Guangzhou, GuangdongAges 18 years+ - NCT07649057Recruiting
Urine Test for Early Colorectal Cancer Detection
This study tests whether a simple urine sample can detect colorectal cancer or precancerous polyps. Researchers want to see if this non-invasive test could help identify people at risk before symptoms develop or catch cancer earlier.
New York, New YorkAges 18 years+ - NCT03280511RecruitingPhase 2
After surgery chemo sprayed into the abdomen for high-risk colon cancer
This Phase 2 study tests whether spraying chemotherapy into the abdomen (through a small procedure) after colon cancer surgery can lower the chance the cancer comes back. It is meant for people with high-risk tumor features but who have had surgery and have no proven relapse yet.
OdenseAges 18 years+ - NCT04006951Recruiting
Registry study for people with rectal cancer in Montpellier
This is a hospital-based study that builds a clinical and biological database for people treated for rectal cancer at the Montpellier Cancer Institute. It helps researchers organize health information to better understand rectal cancer and improve future care.
MontpellierAges 18 years+ - NCT05365412Recruiting
Study of colon cancer in younger adults
This study looks at the clinic and lab features of colon cancer in people diagnosed at a young age. Your information from your diagnosis and treatment may help doctors understand how colon cancer differs by age.
Seongnam-si, Gyeonggi-doAges 18 years+ - NCT06576986Recruiting
Can a supplement prevent mouth sores during chemo?
This trial tests whether a special supplement (synbiotic) can prevent mouth sores caused by chemotherapy in people with colorectal cancer. It's for those starting treatment who live in or near Belo Horizonte, Brazil.
Belo Horizonte, Minas GeraisAges 18 years+ - NCT06854679Recruiting
MRI-guided radiation for rectal cancer
This trial tests a new way of giving radiation therapy for rectal cancer, using MRI scans to aim the radiation more precisely. It's for people who need chemotherapy and radiation before surgery, and it aims to make treatment more effective while reducing side effects.
Sutton, SurreyAges 18 years+ - NCT06972160Recruiting
Boosting colorectal cancer screening in Barcelos/Esposende
This study looks at ways to help more people get screened for colorectal cancer. If you're between 50 and 74 and haven't had certain screenings recently, you may be able to join.
PortoAges 49–75 - NCT07369531Recruiting
Stoma-free survival after new anal-sparing surgery for low rectal cancer
This study compares a two-stage surgical technique (Turnbull-Cutait pull-through) to standard surgery for people with low rectal cancer. The goal is to see which approach helps more patients avoid a permanent stoma (bag) after surgery.
Changchun, JilinAges 18–75 - NCT06926374Recruiting
Robotic surgery for gastrointestinal and urologic conditions
This trial tests a new robotic surgery system for common operations on the colon, rectum, prostate, kidney, bladder, stomach, esophagus, gallbladder, and hiatal hernia. It may offer a less invasive option for patients who need surgery for these conditions.
Hong KongAges 18–80 - NCT07750951RecruitingPhase 2
Combination therapy before surgery for advanced rectal cancer
This trial tests a combination of two immunotherapy drugs and chemotherapy given before surgery for a type of rectal cancer that has a specific genetic marker (MSI-H/dMMR). The goal is to shrink the tumor and improve the chances of successful surgery.
Xi'an, ShaanxiAges 18 years+ - NCT04936581Recruiting
Quality of life after rectal cancer surgery
This study looks at patient-reported outcomes—how you feel and function—after surgery for rectal cancer. It may help doctors better understand recovery and well-being after different surgical approaches and treatments.
