Active clinical trials for "Liver Neoplasms"

Fluorodeoxyglucose (FDG) positron emission tomography (PET) is now widely used for cancer imaging purpose, notably for preoperative work-up. It aims at visualizing organs metabolism. In case of cancer, metabolism is, classically, increased and some hot spots are visible on PET images. Because of respiratory motion and because the liver is intrinsically FDG avid, some tumours (especially the smallest ones) can be occulted and missed by the clinician. The investigators developed a respiratory-gated PET method in order to reduce the motion issue. This protocol has been validated on lung pathologies. The investigators designed a study to investigate its effect on liver cancer (primary or metastasis) to check if it allows the detection of a higher number of tumour lesions. To that aim, patients who are planned to undergo a surgical intervention on the liver can be proposed to participate this study. After the standard PET acquisition (acquired in free-breathing), an additional 10 minutes respiratory-gated PET acquisition is performed without additional injection. After that, a breath-hold (~10s) CT is performed.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of pyrazoloacridine in treating patients who have unresectable primary or metastatic kidney cancer that has not been previously treated.

The purpose of this study is to design an intervention to increase hepatitis B (HBV) screening among Hmong Americans.

Patients with suspicion of primary or secondary hepatic malignancy in whom a radiological examination is needed in order to decide on the most appropriate treatment.

For patients with recurrent liver cancer after liver transplantation, the median survival time is low and the prognosis is often poor. On the one hand, it is necessary to take into account the weakened effect of postoperative anti-rejection drugs with the use of immune checkpoint inhibitors, and on the other hand, the therapeutic effect of recurrent tumors should be taken into account. Both HAIC (hepatic arterial infusion chemotherapy) and T+A（Bevacizumab+Atezolizumab) have inhibitory effects on tumor, and we consider combining them organically to explore one that not only has a good inhibitory effect on tumor, but also better reduces the risk and degree of rejection. Therefore, in order to determine the feasibility and effectiveness of hepatic arterial infusion chemotherapy combined with Atezolizumab and Bevacizumab in the second-line treatment of patients with recurrent liver cancer after liver transplantation

Major liver resection is associated with substantial intraoperative blood loss. Blood loss in elective liver surgery is a significant factor of perioperative morbidity and mortality, as well as possibly long-term oncologic outcome. The purpose of this study is to use whole blood phlebotomy to decrease the central venous pressure, resulting in a state of relative hypovolemia. It is hypothesized that this intervention will lead to a decrease in blood loss at the time of liver resection.

This study is aimed at assessing whether performing a paravertebral block (a type of regional pain relief) can reduce the pain and anxiety patients experience during radiological procedures on the liver.

Liver cancer including primary hepatocellular carcinoma (HCC) and metastatic liver cancers is one the most common malignancies in the world. Over 10000 new cases per year are diagnosed in Taiwan. Despite the many treatment options, the prognosis of HCC remains dismal. More than 8000 people died of this cancer every year in Taiwan. A majority (70% to 85%) of patients present with advanced or unresectable disease. In contrast, small liver cancers can be cured with an appreciable frequency. Five-year disease-free survival exceeding 50% has been reported for surgical resection, and for the inoperable patients who do not have vascular invasion or extrahepatic spread. Radiofrequency ablation (RFA) is recommended as an alternative curative therapy. However, the main drawback of RFA is its limitation to tumor size and location. The tumors larger than 5 cm in diameter or located adjacent to vessels, could not be ablated completely sometimes. Microwave ablation (MWA) can ablate tumor by higher temperature than RFA, so is supposed not to be diminished by adjacent vessels.

Primary Objective: - To evaluate the efficacy of SECOX regimen by adding oxaliplatin plus capecitabine to sorafenib versus sorafenib alone as palliative treatment for unresectable HCC patients to prolong overall survival (OS) for advanced HCC patients. Secondary Objective: To compare the efficacy of SECOX regimen with Sorafenib alone for progression free survival (PFS) To compare the efficacy of SECOX regimen with Sorafenib alone for response rate (RR) To assess the overall safety profile of SECOX regimen in comparison of Sorafenib alone

The purpose of this study is to determine the efficacy of the Definity (perflutren lipid microsphere Injectable Suspension) ultrasound contrast agent in identifying small tumors (hepatomas & metastases) within the liver. Primary objective: To estimate the increase in conspicuity of small intrahepatic tumors with contrast-enhanced sonography Secondary Objectives: To estimate the effect of tumor type, size, location and depth on the conspicuity of small tumors on contrast-enhanced sonography
