PIPAC plus chemo for limited peritoneal stomach cancer
This trial tests a treatment called PIPAC (medicine delivered into the abdomen through a small scope) along with “multimodal” therapy, including chemotherapy, for stomach cancer that has spread only in the lining of the abdomen in limited amounts. It may help control the cancer and prevent progression after surgery.
VeronaAges 18–75 - NCT05992220RecruitingPhase 2
Immunotherapy with or without radiation for liver cancer
This trial tests a combination of two immunotherapy drugs (atezolizumab and bevacizumab) with or without targeted radiation therapy for liver cancer that has invaded the major blood vessels of the liver. The goal is to see if adding radiation helps shrink tumors or slow the disease.
SeoulAges 20–79 - NCT06799832Recruiting
Guiding fluid management during major abdominal surgery using a new index
This study tests whether a new tool, the urethral perfusion index, can help doctors better manage fluids during and after major abdominal surgery. It uses standard catheters already in place, so there's no extra device needed.
HamburgAges 45 years+ - NCT06840665RecruitingPhase 2
Radiation plus immunotherapy and chemo for rectal cancer
This trial combines a special type of radiation (MRI-guided adaptive radiotherapy) with an immunotherapy drug (PD-1 antibody) and chemotherapy (CAPOX) for locally advanced rectal cancer. The goal is to see if this combination can improve treatment outcomes.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT07371273RecruitingPhase 2
Comparing three surgeries for low rectal cancer
This trial tests three different surgical methods for rectal cancer located very close to the anal canal. The goal is to see which method works best in the short and long term while preserving anal function.
ShanghaiAges 18–75 - NCT07374731Recruiting
Finding early signs of stomach cancer risk
This study looks for markers in the blood that could show if someone is at risk for stomach cancer or pre-cancerous changes. It aims to help catch problems earlier.
Aviano, PordenoneAges 18–100 - NCT07378631Recruiting
Chronic radiation bowel disease study
This study looks at how different types of chronic radiation enteropathy, a bowel condition caused by radiation therapy, are linked to patient outcomes. It may help doctors better predict how the condition progresses.
Guangzhou, GuangdongAges 18–80 - NCT07372300RecruitingPhase 3
Heat therapy plus standard care for advanced rectal cancer
This trial tests whether adding modulated electro-hyperthermia (a gentle heat treatment) to standard therapy (radiation and chemotherapy) before surgery helps control locally advanced rectal cancer. It is for people whose cancer has not spread to other parts of the body.
Chiayi City, Dalin TownshipAges 20 years+ - NCT07376980Enrolling by invitation
Modified single-stapled anastomosis for rectal cancer surgery
This trial is testing a modified surgical technique (single-stapled anastomosis) for removing part of the rectum in people with rectal cancer. The goal is to see if this approach can improve recovery or outcomes while using minimally invasive methods like laparoscopic or robotic surgery.
Suwon, Gyeonggi-doAges 19 years+ - NCT07375680Recruiting
Blood sugar and stomach emptying study before surgery
This study uses a simple stomach ultrasound before surgery to see how fast your stomach empties. It compares that to your HbA1c (a measure of average blood sugar) to better understand how diabetes might affect digestion during anesthesia.
Kütahya, KütahyaAges 18–70 - NCT07377188Recruiting
Pregnancy and Inflammatory Bowel Disease Study
This trial looks at how pregnancy affects and is affected by inflammatory bowel disease. It aims to learn more to help women with IBD who are or want to become pregnant.
AmiensAges 18–50 - NCT07376577Recruiting
Sedation for older adults having ERCP
This trial tests a combination of two sedatives (anricofen and ciprofol) for deep sedation in older adults having an ERCP procedure. It aims to see if this combination is safe and effective for patients between 60 and 90 years old with mild to moderate health conditions.
Xinxiang, HenanAges 60–90 - NCT07371832Recruiting
Comparing smart staplers with standard staplers in colorectal cancer surgery
This study tests a new, computer-assisted stapler against the usual stapler used during surgery to remove colorectal cancer. The goal is to see if the new stapler works better at safely joining the bowel back together after the cancer is removed.
Hyderabad, TelanganaAges 18–85 - NCT07371247Enrolling by invitationEarly Phase 1
Adjuvant treatment guided by ctDNA after chemoradiation for esophageal cancer
This trial tests whether adjusting treatment based on a blood test (ctDNA) after standard chemoradiation can improve outcomes for patients with advanced esophageal squamous cell carcinoma. It aims to find a more personalized approach to prevent cancer recurrence.
Nanjing, JiangsuAges 18–80 - NCT07375420Recruiting
Exercise before treatment for oesophageal cancer
