AI Article Synopsis
- - Gastric cancer is a significant cause of cancer-related deaths globally, and identifying high-risk individuals, particularly those with a family history, is essential for reducing mortality.
- - A systematic review and meta-analysis of 30 case-control studies revealed that individuals with first-degree relatives who have gastric cancer have a nearly threefold increased risk of developing the disease, though there is considerable variability in the results across studies.
- - The findings emphasize the importance of family history as a risk factor, suggesting it should be taken seriously for early detection and management of gastric cancer.
Article Abstract
Background: Gastric cancer ranks fourth in terms of global cancer-related deaths. Timely identification of high-risk populations is crucial to reduce mortality. Although a family history of gastric cancer increases risk, European and British guidelines report weak recommendations and low-quality evidence about the management of these patients.
Aim: To quantify the association in case-control studies of patients with gastric cancer with first-degree relatives with gastric cancer compared to those who do not.
Methods: We conducted a systematic review and meta-analysis of case-control studies up to November 2023. Data extraction was performed independently by two reviewers. The heterogeneity of effects across studies was quantified by I . We calculated odds ratios (OR) with 95% confidence intervals (CI) using random effects models.
Results: We included 30 studies in the systematic review. In all studies, a first-degree family history of gastric cancer represented a risk factor for gastric cancer. We included 21 studies on the risk of gastric cancer. There was a significantly increased association between gastric cancer and having first-degree relative(s) with gastric cancer, but with significant heterogeneity among studies (OR = 2.92; 95% CI 2.402-3.552; p < 0.001; I = 81.85%; p < 0.001).
Conclusion: This meta-analysis highlights the relevance of patients' family history of gastric cancer and the importance of this risk factor for the early detection of neoplastic conditions.

Comparative genomic analysis unveiling the mutational landscape associated with premalignant lesions and early-stage gastric cardia cancer.
Medicine (Baltimore)
January 2025
Department of Endoscopy, The Fourth Hospital of Hebei Medical University, Shijiazhuang, China.
This study enrolled 10 patients diagnosed with premalignant lesions and early-stage gastric cardia adenocarcinoma (GCA), confirmed through endoscopic examination. These patients were subjected to next-generation sequencing (NGS) using a customized 1123-gene panel to identify genetic alterations and signaling pathways. The results were compared to stage IIB to IV GCA samples from the cancer genome atlas (TCGA) and a cohort of Hong Kong patients.

Rationale: Solitary fibrous tumors (SFTs) are spindle cell tumors that typically occur in the pleura and peritoneum, but very rarely in the stomach. To our best knowledge, there are only 10 cases reported in English literature. We reported a case of primary stomach SFT and summarized the characteristics of all previous cases, suggesting that pathologists and surgeons should include this disease in the differential diagnosis list of primary mesenchymal tumor of the stomach.

Human epidermal growth factor receptor 2 (HER2) positive gastric cancer (GC) shows a robust response to the combined therapy based HER2-targeted therapy. The application of these therapies is highly dependent on the evaluation of tumor HER2 status. However, there are many risks and challenges in HER2 assessment in GC.

Background: Few studies have explored the genetic changes and clinicopathological features of stage II/III gastric cancer (GC) patients with no tumor recurrence, early recurrence, or late recurrence after curative surgery.
Methods: In this study, 376 patients who underwent curative surgery for stage II/III GC were analyzed. The clinical and genetic features of patients with no recurrence, early recurrence (<2 years), and late recurrence (≥2 years) were compared.

Importance: Upper gastrointestinal cancers such as gastric and esophageal cancers are rare malignancies with poor prognosis because it is usually diagnosed in latter stages. Presenting symptoms are frequently presumed pregnancy related rather than malignancy related. This review will raise awareness to consider these aggressive cancers in evaluating gastrointestinal complaints during pregnancy.
