Background
Gastric cancer poses a significant global health challenge. We aim to use period analysis to assess the changes in gastric cancer treatment at our center over the past 15 years. This study reflects the current state of gastric cancer treatment at our center and provides valuable data to support clinical advancements.
Method
We used period analysis to evaluate the survival status of 3915 patients with gastric cancer at Nanfang Hospital, Southern Medical University, over a 15-year period spaning from 2008 to 2022. The 5-year relative survival rates were analyzed.
Result
Our findings indicate that the 5-year relative survival rate at our center from 2018 to 2022 is 71.4%. From 2018 to 2022, the 5-year relative survival rates for patients aged < 40, 40–54, 55–69, and ≥ 70 reached 67.5%, 73.5%, 72.0%, and 67.1%, respectively. For stage IV patients, the 5-year relative survival rate reached 29% in 2018–2022. For stage I-III patients, the 5-year relative survival rate reached 89.7% in 2018–2022. The five-year relative survival rate for patients who underwent laparoscopic surgery at our center rose from 50.3% in 2008–2012 to 71.4% in 2018–2022. Overall, there has been a notable increase in the 5-year relative survival rates, regardless of age, gender, region, or tumor stage.
Conclusion
Period analysis over the past 15 years shows significant improvement in the 5-year survival rate for gastric cancer at our center. This progress is due to standardized surgical techniques, perioperative management, and immunotherapy, providing robust data for evaluating the efficacy of recent treatments.
