AI Article Synopsis
- Previous studies indicated that gastric cancer survivors face a higher risk of osteoporotic fractures, but the impact of different surgery types wasn't thoroughly analyzed.
- This study analyzed data from 85,124 gastric cancer survivors and categorized them by surgical type—total gastrectomy (TG), subtotal gastrectomy (SG), and endoscopic procedures (ESD/EMR)—to compare fracture incidence.
- The findings revealed that TG significantly increases the risk of osteoporotic fractures compared to SG and ESD/EMR, suggesting that the extent of gastric removal and its metabolic effects contribute to this increased risk.
Article Abstract
Purposes: Previous studies have suggested that there is an increased risk of osteoporotic fracture in gastric cancer survivors. However, the data was not classified according to surgery type. This study investigated the cumulative incidence osteoporotic fracture (OF) in gastric cancer survivors according to treatment modality.
Methods: A total of 85,124 gastric cancer survivors during 2008-2016 were included. The type of surgery was classified as total gastrectomy (TG, n = 14,428)/subtotal gastrectomy (SG, n = 52,572)/endoscopic mucosal dissection and endoscopic mucosal resection (ESD/EMR, n = 18,125). The site of osteoporotic fractures included the spine, hip, wrist, and humerus. We examined cumulative incidence using Kaplan-Meier survivor analysis and cox proportional hazards regression analysis to determine the risk factor of OF.
Results: The incidence of OF per 100,000 patient year was 2.6, 2.1, 1.8 in TG, SG, ESD/EMR group. The cumulative incidence rate was 2.3% at 3 years, 4.0% at 5 years, and 5.8% at 7 years in gastrectomy group, and 1.8% at 3 years, 3.3% at 5 years in the SG group, and 4.9% at 7 years postoperatively in ESD/EMR group. TG increased the risk of OF compared to patients who underwent SG (HR 1.75, 95% confidence interval [CI] 1.57-1.94), and ESD/EMR (hazard ratio [HR] 2.23, 95% CI 2.14-2.32).
Conclusion: Gastric cancer survivors who underwent TG had an increased osteoporotic fracture risk than did SG or ESD/EMR in these patients. The amount of gastric resection and accompanying metabolic changes seemed to mediate such risk. Additional research is needed to establish an optimal strategy for each type of surgery.

Purpose: Gastric cancer (GC) remains a major malignancy. Robotic gastrectomy (RG) has gained popularity due to various advantages. Despite those advantages, many hospitals lack the necessary equipment for RG and are still performing laparoscopic gastrectomy (LG) due to its established minimal invasiveness and safety.

Poor response to 5-fluorouracil (5-FU) remains an obstacle in the treatment of gastric cancer (GC). Super enhancers (SEs) are crucial for determining tumor cell survival under drug pressure. SE landscapes related to 5-FU-resistance are mapped to GC using chromatin immunoprecipitation-sequencing (ChIP-Seq).

Background And Study Aims: Diffuse infiltrative gastric cancer can be difficult to diagnose owing to a lack of endoscopic features in the superficial mucosa. Moreover, a forceps biopsy may not reveal a pathological diagnosis. We aimed to evaluate the diagnostic yield and safety of endoscopic mucosal resection (EMR) and 'open-lid submucosal biopsy', a technique wherein EMR followed by biopsy of the ulcer floor is performed for a pathological diagnosis.

Background: To investigate the effect of postoperative supplementary parenteral nutrition (SPN) containing varying energy intake levels during the early postoperative period on the clinical outcomes of patients diagnosed with gastric cancer.
Methods: Data from 237 patients, who were diagnosed with gastric cancer between January 2016 and June 2022, were retrospectively analyzed. Patients were divided into 2 groups based on mean daily SPN energy intake: low (L-SPN; < 20 kcal/kg/day); and high (H-SPN; ≥ 20 kcal/kg/day).
