Probiotics for bowel function after rectal cancer surgery
This trial tests whether taking a probiotic supplement (Clostridium butyricum) can improve gut health and bowel function after surgery for very low rectal cancer. It may help patients who have a temporary ileostomy and are planning to have it reversed within 6 months.
Shanghai, Shanghai MunicipalityAges 18–75 - 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.

Study of radiation plus chemo and immunotherapy for rectal cancer
This trial tests a combination of radiation, chemotherapy (CAPOX), and immunotherapy (iparomlimab and tuvonralimab) given before surgery for locally advanced rectal cancer. The goal is to see if this approach can shrink tumors and improve outcomes.

AmiensAges 18 years+ - NCT06923345RecruitingPhase 2
Modified long-course radiation and chemo with immunotherapy for rectal cancer
This trial tests a treatment plan involving radiation, chemotherapy, and an immunotherapy drug (a PD-1 inhibitor) for people with a specific type of high-risk rectal cancer. The goal is to see if this combination helps shrink the tumor before surgery.
Guangzhou, GuangdongAges 18–75 - NCT07154173Recruiting
