MoscowAges 45–74 - NCT05912257Recruiting
Nutrition program before and after surgery to protect function
This study tests whether an “optimizing nutrition” plan before and after cancer surgery can help older adults maintain physical strength and daily functioning. You may be randomly assigned to the nutrition program or another study group, and you’ll be asked about diet and physical function.
Durham, North CarolinaAges 55 years+ - NCT06038227Recruiting
Robotic vs. VATS surgery for early lung cancer
This study compares two types of minimally invasive surgery—robotic-assisted (da Vinci) and VATS—for people with early-stage non-small cell lung cancer. The goal is to see which approach might work better and help patients recover faster.
CopenhagenAges 18 years+ - NCT04888975Recruiting
Device study for one-arm swelling after lymph surgery
This study tests a medical device (Dayspring Technology) to reduce swelling in the arm caused by breast cancer treatment and lymph surgery. You may be eligible if you have one-sided arm swelling after lymphatic surgery and meet safety checks for the device.
Palo Alto, CaliforniaAges 18 years+ - NCT06338332Recruiting
Stent before surgery for right-sided colon blockage from cancer
This trial tests whether placing a stent first to relieve a blockage in the right side of the colon improves outcomes before surgery for colon cancer. It aims to help patients who come to the hospital with a blocked colon due to cancer.
Breda, North BrabantAges 18 years+ - NCT07802197Recruiting
Radiation before surgery for advanced rectal cancer
This trial compares giving radiation therapy before surgery versus going straight to surgery for people with advanced rectal cancer that has not spread to other parts of the body. It aims to see which approach may be better for controlling the cancer.
IstanbulAges 18 years+ - NCT06764134Recruiting
Testing a new stapler to prevent pancreatic leaks after surgery
This trial tests a new type of stapler (AEON) used during surgery to remove the left part of the pancreas. The goal is to see if it helps reduce the risk of a leak from the pancreas after surgery.
Heidelberg, Baden-WurttembergAges 18 years+ - NCT06888063RecruitingPhase 2
Chemo pump into the liver for bile duct cancer that can be surgically removed
This trial tests whether giving extra chemotherapy directly to the liver through a small pump (called HAIP) before or after surgery can improve outcomes for patients with bile duct cancer inside the liver. It is for patients whose cancer is considered removable by surgery.
Rotterdam, South HollandAges 18 years+ - NCT06796348Recruiting
Needle treatment vs surgery for small thyroid cancers
This study compares a non-surgical procedure (radiofrequency ablation) with partial thyroid removal (hemithyroidectomy) for treating small thyroid cancers. It aims to find out if the needle-based treatment is as effective as surgery, with fewer side effects.
AarhusAges 30 years+ - NCT05072314RecruitingPhase 3
Lidocaine drip after breast surgery to improve long-term pain
This Phase 3 study tests whether a long-running lidocaine (a numbing medicine) drip given around the time of breast surgery can improve long-term post-surgery pain and recovery. It may help people who have pain after mastectomy or breast-conserving surgery.
Kingswood, New South WalesAges 18 years+ - NCT01762813Recruiting
Study of blood/tissue markers in colorectal cancer surgery patients
This study looks at colorectal cancer patients who are planning curative surgery and collects related outcomes and lab “biomarker” information to better understand the disease. Your participation may help researchers connect test results to treatment results over time.
StavangerAges 18 years+ - NCT03541928RecruitingPhase 2
Gene therapy with standard treatment for high-risk prostate cancer
This trial combines gene therapy with hormone therapy, radiation, and possibly surgery to treat high-risk prostate cancer. It aims to improve outcomes by adding gene therapy to standard treatments and will require additional biopsies.
