Gastroesophageal junction cancer

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 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 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 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…
