Researchers are collecting blood and tissue samples from people with and without cancer to help evaluate new tests that could detect cancer early. This study aims to create a set of blinded blood samples from both cancer and non-cancer patients to validate these tests, focusing on multiple cancer types and stages. The goal is to improve early cancer detection through laboratory research. Participants complete a questionnaire at the start and provide blood samples at registration and again 12 months later. Those diagnosed with cancer may also have tissue samples collected at these times. The study includes patients with various cancer types and stages, as well as individuals without cancer, with some allowing enrollment before full cancer confirmation under specific conditions. During the study, researchers review the collected samples and questionnaire data to assess test performance by tumor type and clinical stage at diagnosis. Participants are followed for one year after completing the study. Key measurements include the provision of a blinded reference set of cancer versus non-cancer blood samples to support future clinical trials focused on blood-based multi-cancer early detection.

Researchers are evaluating how well serum tumor marker directed disease monitoring STMDDM works compared to usual care in patients with hormone receptor positive, HER2-negative metastatic breast cancer. This trial aims to see if monitoring with serum tumor markers can provide similar overall survival outcomes to the standard approach, which involves regular imaging scans. The study also looks at healthcare costs, patient anxiety, and quality of life related to these monitoring methods. Participants are randomly assigned to one of two groups. In the usual care group, patients receive imaging studies at least every 12 weeks and may have serum tumor marker tests as determined by their doctor. In the STMDDM group, patients have blood tests for specific tumor markers every 4 to 8 weeks, and imaging scans are only done if these markers indicate a possible progression of disease. Both groups continue their monitoring for up to 312 weeks unless the disease progresses. During the study, participants undergo regular assessments including blood tests for tumor markers, imaging scans as needed, and questionnaires about anxiety and quality of life. Researchers track overall survival for up to 312 weeks and compare healthcare costs and patient-reported outcomes for up to 48 to 102 weeks. The study also collects data on how often and by what methods disease monitoring is performed, along with patient and physician preferences related to monitoring.
