Active clinical trials for "Liver Neoplasms"

This randomized phase II trial studies how well S-Adenosyl-L-Methionine Disulphate P-Toluene-Sulfonate (SAMe) works compared to a placebo in preventing liver cancer in patients with chronic hepatitis C infection. Chemoprevention is the use of certain drugs to keep cancer from forming. The use of SAMe may keep cancer from forming in patients with advanced liver disease

RATIONALE: Celecoxib and erlotinib may stop the growth of tumor cells by blocking some of the enzymes needed for their growth. Celecoxib may also stop the growth of liver cancer by blocking blood flow to the tumor. PURPOSE: This phase I/II trial is studying the side effects and best dose of giving celecoxib together with erlotinib and to see how well they work in treating patients with liver cancer.

This study is for patients that have a type of cancer that arises from the liver, either called hepatocellular carcinoma or hepatoblastoma. The cancer has come back, has not gone away after standard treatment or the patient cannot receive standard treatment. This research study will use special immune system cells called TEGAR T cells, a new experimental treatment. The body has different ways of fighting infection and disease. No single way seems perfect for fighting cancers. This research study combines two different ways of fighting cancer: antibodies and T cells. Antibodies are types of proteins that protect the body from infectious diseases and possibly cancer. T cells, also called T lymphocytes, are special infection-fighting blood cells that can kill other cells, including cells infected with viruses and tumor cells. Both antibodies and T cells have been used to treat patients with cancers. They have shown promise but have not been strong enough to cure most patients. The investigator found from preclinical research that they can put a new gene into T cells that will help them recognize cancer cells and kill them. In our preclinical studies, several genes were made called a chimeric antigen receptor (CAR), from an antibody called GC33 that recognizes glypican-3, a protein found on almost all hepatocellular carcinoma cells and hepatoblastoma cells (GPC3-CAR). In the laboratory the investigators have been doing research into GPC3-CAR cells. They have selected the GPC3-CAR with the strongest ability to recognize hepatocellular carcinoma or hepatoblastoma cells for this study. This is a safety study where the investigator will be testing the ability of GPC3-CAR cells to identify and kill tumor cells in patients. The investigators also tested the effects of adding the molecule interleukin-15 (IL-15) alone or with another molecule called interleukin-21. The investigators found that IL-15 alone or together with IL-21 can help GPC3-CAR T cells last longer which helps them to kill more tumor cells. In this study the investigator will be testing the ability of GPC3-CAR cells to identify and kill tumor cells in patients. This is a study looking at safety and the investigators will therefore be starting with GPC3-CAR T cells alone in a set of patients. The first set of patients will receive GPC3-CAR T cells that also express IL-15. In the second group, the investigators will evaluate GPC3-CAR T cells that express both IL-15 and IL-21. If the investigators are able to safely give GPC3- CAR T cells, they will increase the dose of the combination cells in other patients. The product or dose level of cells that the participant will receive is based on when they are enrolled on the study. The GPC3-CAR T cells are an investigational product not approved by the Food and Drug Administration. The purpose of this study is to find the biggest dose of GPC3-CAR T cells that is safe, to see how long they last in the body, to learn what the side effects are and to see if the GPC3-CAR T cells will help people with GPC3-positive hepatocellular carcinoma or hepatoblastoma.

According to the total population of cancer patients, hepatocellular carcinoma (HCC) and colorectal cancer (CRC), two of gastroenterological cancers are involved in the most acquired five cancers. Colorectal cancer (CRC) is a leading cause of tumor-related morbidity and mortality worldwide, and HCC is one of the top ten cancers in China. Currently, the intervention for gastrointestinal cancers mainly focuses on surgical removal, but patients still have a high risk of recurrence. Thus, the prevention of cancer recurrence is the most crucial topic for the intervention. The pathophysiology of gastroenterological cancers is multifactorial and not yet completely understood. However, immunosuppression is a major contributing factor in tumor cells play a central part in disease progression. It determines the prognosis of patients.

This is a feasibility study requiring only three patients to serve as a proof of concept that gadoxetate disodium (a liver specific contrast agent) can be used to improve images taken just before liver SBRT treatments. The hypothesis of this research is that if gadoxetate disodium improves image quality at the time of treatment, then it can be used for image guided radiotherapy (IGRT). Image guidance is the procedure where the 3D CT image that is used to plan a radiotherapy treatment, is aligned to a 3D image taken just before treatment. The better the alignment, the more accurate the treatment, which is crucial for high dose treatments such as SBRT. This research is important for two main reasons. First, it is much less invasive than the standard of care which involves surgically implanting markers in the liver that can move over time. The benefit to harm ratio for surgery, compared to an injection, is much more dramatic. Furthermore, not all patients are surgical candidates, and therefore in those cases radiation oncologists must prescribed a larger area to treat to ensure that none of the cancerous region is missed. The drawback to this method is the irradiation of more normal tissue than necessary, which although deemed to have a greater benefit than harm, is not ideal. Secondly, this research has strong implications in the field of radiation oncology to move towards patient oriented radiotherapy treatments. If successful, radiation treatment to the liver could be performed in less treatments because of the confidence given to radiation oncologists of the cancer location; knowing exactly the healthy liver regions to avoid.

This is a phase II Randomized comparison clinical trial of activated CIK armed with anti-CD3-MUC1 bispecific antibody for advanced liver cancer. And the aim of this research is to study the clinical efficacy and safety of activated CIK armed with anti-CD3-MUC1 bispecific antibody for liver cancer.

This randomized phase II trial studies how well transarterial chemoembolization (TACE) works compared with TACE plus radiation therapy in treating patients with end stage liver disease, liver tumors, or potential liver transplant candidates. TACE involves reaching up to the blood vessel that feeds the tumor through a catheter placed into the groin vessel. Once the physician has defined the vessel going to the tumor, chemotherapy is infused to the tumor and the vessel is blocked, maintaining the chemotherapy for longer time inside the tumor and stopping the blood flow that feeds the tumor. Stereotactic body radiation therapy (SBRT) is a type of radiation therapy that delivers radiation to the tumor cells but does not harm normal liver cells. It is not yet known whether TACE is more effective with or without SBRT in treating liver tumors.

The purpose of this study is to find out if direct peritoneal resuscitation (DPR) (putting a sugar solution into the abdominal cavity) helps blood flow through vital organs in the body that may suffer from low blood flow due to surgery. We will also try to find out if the DPR will help patients recover faster from liver surgery. Lastly, this study will also try to find if direct peritoneal resuscitation decreases levels of signaling chemicals in the blood called 'cytokines' and a protein called high-mobility group protein 1, which is known to cause tissue damage.

Patients undergo percutaneous radiofrequency ablation of hepatic tumors at Siriraj hospital normally receive only intravenous sedative drugs which sometimes can not provide effective pain control. TPVB is suitable for unilateral operations. And it is increasing popular nowadays because of using ultrasound guided which make it is more reliable and has less side effects especially the severe one such as pneumothorax. To cover all nerve supply liver, we decided to use right TPVB at T5-6, T7-8, and T9-10. The aim of this study is to prove that TPVB can provide an effective pain control for patients undergo liver RFA both at rest and movement (cough). We are going to measure the pain score at recovery room and the effective pain control means patients has mild pain (pain score less </= 3 and do not ask for analgesic drugs).

Patients presenting with multiple innumerable liver metastases will probably never come to resection, however, for all others, including patients with numerous multiple metastases or large metastases, resection should be considered after limited chemotherapy. There is consensus for a backbone chemotherapy consisting of fluoropyrimidine + oxaliplatin. FOLFOX was used in the previous EORTC study and is again recommended. The addition of targeted agents to standard chemotherapy in the perioperative strategy for mCRC might increase the ORR and R0 resectability, without significant increase in toxicity, therefore translating to a better outcome. BOS2 (EORTC 40091) was designed to test this hypothesis in patients with a KRAS wold-type profile. It was decided in parallel to design an open label, randomized, multi-center, 2-arm phase II-III study this time aimed at enrolling KRAS mutated patients. Arm A: (standard) mFOLFOX6 + Surgery Arm B: (experimental) mFOLFOX6 + Aflibercept + Surgery
