Korean Gastric Cancer Association-Led Nationwide Survey on Surgically Treated Gastric Cancers in 2019

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.
