Researchers are evaluating a treatment approach for early-stage hormone-sensitive, HER-2 negative breast cancer with an Oncotype recurrence score of 18 or less. This Phase III trial compares breast conservation surgery with endocrine therapy alone against breast conservation surgery with both radiation and endocrine therapy. The goal is to see if skipping radiation after lumpectomy is not worse in preventing cancer recurrence in the same breast. Participants will be randomly assigned to one of two groups. One group will receive radiation therapy to the breast plus at least five years of endocrine therapy with drugs such as Tamoxifen, Anastrozole, Letrozole, or Exemestane. The other group will receive endocrine therapy only for at least five years without radiation. Radiation must start within 12 weeks of surgery if assigned. Endocrine therapy dosing and schedule are determined by the treating doctor. During the study, participants will have regular follow-ups up to five years to monitor cancer recurrence in the breast and elsewhere, survival, and breast preservation. Assessments will include clinical exams, imaging like mammograms or MRI, and pathology reviews. The main outcome is time to invasive or noninvasive breast tumor recurrence within five years. Some measures will continue through an average of 15 years, including breast conservation rates. Safety and overall health will be monitored throughout and after treatment.

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.

This trial studies patients with extensive stage small cell lung cancer that has spread outside the lung. It compares the effects of adding radiation therapy to the usual maintenance treatment with atezolizumab versus using atezolizumab alone. Researchers aim to see if combining radiation with immunotherapy can extend the time before the cancer grows or spreads, and improve overall survival. The study is a phase IIIII randomized trial sponsored by the National Cancer Institute. Participants are randomly assigned to one of two groups. One group receives atezolizumab intravenously every 21 days. The other group receives the same atezolizumab treatment plus radiation therapy once daily on days 1 through 5 during the first five weeks. Both groups undergo imaging scans including PETCT, CT, and MRI, as well as blood and tissue collections during the trial. Throughout the study, participants are monitored closely with scans and lab tests. After treatment ends, follow-up visits occur every 3 months for 2 years, then every 6 months for 3 years, and annually thereafter. Researchers measure progression-free survival and overall survival up to 6 years, along with side effects and how tumor characteristics may affect outcomes. The trial evaluates the benefits and risks of combining radiation with atezolizumab for this cancer.

Researchers are investigating treatments for men with prostate cancer that has returned after surgery, focusing on those who experience a rise in prostate-specific antigen PSA levels, indicating biochemical recurrence. The study examines whether adding enhanced systemic therapy apalutamide combined with abiraterone and prednisone to standard care, which includes prostate radiation therapy and short-term androgen deprivation, improves outcomes. Additionally, for patients whose cancer has spread beyond the pelvis as detected by PET imaging, the study evaluates the benefit of adding metastasis-directed radiation therapy. Participants undergo baseline PETCT or PETMR scans to determine the extent of cancer spread. Based on these results, they are randomized into one of four treatment arms standard radiation with androgen deprivation, enhanced therapy including apalutamide, or enhanced therapy plus targeted radiation for metastatic disease. Treatments involve various forms of radiation therapy, androgen deprivation drugs, and oral apalutamide, administered over six months in the absence of disease progression or unacceptable side effects. Some patients may receive repeat PET scans to assess treatment response. During the study, participants have scheduled assessments including imaging, blood tests measuring PSA levels, and quality-of-life questionnaires over up to ten years. Follow-up visits occur every three months for the first two years, then less frequently up to ten years. Researchers monitor progression-free survival, overall survival, event-free survival, PSA progression, adverse events, and quality of life measures including cognitive function and fatigue. This long-term monitoring aims to determine the effectiveness of the added therapies compared to standard treatment alone.
