Active clinical trials for "Carcinoma"

Background: Fibrolamellar Hepatocellular Carcinoma (FL-HCC) is a rare liver cancer. It usually occurs in young people who have no history of liver disease. Currently the only effective treatment option is surgery that removes the tumor and part of the liver. Researchers want to study the course of the disease to learn more about it. Objective: To collect samples from people with FL-HCC to learn more about the disease and help develop new treatments. Eligibility: People any age with FL-HCC Design: Participants must be enrolled on another NIH protocol. Participants will have at least 1 study visit. They will have: A medical and cancer history A physical exam A review of their symptoms and their ability to do normal activities Tests to produce images of the body. They may have a scan (CT) that uses a small amount of radiation. Or they may have a scan (MRI) that uses a magnetic field. These will examine the chest, abdomen, and pelvis. Blood tests Researchers will study previous tumor samples if they are available. If participants come to NIH for visits on other studies, data will be collected about their disease, tests, treatments, and responses. Tumor tissue will be collected if participants are having it taken for a procedure. All other participants will be contacted to collect this data. They will be contacted once a month for 1 year and 2 times a year after that. Participants will be asked to contact researchers when their health changes. They may come in for more tests.

The purpose of this study is to see if it is possible to establish a relationship between the blood flow and blood volume of liver tumors from CT body perfusion and the radiation dose deposited in the tumors from the radioembolization treatment as measured by PET/CT. The study will do this by: Measuring the blood flow and blood volume of tumors in the imaging data from a CT body perfusion Measuring the radioactivity in the tumors after the radioembolization treatment using PET/CT and then calculating the dose deposited in the tumor Using statistical analysis to assess the relationship between the dose and the perfusion parameters In addition, the research may help develop a method for calculating the dose of radioembolization to be delivered to a liver tumor(s) using blood volume and blood flow data obtained from the CT body perfusion scans.

The purpose of this study is to explore the detection of circulating tumor DNA, soluble immune markers, and the evaluation of peripheral blood mononuclear cells (PBMC).

The purpose of this study is to test the ability of OncAlert™ to screen for cancer and the reappearance of cancer. OncAlert™ was developed by Vigilant Biosciences, a collaborator in this research study. OncAlert™ is an oral rinse which is spit into a cup and sent to a laboratory for analysis. OncAlert™ is considered experimental by the FDA because it is not approved for the screening of cancer.

The aim of this work was to describe SBRT different presentations, to study predictive factors for tumor responses following treatment, and to compare tumor response assessments according to the Response Evaluation Criteria

Rheumatoid arthritis(RA) is a disorder with altered immunologic function and increased risk of developing malignancies, while studies examining the association between hepatocellular carcinoma (HCC) and RA remain lacking. The investigators aimed to investigate the risk of HCC between participants with and without RA.

To evaluate the use of probe-based confocal laser endomicroscopy (pCLE) in human nasopharyngeal mucosa for the differentiation of the nasopharyngeal squamous cell carcinomas.

The purpose of this study is to isolate and measure circulating tumor cells in the blood stream to advance detection of cancer and treatment monitoring. In this study, the investigators will utilize the novel technology for circulating tumor cell detection in order to evaluate their presence in patients with lung cancer.

This study aimed to analyze the outcomes of loco-regional treatment prior Living Donor Liver Transplantation in patients with HCC.

the investigators randomly divide the eligible objects into two groups:1. objects in this group will first receive OE endoscopy observation and subsequent white light imaging(WLI) observation during oropharynx and hypopharynx; 2. objects in this group will first receive WLI observation and subsequent OE observation during oropharynx and hypopharynx. Then, the investigators will compare the detect rate of oropharyngeal and hypopharyngeal superficial squamous cell carcinoma of two groups to find if OE endoscopy can improve the detect rate of oropharyngeal and hypopharyngeal superficial squamous cell carcinoma in esophageal cancer patients.
