Abstract

Purpose
The Korean Gastric Cancer Association (KGCA) has been conducting nationwide surveys on patients with surgically treated gastric cancer, every 5 years, since 1995. This study details the results of the survey conducted in 2019.
Materials and Methods
This survey was conducted from March to December 2020 using a standardized case report form, which was sent to every member of the KGCA via e-mail. We collected data on 54 items, including patient demographics, tumor characteristics, surgical procedures, and surgical outcomes. We compared the results of the 2019 survey with previous surveys.
Results
Data of 14,076 cases were collected from 68 institutions. The mean patient age was 62.9 years and the proportion of patients who were aged ≥71 years increased from 9.1% in 1995 to 28.8% in 2019. The proportion of upper-third tumors steadily increased from 11.2% in 1995 to 20.9% in 2019 and that of early gastric cancer increased from 57.7% in 2009 to 63.6% in 2019. Regarding operative procedures, a total laparoscopic approach was used in more than half of the cases (55.1%) in 2019. The most common anastomotic method was the Billroth II procedure (45.0%) after distal gastrectomy and double tract reconstruction (81.2%) after proximal gastrectomy in 2019. The postoperative mortality rate was 1.0%, and the overall postoperative complication rate was 14.5%.
Conclusions
The results of the 2019 nationwide survey demonstrate the current status of gastric cancer treatment in Korea. This information will provide a basis for gastric cancer research in the future.
