Typically, early-onset gastric cancers (EOGC) present at the age of 45 years old or younger. Although its prevalence ranges from 2.7% to 15% depending on the population being studied, it is generally accepted that 10% of gastric cancers (GCs) fall into this category.


Conclusions: As explained above EOGC is a growing health concern that affects young individuals. Furthermore, the reported case displayed a poor response to standard therapy including checkpoint inhibitors and chemotherapy despite the presence of biomarkers that predict a favorable outcome. Future studies should adopt alternative approaches to find novel, more effective therapies.
