Personalized treatment testing with tumor models for esophageal cancer
This trial tests whether a personalized treatment plan, chosen using a lab-grown model of your tumor, works better than standard therapy for esophageal cancer that can be surgically removed. It aims to find the most effective drugs for you before surgery.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT07054879Recruiting
Using a blood test to guide treatment after pancreatic cancer surgery
This trial is for people who had surgery for pancreatic cancer and are now deciding on maintenance therapy. A special blood test (ctDNA) may help doctors choose the best follow-up treatment to prevent the cancer from coming back.
Nanjing, JiangsuAges 18 years+ - NCT07056010Recruiting
Minimally invasive surgery for advanced stomach cancer after chemoimmunotherapy
This trial tests a minimally invasive surgery for stomach cancer that has spread to lymph nodes near the main blood vessels (para-aortic area). The surgery is done after a combination of chemotherapy and immunotherapy to shrink the tumor. It aims to see if this approach is safe and effective.
Nanjing, JiangsuAges 18–80 - NCT07056374Recruiting
New bowel connection method for colon or rectal cancer surgery
This trial tests a new way of connecting the bowel after removing cancer or precancerous lesions in the sigmoid colon or upper rectum. It is for patients who are having planned, curative surgery and may help reduce complications.
AmsterdamAges 18 years+ - NCT07057466Recruiting
AI heart check for hidden valve, pressure, or pump problems
This study uses an artificial intelligence (AI) program to read your ECG (a heart tracing) and detect early signs of heart failure, high blood pressure in the lungs, or valve disease before you have symptoms. The goal is to see if AI can catch these problems early.
BristolAges 18–90 - NCT07059299RecruitingPhase 1
Immunotherapy plus chemo before stomach/esophagus cancer surgery
This trial tests adding an immunotherapy drug (tislelizumab) to standard chemotherapy (FLOT) before surgery for people with stomach or esophagus cancer that can be removed but hasn't spread. The goal is to see if this combination is safe and works better than chemotherapy alone.
FrankfurtAges 18 years+ - NCT07059351Recruiting
Mouth health and pneumonia risk after stroke
This study looks at how oral health affects the chances of developing pneumonia after a stroke and how well people recover their ability to swallow. It may help find ways to prevent complications and improve recovery for stroke survivors with swallowing problems.
