Active clinical trials for "Liver Neoplasms"

This is a single institution, open-label, multi-arm, pilot study of a personalized neoantigen-based dendritic cell (DC) vaccine combined with microwave ablation in subjects with Hepatocellular Carcinoma (HCC). Patients with HKLC stage IIa HCC are eligible for enrollment. In this study, the investigators are looking at the safety, feasibility of the personalized neoantigen-based DC vaccine combined with microwave ablation as well as the T cell immune response to the vaccine.

The purpose of this study is to collect the data on the safety and potential effectiveness of intra-tumor injection of MG7-CART cells under ultrasound guidance in patients with liver metastases expressing MG7 positively.

To investigate the therapy effect and security of oxaliplatin and fluorouracil on with or without concomitant vascular invasion and extrahepatic metastases unresectable advanced primary liver cancer

To evaluate the safety and effectiveness of cell therapy using precision cells Combined With TACE in Advanced Liver Cancer. Eligibility: Individuals greater than or equal to 18 years of age and less than or equal to 65 years of age who have been diagnosed with Advanced Liver Cancer.

This is an open-label, multicenter study designed to assess the safety, tolerability, preliminary efficacy and pharmacokinetics of Metatinib Tromethamine tablet in patients with advanced or metastatic gastric cancer, liver cancer, colorectal cancer,or con squamous NSCLC. Patients receive Metatinib orally 200mg once daily (QD) or 100mg twice daily (BID) until disease progression or unacceptable toxicity occurred. The study will determine whether MET gene mutation, amplification, as well as MET protein overexpression in tumor tissue correlate with treatment efficacy and clinical outcome. The potential PD biomarker for Metatinib will also be explored.

The purpose of this study is to investigate the potential for visualizing radiofrequency-induced (RFA) and microwave-induced (MWA) hepatic thermal ablation lesions using a novel, high resolution, and freehand ultrasound elasticity imaging method in human subjects.

Background: Researchers are trying to learn what causes certain types of cancer to spread to other organs in the body (metastasis). Cancer tumors may produce a very small number of specific cells (cancer stem cells) that cause the tumors to grow in other organs throughout the body. By examining cancer tumor tissue, normal tissue, blood, bone marrow, and other body fluids, researchers may determine whether these samples contain cancer stem cells. Cancer stem cells may provide information on whether the cancer will come back or spread before other routine x-ray studies or lab tests indicate its presence. Objectives: To acquire a collection of solid organ cancer stem cells for future study. To analyze solid organ cancer stem cells from various types of cancer on a genetic level. To determine if solid organ cancer stem cells are present in the blood or bone marrow. Eligibility: Patients 16 years of age and older who have solid organ cancer (cancer in the liver, colon, rectum, anus, pancreas, stomach, breast, skin, muscles, fat, connective tissue, uterus, ovary, cervix, vagina, vulva, or inner lining of the abdomen) or a precancerous growth, and who are scheduled to have a biopsy or surgery to remove the cancer as part of their treatment. Design: This is a prospective trial designed to procure solid organ cancer stem cells before either surgery or biopsy. All patients registered to this trial will undergo surgery to extirpate their cancer in the NCI Prior to surgery or biopsy, 8 tablespoons of blood will be drawn. During the surgery or biopsy, a sample of normal tissue will be removed along with the cancerous or precancerous tissue. If separate consent is given, samples of bone marrow will also be taken. After discharge, patients will return to the clinic for routine visits every month for the first 3 months following surgery, and then about every 3 months for 2 years, and then every 6 months for 3 years. During the visits, patients will have routine blood and imaging studies done, and researchers will take additional blood samples (about 8 tablespoons at each visit) and optional bone marrow samples (4 teaspoons every 6 months) to be used for research.

Study Hypothesis • As well as in animal models as in patients with colorectal cancer resection of the primary tumor resulted in increase in vascular density, metabolism and secondary tumor growth of the distant metastases. These data strongly suggest an inhibitory effect of the primary tumor on the outgrowth of its metastases. In this study we investigate whether pre-operative treatment with the anti-angiogenic agent bevacizumab and/or chemotherapy before resection of the primary colorectal tumor shifts the balance between angiogenic and anti-angiogenic factors in favor of the anti-angiogenic factors and results in reduced growth of the liver metastases. Eligibility Histological proven colorectal cancer without signs of bowel obstruction or bleeding Synchronous liver metastases WHO performance status 0-1 Treatment Arm A: immediate surgery of the primary colorectal tumor, no neoadjuvant therapy Arm B: neoadjuvant treatment with bevacizumab during 7 weeks prior to surgery of the colorectal primary Arm C: neoadjuvant treatment with CAPOX during 7 weeks prior to surgery of the colorectal primary Arm D: neoadjuvant treatment with bevacizumab and CAPOX during 7 weeks prior to surgery of the colorectal primary Primary endpoint Difference in response of liver metastases to resection of the primary tumor between the experimental groups and the control group, as determined by histopathological scoring of vascular density, apoptotic and mitotic index and by measurement of the metabolic activity of liver metastases by FDG-PET and SUV measurements. Secondary endpoints Toxicity of neo-adjuvant treatment Complications of surgery

The objectives for this study include: Testing a unique way of imaging people with colorectal cancer and other cancers that has spread to the liver using magnetic resonance imaging (MRI); Seeing if the MRI process can be used across multiple imaging platforms; Determining whether the results of the imaging can be reproduced; Reviewing how MRI results relate to cancer response to combination therapy and to clinical endpoints.

The primary aim for this trial is to assess whether the RFA aspirator device is safe and of clinical benefit in patients with primary or secondary malignant liver tumours
