De-escalating treatment after HER2-positive breast cancer responds
This study looks at whether some people with HER2-positive breast cancer can safely receive less (de-escalated) treatment after they finish chemotherapy plus HER2-targeted drugs before surgery. It specifically focuses on people whose cancer shows a complete response on the surgery pathology report.
São PauloAges 18 years+ - NCT05326295Recruiting
Breast cancer study using tumor cells in blood
This trial checks whether a blood test that looks at tumor cells can help guide treatment for people with breast cancer. If you join, your care team will follow your responses over time to see if this “phenotype surveillance” approach is useful.
Changsha, HunanAges 18–75 - NCT05346536Recruiting
Test blood test for a specific type of pancreatic cancer cell
This trial looks for pancreatic cancer markers in a blood sample (“liquid biopsy”), focusing on cells that show a certain protein (AXL). It may help doctors detect and better track advanced pancreatic cancer before or during first-line treatment.
MontpellierAges 18 years+ - NCT05831631Recruiting
Study immune cells in brain tumors during neurosurgery
This study looks at different immune cells in the blood and inside brain tumors. It includes adults who have a malignant brain tumor and need a neurosurgery procedure, such as surgery, stereotactic biopsy, or radiosurgery, to help doctors better understand the immune response.
Milan, MilanAges 18 years+ - NCT06672250Recruiting
Tumor cells and blood clots in veins
This study looks at the link between tumor cells found in the blood and blood clots in the veins. It is for people who have had or will have a procedure to remove a blood clot, whether they have cancer or not.
New Taipei CityAges 18–80 - NCT06755762Recruiting
3D blood test for advanced head and neck cancer
This study uses a special 3D culture method to grow and analyze tumor cells from the blood of people with advanced head and neck cancer. It also includes healthy volunteers for comparison, to help researchers understand how these cells behave and improve future detection.
TaoyuanAges 18–80 - NCT06967961Recruiting
Looking for cancer cells that carry two markers in the blood
This trial is studying a special type of cell that shows up in the blood of people with certain advanced cancers. It aims to find out if these cells can help doctors better understand the cancer and guide treatment.
ToulouseAges 18 years+ - NCT07260370Recruiting
Studying blood markers in cancer patients on immunotherapy
This study looks at tiny particles (microRNA) and cancer cells in the blood of people with cancer who are getting immunotherapy. It aims to find patterns that might help doctors better understand how the treatment is working.
Taoyuan CityAges 20 years+ - NCT05889247Recruiting
Blood test guided monitoring for advanced lung cancer treatment
This trial checks whether a blood test that looks for cancer DNA can help guide and monitor treatment in people with advanced non-small cell lung cancer (NSCLC). It may help your team spot treatment response or changes earlier, so care can be adjusted appropriately.
Hillerød, Region HAges Any age - NCT07401316Recruiting
Tracking germ cell tumors with a blood test for cancer DNA
This trial looks for signs of cancer DNA in your blood (circulating tumor DNA) to see if it can help track germ cell tumors. It may help doctors find out if your cancer is coming back earlier.
Indianapolis, IndianaAges 18 years+ - NCT04520672Recruiting
