced these effects. (2) Th1/Th2 rose significantly in both group B and group C. (3) Strong cytolytic activity against H22 cells of group B and group C was found on day 7, 14 and 21. CONCLUSIONS Our study showed a marked shift toward Th1 and IFN-γ expression after cryoablation, with an immuno-stimulatory effect against murine H22 hepatoma Cell.

Abstract
Objective To assess the comparative efficacy and safety of combination treatment with transarterial chemoembolization (TACE) for patients with unresectable hepatocellular carcinoma (HCC) through a systematic review and network meta-analysis and to identify what is the best combination treatment with TACE. Materials and Methods A network meta-analysis was used to identify evidence from relevant randomized controlled trials. We searched databases for publications up to June 2017. The prespecified primary efficacy outcomes were treatment response and 6-month to 3-year overall survival (OS), while the secondary efficacy outcomes were 1- and 2-year disease-free survival (DFS); safety outcomes were advance effects of combination treatment. We conducted pairwise meta-analyses using a random-effects model and then performed random-effects network meta-analyses. Results A total of 48 trials were eligible (50 analyses), involving 5627 patients and 19 treatment arms. In comparison with other types of combination therapy arms, network meta-analysis disclosed that TACE + three-dimensional conformal radiotherapy, TACE + percutaneous ethanol injection, TACE + percutaneous microwave coagulation therapy, TACE + percutaneous acetic acid injection, and TACE + sorafenib were the more effective methods in treatment response, 6-month to 3-year OS, and 1–2 year DFS; the adverse effects of TACE + sorafenib were serious. The study was registered with PROSPERO, number CRD42017071102. Conclusions When considering the efficacy, combination therapy with TACE seemed to offer clear advantages for patients with unresectable HCC. TACE + Three-dimensional conformal radiotherapy, TACE + Percutaneous ethanol injection, TACE + Percutaneous microwave coagulation therapy, and TACE + Percutaneous acetic acid injection are likely the best options to consider in the application of combination treatment.
