Researchers are comparing the rates of surgical and minimally invasive interventions, as well as any harms, in Medicare beneficiaries treated with the MILD procedure versus those treated with interspinous process decompression IPD for lumbar spinal stenosis with neurogenic claudication. This observational study uses Medicare claims data to follow patients for 24 months after their initial procedure starting from January 1, 2017. The purpose is to evaluate outcomes between these two types of procedures without requiring prior patient enrollment or consent. The study includes two groups patients who received MILD, which is a percutaneous image-guided lumbar decompression performed under fluoroscopic guidance through a dorsal approach to the spine, and patients who received IPD, a different device-based decompression procedure. Data on reoperations and complications will be collected for both groups over a 24-month follow-up period using Medicare claims. Enrollment continues until the sponsor decides to stop. Participants involvement is passive as the study uses existing Medicare claims data. Researchers will monitor rates of harms related to the initial procedure and subsequent surgical or minimally invasive interventions over two years. No direct patient visits or interventions are conducted, and the study is exempt from institutional review board oversight. The total study duration extends to December 2026, covering cases treated since early 2017.

Researchers are evaluating whether adding stereotactic body radiation therapy SBRT to the usual treatment improves outcomes for patients with locally advanced, inoperable non-small cell lung cancer NSCLC that has spread to nearby tissues or lymph nodes. This phase III trial compares the effect of SBRT combined with conventional image guided radiation therapy IGRT, chemotherapy, and immunotherapy or targeted therapy against the usual treatment alone. The study aims to assess overall survival, progression-free survival, tumor response, lung function, quality of life, and treatment-related side effects. Participants are randomly assigned to one of two groups. In the first group, patients receive conventional IGRT and chemotherapy with drugs such as paclitaxel, carboplatin, pemetrexed, cisplatin, or etoposide during radiation, followed by immunotherapy with durvalumab or targeted therapy with osimertinib. The second group receives SBRT combined with conventional IGRT and similar chemotherapy, followed by the same immunotherapy or targeted therapy options. Both groups undergo CT andor PETCT scans during follow-up. Chemotherapy schedules vary by drug, including weekly or every 21-day dosing during radiotherapy, with consolidation treatments lasting up to one year. Throughout the study, participants undergo assessments including lung function tests FEV1 and DLCO, quality of life questionnaires, imaging scans, and monitoring for side effects using standard criteria. Follow-up visits occur every three months for the first year, every six months during years two and three, and annually thereafter, continuing for the duration of the study. Biospecimens and advanced imaging data are collected for exploratory analyses, including development of machine learning tools for radiation planning. Overall survival and progression-free survival are the primary outcomes measured up to eight years after randomization.
