To discuss the relationship between the clinicopathological data, long-term survival of gastric cancer patients and different expression levels of Cyclin-Dependent Kinase 5 (CDK5) and Protein Phosphatase 2A (PP2A). The expression levels of CDK5 and PP2A were detected by immunohistochemistry in specimens from 124 patients with primary gastric cancer. The correlation among the expression of CDK5 and PP2A, clinicopathological factors and prognosis was investigated. The expression level of CDK5 was correlated with the TNM stage (p=0.030) and N stage (p=0.001), while the expression level of PP2A was correlated with the TNM stage and N stage (p=0.001 and p=0.004) as well as the degree of differentiation (p=0.046). The expression of CDK5 was positively correlated with the expression of PP2A in gastric cancer. Co-expression of CDK5 and PP2A is an independent prognostic factor that affected overall survival, and provided more accurate prognostic value for the overall survival of gastric cancer patients. The expression of CDK5 and PP2A is positively correlated in gastric cancer. Co-expression of CDK5 and PP2A was an independent prognostic factor in patients with gastric cancer.

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.
Gastric and Esophageal Cancer in Pregnancy: A Review.

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.
