NCT07225114
This is a 4-arm, single-center study involving 40 participants. Ten healthy volunteers will be enrolled for system imaging optimization, and thirty (30) patients with previously identified lesions in the breast, liver, or kidney-based on prior ultrasound or cross-sectional imaging-will be imaged. Recruitment will be conducted such that ten patients are included from each anatomic region. The fourth arm will consist of 10 healthy volunteers who will be imaged to allow optimization of imaging parameters. Optimization is is required again due to the use of a different ultrasound system employing a new imaging technique. Parameters such as frame rate, power, depth of imaging, and linear translation rate will be adjusted during this process. The primary objectives of the study are to assess the sensitivity and specificity of Contrast Enhanced Super-Resolution (CESR) imaging in evaluating known lesions in the breast, liver, and kidney. These results will be compared with pathological findings. The secondary objectives are to compare the sensitivity and specificity of CESR imaging with those of traditional B-mode ultrasound in differentiating malignant from benign lesions in these same organs.

Liver surgeries are high risk surgeries that might result in injuries in kidneys and heart. This study was planned to investigate the frequency of these injuries as well as the risk factors for their devolopment and its effect on patient outcomes.
NCT05169177
This observational study will investigate the properties of image files standardly collected during radiation therapy treatment in a cross-section of liver cancer patients who received stereotactic ablative body radiation therapy (SABR) after trans-catheter arterial chemo emobilisation (TACE). Specifically, it will determine whether the radio-opaque contrast agents in the image files can be detected by tumour-tracking software (KIM).
NCT04518852
Hepatocellular carcinoma (HCC) is the fourth most common cause of cancer-related death that ranks sixth in terms of incident cases, with an overall 5 years survival of 18%. Despite a significant improvement in treatment strategy, the overall survival of HCC remains low due to high recurrence, progressive liver dysfunction and the high fatality of the disease. Surgical resection has been applied in a number of patients; however, surgery has been associated with a high incidence of recurrence (approximately 70% within 5 years). TACE is generally applied on intermediate-stage HCC. However, TACE is not satisfied with improving overall survival. Therefore, there is an urgent need for effective treatment for these patients. At present, the overall objective response rate (ORR) of single or sequential therapy is not satisfied, and the over survival (OS) improvement is not ideal. Therefore, combined therapy maybe the good choice for patients with advanced HCC. This study focuses on the in-operable, BCLC-B/C HCC patients. Through the combination of local therapy (TACE), anti-angiogenic therapy (Sorafenib), and immunotherapy (PD-1 monoclonal antibody), it is expected to change the tumor microenvironment, restore the immune response, strengthen the anti-tumor effect of various treatments, and improve the therapeutic efficacy in patients with BCLC-B/C HCC.
NCT06271109
aimed to discuss the short term surgical outcomes of Anatomical versus Non anatomical laparoscopic Liver resection for Liver tumors.
NCT02571946
The standard treatment of advanced hepatocellular carcinoma (HCC) is sorafenib. Though the agent showed clear survival benefit in two randomized phase III trials, the benefit was modest and response rate was just a few percent. Therefore, other loco-regional modalities, like trans-arterial chemo-embolization (TACE), hepatic arterial infusion chemotherapy (HAIC), and radiotherapy (RT) were continuously tried, especially in locally advanced HCC including portal vein tumor thrombosis (PVTT). With the advancement of conformal RT techniques, RT was actively applied in HCC, especially in PVTT combined HCC. Many researchers reported that there is a relationship between RT dose and tumor response rate. RT dose, however, is frequently limited because the complications (like radiation induced liver disease (RILD), radiation induced gastro-duodenal toxicity, etc.) are also closely related with higher exposed RT dose. Proton beam has characteristic depth-dose distribution contrast to photon, the "Bragg peak". The advantage of this dose distribution could be more highlighted in HCC management, because of the weakness and maintenance importance of liver function itself in HCC patients. In fact, the superior results of proton beam therapy in HCC were constantly reported in several groups as prospectively as well as retrospectively. In those background, the investigators planned the present study to evaluate the efficacy and safety of proton beam therapy in HCC patients combined with PVTT.

NCT05495529
This study aims to analyse retrospectively the feasibility, the safety, and the efficiency, of biliary or digestive protection with room air interposition for thermal ablation of central liver tumors with high iatrogenic risk. Thermal ablation is a mini-invasive and curative treatement of liver tumors. However, it requires to be carefull about surrunding organs, such as digestive structures or central biliary tree, which can be injured if not insulated. The technique of gas interposition to protect adjacent gut is already known and validated with carbonic gas. Nevertheless, resorption of this gas is very fast, making its use tricky to keep a correct insulation during the whole thermal ablation process. Room air interposition is easy to use and can offer a slow resorption speed. Furthermore no datas are available concerning the use of room air whatever the organ protected, and the protection of central biliary tree whatever the gas used.
NCT05261113
Contrast-enhanced intraoperative ultrasound (CE-IOUS) plays an increasingly important role in the surgical therapy planning of primary liver lesions as well as liver metastases. The present study was designed to evaluate the significance of CE-IOUS by specificity and sensitivity and particularly the impact it exerts on the surgical strategy. A secondary aim was assessing the outcome relevance of surgeries influenced by CE-IOUS.
NCT00341484
An NCI goal is to identify every human gene that predisposes people to cancer. Recent studies of HIV-1 indicate that genetic polymorphisms can affect susceptibility to viral infections and that such alleles may be racially restricted, a range of racial and ethnic groups should be included in such studies. We propose to examine genetic determinants of infection with hepatitis B virus (HBV) and hepatitis C virus (HCV) in an ethnically diverse population of injection drug users (IDUs). HBV and HCV are important causes of hepatocellular carcinoma, but little is known about genetic factors that alter susceptibility to these infections. Subjects will be recruited in diverse inner-city neighborhoods as part of the University of California, San Francisco's Urban Health Study. Since 1986, this study has successfully recruited and evaluated IDUs from street-based settings. About half of the participants are African-American, one-third are white, 10% are Latino, and the remainder are Asian or Native American. The mean duration of drug use exceeds 20 years. About 80% of subjects have evidence of HBV infection and a similar prevalence of HCV infections is anticipated. We will enroll about 1500 subjects over a 13 month period. Archived, unlinked serum specimens may be obtained from previous enrollees to increase the sample size, as needed. Highly exposed-uninfected subjects will be ascertained on the basis of the serologic testing for each virus, as well as the duration and frequency of injection drug use. These highly exposed-uninfected subjects will be compared to infected subjects with regard to their frequency of genetic polymorphisms (chemokines, chemokine receptors, human leukocyte antigens, and others), in collaboration with scientists from NCI's Laboratory of Genomic Diversity.

NCT03423056
Patients with gastrointestinal cancer often experience physical deconditioning; this could lead to an increased risk of complications, especially when they require major abdominal surgical procedures. It has been suggested that physical training in the preoperative period could improve their condition, reducing the risk of complications. Although this topic has been investigated, it has not been established yet the best short preoperative aerobic exercise program to enhance the aerobic capacity in patients with gastrointestinal cancer who are going to be to surgical primary management, and consequently, to help patients dealing with the physiological stress involved in a surgical intervention. Main objective: To determine the efficacy and safety of a 4 weeks preoperative exercise program in patients with gastrointestinal cancer scheduled for primary surgery. Materials and methods: This is a Phase II single arm clinical trial that will include patients between 45 and 70 years, with confirmed gastrointestinal cancer (gastric, hepatic, colon or rectal cancer), without electrocardiographic abnormalities, and scheduled for primary surgery in 4 weeks or more since recruitment All the enrolled patients will receive a basal aerobic capacity assessment with the 6-minute walk test. Then, two physical therapist will prescribe them a supervised and individualized aerobic training program in 3 sessions per week during 4 weeks. Each session will last 50 minutes and will increase the heart rate target weekly (from 50% to 70% of the maximum heart rate). The aerobic exercise will be carried on a treadmill or in a stationary bicycle. The post intervention aerobic capacity will be measured at week 3 and 4 with the 6-minute walk test. The main efficacy outcome will be peak oxygen consumption (VO2 peak) and the safety outcomes will be exercise-related adverse events and the program adherence. This protocol was approved by the Instituto Nacional de Cancerología's Ethical Board
