Objectives: This study examines trends in age, gender, tumor location, histology, stage, and treatment of gastric can cer patients at Kayseri City Hospital from 2018 to 2023. Methods: Patients registered with ICD-10 code C16 from January 2018 to December 2023 were included. Data were analyzed retrospectively, excluding those without a malignant diagnosis or sufficient data. Patients were categorized by age, tumor location, histology, stage, and treatment type. Results: The study included 804 patients (269 females, 535 males) with a mean age of 62.69±13.04 years. The most common tumor location was the antrum, pylorus, and incisura angularis. Histologically, 64.3% had adenocarcinoma, 16.8% had signet ring cell carcinoma, 4.2% had neuroendocrine tumors, and 5.7% had gastrointestinal stromal tumors. Diagnostic stages were 21.8% localized, 36.4% regional, 32.1% metastatic, and 9.7% unknown. Conclusion: The study highlights trends in gastric cancer at Kayseri City Hospital. A decline in incidence since 2018, with the lowest in 2020, suggests the impact of the COVID-19 pandemic on hospital admissions. Gastric cancer was more common in males. An increase in metastatic stage diagnoses during the pandemic reflects delayed hospital visits. The findings emphasize the importance of early diagnosis and monitoring trends for better prevention and treatment strategies. Keywords: Gastric cancer, incidence
