Chemotherapy before surgery for high-risk bile duct cancer
This trial tests whether receiving chemotherapy (cisplatin, gemcitabine, and nab-paclitaxel) before surgery can improve outcomes for people with high-risk bile duct or gallbladder cancer. It compares this approach to going straight to surgery.

New PET scan for spotting cancer spread in the abdomen
This trial tests a new type of PET scan (Ga68-FAPI-46) to better see if cancer from the colon, rectum, or ovary has spread to the lining of the belly. If you are already scheduled for surgery to remove these cancer spots, this scan may help your doctors plan a more complete operation.
BrusselsAges 18 years+ - NCT06087861RecruitingPhase 2
Short course radiation before sarcoma surgery
This trial tests a shorter course of radiation (just 5 days) before surgery for soft tissue sarcoma. The goal is to see if a brief, high-dose radiation schedule works as well as or better than the usual longer course—and may be more convenient for you.
Palo Alto, CaliforniaAges 18 years+ - NCT06088134Recruiting
Predicting survival after kidney cancer surgery with CT scans
This study uses a computer model to analyze your CT scans and predict how long you might stay cancer-free after surgery. It aims to help doctors personalize follow-up care for clear cell kidney cancer.
Chongqing, Chongqing MunicipalityAges Any age - NCT06092450Recruiting
Using AI scans to predict bladder cancer treatment results
This trial uses an artificial intelligence model to analyze CT scans taken before bladder removal surgery. The goal is to see if the AI can predict outcomes for patients with muscle-invasive bladder cancer.
Chongqing, Chongqing MunicipalityAges Any age - NCT06136611Recruiting
Pre-surgery Optune for glioblastoma
This trial tests whether wearing a device called Optune (which uses electric fields to slow cancer growth) before surgery helps people with glioblastoma. It is for patients who are fairly active and plan to have standard tumor removal and radiation therapy afterward.
ManchesterAges 35 years+ - NCT06144177RecruitingPhase 4
Induction in the dark for kids having surgery
This trial tests whether having general anesthesia in a dark room (instead of a bright one) helps young children feel calmer. It aims to reduce fear and improve the experience for kids ages 2 to 6.
Charleston, South CarolinaAges 2–6 - NCT06145074RecruitingPhase 2
Testing propranolol before surgery for pancreatic cancer
This trial tests if taking propranolol (a blood pressure medication) before surgery helps treat pancreatic cancer that can be removed. It aims to see if the drug is safe and works well.
CopenhagenAges 18 years+ - NCT06147024Recruiting
Using 3D printed models to plan aneurysm surgery
This study uses a 3D printed model of your artery bulge (aneurysm) to help your surgeon plan the operation before surgery. It may help make the surgery safer and more personalized.
New Taipei CityAges 18–80 - NCT06184724Recruiting
Pre-surgery check for older adults
This trial tests whether a comprehensive geriatric assessment before major surgery helps older adults. It looks at how well clinics can offer this check to patients 80 or older.
Madison, WisconsinAges 18 years+ - NCT06219252Recruiting
Comparing lens power methods during cataract surgery
This study compares two ways to choose the right lens power during cataract surgery: one uses a special measurement during surgery, the other uses standard pre-surgery measurements. The goal is to see which method gives you better vision after surgery.
Mexico City, CuauhtemocAges 40 years+ - NCT06237751Recruiting
Sildenafil before liver surgery
This trial tests if taking sildenafil before liver surgery helps patients. It is for people having a partial liver removal who are in fairly good health.
Chenzhou, HunanAges 18–85 - NCT06239649Recruiting
Nerve block before knee replacement for faster recovery
This trial tests whether a numbing injection (nerve block) around the knee before surgery can help you recover faster and feel less pain after a total knee replacement. It is for people with knee osteoarthritis who are ready for their first knee replacement surgery.
Denizli, PamukkaleAges 40–85 - NCT06266312Recruiting
Lifestyle program before breast cancer surgery
This study tests whether a program of healthy eating, exercise, and stress management before breast cancer surgery is practical and helpful for patients who will receive chemotherapy first. It aims to see if a lifestyle plan can improve your well-being during treatment.
Maastricht, LimburgAges 18 years+ - NCT06304350RecruitingPhase 2
Pembrolizumab plus chemo before surgery for esophageal cancer
This trial tests whether adding the immunotherapy drug pembrolizumab to standard chemotherapy (given before surgery) can help shrink stage II/III esophageal cancer. The goal is to make surgery more likely to remove all cancer and improve outcomes.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT06324565Recruiting
Using D-dimer to find twisted ovaries in teens
This study is checking whether a blood test called D-dimer can help diagnose twisted ovaries (ovarian torsion) in teenage girls. If you have lower belly pain and imaging suggests torsion, this may help doctors catch it sooner.
GrazAges Up to 17 years - NCT06349590RecruitingPhase 1/Phase 2
Diet before colon cancer surgery to reduce recurrence
This trial tests whether a specific diet before colon cancer surgery can change the bacteria in your gut to help prevent the cancer from coming back or spreading. Patients who are eligible will follow the diet for a short time before their operation.
Chicago, IllinoisAges 18 years+ - NCT06379425RecruitingPhase 4
Can pain meds without opioids help you pee sooner after surgery?
This study looks at whether giving a mix of pain medicines (without opioids) before surgery can help you recover faster and avoid needing a catheter after a vaginal repair or sling procedure. It enrolls women having minor gynecologic surgery at the South Shore Surgery Center in New York.

BarcelonaAges 18 years+ - NCT06398613Recruiting
Using PSMA PET scan before prostate cancer surgery
This trial is testing whether a special scan (PSMA PET/CT) before surgery can help doctors decide if you need to remove lymph nodes. It is for men with high-risk prostate cancer who are already planning to have robot-assisted prostate removal.
OsloAges 18 years+ - NCT06421285Recruiting
Exercise before breast cancer surgery to prevent lymphedema
This trial tests whether doing exercise before surgery can help prevent arm swelling (lymphedema) in women being treated for breast cancer. If you are newly diagnosed, facing chemotherapy first, and can exercise safely, this study might be a good fit.
