We developed a nomogram predicting 5- and 10-year overall survival after D2 gastrectomy for gastric cancer. Validation using the SNUH and CIAH data sets revealed good discrimination and calibration, suggesting good clinical utility. The nomogram improved individualized predictions of survival.

For middle-third EGC, LAPPG can be considered as a better treatment option than LADG in terms of nutritional advantage and lower incidence of gallstone.

To evaluate the postoperative prognosis of AEJ within the stomach, AEJ II and AEJ III should be considered a part of gastric cancer irrespective of EGJ involvement.

The present study provides evidence that in patients with M1 gastric cancer which confined to one site who respond well to induction chemotherapy, a higher rate of R0 resection and longer survival can be expected. A multicenter cohort study is needed to explore this concept further.

Abstract Background The prognostic potential of PD-L1 is currently unclear in gastric carcinomas, although the immune checkpoint PD-1/PD-L1 inhibitors have produced promising results in clinical trials. Methods We explored the prognostic implications of programmed death ligand 1 (PD-L1) in 514 consecutive surgically-resected gastric carcinomas. Overall survival and recurrence-free survival were evaluated. Immunohistochemistry for PD-L1, CD8, FOXP3, and PD-1, and molecular grouping by in situ hyb

Our study verified that advanced stage, high preoperative NLR (NLR ≥ 1.7), and old age (≥ 70 years) are significant, independent prognostic factor for overall survival in patients with gastric cancer.

A specific problem in the preservation of goat semen has been the detrimental effect of seminal plasma on the viability of spermatozoa in extenders containing egg yolk or milk. The use of chemically defined extenders will have obvious advantages in liquid storage of buck semen. Our previous study showed that the self-made mZAP extender performed better than commercial extenders, and maintained a sperm motility of 34% for 9 days and a fertilizing potential for successful pregnancies for 7 days. T

The prevalence of gastroesophageal reflux disease (GERD) is increasing in Korea, and physicians, including surgeons, have been focusing on its treatment. Indeed, in Korea, medical treatment using a proton pump inhibitor is the mainstream treatment for GERD, while awareness of surgical treatment is limited. Accordingly, to promote the understanding of surgical treatment for GERD, the Korean Anti-Reflux Surgery Study Group published the Evidence-Based Practice Guideline for the Surgical Treatment

Elderly patients' global health status/quality of life and social functioning significantly decreased at postoperative 1 month and recovered by 6 months after gastrectomy. There was a significant age-specific difference in physical functioning throughout the 1-year follow-up. Surgeons need to pay more attention to recovery of the elderly patients' HRQoL after gastrectomy.

Our study reveals novel finding indicating that IFN-γ signaling pathway is retained in Tex and pTex of MSI-H gastric cancer, offering a comprehensive perspective for future investigations into immunotherapy for gastric cancer.

The surgical outcomes of DPLDG and TPLDG did not differ. Regarding fewer incisions, DPLDG can be an alternative option for TPLDG.

Research activities are being carried out through many collaborative writing activities in various disciplines. However, there is minor research on collaborative research in the field of architecture, although meaningful results can be drawn in many ways. Therefore, in this study, we used technology statistics and social network analysis (SNA) to investigate cooperative relationship for collaborative research analysis from the Architectural planning committee of the Korean Institute of Architect

Despite the recent increase in the use of complementary and alternative medicine (CAM)among the general population and patients, little is known about Korean physicians’attitudes about and interest in CAM. We conducted a web-based survey of knowledge, attitude,and experience in CAM among primary care physicians (PCPs) and academic physicians (APs)in Korea. A total of 826 physicians (341 PCPs and 485 APs) responded. Respondents in both groups felt that they were not sufficiently knowledgeable abo
