This study tests whether an automatic reminder system can help more people with stomach precancerous changes get the follow-up checks they need after an upper endoscopy. The goal is to see if the system improves how often patients return for surveillance.
Quanzhou, FujianAges 18 years+ - NCT04455932Recruiting
Test shorter MRI versus ultrasound for liver cancer screening
This study compares a shorter, non-contrast MRI and ultrasound to monitor for liver cancer in people with cirrhosis whose ultrasound images aren’t clear enough. It aims to see which method works better and may help you get safer, more reliable follow-up.
Camperdown, New South WalesAges 20–85 - NCT07023432RecruitingPhase 2
Belzutifan vs. watchful waiting for slow-growing kidney cancer
This trial compares two approaches for people with slow-growing, metastatic clear cell kidney cancer: taking a daily pill (belzutifan) or monitoring the cancer closely without treatment. The goal is to see if starting treatment early can help control the cancer longer than waiting.
Houston, TexasAges 18 years+ - NCT06803147Recruiting
Stopping Surveillance for Low-Risk Barrett's Esophagus
This study is testing whether it's safe to stop regular surveillance endoscopies for people with low-risk Barrett's esophagus. If you have a short Barrett's segment without any dysplasia, you may be able to avoid future procedures.
AmsterdamAges Any age - NCT02971085Recruiting
Registry for prostate cancer on active surveillance
This study follows men with low-risk prostate cancer who choose active surveillance (watching closely instead of immediate treatment). It aims to better track which monitoring results stay reassuring over time, and when treatment might be needed.
SeoulAges 40–80 - NCT03804320Recruiting
Watching small kidney tumors over time instead of treating
This study follows people with small, solid kidney tumors using active surveillance (regular monitoring) rather than immediate surgery or treatment. It may help you understand whether careful watching is a safe option for certain early kidney tumors.
MilanAges 50 years+ - NCT04829708RecruitingPhase 3
Preventing brain spread in limited-stage small cell lung cancer
This trial compares two ways to manage limited-stage small cell lung cancer that has improved after initial chemotherapy and radiation. Participants will either get preventive brain radiation or have regular brain MRI scans instead, to see which approach is safer and works better.
Jinan, ShandongAges 18–75 - NCT06343077RecruitingPhase 2
Hiltonol injection for prostate cancer on active surveillance
This trial tests a drug called Hiltonol (Poly-ICLC) given directly into the prostate tumor along with an injection under the skin. It is for men with low-risk prostate cancer who are on active surveillance, to see if the drug can slow or stop the cancer from growing.
New York, New YorkAges 18 years+ - NCT06336187Recruiting
Active monitoring for small kidney tumors
This study tests whether closely monitoring small kidney tumors (less than 4 cm) with regular imaging is a safe and effective option for people who cannot or choose not to have immediate treatment. It involves a biopsy at the start to confirm the tumor type.
NovaraAges 18 years+ - NCT07749924Recruiting
Watchful waiting vs. bladder chemotherapy for intermediate-risk bladder cancer
This study compares two approaches for people with intermediate-risk bladder cancer whose urine shows no signs of cancer after surgery. One group will be watched closely (active surveillance), while the other will receive chemotherapy directly into the bladder (intravesical chemotherapy). The goal is to see if surveillance alone can prevent unnecessary treatment while keeping the cancer controlled.
DaqingAges 18 years+ - NCT07748598Recruiting
Brain scan monitoring for HER2-positive breast cancer
This study is testing regular MRI brain scans to find any brain metastases early in people with HER2-positive breast cancer that has spread. It aims to see if early detection can help guide treatment and improve outcomes.
LiverpoolAges 16 years+ - NCT07669298Recruiting
Monitoring vs chemoradiation for early rectal cancer
This study compares two approaches after early-stage rectal cancer is removed: either careful monitoring or a follow-up treatment with chemotherapy and radiation. The goal is to see which strategy works better to keep the cancer from returning.
LimogesAges 18 years+ - NCT07572370Recruiting
Reducing Follow-up Visits After Breast Cancer Treatment
This study tests whether patients who have finished breast cancer treatment and are doing well can safely have fewer doctor visits and scans. Researchers want to see if reducing routine surveillance affects quality of life and health outcomes.
DublinAges 18 years+ - NCT07513389RecruitingPhase 2
HPV throat cancer trial skipping radiation with blood tests
This study tests whether patients with a specific type of HPV-positive throat cancer can safely skip radiation after surgery by using blood tests to monitor for cancer recurrence. The goal is to reduce side effects while keeping patients cancer-free.
Charleston, South CarolinaAges 18 years+ - NCT07503717Recruiting
Brain scan surveillance in HER2-positive metastatic breast cancer
This study tests whether regular brain scans (surveillance) help spot brain metastases early in people with HER2-positive breast cancer that has spread to other parts of the body. Participation involves being randomly assigned to either routine brain scans or no extra scans to see which approach is better.
BeaumontAges 18 years+ - NCT07470658Enrolling by invitation
Surveillance after positive FIT and normal colonoscopy
This trial studies the best way to follow up with people who had a positive FIT stool test (high blood level) but a normal colonoscopy. It aims to find the right schedule for future screening to catch any problems early.
TaipeiAges 45–74 - NCT06097910Recruiting
Watching multiple lung spots over time
This study is for people who have three or more tiny lung spots (called ground-glass nodules or GGNs) that have not changed in at least three months. The goal is to see if carefully monitoring these spots with regular CT scans is a safe and effective approach.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT07443579Recruiting
Mammogram order study for breast cancer survivors
This trial tests if changing the order of mammogram views makes the exam more comfortable for women who have had breast cancer surgery and radiation. You may be able to join if you are due for your first check-up mammogram after finishing treatment.
Beaumont, DublinAges 18 years+ - NCT04057924Recruiting
Watchful waiting for certain abnormal cells in the cervix
This trial checks whether “therapy abstention” (not treating right away) and close monitoring is safe for certain high-grade cervical cell changes. It may help some people avoid immediate procedures while still catching any progression early.
BordeauxAges 18 years+ - NCT07378930Recruiting
ULTRA-SAFE: More frequent monitoring after advanced polyps
This trial compares a new, more frequent surveillance schedule (yearly stool tests and colonoscopies every 2 years) to the standard schedule for people who have had advanced polyps removed. It aims to see if the extra testing helps prevent future colon cancer.
Taipei, TaipeiAges 40–75 - NCT07370675Recruiting
Active surveillance for Bethesda IV thyroid nodules
This study is testing whether it is safe to simply monitor (watch closely) a small thyroid nodule that has a certain biopsy result (Bethesda IV) instead of removing it right away. You would not receive a treatment, but would have regular checkups and ultrasounds to see if the nodule changes.
CopenhagenAges 30 years+ - NCT07357298RecruitingPhase 3
Brain MRI surveillance for stage IV breast cancer
This trial tests whether regular brain MRI scans can help detect brain metastases early in patients with stage IV breast cancer who do not yet have any known brain metastases. The goal is to see if early detection improves outcomes.
Miami, FloridaAges 18 years+ - NCT07351461Recruiting
Anxiety in men on active surveillance for early prostate cancer and their partners
This study looks at anxiety levels in men who have chosen active surveillance for early prostate cancer, as well as in their partners or significant others. It aims to understand how this approach affects emotional well-being.
