Wuhan, HubeiAges 18–75 - NCT07337811Recruiting
Selective removal of rectal cancer after radiation and chemotherapy
This trial tests how well a precise surgery removes the remaining rectal cancer after you have had radiation and chemotherapy. It is for people whose tumor has shrunk a lot but is still there, and the tumor is very low in the rectum.
Guangzhou, GuanggongAges 18–75 - NCT07514754Recruiting
Immunonutrition support during cancer treatment
This study tests whether special nutritional support (called immunonutrition) helps patients with head and neck, lung, or rectal cancer who are receiving chemotherapy, radiation, or immunotherapy. The goal is to see if it improves how well treatment works and how you feel during and after cancer care.
Candiolo, Torino (TO)Ages 18 years+ - NCT07511413Recruiting
Monitoring health in head, neck, lung & rectal cancer
This trial is studying how a monitoring method (bioimpedance) works for people with head and neck, lung, or rectal cancer who are about to start standard treatment. It may help doctors track your health better during therapy.
Candiolo, Torino (TO)Ages 18 years+ - NCT07107815Enrolling by invitation
Predicting rectal cancer treatment response using MRI
This study uses advanced MRI scanning and computer analysis to predict how well rectal cancer might respond to treatments given before surgery. It may help doctors choose the best approach for you.
Beijing, Beijing MunicipalityAges Any age - NCT07702799Recruiting
Low-fiber diet vs enema before laparoscopic endometrial cancer surgery
This trial compares two colon preparation methods — a low-residue diet versus a rectal enema — before laparoscopic surgery for endometrial cancer. The goal is to find which approach is easier and works better for bowel preparation.
IstanbulAges 18–90 - NCT07721181Recruiting
STEP-UP: Higher radiation for recurrent rectal cancer
This trial tests giving a higher dose of radiation to people whose rectal cancer has come back in the pelvis after surgery and cannot be removed. It aims to see if more radiation can help control the tumor when surgery is not an option.
Maastricht, LimburgAges 18 years+ - NCT04245683Recruiting
Testing non-surgical treatment for newly diagnosed rectal cancer
This study looks at whether it’s practical and safe to treat certain rectal cancers without surgery. You may be offered non-surgical (“neoadjuvant”) treatment and close follow-up to see how well it works in a rural setting.
Cooperstown, New YorkAges 18 years+ - NCT03908684Recruiting
Ultrasound tests to predict early response to prostate and head/neck radiation
This study uses special ultrasound imaging to look for early signs of how well radiation treatment is working in prostate, rectum, and head/neck cancers. It may help doctors spot response sooner and adjust care earlier if needed.
Toronto, OntarioAges Any age - NCT07866313RecruitingPhase 2/Phase 3
Chemotherapy, radiation, and immunotherapy before surgery for low rectal cancer
This trial tests a new combination of chemotherapy, radiation, and immunotherapy given before surgery for low rectal cancer. It aims to see if this approach can shrink tumors and improve outcomes for patients with a specific type of cancer that is microsatellite stable (MSS).
Shanghai, Shanghai MunicipalityAges 18–75 - NCT07395505Enrolling by invitation
Surgery for advanced rectal or anal cancer
This trial studies the results of a major surgery called pelvic exenteration for patients with advanced rectal or anal cancer that has spread to nearby tissues or bones but not to distant organs. The goal is to see how well the surgery works and how patients recover afterward.
TaoyuanAges 20 years+ - NCT07132463RecruitingPhase 3
Study of extra treatment for ultra-low rectal cancer
This trial tests if adding an immunotherapy drug (tislelizumab) to standard chemoradiation and chemotherapy helps patients with ultra-low rectal cancer. It is for patients whose cancer has not spread and can be removed with surgery.
ShanghaiAges 18–75 - NCT07070622RecruitingPhase 3
Organ preservation for low rectal cancer after chemo
This trial tests whether chemotherapy alone can help avoid surgery for low rectal cancer. It is for people with tumors close to the anus that haven't spread far, and who haven't had prior cancer treatment.
Chengdu, SichuanAges 18–80 - NCT07005570RecruitingPhase 2
Short radiation and chemo with or without immunotherapy for rectal cancer
This trial tests if adding an immunotherapy drug (PD-1 inhibitor) and a targeted therapy (bevacizumab) to short-course radiation followed by chemo can improve outcomes for patients with locally advanced rectal cancer that is pMMR/MSS. The goal is to shrink the tumor before surgery and possibly avoid the need for more extensive treatment.
Guangzhou, GuangdongAges 18–75 - NCT06958432RecruitingPhase 2/Phase 3
Shorter radiation before chemo and immunotherapy for rectal cancer
This trial tests a shorter course of radiation before chemotherapy and an immunotherapy drug to shrink mid-to-lower rectal cancer that has not spread. The goal is to improve treatment response and reduce side effects, potentially allowing for less invasive surgery.
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.
