Guangzhou, GuangdongAges 18–75 - NCT06914245Recruiting
Personalized help for bowel symptoms after rectal cancer treatment
This trial studies how to improve bowel symptoms in people treated for rectal cancer. It tests personalized care plans and looks at different factors that may contribute to bowel problems after surgery or a watch-and-wait approach.
Leuven, Vlaams-BrabantAges 18 years+ - NCT06767007RecruitingPhase 2
Radiation plus immunotherapy for recurrent rectal cancer
This trial studies a combination of SBRT (a precise kind of radiation) and an immunotherapy drug (PD-1 antibody) for people whose rectal cancer has come back in the pelvis and cannot be removed by surgery. The goal is to see if this treatment can shrink the tumor or stop it from growing.
Guangzhou, GuangdongAges 18–75 - NCT05424692Recruiting
Test tumor drug sensitivity to guide after-surgery colon cancer care
This study looks at whether testing a small tumor sample can identify which medicines are more likely to work for colorectal cancer after surgery. The results are used to help choose the best “after-surgery” treatment plan, when you have not had chemotherapy before surgery.
Beijing, Beijing MunicipalityAges 18–75 - NCT05806931RecruitingPhase 2
Alternating two pills plus bevacizumab for advanced colon cancer
This Phase 2 study tests a treatment plan that alternates two cancer pills and adds bevacizumab (a blood-vessel drug) for metastatic colon cancer that has come back or worsened after standard treatment. It may help shrink tumors and slow disease growth after later-line therapy options.
Elizabeth, New JerseyAges 18 years+ - NCT06563388RecruitingPhase 3
SABR for limited metastatic cancer (ID-COMET trial)
This study tests a precise radiation technique called SABR to treat cancer that has spread to a few spots. It aims to see if this approach can help control the cancer better than usual treatment, especially for lung, prostate, colorectal, or other solid tumors with limited spread.
Buffalo, New YorkAges 1 year+ - NCT07529808RecruitingPhase 1/Phase 2
New Drug BHB810 for Advanced Stomach Cancer
This trial tests a new drug called BHB810 for gastric (stomach) and gastroesophageal junction cancer that has stopped responding to standard treatments or has no standard options available. The drug targets a protein called CDH17 found on cancer cells and may help slow or shrink the tumor.
Duarte, CaliforniaAges 18 years+ - NCT06028724Recruiting
Looking for cancer mutations using a blood test
This study uses a blood test (liquid biopsy) to find genetic changes in advanced solid tumors. It may help doctors choose the right treatment and monitor how well it works over time.
Aviano, PordononeAges 18 years+ - NCT05434026Recruiting
Colorectal cancer database study for people having surgery
This study enrolls people with colon cancer found on biopsy and who are able to have surgery. It mainly builds a medical database to help researchers understand care and outcomes, and it depends on you consenting to participate.
BeijingAges Any age - NCT04695782RecruitingPhase 2
Proton radiation for recurrent rectal cancer in the pelvis
This trial studies “pencil beam” proton radiation for rectal cancer that has come back in the pelvis after you already had radiation. It aims to control the recurrence while trying to limit harm to nearby organs.
AarhusAges 18 years+ - NCT05916040Recruiting
MRI-guided treatment for locally advanced rectal cancer
This trial studies a total “before-surgery” treatment plan for locally advanced rectal cancer, using MRI (a detailed scan) to help guide radiation. It may help patients by aiming to shrink the tumor and improve the chance of successful surgery.
Jette, Brussels CapitalAges 18 years+ - NCT07505472RecruitingPhase 2/Phase 3
Short radiation plus chemo and immunotherapy for high-risk rectal cancer
This trial tests a new approach for people with locally advanced rectal cancer that has high-risk features. It combines short-course radiation with chemotherapy (CapeOX) and the immunotherapy drug toripalimab, with or without another drug called surufatinib, before surgery. The goal is to see if adding these drugs helps shrink the tumor and improve outcomes.
Changchun, JilinAges 18–75 - NCT07183865RecruitingPhase 2
Radiation, chemo, and immunotherapy for recurrent rectal cancer
This trial tests a new combination of radiation, chemotherapy (NALIRIF), and an immunotherapy drug (PD-1 antibody) for rectal cancer that has come back in the pelvis. The goal is to see if this approach can help control the cancer better.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05338866Enrolling by invitation
Chemo plus targeted high-dose radiation for low rectal cancer
This trial tests whether combining chemotherapy with high-dose radiation guided by MRI (a special scan) can better treat low rectal cancer. It may help shrink the tumor and improve local control while targeting the tumor more precisely.
Guangzhou, GuangdongAges 18–80 - NCT05696002Recruiting
Track outcomes after advanced pelvic cancer surgery
This study follows people who have advanced pelvic cancer surgery that removes more than one pelvic organ. It’s an observational study, meaning it mainly collects data to help improve how future surgeries and care are planned.
GlasgowAges Any age - NCT04842812RecruitingPhase 1
Personalized immune cell therapy for advanced solid tumors
This Phase 1 study tests engineered immune cells (TILs/CAR-TILs) made from your tumor to treat advanced solid cancers that have not responded to standard treatments. It may help your immune system better recognize and attack the cancer, but it is mainly focused on safety and early results.
GuangzhouAges 18–85 - NCT05772923Recruiting
Testing rectal cancer organ-preservation after radiation
This trial compares two ways to preserve the rectum/avoid major surgery after radiation: a focused contact x-ray treatment versus waiting longer and then removing only a small area if needed. It may help some people keep more normal bowel function while still controlling the cancer.
Nijmegen, GelderlandAges 18 years+ - NCT06222255Recruiting
Transanal irrigation for sleep issues after rectal cancer surgery
This trial tests if a special irrigation technique can improve sleep problems caused by low anterior resection syndrome (LARS) after rectal cancer surgery. It may help people who have ongoing bowel symptoms that disrupt sleep.
Seoul, Jongro-guAges 19–80 - NCT07605611Recruiting
Somatostatin and Diet vs. Stoma After Rectal Cancer Surgery
This trial tests whether using a medication called somatostatin plus a clear liquid diet can safely prevent serious complications after surgery to remove rectal cancer, without needing a temporary opening in the abdomen (stoma). You'll be randomly assigned to receive either somatostatin with diet changes or a stoma, depending on your individual risk factors.
Ezhou, HubeiAges 18–75 - NCT07566559Recruiting
Rectal Cancer Treatment Before Surgery Study
This study follows real-world treatment of locally advanced rectal cancer (cancer that has grown into nearby tissues but hasn't spread to distant organs) in patients who receive chemotherapy and/or radiation before surgery. Researchers track how different treatment approaches work to help improve outcomes.
Beijing, Beijing MunicipalityAges 18 years+ - NCT07209787RecruitingPhase 4
Reinforced vs. standard connection for rectal cancer surgery
This trial tests whether a special reinforcement patch (made from pig tissue) can reduce the risk of leaks when the rectum is reconnected after rectal cancer surgery. It compares the reinforced connection to the standard method.
Beijing, Beijing MunicipalityAges Up to 85 years - NCT06880055Recruiting
Shield blood test for colorectal cancer screening
This study is testing the Shield blood test for people at average risk of colorectal cancer. It looks at how well the test works for screening, so you can learn about your risk with a simple blood draw.
Chandler, ArizonaAges 45–81 - NCT06274190Recruiting
Better bowel symptom tracking after rectal cancer treatment
This study develops an electronic diary to help track and manage bowel symptoms after rectal cancer surgery or active surveillance. It aims to create personalized care plans to improve your quality of life.
Leuven, Vlaams-BrabantAges 18 years+ - NCT07104604RecruitingPhase 2
New combo before surgery for low rectal cancer
