Young patient with a giant gastric bronchogenic cyst: A case report and review of literature.

Background: Gastric bronchogenic cysts (BCs) are extremely rare cystic masses caused by abnormal development of the respiratory system during the embryonic period. Gastric bronchial cysts are rare lesions that were first reported in 1956; as of 2023, only 33 cases are available in the PubMed online database. BCs usually have no clinical symptoms in the early stage, and imaging findings also lack specificity.

Rare metastasis of gastric cancer to the axillary lymph node: A case report.

Lymph node metastasis of gastric cancer is more common, metastatic lymph nodes are often around the stomach, and metastasis is carried out in a certain order, but gastric cancer metastasis to axillary lymph nodes is very rare. Due to the small number of patients with this kind of metastasis, its clinical features and treatment are not very clear. We initially thought that the enlarged axillary lymph nodes were inflammatory lesions.

[Variation and research progress of celiac trunk branch].

Celiac trunk is a wide and short ventral branch. It originates from the anterior abdominal artery at the level of L1 vertebra, and divides into three branches: the left gastric, common hepatic and splenic arteries, supplying the upper abdominal organs such as stomach, liver, spleen, pancreas, and duodenum. However, there are many types of branches variations.

Tumor size as a recommendable variable for accuracy of the prognostic prediction of gastric cancer: a retrospective analysis of 1,521 patients.

Background: It is still controversial whether tumor size (Ts) should be considered an important indicator for evaluation the prognosis of gastric cancer (GC). The purpose of this study was to elucidate the prognostic prediction superiority of Ts in the large-scale cohort of GC patients.

Methods: Data from 1,521 patients who underwent the curative resection were analyzed for demonstration the prognostic value of Ts.

Comparison of the staging of regional lymph nodes using the sixth and seventh editions of the tumor-node-metastasis (TNM) classification system for the evaluation of overall survival in gastric cancer patients: findings of a case-control analysis involving a single institution in China.

Background: It has recently been reported that the sixth edition of the tumor-node-metastasis (TNM) classification system for gastric cancer involving the staging of regional lymph nodes (N) has inappropriate cut-offs with regard to counts of metastatic lymph nodes. It remains controversial, however, as to whether the seventh edition of this classification system is completely accurate in staging N for the prediction of the prognosis of gastric cancer. Our aim was to determine which of these two editions of the TNM classification system was superior with regard to the prediction of the prognosis of Chinese patients with gastric cancer.

Prognostic value of number of examined lymph nodes in patients with node-negative gastric cancer.

Aim: To elucidate the potential impact of examined lymph nodes (eLNs) on long-term survival of node-negative gastric cancer patients after curative surgery.

Methods: A total of 497 node-negative gastric cancer patients who underwent curative gastrectomy between January 2000 and December 2008 in our center were enrolled in this study. Patients were divided into 4 groups according to eLNs through cut-point analysis.

Lymph node metastasis is mediated by suppressor of cytokine signaling-3 in gastric cancer.

Suppressor of cytokine signaling-3 (SOCS-3), a multifunctional cytokine, is able to inhibit cell growth and migration by blocking the Janus kinase signal transducers and activators of transcription signaling (JAK/STAT) activation in oncogenesis. Although the STAT-3 expression was associated with lymph node metastasis from gastric cancer (GC), the implication of SOCS-3 expression in GC is not clearly elucidated. In this study, SOCS-3, STAT-3, and pSTAT-3 were evaluated in GC tissues and adjacent non-tumor tissues of 107 patients who underwent curative surgery by immunohistochemistry.
