Surgery timing after chemoradiation for esophageal cancer
This study looks at whether having surgery at the right time after chemoradiation improves outcomes for people with esophageal cancer. You might qualify if you have had (or are planning) chemoradiation and then are going to have surgery to remove the tumor.

Pregnancy follow-up after patisiran exposure
This program tracks pregnancy outcomes for people who were exposed to patisiran (a medicine) in a special delivery form called LNP during pregnancy or shortly before. It helps doctors understand potential effects and safety for mothers and babies.
Iowa City, IowaAges Any age - NCT05095714Recruiting
Fast MRI for close monitoring of high-risk liver cancer
This trial studies a faster MRI scan to help track early liver cancer in people who have cirrhosis and are considered high risk. It may improve how often and how well doctors can look for changes without using longer imaging sessions.
BondyAges 18 years+ - NCT05103254Recruiting
Pregnancy monitoring for bempedoic acid medicine use
This study follows people during and after pregnancy who took bempedoic acid (either alone or with ezetimibe). It collects safety information to better understand how this medicine may affect pregnancy outcomes.
Morrisville, North CarolinaAges 18 years+ - NCT05234177Recruiting
Blood test to track colorectal cancer after surgery
This study looks at a blood “DNA” test to see if it can help monitor colorectal cancer after surgery. It may benefit you by improving how doctors track cancer during routine follow-up visits.
Fort Smith, ArkansasAges 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+ - NCT05293470Recruiting
Tracking the real-world effects of Piqray in Korea
This study monitors how well and how safely Piqray works for people in Korea in routine care. You may be invited if your breast cancer matches specific genetic and receptor test results and you are starting Piqray for the first time.
Cheonan Si, Chungcheongnam-doAges 18–100 - NCT05299762Recruiting
INFUSE bone graft for lower back fusion: patient follow-up study
This study tracks patients who receive INFUSE bone graft during a specific type of lower back fusion surgery. It helps confirm how the device performs in real-world care and monitors safety and outcomes after surgery.
SeoulAges 18 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 - NCT05346757Recruiting
Test stool DNA changes to screen or find colorectal cancer
This study checks whether a stool test that looks for tiny genetic signals can help detect colorectal cancer (or find it again after prior findings). You may be asked to provide a stool sample around the time you get a colonoscopy.
BarcelonaAges 18–80 - NCT05355363Recruiting
Check what happens after missed colon follow-up for colon polyps
This study looks at the risk of new or advanced colon findings in people who had certain colon polyp results, but then did not get the recommended follow-up colonoscopy on time. It may help doctors fine-tune how urgently different patients need repeat colon checks.
Montreal, QuebecAges 45–80 - 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+ - NCT05372263Recruiting
Tracking safety of pulmonary hypertension medicines by computer follow-up
This study checks how safe pulmonary hypertension–targeted medicines (and some calcium-blocking medicines) are over time. It uses a computer system to follow you after diagnosis, looking at outcomes and side effects.
Beijing, Beijing MunicipalityAges 3 months–85 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 - NCT05459948Recruiting
Follow-up study for a primary knee replacement
This study tracks outcomes after a standard (first-time) total knee replacement using the GMK SpheriKA implant. It mainly looks at how well the knee works in everyday life, including activity and self-checks over time.
MérignacAges 18–80 - NCT05497024Recruiting
Decision aid testing for older men on prostate cancer surveillance
This trial tests an English decision aid (a patient guide) to help older men understand and feel comfortable with “active surveillance” for localized prostate cancer. It also checks how easy to use it is for patients, caregivers, and prostate cancer clinicians.
Houston, TexasAges 65 years+ - NCT05515367RecruitingPhase 4
Real-world safety study of desidustat for kidney anemia
This study tracks the real-world safety of desidustat in adults with anemia caused by chronic kidney disease (CKD). It’s meant to see whether the medicine is safe when used in everyday care, not just in tightly controlled settings.
Sheikhpura, BiharAges 18–85 - 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 - NCT05553899Recruiting
PET-MRI scans for monitoring children’s brain tumor return
This study checks whether a special scan called PET-MRI can better tell if a child’s brain tumor has come back after treatment. It may help doctors decide faster and more accurately when changes seen on regular MRI are true tumor recurrence.
Sheffield, South YorkshireAges 8–18 - NCT05558241Recruiting
Ultrasound test for men on active surveillance for prostate cancer
This study checks whether a new, small ultrasound approach can help confirm prostate cancer during active surveillance. It may help by providing a safer or more targeted way to decide whether ongoing monitoring is still enough.
Los Angeles, CaliforniaAges 18 years+ - NCT05582122RecruitingPhase 2
Tracking HPV16 DNA in blood to spot cancer coming back
This study checks whether a blood test for HPV16 DNA can predict when HPV-related throat cancer comes back after treatment. It may help improve follow-up care by catching recurrence earlier.
Saint-Denis, La RéunionAges 18 years+ - NCT05598879Recruiting
New heart-cancer visit registry for adults
This study is a “registry,” meaning it collects health information from adults who are getting a new heart (cardio) evaluation related to cancer. It helps doctors better understand heart risks and care needs for different cancer types and treatments.
Weston, FloridaAges 18 years+ - NCT05606133Recruiting
Test HPV DNA from blood to track cervical cancer risk
This study looks at a blood test that measures HPV DNA to help screen and monitor people with HPV-related cervical problems. If you have confirmed high-grade cervical changes or cervical cancer, the test may help doctors follow how your condition changes over time.

Common questions
- Are there clinical trials for surveillance?
- Yes. Clin2 currently lists 309 recruiting surveillance 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 surveillance 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 surveillance 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.
