Researchers are evaluating how to best recommend chemotherapy for patients with colon cancer after surgery by using the presence or absence of circulating tumor DNA (ctDNA) in the blood. This approach aims to identify microscopic residual tumor cells and may provide better risk prediction for cancer recurrence compared to traditional methods. The trial focuses on patients with Stage IIB, IIC, or III colon cancer who have undergone complete tumor removal. Participants will have their tumor tissue and blood tested centrally using the Signatera assay to determine ctDNA status. Patients without detectable ctDNA may avoid chemotherapy, while those with detectable ctDNA are considered at higher risk and will be randomly assigned to receive different chemotherapy regimens, including mFOLFOX6, CAPOX, or mFOLFIRINOX, given intravenously or orally over periods ranging from 3 to 6 months. The study includes initial screening, treatment, and possible second randomization for patients whose ctDNA status changes during monitoring. During the study, participants will undergo various assessments including blood tests, imaging scans, and performance evaluations to monitor their health and response to therapy. Researchers will track the time to ctDNA positivity and disease-free survival for up to 3 and 5 years, respectively. Safety and treatment effects will be closely observed throughout the study duration, ensuring thorough follow-up and monitoring for all participants.

Researchers are evaluating three different combinations of drugs to treat newly diagnosed multiple myeloma in patients who are considered frail or intermediate-fit and are not eligible for stem cell transplant. This phase III trial focuses on comparing these three-drug induction treatments followed by either double- or single-drug maintenance therapy. The study aims to determine which treatment combination better controls the disease and improves progression-free survival and overall survival. Patients are randomly assigned to one of three treatment groups. Arm 1 (VRd-Lite) receives bortezomib by injection under the skin, lenalidomide by mouth, and dexamethasone by mouth during induction cycles, followed by lenalidomide alone for maintenance. Arm 2 (DRd-R) receives daratumumab and hyaluronidase-fihj injections, lenalidomide, and dexamethasone during induction, followed by lenalidomide alone during maintenance. Arm 3 (DRd-DR) receives the same induction as Arm 2, but maintenance includes both daratumumab and lenalidomide. Induction cycles last up to 9 cycles of 28 days each, and maintenance cycles continue every 28 days if the disease does not progress or toxicity occurs. Participants undergo assessments including tumor evaluations, whole-body imaging, blood tests, and quality-of-life questionnaires. After completing treatment, patients are followed every 3 months for 1 year, every 6 months for 2 years, and then annually for up to 10 years. Researchers will measure progression-free survival, overall survival, response rates, safety, minimal residual disease, and patient-reported health outcomes to understand the treatments' effects and support future care decisions.

Researchers are evaluating how factors like age, gender, other medical conditions, and the type of immunotherapy affect the development of side effects in patients with malignant solid tumors receiving immune checkpoint inhibitor (ICI) therapy. The study aims to develop and validate a risk prediction model for serious immune-related side effects during the first year of ICI treatment. Additional goals include tracking the occurrence of various side effects, quality of life, patient-reported symptoms, and treatment patterns over 12 months, along with studying biological markers that may predict side effect risk. Participants will have tissue samples collected at the start of their cancer treatment and will complete questionnaires at baseline and at weeks 4, 12, 24, and 52. Blood samples may also be collected at multiple times during the study. The study focuses on patients receiving standard-of-care ICI therapy for solid tumors, without combination chemotherapy or other non-ICI treatments. During the study, participants will complete patient-reported outcome forms and health questionnaires to assess side effects and quality of life. Researchers will monitor the occurrence of severe immune-related side effects over 52 weeks and evaluate biological markers from blood and tissue samples. The study also assesses the use of electronic methods for collecting patient data. Total participation includes assessments over approximately one year following treatment start.

This research aims to compare the effects of usual care including regional radiation therapy with no regional radiation therapy in women with low-risk breast cancer. It focuses on patients with node positive breast cancer or T3N0 disease who typically receive endocrine therapy and possibly chemotherapy to prevent cancer recurrence. The study examines whether skipping regional radiotherapy still effectively prevents breast cancer from returning, potentially reducing unnecessary treatment and side effects. Participants will be divided into two groups: one receiving radiotherapy to the breast/chest area and surrounding lymph nodes, and the other receiving no regional radiotherapy. The study evaluates standard treatments, ensuring radiation therapy starts within specific time frames after surgery or chemotherapy. Treatments include breast-conserving surgery or mastectomy, along with endocrine therapy planned for at least five years. During the study, researchers will monitor breast cancer recurrence-free intervals over approximately 9.5 years. Participants will undergo regular assessments to track cancer status, side effects, and overall health. The study includes quality of life questionnaires for some patients and requires ongoing follow-up to document treatment effects, adverse events, and long-term outcomes.
