This study is building a huge registry of information and biological samples from adults with or at risk for many types of cancer, as well as healthy volunteers. Researchers will use this resource to study what causes cancer and how to better prevent, detect, and treat it. The re…

This study investigates whether changes in the GBA and PSAP genes are more common in people with multiple myeloma or its precursor condition, MGUS. Researchers will compare the frequency of these gene variants in 300 patients against known population databases. The goal is to bet…

This observational study is collecting genetic and clinical information from 520 people with multiple myeloma to better understand why the disease progresses or comes back. Researchers will analyze tumor DNA and RNA to find patterns linked to treatment response. The goal is to cr…

This study looks at genetic changes in people with early-stage blood cancers or conditions that may lead to cancer. Researchers will analyze blood, bone marrow, or cheek cell samples from up to 10,000 participants to find DNA errors linked to cancer risk and progression. The goal…

This observational study follows 200 people with early blood conditions (MGUS or smoldering myeloma) that sometimes turn into multiple myeloma. Researchers will track age, blood protein levels, bone marrow cells, genes, and bone health to find patterns that predict progression. N…

This study looks at people with early blood disorders (MGUS and smoldering myeloma) who are at risk of developing multiple myeloma, a type of bone marrow cancer. Researchers will use advanced genetic and immune testing on blood and bone marrow samples, along with mouth bacteria a…

This study looks at the quality of life of people with two early blood conditions: MGUS and smoldering myeloma. Researchers will ask 400 participants to fill out short questionnaires about their symptoms and concerns. The goal is to learn what matters most to patients, not to tes…

This study is creating a network of hospitals in Italy to find and treat AL amyloidosis earlier. Researchers will screen people with certain blood conditions (MGUS or smoldering myeloma) using special tests. The goal is to speed up diagnosis, connect patients to the right care, a…

This study is for 1,000 adults with early blood conditions called MGUS or smoldering multiple myeloma. Researchers want to find out why some people's conditions stay stable while others progress to active multiple myeloma. Participants will provide samples and have regular check-…

This study is creating a database of up to 5,000 people in Ohio with plasma cell disorders like multiple myeloma and amyloidosis. Researchers will track treatments, outcomes, and quality of life, while also offering patients access to expert consultations and information about su…

This study investigates how a sugar modification called N-glycosylation affects AL amyloidosis, a rare disease where abnormal proteins build up in organs. Researchers will analyze blood and bone marrow samples from 100 adults with related conditions to better understand the disea…

This study looks at the gut microbiome (the bacteria living in the digestive system) of people with POEMS syndrome, multiple myeloma, MGUS, AL amyloidosis, and healthy household members. Participants provide stool samples at home using a collection kit. The goal is to understand …
