Using an app to help teens cope with post-surgery pain
This trial tests whether a phone app (iCanCope) can help teens better manage pain after surgery for scoliosis or certain chest conditions (pectus carinatum/excavatum). If you’re having one of these surgeries soon, the app may help with coping and day-to-day comfort after the operation.
Boston, MassachusettsAges 12–18 - NCT05408897Recruiting
Blood test to predict risk after surgery for high-risk GIST
This study uses a “liquid biopsy” blood test to look for leftover cancer signals after surgery. It aims to predict how well treatment will work and how likely the cancer is to come back in people with high-risk GIST.
Beijing, Beijing MunicipalityAges Any age - NCT05424692Recruiting
Test tumor drug sensitivity to guide after-surgery colon cancer care
This study looks at whether testing a small tumor sample can identify which medicines are more likely to work for colorectal cancer after surgery. The results are used to help choose the best “after-surgery” treatment plan, when you have not had chemotherapy before surgery.
Beijing, Beijing MunicipalityAges 18–75 - NCT05430698RecruitingPhase 2
PD-1 antibody after surgery for bile duct cancer
This Phase 2 trial studies whether adding a PD-1 antibody plus gemcitabine/oxaliplatin (GEMOX) after surgery can lower the chance of the cancer coming back in perihilar cholangiocarcinoma. It’s for people who have had surgery with no tumor left at the cut edges, but lymph nodes showed cancer under the microscope.
Guangzhou, GuangdongAges 18–75 - NCT05440149RecruitingPhase 3
Radiation after surgery for certain node-positive breast cancer
This study tests whether giving radiation after breast surgery can improve outcomes for people with breast cancer that has spread to nearby lymph nodes (N1). You may be a candidate if you’ve already had surgery and meet specific details about your lymph nodes and cancer type.
Seoul, Jongro-guAges 19 years+ - NCT05446636Recruiting
Circadian rhythm study for pain after C-section
This study looks at whether your body’s daily rhythm (“circadian rhythm”) is linked to pain after an elective C-section using spinal anesthesia. If you join, you’ll be monitored after surgery to see whether timing or rhythm-related factors change your pain.
Chongqing, Chongqing MunicipalityAges 20–45 - NCT05452694Recruiting
Personalized pain relief after back fusion surgery
This trial tests a personalized plan to manage pain after lumbar (lower back) fusion and decompression surgery. It may help reduce difficult pain while guiding safe use of opioids around the time of surgery.
Pittsburgh, PennsylvaniaAges 18–99 - NCT05491434Recruiting
Study of muscle loss in colon cancer patients
This trial looks at muscle loss (called sarcopenia) in people with colon cancer to test an intervention that may help strength or recovery. If you’re age 70 or older and meet the cancer and health requirements, you may be able to take part.
L'Hospitalet de Llobregat, BarcelonaAges 70 years+ - NCT05494502Recruiting
Nerve block to reduce long-term pain after breast surgery
This trial tests whether a specific pain-numbing nerve block given during mastectomy can reduce chronic (long-lasting) pain after breast cancer surgery. It may help some people use less pain medicine later by lowering nerve-related pain after surgery.
Beijing, Beijing MunicipalityAges 18–85 - NCT05504265RecruitingPhase 2/Phase 3
Pain control methods during minimally invasive esophagus surgery
This study compares different ways to control pain around the time of minimally invasive esophagus surgery. It may help find a method that controls pain better and improves recovery after surgery.
BeijingAges 18–75 - NCT05514405Recruiting
Testing two anesthesia medicines to prevent confusion after surgery
This trial tests whether using remimazolam or propofol during hip or knee replacement surgery can lower the risk of postoperative delirium, a sudden, short-term confusion that can happen after anesthesia. It may help people who are at higher risk of postoperative confusion by finding the safer anesthesia approach.
SeoulAges 65–100 - NCT05525923Recruiting
Personalized pain plan after chest surgery in adults
This trial tests a personalized (tailored) plan to manage pain after thoracic (chest) surgery. It may help improve comfort and recovery by matching pain treatment to your situation after surgery.
Pittsburgh, PennsylvaniaAges 18–99 - NCT05536089Recruiting
Testing blood methylation to predict colorectal cancer relapse
This trial checks a blood test for “ctDNA methylation” to see who may be at higher risk of colorectal cancer returning after surgery. It may help doctors better judge whether adjuvant chemotherapy is working or needed.
Hangzhou, ZhejiangAges 18 years+ - NCT05543785Recruiting
Ketorolac pain block for lower-limb surgery with a tourniquet
This trial looks at whether a ketorolac pain medicine given directly to the leg during surgery can reduce pain after lower-limb orthopedic operations. It may help people who are having one leg operated on with spinal anesthesia and a tourniquet, but it has several safety limits.
Al MansurahAges 19–60 - NCT05545007Recruiting
Pre-op vs post-op focused radiation for large brain metastases
This study compares giving focused, high-dose radiation before surgery versus after surgery for people with large brain metastases. The goal is to see which timing works best to control the tumors and help neurological outcomes.
Brescia, BresciaAges 18 years+ - NCT05549713Recruiting
Upper eyelid surgery to improve early vision quality
This study looks at whether upper blepharoplasty (surgery to remove excess upper eyelid skin) improves how clearly you see soon after surgery. It’s mainly for people whose extra upper eyelid skin blocks part of their vision and causes eye opening trouble and headaches.
OsijekAges 45–90 - NCT05573633Recruiting
Smartwatch test to detect irregular heartbeats after heart surgery
This study checks whether a smartwatch can spot an irregular heartbeat called atrial fibrillation soon after on-pump heart surgery. If the smartwatch works well, it could help clinicians find the problem earlier after surgery.
AmiensAges 18 years+ - NCT05593146RecruitingPhase 2
3D hip reconstruction surgery to prevent dislocation
This trial compares a modified hip implant positioning method to lower the chance of the hip “slipping out of place” (dislocation) after major hip tumor surgery and reconstruction. If you qualify, you may help test whether a small change in implant angle improves stability and function.
Ningbo, ZhejiangAges 16 years+ - NCT05662371Recruiting
Testing pain-monitor guided pain medicine during robot bowel surgery
This study checks whether using a pain-activity monitor during robot-assisted colorectal surgery can help the surgical team choose the right pain medicine. It may improve comfort and reduce the chance of giving too much or too little pain medicine.
