Shanghai, Shanghai MunicipalityAges 18–75 - NCT07419490Recruiting
Moving ovaries and uterus to preserve fertility during pelvic radiation
This trial moves the ovaries and uterus higher in the belly before pelvic radiation to protect them, so patients may still be able to have children later. It is for women aged 18-40 with pelvic cancers that require radiation.
Tampa, FloridaAges 1.5 years–3.3 years - NCT07474103Recruiting
Chemo, radiation, and immunotherapy for high-risk rectal cancer
This trial tests a treatment plan that combines chemotherapy, radiation, and an immunotherapy drug before surgery for people with high-risk locally advanced rectal cancer. The goal is to see if this approach can improve outcomes.
WuhanAges 18–75 - NCT07537998RecruitingPhase 2/Phase 3
Intestinal Fluid Recycling to Reduce Bowel Problems After Rectal Cancer Surgery
This trial tests a surgical technique that recycles intestinal fluids during rectal cancer surgery to help prevent bowel dysfunction and frequent bowel movements after surgery. If you've had mid-to-low rectal cancer removed and created a temporary opening (stoma), this study may help improve your quality of life.
Guangzhou, GuangdongAges 18–75 - NCT07573371Recruiting
Understanding bowel changes after rectal cancer surgery
This study helps doctors better understand and treat bowel control problems that can happen after rectal cancer surgery or other rectal treatments. If you've had this surgery or treatment, the study team wants to learn more about your recovery and test new ways to help.
AalborgAges 18 years+ - NCT07646639RecruitingPhase 2
Radiation, chemotherapy, and immunotherapy for advanced rectal cancer
This study tests a combination of radiation therapy, chemotherapy drugs (capecitabine and oxaliplatin), and two types of immunotherapy (a PD-1 blocker and IL-2) for locally advanced rectal cancer. The goal is to see if this combination helps shrink tumors and improve outcomes before surgery.
Nanjing, JiangsuAges 18–70 - NCT05961969Recruiting
Robotic rectal surgery for early-to-mid rectal cancer
This trial tests a robotic, top-down approach to remove certain rectal tumors using an intersphincteric resection (a surgery that preserves bowel control as much as possible). It may help some people with stage I–III rectal cancer avoid a bigger operation and improve outcomes compared with standard surgical methods.
TaipeiAges 20–75 - NCT05250648RecruitingPhase 4
HIPEC with mitomycin C after surgery for colon cancer in the belly
This study looks at adding a heated medicine treatment (HIPEC with mitomycin C) during surgery to treat colon cancer that has spread to the lining of the abdomen (peritoneum). It aims to improve outcomes after surgeons remove visible tumor completely.
Elche, AlicanteAges 18 years+ - NCT06931808Enrolling by invitationPhase 4
Fecal transplant with chemo, radiation, and immunotherapy for advanced colon cancer
This study tests a combination of fecal microbiota transplant, chemotherapy, radiation, and immunotherapy (sintilimab) for people with locally advanced rectal cancer. The goal is to see if this approach improves treatment outcomes.
Ningbo, ZhejiangAges 18–75 - NCT03659448RecruitingPhase 3
Test drug that helps map colon and rectal cancer during surgery
This Phase 3 study tests SGM-101, a drug used during surgery to help doctors better outline primary, recurrent, and spread (metastatic) colorectal cancer. It may improve how completely tumors are identified and removed during an operation.
Duarte, CaliforniaAges 18 years+ - NCT05482516RecruitingPhase 3
Testing blood test–guided treatment for GI cancers in remission
This Phase 3 study tests whether giving treatment based on a positive blood test for “minimal cancer signals” (ctDNA) can help people with certain GI cancers stay cancer-free longer. It focuses on people who have finished curative-intent therapy and currently have no visible disease on scans, but their blood test is still positive.
Washington D.C., District of ColumbiaAges 18 years+ - NCT05789433Recruiting
Aerobic exercise study after colon or rectal cancer surgery
This trial studies whether a supervised aerobic exercise program helps muscles “remodel” (change/strengthen) after colon or rectal cancer treatment. It may help people improve physical function during recovery, but you can only join if it’s safe for you and you can follow the study plan.
Orlando, FloridaAges 18 years+ - NCT02292641Recruiting
MRI study for repeat pelvic colorectal cancer
This study uses a special MRI to help understand and stage colorectal cancer that has come back in the pelvis. The goal is to improve how doctors make treatment decisions after previous surgery.
OsloAges 16 years+ - NCT04575935RecruitingPhase 3
Minimally invasive surgery after chemotherapy for advanced ovarian cancer
This trial studies whether doing surgery using smaller incisions after chemotherapy works as well as a more traditional approach for certain people with stage IIIC–IV ovarian, fallopian tube, or primary peritoneal cancer. It may help reduce surgical trauma while aiming for effective tumor removal.
Miami, FloridaAges 18 years+ - NCT05168839RecruitingPhase 3
Using dye scans during surgery to help prevent leakage
This trial tests whether using a special dye and camera during colorectal cancer surgery can help lower the risk of a surgical “leak” where the bowel is joined. If you’re having a planned left-sided colectomy or high rectal resection, the scan may help surgeons see blood flow more clearly.
AmiensAges 18 years+ - NCT05787197Recruiting
Blood test to guide treatment after colon cancer liver surgery
