It aims to see if this treatment approach can help control the disease and improve outcomes in patients with limited spread that can potentially be removed or treated.
RomeAges 18 years+ - NCT07346248Enrolling by invitation
Complications after pre-surgery treatment for advanced rectal cancer
This study looks at complications that happen after surgery in patients with advanced rectal cancer who got radiation or chemo-radiation before their operation. Researchers want to learn how different pre-surgery treatments affect recovery.
Rozzano, MilanAges 18 years+ - NCT07260526Recruiting
Chemo and radiation for low rectal cancer, aiming to avoid surgery
This trial tests whether people with early- to intermediate-stage low rectal cancer can avoid surgery if their tumor responds well to a full course of chemotherapy and radiation. It starts with brief chemotherapy, then adjusts treatment based on how much the tumor shrinks.
Chengdu, SichuanAges 18–80 - NCT06234007RecruitingPhase 2
Short radiation plus combo therapy for advanced rectal cancer
This trial tests a short course of radiation therapy followed by a combination of three drugs (fruquintinib, adebrelimab, and CAPOX chemotherapy) before surgery for people with locally advanced rectal cancer. The goal is to see if this approach can shrink the tumor and improve outcomes.
WuhanAges 18–75 - 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.
MadridAges 18–100 - NCT03671252RecruitingPhase 3
Chemotherapy before surgery for rectal cancer vs chemo with radiation
This Phase 3 trial compares two treatment plans given before rectal surgery. It tests whether stronger chemotherapy alone works better than chemotherapy pills plus long-term radiation to improve outcomes for locally advanced rectal cancer.

Better CT scans for staging rectal cancer
This study tests a new, more detailed type of CT scan (called photon-counting CT) to see if it can better show how far rectal cancer has grown or spread. If you are already getting standard scans to stage your cancer, this study adds an extra CT scan with contrast dye to get clearer pictures.
Rochester, MinnesotaAges 18–99 - NCT05321134Recruiting
Testing single-port robot surgery for colorectal conditions
This study checks how well a newer single-opening (single-port) robot works for colorectal surgery. It may help surgeons perform operations with the robotic system in carefully selected colorectal conditions.
Sacramento, CaliforniaAges 18 years+ - NCT04808323RecruitingPhase 1
MRI-guided radiation to help preserve organs in rectal cancer
This Phase 1 study tests a radiation treatment approach guided by MRI scans to help keep nearby organs functioning while treating rectal cancer. It is designed to find a safe, effective way to target the tumor and adjust treatment during the course of therapy.
Milwaukee, WisconsinAges 18 years+ - NCT04184973Recruiting
Testing a colon bypass device during colorectal cancer surgery
This trial studies a device (CG-100) placed inside the bowel to see if it can improve safety and outcomes during surgery for colorectal cancer. You would be asked to follow extra study check-ins after your operation, and the team would monitor whether the device works as intended.
Irvine, CaliforniaAges 22–70 - NCT06633133Recruiting
Virtual ileostomy vs. diverting ileostomy for rectal cancer surgery
This trial compares a virtual ileostomy (a system that monitors leaks without creating a temporary opening) to a traditional diverting ileostomy (a temporary bag) in people having rectal cancer surgery. The goal is to see if the virtual method is safer and avoids a second surgery.
ChongqingAges 18 years+ - NCT05068531Recruiting
Detecting early treatment failure in stage IV colon cancer
This study looks for early signs that treatment is not working in people with stage IV colon or rectal cancer that has spread only to the liver. It may help doctors adjust care sooner by using regular blood, stool, and tissue samples around liver procedures.
Montreal, QuebecAges 18 years+ - NCT07809893RecruitingPhase 2
New drug combo for advanced colorectal cancer with BRAF mutation
This trial tests a new combination of drugs for people with advanced colorectal cancer that has a specific genetic change called BRAF V600E. The treatment includes a targeted therapy (ivosidenib) plus chemotherapy and a pain-relief drug (celecoxib). It is for people whose cancer has stopped responding to previous treatments, including BRAF-targeted therapies.
Guangzhou, GuangdongAges 18–70 - NCT07221058RecruitingPhase 1
Adaptive radiation boost study for rectal cancer
This study tests whether giving an extra, targeted radiation dose (adaptive radiation boost) after standard treatment can improve outcomes for people with rectal cancer. You may be eligible if you have stage T2-3 N0-1 rectal cancer and can undergo MRI scans and certain chemotherapies.
Philadelphia, PennsylvaniaAges 18 years+ - NCT07223424RecruitingPhase 2
Patient preference study: shot vs infusion for immunotherapy
This study compares two ways to take immunotherapy drugs (nivolumab or pembrolizumab): as a shot under the skin (subcutaneous) versus an infusion into a vein (intravenous). It looks at which method patients prefer and is for people with certain advanced cancers where these drugs are already approved.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT07058012RecruitingPhase 2
Testing immunotherapy for ctDNA-positive colorectal cancer after treatment
This trial is for people with colorectal cancer whose ctDNA blood test is still positive after surgery and chemotherapy. It tests two immunotherapy drugs (cemiplimab alone or with fianlimab) to see if they can eliminate the remaining cancer cells and prevent the cancer from coming back.
Gainesville, FloridaAges 18 years+ - NCT07280143Recruiting
MASLD risk in breast or colorectal cancer survivors
This study looks at whether breast or colorectal cancer survivors are more likely to develop a liver condition called MASLD (fatty liver disease not caused by alcohol). It uses blood tests, imaging, and possibly an MRI to check liver health.
BernAges 18 years+ - NCT07281768RecruitingPhase 2
Chemo and immunotherapy for locally advanced rectal cancer
This trial tests whether adding two types of immunotherapy (cemiplimab with either fianlimab or REGN7075) to standard chemotherapy is safe and effective for people with locally advanced rectal cancer that has not been treated before. It may help shrink the tumor enough to allow surgery that preserves the ability to control bowel movements.
Baltimore, MarylandAges 18 years+ - NCT05065801RecruitingPhase 2
New metastatic pancreatic cancer: targeted chemo before FOLFIRINOX
This trial tests whether adding Gembrax (a combination that includes gemcitabine and nab-paclitaxel) before standard FOLFIRINOX works better than FOLFIRINOX alone in people with pancreatic cancer that has already spread. It looks at whether this “step-up first” approach improves results and is still tolerable.
Grenoble, Auvergne-Rhône-AlpesAges 18–75 - NCT05563922RecruitingPhase 2
Testing a plan to preserve the anus after rectal chemo-radiation
This Phase 2 study tests a “total neoadjuvant” (chemo plus radiation before the main treatment) plan to see if some people with low rectal cancer can keep their anus. It may help you avoid permanent colostomy if your cancer responds well and you meet the study rules.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT06631443Recruiting
Asian Watch-and-Wait Study for Rectal Cancer
This study is for people with rectal cancer who have had treatment like radiation or chemo and their tumor has disappeared or nearly disappeared. Instead of surgery right away, doctors will closely monitor the cancer with regular check-ups to make sure it stays gone.
Mumbai, MaharashtraAges 18 years+ - NCT07558083RecruitingPhase 3
Tracking colorectal cancer response using blood tests
This study tests whether a simple blood test can track how well your colorectal cancer is responding to first-line chemotherapy. By monitoring cancer markers in your blood, doctors may be able to detect treatment changes earlier than traditional imaging.
Mechelen, AntwerpenAges 18 years+ - NCT05601505RecruitingPhase 2
DNA blood test–guided treatment before rectal cancer surgery
This trial uses a special DNA blood test (circulating tumor DNA) to help guide chemotherapy and radiation before surgery for locally advanced rectal cancer. It aims to improve outcomes by tailoring treatment based on the DNA signals from the tumor.
