Active clinical trials for "Liver Neoplasms"

CT-guided microwave ablation is one of the important treatment methods for primary or metastatic liver tumors. It has the advantages of minimally invasive, safe, and economical. For liver tumors with a diameter of less than 3 cm, it can be comparable to surgical resection. However, different doctors have different levels of experience, leading to a high risk of residues after ablation and even complications. The key is to fail to plan the needle placement reasonably. The past research on path planning was mostly conducted by the engineering team, so that the actual clinical needs were not considered comprehensively, and the sample size of verified cases was small, which limited the application of existing models in the clinical application. In previous study, we used artificial intelligence to segment the upper abdominal organs and construct the constraint function to establish the ablation path planning model, and initially verified the effectiveness of the path planning model in a small number of cases. Now it is planned to expand the number of patients enrolled to evaluate the accuracy of the ablation path planning model that we have established.

The goal of this observational study is to learn about breast cancer liver metastasis in patients who met the following criteria: female; be ≥ 18 years of age on the day of signing informed consent; confirmed diagnosis of breast cancer liver metastases. Newly diagnosed patients with de-novo liver metastases are eligible; be planned for liver surgery. The main questions it aims to answer are: To characterize the tumour cells and their microenvironment in the liver metastases at the transcriptomic and protein single-cell level; To determine the levels and patterns of immune infiltrates in liver metastases from BC patients; To identify biological features associated with the histopathological growth patterns in liver metastases. To create patient-derived xenografts (PDX) and organoids (PDO) from liver metastases isolated from patients with BC; To perform a histopathological and molecular comparison of liver metastases, PDX and PDO isolated from the same patient Participants will be willing and able to provide written informed consent for this study and tissue samples for research purposes.

Patient Registry aiming to provide regional evidence documenting the clinical merit of EUS (Endoscopic_ Ultrasound) guided liver biopsy, per local standard of practice, in patients with suspected liver disease indicated for an endoscopic intervention and a liver biopsy.

This is a single-arm, open-label, multi-center early phase II study. This proof of concept study will investigate whether the combined use of local tumor ablation/radiation plus immunomodulating drugs may induce a significant immune response in patient with incurable liver metastases from colorectal cancer (CRC) (+/- limited extrahepatic disease) being stable or in partial remission after completion of 4-6 months first line systemic therapy. The primary objective of the study is to show an overall response rate of lesions not treated by ablation/radiotherapy including the extrahepatic lesions (according to iRECIST criteria) higher than 10%. With the continuation of first line systemic treatment, no further responses are expected. Secondary objectives are: To establish the feasibility and safety of the combined treatment modalities; To study the impact of the local technique (RFA/Radiotherapy) on the results; To investigate biomarkers to predict response to the combined treatment

The purpose of this study is to evaluate the safety and efficacy of HepaSphere interventional therapy using digital subtraction angiography（DSA） for liver cancer.

The primary purpose of this study is to demonstrate the safety and effectiveness of using an intra-operative ultrasound contrast agent(Definity®) for the identification of known liver tumors.

RATIONALE: Chemoembolization kills tumor cells by blocking the blood flow to the tumor and keeping chemotherapy drugs near the tumor. Radioembolization kills tumor cells by blocking the blood flow to the tumor and keeping radioactive substances near the tumor. It is not yet known which treatment regimen is more effective in treating patients with liver cancer. PURPOSE: This randomized phase II trial is studying radioembolization to see how well it works compared with chemoembolization in treating patients with liver cancer that cannot be treated with Radiofrequency Ablation or removed by surgery.

This phase I trial is studying the side effects and best dose of cixutumumab when given together with sorafenib tosylate in treating patients with advanced liver cancer. Monoclonal antibodies, such as cixutumumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Sorafenib tosylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving cixutumumab together with sorafenib tosylate may kill more tumor cells.

RATIONALE: Sorafenib tosylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth or by blocking blood flow to the tumor. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Chemoembolization kills tumor cells by blocking the blood flow to the tumor and keeping chemotherapy drugs near the tumor. PURPOSE: This phase I trial is studying side effects and best dose of sorafenib tosylate when given together with chemoembolization in treating patients with unresectable liver cancer.
