Blood Test to Guide Colorectal Cancer Follow-Up Treatment
This trial tests whether a special blood test that detects cancer DNA can help doctors decide if you need additional chemotherapy after colorectal cancer surgery. The goal is to personalize treatment based on your individual risk rather than giving chemotherapy to everyone.
ShanghaiAges 18–80 - NCT07562711RecruitingPhase 2
Blood Test to Guide Chemotherapy After Colon Cancer Surgery
This study uses a simple blood test to detect cancer DNA after surgery for early-stage colon cancer. The goal is to help doctors decide whether chemotherapy is truly needed based on the blood test results, rather than giving it to everyone.
ShanghaiAges 18–80 - NCT07546578Recruiting
Measuring tumor DNA in blood samples from ovarian cancer patients
This study looks at blood samples from people with ovarian cancer to measure a marker called ctDNA (bits of tumor DNA in the blood). The goal is to see if changes in this marker before and after surgery can help predict or monitor the cancer.
RomaAges 18 years+ - NCT07393048Recruiting
Personalized ctDNA test to predict rectal cancer treatment response
This trial uses a personalized blood test (ctDNA-MRD) to see how well neoadjuvant therapy works for rectal cancer. If you have stage II or III rectal cancer that can be surgically removed, this study might help guide your treatment.
Beijing, Beijing MunicipalityAges 18–75 - NCT07394218RecruitingPhase 2
Tumor DNA Blood Test to Guide Breast Cancer Treatment
This trial tests whether using a blood test for tumor DNA can help doctors decide the best treatment for people with HER2-negative breast cancer that has spread. It focuses on a type of therapy called an antibody-drug conjugate (ADC) and aims to personalize your care.
Shanghai, Shanghai MunicipalityAges 18–75 - 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 - NCT07375316RecruitingPhase 2
Combination therapy for EGFR-mutated lung cancer with lingering ctDNA
This trial tests if adding sacituzumab tirumotecan to osimertinib works better than osimertinib alone for advanced lung cancer that still shows cancer DNA (ctDNA) in the blood after initial osimertinib treatment.
Guangzhou, GuangdongAges 18 years+ - NCT07310537Recruiting
Liquid biopsy trial for colorectal cancer liver metastases
This study tests whether a simple blood sample from your finger can detect tumor DNA as well as a standard blood draw. It is designed for people with colorectal cancer that has spread to the liver and hasn't responded to treatment.
