Active clinical trials for "Liver Neoplasms"

Clinical Trial of Elemene Injection/Elemene Oral Emulsion in Combination with Systematic Chemotherapy including Oxaliplatin in the First -line treatment of advanced primary liver cancer

To evaluate the safety and efficacy of ultrasonography (US) -guided radiofrequency ablation for liver tumors, the investigators used preoperative and postoperative US/CEUS(contrast-enhanced ultrasonography)/CT/MRI to assess lesions, and laboratory tests including the tumor markers to evaluate the general condition of patients. Intraoperative US/CEUS/CT would be applied to monitor ablation lesions.

Patients with HCC with portal vein involvement not involving the bifurcation (vP1-vP3) and no evidence of extra-hepatic spread will be enrolled. Patients will be required to have Child's A liver function and no significant portal hypertension. Patients will be randomly assigned with a 1:1 ratio to either surgery followed by adjuvant sorafenib or sorafenib alone. Patients will be followed by serial imaging. The primary end-point is overall survival.

This study is a non-interventional, observational, prospective, and global participant data registry. The study will collect effectiveness and safety data from approximately 1000 participants with liver cancers treated with TheraSphere® in a real-life setting from multiple centers globally. The absorbed dose to tumor and normal tissue will be calculated using the Simplicit90Y™ software in the subgroup of hepatocellular carcinoma (HCC) participants.

Hepatocellular carcinoma (HCC) is one of the most common malignancies worldwide and is commonly treated with transarterial locoregional therapies (transarterial chemoembolization (TACE) or transarterial radioembolization (TARE)). Early assessment of the effectiveness of transarterial locoregional therapies is critical for treatment planning and early identification of non-responders to allow a timely repeat treatment or conversion to a second-line local-regional or systemic treatment. Response of HCC to transarterial locoregional therapies is usually assessed by changes in tumor contrast material enhancement thought to reflect tumor viability. However, contrast material enhancement may not always accurately indicate tumor response as it may also reflect reactive changes rather than residual tumor tissue. A potential alternative for evaluation of the residual tumor is diffusion-weighted imaging (DWI), which can differentiate between tumor tissue with high cellularity and tumor necrosis. DWI has been shown useful in therapy response assessment of liver tumors. A further development of DWI is intravoxel incoherent motion imaging (IVIM), an MRI technique which also takes tumor perfusion and thus tumor viability into account. This makes IVIM a promising tool for early therapy response assessment in HCC patients. The primary objective is to proof that DWI and especially IVIM with its inherent perfusion information related to tumor neovascularization allows for reliable and quantitative monitoring of tumor response and separating responders from non-responders to either of the two locoregional treatments (TACE or TARE) The secondary objective is to identify whether DWI/IVIM acquired during early follow-up (1 month after treatment) leads to better response assessment than DWI/IVIM acquired during later follow-up (3 months after treatment). The primary outcome will be the DWI/IVIM values in patients responding to transarterial locoregional therapies of HCC compared to patients not responding to therapy according to mRECIST at 6 months The secondary outcome will be the number of patients correctly identified as responders at early follow-up (after 1 month) with DWI/IVIM compared to the number of patients correctly identified as resopnders at later follow-up (after 3 months).

Study design: Prospective, single-center, phase IIa clinical trial; Primary endpoint: Recurrence free survival; Secondary endpoints: Safety, overall survival; Main characteristics of patients: Liver malignancy, required (extended) hemihepatectomy, insufficient liver reserve; Study approaches: The experimental group is treated with ALPPS combined with Tislelizumab, and the control group was treated with ALPPS; Sample size: 20 (10:10); Study process: In experimental group, patients who meet the inclusion criteria will receive ALPPS stage I surgery, treated with Tislelizumab 2-4 weeks after stage I surgery, and receive ALPPS stage II surgery 2-4 weeks after Tislelizumab treatment, and treated with Tislelizumab q3W 6-12 months after stage II surgery; In control group, patients who meet the inclusion criteria will receive ALPPS stage I surgery, and receive ALPPS stage II surgery 3-6 weeks after stage I surgery.

The prognosis of patients with metastatic right-sided colon cancer is worse than that of patients with metastatic left-sided cancer. Different guidelines have different recommendations on specific conversion therapy for colorectal liver metastases. The United States NCCN guidelines do not recommend standard chemotherapy combined with anti EGFR monoclonal antibody for patients with right colon cancer. The European ESMO guidelines recommend that patients with Ras / BRAF wild-type right-sided colon cancer should first consider three drugs ± bevacizumab, but considering the objective response rate results, standard chemotherapy + anti EGFR monoclonal antibody is still one of the choices. China CSCO guidelines recommend standard chemotherapy ± bevacizumab, and also recommend standard chemotherapy + cetuximab for patients with right-sided colon cancer. Therefore, the targeted therapy for RAS / BRAF wild-type metastatic right colon cancer is still controversial. Therefore, we are ready to carry out the clinical trial of cetuximab and bevacizumab in conversion therapy for RAS / BRAF wild-type metastatic right colon cancer. The conversion resection rate is the primary point, and the objective response rate, perioperative safety and long-term survival are the secondary points.

The investigators assessed whether the addition of a preoperative regimen of Bevacizumab regimen to improves R0 resection rate and survival among patients with potentially resectable gastric cancer with liver metastasis.

The purpose of this research is to compare the classical procedure with intrahepatic Glisson's approach for laparoscopic anatomical hepatectomy. The validity, feasibility and limitations were assessed objectively through our clinical prospective study. The investigators expect laparoscopic anatomical hepatectomy with intrahepatic Glisson's approach is safe, effective and feasible.

In this study, the investigators assessed the effect of Cetuximab in combination with chemotherapy in the treatment of unresectable metastatic colorectal cancer.
