Proximal Versus Total Gastrectomy for Locally Advanced Siewert Type II-III Gastroesophageal Junction Cancer

This multicenter prospective randomized clinical trial aims to compare the safety and oncological effectiveness of proximal gastrectomy and total gastrectomy in patients with locally advanced Siewert type II-III gastroesophageal junction cancer. Eligible patients will be randomly assigned to undergo either proximal gastrectomy or total gastrectomy using open, laparoscopic, or robotic surgical approaches according to clinical suitability. The primary outcome of the study is 3-year disease-free survival. Secondary outcomes include postoperative mortality, postoperative complications, and the number of metastatic lymph nodes retrieved. Patients will be followed for up to five years after surgery to evaluate long-term oncological outcomes.

CA-4948 in Combination With FOLFOX/PD-1 Inhibitor +/- Trastuzumab for Untreated Unresectable Gastric and Esophageal Cancer

This is a phase I trial of CA-4948 in combination with FOLFOX/PD-1 inhibitor with or without trastuzumab for unresectable gastric, GEJ, and esophageal cancer. During the Dose Escalation portion of the study, different dose levels of CA-4948 in combination with FOLFOX/nivolumab will be evaluated by BOIN algorithm. Dose Expansion will include Cohorts A and B. Expansion Cohort A will enroll up to 12 patients with HER2 negative gastric, GEJ, and esophageal cancer at the expansion dose of CA-4948 determined during Dose Escalation and will use the same treatment regimen of FOLFOX/nivolumab. Expansion Cohort B will investigate CA-4948 at the dose determined during Dose Escalation in combination with FOLFOX/pembrolizumab and trastuzumab in up to 12 patients with HER2 positive disease; however, the initial 6 patients will be considered safety lead-in to confirm the safety and tolerability of this combination; if determined to be safe, an additional 6 patients will be enrolled for a total of 12 in Cohort B.

A Study to Learn About the Study Medicine Called PF-08634404 in Combination With Chemotherapy in Gastroesophageal Cancer

This study is being done to learn more about a new medicine called PF-08634404 and how well it works when given with chemotherapy to people with gastroesophageal cancer that is locally advanced (spread to nearby tissues) or has spread to other parts of the body. To join the study, participants must meet the following conditions: Be 18 years or older. Have locally advanced or metastatic gastric, gastroesophageal junction or esophageal adenocarcinoma Be treatment naïve for advanced or metastatic disease Be in good physical condition and have healthy organs based on medical tests. The study has two parts: * In the first part, researchers will check how safe the study medicine in combination with chemotherapy is and how well people respond to it. * In the second part, they will compare study medicine plus chemotherapy to another approved treatment (nivolumab plus chemotherapy) to see which works better. The treatment will be given in repeated time periods called cycles.

Iparomlimab and Tuvonralimab (QL1706) Combined With Chemotherapy for Previously Untreated Advanced or Metastatic Gastric or Gastroesophageal Junction Cancer

The goal of this Phase II clinical trial is to evaluate the efficacy and safety of Iparomlimab and Tuvonralimab (QL1706) combined with SOX chemotherapy (S-1 plus Oxaliplatin) in patients with previously untreated advanced or metastatic gastric cancer or gastroesophageal junction cancer. The main questions it aims to answer are: 1、What is the objective response rate (ORR) of the combination of QL1706 and SOX chemotherapy? 2、What are the safety and tolerability of this combination therapy? Participants will: 1. Receive Iparomlimab and Tuvonralimab (QL1706) via intravenous infusion every 3 weeks. 2. Receive SOX chemotherapy (Oxaliplatin via intravenous infusion on Day 1 and S-1 orally twice daily for 14 days) every 3 weeks for up to 6 cycles. 3. Continue maintenance therapy with QL1706 combined with S-1 after 6 cycles until disease progression or unacceptable toxicity. 4. Undergo tumor imaging assessments (CT or MRI) every 6 weeks for the first 24 weeks, and then every 9 weeks thereafter to monitor the disease.

The Efficacy and Safety of Laparoscopic Proximal Gastrectomy With LPG-tbROSF Versus LTG for Localized Proximal Gastric Cancer.

This clinical trial is evaluating a new, function-preserving surgical technique for patients with early-stage cancer in the upper part of the stomach. The current standard treatment is a Laparoscopic Total Gastrectomy (LTG), which involves the complete removal of the stomach. This study compares the standard LTG with an innovative procedure called Laparoscopic Proximal Gastrectomy combined with a novel anti-reflux reconstruction (LPG-tbROSF). This new technique removes only the cancerous upper portion of the stomach, aiming to preserve digestive functions and reduce post-surgery complications like acid reflux. The main goal is to see if patients who receive the new, stomach-preserving surgery experience less body weight loss one year after the procedure compared to those who undergo the standard total gastrectomy. The research will also compare the two surgeries in terms of post-operative quality of life, nutritional status, acid reflux symptoms, safety, and long-term cancer outcomes. The study is a multi-center, prospective, randomized controlled trial that plans to enroll 120 patients with localized cancer in the upper stomach.

Safety and Efficacy of Pembrolizumab in Combination With FLOT About Gastroesophageal Junction Cancer:

At present, surgery is still the main treatment for gastroesophageal junction cancer. At the same time, multimodal comprehensive treatment such as chemotherapy and molecular targeted therapy can effectively alleviate pathological progression, facilitate R0 resection and improve the overall survival of patients.Pembrolizumab, as a PD-1 inhibitor, has been shown to have antitumor activity and a manageable safety profile in gastroesophageal junction cancer.Pembrolizumab combined with chemotherapy has become a research hotspot. However, to date, there is no clinical study related to gastroesophageal junction cancer. In this study, Pembrolizumab combined with FLOT was used as the first-line treatment for gastroesophageal junction cancer, aiming to explore the experience chemotherapy mode for gastroesophageal junction cancer.
