This pilot study tests whether it is safe and feasible to skip surgery in patients with stage II-III non-small cell lung cancer who have a complete response to chemotherapy and immunotherapy. Fourteen participants will be randomly assigned to either observation or standard surger…

This study looks at stroke patients who have small clots remaining in smaller brain arteries after the main clot has been removed. Half will get an extra procedure to remove those leftover clots, while the other half will receive standard care without extra intervention. The goal…

This phase 2 trial tests whether adding precise external beam radiation to standard radioligand therapy can better control metastatic prostate cancer that no longer responds to hormone therapy. About 120 participants will receive either standard treatment alone or combined with t…

This study tests whether daily adaptive radiotherapy (ART) can safely deliver shorter, more intense radiation treatments for prostate, endometrial, cervical, and rectal cancers. About 264 participants will be randomly assigned to standard radiation or ART, which uses daily imagin…

This study tests whether adding a heat treatment (thermal ablation) to the standard procedure for removing large colon polyps can lower the chance they grow back. About 752 adults will be randomly assigned to receive either standard removal alone or standard removal plus burning …

This study tests whether wearing a special cast for one week can improve thick, itchy burn scars. Researchers will compare treated scars to untreated ones in 38 adult burn survivors. They will measure changes in scar thickness, redness, moisture, itching, and pain.

This study will compare two surgical techniques for trigger finger, a condition where a finger gets stuck in a bent position. One method makes a small cut in the tendon sheath, while the other removes a piece of it. Researchers want to see which approach leads to fewer recurrence…

This early-stage trial tests a new robotic surgical method for esophageal cancer that avoids cuts between the ribs, which may cause less chest pain and faster recovery. About 31 adults with stage I to III esophageal cancer will be randomly assigned to either the new approach or s…

This study tests whether a structured recovery program helps people who have heart surgery with a heart-lung machine recover faster. The program includes steps before, during, and after surgery to reduce pain, lower opioid use, and shorten hospital stays. About 92 adults having t…

About 1 in 10 people who have noncardiac surgery experience a heart injury, which raises their risk of death within 30 days. This pilot study will test whether routinely referring these patients to a heart specialist (internist or cardiologist) helps them get the right medication…

This study will give 80 healthy adults who use cannabis occasionally different low doses of inhaled CBD (5 to 100 mg) or a placebo to see if they feel a pleasant effect. Each person will try all doses in a random order, and researchers will also explore if current tools miss any …

This study will compare two surgical techniques for treating pain after a finger amputation: reconnecting the nerve (microanastomosis) versus cutting and burying it (traction neurectomy). Researchers will track pain levels and hand function in 50 adults over six months. The goal …
