Pembrolizumab in patients with gastric cancer and liver metastases: A paradigm shift in immunotherapy.

In this editorial, we explore the impact of immunotherapy and its safety in patients with advanced gastric cancer (GC) and liver involvement. GC, a formidable adversary in the oncology landscape, presents its most challenging battlefront when it reaches stage IV, often characterized by liver metastases. The prognosis for patients at this advanced stage is daunting, with systemic chemotherapy traditionally offering a median overall survival slightly over a year. However, the landscape of treatment is evolving, with new strategies and therapies offering a glimmer of hope.
