This trial tests giving mFOLFIRINOX chemotherapy after curative surgery for people with high-risk stage III colon cancer. It aims to lower the chance that cancer comes back.
DaejeonAges 20–75 - NCT05212454RecruitingPhase 3
Capecitabine added after surgery for high-risk ER-positive breast cancer
This Phase 3 study tests whether adding capecitabine (a chemotherapy pill) after breast cancer surgery can lower the chance the cancer comes back. It targets people with hormone-receptor–positive and HER2-negative breast cancer who are considered “high risk.”
Hanzhou, ZhejiangAges 18–70 - NCT05288777RecruitingPhase 2/Phase 3
Testing follow-up chemo and radiation for high-risk breast cancer
This trial studies a standard follow-up treatment plan that combines chemotherapy and radiation after surgery, and it looks for blood/tissue “biomarkers” that predict who benefits most. If you have high-risk breast cancer that didn’t fully disappear after initial (neoadjuvant) chemo, you may be eligible to help guide better future treatment choices.
Charlottesville, VirginiaAges 18 years+ - NCT05313815Recruiting
Test a stronger prostate radiation boost for high-risk prostate cancer
This trial studies whether giving a moderate “boost” dose of radiation to the prostate—along with radiation to the pelvic area—can better control high-risk localized prostate cancer. You may benefit if you have high-risk disease and can safely receive radiation.
Toronto, OntarioAges 18 years+ - NCT05350475Recruiting
Prostate cancer radiotherapy with protons versus photons
This trial compares two types of radiation—protons versus photons—for high-risk localized prostate cancer. It aims to see which option works well while causing fewer problems for nearby organs.
Copenhagen, Capital RegionAges 18 years+ - NCT05384535Recruiting
Test a special MRI to screen high-risk prostate cancer
This study checks whether a detailed MRI method can help find prostate cancer earlier in people considered high risk. You may be asked to get an MRI and help the team see if it works well as a screening test.
Lake Success, New YorkAges 40–55 - NCT05384769Recruiting
Blood test for early lung cancer screening in high-risk people
This study checks whether a blood test (a liquid biopsy) can be used along with standard lung cancer screening to find lung cancer early in people at higher risk. It may help see if the blood test is practical and useful for screening—without needing symptoms.
Duarte, CaliforniaAges 50–80 - NCT05448547RecruitingPhase 3
Tested curative vs conservative treatment for older men with high-risk prostate cancer
This Phase 3 study compares an immediate curative treatment plan versus a more conservative approach in men age 75 and older with newly diagnosed, high-risk prostate cancer. The goal is to see which strategy controls the cancer while better protecting quality of life.
CopenhagenAges 75 years+ - 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+ - NCT05463796Recruiting
Prevention and early detection for people at high cancer risk
This study looks at surveillance (watching closely), prevention, and early “interception” steps to lower the chance that cancer will develop or be found later. It is for people with genetic risk, past cancer treatment exposures, strong family history, or certain early pre-cancer or high-risk conditions.
Boston, MassachusettsAges Any age - NCT05557487Recruiting
Real-world low-dose CT screening for people at high lung risk
This study looks at how people at high risk for lung cancer use low-dose CT scans in real life, and what outcomes happen over time. It may help confirm which groups benefit most from regular screening and support safer screening decisions.
Taichung, TaiwanAges 20–80 - NCT05593497RecruitingPhase 2
Study of hormone therapy plus capivasertib before prostate surgery
This Phase 2 trial tests whether adding capivasertib to intensified hormone therapy (leuprolide plus abiraterone) given before prostate surgery can improve outcomes for men with high-risk localized prostate cancer that has a specific tumor marker (PTEN loss). You would also have extra blood tests, scans, and a tissue biopsy for tumor testing.
West Los Angeles, CaliforniaAges 18 years+ - NCT05726292RecruitingPhase 2
Enzalutamide plus relacorilant versus placebo for high-risk prostate cancer
This study tests whether adding relacorilant to enzalutamide (a hormone-blocking treatment) helps control high-risk localized prostate cancer better than enzalutamide plus a dummy pill. It may help prevent the cancer from growing or spreading by targeting a hormone pathway in addition to standard treatment.
Chicago, IllinoisAges 18 years+ - NCT05806515RecruitingPhase 2
Carboplatin before surgery for high-risk BRCA prostate cancer
This trial tests giving the chemotherapy drug carboplatin before surgery to treat people with high-risk prostate cancer and an inherited BRCA1 or BRCA2 gene change. The goal is to shrink or control the cancer before an operation and improve outcomes.
Anchorage, AlaskaAges 18 years+ - NCT05877573Recruiting
Toripalimab with chemo-radiation before surgery for rectal cancer
This trial studies whether adding toripalimab (an immunotherapy drug) to standard chemo-radiation before surgery can improve outcomes for people with higher-risk, locally advanced rectal cancer. It is meant for cancers that are mismatch-repair “MSS/pMMR,” and it checks safety plus effectiveness as a first treatment.
Guangzhou, GuangdongAges 18–75 - NCT05898594Recruiting
Lung cancer screening for high-risk Black adults
This study is designed to help Black adults at higher risk get lung cancer screening. It checks whether a screening approach can catch lung problems early and connect people to the right next steps.
Chicago, IllinoisAges 50–80 - NCT05906407Recruiting
Genetic-guided treatment planning for high-risk early breast cancer
This study uses tumor genetic testing to help plan more precise treatment for people with early high-risk breast cancer. You may be asked to give a recent tumor sample so researchers can match your cancer features with the best available options.
AugsburgAges 18–80 - NCT05931419Recruiting
Radiation versus surgery for high-risk prostate cancer
This trial compares two standard treatment options—radiation or surgery—for people with high-risk prostate cancer that has not spread. The goal is to see which approach works better for long-term cancer control and side effects.
AlkmaarAges 50–75 - NCT05954078RecruitingPhase 3
ctDNA-guided chemotherapy after colon cancer surgery
This trial checks whether a special blood test (ctDNA methylation) can help decide the best chemotherapy after surgery for people at higher risk of colon cancer coming back. It may help spare some patients unnecessary treatment while aiming to improve outcomes for those likely to relapse.
Shanghai, Shanghai MunicipalityAges 18–80 - NCT05976412Recruiting
Radiation to lymph nodes after surgery for higher-risk breast cancer
This trial looks at whether adding targeted radiation to lymph nodes after breast surgery can lower the chance of breast cancer coming back in people with higher-risk, node-negative disease. If you qualify, you may get a planned radiation approach designed for prevention, not treatment of spread.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT06016569Recruiting
Breath test for early lung cancer in high-risk smokers
This study tests a new breath test to find early signs of lung cancer in people at high risk. It looks for cancer biomarkers in the air you breathe out. If you are a heavy smoker between 55 and 74, this trial may help detect lung cancer earlier.
BrnoAges 55–74 - NCT06056830RecruitingPhase 3
PET scan for high-risk prostate cancer before surgery
This trial uses a special PET scan to find prostate cancer cells before surgery. It may help doctors see where the cancer is located and if it has spread.
Birmingham, AlabamaAges 18 years+ - NCT06122896RecruitingEarly Phase 1
Screening for pancreatic cancer in high-risk people
This trial uses MRI and endoscopic ultrasound to look for early signs of pancreatic cancer in people who have a high risk due to their genes or family history. Finding it early may lead to better treatment options.
Boston, MassachusettsAges 18 years+ - NCT06130995RecruitingPhase 1
Relugolix and enzalutamide for high-risk prostate cancer
This trial tests a combination of two oral drugs, relugolix and enzalutamide, in men with high-risk prostate cancer that hasn't spread to distant parts of the body. The goal is to see if this treatment can help control the cancer before or alongside local therapies like surgery or radiation.
