Purpose: Since 1995, the Korean Gastric Cancer Association (KGCA) has been periodically conducting nationwide surveys on patients with surgically treated gastric cancer. This study details the results of the survey conducted in 2023. Materials and Methods: The survey was conducted from March to December 2024 using a standardized case report form. Data were collected on 86 items, including patient demographics, tumor characteristics, surgical procedures, and surgical outcomes. The results of the 2023 survey were compared with those of previous surveys. Results: Data from 12,751 cases were collected from 66 institutions. The mean patient age was 64.6 years, and the proportion of patients aged ≥71 years increased from 9.1% in 1995 to 31.7% in 2023. The proportion of upper-third tumors slightly decreased to 16.8% compared to 20.9% in 2019. Early gastric cancer accounted for 63.1% of cases in 2023.Regarding operative procedures, a totally laparoscopic approach was most frequently applied (63.2%) in 2023, while robotic gastrectomy steadily increased to 9.5% from 2.1% in 2014.The most common anastomotic method was the Billroth II procedure (48.8%) after distal gastrectomy and double-tract reconstruction (51.9%) after proximal gastrectomy in 2023.However, the proportion of esophago-gastrostomy with anti-reflux procedures increased to 30.9%. The rates of post-operative mortality and overall complications were 1.0% and 15.3%, respectively. Conclusions The results of the 2023 nationwide survey demonstrate the current status of gastric cancer treatment in Korea. This information will provide a basis for future gastric cancer research.

Background: This study compares the difference in the clinical and radiologic outcomes when minimally invasive plate osteosynthesis (MIPO) technique is performed with or without using a positional screw in the treatment of humeral shaft fractures. Methods: From January 2010 to January 2021, a retrospective study was conducted on a total of 63 patients who underwent the MIPO technique for the treatment of humeral shaft fractures. We divided these patients into 2 groups: in group I, patients underwent MIPO without a positional screw; in group II, patients underwent MIPO with a positional screw. We compared functional outcomes including the American Shoulder and Elbow Surgeons score, University of California at Los Angeles score, Simple Shoulder Test, range of motion before and after surgery, operation time, blood loss, and complications. And we compared radiologic outcomes including pre- and postoperative anteroposterior (AP) and lateral displacement of the fracture and union time on plain radiographs. Results: The average patient age was 64.6 ± 15.1 years (range, 25–88 years). Group I consisted of 30 patients (10 men and 20 women), and group II consisted of 33 patients (11 men and 22 women). Between the 2 groups, there was no statistically significant difference in sex, body mass index, functional scores, AP and lateral displacement of the fracture on postoperative x-ray, operation time, and blood loss. In group II, a faster bony union was obtained than that in group I (4.6 vs. 6.4 months). Complications included 2 cases of transient radial nerve palsy in both groups and metallic failures (2 in group I and 1 in group II). Conclusions When performing MIPO for humeral shaft fractures, adding a positional screw could be more stabilizing than bridge plating without a positional screw, leading to faster bony union. A positional screw might help control interfragmentary movement without inhibiting essential interfragmentary movement for fracture healing.
