Researchers are studying premenopausal women with early-stage breast cancer that is estrogen receptor-positive and HER2-negative, focusing on tumors with specific gene recurrence scores. The trial aims to find out if adding chemotherapy to ovarian function suppression plus endocrine therapy improves invasive breast cancer-free survival compared to ovarian function suppression plus endocrine therapy alone. This Phase III trial addresses the need for better treatments in younger women, given their higher risk and past conflicting study results on ovarian suppression and chemotherapy. Participants are randomly assigned to one of two groups one receiving ovarian function suppression combined with an aromatase inhibitor for five years, and the other receiving adjuvant chemotherapy followed by the same ovarian function suppression and aromatase inhibitor regimen. Choices for the aromatase inhibitor and gonadotropin releasing hormone agonist are made by the investigator, with options including drugs such as goserelin, leuprolide, or triptorelin. Endocrine treatment beyond five years is at the investigators discretion, and bilateral oophorectomy may be used instead of ovarian suppression if preferred. During the study, participants are monitored over 11 years from randomization, with measurements including invasive breast cancer-free survival as the primary outcome. Secondary outcomes include disease-free survival, overall survival, recurrence intervals, menopausal symptoms, and pain during aromatase inhibitor therapy. Safety and treatment effects are assessed through regular evaluations, and participants continue to be followed long term to understand the impact of treatments on their breast cancer outcomes.

Researchers are studying colorectal cancer CRC in participants aged 45 to 70 who have 1 to 2 non-advanced adenomas, which are small colon polyps without high-risk features. The trial compares two surveillance colonoscopy schedules one group receives colonoscopy at 5 and 10 years after polyp detection, while the other group has colonoscopy only at 10 years. This study aims to provide randomized data to guide optimal timing for follow-up colonoscopies to help reduce CRC incidence and improve clinical practices. Participants are randomly assigned to one of two groups the first group undergoes surveillance colonoscopy at both 5 and 10 years following their qualifying colonoscopy, and the second group undergoes colonoscopy at 10 years only. All colonoscopies, including any unscheduled ones, follow current quality guidelines and institutional preparation standards. The qualifying colonoscopy must have been complete and performed within 4 years before randomization, with all polyps fully removed. During the study, participants will undergo colonoscopies according to their assigned schedules. Researchers will monitor the incidence of colorectal cancer over 10 years as the primary outcome. Participants must be able to understand English or Spanish to complete required procedures. The study may last up to several decades, with ongoing monitoring to assess long-term cancer incidence and the effectiveness of different surveillance intervals.

Researchers are evaluating a master screening protocol called Lung-MAP for patients with previously treated non-small cell lung cancer. This phase IIIII trial aims to develop a genomic screening method for large cancer populations and assign participants to appropriate sub-studies based on specific cancer biomarkers. The goal is to compare new targeted therapies designed to block cancer growth or spread with standard care, including sub-studies for patients not eligible for biomarker-driven treatments. The study involves screening patient specimens to determine eligibility for various biomarker-driven or non-matched sub-studies within the Lung-MAP umbrella protocol. This is a screening study without direct interventions instead, patients are assigned to different treatment sub-studies, each operating independently. The protocol also includes an optional ancillary study evaluating attitudes about the return of somatic mutation findings suggestive of germline mutations. Participants provide tumor tissue for biomarker testing, including molecular profiling and PD-L1 analysis, and may submit fresh biopsies and blood samples for circulating tumor DNA testing. Researchers will monitor screening success rates up to three years and collect patient and physician feedback on genetic findings. Participation involves signing informed consent, providing smoking history, and possibly completing surveys. The study duration and assessments vary depending on sub-study assignment and patient progression.

Researchers are evaluating the addition of pembrolizumab immunotherapy to standard chemotherapy for patients with stage IIA, IIB, IIIA, or IIIB non-small cell lung cancer NSCLC that has been completely removed by surgery. This phase III trial aims to compare disease-free survival and overall survival among different treatment approaches, including chemotherapy alone, chemotherapy followed by pembrolizumab, and chemotherapy combined with pembrolizumab. The study also assesses quality of life and adverse event rates in these patient groups. Participants are randomly assigned to one of three groups. One group receives only chemotherapy with observation afterward. The other two groups receive chemotherapy followed by pembrolizumab or chemotherapy combined with pembrolizumab. Chemotherapy involves one of four platinum doublet regimens administered every 21 days for four cycles, depending on the physicians choice. Pembrolizumab is given intravenously over 25-40 minutes, either after chemotherapy or alongside it, repeated every 21 days or every 6 weeks for multiple cycles. Patients also undergo heart ultrasound, MRI, CT scans, and blood sample collections as part of the study. During the trial, participants have regular medical assessments including imaging and blood tests to monitor their health. Follow-up visits occur 6 weeks after treatment, then every 3 months for 2 years, every 6 months for years 2-4, and annually up to 10 years from randomization. Researchers measure disease-free survival as the main outcome, tracking the time until cancer recurrence or death. They also evaluate overall survival, side effects, drug tolerability, and patient-reported quality of life over time.
