The objective of the current study was to investigate the expression pattern of Tbx3 and its clinicopathological significance in patients with gastric cancer. The expression pattern of Tbx3 in gastric cancer tissues and adjacent noncancerous surface epithelia and mucosal glands was detected by immunohistochemistry. Tbx3 was found to be overexpressed in 46 of 98 human gastric cancer samples, and this correlated with advanced clinical stage, tumor stage, and nodal status. In addition, in the SGC-7901 gastric cancer cell line, Tbx3 overexpression by plasmid transfection promoted growth and invasion. Conversely, depleting Tbx3 expression by small-interfering RNA inhibited proliferation and invasion in BGC-823 cell line. Moreover, Tbx3 accelerated cell cycle progression at the G1/S boundary. Tbx3 also regulated epithelial-to-mesenchymal transition (EMT) to promote cell invasion by repressing E-cadherin expression and increasing expression levels N-cadherin, vimentin. These results indicate that in gastric cancer, Tbx3 plays an important role and might be a useful therapy target.

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.
