Filter by:This is a prospective study to determine the optimal technique for obtaining liver tissue with a smaller caliber (22 gauge) needle and whether a good core biopsy can be obtained without the use of suction and secondly to determine the diagnostic yield and safety of 22 g Fine Needle Biopsy needle for liver biopsy.
The focus of the study is to identify viral factors and host immune responses that differentiate HBV-related HCC patients from HBV patients who have not progressed to HCC. To that end, the investigators will compare gene expression levels between HCC patients and non-HCC patients categorized into high and low risk profiles. The investigators will perform ANOVA to compare three groups (HCC, high risk, low risk). Multiple comparison corrections will be performed using Benjamini and Hochberg False Discovery Rate (FDR) with a 90% confidence that the discovery lists will contain no more than 5% false positives (FDR<0.05) (PMID: 12584122, 11682119). A p-value <0.05 is considered statistically significant using this multiple comparison correction approach. Post-hoc Student-Newman-Keuls or Tukey tests will be used following ANOVA for comparisons of HCC patients with high risk and low risk. If data are not normally distributed when log-transformed, then Kruskall-Wallis tests will be used. ANCOVA will be used to adjust for the effects of covariates, such as age, gender, and HBV genotype (B or C). Further, the investigators often use an additional 2-fold change criterion for significance because the investigators consider a fold change of this magnitude to be biologically significant. Hierarchical clustering analyses and principal component analyses will be used to visualize how well the genes separate the groups, or to discover new subgroups. For the analysis of SNVs, the exact binomial test will be performed and p-values will be adjusted by the Benjamini-Hochberg correction.
The purpose of this study is to evaluate the safety and efficacy of Radiopaque Microsphere (T-ACE Beads with doxorubicin) interventional therapy for patients with liver cancer
The research aims to the primary hepatic carcinoma patients whose diameter of the single tumor is equal or less than 5cm.By supervising the changes of liver function, Child-Pugh score, ICG-R15 value, secondary reaction, incidence rate of RILD during and after the radiotherapy, meanwhile combining the outcome of the progression of disease and the condition of survival quality, the optimum proposal could be obtained and apply to clinic thus make the treatment safe, effective and personalized.
Observational study to evaluate, under real-world practice conditions, the safety and effectiveness of regorafenib in patients diagnosed with unresectable hepatocellular carcinoma (uHCC)
Hepatocellular carcinoma (HCC) is unique regarding diagnosis because the clinical diagnosis without pathology proof is accepted. The dynamic image, including contrast-enhanced computed tomography (CECT) and contrast-enhanced magnetic resonance image (CEMRI) were recognized in many guidelines for diagnosing the HCC. In contrast to the CT and MRI, ultrasound (US) with/without contrast is suggested by several societies as the sufficient surveillance modality. The contrast-enhanced ultrasound (CEUS) has aroused more attentions regarding the rapid improvement of contrast medium. In this study, the investigators conducted a prospective, single-center, open-label trial to compare the efficacy and safety of CEUS + CEMRI in characterizing HCC, in comparison with CECT + CEMRI.
Colorectal cancer is the third most frequently diagnosed cancer and the third leading cause of cancer related deaths in Taiwan. Of the 10,248 new colorectal patients diagnosed each year approximately 60% will develop liver metastasis during the course of their disease. In approximately 30% of these patients who develop liver metastasis the metastatic disease will remain confined to the liver. For the 70-75% of colorectal patients with colorectal liver metastasis not suitable for hepatic resection or similarly ablative therapy with curative intent, systemic chemotherapy is the standard initial management. However, after a patient has failed first- line and in some cases second-line chemotherapy, response rates fall to as low as 12% (Chen HX 2006). Transarterial chemoembolization (TACE) with microsphere is an alternative treatment because normal liver tissue receives most of its blood supply from the portal vein, while colorectal liver metastases derive most of their flow from the hepatic artery. Several clinical trials have explored the feasibility and the efficacy of TACE with microsphere as a treatment for patients with colorectal liver metastasis. HepaSphere represents a novel drug delivery system for chemoembolization, which can add two benefits to embolization therapy. First, by ionically binding the doxorubicin throughout the microspheres, more drug can be delivered into the tumor, with less escape into peripheral circulation. Second, conformability to the architecture of the vessel lumen, providing more contact surface area with the embolic material and the vessel intima, leading to a more complete occlusion. However, there are limited experiences in using HepaSphere TACE for colorectal liver metastasis in Taiwan. In this pilot study, we will evaluate the initiate safety and efficacy of Hepasphere microspheres loaded with a chemotherapeutic agent doxorubicin for the treatment of patients who have failed first-line and second-line systemic chemotherapy.
Selective Internal Radiation Therapy (SIRT), also known as radioembolisation, is a minimal invasive, endovascular treatment for primary and secondary liver tumours. In France, SIR-Spheres are listed as reimbursable by the national health authorities (Haute Autorité de Santé [HAS]). In order to evaluate the reimbursement after five years, all patients treated with SIR-Spheres will be entered into a registry that collects data on the real-life clinical application of SIRT and reports to the national authorities.
The aim of this study is the synergistic effect of cancer ablation and life information rehabilitation therapy on unresectable liver cancer.
Mechanical ventilation can be used to impose a completely regular pattern of breathing frequency and inflation volume on the patient for as long as required. This would considerably improve the reproducibility of the internal motion parameters, and thus facilitate the implementation of respiratory-synchronized techniques such as gating, tracking and four-digital optimization.
