Prospective observational study to validate the performance characteristics and clinical utility of Cxbladder tests in a Veterans Affairs cohort.

This research trial studies how well biospecimen collection works in identifying genetic changes in patients with breast, prostate, colorectal, liver, or kidney cancer or multiple myeloma undergoing surgery. Studying samples collected during surgery may add to the understanding of cancer by looking for the genetic changes that cause early cancer onset in people of certain racial and ethnic groups.

This is a case-control study designed to evaluate the role of anatomic site, gender and race in human papillomavirus-associated head and neck squamous cell cancers (HNSCC). We will explore the role of HPV, tobacco, alcohol and drug use, in HNSCC by tumor site with particular emphasis on the sinonasal cavity as well as differences in risk factors for HPV-positive HNSCC by gender and race.

This early phase I trial tests the use of a radioactive tracer (a drug that is visible during an imaging test) known as 18F-FMAU, for imaging with positron emission tomography/computed tomography (PET/CT) in patients with brain cancer or cancer that has spread to the brain (brain metastases). A PET/CT scan is an imaging test that uses a small amount of radioactive tracer (given through the vein) to take detailed pictures of areas inside the body where the tracer is taken up. 18F-FMAU may also help find the cancer and how far the disease has spread. Magnetic resonance imaging (MRI) is a type of imaging test used to diagnose brain tumors. 18F-FMAU PET/CT in addition to MRI may make the finding and diagnosing of brain tumor easier.

This trial studies the biospecimen and medical data collection in creating a research tissue registry in patients with inflammatory or invasive breast cancer. Collecting medical data and storing samples of blood, tissue, and stool from patients with inflammatory breast cancer to study in the laboratory may help doctors find better ways to treat and study inflammatory breast cancer in the future.

This study evaluates whether adding a polygenic risk score evaluation to standard breast cancer risk assessment tools helps African American and Hispanic women make more informed decisions about accepting additional breast cancer screening and prevention strategies. Traditional breast cancer risk assessments rely mostly on the presence of standard clinical risk factors including family history, reproductive history, and mammographic breast density. This information can be combined with validated risk estimation models to provide a measure of a patient's 10 year and lifetime risk for breast cancer. A polygenic risk score helps to estimate breast cancer risk in a more individualized way by evaluating a patient's genetics. Adding a polygenic risk score evaluation to traditional screening techniques may help minority women make more informed decisions about screening and prevention strategies for breast cancer.

Mohs micro-graphic surgery (Mohs) is a tissue-sparing, surgical treatment for different types of skin cancer (e.g. basal cell carcinoma, squamous cell carcinoma, lentigo maligna (melanoma). It is a procedure performed with frozen sections. Slow Mohs, a variant of micro-graphic surgery, is performed by formalin fixation and paraffin-embedded sections. Both in Mohs and Slow Mohs tumor margins are assessed to achieve complete removal. This study aims to investigate the clinical presentation and outcomes (i.e. complications and recurrence rates) in patients treated with Mohs or Slow Mohs in the dermatology department of the Maastricht University Medical Center+ in Maastricht, the Netherlands.

Immune checkpoint inhibitors (ICIs) have revolutionized the treatment of advanced HCC. The combination of the ICI and other treatment regimens (Anti-VEGF, locoregional therapies et al) produced superior results in patients with advanced-stage HCC compared to those treated with traditional therapeutic regimens. Liver transplantation (LT) offers excellent long-term outcomes for certain patients with HCC. However, the immune-stimulating property of ICIs may lead to rejection and even graft loss, damping their use in treating HCC before liver transplantation. Therefore, it is worthwhile to explore the relationship between exposure to ICIs before LT and the incidence of graft rejection and rejection-related death or graft loss after LT.

A prospective cohort of papillary thyroid carcinoma(PTC), patients who received thermal ablation in our hospital since February 2023 was established as the study object. Preoperative and postoperative demographic data, ultrasonography, other relevant laboratory tests, and thyroid disease-related scales such as fatigue, depression, and stress were collected. The influencing factors of PTC recurrence were analyzed.
