Recent findings reveal that immune checkpoint inhibitors (ICIs) significantly improve treatment outcomes for advanced gastric adenocarcinoma (GAC), especially in patients with specific molecular subtypes such as MSI-H and HER2-positive. Combining ICIs with chemotherapy or targeted therapies enhances efficacy, despite the risk of immune-related adverse events (IRAEs). The study emphasizes the need for effective management strategies […]

Higher OLGA and OLGIM stages increase gastric cancer risk.
Higher stages of the OLGA and OLGIM staging systems significantly correlate with an elevated risk of developing high-grade dysplasia (HGD) and gastric cancer (GC). A systematic review and meta-analysis of eight prospective cohort studies found that moving from OLGA/OLGIM categories 0-II to III-IV notably increases the likelihood of these outcomes. This validates the use of […]
Nomogram effectively predicts intra-abdominal infection risk post-gastrectomy
A nutrition-based nomogram has been developed to predict the risk of intra-abdominal infection (IAI) after D2 radical gastrectomy for gastric cancer. An analysis of 404 patients identified key indicators, including the NRS2002 score, fasting blood glucose, and multi-visceral resection, associating them with IAI risk. The nomogram demonstrated good predictive capacity (AUROC 0.744) and excellent calibration, […]
Amino acid profiles may predict postoperative recovery in gastric cancer patients.
Significant preoperative amino acid elevations were found in gastric cancer patients. Post-surgery, many amino acids decreased but were partially restored with nutritional intervention, with some levels surpassing preoperative values. However, methionine and glutamine remained lower than in healthy individuals. Correlations were identified between specific amino acid changes and faster gastrointestinal recovery as well as reduced […]
Robotic technique improves safety in gastric conduit reconstruction
A novel robotic approach for the retrosternal route in gastric conduit reconstruction has demonstrated safety and efficiency. In a study involving 43 esophageal cancer patients, the median time for creating this route was just nine minutes, with no incidences of pleural injury or postoperative hemorrhage reported. Additionally, there was no significant variation in creation time […]
Navigation system improves robotic gastrectomy outcomes for novices
A vascular navigation system significantly enhances robotic distal gastrectomy for novice surgeons, according to a study involving 49 patients. The navigation group showed reduced dissection times (179.85 vs. 204.87 minutes) and increased lymph node retrieval (41.81 vs. 30.96). Additionally, the system contributed to lower C-reactive protein levels, indicating reduced surgical trauma (8.27 vs. 11.68 mg/dl). […]
ICG-guided lymphadenectomy improves survival in gastric cancer
A study involving 459 gastric cancer patients showed that indocyanine green (ICG)-guided lymphadenectomy significantly enhanced survival outcomes after neoadjuvant chemotherapy. Patients in the ICG group had a higher number of lymph nodes harvested and demonstrated improved three-year overall survival (78.6% vs 66.6%) and recurrence-free survival (74.0% vs 57.0%) compared to non-ICG counterparts. Efficacy was particularly […]
Nomograms Enhance Prognostic Accuracy in Early Gastric Cancer with Lymph Node Metastasis
A study established two nomograms to predict risks and prognosis for T1-T2 stage gastric cancer patients with lymph node metastasis. Analyzing data from 5,350 patients, key risk factors included age, tumor size, and grade. The developed nomograms demonstrated excellent calibration and clinical applicability, significantly distinguishing overall survival between low-risk and high-risk groups. These tools aim […]
New prognostic score improves survival predictions in gastric cancer
A novel prognostic oxidative stress-immune-inflammation score (posii score) has been developed to enhance survival predictions for gastric cancer patients post-radical gastrectomy. Analysis of 3,612 patients revealed that those in the low posii group exhibited significantly higher 5-year overall and disease-free survival rates, along with reduced recurrence risks (p < 0.05). Two validated online calculators based […]
Neoadjuvant immunochemotherapy shows promising outcomes in esophageal cancer.
A multicenter retrospective study evaluated neoadjuvant immunochemotherapy involving PD-1 agents plus platinum-based chemotherapy for 213 patients with resectable esophageal cancer. The study reported a high pathological complete response (PCR) rate of 31.9%, with a complete tumor resection (R0) rate of 99.1%. Additionally, two-year disease-free survival (DFS) and overall survival (OS) rates were notable at 78.9% […]
