Recruiting studies
- NCT06649123Recruiting
Rectal mucus test for colorectal cancer diagnosis
This trial is testing a new way to check for colorectal cancer by looking at a sample of rectal mucus. It's for people who have been referred for urgent cancer evaluation and may help find cancer earlier.
Telford, ShropshireAges 18–99 - NCT04854213Recruiting
Study checks radiation effects in colon cancer lung-limited spread
This trial studies how targeted radiation (SBRT) affects cancer biology and immune cells in people with colon cancer that has spread only to a small number of lung nodules. Your tumor tissue will be analyzed to see what changes after treatment.
Naples, NAPOLIAges 18–80 - NCT07692152RecruitingPhase 3
Immunotherapy vs. chemo for MS anal cancer trial
This trial tests sintilimab (a type of immunotherapy) against mitomycin plus chemotherapy with radiation for anal cancer that hasn't spread. It aims to find a better treatment with fewer side effects.
Beijing, Beijing MunicipalityAges 18–75 - NCT05102110Recruiting
Check rectal mucus in people with throat or lung cancers
This study looks at a substance called rectal mucus during an exam to learn about changes in people with cancers of the throat/airways (aero-digestive tract). It’s a feasibility study, meaning it mainly tests whether this approach is safe and practical.
ExeterAges 18–99 - NCT05597852Recruiting
Rectal gel spacer to help repeat prostate radiation
This trial studies whether placing a soft gel spacer near the rectum can make “salvage” prostate radiation safer and more tolerable when prostate cancer comes back locally. It may help reduce side effects by creating extra space between the rectum and the radiation area.
Toronto, OntarioAges 18 years+ - NCT06391034RecruitingPhase 2
MRI scan with pyruvate for prostate cancer
This trial uses a special MRI scan (with hyperpolarized pyruvate, a naturally occurring substance) to look at prostate cancer in more detail. It aims to help doctors understand how the cancer is responding to treatment or how it might behave.
San Francisco, CaliforniaAges 18 years+ - NCT06630962Recruiting
Financial help for newly diagnosed cancer patients
This study looks at whether getting help with financial issues (like insurance and costs) can reduce the money worries and problems that come with cancer treatment. It is for people newly diagnosed with breast, colorectal, or prostate cancer who haven't started treatment yet.
Ile-IfeAges 18 years+ - NCT04035642Recruiting
Single high-dose MRI-guided radiation for intermediate prostate cancer
This trial tests whether a single, image-guided radiation treatment can treat intermediate-risk prostate cancer while better protecting the urethra (the urine tube). It may help patients get effective cancer control with potentially fewer urinary side effects, depending on the results.
LisbonAges 18 years+ - NCT07230639RecruitingPhase 2
Shorter radiation with chemo and immunotherapy for high-risk colon cancer
This trial tests a shorter course of radiation combined with chemotherapy and an immunotherapy drug (PD-1 inhibitor) for people with a specific type of high-risk colon cancer that has not spread. The goal is to see if this approach can shrink the tumor before surgery and improve outcomes.
Guangzhou, GuangdongAges 18–75 - NCT04945642Recruiting
Radiation combination therapy for intermediate to high-risk prostate cancer
This trial studies a combination of two radiation types—high-dose-rate brachytherapy and stereotactic body radiotherapy—to treat certain intermediate- to high-risk prostate cancers. It may help by aiming radiation closely at the prostate while also targeting the cancer from outside the body.
Los Angeles, CaliforniaAges 18 years+ - NCT05546827RecruitingPhase 2
Pre-surgery radiation plus immunotherapy for mucosal melanoma
This Phase 2 trial tests giving radiation and immunotherapy before surgery for mucosal melanoma in the nose/sinuses or rectum. It may help shrink the tumor and improve outcomes while aiming to control the disease locally and in nearby areas.
Houston, TexasAges 18 years+ - NCT06205316RecruitingPhase 3
Radiation therapy for returning or limited-spread prostate cancer
This trial compares two types of radiation therapy for prostate cancer that has come back or spread to a few places after surgery. The goal is to see which radiation schedule works better with fewer side effects.
Scottsdale, ArizonaAges 18 years+ - NCT04749108RecruitingPhase 2/Phase 3
Tailored treatment for locally advanced rectal cancer after FOLFIRINOX
This trial studies a more customized treatment plan for people with locally advanced rectal (bowel) cancer after they receive FOLFIRINOX chemotherapy. It aims to reduce tumor spread risk and improve outcomes by tailoring the next steps based on scan details and your health status.

Common questions
- Are there clinical trials for rectal cancer, radiotherapy?
- Yes. Clin2 currently lists 205 recruiting rectal cancer, radiotherapy 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 rectal cancer, radiotherapy 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 rectal cancer, radiotherapy 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.
