Long-term relative survival of patients with gastric cancer from a large-scale cohort: a period-analysis

Q: What was the main purpose of the period analysis in this study?

To assess how gastric cancer treatment and outcomes at the center changed over the past 15 years using period analysis and 5-year relative survival rates.

Q: Which patient group and time range were analyzed?

A cohort of 3915 gastric cancer patients from Nanfang Hospital was analyzed over 15 years, spanning 2008 to 2022.

Q: What were the key findings about 5-year relative survival?

The center’s 5-year relative survival rate increased notably, reaching 71.4% from 2018 to 2022, with improvements across age groups and generally by tumor stage, including stage IV.

Q: What factors does the paper suggest explain the survival improvement?

Improvement is attributed to standardized surgical techniques, perioperative management, and immunotherapy, supported by the study’s survival data.

Gastric cancer remains a major global health challenge. This study applies period analysis to quantify how gastric cancer treatment and outcomes at Nanfang Hospital, Southern Medical University changed over the past 15 years. Survival status for 3915 patients from 2008–2022 was evaluated using 5-year relative survival rates. Results show marked improvement in 5-year survival, especially from 2018–2022, with progress linked to standardized surgery, perioperative management, and immunotherapy.

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.

According to the latest report from the Global Cancer Statistics Database, gastric cancer ranks fifth in global cancer incidence and fourth in cancer mortality, highlighting its substantial impact on public health [1]. Gastric cancer incidence is significantly higher in East Asia and Eastern Europe, while lower in North America, Northern Europe, and Africa. This global disparity is likely due to a combination of environmental, genetic, and infectious factors [2]. Although the incidence of gastric cancer has declined in © The Author(s) 2024.
