- Helicobacter pylori-naive gastric cancer (HPnGC) is an emerging clinical entity with increasing global incidence.
- HPnGC is linked to specific etiologies like Epstein-Barr virus, autoimmune gastritis, and hereditary cancer syndromes.
- It is characterized by aggressive histological subtypes, unfavorable locations, advanced stages at diagnosis, and poorer prognosis compared to H. pylori-positive gastric cancer.
- Diagnosis requires stringent multi-modal confirmation of absent H. pylori infection.
- Current treatments for HPnGC are similar to those for H. pylori-positive gastric cancer, including endoscopic, surgical, and systemic approaches.
- There is a need for standardized diagnostic criteria and further research into molecular subtypes and carcinogenic mechanisms.
- Future research should focus on cost-effective surveillance methods and effective treatment strategies to develop comprehensive clinical guidelines.
