Warsaw, WarszawaAges 18 years+ - NCT07204795Recruiting
Carbohydrate drink before planned C-section
This study tests if drinking a sugary drink before a planned C-section improves recovery. It may help women feel better after surgery.
ErzurumAges 18 years+ - NCT07557550Recruiting
Relaxation methods before orthopedic surgery: glasses vs. virtual reality
This study tests whether watching relaxing videos through special glasses or a virtual reality headset helps reduce anxiety before orthopedic surgery (like hip or knee replacement). Researchers want to see if these tools work better than no relaxation aid at all.
Amiens, PicardieAges 18 years+ - NCT07384611Recruiting
Predicting difficult airway in children before surgery

AnkaraAges 1 day–12 years - NCT07135817Recruiting
Pre-surgery radiation for spinal tumors
This trial tests whether giving focused radiation before surgery can improve treatment for spinal tumors that have spread from other cancers. It may help people who need surgery for a spinal tumor and have a life expectancy of more than 6 months.
GöttingenAges 18 years+ - NCT07743294Recruiting
Exercise before breast cancer surgery to reduce arm swelling
This trial tests whether doing specific exercises before breast cancer surgery helps reduce arm swelling (lymphedema) after surgery, and improves quality of life and care needs. You would participate in a supervised exercise program before your surgery and then follow up after.
TaipeiAges 20 years+ - NCT05719220Recruiting
Group pelvic floor training before HoLEP surgery
This trial tests whether group pelvic floor exercises done before HoLEP surgery can improve recovery and urinary symptoms in men with an enlarged prostate. It may help some people feel better sooner by strengthening the muscles that control urination.
San Francisco, CaliforniaAges 50–90 - NCT07702487Recruiting
Warming before kidney surgery study
This trial tests if warming the body before kidney surgery can lower lactate levels, which may help recovery. It is for adults scheduled for a planned (not emergency) kidney removal.
Istanbul, SisliAges 18–90 - NCT04699292Recruiting
Registry study for local treatment in soft tissue sarcoma
This registry collects coded information about adults with a specific soft tissue sarcoma (MLS) to better understand how local treatments help. If you qualify, you don’t necessarily receive a new drug in this study—your data is used to improve future care.
AmsterdamAges 18 years+ - NCT05036538Recruiting
Reducing pre-surgery stress to help prevent confusion after heart surgery
This study tests whether a stress-reducing relaxation method before heart surgery can lower the risk of postoperative delirium (sudden confusion) and longer-term thinking problems. It may help you keep clearer thinking in the days and weeks after surgery.
Bad Nauheim, HesseAges 18 years+ - NCT05124236Recruiting
Pre-surgery vs post-surgery focused radiation for brain metastases
This trial compares two ways of giving focused radiation for brain metastases: before surgery or after surgery. It aims to see which timing works better to control tumors while keeping you safe.
InnsbruckAges 18 years+ - NCT05512286Recruiting
Radiation experience after breast surgery with belly flap
This trial looks at how people feel (patient-reported outcomes) and how safe treatment is when radiotherapy is given after a mastectomy with a DIEP belly skin-flap reconstruction. It may help doctors understand which experiences to expect and how to improve care.
Nanning, GuangxiAges 18 years+ - NCT05603078Recruiting
Breast cancer surgery with a tumor-bed boost and standard radiation
This study looks at whether adding extra targeted radiation to the tumor area before breast-conserving surgery, then using modern breast surgery techniques and whole-breast radiation afterward, improves outcomes for early-stage breast cancer. You may be offered a treatment plan designed to better treat the area where the tumor was removed.
Beijing, Beijing MunicipalityAges Up to 55 years - NCT05613478RecruitingPhase 3
Immunotherapy plus targeted medicine with TACE around liver surgery
This Phase 3 trial tests whether combining camrelizumab and apatinib with TACE before/around liver cancer surgery can improve outcomes for people with certain stages of hepatocellular carcinoma (HCC). It may help by strengthening the immune attack on cancer and by blocking blood supply to tumors.
Nanjing, JiangsuAges 18 years+ - NCT05679583RecruitingPhase 2
Pre-surgery focused radiation for resectable pancreatic cancer
This trial studies giving highly targeted radiation before surgery for patients with operable pancreatic cancer. The goal is to shrink or control the cancer before an operation while keeping side effects manageable.
SeoulAges 20 years+ - NCT05851534Recruiting
Pre-surgery risk reduction for pancreatic surgery
This study helps people going for planned pancreatic cancer surgery (with or without chemo beforehand) by focusing on controllable risk factors before the operation. The goal is to improve safety and outcomes after surgery.

Cleveland, OhioAges 18 years+ - NCT06250816Recruiting
Cartoon gowns to reduce anxiety in children before surgery

BursaAges 4–12 - NCT06362616Recruiting
Pre-surgery partial breast radiation for recurrent breast cancer
This trial tests a shorter course of radiation to just part of the breast before surgery for women who have had breast cancer return in the same breast. It's for those who have already had radiation to that breast and have a specific type of cancer (ER+, HER2-).

Common questions
- Are there clinical trials for preoperative?
- Yes. Clin2 currently lists 383 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.
