Researchers are evaluating whether breast conservation surgery combined with endocrine therapy can achieve a similar rate of invasive or non-invasive ipsilateral breast tumor recurrence (IBTR) compared to breast conservation surgery followed by breast radiation and endocrine therapy in patients with Stage I, hormone sensitive, HER2-negative breast cancer with an Oncotype recurrence score of 18 or less. This Phase III trial builds on the established role of radiation after lumpectomy, aiming to identify if radiation can be safely omitted in certain low-risk patients to reduce treatment burden and side effects. Participants receive either breast radiation plus endocrine therapy or endocrine therapy alone. Radiation therapy involves external beam radiation to the whole breast with or without a boost, partial breast irradiation, or accelerated partial breast irradiation, starting within 12 weeks after the last breast surgery. Endocrine therapy is given for a minimum of 5 years, with the specific drug choice and schedule determined by the treating physician. Endocrine therapy may begin before, during, or after radiation therapy, depending on the treatment group. Throughout the study, participants undergo regular assessments including imaging such as mammograms or MRI within six months before enrollment, and clinical evaluations to monitor tumor recurrence. The main outcome measured is the time to invasive or non-invasive ipsilateral breast tumor recurrence over five years. Safety, adherence to therapy, and recovery from surgery are also monitored. The total participation period includes at least five years to evaluate long-term recurrence rates.

Researchers are evaluating surgical and minimally invasive treatments for lumbar spinal stenosis (LSS) by comparing Medicare patients who received the MILD procedure against those who had interspinous process decompression (IPD). The study focuses on outcomes such as the rate of harms related to the initial procedure and the frequency of additional surgical or minimally invasive interventions within 24 months after treatment. Enrollment includes patients treated from January 1, 2017, onward, with continuation until the sponsor decides to stop. The MILD procedure involves percutaneous image-guided lumbar decompression, performed under fluoroscopy through a dorsal approach to partially remove tissue and bone at the affected spinal level. The control group receives the IPD procedure for LSS. Both groups are monitored for a 24-month period post-index procedure using Medicare claims data to track reoperations and any harms. Participants contribute data through Medicare claims without needing prior enrollment or consent, as the study is exempt from IRB oversight. Researchers collect and analyze information on procedure-related harms and subsequent interventions over two years. This approach allows evaluation of long-term safety and effectiveness outcomes for patients treated with either MILD or IPD.

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.
