RESUMO

Purpose: The aim of this study was to explore a radiomics-clinical model for predicting the response to initial superselective arterial embolization (SAE) in renal angiomyolipoma (RAML). Materials and methods: A total of 78 patients with RAML were retrospectively enrolled. Clinical data were recorded and evaluated. Radiomic features were extracted from preoperative contrast-enhanced CT (CECT). Least absolute shrinkage and selection operator (LASSO) and intra- and inter-class correlation coefficients (ICCs) were used in feature selection. Logistic regression analysis was performed to develop the radiomics, clinical, and combined models where the fivefold cross-validation method was used. The predictive performance and calibration were evaluated by the receiver operating characteristic (ROC) curve and calibration curve. Decision curve analysis (DCA) was used to measure clinical usefulness. Results: The tumor shrinkage rate was 29.7% in total, and both fat and angiomyogenic components were significantly reduced. In the radiomics model, 12 significant features were selected. In the clinical model, maximum diameter (p = 0.001), angiomyogenic tissue ratio (p = 0.032), aneurysms (p = 0.048), and post-SAE time (p = 0.002) were significantly associated with greater volume reduction after SAE. Because of the severe linear dependence between radiomics signature and some clinical parameters, the combined model eventually included Rad-score, aneurysm, and post-SAE time. The radiomics-clinical model showed better discrimination (mean AUC = 0.83) than the radiomics model (mean AUC = 0.60) and the clinical model (mean AUC = 0.82). Calibration curve and DCA showed the goodness of fit and clinical usefulness of the radiomics-clinical model. Conclusions: The radiomics-clinical model incorporating radiomics features and clinical parameters can potentially predict the positive response to initial SAE in RAML and provide support for clinical treatment decisions.

RESUMO

OBJECTIVE: To detect the effects of active compounds of Caodoukou () (ACAK) on the proliferation, migration and invasion of pancreatic cancer, and explain the possible molecular mechanism of ACAK interacting with these processes. METHODS: Cell counting kit-8 method, cell scratch repair experiment, Transwell migration and invasion experiment, immunohistochemistry, western blot assay and real-time polymerase chain reaction experiment were used to evaluate the effect of ACAK on the proliferation, migration and invasion of pancreatic cancer cells. The levels of active molecules involved in the phosphoinosmde-3-kinase (PI3K)/Akt/the mammalian target of rapamycin (mTOR) signal transduction were detected by Western blot assay. In addition, the function of ACAK was evaluated by xenotransplantation tumor model in nude mice. RESULTS: The inhibitory effect of ACAK on the proliferation of pancreatic cancer cells showed certain time-dose dependence. The results of scratch repair test, Transwell test, Western blotting and real time polymerase chain reaction assay showed that ACAK could inhibit the migration and invasion of pancreatic cancer cells . In addition, the regulatory effect of ACAK on epithelial-mesenchymal transition (EMT) is partly attributed to PI3K/Akt/mTOR signaling pathway. The experimental results showed that ACAK regulated the development of pancreatic cancer. CONCLUSIONS: ACAK can partly inhibit the activity of EMT and matrix metallopeptidases by down-regulating the downstream proteins of PI3K/Akt/mTOR signal pathway, thus inhibiting the ability of migration and invasion of pancreatic cancer.

RESUMO

Laryngeal squamous cell carcinoma (LSCC) is an aggressive and lethal malignant neoplasm with extremely poor prognoses. Accumulating evidence has indicated that preferentially expressed antigen in melanoma (PRAME) is correlated with several kinds of cancers. However, there is little direct evidence to substantiate the biological function of PRAME in LSCC. The purpose of the current study is to explore the oncogenic role of PRAME in LSCC. PRAME expression was analyzed in 57 pairs of LSCC tumor tissue samples through quantitative real-time PCR, and the correlation between PRAME and clinicopathological features was analyzed. The result indicated that PRAME was overexpressed in the LSCC patients and correlated with the TNM staging and lymphatic metastasis. The biological functions and molecular mechanism of PRAME in LSCC progression were investigated through in vitro and in vivo assays. Functional studies confirmed that PRAME facilitated the proliferation, invasion, migration, and epithelial-mesenchymal transition of LSCC cells, and PRAME also promoted tumor growth in vivo. HDAC5 was identified as an upstream regulator that can affect the expression of PRAME. Moreover, PRAME played the role at least partially by activating PI3K/AKT/mTOR pathways. The above findings elucidate that PRAME may be a valuable oncogene target, contributing to the diagnosis and therapy of LSCC.

RESUMO

OBJECTIVE: To evaluate the effects of the Wenshen Jianpi recipe (, WJR) on immune reconstruction and natural killer (NK) cells in immunological non-responders (INRs) of people living with human immunodeficiency virus (HIV) (PLWH) and propose new therapeutic strategies for HIV. METHODS: Based on Traditional Chinese Medicine treatment principle "invigorating and warming in the spleen and kidneys", WJR combined with antire-troviral therapy (ART) therapy was performed in a randomized, double-blind, placebo-controlled study of 60 patients with non-responders. The randomized process was executed by the Clinical Evaluation Center of China Academy of Chinese Medical Sciences. Sixty patients who met the inclusion criteria obtained random numbers (that is the drug number) was randomly divided into a treatment group and a placebo control group according to a 1∶1 ratio. CD4+T cell counts and natural killer (NK) cells counts were evaluated at baseline and 12-week, 24-week follow-ups. RESULTS: Four participants received random numbers and did not enter the group due to the patient's own reasons. A total of 56 patients were enrolled, including 28 in the treatment group and 28 in the control group. CD4+T cell counts in the treatment group were significantly increased at week 24 ( = 0.01 < 0.05), which were significantly higher than those in the control group (= 0.01 < 0.05). Although no significant differences were observed between two groups, the CD56briCD16- NK cell counts in the treatment group were significantly increased after duration. and CD56dimCD16+ NK cell counts in the treatment group were significantly higher than those in the control group after 24 weeks of treatment (= 0.025 < 0.05). As compared with the control group, the treatment group had significantly lower CD56negCD16+ NK cell counts after 24 weeks of treatment (= 0.023 < 0.05). CONCLUSIONS: WJR promotes the immune reconstruction of INRs and redistribution of NK cell subsets, notably decreasing CD56negCD16+ NK cell counts in INRs. However, the redistribution of NK cell subsets is not beneficial for immune reconstruction in INRs. Further large-scale RCTs are required to evaluate the effect of WJR on immune recovery in INRs and decipher the underlying mechanism.

RESUMO

To observe the efficacy of Gouty Tea on chronic gouty arthritis and its effect on vascular endothelial function and inflammatory factor levels. Totally 120 patients with chronic gouty arthritis were divided into control group (allopurinol orally, 100 mg/time, tid, for 12 weeks) and observation group (Gouty Tea, 1 bag/time, tid, for 12 weeks) randomly (n=60 per group). Compared with those before treatment, the TCM symptom scores, visual analogue score (VAS) and the levels of UA and XOD of the two groups were reduced, while the levels of NO, ET-1, VEGF, vWF, CRP, IL-1ß, TNF- α and NALP3 of the two groups improved, 6 and 12 weeks after treatment (P< 0.05). Nevertheless, after 6 weeks of treatment, there were no significantly difference of the level of VAS between the two groups. After 12 weeks of treatment, in the observation group, VAS was significantly lower compared to the control group. The TCM symptom scores and the levels of UA and XOD were significantly lower, while the levels of NO, ET-1, VEGF, vWF, CRP, IL-1ß TNF- α and NALP3 were significantly better in the observation group than those of the control group 12 weeks after treatment (P< 0.05). The total effective rate was significantly higher and the incidence of adverse reactions was significantly lower in the observation group compared to the control group (P< 0.05). Gouty Tea can effectively reduce the UA, XOD levels and VAS, effectively improve the vascular endothelial function and inhibit the inflammation of patients.

RESUMO

Frequent oil spill accidents and industrial wastewater discharge has always been one of the most severe worldwide environmental problems. To cope with this problem, many fluorine-containing and high-cost materials with superwettability have been extensively applied for oil-water separation, which hinders its large-scale application. In this work, a novel human hair fiber (HHF)-polymerized octadecylsiloxane (PODS) fiber was fabricated with a facile one-pot dip-coating synthesis approach, inspired by the self-assembly performance and hydrophobicity of OTS modification. The benefits of prominent hydrophobic/lipophilic behavior lie in the low surface energy, and a rough PODS coating was rationally adhered on the surface of HHF. Driven solely by gravity and capillary force, the HHF-PODS showed excellent oil/water separation efficiency (> 99.0%) for a wide range of heavy and light oil/water mixtures. In addition, HHF-PODS demonstrated durability toward different harsh environments like alkaline, acid, and salty solutions.

RESUMO

The present study aimed to investigate LINC00278 expression in laryngeal squamous cell carcinoma (LSCC) and its involvement in the process of proliferation, migration, and invasion, providing a rationale for mining potential diagnostic and therapeutic targets of LSCC. Univariate and multivariate Cox regression analyses were performed to identify optimal prognostic lncRNAs. MTS, colony formation, wound healing, and Transwell invasion assays were used to determine the effects of LINC00278 overexpression on the proliferation, migration, and invasion of cancer cells. The expressions of signaling pathway-related proteins and epithelial-mesenchymal transition (EMT) marker proteins were detected using western blot. The chromatin immunoprecipitation (ChIP) and dual-luciferase reporter assays were performed to demonstrate the binding of ETS proto-oncogene 1, transcription factor (ETS1), and LINC00278 promoter region. The molecular targets of LINC00278 were identified by RNA sequencing analysis and co-expression analysis. Kaplan-Meier analysis and CIBERSORT algorithm were used to analyze survival and immune cell infiltration based on LINC00278, COL4A1, and COL4A2. Multivariate Cox regression was used to establish a six-gene prognostic model. LINC00278 expression was low in LSCC tissues, and it was significantly associated with the TNM (tumors/nodes/metastases) stage (p<0.001), lymphatic metastasis (p<0.01), and pathological differentiation (p<0.01). LINC00278 overexpression significantly reduced LSCC cell proliferation, migration, and invasion in TU686, TU177, and AMC-HN-8 cell lines. E-cadherin protein expression was increased, while N-cadherin, Vimentin, Zeb1, and Snail protein expression was decreased in the LINC00278 group, compared to the pcDNA3.1 group. Additionally, in AMC-HN-8 and FaDu cell lines, the LINC00278-treated group had significantly lower p-AKT and p-mTOR protein levels than the control group. ETS1 is a direct transcriptional regulator of the LINC00278 gene based on luciferase reporter assays and ChIP experiments. Western blot analysis demonstrated that high LINC00278 expression inhibited both ETS1 expression and phosphorylation. COL4A1/COL4A2 were identified as potential downstream targets of LINC00278. Meanwhile, the LINC00278/COL4A1/COL4A2-dominated low-risk group showed higher antigen-presenting activity and a higher immune score than the high-risk group. The findings indicated that ETS1 upregulated LINC00278 expression on the Y chromosome, which in turn inhibited LSCC growth in vivo and in vitro by inhibiting the AKT/mTOR signaling pathway via downregulation of COL4A1/COL4A2.

RESUMO

This study aimed to elucidate the potential genes of the matrix metalloproteinase (MMP) family, responsible for the progression of laryngeal squamous cell carcinoma (LSCC). Besides, we ascertained the changes in common malignant behaviors in vitro by knocking down MMP1. TCGA, GEO, Oncomine, and microarray data were conducted to analyze the expression levels of MMPs and to find tissue-specific genes in LSCC. Univariate and multivariate Cox regression analyses were established in the construction of a prognostic model based on expression profiles and clinical information of LSCC in TCGA. We then comprehensively analyzed survival, co-expression network, and immune infiltration based on a prognostic model by Kaplan-Meier analysis, WGCNA, and CIBERSORT. Thereafter, qRT-PCR, proliferation, Transwell, and wound-healing assays were used to assess the accuracy of the bioinformatics data. A total of seven genes in the MMP family were identified as differentially expressed genes (DEGs) by integrating three public databases and microarray data. Additionally, multivariate Cox regression was used to establish a four-gene (MMP1/3/8/10) prognostic model, which exhibited a better predictive accuracy than the TNM (tumors/nodes/metastases) based model. The prognostic model was related to plasma cells, CD8+ T cells, follicular helper T cells, resting NK cells, and M0 macrophages infiltration. The expression of MMP1, MMP3, and MMP10 was the highest in head and neck squamous cell carcinoma (HNSC) compared to other cancer in the Oncomine and GEPIA dataset. Further, MMP1 demonstrated significant upregulation in 40 paired LSCC tissues. Eventually, MMP1 downregulation inhibited cell viability, colony formation, and cell migration in TU686 and FaDu cells. Our findings suggest that the four-gene signature might be associated with the prognosis. Further, we revealed that MMP1 is a pivotal biomarker for the biotherapy and prognostic evaluation of patients with LSCC.

RESUMO

BACKGROUND: We aim at investigating the correlation between skip N2 metastases (SN2) and SUVmax, long diameter of tumor mass after 18F-FDG PET/CT, and pathological Ki67 expression in patients with non-small-cell lung cancer (NSCLC). METHODS AND RESULTS: We retrospectively analyzed the factors that might affect the pathogenesis of SN2 in these patients. The clinical SN2 symptoms in patients with squamous carcinoma or adenocarcinoma were investigated. The work curve was utilized to analyze the optimal cutoff value for the SUVmax and long diameter of tumor. Multivariate analysis revealed that high expression of Ki67 was a risk factor for mediastinal SN2 (OR = 1.042, 95% CI: 1.009-1.076). Subgroup analysis indicated that the SUVmax of the non-SN2 group was significantly higher than that of the SN2 group in patients with squamous carcinoma (16.3 ± 6.0 vs. 10.7 ± 5.6, P = 0.026). In the patients with adenocarcinoma, the long diameter of tumor in the SN2 group was significantly longer than that of the non-SN2 group (43.8 ± 16.3 mm vs. 30.1 ± 13.8 mm, P = 0.032). The Ki67 expression in the SN2 group was significantly higher than that of the non-SN2 group (51.7 ± 24.0 vs. 30.0 ± 19.2, P = 0.028). CONCLUSIONS: The differences of clinical features of the patients in the SN2 group and non-SN2 group in the NSCLC patients were associated with the pathological subtypes, which were featured by lower SUVmax in the SN2 of the squamous carcinoma, and longer diameter of SN2 in the adenocarcinoma patients.

RESUMO

Although HER2-targeted therapy has been shown to prolong the survival of patients with HER2-positive breast cancer, most patients eventually progress due to drug resistance. Novel treatment options are urgently needed to overcome resistance to HER2-targeted therapy. The VEGF/VEGFR (Vascular endothelial growth factor and its receptors) pathway is essential in tumor angiogenesis, which may be a promising target in HER2-positive breast cancer providing a rationale for the use of tyrosine kinase inhibitors (TKIs) targeting VEGFR. Here, we present a case of a heavily pretreated advanced breast cancer patient who did not respond to HER2-targeted therapy and developed resistance to multiple lines of HER2-targeted treatment. The patient was treated with apatinib at a dose of 500 mg daily, and obtained partial remission (PR) with a progression-free-stage (PFS) of 6 months. Our case indicates that apatinib might have anti-tumor activity in patients with HER2-positive breast cancer with HER2-targeted resistance. This case is of value which may provide new insights into strategies for HER2-targeted therapy resistance options in the clinic.

RESUMO

Intestinal mono-carboxylate transporter 1 (MCT1) plays an important role in the oral absorption of short-chain fatty acids that were used as oxidative metabolite. However, the prodrug strategy targeting intestinal MCT1 for oral delivery is rarely exploited. The oral bioavailability of Gemcitabine (Gem) is low mainly due to its poor intestinal permeability and rapid metabolism. Herein, a facile di-acid mono-amidation strategy was firstly developed to target MCT1 for oral chemotherapy. The N4-amino group of Gem is mono-amidated with di-acids containing different carbon chain lengths, which could recognize intestinal MCT1 and are bio-activated at physiological pH independent of the hydrolysis enzymes. The adipic acid-Gem shows higher MCT1 affinity, better gastrointestinal tract stability (3-fold), improved oral bioavailability (8.8-fold), and less gastrointestinal toxicity in comparison to Gem. Moreover the bio-activation rate of the prodrugs decreases with the increased fatty acid chain length of the linkage under physiological conditions. In summary, we present the first evidence that MCT1 could act as a new target for oral prodrug delivery, and that the linkage could modify the bio-activation rate for achieving optimal oral bioavailability. Our findings provide novel knowledge to rationally design intestinal transporter-targeting oral carrier prodrug.

RESUMO

The prognostic value of tumor characteristics for glioma has been controversial, partly because of a lack of knowledge about how these associations develop. Extent of resection may be factors that mediate the relationship between tumor characteristics and the hazard of death from glioma. Patients and Methods: This consecutive study retrospectively included a group of 393 treatment-naive patients with newly, pathologically confirmed glioma between January 2004 and December 2014. Information on patient age, gender, Karnofsky Performance Status (KPS), tumor grade, tumor size, tumor location, presence or absence of contrast enhancement on MRI and extent of tumor resection have all been collected. The discrete-time survival model integrating survival outcomes within structural equation models was employed to develop and evaluate a comprehensive hypothesis regarding the direct and indirect impact of tumor characteristics on the hazard of death from glioma, mediated by the extent of resection. Results: Except for tumor location, the indirect effects of tumor grade, contrast enhancement, and tumor size on PFS of glioma through extent of resection were found significant in the model. Conclusion: This study provides a better understanding of the process through which tumor characteristics is associated with hazard of death from glioma.

RESUMO

Introduction: The first-line treatment for gastric variceal rebleeding in cirrhotic patients is endoscopic cyanoacrylate injection. We focused on the efficacy and prognosis of cyanoacrylate combined with Lauromacrogol® for gastric varices (GV) in a retrospective study of long-term follow-up. Materials and Methods: One hundred thirty patients with cirrhosis and GV from March 2011 to February 2013 were included. Sixty-eight patients underwent endoscopic cyanoacrylate injection with Lauromacrogol and 62 patients without Lauromacrogol. The median follow-up was 40.1 and 38.8 months, respectively. Results: The volumes of cyanoacrylate used for the GV eradication in the Lauromacrogol group were significantly lower than those in the Ethiodol® group (1.6 ± 0.8 versus 2.1 ± 1.2 mL, P = .029). No ectopic embolisms were observed during follow-up. The 1- and 3-year rebleeding-free rate did not differ between groups (83.7% and 59.2% versus 75.8% and 62.5%; P = .797). The same was observed for mortality (86.6% and 83.5% versus 85.5% and 83.7%; P = .955). New portal venous thrombosis (PVT) and progression of previous partial PVT were independently associated with rebleeding (hazard ratio [HR] 5.127, 95% confidence interval [CI], 2.430-10.817, P = .000) and death (HR 10.093, 95% CI, 3.988-25.548, P = .000). Conclusions: Endoscopic cyanoacrylate injection with Lauromacrogol might minimize the required dosage of cyanoacrylate, but it did not improve rebleeding rate or survival. Exacerbation of PVT was associated with rebleeding and death.

RESUMO

OBJECTIVE: This study was performed to determine the relationship between the minimum distance from the radiofrequency ablation (RFA) needle tip to the tumor and local tumor progression (LTP) of hepatocellular carcinoma (HCC) nodules and identify prognostic factors for LTP. METHODS: We reviewed 197 patients (197 nodules) who underwent RFA after transcatheter arterial chemoembolization for HCC from January 2010 to January 2015. Three-dimensional registration of images was used to calculate the minimum distance from the tip to the tumor. We then divided the minimum distance into two groups: <2 and ≥2 mm. Contrast-enhanced computed tomography was performed after treatment. The LTP rate was calculated 1 and 3 years after RFA. We performed multivariate analysis to identify independent prognostic factors for LTP. RESULTS: The cumulative 1-year LTP rates in the <2- and ≥2-mm groups were 82.7% and 4.3%, respectively, and the cumulative 3-year LTP rates in the two groups were 94.8% and 10.8%, respectively. The minimum distance from the needle tip to the tumor was an independent prognostic factor for LTP. CONCLUSIONS: A minimum distance of 2 mm from the needle tip to the tumor should be completely ablated along with the tumor.

RESUMO

OBJECTIVE: This study aimed to determine if superselective renal artery embolization is a safe and effective method of treating bleeding complications after percutaneous renal biopsy. METHODS: From January 2006 to December 2017, 43 patients (22 men and 21 women, mean age: 44.5 ± 14.0 years) underwent angiography for post-biopsy bleeding complications following percutaneous biopsy. Patients underwent angiography and superselective artery embolization. We recorded serum creatinine and hemoglobin values to assess the effect of embolization. RESULTS: Successful embolization was achieved in all patients. There was a pseudoaneurysm in 10 cases, arteriovenous fistula in eight, contrast media extravasation in 16, arteriovenous fistula combined with contrast media extravasation in five, and pseudoaneurysm combined with arteriovenous fistula in four. The embolic substance was a microcoil only or combined with a gelatin sponge. The mean creatinine value was not different at 1 day and 1 week after embolization compared with before embolization. Mean hemoglobin values were significantly higher at 1 day and 1 week after embolization than before embolization. CONCLUSIONS: Superselective renal artery embolization is a safe and effective treatment for post-biopsy bleeding complications after percutaneous renal biopsy. Lumbar or iliolumbar artery angiography is necessary if renal arteriography shows no signs of hemorrhage.

RESUMO

Metadherin (MTDH) is a multifunctional oncogene involved in tumor cell migration and metastasis through regulating a number of oncogenic signaling pathways in various human malignancies. Previous studies have demonstrated that MTDH is overexpressed in human colorectal cancer (CRC) and associated with cancer progression and a poor prognosis. However, the underlying mechanisms remain largely unknown. The present study investigated the expression and role of MTDH in CRC cells as well as the underlying mechanism of this. Western blot analysis and quantitative polymerase chain reaction were conducted to determine protein and mRNA expression of MTDH in three human CRC cell lines. A short hairpin RNA (shRNA) targeting MTDH was introduced into CRC HCT116 cells to stably inhibit MTDH expression. A Cell Counting Kit­8 assay, colony formation assay, Transwell assay and flow cytometry were used to investigate the effect of MTDH­knockdown on cell proliferation, migration, apoptosis and cell cycle arrest. Western blotting was performed to examine the protein expression levels of cell growth­ and apoptosis­associated genes. The results demonstrated that MTDH was commonly expressed in CRC cell lines. MTDH silencing significantly suppressed cell growth, colony forming ability and migration while inducing the apoptosis of HCT116 cells. In addition, MTDH depletion induced S phase cell cycle arrest in HCT116 cells. Mechanistically, knockdown of MTDH markedly downregulated the expression of phosphorylated protein kinase B, c­Myc, proliferating cell nuclear antigen and B­cell lymphoma 2 (Bcl­2) protein in HCT116 cells, and the expression of p53 and Bcl­2­associated X protein was significantly increased compared with the negative control shRNA group (P<0.05), suggesting that MTDH may function through the expression of numerous types of apoptosis­associated and signaling channel proteins in CRC cells. Taken together, these data indicated that MTDH may serve as a biomarker and candidate therapeutic target for CRC.

RESUMO

This work aims to study the roles and related mechanisms of six2 in 5-FU sensitivity of hepatocellular carcinoma (HCC) cells. KM-Plotter analysis showed that HCC patients with higher six2 expression levels had shorter overall survival. Six2 expression was higher in clinical HCC tissues than in normal tissues, and was negatively correlated with E-cadherin expression. Additionally, six2 overexpression decreased the sensitivity of HCC cells to 5-Fu, characterized as attenuating 5-FU-induced cell apoptosis and downregulation of cell viability, and promoted HCC cells stemness. Mechanistically, six2 overexpression repressed E-cadherin expression via stimulating promoter methylation of the E-cadherin. And E-cadherin overexpression rescued six2-induced decrease of 5-FU sensitivity and promotion on HCC cells stemness. Therefore, our results suggest that Six2 is negatively correlated with good prognosis and decreases 5-FU sensitivity via suppressing E-cadherin expression in HCC cells.

RESUMO

Chronic obstructive pulmonary disease (COPD) is able to be treated and delayed. Many interventions include smoking cessation and daily maintenance of drug therapy. In clinical practice, although respiratory physicians have given optimal drug treatment to patients, there is no treatment for etiological factors in these treatments, and they have little effect on the long-term prognosis of COPD. Therefore, this paper puts forward a method of continuing care. Through Meta analysis of the therapeutic effects of statins, it is shown that statins have a positive impact on the treatment of chronic obstructive pulmonary disease. On the other hand, the study shows that continuing care can reduce the SGRQ (St George's respiratory questionnaire) score of the patient, thereby improving the patient's quality of life. Therefore, both drug therapy and continuing care are effective methods for the treatment of chronic obstructive pulmonary disease, which can be effectively combined.

RESUMO

Objective This study was performed to determine whether transarterial chemoembolization (TACE) plus multi-imaging-guided radiofrequency ablation (MIG-RFA) can completely eliminate 3.1- to 5.0-cm hepatocellular carcinoma (HCC) nodules and identify factors that may influence the complete elimination rate (CER) of this therapy. Methods Patients who underwent TACE+MIG-RFA for initial treatment of HCC from January 2008 to January 2016 were retrospectively reviewed. In total, 162 patients with 216 HCC nodules (3.1-5.0 cm) were enrolled. TACE was performed first; MIG-RFA was performed 2 to 4 weeks later. Contrast-enhanced computed tomography was performed 1, 3, 6, and 12 months after TACE+MIG-RFA. If tumor enhancement was not detected by the end of the 12-month follow-up, the lesion was considered completely eliminated. Additional TACE+MIG-RFA was performed for residual lesions. The CER was calculated 12 months after the last therapy. Factors that may influence the CER were analyzed. Results In total, 207 (95.8%) nodules showed no residual lesions and were completely eliminated after one or more TACE+MIG-RFA sessions. Nine (4.2%) nodules were incompletely eliminated even with repeated TACE+MIG-RFA. Tumor location was the only significant prognostic factor influencing the CER. Conclusions TACE+MIG-RFA can eliminate 3.1- to 5.0-cm HCC nodules; the tumor location may affect the treatment outcome.
