Recruiting studies
- NCT06039917Recruiting
Automatic reminders for stomach precancer follow-up
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+ - NCT05870969Recruiting
Digital monitoring to catch liver cancer risk early
This study tests a digital (computer/phone-based) system to help track people with higher risk of liver cancer so cancers can be found earlier. It may help by guiding regular check-ins and making early diagnosis more efficient.
Shanghai, Shanghai MunicipalityAges 18–75 - 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 - 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 - 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+ - 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 - NCT05875038Recruiting
Smart fall-monitoring video with telealerts versus alerts alone
This study tests whether a smart video monitoring system with emergency-style alerts works better than alerts alone for preventing or responding to falls at home. It focuses on older adults who have recently fallen and may find returning home unsafe.
Amiens, PicardieAges 75 years+ - NCT05740111Enrolling by invitation
Watching early for pancreatic cancer in people at high risk
This study tests a personalized “watch and check” plan to help find pancreatic cancer as early as possible in people with a strong family history or certain inherited gene changes. It may help doctors tailor how often you’re monitored based on your risk.
OsloAges 30–80 - NCT04731610Recruiting
Radiation after thymoma surgery versus watchful waiting
This trial compares two approaches after complete surgical removal of stage IIb or III thymoma: targeted radiation (conformal post-operative radiotherapy) or no further treatment right away (surveillance). It aims to see whether adding radiation lowers the risk of the cancer coming back without causing unacceptable side effects.
CaenAges 18–75 - NCT04875325Enrolling by invitation
Monitoring for pancreatic cancer coming back after surgery
This study looks at a standardized plan for check-ups to detect pancreatic cancer returning after surgery. It may help find recurrence earlier and guide what follow-up care you might need next.
Nijmegen, GelderlandAges 18 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 - NCT04558593Recruiting
Watching complex kidney cysts with regular scans
This study monitors people who have complex kidney cysts to see how they should be followed over time and whether it helps guide treatment. You may get regular imaging (scans), and you’ll be asked to complete questionnaires in English or French.
Calgary, AlbertaAges 18 years+ - NCT06337097Recruiting
Monitoring heart enzyme during immunotherapy
This study is for people starting immunotherapy with checkpoint inhibitors. It checks a heart enzyme (troponin) to see if the treatment affects your heart, so your doctor can monitor and manage any changes early.
Houston, TexasAges 18 years+ - NCT07121517Recruiting
Predicting airway problems in children with tracheostomies
This study looks at children with tracheostomies to see if symptoms you or your doctor notice can predict airway problems found during a routine scope. Participation involves no extra procedures—just answering questions and giving permission to use information from that routine scope.
SolnaAges Up to 18 years - 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 - 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+ - 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+ - 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+ - NCT04677998Recruiting
Personalized monitoring and treatment plan for stomach polyps
This trial tests a personalized plan for regularly checking and treating stomach and first-part of intestine polyps in people with familial adenomatous polyposis (FAP). It may help by catching problems early and choosing the right intervention at the right time.
Houston, TexasAges 18 years+ - NCT04678011Recruiting
Personalized follow-up to prevent cancer after FAP surgery
This trial studies a tailored plan for surveillance (check-ups) and interventions to find and remove new growths early in people with familial adenomatous polyposis (FAP) after bowel surgery. It may help lower the chance of cancer by closely monitoring and treating polyps when they appear.
Houston, TexasAges 18 years+ - NCT04967183Recruiting
Compare a stool blood test versus colonoscopy follow-up after precancer removal
This study compares two ways of checking for colorectal cancer risk after advanced polyps are removed. It may help determine whether a stool test can safely replace some colonoscopy surveillance for certain people.
OurenseAges 50–65 - NCT05454280RecruitingPhase 3
Manage surgical risk after high-risk cancer operations
This study looks at a “risk-based plan” to help guide care after major cancer surgery, aiming to improve recovery and outcomes. You may be in the study when you’re about to have elective (planned) high-risk cancer surgery and then again just before hospital discharge.
Philadelphia, PennsylvaniaAges 18 years+ - NCT05658172Recruiting
Less vs more frequent follow-up after early breast cancer
This trial compares standard follow-up visits versus more intensive follow-up for people with early breast cancer after their main treatment. The goal is to see whether closer monitoring finds problems earlier or improves outcomes.
