Active clinical trials for "Carcinoma"

This clinical trial compares the use of ultrasound for the detection of sentinel lymph nodes (SLNs) to the standard of care (which varies depending on cancer treatment). The ultrasound contrast agent is called Sonazoid and it consists of tiny gas-filled bubbles about the side of red blood cells. Diagnostic procedures, such as ultrasound with Sonazoid, may help identify more SLNs than standard of care in patients with cervical, vaginal, or vulvar cancer.

Background: A radiotracer (or tracer) is a radioactive substance. It is used in Positron Emission Tomography (PET) imaging to help see specific sites in the body. Researchers want to learn if a new tracer can help them better identify hepatocellular cancer (HCC) in people. Objective: To learn if a radiotracer called 18F-DCFPyL can identify sites of HCC better than current standard imaging. Eligibility: Adults aged 18 years and older who may have HCC based on previous standard imaging. Design: Participants will be screened with a medical history, physical exam, and blood tests. They will have a computed tomography (CT) and/or magnetic resonance imaging (MRI) scan. Participants will have a whole-body PET/CT scan. The PET and CT scanners use x-rays to make pictures of the inside of the body. The PET uses a tracer to help make the pictures. Participants will get an intravenous (IV) injection of 18F-DCFPyL 1 hour before the scan. Within two weeks, participants will have a 18F-FDG PET/CT scan. 18F-FDG is a commonly used tracer. They will get 18F-FDG via IV 1 hour before the scan. Participants will have a CT/MRI within 2 months of the first 18F-DCFPyL PET/CT. Participants will have standard treatment for their cancer. During treatment, they will have a tumor biopsy. If the biopsy shows they do not have HCC, they will be removed from the study. For participants who have HCC and their cancer was identified in the 18F-DCFPyL PET/CT, they will have a second 18F-DCFPyL PET/CT and 18F-FDG PET/CT. Participants will have follow-up visits every 3 months for 2 years. Then they will have yearly visits for 3 years....

FAPI is a fibroblast activation protein inhibitor and 68Ga-FAPI-04 is a potential new imaging agent for imaging of carcinoma. 68Ga-FAPI-04 PET/CT is helpful to clarify the benign, malignant and invasive range of the oral carcinoma, locate and qualitatively diagnose the tumor, and make early diagnosis and restaging of recurrent tumor.

This phase II trial studies how well contrast-enhanced ultrasound (CEUS) works for diagnosing patients with renal cell cancer (RCC) that has come back (recurrent) after an ablation. Diagnostic imaging, such as CEUS, may help find and monitor long term renal cell cancer recurrence following cryo or microwave ablation.

Diffusion-weighted magnetic resonance imaging (DWI/MRI) has been described in recent literature as a highly sensitive and specific modality for the detection of peritoneal metastases (PM). It has been demonstrated to be superior to computed tomography (CT) for patients with known peritoneal disease from colorectal and gynaecological malignancies. However, the literature is scarce on the role of DWI/MRI in patients with pancreatic ductal-adenocarcinoma (PDAC). The aim of this study is to prospectively assess the added value of whole-body DWI/MRI (WB-DWI/MRI) to CT for detection of PM in the preoperative staging of patients with high-risk PDAC and evaluate how it correlates with intraoperative findings.

The purpose of this study is to evaluate whether statin could prevent recurrence of hepatocellular carcinoma after curative treatment

The aim of this study is to evaluate the sentinel node policy in early stage endometrial carcinomas at intermediate and high risk of recurrence (by comparing the sentinel node policy to current initial staging protocols).

Most patients undergoing hepatectomy for hepatocellular carcinoma (HCC) suffer from underlying liver disease and are exposed to the risk of postoperative ascites, with subsequent morbidity, liver and renal failure, the need for specific treatments and prolonged hospital stay. Postoperative ascites is favored by an imbalance between portal venous inflow and the diminished hepatic venous outflow. Finding a reversible, non-invasive method for modulating the portal inflow would be of interest: it could be used temporarily during the early postoperative course to prevent acute portal hypertension. Somatostatin, a well-known drug already used in several indications, may limit the risk of postoperative ascites and liver failure by decreasing portal pressure after hepatectomy for HCC in patients with underlying liver disease.

Screening programs for high-grade ovarian carcinoma failed to reduce disease-specific mortality, since they do not offer early enough detection of the disease. Most cases of high grade ovarian cancer develop in the fallopian tubes, hence the universal recommendation for high-risk populations (e.g., BRCA1/2 mutation carriers) is to undergo risk-reducing bilateral salpingo-oophorectomy (RRBSO) around the age of 40. The aims of this trial are: (1) to identify novel early-stage disease biomarkers using liquid biopsies obtained through uterine lavage, and (2) to optimize the technique a of uterine lavage and the processing of the samples for ultimate implementation as a routine diagnostic test for high risk populations.

Study objective: Cohort 1: To quantify the uptake of 68GaNOTA-Anti-HER2 VHH1 in local or distant metastases from breast carcinoma patients and to assess repeatability of the image-based HER2 quantification. The uptake will be correlated to results obtained via biopsy of the same lesion, if available. Cohort 2: To report on uptake of 68GaNOTA-Anti-HER2 VHH1 in different cancer types that might overexpress HER2 Cohort 3: To explore the feasibility and added value of 68GaNOTA-Anti-HER2 VHH1 in the neoadjuvant setting of HER2-expressing breast carcinoma Time schedule: After inclusion, patients will be injected intravenously with 37 - 185 MBq 68GaNOTA-Anti-HER2 VHH1 with a total mass of up to 200 μg NOTA-Anti-HER2 VHH1. Serum and plasma samples will be collected at injection. At 90 min after injection, a total body PET/CT scan will be performed. Patients in cohort 1 will undergo a second PET/CT procedure, identical to the first procedure, within 8 days, with a minimal interval of 18h and maximal interval of 8 days. Patients in cohort 2 can undergo an optional 18F-FDG-PET/CT within 21 days prior to or after 68GaNOTA-Anti-HER2 VHH1. In cohort 1 and 2, based on PET/CT images, up to 2 lesions will be selected for optional image-guided biopsy. Biopsy will be performed max. 28 days after the last PET/CT. Plasma and serum samples will be obtained between 60 and 365 days after first injection for patients in cohort 1 and between 42 and 365 days after first injection for patients in cohort 2. Patients in cohort 3 will undergo 68GaNOTA-Anti-HER2 VHH1 PET/CT prior to the start of neoadjuvant treatment and again after the last cycle of neoadjuvant treatment but prior to surgery. Plasma and serum samples will be obtained before each injection and between 42 and 365 days after the last injection.
