Gastroesophageal cancer

Researchers are running a first-in-human study of MGC030, an antibody-drug conjugate, in people with advanced solid tumors that have come back or stopped responding to standard treatment. The trial includes participants with urothelial, colorectal, gastric, gastroesophageal, esop…

This study looks at how zanidatamab, a targeted drug for HER2-positive gastroesophageal cancer, is used in real-world clinical practice. Researchers will track about 300 adults with advanced or metastatic disease who are starting zanidatamab as their first treatment, recording pa…

This study tests whether people with certain gastrointestinal cancers—like stomach, esophageal, or colorectal—can safely skip radical surgery after responding well to precision therapies such as immunotherapy or targeted drugs. Participants with specific molecular markers will be…

This phase II trial is testing whether adding a type of precise radiation called stereotactic body radiation therapy (SBRT) to standard immunotherapy can help people with stage IV cancers, including head and neck, lung, cervical, esophageal, and gastric cancers. Participants will…

This early-phase trial tests whether adding two targeted drugs (zanidatamab and tislelizumab) to standard chemotherapy can completely eliminate HER2-positive gastroesophageal cancer before surgery. About 29 adults with operable, locally advanced disease will receive the combinati…

This phase 3 trial will compare two surgical techniques for esophageal cancer: totally minimally invasive esophagectomy (TMIE) using only keyhole incisions, versus a hybrid approach that combines keyhole and open chest surgery. The study aims to see if TMIE reduces severe complic…

This study tests the drug Enhertu in 43 people with newly diagnosed HER2-positive stomach, esophageal, or gastroesophageal junction cancer that has spread. Participants have a lower physical ability (ECOG 2) and will receive Enhertu by IV every 3 weeks. The main goal is to see ho…

This study tests a new drug called TST001 added to standard chemotherapy and immunotherapy for people with advanced stomach or gastroesophageal junction cancer that has not been treated before. The goal is to see if the combination helps control the tumor longer and improves surv…

This study compares a new, less invasive surgery that removes only the cancerous upper part of the stomach to the standard full stomach removal. The goal is to see if the new approach helps patients lose less weight one year after surgery. The trial will enroll 120 adults with ea…

This study tests a new PET imaging tracer, [68Ga]Ga-NODAGA-SNA014, to detect a protein called Claudin18.2 in pancreatic and stomach cancers. The goal is to see if the scan can accurately identify patients whose tumors have this protein, which could help doctors choose the right t…

This study tests a new breath test to detect cancers of the stomach and esophagus. Participants provide a breath sample before and after drinking a special liquid. The test looks for chemicals in the breath that may signal cancer. The goal is to see if the drink makes these chemi…

This observational study tracks how patients with stage II to IVB gastric or gastroesophageal junction cancer are actually treated in routine clinical practice across Greece. Researchers will collect data on patient characteristics, treatment choices, timing of therapies, and bio…

This study tests whether a personalized blood test (Signatera) can identify gastric cancer patients who, after surgery, have no detectable cancer DNA and can safely receive a milder immunotherapy (durvalumab) instead of standard chemotherapy. About 1000 adults with stage II-IVa g…
