Pulmonary lymphangitic carcinomatosis (PLC) is a well-known form of tumour metastasis to the pulmonary lymphatic system or to the adjacent interstitial tissue resulting in thickening of the bronchovascular bundle and septa. Another type of tumour metastasis to the lung involves the pulmonary vascular system and is known as pulmonary tumour thrombotic microangiopathy (PTTM). In this article, we will describe the unusual case of a young Chinese woman with gastric adenocarcinoma revealed by atypical radiographic lesions consistent with both PLC and PTTM. We will discuss the existing evidence and hypotheses about the pathophysiology of both conditions.

Autoimmune gastritis (AIG) is a chronic inflammatory condition characterized by immune-mediated destruction of gastric parietal cells, leading to oxyntic atrophy, achlorhydria, and hypergastrinemia. While AIG was historically linked to gastric adenocarcinoma and type I neuroendocrine tumors (NETs), recent evidence suggests the risk of adenocarcinoma in AIG is lower than previously believed, particularly in Helicobacter pylori (H. pylori)-negative patients.

Cyclin-Dependent Kinase (CDK) 12 is a member of the 20-membered CDK family (CDK1-20) and plays a vital role in regulating gene transcription, mRNA splicing, translation, cell cycle, and repair of DNA damage. CDK12 is an emerging therapeutic target due to its role in regulating the transcription of DNA Damage Response (DDR) genes in Cyclin-Dependent Kinase (CDK). However, the development of selective small molecules targeting CDK12 has been challenging due to the high degree of homology between kinase domains of CDK12 and other transcriptional CDKs, most notably CDK13.

Background: Adenocarcinoma of the esophagogastric junction (AEGJ) is a highly aggressive tumor that frequently metastasizes to the liver. Understanding the cellular and molecular mechanisms that drive this process is essential for developing effective therapies.
Methods: We employed single-cell RNA sequencing to analyze the tumor heterogeneity and microenvironmental landscape in patients with AEGJ liver metastases.

Gastric cancer is the fourth most common malignancy in Korea and remains the fifth and seventh leading cause of cancer death in males and females, respectively. Although the survival rates for gastric cancer have improved, unresectable or metastatic gastric cancer still has an abysmal prognosis, and the five-year survival rate for patients with stage IV gastric cancer is approximately 6.6% in Korea.

Surgical resection and lymphadenectomy are the mainstay of curative treatment for oesophagogastric cancer. In this study we evaluate the results of intravascular methylene blue injection into oesophagectomy and gastrectomy specimens as a tool to increase lymph node detection. A prospective and descriptive study was run on 24 patients (11 oesophagus, 13 stomach cases).
