This trial tests whether it's safe to stop immunotherapy once bladder cancer is no longer visible, instead of continuing it for a longer time. It aims to find out if stopping treatment early can reduce side effects while keeping the cancer from coming back.
TianjinAges 18 years+ - NCT03250091Recruiting
Stomach precancer check-up study after scope
This study follows people who have had an upper endoscopy (a camera test through the mouth to look at the stomach) to monitor precancerous stomach changes. It may help doctors learn the best way to watch these spots over time and catch problems early.
RigaAges 18 years+ - NCT02865330Recruiting
Registry study for men on active surveillance for low-risk prostate cancer
This is a registry study that follows men with low-risk prostate cancer who choose active surveillance instead of immediate treatment. It helps doctors understand how safe and effective active surveillance is, including confirming results with repeat biopsies.
ValenciaAges 18–80 - NCT04135664RecruitingPhase 3
Compare surgery vs chemoradiation for early throat cancer
This study compares two ways to treat a type of esophagus cancer: surgical removal (esophagectomy) versus chemoradiation (chemo plus radiation). It is for people with early-stage findings where scans suggest no lymph node spread.
Nanchang, JiangxiAges 18–75 - NCT03491605Recruiting
Follow-up study for people with high EBV virus levels
This study tracks health outcomes over time in people who have a high level of the EBV virus in their blood. It may help researchers understand what happens in chronic (long-lasting) EBV infection and which outcomes to watch for.
Wuhan, HubeiAges Any age - NCT04146077Recruiting
Active monitoring for low-risk prostate cancer
This study tests whether watching low-risk prostate cancer closely (instead of treating right away) is safe. It may help some people avoid early treatments and their side effects while still keeping a close eye on the cancer.
MoscowAges 50–75 - NCT04613570Recruiting
Follow-up endoscopy plan for early stomach changes
This study looks at how often and how intensely to do follow-up stomach camera exams (endoscopy) with small biopsies for people at risk of stomach cancer. It may help personalize your follow-up schedule based on your specific stomach findings.
PortoAges 45 years+ - NCT05326295Recruiting
Breast cancer study using tumor cells in blood
This trial checks whether a blood test that looks at tumor cells can help guide treatment for people with breast cancer. If you join, your care team will follow your responses over time to see if this “phenotype surveillance” approach is useful.
Changsha, HunanAges 18–75 - NCT05363657Recruiting
Registry study for kidney tumor treatment choices
This study is a registry that collects information on how people with localized kidney tumors are treated (either active treatment or watchful waiting). It may help doctors better understand which approaches work best for different patients.
Los Angeles, CaliforniaAges 18 years+ - NCT05396560Recruiting
Stool blood test to decide if follow-up colonoscopy is needed
This trial tests whether a stool blood test can help decide who truly needs a follow-up colonoscopy after prior colon polyps. It may reduce unnecessary colonoscopies while still catching concerning changes early.
Calgary, AlbertaAges 18–74 - NCT05528783Recruiting
Testing FIT-DNA to guide follow-up after colon cancer surgery
This trial checks a stool test called FIT-DNA after colorectal (colon) cancer surgery. It aims to see whether this test can help doctors monitor for recurrence during follow-up and decide how closely to watch.
Guangzhou, GuangdongAges 18–80 - NCT02850588Recruiting
Track outcomes after carotid stent or surgery
This study follows people who need a procedure to treat narrowed carotid arteries, comparing results after either surgery (CEA) or a less invasive procedure (TCAR). It mainly looks at patient safety and outcomes, which can help improve future care.
Chicago, IllinoisAges 18 years+ - NCT05649007Recruiting
Monitoring the Saphir hip stem after new hip replacement
This study watches how a specific hip replacement part (the Saphir stem) performs after primary hip surgery in everyday care. It helps doctors and manufacturers learn about safety and outcomes after the device is already in use.
ToulouseAges 18 years+ - NCT05642338Recruiting
Testing two sampling methods to monitor Barrett’s esophagus
This study compares two ways of taking tissue samples during endoscopy to check how Barrett’s esophagus is changing. The goal is to improve surveillance, especially for finding early precancer or early cancer changes.
Amsterdam, North HollandAges 18 years+ - NCT00901602Recruiting
Study of invasive pneumococcal infections in Lebanon
This study collects laboratory samples from patients with invasive pneumococcal infections to learn about the germ and where it spreads. It may help doctors and public health teams track infection patterns and improve prevention and treatment planning.
BeirutAges 1 day+ - NCT05742490Recruiting
Track infections in newborns to improve care
This study collects information about newborns in participating hospital units who have an infection confirmed by a lab test. The goal is to better understand infection patterns so care for newborns can improve.
LondonAges 1 minute–1 year - NCT04462458Recruiting
Study tracking outcomes after ACL reconstruction surgery
This is a study that follows adults who had an ACL tear treated with ACL reconstruction. It helps understand how the surgical device/material performs in real-world care.
InnsbruckAges 18 years+ - NCT05253872Recruiting
Danish study to track early melanoma after surgery
This study tests a new way to monitor people after surgery for early-stage melanoma. If you qualify, it may help your doctors watch for changes sooner or more accurately during follow-up.
CopenhagenAges 18 years+ - NCT05929365Recruiting
Test genetic marker tracking to find returning colon polyps
This study looks at stool or tissue DNA changes (called mutation analysis) plus colonoscopy findings to detect whether colon polyps come back. It may help catch recurrent colorectal lesions earlier during surveillance after a large polyp was removed.
PragueAges 18–75 - NCT04549688Recruiting
Active surveillance with focused ultrasound for prostate cancer
This trial studies whether a high-intensity focused ultrasound treatment can help people with localized prostate cancer while still avoiding traditional full-dose treatment for some patients. It may be an option for certain intermediate-risk cases where the cancer is confined to the prostate.
Tønsberg, VestfoldAges 18–80 - NCT07855679Recruiting
Pulmonary embolism tracking from emergency care to long-term follow-up
This study follows people who have had a pulmonary embolism (a blood clot in the lungs) to understand their health over time and improve future care. It does not test a new treatment but collects information to learn more about recovery.
