Blood tests to guide gastric cancer treatment decisions
Part of Cancer, Digestive system clinical trials.
This study uses special blood tests to detect cancer DNA and help doctors decide the best treatment plan for gastric cancer. The goal is to improve outcomes by personalizing therapy based on how your cancer responds.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have gastric cancer (stomach or junction between stomach and esophagus) confirmed by biopsy or pathology
- You are at least 18 years old and well enough to tolerate treatment (ECOG score 0–2)
- Your blood counts, kidney, and liver function are adequate for cancer treatment
- You are willing to provide regular blood samples for circulating tumor DNA testing
- You fit one of three groups: planning neoadjuvant therapy before surgery, recovering after curative surgery, or have advanced/metastatic disease

This study looks for metabolic markers in your blood and tumor tissue to help find stomach cancer early, predict your prognosis, and watch for recurrence. If you qualify, you would give blood and tumor samples for testing.
This study tests a new way to guide treatment after surgery for stomach cancer. It uses a blood test to look for tiny pieces of cancer DNA, and then gives extra treatment only to people who still have signs of cancer. The goal is to prevent the cancer from coming back.
This study looks at stomach (or stomach–esophagus junction) cancer tissue, treatment details, and patient-reported experiences to better predict how you may respond to standard chemotherapy. It may help personalize future treatment by identifying markers that connect your tumor environment and your expected outcomes.
This study looks at proteins in your blood to find different types of stomach cancer. The goal is to match you with the best treatment before surgery, which may improve outcomes.
This study checks if a blood test can find leftover cancer DNA after stomach cancer surgery. It helps doctors know if more treatment is needed.
This trial is testing whether using a blood test to find tiny amounts of cancer DNA after initial treatment can guide decisions about further therapy for people with stomach cancer. The goal is to personalize follow-up treatment to reduce the chance of cancer returning.
