BolognaAges 18 years+ - NCT07551375Recruiting
Fast MRI scan to diagnose gallbladder inflammation
This study tests whether a new type of quick MRI scan can reliably detect acute cholecystitis—sudden inflammation of the gallbladder. If it works well, doctors may be able to diagnose this condition faster and help patients get treatment sooner.

Pre-surgery health check for older adults with liver cancer
This study evaluates a special health assessment designed for patients aged 70 and older who are having surgery to remove liver cancer. The goal is to help doctors better prepare older patients for surgery and improve their outcomes.
Roma, RMAges 70 years+ - NCT07538648RecruitingPhase 1
Imaging Dye for Surgery to Find Solid Tumors
This study tests a new injectable dye (NC527-X) that helps surgeons see tumors better during surgery. The dye glows under special light, making it easier to find and remove cancer tissue completely.
Hangzhou, ZhejiangAges 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+ - NCT07529301Recruiting
Lung Function Tests Before Surgery to Predict Recovery
This study measures your lung function and physical fitness before surgery to see if these tests can predict how quickly you'll recover. The researchers want to understand which patients might have an easier or harder recovery after their operation.
MalatyaAges 18–80 - NCT06755866Recruiting
Predicting chemo-radiation response with improved MRI for esophageal cancer
This trial uses a special MRI technique to see if it can predict how well esophageal cancer responds to chemo-radiotherapy before surgery. It may help doctors choose the best treatment plan for you.
Kunming, YunnanAges 18–80 - NCT07517458Recruiting
Understanding anxiety before cancer surgery in hospitalized patients
This study looks at how anxious cancer patients feel before surgery and tests a new way to measure that anxiety. It's observational—meaning researchers watch and listen rather than give treatments—to help doctors better support patients emotionally before procedures.
Aviano, PordenoneAges 18 years+ - NCT06760221Recruiting
Spotlight on bone cancer: SBRT plus surgery
This trial tests if giving a high dose of focused radiation (SBRT) before surgery can improve outcomes for people with aggressive soft tissue sarcoma in an arm or leg. You may be able to avoid chemotherapy and still have a good result.
Hangzhou, ZhejiangAges 18–80 - NCT07501026RecruitingPhase 2
Testing a new radiation method before sarcoma surgery
This trial tests a new type of radiation called spatially fractionated radiation therapy (SFRT) given before surgery for large soft tissue sarcomas in the arm, leg, or trunk. The goal is to see if it helps shrink the tumor and improve treatment outcomes.
Hangzhou, ZhejiangAges 18–75 - NCT07500519Recruiting
Shock Indexes and Low Blood Pressure After Spinal for Cesarean
This study looks at whether certain simple measurements (called shock indexes) taken before your cesarean delivery can help predict if you might have a drop in blood pressure after you get spinal anesthesia. The goal is to help doctors take better care of moms like you during the surgery.
IstanbulAges 18 years+ - NCT05204108Recruiting
Ultrasound test to check bladder cancer muscle spread
This trial studies a special ultrasound scan with contrast dye to see whether bladder cancer has grown into the muscle layer. It may help doctors plan the best treatment before surgery.
Guangzhou, GuangdongAges 18–75 - NCT07474194RecruitingPhase 4
Cleaning the vagina before c-section to prevent infection
This trial compares two ways to clean the vagina before a planned cesarean section to see which one better prevents infections after surgery. It may help you if you are having a planned c-section.
Banī SuwayfAges 18–40 - NCT04775381RecruitingPhase 3
Vitamin D before thyroid surgery to prevent low calcium
This study tests whether taking vitamin D (cholecalciferol) before a total thyroid removal can reduce the risk of developing low blood calcium afterward. If you’re having your thyroid removed, the results may help prevent symptoms like tingling, cramps, or spasms caused by low calcium.
AuxerreAges 18 years+ - NCT07463352Recruiting
Pre-surgery nutrition for frail seniors with hip fractures
This study tests if giving a special protein drink before surgery helps frail older adults with a broken hip recover better. It might reduce complications after surgery.
DüzceAges 65 years+ - NCT07471464Recruiting

Ultrasound contrast for bladder cancer staging
This trial uses a special ultrasound with contrast dye to get a clearer picture of bladder cancer before any treatment. It aims to improve how doctors determine the stage of the cancer, which helps guide the best treatment plan.
Guangzhou, GuangdongAges 18–75 - NCT06791005RecruitingPhase 3
Timing of carbon nanoparticles injection for thyroid cancer
This trial tests whether the timing of a carbon nanoparticle injection during thyroid cancer surgery improves outcomes. It may help patients who need their whole thyroid removed and have cancer in both lobes or spread to lymph nodes.

Common questions
- Are there clinical trials for preoperative?
- Yes. Clin2 currently lists 376 recruiting preoperative studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a preoperative trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a preoperative trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
